ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law provides in general
that a corporation may indemnify its directors, officers, employees or agents
against expenditures (including judgments, fines, amounts paid in settlement and
attorneys' fees) made by them in connection with certain lawsuits to which they
may be made parties by reason of their being directors, officers, employees or
agents and shall so indemnify such persons against expenses (including
attorneys' fees) if they have been successful on the merits or otherwise.  The
bylaws of Adelphia provide for indemnification of the officers and directors of
Adelphia to the full extent permissible under Delaware law.

     Adelphia's Certificate of Incorporation also provides, pursuant to Section
102(b)(7) of the Delaware General Corporation Law, that directors of Adelphia
shall not be personally liable to Adelphia or its stockholders for monetary
damages for breach of fiduciary duty as a director for acts or omissions after
July 1, 1986, provided that directors shall nonetheless be liable for breaches
of the duty of loyalty, bad faith, intentional misconduct, knowing violations of
law, unlawful distributions to stockholders, or transactions from which a
director derived an improper personal benefit.

ITEM 17.  UNDERTAKINGS

     (a) Rule 415 Offering.

     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;

                                    ALTII-2
<PAGE>
 
          (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 the Registration Statement;

          (iii)  To include any material information with respect to the plan of
distribution not previously disclosed in the Registration Statement or any
material change to such information in the Registration Statement;

Provided, however, that paragraphs (1)(i) and (1)(ii) above do not apply if the
Registration Statement is on Form S-3 or Form S-8, and 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) Filings Incorporating Subsequent Exchange Act Documents by Reference.

     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 Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
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) Request for Acceleration of Effective Date.

    
     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 informed 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 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 of 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) Trust Indenture Application.

     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 ("Act") in accordance with the
rules and regulations prescribed by the Commission under Section 305(b)(2) of
the Act.

certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing this Registration Statement on Form S-3 and has duly
caused this Registration Statement to be signed on its behalf by the
undersigned, thereunto duly authorized, in the City of Coudersport, Commonwealth
of Pennsylvania, on the 14th day of July, 1998.

<PAGE>

     Every certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture shall include:

opinion has read such covenant or condition and the definitions herein relating

waiver or other action provided by this Indenture to be given or taken by
Holders 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; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 6.1) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

            (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 manner which the Trustee deems sufficient.

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

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

            (e) If the Company shall solicit from the Holders any request,
demand, authorization, direction, notice, consent, waiver or other Act, the
Company may, at its option, by 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. 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,

                                      -10-
<PAGE>
 
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 six months after the record
date.

(S) 1.5.    Notices, Etc., to 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,

            (a) 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 and received by the Trustee at its Corporate Trust Office,
Attention: Corporate Trust Administration, or

            (b) 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, attention: Secretary, or at any other address previously furnished in
writing to the Trustee by the Company.

(S) 1.6.    Notice to Holders; Waiver.

     Where this Indenture or any Security provides for notice to Holders of any
event, such notice shall be deemed sufficiently given (unless otherwise herein
or in such Security expressly provided) if in writing and mailed, first-class
postage prepaid, to each 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 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 or the
validity of the proceedings to which such notice relates.  Where this Indenture
or any Security 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.

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

required or permitted under this Indenture shall be in the English language,

     If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required to be included in this Indenture by any of
the provisions of the Trust Indenture Act, such required provision shall
control.  If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act that may be so modified or excluded, the latter
provision shall be deemed to apply to this Indenture as so modified or shall be
excluded, as the case may be.

(S) 1.8.    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.

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

(S) 1.13.   Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date or Stated

then (notwithstanding any other provision of this Indenture or of the
Securities) payment of interest or principal (and premium, if any) need not be
made at such Place of Payment on

                                      -12-

such date, but may be made on the next succeeding Business Day or on such other
day as may be set out in the Officer's Certificate pursuant to Section 3.1 at
such Place of Payment with the same force and effect as if made on the Interest
Payment Date or Redemption Date, or at the Stated Maturity, provided that no
interest shall accrue for the period from and after such Interest Payment Date,
Redemption Date or Stated Maturity, as the case may be.

(S) 1.14.   No Recourse Against Others.

     A director, officer, employee or stockholder, as such, of the Company shall
not have any liability for any obligations of the Company under the Securities
or this Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation.  Each Security holder, by accepting a Security,
waives and releases all such liability.  Such waivers and releases are part of
the consideration for the issuance of the Securities.

of Securities of this series.) (Securities of this series acquired or redeemed
by the Company otherwise than through (mandatory) sinking fund payments may be

     (In the event of redemption of this Security in part only a new Security or

     (If the Security is not an Original Issue Discount Security, insert -- If

amount.) Upon payment (i) of the amount of principal so declared due and payable
and (ii) of interest on any overdue principal and overdue interest (in each case

and interest, if any, on the Securities of this series shall terminate.

     This Security is a senior unsecured obligation of the Company and will rank
pari passu in right of payment with all other senior unsecured obligations of
the Company.

     This Security is subject to Defeasance as described in the Indenture.  The
Indenture may be modified by the Company and the Trustee without consent of any
Holder with respect to certain matters as described in the Indenture.  In
addition, the Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Securities at
the time Outstanding of each series to be affected.  The Indenture also contains
provisions permitting the Holders of a majority in principal amount of the
Securities of each series at the time Outstanding, on behalf of the Holders of
all Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences.  Any such consent or waiver by the Holder of this Security
shall bind such Holder and all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange hereof
or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Security.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and

                                      -18-
<PAGE>
 
unconditional, to pay the principal of, and premium, if any, and interest on
this Security at the times, place and rate, and in the coin or currency, herein
prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Company in any place where the principal of (and premium, if any)
and interest on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this series,
of authorized denominations and for the same Stated Maturity and aggregate
principal amount, will be issued to the designated transferee or transferees.

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

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

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

     The Indenture imposes certain limitations on the ability of the Company to,
among other things, merge or consolidate with any other Person or sell, assign,
transfer or lease all or substantially all of its properties or assets (If other
covenants are applicable pursuant to the provisions of Section 3.1, insert
here).  All such covenants and limitations are subject to a number of important
qualifications and exceptions.  The Company must report periodically to the
Trustee on compliance with the covenants in the Indenture.

     A director, officer, employee or stockholder, as such, of the Company shall
not have any liability for any obligations of the Company under this Security or
the Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation.  Each Holder, by accepting a Security, waives and
releases all such liability.  The waiver and release are part of the
consideration for the issuance of this Security.

     (If applicable, insert -- Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures ("CUSIP"), the Company
has caused CUSIP numbers to be printed on the Securities of this series as a
convenience to the Holders of the Securities of this series.  No representation
is made as to the

(S) 2.5.    Securities in Global Form.

     If Securities of a series are issuable in global form, as contemplated by
Section 3.1, then, notwithstanding the provisions of Section 3.2, 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 from time to time endorsed thereon and that the
aggregate amount of Outstanding Securities represented thereby may from time to
time be reduced to reflect exchanges.  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 in such manner and upon
instructions 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 3.3 or
Section 3.4.  Subject to the provisions of Section 3.3 and, if applicable,
Section 3.4, the Trustee shall deliver and redeliver any Security in permanent
global form in the manner and upon instructions given by the Person or Persons
specified therein or in the applicable Company Order.  If a Company Order
pursuant to Section 3.3 or 3.4 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 1.2 and need not be accompanied by an Opinion of Counsel.

     The provisions of Section 3.9 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 1.2 and
need not be accompanied by an Opinion of Counsel) with regard to the reduction
in the principal amount of Securities represented thereby.

     Notwithstanding the provisions of Sections 2.1 and 3.7, unless otherwise
specified as contemplated by Section 3.1, payment of principal of, premium, if
any, and interest on any Security in permanent global form shall be made to the
Person or Persons specified therein.

     Notwithstanding the provisions of Section 3.8 and except as provided in the
preceding paragraph, the Company, the Trustee and any agent of the Company and
the Trustee shall treat a Person as the Holder of such principal amount of
Outstanding Securities represented by a permanent global Security as shall be
specified in a written statement of the Holder of such permanent global
Security.

(S) 2.6.    CUSIP Number.

     The Company in issuing Securities of any series may use a "CUSIP" number,
and, if so, the Trustee may use the CUSIP number in notices of redemption or
exchange as a

                                      -22-
<PAGE>
 
convenience to Holders of such series; provided, that any such notice may state
that no representation is made as to the correctness or accuracy of the CUSIP
number printed on the notice or on the Securities of such series, and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Company will promptly notify the Trustee of any
change in the CUSIP number of any series of Securities.

(S) 2.7.    Form of Legend for the Securities in Global Form.

     Any Security in global form authenticated and delivered hereunder shall
bear a legend in substantially the following form:

     "This Security is in global form within the meaning of the Indenture
hereinafter referred to and is registered in the name of a Common Depositary or
a U.S. Depositary.  Unless and until it is exchanged in whole or in part for
Securities in certificated form, this Security may not be transferred except as
a whole by the Common Depositary or a U.S. Depositary or by a nominee of the
Common Depositary or a nominee of the U.S. Depositary as the case may be."

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series 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 make such Securities available for
delivery.  If the form or terms of the Securities of the series have been
established in or pursuant to one or more Board Resolutions as permitted by
Sections 2.1 and 3.1, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive, and (subject to Sections 315(a)
through (d) of the Trust Indenture Act) shall be fully protected in relying
upon, an Opinion of Counsel stating,

            (a) if the form of such Securities has been established by or
pursuant to Board Resolution as permitted by Section 2.1, that such form has
been established in conformity with the provisions of this Indenture;
 
            (b) if the terms of such Securities have been established by or
pursuant to Board Resolution as permitted by Section 3.1, that such terms have
been established in conformity with the provisions of this Indenture;

                                      -26-
<PAGE>
 
            (c) that such Securities, when authenticated and delivered by the
Trustee and issued by the Company in the manner and subject to any conditions
specified in such Opinion of Counsel, will constitute valid and legally binding
obligations of the Company, enforceable in accordance with their terms, except
to the extent enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium and other similar laws affecting the
enforcement of creditors' rights generally and by the effect of general
principles of equity (regardless of whether enforceability is considered in a
proceeding in equity or at law); and
 
            (d) that no consent, approval, authorization, order, registration or
qualification of or with any court or any governmental agency or body having
jurisdiction over the Company is required for the execution and delivery of such
Securities by the Company, except such as have been obtained (except that no
opinion need be expressed as to state securities or Blue Sky laws).

     If such form or terms have been so established, 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 or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee, or in the written opinion of
counsel to the Trustee (which counsel may be an employee of the Trustee) such
authentication may not lawfully be made or would involve the Trustee in personal
liability.

     Notwithstanding the provisions of Section 3.1 and of the immediately
preceding paragraph, if all Securities of a series are not to be originally
issued at one time, it shall not be necessary to deliver the Officer's
Certificate otherwise required pursuant to Section 3.1 or the Company Order and
Opinion of Counsel otherwise required pursuant to the immediately preceding
paragraph at or prior to the time of authentication of each security of such
series if such documents are delivered at or prior to the authentication upon
original issuance of the first security of such series to be issued.

     If the Company shall establish pursuant to Section 3.1 that the Securities
of a series are to be issued in the form of one or more global Securities, then
the Company shall execute and the Trustee shall, in accordance with this Section
and the Company Order with respect to the authentication and delivery of such
series, authenticate and deliver one or more global Securities that (i) shall be
in an aggregate amount equal to the aggregate principal amount specified in such
Company Order, (ii) shall be registered in the name of the Common Depositary or
U.S. Depositary, as the case may be, therefor or its nominee, and (iii) shall be
made available for delivery by the Trustee to such depositary or pursuant to
such depositary's instruction.

     Each depositary designated pursuant to Section 3.1 must, at the time of its
designation and at all times while it serves as depositary, be a clearing agency
registered under the Exchange Act and any other applicable statute or
regulation.

                                      -27-
<PAGE>
 
     Unless otherwise provided for in the form of security, each security shall
be dated the date of its authentication.

     No security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, 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.

(S) 3.4.    Temporary Securities.

     Pending the preparation of definitive Securities of any series, the Company
may execute, and upon Company Order the Trustee shall authenticate and make
available for delivery, 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 and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

     In the case of Securities of any series, such temporary Securities may be
in global form, representing all or a portion of the Outstanding Securities of
such series.

     Except in the case of temporary Securities in global form (which shall be
exchanged in accordance with the provisions of Section 3.5), 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, the Company shall execute and the Trustee shall authenticate and make
available for delivery in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor.  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.

     If temporary Securities of any series are issued in global form, any such
temporary global Security shall, unless otherwise provided therein, be delivered
to the office of a depositary or common depositary (the "COMMON DEPOSITARY") for
credit to the respective accounts of the beneficial owners of such Securities
(or to such other accounts as they may direct).

                                      -28-

(S) 3.5.    Registration, Registration of Transfer and Exchange.

     The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of registration of transfers of Securities.  The
Trustee is hereby appointed "Security Registrar" for the purpose of registering
Securities and transfers of Securities as herein provided.

     Upon surrender for registration of transfer of any security of any series
at the office or agency of the Company in Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and make available for
delivery, in the name of the designated transferee or transferees, one or more
new Securities of the same series, of any authorized denominations and of a like
aggregate principal amount and Stated Maturity.

     At the option of the Holder, Securities of any series may be exchanged for
other Securities of the same series, of any authorized denominations and of a
like aggregate principal amount and Stated Maturity, upon surrender of the
Securities to be exchanged at such office or agency.  Whenever any Securities
are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and make available for delivery, the Securities which the
Holder making the exchange is entitled to receive.

     Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 3.1, any permanent global security shall be exchangeable
only as provided in this paragraph.  If the beneficial owners of interests in a
permanent global security are entitled to exchange such interests for Securities
of such series and of like tenor and principal amount of another authorized form
and denomination, as specified and as subject to the conditions contemplated by
Section 3.1, then without unnecessary delay but in any event not later than the
earliest date on which such interests may be so exchanged, the Company shall
deliver to the Trustee definitive Securities of that series in aggregate
principal amount equal to the principal amount of such permanent global
security, executed by the Company.  On or after the earliest date on which such
interests may be so exchanged, such permanent global Securities shall be
surrendered from time to time by the Common Depositary or the U.S. Depositary,
as the case may be, and in accordance with instructions given to the Trustee and
the Common Depositary or the U.S. Depositary, as the case may be (which
instructions shall be in writing but need not comply with Section 1.2 or be
accompanied by an Opinion of Counsel), as shall be specified in the Company
Order with respect thereto to the Trustee, as the Company's agent for such
purpose, to be exchanged, in whole or in part, for definitive Securities of the
same series without charge.  The Trustee shall authenticate and make available
for delivery, in exchange for each portion of such surrendered permanent global
security, a like aggregate principal amount of definitive Securities of the same
series of authorized denominations and of like tenor as the portion of such
permanent global security to be

                                      -29-
<PAGE>
 
exchanged which shall be in the form of the Securities of such series; provided,
however, that no such exchanges may occur during a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of Securities of that series selected for redemption under Section
11.3 and ending at the close of business on the day of such mailing. Promptly
following any such exchange in part, such permanent global Security shall be
returned by the Trustee to the Common Depositary or the U.S. Depositary, as the
case may be, or such other Common Depositary or U.S. Depositary referred to
above in accordance with the written instructions of the Company referred to
above. If a Security in the form specified for such series 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
interest or Defaulted Interest, as the case may be, such interest or Defaulted
Interest will not be payable on such Interest Payment Date or proposed date for
payment, as the case may be, in respect of such security in the form specified
for such series, 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 obligation, 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 Security presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to
the Company and the Security Registrar duly executed, by the Holder thereof or
his attorney duly authorized in writing.

Unless otherwise provided in the Securities to be transferred or exchanged, 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 3.4, 9.6 or 11.7 not involving any transfer.

     The Company shall not be required (i) to issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 11.3 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any security so selected for

                                      -30-
<PAGE>
 
redemption in whole or in part, except the unredeemed portion of any security
being redeemed in part.

(S) 3.6.    Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security 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 notice to the
Company or the Trustee that such Security 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, a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

     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 issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security 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 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.

(S) 3.7.    Payment of Interest; Interest Rights Preserved.

     Interest on any Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid at the Place of Payment
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, except that at the option of the Company payment may be made
(i) except in the case of a global Security by

                                      -31-
<PAGE>
 
check mailed to the address of the Person entitled thereto as such address
appears in the Securities Registrar or (ii) by transfer to an account maintained
by the Person entitled thereto as specified in the Securities Registrar provided
that proper transfer instructions have been received by the Regular Record Date.

     Any interest on any Security of any series which 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 Holder
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 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 Security of such series
and the date of the proposed payment, and at the same time the Company shall
deposit with the Trustee an amount of money 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 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 Section
3.7 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 Securities of such series
at his 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 so mailed,
such Defaulted Interest shall be paid to the Persons in whose names the
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).
 
            (2) The Company may make payment of any Defaulted Interest on the
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 to the Trustee of the proposed payment pursuant to this Section
3.7, such manner of payment shall be deemed practicable by the Trustee.

     Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other

                                      -32-
<PAGE>
 
Security shall carry the rights to interest accrued and unpaid, and to accrue,
which were carried by such other Security.

(S) 3.8.    Persons Deemed Owners.

     Prior to due presentment of a 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 Security is registered as the owner of such Security
for the purpose of receiving payment of principal of (and premium, if any) and
(subject to Section 3.7) interest on such Security and for all other purposes
whatsoever, whether or not such 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.

     None of the Company, the Trustee or any agent of the Company or the Trustee
shall have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interest of a
Security in global form, or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interest.  Notwithstanding the
foregoing, with respect to any Security in global form, nothing herein shall
prevent the Company or 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 U.S. Depositary or Common Depositary (or its nominee), as a
Holder, with respect to such Security in global form or impair, as between such
U.S. Depositary or Common Depositary and owners of beneficial interests in such
Security in global form, the operation of customary practices governing the
exercise of the right of such U.S. Depositary or Common Depositary (or its
nominee) as holder of such Security in global form.

(S) 3.9.    Cancellation.

     All Securities surrendered for payment, redemption, 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 shall be promptly cancelled 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 all Securities so delivered shall be promptly cancelled by the
Trustee.  No Securities shall be authenticated in lieu of or in exchange for any
Securities cancelled as provided in this Section, except as expressly permitted
by this Indenture.  All cancelled Securities shall be held by the Trustee and
may be destroyed (and, if so destroyed, certification of their destruction shall
be delivered to the Company upon its request, unless, by a Company Order, the
Company shall direct that cancelled Securities be returned to it).

(S) 3.10.   Computation of Interest.

     Except as otherwise specified as contemplated by Section 3.1 for 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 4

                           SATISFACTION AND DISCHARGE

(S) 4.1.    Satisfaction and Discharge of Indenture.

     This Indenture shall cease to be of further effect (except as to any
surviving rights of registration of transfer or exchange of Securities herein
expressly provided for or in the form of Security for such series), when the
Trustee, upon Company Request and at the expense of the Company, shall execute
proper instruments acknowledging satisfaction and discharge of this Indenture,
when

            (1) either
 
            (A) all Securities theretofore authenticated and delivered (other
than (i) Securities which have been destroyed, lost or stolen and which have
been replaced or paid as provided in Section 3.6 and (ii) Securities 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 10.9) have been delivered to the Trustee for
cancellation; or
 
            (B) all such Securities 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) are to be called for redemption within one 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,

and the Company, in the case of (i), (ii) or (iii) above, has deposited with the
Trustee as trust funds in trust for the purpose an amount sufficient to pay and
discharge the entire indebtedness on such Securities not theretofore delivered
to the Trustee for cancellation, for principal (and premium, if any) and
interest 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;

                                      -34-
<PAGE>
 
            (2) the Company has paid or caused to be paid all other sums payable
hereunder by the Company; and
 
            (3) the Company has delivered to the Trustee an Officer's
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for herein relating to the satisfaction and discharge of this
Indenture have been complied with.

     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7, the obligations of
the Company to any Authenticating Agent under Section 6.14 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee under Section 4.2 and the last
paragraph of Section 10.9 shall survive.

(S) 4.2.    Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 10.9, all money
deposited with the Trustee pursuant to Section 4.1 shall be held in trust and
applied by it, in accordance with the provisions of the Securities 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, if
any) and interest for whose payment such money has been deposited with or
received by the Trustee.

                                   ARTICLE 5

                                    REMEDIES

(S) 5.1.    Events of Default.

     "EVENT OF DEFAULT," wherever used herein with respect to Securities of any
series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or to 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):

            (1) the Company defaults in the payment of interest or any sinking
fund payment on any Security of that series when such interest becomes due and
payable and the default continues for a period of 60 days; provided, however,
that if the Company is permitted by the terms of the Securities of the
applicable series to defer the payment in question, the date on which such
payment is due and payable shall be the date on which the Company is required to
make payment following such deferral, if such deferral has been elected pursuant
to the terms of the Securities; or
 
            (2) the Company defaults in the payment of the principal of (or
premium, if any, on) any Security of that series when the same becomes due and
payable at Maturity, upon redemption (including redemptions under Article 11),
by declaration or

                                      -35-
<PAGE>
 
otherwise; provided, however, that if the Company is permitted by the terms of
the Securities of the applicable series to defer the payment in question, the
date on which such payment is due and payable shall be the date on which the
Company is required to make payment following such deferral, if such deferral
has been elected pursuant to the terms of the Securities; or

            (3) the Company fails to observe or perform in any material respect
any of its other covenants, warranties or agreements in the Securities of that
series or in this Indenture (other than a covenant, agreement or warranty a
default in whose performance or whose breach is elsewhere in this Section
specifically dealt with or which has expressly been included in this Indenture
solely for the benefit of series of Securities other than that series), and the
failure to observe or perform continues for the period and after the notice
specified in the last paragraph of this Section; or

            (4) any event of default, as defined in any other indenture,
mortgage, or instrument under which there may be issued, or by which there may
be secured or evidenced, any Indebtedness of the Company (whether such
Indebtedness now exists or shall hereafter be created or incurred) shall occur
and shall consist of default in the payment of such Indebtedness at the maturity
thereof (after giving effect to any applicable grace period) or shall result in
Indebtedness becoming or being declared due and payable prior to the date on
which it would otherwise become due and payable, and such default in payment is
not cured or such acceleration shall not be rescinded or annulled within 30 days
after written notice to the Company from the Trustee or to the Company and to
the Trustee from the Holders of at least 25% in aggregate principal amount of
the Securities of that series at the time outstanding; provided that it shall
not be an Event of Default if the principal amount of Indebtedness (other than
Indebtedness represented by Securities issued pursuant to this Indenture) which
is not paid at maturity or the maturity of which is accelerated is less than or
equal to $25 million provided further that if, prior to a declaration of
acceleration of the maturity of the Securities of that series or the entry of
judgment in favor of the Trustee in a suit pursuant to Section 5.3, such default
shall be remedied or cured by the Company or waived by the holders of such
Indebtedness, then the Event of Default hereunder by reason thereof shall be
deemed likewise to have been thereupon remedied, cured or waived without further
action upon the part of either the Trustee or any of the Holders of the
Securities of that series, and provided further, that, subject to Sections 6.1
and 6.2, the Trustee shall not be charged with knowledge of any such default
unless written notice of such default shall have been given to the Trustee by
the Company, by a holder or an agent of a holder of any such Indebtedness, by
the trustee then acting under any indenture or other instrument under which such
default shall have occurred, or by the Holders of at least five percent in
aggregate principal amount of the Securities of that series at the time
Outstanding; or
 
            (5) the Company pursuant to or within the meaning of any Bankruptcy
Law (A) commences a voluntary case or proceeding under any Bankruptcy Law with
respect to itself, (B) consents to the entry of a judgment, decree or order for
relief against it in an involuntary case or proceeding under any Bankruptcy Law,
(C) consents to or

                                      -36-

it, (D) applies for, consents to or acquiesces in the appointment of or taking
possession by a Custodian of the Company or for any material part of its
property, (E) makes a general assignment for the benefit of its creditors or (F)
takes any corporate action in furtherance of or to facilitate, conditionally or
otherwise, any of the foregoing; or
 
            (6) (i) a court of competent jurisdiction enters a judgment, decree
or order for relief in respect of the Company in an involuntary case or
proceeding under any Bankruptcy Law which shall (A) approve as properly filed a
petition seeking reorganization, arrangement, adjustment or composition in
respect of the Company, (B) appoint a Custodian of the Company or for any
material part of its property, or (C) order the winding-up or liquidation of its
affairs, and such judgment, decree or order shall remain unstayed and in effect
for a period of 60 consecutive days; or (ii) any bankruptcy or insolvency
petition or application is filed, or any bankruptcy or insolvency proceeding is
commenced against the Company and such petition, application or proceeding is
not dismissed within 60 days; or (iii) a warrant of attachment is issued against
any material portion of the property of the Company which is not released within
60 days of service; or
 
            (7) any other Event of Default provided with respect to Securities
of that series.

     A Default under clause (3) above is not an Event of Default until the
Trustee or the Holders of at least 25% in aggregate principal amount of the
Outstanding Securities of that series notify the Company of the Default and the
Company does not cure the Default within 90 days after receipt of the notice.
The notice must specify the Default, demand that it be remedied and state that
the notice is a "Notice of Default." When a Default under clause (3) above is
cured within such 90-day period, it ceases.

(S) 5.2.    Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default with respect to Securities of any series (other than
an Event of Default specified in clause (5) or (6) of Section 5.1) occurs and is
continuing, the Trustee by notice in writing to the Company, or the Holders of
at least 25% in aggregate principal amount of the Outstanding Securities of that
series by notice in writing to the Company and the Trustee, may declare the
unpaid principal of and accrued interest to the date of acceleration (or, if the
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of that series) on all
the Outstanding Securities of that series to be due and payable immediately and,
upon any such declaration, the Outstanding Securities of that series (or
specified principal amount) shall become and be immediately due and payable.

     If an Event of Default specified in clause (5) or (6) of Section 5.1
occurs, all unpaid principal of and accrued interest on the Outstanding
Securities of that series (or specified principal amount) shall ipso facto
become and be immediately due and payable

                                      -37-
<PAGE>
 
without any declaration or other act on the part of the Trustee or any Holder of
any Security of that series.

     Upon payment of all such principal and interest, all of the Company's
obligations under the Securities of that series and (upon payment of the
Securities of all series) this Indenture shall terminate, except obligations
under Section 6.7.

     The Holders of a majority in principal amount of the Outstanding Securities
of that series by notice to the Trustee may rescind an acceleration and its
consequences if (i) all existing Events of Default, other than the nonpayment of
the principal and interest of the Securities of that series that has become due
solely by such declaration of acceleration, have been cured or waived, (ii) to
the extent the payment of such interest is lawful, interest on overdue
installments of interest and overdue principal that has become due otherwise
than by such declaration of acceleration have been paid, (iii) the rescission
would not conflict with any judgment or decree of a court of competent
jurisdiction and (iv) all payments due to the Trustee and any predecessor
Trustee under Section 6.7 have been made.

(S) 5.3.    Collection of Indebtedness and Suits for Enforcement by Trustee.
 
     The Company covenants that if:

            (1) default is made in the payment of any interest on any Security
of any series when such interest 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,
if any, on) any Security of any series at the Maturity thereof, the Company
will, upon demand of the Trustee, pay to it, for the benefit of the Holders of
such Securities, the whole amount then due and payable on such Securities for
principal (and premium, if any) and interest and, to the extent that payment of
such interest shall be legally enforceable, interest on any overdue principal
(and premium, if any) and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the reasonable 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, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities 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, wherever
situated.

                                      -38-
<PAGE>
 
     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 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 secure any other proper remedy.

(S) 5.4.    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
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 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 of principal (and
premium, if any) and interest 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 agent and
counsel) and of the Holders allowed in such judicial proceedings, 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 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 it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 6.7.

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

(S) 5.5.    Trustee May Enforce Claims Without Possession of Securities.

     All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding

                                      -39-
<PAGE>
 
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 in respect of which such judgment has been recovered.

(S) 5.6.    Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article in respect of
the Securities of any series 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, if any) or interest, upon
presentation of the Securities in respect of which moneys have been collected
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 under Section 6.7
applicable to such series;

     Second:  To the payment of the amounts then due and unpaid for principal of
(and premium, if any) and interest on the Securities of such series 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 amounts due and
payable on such Securities of such series for principal (and premium, if any)
and interest, respectively; and

     Third:  To the Company.

     The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 5.6.  At least fifteen (15) days before such
record date, the Trustee shall mail to each Holder and the Company a notice that
states the record date, the payment date and the amount to be paid.

(S) 5.7.    Limitation on Suits.

     No Holder of any Security of any series 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;

                                      -40-
<PAGE>
 
            (3) such Holder or Holders have offered to the Trustee reasonable
indemnity 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 of a majority in
principal amount of the Outstanding Securities of that series; it being
understood and intended that no one or more of Holders of Securities of any
series 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 Holders of Securities of the affected series.

(S) 5.8.    Unconditional Right of Holders to Receive Principal, Premium and
            Interest.

     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of (and premium, if any) and (subject to Section 3.7)
interest on such Security on the Stated Maturity or Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.

(S) 5.9.    Restoration of Rights and Remedies.

     If the Trustee or any Holder 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, subject to any determination in
such proceeding, the Company, the Trustee and the Holders shall 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.

(S) 5.10.   Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
3.6, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders 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

                                      -41-
<PAGE>
 
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.

(S) 5.11.   Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Securities 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 an
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, as the case may
be.

(S) 5.12.   Control by Holders.

     The Holders of 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) subject to Section 6.1, the Trustee need not take any action
which might involve the Trustee in personal liability or be unduly prejudicial
to the Holders not joining therein.
 
(S) 5.13.   Waiver of Past Defaults.

     The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may by written notice to the Trustee on
behalf of the Holders of all the Securities of such series waive any Default or
Event of Default with respect to such series and its consequences, except a
Default or Event of Default

            (1) in respect of the payment of the principal of (or premium, if
any) or interest on any Security of such series, or
 
            (2) in respect of a covenant or other 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.
 
            (3) Upon any such waiver, such Default or Event of Default shall
cease to exist and shall be deemed to have been cured, for every purpose of this
Indenture and the Securities of such series; but no such waiver shall extend to
any subsequent or other Default or Event of Default or impair any right
consequent thereon.

(S) 5.14.   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,
suffered 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
Company, to any suit instituted by 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 of any series, or to any suit instituted by
any Holder for the enforcement of the payment of the principal of (or premium,
if any) or interest on any Security on or after the Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).

                                   ARTICLE 6

                                  THE TRUSTEE

(S) 6.1.    Certain Duties and Responsibilities of the Trustee.
 
            (a) Except during the continuance of an Event of Default, the
Trustee's duties and responsibilities under this Indenture shall be governed by
Section 3.15(a) of the Trust Indenture Act.
 
            (b) In case an Event of Default has occurred and is continuing, and
is known to the Trustee, the Trustee shall exercise the rights and powers vested
in it by this Indenture, and shall use the same degree of care and skill in
their exercise, as a prudent man would exercise or use under the circumstances
in the conduct of his own affairs.
 
            (c) None of the provisions of Section 315(d) of the Trust Indenture
Act shall be excluded from this Indenture.
 
(S) 6.2.    Notice of Defaults.

     Within 30 days after the occurrence of any Default or Event of Default with
respect to the Securities of any series, the Trustee shall give to all Holders
of Securities of such series, as their names and addresses appear in the
Security Register, notice of such Default or Event of Default known to the
Trustee, unless such Default or Event of Default shall have been cured or
waived; provided, however, that, except in the case of a Default or Event of
Default in the payment of the principal of (or premium, if any) or interest on
any Security of such series or in the payment of any sinking fund installment
with respect to Securities of such series, the Trustee shall be protected in
withholding such notice if

                                      -43-
<PAGE>
 
and so long as the board of directors, the executive committee or directors or
Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the interest of the Holders of Securities of such series.

(S) 6.3.    Certain Rights of Trustee.
 
     Subject to the provisions of the Trust Indenture Act:

            (a) the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document believed by it
to be genuine and to have been signed or presented by the proper party or
parties;
 
            (b) any request or direction of the Company mentioned herein shall
be sufficiently evidenced by a Company Request or Company Order and any
resolution of the Board of Directors may be sufficiently evidenced by a Board
Resolution;
 
            (c) 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 Officer's Certificate;
 
            (d) the Trustee may consult with counsel and the written 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;
 
            (e) 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 pursuant to this Indenture, unless such Holders shall have
offered to the Trustee security or indemnity to its reasonable satisfaction
against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction;
 
            (f) prior to the occurrence of an Event of Default with respect to
the Securities of any series and after the curing or waiving of all such Events
of Default which may have occurred, 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, approval or other paper or document, or the books and records of the
Company, unless requested in writing to do so by the Holders of a majority in
principal amount of the Outstanding Securities of any series; provided, however,
that if the payment within a reasonable time to the Trustee of the costs,
expenses or liabilities likely to be incurred by it in the making of such
investigation is not, in the opinion of the Trustee, reasonably assured to the
Trustee by the security afforded to it by the terms of this Indenture, the
Trustee may require reasonable indemnity against such costs, expenses or
liabilities as a condition to so proceeding; the

                                      -44-
<PAGE>
 
reasonable expense of every such investigation shall be paid by the Company or,
if paid by the Trustee, shall be repaid by the Company upon demand;
 
            (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder; and
 
            (h) 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 its rights or powers, if it shall
have reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

(S) 6.4.    Not Responsible for Recitals or Issuance of Securities.

     The recitals herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee or any Authenticating Agent assumes no responsibility for their
correctness.  The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities.  Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

(S) 6.5.    May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
6.8 and 6.13, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

(S) 6.6.    Money Held in Trust.

     Money held by the Trustee in trust hereunder (including amounts held by the
Trustee as Paying Agent) need not be segregated from other funds except to the
extent required by law.  The Trustee shall be under no liability for interest on
any money received by it hereunder except as otherwise agreed upon in writing
with the Company.

(S) 6.7.    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 (which compensation shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust);
 

                                      -45-
<PAGE>
 
            (2) except as otherwise expressly provided herein, to reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any provision of this
Indenture (including the reasonable compensation and the expenses and
disbursements of its agents and counsel), except any such expense, disbursement
or advance as may be attributable to its negligence or bad faith; and
 
            (3) to indemnify the Trustee for, and to hold it harmless against,
any loss, liability, damage, claim or expense, including taxes (other than taxes
based upon or determined or measured by the income of the Trustee), incurred
without gross negligence or bad faith on its part, arising out of or in
connection with the acceptance or administration of the trust or trusts
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.

     When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 5.1(5) or Section 5.1(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

     The provisions of this Section 6.7 shall survive this Indenture and the
resignation or removal of any Trustee hereunder.

(S) 6.8.    Disqualification; Conflicting Interests.

     The Trustee shall be disqualified only where such disqualification is
required by Section 310(b) of the Trust Indenture Act.  Nothing shall prevent
the Trustee from filing with the Commission the application referred to in the
second to last paragraph of Section 310(b) of the Trust Indenture Act.

(S) 6.9.    Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee hereunder which shall be eligible to
act as Trustee under Section 310(a)(1) of the Trust Indenture Act having a
combined capital and surplus of at least $50,000,000 subject to supervision or
examination by federal or State authority.  If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of said supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published.  Neither the Company nor any Person directly or
indirectly controlling, controlled by, or under common control with the Company
may serve as Trustee.  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.

                                      -46-
<PAGE>
 
(S) 6.10.   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 6.11.
 
            (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 the instrument of acceptance by a successor Trustee required by
Section 6.11 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 with
respect to the Securities of such series.
 
            (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 Section 310(b) of the
Trust Indenture Act after written request therefor by the Company or by any
Holder 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 6.9 and
shall fail to resign after written request here for by the Company or by any
such 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 a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 315(e) of the
Trust Indenture Act, any Holder 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 a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect

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) and
shall comply with the applicable requirements of Section 6.11. 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 in accordance with the applicable requirements of Section
6.11, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the Company with
respect to such Securities. If no successor Trustee with respect to the
Securities of any series shall have been so appointed by the Company or the
Holders and accepted appointment in the manner required by Section 6.11, any
Holder 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 the 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
by mailing written notice of such event by first-class mail, postage prepaid, to
all Holders of Securities of such series as their names and addresses appear in
the security Register. 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.

(S) 6.11.   Acceptance of Appointment by Successor or Additional Trustees.
 
            (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed 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 the 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.
 
            (b) In case of the appointment hereunder of a Trustee or a successor
with respect to the Securities of one or more (but not all) series, the Company,
any retiring Trustee and each Trustee or a successor Trustee with respect to the
Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each Trustee or a 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 Trustee
or a successor Trustee all the rights, powers, trusts and duties of

                                      -48-
<PAGE>
 
any retiring Trustee with respect to the Securities of that or those series to
which the appointment of such Trustee or a successor Trustee relates, (2) if any
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 any retiring Trustee with respect to
the Securities of that or those series as to which any retiring Trustee is not
retiring shall continue to be vested in any 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 Trustee or a successor Trustee, without
any further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of any retiring Trustee with respect to the Securities
of that or those series to which the appointment of such Trustee or a successor
Trustee relates; but, on request of the Company or any Trustee or a successor
Trustee, any such retiring Trustee shall duly assign, transfer and deliver to
such Trustee or a successor Trustee all property and money held by any such
retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of any such Trustee or 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 the Trust Indenture Act.
 
(S) 6.12.   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 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 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 so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

(S) 6.13.   Preferential Collection of Claims Against Company.

     The Trustee shall comply with Section 311(a) of the Trust Indenture Act,
excluding any creditor relationship listed in Section 311(b) of the Trust
Indenture Act.  A Trustee who has resigned or been removed shall be subject to
Section 311(a) of the Trust Indenture Act to the extent indicated therein.

(S) 6.14.   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, and subject to the
direction of, the Trustee to authenticate Securities of such series issued upon
exchange, registration of transfer or partial redemption thereof or pursuant to
Section 3.6, and Securities so authenticated shall be entitled to the benefits
of this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder.  Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent.  Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $5,000,000 and
subject to supervision or examination by federal or State authority.  If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said 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.  If 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 any further
act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a

                                      -50-
<PAGE>
 
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 may
appoint a successor Authenticating Agent which shall be acceptable to the
Company and shall mail written notice of such appointment by first-class mail,
postage prepaid, to all Holders of Securities of the series with respect to
which such Authenticating Agent will serve, as their names and addresses appear
in the security Register. 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. 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 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 lieu
of the Trustee's certificate of authentication, an alternate certificate of
authentication in the following form:

          Form of Authenticating Agent's
          Certificate of Authentication

Dated: 
       ____________________

 

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

               HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

(S) 7.1.    Company to Furnish Trustee Names and Addresses of Holders.
 
     The Company will furnish or cause to be furnished to the Trustee:

            (a) semi-annually, not later than January 1 and July 1 in each year,
a list, in such form as the Trustee may reasonably require, of the names and
addresses of the Holders as of the preceding December 15 or June 15, as the case
may be; 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 list shall be required to be furnished; provided,
however, that so long as the Trustee is the Security Registrar, no such list
shall be required to be furnished.

(S) 7.2.    Preservation of Information; Communications to Holders.
 
            (a) The Trustee shall preserve, in as current a form as is
reasonably practicable, the names and addresses of Holders contained in the most
recent list furnished to the Trustee as provided in Section 7.1 and the names
and addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 7.1 upon receipt of a new list so furnished.
 
            (b) If three or more Holders (herein referred to as "applicants")
apply in writing to the Trustee, and furnish to the Trustee reasonable proof
that each such applicant has owned a Security for a period of at least six
months preceding the date of such application, and such application states that
the applicants desire to communicate with other Holders with respect to their
rights under this Indenture or under the Securities and is accompanied by a copy
of the form of proxy or other communication which such applicants propose to
transmit then the Trustee shall, within five Business Days after the receipt of
such application, at its election, either
 
            (i) afford such applicants access to the information preserved at
the time by the Trustee in accordance with Section 7.2(a); or
 
            (ii) inform such applicants as to the approximate number of Holders
whose names and addresses appear in the information preserved at the time by the
Trustee in accordance with Section 7.2(a), and as to the approximate cost of
mailing to such Holders the form of proxy or other communication, if any,
specified in such application.

                                      -52-
<PAGE>
 
     If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder whose name and address appears in the information preserved
at the time by the Trustee in accordance with Section 7.2(a) a copy of the form
of proxy or other communication which is specified in such request, with
reasonable promptness after a tender to the Trustee of the material to be mailed
and of payment, or provision for the payment, of the reasonable expenses of
mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interest of the Holders
or would be in violation of applicable law.  Such written statement shall
specify the basis of such opinion.  If the Commission, after opportunity for a
hearing upon the objections specified in the written statement so filed, shall
enter an order refusing to sustain any of such objections or if, after the entry
of an order sustaining one or more of such objections, the Commission shall
find, after notice and opportunity for hearing, that all objections so sustained
have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all such Holders with reasonable promptness after the
entry of such order and the renewal of such tender; otherwise the Trustee shall
be relieved of any obligation or duty to such applicants respecting their
application.

            (c) Every Holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
nor any agent of either of them shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the Holders
in accordance with Section 702(b), 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 Section 7.2(b).

provided in Section 313(c) of the Trust Indenture Act, a brief report dated as
of May 15, if required by and in compliance with Section 313(a) of the Trust
Indenture Act.
 
            (b) A copy of each such report shall, at the time of such
transmission to Holders, be filed by the Trustee with each stock exchange upon
which any Securities are listed, with the Commission and with the Company. The
Company will notify the Trustee when any Securities are listed on any stock
exchange.

(S) 7.4.    Reports by Company.

certificate need not comply with Section 1.2.

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.

     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.

     The Trustee shall sign any supplemental indenture authorized pursuant to
this Article, subject to the last sentence of this Section 9.3.  In executing,
or accepting the additional trusts created by, any supplemental indenture
permitted by this Article or the modifications thereby of the trusts created by
this Indenture, the Trustee shall be entitled to receive, and (subject to
Section 6.1) shall be fully protected in relying upon, an Officer's Certificate
and an Opinion of Counsel stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture.  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.

(S) 9.4.    Effect of Supplemental Indentures.

     Upon the execution of any supplemental indenture under this Article, this

     Securities of any series authenticated and delivered after the execution of

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 authenticate and delivered by the Trustee in
exchange for Outstanding Securities of such series.

                                   COVENANTS

(S) 10.1.   Payments of Securities.

     With respect to each series of Securities, the Company will duly and
punctually pay the principal of (and premium, if any) and interest on such

(S) 10.2.   Maintenance of Office or Agency.

     The Company will maintain an office or agency in each Place of Payment
where Securities may be surrendered for registration of transfer or exchange or
for presentation for payment, where notices and demands to or upon the Company
in respect of the Securities and this Indenture may be served.  The Company will
give prompt written notice to the Trustee of the location, and any change in
location, of 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 address of the Trustee as set forth in Section 1.5
hereof.

     The Company may also from time to time designate one or more other offices
or agencies where the Securities may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations.  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 set forth in, or pursuant to, a Board Resolution or
indenture supplemental hereto with respect to a series of Securities, the
Company hereby initially designates the Corporate Trust Office as such office of
the Company.

(S) 10.3.   Corporate Existence.

     Subject to Article 8 hereof, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and that of each of its Subsidiaries and the rights (charter and
statutory) of the Company and its Subsidiaries; provided, however, that (a) the
Company shall not be required to preserve any such right, license or franchise
or the corporate existence of any of its Subsidiaries if the Board of Directors,
or the board of directors of the Subsidiary concerned, as the case may be, shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company or any of its Subsidiaries and that the loss thereof
is not materially disadvantageous to the Holders, and (b) nothing herein
contained shall prevent any Subsidiary of the Company from liquidating or
dissolving, or merging into, or consolidating with the Company (provided that
the Company shall be the continuing or surviving corporation) or with any one or
more Subsidiaries if the Board of Directors or the board of directors of the
Subsidiary concerned, as the case may be, shall so determine.

(S) 10.4.   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 material taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary material
to the Company and its Subsidiaries taken as a whole, and (2) all lawful claims
for labor, materials and supplies which, if unpaid, might by law become a
material lien upon the property of the Company

                                      -59-
<PAGE>
 
or any Subsidiary material to the Company and its Subsidiaries taken as a whole;
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 and for which adequate provision has been made.

(S) 10.5.   Compliance Certificates.
 
            (a) The Company shall deliver to the Trustee, within 10 days after
the occurrence thereof, notice of any acceleration which with the giving of
notice and the lapse of time would be an Event of Default within the meaning of
Section 5.1(4) hereof.
 
            (b) The Company shall deliver to the Trustee forthwith upon becoming
aware of a Default or Event of Default (but in no event later than 10 days after
the occurrence of each Default or Event of Default that is continuing), an
Officer's Certificate setting forth the details of such Default or Event of
Default and the action that the Company proposes to take with respect thereto
and the specific section or sections of this Indenture in connection with which
such Default or Event of Default has occurred.

(S) 10.6.   Commission Reports.
 
            (a) So long as the Securities remain outstanding, the Company shall
cause its annual report to shareholders and any other financial reports
furnished by it to shareholders generally, to be mailed to the Holders at their
addresses appearing in the register of Securities maintained by the Security
Registrar in each case at the time of such mailing or furnishing to
shareholders. If the Company is not required to furnish annual reports to its
shareholders pursuant to the Exchange Act, the Company shall cause its financial
statements, including any notes thereto and, with respect to annual reports, an
auditors' report by an accounting firm of established national reputation and a
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," to be so filed with the Trustee and mailed to the Holders within 90
days after the end of each of the Company's fiscal years and within 45 days
after the end of each of the first three quarters of each fiscal year.
 
            (b) The Company shall provide the Trustee with a sufficient number
of copies of all reports and other documents and information that the Company
may be required to deliver to the Holders under this Section 10.6.

(S) 10.7.   Waiver of Stay, Extension or Usury 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,
and will actively resist any and all efforts to be compelled to take the benefit
or advantage of, any stay or extension law or any usury law or other law, which
would prohibit or forgive the Company from paying all or any portion of the
principal of and/or interest on the Securities as contemplated herein, wherever
enacted, now or at any time hereafter in

                                      -60-
<PAGE>
 
force, or which may affect the covenants or the performance of this Indenture;
and (to the extent that it may lawfully do so) the Company 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.

(S) 10.8.   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 Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Securities of that
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
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, it will, prior to each due date of the principal of (and premium, if
any) or interest on any Securities of that series, deposit with a Paying Agent a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of its action or
failure to so act.

     The Company will cause each Paying Agent for any series of Securities
(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:

            (i) hold all sums held by it for the payment of the principal of
(and premium, if any) or interest on Securities of that series 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;
 
            (ii) give the Trustee notice of any default by the Company (or any
other obligor upon the Securities of that series) in the making of any payment
of principal (and premium, if any) or interest on the Securities of that series;
and

            (iii) 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

                                      -61-
<PAGE>
 
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 money.

     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, if any)
or interest on any security of any series and remaining unclaimed for two years
after such principal (and premium, if any) or interest has become due and
payable shall be paid to the Company on 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 thereof, 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 of such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on each Business Day and of general
circulation in New York, New York, 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.

                            REDEMPTION OF SECURITIES

(S) 11.1.   Applicability of Article.

     Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms in whole or in part (provided
Securities issued in denominations larger than $1,000 may be redeemed in part
only in integral multiples of $1,000) and (except as otherwise specified as
contemplated by Section 3.1 for Securities of any series) in accordance with
this Article.

(S) 11.2.   Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution.  In case of any redemption at the election of the Company of
less than all the Securities of any series, the Company shall, at least 45 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date and
of the principal amount of Securities of such series to be redeemed.  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
evidencing compliance with such restriction.

<PAGE>
 
(S) 11.3.   Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 90 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, substantially pro rata, by lot
or by any other method as the Trustee considers fair and appropriate and that
complies with the requirements of the principal national securities exchange, if
any, on which such Securities are listed, and which may provide for the
selection for redemption of portions (equal to the lesser of the minimum
authorized denomination for Securities of that series or $50 per Security, and
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; provided that in case the Securities of such series
have different terms and maturities, the Securities to be redeemed shall be
selected by the Company and the Company shall give notice thereof to the
Trustee.

     The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed.

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

(S) 11.4.   Notice of Redemption.

     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at this address appearing in the
security Register.

     All notices of redemption shall state:

            (1) the Redemption Date;
 
            (2) the Redemption Price;
 
            (3) if less than all the Outstanding Securities of any series are to
be redeemed, the identification (and, in the case of partial redemption, the
principal amounts) of the particular Securities to be redeemed;
 
            (4) that on the Redemption Date, the Redemption Price will become
due and payable upon each such security to be redeemed and, if applicable, that
interest thereon will cease to accrue on and after said date;
 

                                      -63-
<PAGE>
 
            (5) the place or places where such Securities are to be surrendered
for payment of the Redemption Price;
 
            (6) that the redemption is for a sinking fund, if such is the case;
 
            (7) the CUSIP number, if any, of the Securities to be redeemed; and
 
            (8) unless otherwise provided as to a particular series of
Securities, if at the time of publication or mailing of any notice of redemption
the Company shall not have deposited with the Trustee or Paying Agent and/or
irrevocably directed the Trustee or Paying Agent to apply, from money held by it
available to be used for the redemption of Securities, an amount in cash
sufficient to redeem all of the Securities called for redemption, including
accrued interest to the Redemption Date, such notice shall state that it is
subject to the receipt of the redemption moneys by the Trustee or Paying Agent
before the Redemption Date (unless such redemption is mandatory) and such notice
shall be of no effect unless such moneys are so received before such date.

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

(S) 11.5.   Deposit of Redemption Price.

     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,
segregate and hold in trust as provided in Section 10.98) an amount of money
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities which
are to be redeemed on that date.

(S) 11.6.   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, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest.  Upon surrender of any
such security for redemption in accordance with said notice, such security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that installments of interest 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 Regular or Special Record Dates
according to their terms and the provisions of Section 3.7.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate prescribed in the Security.

<PAGE>
 
(S) 11.7.   Securities Redeemed in Part.

     Any Security which is to be redeemed only in part shall be surrendered at
an office or agency of the Company 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 and Stated Maturity, 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.

                                 SINKING FUNDS

(S) 12.1.   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 3.1 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 Securities of any series is herein referred to as an "Optional Sinking
Fund Payment." If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to redemption as provided
in Section 12.2.  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.

(S) 12.2.   Satisfaction of Sinking Fund Payments with Securities.

     The Company (1) may deliver Securities of a series (other than any
Securities previously called for redemption) and (2) may apply as a credit
Securities of a series which have been (i) previously cancelled pursuant to
Section 3.9 or delivered for cancellation or (ii) 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, in each case in satisfaction of all or any part of any
Mandatory Sinking Fund Payment with respect to the Securities of such series
required to be made pursuant to the terms of such Securities as provided for by
the terms of such series; provided that such Securities have not been previously
so credited.  Such Securities shall be received and credited at the principal
amount for such purpose by the Trustee at the 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.

(S) 12.3.   Redemption of Securities for Sinking Fund.

     Not less than 45 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officer's
Certificate specifying the amount of the next ensuing 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 and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 12.2 and will also deliver to the Trustee any Securities to
be so delivered.  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 11.3 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 11.4.  Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 11.6 and 11.7.

                       DEFEASANCE AND COVENANT DEFEASANCE

(S) 13.1.   Applicability of Article; Company's Option to Effect Defeasance or
            Covenant Defeasance.

     Unless pursuant to Section 3.1 provision is made for the inapplicability of
either or both of (a) Defeasance of the Securities of a series under Section
13.2 or (b) Covenant Defeasance of the Securities of a series under Section
13.3, then the provisions of such Section or Sections, as the case may be,
together with the other provisions of this Article, shall be applicable to the
Securities of such series, and the Company may at its option by Board
Resolution, at any time, with respect to the Securities of such series, elect to
have either Section 13.2 (unless inapplicable) or Section 13.3 (unless
inapplicable) be applied to the Outstanding Securities of such series upon
compliance with the applicable conditions set forth below in this Article.

(S) 13.2.   Defeasance and Discharge.

     Upon the Company's exercise of the option provided in Section 13.1 to
defease the Outstanding Securities of a particular series, the Company shall be
discharged from its obligations with respect to the Outstanding Securities of
such series on the date the applicable conditions set forth in Section 13.4 are
satisfied (hereinafter, "Defeasance").  Defeasance shall mean that the Company
shall be deemed to have paid and discharged the entire indebtedness represented
by the Outstanding Securities of such series and to have satisfied all its other
obligations under such Securities and this Indenture insofar as such Securities
are concerned (and the Trustee, at the expense of the Company, shall execute
proper instruments acknowledging the same); provided, however, that the
following rights, obligations, powers, trusts, duties and immunities shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of Outstanding Securities of such series to receive, solely from the
trust fund provided for in

                                      -66-
<PAGE>
 
Section 13.4, payments in respect of the principal of (and premium, if any) and
interest on such Securities when such payments are due, (B) the Company's
obligations with respect to such Securities under Sections 3.4, 3.5, 3.6, 10.1,
10.2 and 10.8, (C) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and (D) this Article. Subject to compliance with this Article,
the Company may exercise its option with respect to Defeasance under this
Section 13.2 notwithstanding the prior exercise of its option with respect to
Covenant Defeasance under Section 13.3 in regard to the Securities of such
series.

(S) 13.3.   Covenant Defeasance.

     Upon the Company's exercise of the option provided in Section 13.1 to
obtain a Covenant Defeasance with respect to the Outstanding Securities of a
particular series, the Company shall be released from its obligations under this
Indenture (except its obligations under Sections 3.4, 3.5, 3.6, 5.6, 5.9, 6.10,
10.1, 10.2, 10.5, 10.7 and 10.8) with respect to the Outstanding Securities of
such series on and after the date the applicable conditions set forth in Section
1304 are satisfied (hereinafter, "Covenant Defeasance").  Covenant Defeasance
shall mean that, with respect to the Outstanding Securities of such series, the
Company may omit to comply with and shall have no liability in respect of any
term, condition or limitation set forth in this Indenture (except its
obligations under Sections 3.4, 3.5, 3.6, 5.6, 5.9, 6.10, 10.1, 10.2, 10.5, 10.7
and 10.8), whether directly or indirectly by reason of any reference elsewhere
herein or by reason of any reference to any other provision herein or in any
other document, and such omission to comply shall not constitute an Event of
Default under Section 5.1(4) with respect to Outstanding Securities of such
series, and the remainder of this Indenture and of the Securities of such series
shall be unaffected thereby.

(S) 13.4.   Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to Defeasance under Section 13.2 and
Covenant Defeasance under Section 13.3 with respect to the Outstanding
Securities of a particular series:

            (1) the Company shall irrevocably have deposited or caused to be
deposited (and in the case of Defeasance such deposit shall have been made 121
days prior to Defeasance with the Trustee (or another trustee satisfying the
requirements of Section 6.9 who shall agree to comply with the provisions of
this Article applicable to it), under the terms of an irrevocable trust
agreement in form and substance reasonably satisfactory to such 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, (A) Dollars in an amount, or (B) U.S. Government
Obligations which through the scheduled payment of principal and interest in
respect thereof in accordance with their terms will provide, not later than the
due date of any payment, money in an amount, or (C) a combination thereof, in
each case sufficient, after payment of all federal, state and local taxes or
other charges or

                                      -67-
<PAGE>
 
assessments in respect thereof payable by the Trustee, in the opinion of a
nationally recognized firm of independent public accountants expressed in a

Trustee (or other qualifying trustee--collectively for purposes of this Section
13.5, the "Trustee") pursuant to Section 13.4 in respect of the Outstanding
Securities of a particular series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent

     Anything in this Article to the contrary notwithstanding, the Trustee shall
deliver to pay to the Company from time to time upon Company Request any money
or Government Obligations held by it as provided in Section 13.4 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 for
the purpose for which such money or Government Obligations were deposited.

substantially similar tenor signed by such Holders in person or by agents 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 and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 6.1) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

          (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 manner which the Trustee deems sufficient.

Security Register.

          (d) Any request, demand, authorization, direction, notice, consent,

respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made upon
such Security.

          (e) If the Company shall solicit from the Holders any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may,
at its option, by 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. 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 six months after the
record date.

     (S) 1.5.  Notices, Etc., to Trustee and Company.

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, attention: Secretary, or at any other address previously furnished in
writing to the Trustee by the Company.

     (S) 1.6.  Notice to Holders; Waiver.

     Where this Indenture or any Security provides for notice to Holders of any
event, such notice shall be deemed sufficiently given (unless otherwise herein
or in such Security expressly provided) if in writing and mailed, first-class
postage prepaid, to each 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 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 or the
validity of the proceedings to which such notice relates.  Where this Indenture
or any Security 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

                                      -11-
<PAGE>
 
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.

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

     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.

     (S) 1.7.  Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required to be included in this Indenture by any of
the provisions of the Trust Indenture Act, such required provision shall
control.  If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act that may be so modified or excluded, the latter
provision shall be deemed to apply to this Indenture as so modified or shall be
excluded, as the case may be.

     (S) 1.8.  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.

     (S) 1.9.  Successors and Assigns.

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

     (S) 1.10.  Separability Clause.

     In case any provision in this Indenture or in the Securities 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.

     (S) 1.11.  Benefits of Indenture.

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

     (S) 1.12.  Governing Law.

     This Indenture and the Securities shall be governed by and construed in
accordance with the laws (other than the choice of law provisions) of the State
of New York.

     (S) 1.13.  Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities) payment of interest or principal (and premium, if any) need not be
made at such Place of Payment on such date, but may be made on the next
succeeding Business Day or on such other day as may be set out in the Officer's
Certificate pursuant to Section 3.1 at such Place of Payment with the same force
and effect as if made on the Interest Payment Date or Redemption Date, or at the
Stated Maturity, provided that no interest shall accrue for the period from and
after such Interest Payment Date, Redemption Date or Stated Maturity, as the
case may be.

     (S) 1.14.  No Recourse Against Others.

     A director, officer, employee or stockholder, as such, of the Company shall
not have any liability for any obligations of the Company under the Securities
or this Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation.  Each Security holder, by accepting a Security,
waives and releases all such liability.  Such waivers and releases are part of
the consideration for the issuance of the Securities.

     (Notwithstanding the foregoing, the Company may not, prior to _______
redeem any Securities of this series as contemplated by (clause (2) of) the

financial practice) of less than _______% per annum.)

of Securities of this series.) (Securities of this series acquired or redeemed
by the Company otherwise than through (mandatory) sinking fund payments may be

     (In the event of redemption of this Security in part only a new Security or

     (If the Security is not an Original Issue Discount Security, insert -- If
any Event of Default with respect to Securities of this series shall occur and

amount.) Upon payment (i) of the amount of principal so declared due and payable
and (ii) of interest on any overdue principal and overdue interest (in each case
to the extent that the payment of such interest shall be legally enforceable),
all of the Company's obligations in respect of the payment of the principal of

     This Security is a subordinated and unsecured obligation of the Company and
is subordinated and junior in right of payment to all other senior unsecured
obligations of the Company.

     This Security is subject to Defeasance as described in the Indenture.  The
Indenture may be modified by the Company and the Trustee without consent of any
Holder with respect to certain matters as described in the Indenture.  In
addition, the Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Securities at
the time Outstanding of each series to be affected.  The Indenture also contains
provisions permitting the Holders of a majority in principal amount of the
Securities of each series at the time Outstanding, on behalf of the Holders of
all Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences.  Any such consent or waiver by the Holder of this Security
shall bind such Holder and all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange hereof
or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Security.

<PAGE>
 
     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of, and premium, if any, and
interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Company in any place where the principal of (and premium, if any)
and interest on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this series,
of authorized denominations and for the same Stated Maturity and aggregate
principal amount, will be issued to the designated transferee or transferees.

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

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

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

     The Indenture imposes certain limitations on the ability of the Company to,
among other things, merge or consolidate with any other Person or sell, assign,
transfer or lease all or substantially all of its properties or assets (If other
covenants are applicable pursuant to the provisions of Section 3.1, insert
here).  All such covenants and limitations are subject to a number of important
qualifications and exceptions.  The Company must report periodically to the
Trustee on compliance with the covenants in the Indenture.

     A director, officer, employee or stockholder, as such, of the Company shall
not have any liability for any obligations of the Company under this Security or
the Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation.  Each Holder, by accepting a Security, waives and
releases all such liability.  The waiver and release are part of the
consideration for the issuance of this Security.

     (If applicable, insert -- Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures ("CUSIP"), the Company
has

                                      -19-

caused CUSIP numbers to be printed on the Securities of this series as a
convenience to the Holders of the Securities of this series. No representation

identification numbers printed hereon.)

defined in the Indenture shall have the meanings assigned to them in the
Indenture.

     (S) 2.5.  Securities in Global Form.

     If Securities of a series are issuable in global form, as contemplated by
Section 3.1, then, notwithstanding the provisions of Section 3.2, 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 from time to time endorsed thereon and that the
aggregate amount of Outstanding Securities represented thereby may from time to
time be reduced to reflect exchanges.  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 in such manner and upon
instructions 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 3.3 or
Section 3.4.  Subject to the provisions of Section 3.3 and, if applicable,
Section 3.4, the Trustee shall deliver and redeliver any Security in permanent
global form in the manner and upon instructions given by the Person or Persons
specified therein or in the applicable Company Order.  If a Company Order
pursuant to Section 3.3 or 3.4 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 1.2 and need not be accompanied by an Opinion of Counsel.

     The provisions of Section 3.9 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 1.2 and
need not be accompanied by an Opinion of Counsel) with regard to the reduction
in the principal amount of Securities represented thereby.

     Notwithstanding the provisions of Sections 2.1 and 3.7, unless otherwise
specified as contemplated by Section 3.1, payment of principal of, premium, if
any, and interest on any Security in permanent global form shall be made to the
Person or Persons specified therein.

                                      -22-
<PAGE>
 
     Notwithstanding the provisions of Section 3.8 and except as provided in the
preceding paragraph, the Company, the Trustee and any agent of the Company and
the Trustee shall treat a Person as the Holder of such principal amount of
Outstanding Securities represented by a permanent global Security as shall be
specified in a written statement of the Holder of such permanent global
Security.

     (S) 2.6.  CUSIP Number.

     The Company in issuing Securities of any series may use a "CUSIP" number,
and, if so, the Trustee may use the CUSIP number in notices of redemption or
exchange as a convenience to Holders of such series; provided, that any such
notice may state that no representation is made as to the correctness or
accuracy of the CUSIP number printed on the notice or on the Securities of such
series, and that reliance may be placed only on the other identification numbers
printed on the Securities, and any such redemption shall not be affected by any
defect in or omission of such numbers.  The Company will promptly notify the
Trustee of any change in the CUSIP number of any series of Securities.

     (S) 2.7.  Form of Legend for the Securities in Global Form.

     Any Security in global form authenticated and delivered hereunder shall
bear a legend in substantially the following form:

     "This Security is in global form within the meaning of the Indenture
hereinafter referred to and is registered in the name of a Common Depositary or

Securities in certificated form, this Security may not be transferred except as
a whole by the Common Depositary or a U.S. Depositary or by a nominee of the
Common Depositary or a nominee of the U.S. Depositary as the case may be."

                                      -25-
<PAGE>
 
     All Securities of any one series shall be substantially identical except as
to denomination and except as may otherwise be provided in or pursuant to such
Board Resolution and set forth in such Officer's Certificate or in any such
Indenture supplemental hereto.

     If any of the terms of the series are established by action taken pursuant
to a Board Resolution, a copy of an appropriate record of such action 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 Officer's
Certificate setting forth, or providing the manner for determining, the terms of
the Securities of such series.

     (S) 3.2.  Denominations.

     The Securities of each series shall be issuable in registered form without
coupons in such denominations as shall be specified as contemplated by Section
3.1.  In the absence of any such provisions with respect to the Securities of
any series, the Securities of such series shall be issuable in denominations of
$1,000 and any integral multiple thereof.

     (S) 3.3.  Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its Vice Chairman of the Board, its President or one of its Vice
Presidents, under its corporate seal reproduced thereon attested by its
Secretary or one of its Assistant Secretaries.  The signature of any of these
officers on the Securities may be manual or facsimile.  The seal of the Company
may be in the form of a facsimile thereof and may be impressed, affixed,
imprinted or otherwise reproduced on the Securities.  Typographical and other
minor errors or defects in any such reproduction of the seal or any such
signature shall not affect the validity or enforceability of any security that
has been duly authenticated and delivered by the Trustee.

     Securities 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.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series 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 make such Securities available for
delivery.  If the form or terms of the Securities of the series have been
established in or pursuant to one or more Board Resolutions as permitted by
Sections 2.1 and 3.1, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive, and (subject to Sections 315(a)
through

                                      -26-
<PAGE>
 
(d) of the Trust Indenture Act) shall be fully protected in relying upon, an
Opinion of Counsel stating,

          (a) if the form of such Securities has been established by or pursuant
to Board Resolution as permitted by Section 2.1, that such form has been
established in conformity with the provisions of this Indenture;

          (b) if the terms of such Securities have been established by or
pursuant to Board Resolution as permitted by Section 3.1, that such terms have
been established in conformity with the provisions of this Indenture;

          (c) that such Securities, when authenticated and delivered by the
Trustee and issued by the Company in the manner and subject to any conditions
specified in such Opinion of Counsel, will constitute valid and legally binding
obligations of the Company, enforceable in accordance with their terms, except
to the extent enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium and other similar laws affecting the
enforcement of creditors' rights generally and by the effect of general
principles of equity (regardless of whether enforceability is considered in a
proceeding in equity or at law); and

          (d) that no consent, approval, authorization, order, registration or
qualification of or with any court or any governmental agency or body having
jurisdiction over the Company is required for the execution and delivery of such
Securities by the Company, except such as have been obtained (except that no
opinion need be expressed as to state securities or Blue Sky laws).

     If such form or terms have been so established, 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 or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee, or in the written opinion of
counsel to the Trustee (which counsel may be an employee of the Trustee) such
authentication may not lawfully be made or would involve the Trustee in personal
liability.

     Notwithstanding the provisions of Section 3.1 and of the immediately
preceding paragraph, if all Securities of a series are not to be originally
issued at one time, it shall not be necessary to deliver the Officer's
Certificate otherwise required pursuant to Section 3.1 or the Company Order and
Opinion of Counsel otherwise required pursuant to the immediately preceding
paragraph at or prior to the time of authentication of each security of such
series if such documents are delivered at or prior to the authentication upon
original issuance of the first security of such series to be issued.

     If the Company shall establish pursuant to Section 3.1 that the Securities
of a series are to be issued in the form of one or more global Securities, then
the Company shall execute and the Trustee shall, in accordance with this Section
and the Company Order with respect to the authentication and delivery of such
series, authenticate and

                                      -27-
<PAGE>
 
deliver one or more global Securities that (i) shall be in an aggregate amount
equal to the aggregate principal amount specified in such Company Order, (ii)
shall be registered in the name of the Common Depositary or U.S. Depositary, as
the case may be, therefor or its nominee, and (iii) shall be made available for
delivery by the Trustee to such depositary or pursuant to such depositary's
instruction.

     Each depositary designated pursuant to Section 3.1 must, at the time of its
designation and at all times while it serves as depositary, be a clearing agency
registered under the Exchange Act and any other applicable statute or
regulation.

     Unless otherwise provided for in the form of security, each security shall
be dated the date of its authentication.

     No security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, 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.

     (S) 3.4.  Temporary Securities.

     Pending the preparation of definitive Securities of any series, the Company
may execute, and upon Company Order the Trustee shall authenticate and make
available for delivery, 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 and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

     In the case of Securities of any series, such temporary Securities may be
in global form, representing all or a portion of the Outstanding Securities of
such series.

     Except in the case of temporary Securities in global form (which shall be
exchanged in accordance with the provisions of Section 3.5), 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, the Company shall execute and the Trustee shall authenticate and make
available for delivery in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor.  Until so exchanged,

                                      -28-
<PAGE>
 
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.

     If temporary Securities of any series are issued in global form, any such
temporary global Security shall, unless otherwise provided therein, be delivered
to the office of a depositary or common depositary (the "COMMON DEPOSITARY") for
credit to the respective accounts of the beneficial owners of such Securities
(or to such other accounts as they may direct).

     (S) 3.5.  Registration, Registration of Transfer and Exchange.

     The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of registration of transfers of Securities.  The
Trustee is hereby appointed "Security Registrar" for the purpose of registering
Securities and transfers of Securities as herein provided.

     Upon surrender for registration of transfer of any security of any series
at the office or agency of the Company in Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and make available for
delivery, in the name of the designated transferee or transferees, one or more
new Securities of the same series, of any authorized denominations and of a like
aggregate principal amount and Stated Maturity.

     At the option of the Holder, Securities of any series may be exchanged for
other Securities of the same series, of any authorized denominations and of a
like aggregate principal amount and Stated Maturity, upon surrender of the
Securities to be exchanged at such office or agency.  Whenever any Securities
are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and make available for delivery, the Securities which the
Holder making the exchange is entitled to receive.

     Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 3.1, any permanent global security shall be exchangeable
only as provided in this paragraph.  If the beneficial owners of interests in a
permanent global security are entitled to exchange such interests for Securities
of such series and of like tenor and principal amount of another authorized form
and denomination, as specified and as subject to the conditions contemplated by
Section 3.1, then without unnecessary delay but in any event not later than the
earliest date on which such interests may be so exchanged, the Company shall
deliver to the Trustee definitive Securities of that series in aggregate
principal amount equal to the principal amount of such permanent global
security, executed by the Company.  On or after the earliest date on which such
interests may be so exchanged, such permanent global Securities shall be
surrendered from time to time by the Common Depositary or the U.S. Depositary,
as the case may be, and in accordance with instructions given to the Trustee and
the Common Depositary or the U.S.

                                      -29-
<PAGE>
 
Depositary, as the case may be (which instructions shall be in writing but need
not comply with Section 1.2 or be accompanied by an Opinion of Counsel), as
shall be specified in the Company Order with respect thereto to the Trustee, as
the Company's agent for such purpose, to be exchanged, in whole or in part, for
definitive Securities of the same series without charge. The Trustee shall
authenticate and make available for delivery, in exchange for each portion of
such surrendered permanent global security, a like aggregate principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor as the portion of such permanent global security to be exchanged which
shall be in the form of the Securities of such series; provided, however, that
no such exchanges may occur during a period beginning at the opening of business
15 days before the day of the mailing of a notice of redemption of Securities of
that series selected for redemption under Section 11.3 and ending at the close
of business on the day of such mailing. Promptly following any such exchange in
part, such permanent global Security shall be returned by the Trustee to the
Common Depositary or the U.S. Depositary, as the case may be, or such other
Common Depositary or U.S. Depositary referred to above in accordance with the
written instructions of the Company referred to above. If a Security in the form
specified for such series 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 interest or Defaulted
Interest, as the case may be, such interest or Defaulted Interest will not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of such security in the form specified for such series, 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 obligation, 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 Security presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to
the Company and the Security Registrar duly executed, by the Holder thereof or
his attorney duly authorized in writing.

Unless otherwise provided in the Securities to be transferred or exchanged, 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

                                      -30-
<PAGE>
 
or exchange of Securities, other than exchanges pursuant to Section 3.4, 9.6 or
11.7 not involving any transfer.

     The Company shall not be required (i) to issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 11.3 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any security so selected for redemption in whole or in
part, except the unredeemed portion of any security being redeemed in part.

     (S) 3.6.  Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security 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 notice to the
Company or the Trustee that such Security 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, a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

     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 issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security 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 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.

                                      -31-

     (S) 3.7.  Payment of Interest; Interest Rights Preserved.

     Interest on any Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid at the Place of Payment
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, except that at the option of the Company payment may be made
(i) except in the case of a global Security by check mailed to the address of
the Person entitled thereto as such address appears in the Securities Registrar
or (ii) by transfer to an account maintained by the Person entitled thereto as
specified in the Securities Registrar provided that proper transfer instructions
have been received by the Regular Record Date.

     Any interest on any Security of any series which 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 Holder
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 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 Security of such series
and the date of the proposed payment, and at the same time the Company shall
deposit with the Trustee an amount of money 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 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 Section
3.7 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 Securities of such series
at his 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 so mailed,
such Defaulted Interest shall be paid to the Persons in whose names the
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).

          (2) The Company may make payment of any Defaulted Interest on the
Securities of any series in any other lawful manner not inconsistent with the
requirements

                                      -32-
<PAGE>
 
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 to the Trustee of the proposed payment pursuant to this Section
3.7, such manner of payment shall be deemed practicable by the Trustee.

     Subject to the foregoing provisions of this Section, 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.

     (S) 3.8.  Persons Deemed Owners.

     Prior to due presentment of a 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 Security is registered as the owner of such Security
for the purpose of receiving payment of principal of (and premium, if any) and
(subject to Section 3.7) interest on such Security and for all other purposes
whatsoever, whether or not such 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.

     None of the Company, the Trustee or any agent of the Company or the Trustee
shall have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interest of a
Security in global form, or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interest.  Notwithstanding the
foregoing, with respect to any Security in global form, nothing herein shall
prevent the Company or 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 U.S. Depositary or Common Depositary (or its nominee), as a
Holder, with respect to such Security in global form or impair, as between such
U.S. Depositary or Common Depositary and owners of beneficial interests in such
Security in global form, the operation of customary practices governing the
exercise of the right of such U.S. Depositary or Common Depositary (or its
nominee) as holder of such Security in global form.

     (S) 3.9.  Cancellation.

     All Securities surrendered for payment, redemption, 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 shall be promptly cancelled 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 all Securities so delivered shall be promptly cancelled by the
Trustee.  No Securities shall be authenticated in lieu of or in exchange for any
Securities cancelled as provided in this Section, except as expressly permitted
by this Indenture.  All cancelled Securities shall be held by the Trustee and
may be destroyed (and, if so destroyed, certification of their destruction shall

the Company upon its request, unless, by a Company Order, the
Company shall direct that cancelled Securities be returned to it).

     (S) 3.10.  Computation of Interest.

     Except as otherwise specified as contemplated by Section 3.1 for 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.

                           SATISFACTION AND DISCHARGE

     (S) 4.1.  Satisfaction and Discharge of Indenture.

     This Indenture shall cease to be of further effect (except as to any
surviving rights of registration of transfer or exchange of Securities herein
expressly provided for or in the form of Security for such series), when the
Trustee, upon Company Request and at the expense of the Company, shall execute
proper instruments acknowledging satisfaction and discharge of this Indenture,
when

          (1)  either

          (A) all Securities theretofore authenticated and delivered (other than
(i) Securities which have been destroyed, lost or stolen and which have been
replaced or paid as provided in Section 3.6 and (ii) Securities 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 10.9) have been delivered to the Trustee for
cancellation; or

          (B)  all such Securities 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) are to be called for redemption within one 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,

and the Company, in the case of (i), (ii) or (iii) above, has deposited with the
Trustee as trust funds in trust for the purpose an amount sufficient to pay and
discharge the entire indebtedness on such Securities not theretofore delivered
to the Trustee for cancellation, for principal (and premium, if any) and
interest to the date of such deposit (in the case of

                                      -34-
<PAGE>
 
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 other sums payable
hereunder by the Company; and

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


     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7, the obligations of
the Company to any Authenticating Agent under Section 6.14 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee under Section 4.2 and the last
paragraph of Section 10.9 shall survive.

     (S) 4.2.  Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 10.9, all money
deposited with the Trustee pursuant to Section 4.1 shall be held in trust and
applied by it, in accordance with the provisions of the Securities 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, if
any) and interest for whose payment such money has been deposited with or
received by the Trustee.

                                    REMEDIES

     (S) 5.1.  Events of Default.

     "EVENT OF DEFAULT," wherever used herein with respect to Securities of any
series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or to 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):

          (1) the Company defaults in the payment of interest or any sinking
fund payment on any Security of that series when such interest becomes due and
payable and the default continues for a period of 60 days; provided, however,
that if the Company is permitted by the terms of the Securities of the
applicable series to defer the payment in question, the date on which such
payment is due and payable shall be the date on which the Company is required to
make payment following such deferral, if such deferral has been elected pursuant
to the terms of the Securities; or

                                      -35-
<PAGE>
 
          (2) the Company defaults in the payment of the principal of (or
premium, if any, on) any Security of that series when the same becomes due and
payable at Maturity, upon redemption (including redemptions under Article 11),
by declaration or otherwise; provided, however, that if the Company is permitted
by the terms of the Securities of the applicable series to defer the payment in
question, the date on which such payment is due and payable shall be the date on
which the Company is required to make payment following such deferral, if such
deferral has been elected pursuant to the terms of the Securities; or

          (3) the Company fails to observe or perform in any material respect
any of its other covenants, warranties or agreements in the Securities of that
series or in this Indenture (other than a covenant, agreement or warranty a
default in whose performance or whose breach is elsewhere in this Section
specifically dealt with or which has expressly been included in this Indenture
solely for the benefit of series of Securities other than that series), and the
failure to observe or perform continues for the period and after the notice
specified in the last paragraph of this Section; or

          (4) any event of default, as defined in any other indenture, mortgage,
or instrument under which there may be issued, or by which there may be secured
or evidenced, any Indebtedness of the Company (whether such Indebtedness now
exists or shall hereafter be created or incurred) shall occur and shall consist
of default in the payment of such Indebtedness at the maturity thereof (after
giving effect to any applicable grace period) or shall result in Indebtedness
becoming or being declared due and payable prior to the date on which it would
otherwise become due and payable, and such default in payment is not cured or
such acceleration shall not be rescinded or annulled within 30 days after
written notice to the Company from the Trustee or to the Company and to the
Trustee from the Holders of at least 25% in aggregate principal amount of the
Securities of that series at the time outstanding; provided that it shall not be
an Event of Default if the principal amount of Indebtedness (other than
Indebtedness represented by Securities issued pursuant to this Indenture) which
is not paid at maturity or the maturity of which is accelerated is less than or
equal to $25 million provided further that if, prior to a declaration of
acceleration of the maturity of the Securities of that series or the entry of
judgment in favor of the Trustee in a suit pursuant to Section 5.3, such default
shall be remedied or cured by the Company or waived by the holders of such
Indebtedness, then the Event of Default hereunder by reason thereof shall be
deemed likewise to have been thereupon remedied, cured or waived without further
action upon the part of either the Trustee or any of the Holders of the
Securities of that series, and provided further, that, subject to Sections 6.1
and 6.2, the Trustee shall not be charged with knowledge of any such default
unless written notice of such default shall have been given to the Trustee by
the Company, by a holder or an agent of a holder of any such Indebtedness, by
the trustee then acting under any indenture or other instrument under which such
default shall have occurred, or by the Holders of at least five percent in
aggregate principal amount of the Securities of that series at the time
Outstanding; or

                                      -36-
<PAGE>
 
          (5) the Company pursuant to or within the meaning of any Bankruptcy
Law (A) commences a voluntary case or proceeding under any Bankruptcy Law with
respect to itself, (B) consents to the entry of a judgment, decree or order for
relief against it in an involuntary case or proceeding under any Bankruptcy Law,
(C) consents to or acquiesces in the institution of bankruptcy or insolvency
proceedings against it, (D) applies for, consents to or acquiesces in the
appointment of or taking possession by a Custodian of the Company or for any
material part of its property, (E) makes a general assignment for the benefit of
its creditors or (F) takes any corporate action in furtherance of or to
facilitate, conditionally or otherwise, any of the foregoing; or

          (6) (i) a court of competent jurisdiction enters a judgment, decree or
order for relief in respect of the Company in an involuntary case or proceeding
under any Bankruptcy Law which shall (A) approve as properly filed a petition
seeking reorganization, arrangement, adjustment or composition in respect of the
Company, (B) appoint a Custodian of the Company or for any material part of its
property, or (C) order the winding-up or liquidation of its affairs, and such
judgment, decree or order shall remain unstayed and in effect for a period of 60
consecutive days; or (ii) any bankruptcy or insolvency petition or application
is filed, or any bankruptcy or insolvency proceeding is commenced against the
Company and such petition, application or proceeding is not dismissed within 60
days; or (iii) a warrant of attachment is issued against any material portion of
the property of the Company which is not released within 60 days of service; or

          (7) any other Event of Default provided with respect to Securities of
that series.

     A Default under clause (3) above is not an Event of Default until the
Trustee or the Holders of at least 25% in aggregate principal amount of the
Outstanding Securities of that series notify the Company of the Default and the
Company does not cure the Default within 90 days after receipt of the notice.
The notice must specify the Default, demand that it be remedied and state that
the notice is a "Notice of Default." When a Default under clause (3) above is
cured within such 90-day period, it ceases.

     (S) 5.2.  Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default with respect to Securities of any series (other than
an Event of Default specified in clause (5) or (6) of Section 5.1) occurs and is
continuing, the Trustee by notice in writing to the Company, or the Holders of
at least 25% in aggregate principal amount of the Outstanding Securities of that
series by notice in writing to the Company and the Trustee, may declare the
unpaid principal of and accrued interest to the date of acceleration (or, if the
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of that series) on all
the Outstanding Securities of that series to be due and payable immediately and,
upon any such declaration, the Outstanding Securities of that series (or
specified principal amount) shall become and be immediately due and payable.

                                      -37-
<PAGE>
 
     If an Event of Default specified in clause (5) or (6) of Section 5.1
occurs, all unpaid principal of and accrued interest on the Outstanding
Securities of that series (or specified principal amount) shall ipso facto
become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any Holder of any Security of that series.

     Upon payment of all such principal and interest, all of the Company's
obligations under the Securities of that series and (upon payment of the
Securities of all series) this Indenture shall terminate, except obligations
under Section 6.7.

     The Holders of a majority in principal amount of the Outstanding Securities
of that series by notice to the Trustee may rescind an acceleration and its
consequences if (i) all existing Events of Default, other than the nonpayment of
the principal and interest of the Securities of that series that has become due
solely by such declaration of acceleration, have been cured or waived, (ii) to
the extent the payment of such interest is lawful, interest on overdue
installments of interest and overdue principal that has become due otherwise
than by such declaration of acceleration have been paid, (iii) the rescission
would not conflict with any judgment or decree of a court of competent
jurisdiction and (iv) all payments due to the Trustee and any predecessor
Trustee under Section 6.7 have been made.

     (S) 5.3.  Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if:

          (1) default is made in the payment of any interest on any Security of
any series when such interest 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, if
any, on) any Security of any series at the Maturity thereof, the Company will,
upon demand of the Trustee, pay to it, for the benefit of the Holders of such
Securities, the whole amount then due and payable on such Securities for
principal (and premium, if any) and interest and, to the extent that payment of
such interest shall be legally enforceable, interest on any overdue principal
(and premium, if any) and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the reasonable 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, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be

                                      -38-
<PAGE>
 
payable in the manner provided by law out of the property of the Company or any
other obligor upon such Securities, 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 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 secure any other proper remedy.

     (S) 5.4.  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
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 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 of principal (and
premium, if any) and interest 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 agent and
counsel) and of the Holders allowed in such judicial proceedings, 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 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 it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 6.7.

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

     (S) 5.5.  Trustee May Enforce Claims Without Possession of Securities.

     All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities 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 in respect of which such judgment has been
recovered.

     (S) 5.6.  Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article in respect of
the Securities of any series 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, if any) or interest, upon
presentation of the Securities in respect of which moneys have been collected
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 under Section 6.7
applicable to such series;

     Second:  To the payment of the amounts then due and unpaid for principal of
(and premium, if any) and interest on the Securities of such series 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 amounts due and
payable on such Securities of such series for principal (and premium, if any)
and interest, respectively; and

     Third:  To the Company.

     The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 5.6.  At least fifteen (15) days before such
record date, the Trustee shall mail to each Holder and the Company a notice that
states the record date, the payment date and the amount to be paid.

     (S) 5.7.  Limitation on Suits.

     No Holder of any Security of any series 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;

                                      -40-
<PAGE>
 
          (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 reasonable
indemnity 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 of a majority in
principal amount of the Outstanding Securities of that series; it being
understood and intended that no one or more of Holders of Securities of any
series 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 Holders of Securities of the affected series.

     (S) 5.8.  Unconditional Right of Holders to Receive Principal, Premium and
               Interest.

     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of (and premium, if any) and (subject to Section 3.7)
interest on such Security on the Stated Maturity or Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.

     (S) 5.9.  Restoration of Rights and Remedies.

     If the Trustee or any Holder 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, subject to any determination in
such proceeding, the Company, the Trustee and the Holders shall 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.

     (S) 5.10. Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
3.6, no right

                                      -41-
<PAGE>
 
or remedy herein conferred upon or reserved to the Trustee or to the Holders 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.

     (S) 5.11.  Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Securities 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 an
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, as the case may
be.

     (S) 5.12.  Control by Holders.

     The Holders of 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) subject to Section 6.1, the Trustee need not take any action which
might involve the Trustee in personal liability or be unduly prejudicial to the
Holders not joining therein.

     (S) 5.13.  Waiver of Past Defaults.

     The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may by written notice to the Trustee on
behalf of the Holders of all the Securities of such series waive any Default or
Event of Default with respect to such series and its consequences, except a
Default or Event of Default

     (1) in respect of the payment of the principal of (or premium, if any) or
interest on any Security of such series, or

     (2) in respect of a covenant or other 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.

                                      -42-
<PAGE>
 
          (3) Upon any such waiver, such Default or Event of Default shall cease
to exist and shall be deemed to have been cured, for every purpose of this
Indenture and the Securities of such series; but no such waiver shall extend to
any subsequent or other Default or Event of Default or impair any right
consequent thereon.

     (S) 5.14.  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,
suffered 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
Company, to any suit instituted by 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 of any series, or to any suit instituted by
any Holder for the enforcement of the payment of the principal of (or premium,
if any) or interest on any Security on or after the Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).

                                   ARTICLE 6


                                  THE TRUSTEE

     (S) 6.1.  Certain Duties and Responsibilities of the Trustee.

          (a) Except during the continuance of an Event of Default, the
Trustee's duties and responsibilities under this Indenture shall be governed by
Section 315(a) of the Trust Indenture Act.

          (b) In case an Event of Default has occurred and is continuing, and is
known to the Trustee, the Trustee shall exercise the rights and powers vested in
it by this Indenture, and shall use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

          (c) None of the provisions of Section 315(d) of the Trust Indenture
Act shall be excluded from this Indenture.

     (S) 6.2.  Notice of Defaults.

     Within 30 days after the occurrence of any Default or Event of Default with
respect to the Securities of any series, the Trustee shall give to all Holders
of Securities of such series, as their names and addresses appear in the
Security Register, notice of such

                                      -43-
<PAGE>
 
Default or Event of Default known to the Trustee, unless such Default or Event
of Default shall have been cured or waived; provided, however, that, except in
the case of a Default or Event of Default in the payment of the principal of (or
premium, if any) or interest on any Security of such series or in the payment of
any sinking fund installment with respect to Securities of such series, the
Trustee shall be protected in withholding such notice if and so long as the
board of directors, the executive committee or directors or Responsible Officers
of the Trustee in good faith determine that the withholding of such notice is in
the interest of the Holders of Securities of such series.

     (S) 6.3.  Certain Rights of Trustee.

     Subject to the provisions of the Trust Indenture Act:

          (a) the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document believed by it
to be genuine and to have been signed or presented by the proper party or
parties;

          (b) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order and any resolution
of the Board of Directors may be sufficiently evidenced by a Board Resolution;

          (c) 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 Officer's Certificate;

          (d) the Trustee may consult with counsel and the written 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;

          (e) 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 pursuant to this Indenture, unless such Holders shall have
offered to the Trustee security or indemnity to its reasonable satisfaction
against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction;

          (f) prior to the occurrence of an Event of Default with respect to the
Securities of any series and after the curing or waiving of all such Events of
Default which may have occurred, 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, approval or other paper or document, or the books and records of the
Company, unless requested in writing to do so by the Holders of a majority in
principal amount of the Outstanding Securities of any series;

                                      -44-
<PAGE>
 
provided, however, that if the payment within a reasonable time to the Trustee
of the costs, expenses or liabilities likely to be incurred by it in the making
of such investigation is not, in the opinion of the Trustee, reasonably assured
to the Trustee by the security afforded to it by the terms of this Indenture,
the Trustee may require reasonable indemnity against such costs, expenses or
liabilities as a condition to so proceeding; the reasonable expense of every
such investigation shall be paid by the Company or, if paid by the Trustee,
shall be repaid by the Company upon demand;

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

          (h) 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 its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

     (S) 6.4.  Not Responsible for Recitals or Issuance of Securities.

     The recitals herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee or any Authenticating Agent assumes no responsibility for their
correctness.  The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities.  Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

     (S) 6.5.  May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
6.8 and 6.13, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

     (S) 6.6.  Money Held in Trust.

     Money held by the Trustee in trust hereunder (including amounts held by the
Trustee as Paying Agent) need not be segregated from other funds except to the
extent required by law.  The Trustee shall be under no liability for interest on
any money received by it hereunder except as otherwise agreed upon in writing
with the Company.

     (S) 6.7.  Compensation and Reimbursement.

     The Company agrees

                                      -45-
<PAGE>
 
          (1) to pay to the Trustee from time to time reasonable compensation
for all services rendered by it 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) except as otherwise expressly provided herein, to reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any provision of this
Indenture (including the reasonable compensation and the expenses and
disbursements of its agents and counsel), except any such expense, disbursement
or advance as may be attributable to its negligence or bad faith; and

          (3) to indemnify the Trustee for, and to hold it harmless against, any
loss, liability, damage, claim or expense, including taxes (other than taxes
based upon or determined or measured by the income of the Trustee), incurred
without gross negligence or bad faith on its part, arising out of or in
connection with the acceptance or administration of the trust or trusts
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.

     When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 5.1(5) or Section 5.1(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

     The provisions of this Section 6.7 shall survive this Indenture and the
resignation or removal of any Trustee hereunder.

     (S) 6.8.  Disqualification; Conflicting Interests.

     The Trustee shall be disqualified only where such disqualification is
required by Section 310(b) of the Trust Indenture Act.  Nothing shall prevent
the Trustee from filing with the Commission the application referred to in the
second to last paragraph of Section 310(b) of the Trust Indenture Act.

     (S) 6.9.  Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee hereunder which shall be eligible to
act as Trustee under Section 310(a)(1) of the Trust Indenture Act having a
combined capital and surplus of at least $50,000,000 subject to supervision or
examination by federal or State authority.  If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of said supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published.  Neither the Company nor any Person directly or
indirectly controlling, controlled by, or under common control with the Company
may serve as

                                      -46-
<PAGE>
 
Trustee.  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.

     (S) 6.10.  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 6.11.

          (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 the
instrument of acceptance by a successor Trustee required by Section 6.11 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 with respect to the
Securities of such series.

          (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 Section 310(b) of the Trust
Indenture Act after written request therefor by the Company or by any Holder 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 6.9 and shall
fail to resign after written request here for by the Company or by any such
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 a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 315(e) of the
Trust Indenture Act, any Holder 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

                                      -47-
<PAGE>
 
the Securities of one or more series, the Company, by 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) and shall comply with the applicable
requirements of Section 6.11. 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 in
accordance with the applicable requirements of Section 6.11, become the
successor Trustee with respect to the Securities of such series and to that
extent supersede the successor Trustee appointed by the Company with respect to
such Securities. If no successor Trustee with respect to the Securities of any
series shall have been so appointed by the Company or the Holders and accepted
appointment in the manner required by Section 6.11, any Holder 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 the 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 by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
security Register. 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.

     (S) 6.11.  Acceptance of Appointment by Successor or Additional Trustees.

          (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed 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 the 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.

          (b) In case of the appointment hereunder of a Trustee or a successor
with respect to the Securities of one or more (but not all) series, the Company,
any retiring Trustee and each Trustee or a successor Trustee with respect to the
Securities of

                                      -48-
<PAGE>
 
one or more series shall execute and deliver an indenture supplemental hereto
wherein each Trustee or a 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 Trustee or a successor Trustee all
the rights, powers, trusts and duties of any retiring Trustee with respect to
the Securities of that or those series to which the appointment of such Trustee
or a successor Trustee relates, (2) if any 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 any retiring Trustee with respect to the Securities of that or those series
as to which any retiring Trustee is not retiring shall continue to be vested in
any 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 Trustee or a successor Trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, trusts and
duties of any retiring Trustee with respect to the Securities of that or those
series to which the appointment of such Trustee or a successor Trustee relates;
but, on request of the Company or any Trustee or a successor Trustee, any such
retiring Trustee shall duly assign, transfer and deliver to such Trustee or a
successor Trustee all property and money held by any such retiring Trustee
hereunder with respect to the Securities of that or those series to which the
appointment of any such Trustee or 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 the Trust Indenture Act.

          (S) 6.12.  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 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 shall have been
authenticated, but

                                      -49-
<PAGE>
 
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 so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

     (S) 6.13.  Preferential Collection of Claims Against Company.

     The Trustee shall comply with Section 311(a) of the Trust Indenture Act,
excluding any creditor relationship listed in Section 311(b) of the Trust
Indenture Act.  A Trustee who has resigned or been removed shall be subject to
Section 311(a) of the Trust Indenture Act to the extent indicated therein.

     (S) 6.14.  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, and subject to the
direction of, the Trustee to authenticate Securities of such series issued upon
exchange, registration of transfer or partial redemption thereof or pursuant to
Section 3.6, and Securities so authenticated shall be entitled to the benefits
of this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder.  Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent.  Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $5,000,000 and
subject to supervision or examination by federal or State authority.  If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said 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.  If 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 any further
act on the part of the Trustee or the Authenticating Agent.

                                      -50-
<PAGE>
 
     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the security Register.  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.
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 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 lieu
of the Trustee's certificate of authentication, an alternate certificate of
authentication in the following form:

          Form of Authenticating Agent's

               HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

     (S) 7.1.  Company to Furnish Trustee Names and Addresses of Holders.

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

          (a) semi-annually, not later than January 1 and July 1 in each year, a
list, in such form as the Trustee may reasonably require, of the names and
addresses of the Holders as of the preceding December 15 or June 15, as the case
may be; 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 list shall be required to be furnished; provided, however,
that so long as the Trustee is the Security Registrar, no such list shall be
required to be furnished.

     (S) 7.2.  Preservation of Information; Communications to Holders.

          (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 7.1 and the names and
addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 7.1 upon receipt of a new list so furnished.

          (b) If three or more Holders (herein referred to as "applicants")
apply in writing to the Trustee, and furnish to the Trustee reasonable proof
that each such applicant has owned a Security for a period of at least six
months preceding the date of such application, and such application states that
the applicants desire to communicate with other Holders with respect to their
rights under this Indenture or under the Securities and is accompanied by a copy
of the form of proxy or other communication which such applicants propose to
transmit then the Trustee shall, within five Business Days after the receipt of
such application, at its election, either

          (i) afford such applicants access to the information preserved at the
time by the Trustee in accordance with Section 7.2(a); or

          (ii) inform such applicants as to the approximate number of Holders
whose names and addresses appear in the information preserved at the time by the
Trustee in accordance with Section 7.2(a), and as to the approximate cost of
mailing to such Holders the form of proxy or other communication, if any,
specified in such application.

                                      -52-
<PAGE>
 
     If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder whose name and address appears in the information preserved
at the time by the Trustee in accordance with Section 7.2(a) a copy of the form
of proxy or other communication which is specified in such request, with
reasonable promptness after a tender to the Trustee of the material to be mailed
and of payment, or provision for the payment, of the reasonable expenses of
mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interest of the Holders
or would be in violation of applicable law.  Such written statement shall
specify the basis of such opinion.  If the Commission, after opportunity for a
hearing upon the objections specified in the written statement so filed, shall
enter an order refusing to sustain any of such objections or if, after the entry
of an order sustaining one or more of such objections, the Commission shall
find, after notice and opportunity for hearing, that all objections so sustained
have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all such Holders with reasonable promptness after the
entry of such order and the renewal of such tender; otherwise the Trustee shall
be relieved of any obligation or duty to such applicants respecting their
application.

          (c) Every Holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
nor any agent of either of them shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the Holders
in accordance with Section 702(b), 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 Section 7.2(b).

      (S) 7.3.  Reports by Trustee.

          (a) Within 60 days after May 15 of each year commencing with the
year 1998, the Trustee shall transmit by mail to all Holders of Securities as
provided in Section 313(c) of the Trust Indenture Act, a brief report dated as
of May 15, if required by and in compliance with Section 313(a) of the Trust
Indenture Act.

          (b) A copy of each such report shall, at the time of such transmission
to Holders, be filed by the Trustee with each stock exchange upon which any
Securities are listed, with the Commission and with the Company. The Company
will notify the Trustee when any Securities are listed on any stock exchange.

     (S) 7.4.  Reports by Company.

     The Company shall:

          (1) file with the Trustee, within 30 days after the Company is
required to file the same with the Commission, copies of the annual reports and
of the information,

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 said
Sections, then it shall file with the Trustee and the Commission, in accordance
with rules and regulations prescribed from time to time by the Commission, such
of the supplementary and periodic information, documents and reports which may
be required pursuant to Section 13 of the Exchange Act in respect of a security
listed and registered on a national securities exchange as may be prescribed
from time to time in such rules and regulations;

with the conditions and covenants of this Indenture as may be required from time
to time by such rules and regulations;

          (3) furnish to the Trustee, on or before May 1 of each 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. For purposes
of this paragraph, such compliance shall be determined without regard to any
period of grace or requirement of notice provided under this Indenture. Such
certificate need not comply with Section 1.2.

sell, assign, transfer or lease or otherwise dispose of all or substantially all
of its properties and assets as an entirety or substantially as an entirety to

or

          (6)  to secure the Securities; or

          (7) to establish the form or terms of Securities of any series as

of Section 6.11(b); or

          (9) to cure any ambiguity, defect or inconsistency or to correct or

authorized by a Board Resolution, and the Trustee shall, subject to Section 9.3,
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

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 any installment
of principal of or interest on, any security, or reduce the principal amount
thereof or the rate of interest thereon or any premium payable upon the

Redemption Date);

          (2) reduce the percentage in principal amount of the Outstanding

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.

     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.

     (S) 10.2.  Maintenance of Office or Agency.

     The Company will maintain an office or agency in each Place of Payment
where Securities may be surrendered for registration of transfer or exchange or
for presentation for payment, where notices and demands to or upon the Company
in respect of the Securities and this Indenture may be served.  The Company will
give prompt written notice to the Trustee of the location, and any change in
location, of 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 address of the Trustee as set forth in Section 1.5
hereof.

or agencies where the Securities may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations.  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 set forth in, or pursuant to, a Board Resolution or
indenture supplemental hereto with respect to a series of Securities, the
Company hereby initially designates the Corporate Trust Office as such office of
the Company.

     (S) 10.3.  Corporate Existence.

     Subject to Article 8 hereof, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and that of each of its Subsidiaries and the rights (charter and
statutory) of the Company and its Subsidiaries; provided, however, that (a) the
Company shall not be required to preserve any such right, license or franchise
or the corporate existence of any of its Subsidiaries if the Board of Directors,
or the board of directors of the Subsidiary concerned, as the case may be, shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company or any of its Subsidiaries and that the loss thereof
is not materially disadvantageous to the Holders, and (b) nothing herein
contained shall prevent any Subsidiary of the Company from liquidating or
dissolving, or merging into, or consolidating with the Company (provided that
the Company shall be the continuing or surviving corporation) or with any one or
more Subsidiaries if the Board of Directors or the board of directors of the
Subsidiary concerned, as the case may be, shall so determine.

     (S) 10.4.  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 material taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary material
to the Company and its Subsidiaries taken as a whole, and (2) all lawful claims
for labor, materials and supplies which, if unpaid, might by law become a
material lien upon the property of the Company

                                      -59-
<PAGE>
 
or any Subsidiary material to the Company and its Subsidiaries taken as a whole;
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 and for which adequate provision has been made.

     (S) 10.5.  Compliance Certificates.

          (a) The Company shall deliver to the Trustee, within 10 days after the
occurrence thereof, notice of any acceleration which with the giving of notice
and the lapse of time would be an Event of Default within the meaning of Section
5.1(4) hereof.

          (b) The Company shall deliver to the Trustee forthwith upon becoming
aware of a Default or Event of Default (but in no event later than 10 days after
the occurrence of each Default or Event of Default that is continuing), an
Officer's Certificate setting forth the details of such Default or Event of
Default and the action that the Company proposes to take with respect thereto
and the specific section or sections of this Indenture in connection with which
such Default or Event of Default has occurred.

     (S) 10.6.  Commission Reports.

          (a) So long as the Securities remain outstanding, the Company shall
cause its annual report to shareholders and any other financial reports
furnished by it to shareholders generally, to be mailed to the Holders at their
addresses appearing in the register of Securities maintained by the Security
Registrar in each case at the time of such mailing or furnishing to
shareholders. If the Company is not required to furnish annual reports to its
shareholders pursuant to the Exchange Act, the Company shall cause its financial
statements, including any notes thereto and, with respect to annual reports, an
auditors' report by an accounting firm of established national reputation and a
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," to be so filed with the Trustee and mailed to the Holders within 90
days after the end of each of the Company's fiscal years and within 45 days
after the end of each of the first three quarters of each fiscal year.

          (b) The Company shall provide the Trustee with a sufficient number of
copies of all reports and other documents and information that the Company may
be required to deliver to the Holders under this Section 10.6.

     (S) 10.7.  Waiver of Stay, Extension or Usury 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,
and will actively resist any and all efforts to be compelled to take the benefit
or advantage of, any stay or extension law or any usury law or other law, which
would prohibit or forgive the Company from paying all or any portion of the
principal of and/or interest on the Securities as contemplated herein, wherever
enacted, now or at any time hereafter in

                                      -60-
<PAGE>
 
force, or which may affect the covenants or the performance of this Indenture;
and (to the extent that it may lawfully do so) the Company 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.

     (S) 10.8.  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 Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Securities of that
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
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, it will, prior to each due date of the principal of (and premium, if
any) or interest on any Securities of that series, deposit with a Paying Agent a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of its action or
failure to so act.

     The Company will cause each Paying Agent for any series of Securities
(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:

           (i) hold all sums held by it for the payment of the principal of (and
premium, if any) or interest on Securities of that series 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;

          (ii) give the Trustee notice of any default by the Company (or any
other obligor upon the Securities of that series) in the making of any payment
of principal (and premium, if any) or interest on the Securities of that series;
and

          (iii) 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

                                      -61-
<PAGE>
 
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 money.

     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, if any)
or interest on any security of any series and remaining unclaimed for two years
after such principal (and premium, if any) or interest has become due and
payable shall be paid to the Company on 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 thereof, 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 of such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on each Business Day and of general
circulation in New York, New York, 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.

                            REDEMPTION OF SECURITIES

     (S) 11.1.  Applicability of Article.

     Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms in whole or in part (provided
Securities issued in denominations larger than $1,000 may be redeemed in part
only in integral multiples of $1,000) and (except as otherwise specified as
contemplated by Section 3.1 for Securities of any series) in accordance with
this Article.

     (S) 11.2.  Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution.  In case of any redemption at the election of the Company of
less than all the Securities of any series, the Company shall, at least 45 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date and
of the principal amount of Securities of such series to be redeemed.  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
evidencing compliance with such restriction.

<PAGE>
 
     (S) 11.3.  Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 90 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, substantially pro rata, by lot
or by any other method as the Trustee considers fair and appropriate and that
complies with the requirements of the principal national securities exchange, if
any, on which such Securities are listed, and which may provide for the
selection for redemption of portions (equal to the lesser of the minimum
authorized denomination for Securities of that series or $50 per Security, and
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; provided that in case the Securities of such series
have different terms and maturities, the Securities to be redeemed shall be
selected by the Company and the Company shall give notice thereof to the
Trustee.

     The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed.

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

     (S) 11.4.  Notice of Redemption.

     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at this address appearing in the
security Register.

     All notices of redemption shall state:

          (1)  the Redemption Date;

          (2)  the Redemption Price;

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

          (4) that on the Redemption Date, the Redemption Price will become due
and payable upon each such security to be redeemed and, if applicable, that
interest thereon will cease to accrue on and after said date;

                                      -63-
<PAGE>
 
          (5) the place or places where such Securities are to be surrendered
for payment of the Redemption Price;

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

          (7)  the CUSIP number, if any, of the Securities to be redeemed; and

          (8) unless otherwise provided as to a particular series of Securities,
if at the time of publication or mailing of any notice of redemption the Company
shall not have deposited with the Trustee or Paying Agent and/or irrevocably
directed the Trustee or Paying Agent to apply, from money held by it available
to be used for the redemption of Securities, an amount in cash sufficient to
redeem all of the Securities called for redemption, including accrued interest
to the Redemption Date, such notice shall state that it is subject to the
receipt of the redemption moneys by the Trustee or Paying Agent before the
Redemption Date (unless such redemption is mandatory) and such notice shall be
of no effect unless such moneys are so received before such date.


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

     (S) 11.5.  Deposit of Redemption Price.

     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,
segregate and hold in trust as provided in Section 10.98) an amount of money
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities which
are to be redeemed on that date.

     (S) 11.6.  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, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest.  Upon surrender of any
such security for redemption in accordance with said notice, such security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that installments of interest 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 Regular or Special Record Dates
according to their terms and the provisions of Section 3.7.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate prescribed in the Security.

                                      -64-
<PAGE>
 
     (S) 11.7.  Securities Redeemed in Part.

     Any Security which is to be redeemed only in part shall be surrendered at
an office or agency of the Company 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 and Stated Maturity, 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 12

the retirement of Securities of a series, except as otherwise specified as
contemplated by Section 3.1 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 Securities of any series is herein referred to as an "Optional Sinking
Fund Payment." If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to redemption as provided
in Section 12.2.  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.

     (S) 12.2.  Satisfaction of Sinking Fund Payments with Securities.

     The Company (1) may deliver Securities of a series (other than any
Securities previously called for redemption) and (2) may apply as a credit
Securities of a series which have been (i) previously cancelled pursuant to
Section 3.9 or delivered for cancellation or (ii) 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, in each case in satisfaction of all or any part of any
Mandatory Sinking Fund Payment with respect to the Securities of such series
required to be made pursuant to the terms of such Securities as provided for by
the terms of such series; provided that such Securities have not been previously
so credited.  Such Securities shall be received and credited at the principal
amount for such purpose by the Trustee at the 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.

     (S) 12.3.  Redemption of Securities for Sinking Fund.

     Not less than 45 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officer's
Certificate specifying the amount of the next ensuing 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 and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 12.2 and will also deliver to the Trustee any Securities to
be so delivered.  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 11.3 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 11.4.  Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 11.6 and 11.7.

                       DEFEASANCE AND COVENANT DEFEASANCE

     (S) 13.1.  Applicability of Article; Company's Option to Effect
                Defeasance or Covenant Defeasance.

     Unless pursuant to Section 3.1 provision is made for the inapplicability of
either or both of (a) Defeasance of the Securities of a series under Section
13.2 or (b) Covenant Defeasance of the Securities of a series under Section
13.3, then the provisions of such Section or Sections, as the case may be,
together with the other provisions of this Article, shall be applicable to the
Securities of such series, and the Company may at its option by Board
Resolution, at any time, with respect to the Securities of such series, elect to
have either Section 13.2 (unless inapplicable) or Section 13.3 (unless
inapplicable) be applied to the Outstanding Securities of such series upon
compliance with the applicable conditions set forth below in this Article.

     (S) 13.2.  Defeasance and Discharge.

     Upon the Company's exercise of the option provided in Section 13.1 to
defease the Outstanding Securities of a particular series, the Company shall be
discharged from its obligations with respect to the Outstanding Securities of
such series on the date the applicable conditions set forth in Section 13.4 are
satisfied (hereinafter, "Defeasance").  Defeasance shall mean that the Company
shall be deemed to have paid and discharged the entire indebtedness represented
by the Outstanding Securities of such series and to have satisfied all its other
obligations under such Securities and this Indenture insofar as such Securities
are concerned (and the Trustee, at the expense of the Company, shall execute
proper instruments acknowledging the same); provided, however, that the
following rights, obligations, powers, trusts, duties and immunities shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of Outstanding Securities of such series to receive, solely from the
trust fund provided for in

                                      -66-
<PAGE>
 
Section 13.4, payments in respect of the principal of (and premium, if any) and
interest on such Securities when such payments are due, (B) the Company's
obligations with respect to such Securities under Sections 3.4, 3.5, 3.6, 10.1,
10.2 and 10.8, (C) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and (D) this Article. Subject to compliance with this Article,
the Company may exercise its option with respect to Defeasance under this
Section 13.2 notwithstanding the prior exercise of its option with respect to
Covenant Defeasance under Section 13.3 in regard to the Securities of such
series.

     (S) 13.3.  Covenant Defeasance.

     Upon the Company's exercise of the option provided in Section 13.1 to
obtain a Covenant Defeasance with respect to the Outstanding Securities of a
particular series, the Company shall be released from its obligations under this
Indenture (except its obligations under Sections 3.4, 3.5, 3.6, 5.6, 5.9, 6.10,
10.1, 10.2, 10.5, 10.7 and 10.8) with respect to the Outstanding Securities of
such series on and after the date the applicable conditions set forth in Section
1304 are satisfied (hereinafter, "Covenant Defeasance").  Covenant Defeasance
shall mean that, with respect to the Outstanding Securities of such series, the
Company may omit to comply with and shall have no liability in respect of any
term, condition or limitation set forth in this Indenture (except its
obligations under Sections 3.4, 3.5, 3.6, 5.6, 5.9, 6.10, 10.1, 10.2, 10.5, 10.7
and 10.8), whether directly or indirectly by reason of any reference elsewhere
herein or by reason of any reference to any other provision herein or in any
other document, and such omission to comply shall not constitute an Event of
Default under Section 5.1(4) with respect to Outstanding Securities of such
series, and the remainder of this Indenture and of the Securities of such series
shall be unaffected thereby.

     (S) 13.4.  Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to Defeasance under Section 13.2 and
Covenant Defeasance under Section 13.3 with respect to the Outstanding
Securities of a particular series:

          (1) the Company shall irrevocably have deposited or caused to be
deposited (and in the case of Defeasance such deposit shall have been made 121
days prior to Defeasance with the Trustee (or another trustee satisfying the
requirements of Section 6.9 who shall agree to comply with the provisions of
this Article applicable to it), under the terms of an irrevocable trust
agreement in form and substance reasonably satisfactory to such 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, (A) Dollars in an amount, or (B) U.S. Government
Obligations which through the scheduled payment of principal and interest in
respect thereof in accordance with their terms will provide, not later than the
due date of any payment, money in an amount, or (C) a combination thereof, in
each case sufficient, after payment of all federal, state and local taxes or
other charges or

                                      -67-

assessments in respect thereof payable by the Trustee, 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 (or other qualifying trustee) to pay
and discharge, (i) the principal of (and premium, if any, on) and each
installment of principal of (and premium, if any) and interest on the
Outstanding Securities of such series 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 the Outstanding Securities of such
series on the day on which such payments are due and payable in accordance with
the terms of this Indenture and of such Securities.

          (2) No Default or Event of Default with respect to the Securities of
such series shall have occurred and be continuing on the date of such deposit or
shall occur as a result of such deposit, and no Default or Event of Default
under clause (5) or (6) of Section 5.1 hereof shall occur and be continuing, at
any time during the period ending on the 31st day after the date of such deposit
(it being understood that this condition shall not be deemed satisfied until the
expiration of such period).

          (3) Such deposit, Defeasance or Covenant Defeasance shall not result
in a breach or violation of, or constitute a default under, any other agreement
or instrument to which the Company is a party or by which it is bound.

          (4) In the case of an election with respect to Section 13.2, the
Company shall have delivered to the Trustee either (A) a ruling directed to the
Trustee received from the Internal Revenue Service to the effect that the
Holders of the Outstanding Securities of such series 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 or (B) an Opinion of Counsel, based on a ruling published by the
Internal Revenue Service or on a change in the applicable federal income tax law
since the date of this Indenture, in either case to the effect that, and based
thereon such opinion shall confirm that, the Holders of the Outstanding
Securities of such series 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.

          (5) In the case of an election with respect to Section 13.3, the
Company shall have delivered to the Trustee an Opinion of Counsel or a ruling
directed to the Trustee received from the Internal Revenue Service to the effect
that the Holders of the Outstanding Securities of such series 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.

                                      -68-
<PAGE>
 
          (6) Such Defeasance or Covenant Defeasance shall be effected in
compliance with any additional terms, conditions or limitations which may be
imposed on the Company in connection therewith pursuant to Section 3.1.

          (7) The Company shall have delivered to the Trustee an Officer's
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for relating to either the Defeasance under Section 13.2 or
the Covenant Defeasance under Section 13.3 (as the case may be) have been
complied with.


     13.5.  Deposited Money and Government Obligations To Be Held In Trust.

     Subject to the provisions of the last paragraph of Section 10.9, all money
and Government Obligations (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee--collectively for purposes of this Section
13.5, the "Trustee") pursuant to Section 13.4 in respect of the Outstanding
Securities of a particular series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities 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 of all sums due and to become due
thereon in respect of principal (and premium, if any) and interest, but such
money need not be segregated from other funds except to the extent required by
law.

     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 13.4 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 the Outstanding Securities of such series.

     Anything in this Article to the contrary notwithstanding, the Trustee shall
deliver to pay to the Company from time to time upon Company Request any money
or Government Obligations held by it as provided in Section 13.4 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 for
the purpose for which such money or Government Obligations were deposited.

     (S) 14.1.  Miscellaneous.

which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

                                 SUBORDINATION

     (S) 15.1.  Securities Subordinated to Senior Indebtedness.

          (a) The Company covenants and agrees, and each Holder of Securities of
each series, by his acceptance thereof, likewise covenants and agrees, that
anything in this Indenture or the Securities of any series to the contrary
notwithstanding, the indebtedness evidenced by the Securities of each series is
subordinate and junior in right of payment, to the extent provided herein, to
all Senior Indebtedness, whether outstanding on the date of execution of this
Indenture or thereafter created, incurred or assumed, and that the subordination
is for the benefit of the holders of Senior Indebtedness.

          (b) Subject to Section 15.4, if (i) the Company shall default in the
payment of any principal of, premium, if any, or interest, if any, on any Senior
Indebtedness when the same becomes due and payable, whether at maturity or at a
date fixed for prepayment or by declaration of acceleration or otherwise, or
(ii) any other default shall occur with respect to Senior Indebtedness and the
maturity of such Senior Indebtedness has been accelerated in accordance with its
terms, then, upon written notice of such default to the Company and the Trustee
by the holders of Senior Indebtedness or any trustee therefor, unless and until,
in either case, the default has been cured or waived, or has ceased to exist, or
any such acceleration has been rescinded or such Senior Indebtedness has been
paid in full, no direct or indirect payment (in cash, property, securities, by
set-off or otherwise) shall be made or agreed to be made on account of the
principal of, premium, if any, or interest, if any, on any of the Securities, or
in respect of any redemption, retirement, purchase or other acquisition of any
of the Securities other than those made in capital stock of the Company (or cash
in lieu of fractional shares thereof).

          (c) If any default (other than a default described in paragraph (b) of
this Section 15.1) shall occur under the Senior Indebtedness, pursuant to which
the maturity thereof may be accelerated immediately without further notice
(except such notice as may be required to effect such acceleration) or the
expiration of any applicable grace periods occurs (a "Senior Nonmonetary
Default"), then, upon the receipt by the Company and the Trustee of written
notice thereof (a "Payment Notice") from or on

                                      -70-
<PAGE>
 
behalf of holders of such Senior Indebtedness specifying an election to prohibit
such payment and other action by the Company in accordance with the following
provisions of this paragraph (c), the Company may not make any payment or take
any other action that would be prohibited by paragraph (b) of this Section 15.1
during the period (the "Payment Blockage Period") commencing on the date of
receipt of such Payment Notice and ending on the earlier of (i) the date, if
any, on which the holders of such Senior Indebtedness or their representative
notify the Trustee that such Senior Nonmonetary Default is cured or waived or
ceases to exist or the Senior Indebtedness to which such Senior Nonmonetary
Default relates is discharged or (ii) the 179th day after the date of receipt of
such Payment Notice. Notwithstanding the provisions described in the immediately
preceding sentence, the Company may resume payments on the Securities following
such Payment Blockage Period. Any number of Payment Notices may be given;
provided, however, that (i) not more than one Payment Notice shall be given
within a period of any 360 consecutive days, and (ii) no default that existed
upon the date of such Payment Notice or the commencement of such Payment
Blockage Period (whether or not such event of default is on the same issue of
Senior Indebtedness) shall be made the basis for the commencement of any other
Payment Blockage Period.

          (d) If (i) (A) without the consent of the Company, a receiver,
conservator, liquidator or trustee of the Company or of any of its property is
appointed by the order or decree of any court or agency or supervisory authority
having jurisdiction, and such decree or order remains in effect for more than 60
days or (B) the Company is adjudicated bankrupt or insolvent or (C) any of its
property is sequestered by court order and such order remains in effect for more
than 60 days or (D) a petition is filed against the Company under any state or
federal bankruptcy, reorganization, arrangement, insolvency, readjustment of
debt, dissolution, liquidation or receivership law of any jurisdiction whether
now or hereafter in effect (including without limitation the Bankruptcy Code),
and is not dismissed within 60 days after such filing; or (ii) the Company (A)
commences a voluntary case or other proceeding seeking liquidation,
reorganization, arrangement, insolvency, readjustment of debt, dissolution,
liquidation or other relief with respect to itself or its debt or other
liabilities under any bankruptcy, insolvency or other similar law now or
hereafter in effect (including without limitation the Bankruptcy Code) or
seeking the appointment of a trustee, receiver, liquidator, custodian or other
similar official of it or any substantial part of its property, or (B) consents
to any such relief or to the appointment of or taking possession by any such
official in an involuntary case or other proceeding commenced against it, or (C)
fails generally to, or cannot, pay its debts generally as they become due or (D)
takes any corporate action to authorize or effect any of the foregoing; or (iii)
any Subsidiary of the Company takes, suffers or permits to exist any of the
events or conditions referred to in the foregoing clause (i) or (ii), then all
Senior Indebtedness (including any interest thereon accruing after the
commencement of any such proceedings) shall first be paid in full before any
payment or distribution, whether in cash, securities or other property, shall be
made to any Holder of any Securities on account thereof. Any payment or
distribution, whether in cash, securities or other property (other than
securities of the Company or any other corporation provided for by a plan of
reorganization or readjustment the payment of which is subordinate, at least to
the extent provided in these subordination provisions with respect to the
indebtedness evidenced by the Securities to the payment of all Senior
Indebtedness then outstanding and to any securities issued in respect thereof
under any such plan of reorganization or

                                      -71-
<PAGE>
 
adjustment) which would otherwise (but for these subordination provisions) be
payable or deliverable in respect of the Securities of any series shall be paid
or delivered directly to the holders of Senior Indebtedness in accordance with
the priorities then existing among such holders until all Senior Indebtedness
(including any interest thereon accruing after the commencement of any such
proceedings) shall have been paid in full. In the event of any such proceeding,
after payment in full of all sums owing with respect to Senior Indebtedness, the
Holders of the Securities, together with the holders of any obligations of the
Company ranking on a parity with the Securities, shall be entitled to be paid
from the remaining assets of the Company the amounts at the time due and owing
on account of unpaid principal of and interest, if any, on the Securities and
such other obligations before any payment or other distribution, whether in
cash, property or otherwise, shall be made on account of any capital stock or
any obligations of the Company ranking junior to the Securities and such other
obligations.

          (e) If, notwithstanding the foregoing, any payment or distribution of
any character, whether in cash, securities or other property (other than
securities of the Company or any other corporation provided for by a plan of
reorganization or readjustment the payment of which is subordinate, at least to
the extent provided in the subordination provisions with respect to the
indebtedness evidenced by the Securities, to the payment of all Senior
Indebtedness then outstanding and to any securities issued in respect thereof
under any such plan of reorganization or readjustment), shall be received by the
Trustee or any Holder in contravention of any of the terms hereof, such payment
or distribution of securities shall be received in trust for the benefit of and
shall be paid over or delivered and transferred to the holders of the Senior
Indebtedness then outstanding in accordance with the priorities then existing
among such holders for application to the payment of all Senior Indebtedness
remaining unpaid, to the extent necessary to pay all such Senior Indebtedness in
full. In the event of the failure of the Trustee or any Holder to endorse or
assign any such payment, distribution or security, each holder of such Senior
Indebtedness is hereby irrevocably authorized to endorse or assign the same.

          (f) No present or future holder of any Senior Indebtedness shall be
prejudiced in the right to enforce subordination of the indebtedness evidenced
by the Securities by any act or failure to act on the part of the Company or any
Holder of Securities. Nothing contained herein shall impair, as between the
Company and the Holders of Securities of each series, the obligation of the
Company to pay to such Holders the principal of and interest, if any, on such
Securities or prevent the Trustee or the Holder from exercising all rights,
powers and remedies otherwise permitted by applicable law or hereunder upon a
default or Event of Default hereunder, all subject to the rights of the holders
of the Senior Indebtedness to remove cash, securities or other property
otherwise payable or deliverable to the Holders.

                                      -72-
<PAGE>
 
          (g) Senior Indebtedness shall not be deemed to have been paid in full
unless the holders thereof shall have received cash, securities or other
property equal to the amount of such Senior Indebtedness then outstanding. Upon
the payment in full of all Senior Indebtedness, the Holders of Securities of
each series shall be subrogated to all rights of any holders of Senior
Indebtedness to receive any further payment or distributions applicable to the
Senior Indebtedness until the indebtedness evidenced by the Securities of such
series shall have been paid in full and such payments or distributions received
by such Holders, by reason of such subrogation, of cash, securities or other
property which otherwise would be paid or distributed to the holders of Senior
Indebtedness, shall, as between the Company and its creditors other than the
holders of Senior Indebtedness, on the one hand, and such Holders, on the other
hand, be deemed to be a payment by the Company on account of Senior
Indebtedness, and not on account of the Securities of such series.

          (h) The provisions of this Section 15.1 shall not impair any rights,
interests, remedies or powers of any secured creditor of the Company in respect
of any security interest the creation of which is not prohibited by the
provisions of this Indenture.

          (i) The securing of any obligations of the Company, otherwise ranking
on a parity with the Securities, shall not be deemed to prevent such obligations
from constituting, respectively, obligations ranking on a parity with the
Securities.


     (S) 15.2.  Reliance on Certificate of Liquidating Agent; Further Evidence
                as to Ownership of Senior Indebtedness.

          Upon any payment or distribution of assets of the Company, the Trustee
and the Holders shall be entitled to rely upon an order or decree issued by any
court of competent jurisdiction in which such dissolution or winding up or
liquidation or reorganization or arrangement proceedings are pending or upon a
certificate of the bankruptcy trustee, receiver, assignee for the benefit of
creditors or other Person making such payment or distribution, delivered to the
Trustee or to the Holders, for the purpose of ascertaining the Persons entitled
to participate in such distribution, the holders of the Senior Indebtedness and
other indebtedness of the Company, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article Fifteen.  In the absence of any such bankruptcy
trustee, receiver, assignee or other Person, the Trustee shall be entitled to
rely upon written notice by a Person representing himself to be a holder of
Senior Indebtedness (or a trustee or representative on behalf of such holder) as
evidence that such Person is a holder of Senior Indebtedness (or is such a
trustee or representative).  If the Trustee determines, in good faith, that
further evidence is required with respect to the right of any Person as a holder
of Senior Indebtedness to participate in any payment or distributions pursuant
to this Article Fifteen, the Trustee may request such Person to furnish evidence
to the reasonable satisfaction of the Trustee as to the amount of Senior
Indebtedness held by such Person, as to the extent to which such Person is
entitled to participate in such payment or

                                      -73-
<PAGE>
 
distribution, and to other facts pertinent to the rights of such Person under
this Article Fifteen, and if such evidence is not furnished, the Trustee may
defer any payment to such Person pending judicial determination as to the right
of such Person to receive such payment.

     (S) 15.3. Payment Permitted If No Default.

          Nothing contained in this Article Fifteen or elsewhere in this
Indenture, or in any of the Securities, shall prevent (a) the Company at any
time, except during the pendency of any default with respect to Senior
Indebtedness described in Section 15.1(b) or Section 15.1(c) or of any of the
events described in Section 15.1(d), from making payments of the principal of or
interest, if any, on the Securities, or (b) the application by the Trustee or
any paying agent of any moneys deposited with it hereunder to payments of the
principal of or interest, if any, on the Securities, if, at the time of such
deposit, the Trustee or such paying agent, as the case may be, did not have the
written notice provided for in Section 15.5 of any event prohibiting the making
of such deposit, or if, at the time of such deposit (whether or not in trust) by
the Company with the Trustee or paying agent (other than the Company) such
payment would not have been prohibited by the provisions of this Article
Fifteen, and the Trustee or any paying agent shall not be affected by any notice
to the contrary received by it on or after such date.

     (S) 15.4.  Disputes with Holders of Certain Senior Indebtedness.

          Any failure by the Company to make any payment on or under any Senior
Indebtedness, other than any Senior Indebtedness as to which the provisions of
this Section 15.4 shall have been waived by the Company in the instrument or
instruments by which the Company incurred, assumed, guaranteed or otherwise
created such Senior Indebtedness, shall not be deemed a default under Section
15.1 hereof if (i) the Company shall be disputing its obligation to make such
payment or perform such obligation, and (ii) either (A) no final judgment
relating to such dispute shall have been issued against the Company which is in
full force and effect and is not subject to further review, including a judgment
that has become final by reason of the expiration of the time within which a
party may seek further appeal or review, or (B) if a judgment that is subject to
further review or appeal has been issued, the Company shall in good faith be
prosecuting an appeal or other proceeding for review, and a stay of execution
shall have been obtained pending such appeal or review.

     (S) 15.5.  Trustee Not Charged with Knowledge of Prohibition.

          Anything in this Article Fifteen or elsewhere in this Indenture
contained to the contrary notwithstanding, the Trustee shall not at any time be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment of moneys to or by the Trustee and shall be entitled to
assume conclusively that no such facts exist and that no event specified in
clauses (b) and (c) of Section 15.1 has happened unless and until the Trustee
shall have received an Officers' Certificate to the effect or notice in writing
to that effect signed by or on behalf of the holder or holders, or the

                                      -74-
<PAGE>
 
representatives, of Senior Indebtedness who shall have been certified by the
Company or otherwise established to the reasonable satisfaction of the Trustee
to be such holder or holders or representatives or from any trustee under any
indenture pursuant to which such Senior Indebtedness shall be outstanding;
provided, however, that, if the Trustee shall not have received the Officers'
Certificate or notice provided for in this Section 15.5 at least three Business
Days preceding the date upon which by the terms hereof any moneys become payable
for any purpose (including, without limitation, the payment of either the
principal of or interest, if any, on any Security), then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such moneys and apply the same to the purpose for which
they were received and shall not be affected by any notice to the contrary that
may be received by it within three Business Days preceding such date.  The
Company shall give prompt written notice to the Trustee and to each paying agent
of any facts that would prohibit any payment of moneys to or by the Trustee or
any paying agent, and the Trustee shall not be charged with knowledge of the
curing of any default or the elimination of any other fact or condition
preventing such payment or distribution unless and until the Trustee shall have
received an Officers' Certificate to such effect.

     (S) 15.6.  Trustee to Effectuate Subordination.

          Each Holder of Securities by his acceptance thereof authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination as between such Holder and holders
of Senior Indebtedness as provided in this Article Fifteen and appoints the
Trustee its attorney-in-fact for any and all such purposes.

     (S) 15.7.  Rights of Trustee as Holder of Senior Indebtedness.

          The Trustee shall be entitled to all the rights set forth in this
Article Fifteen with respect to any Senior Indebtedness which may at the time be
held by it, to the same extent as any other holder of Senior Indebtedness and
nothing in this Indenture shall deprive the Trustee of any of its rights as such
holder.  Nothing in this Article Fifteen shall apply to claims of, or payments
to, the Trustee under or pursuant to Section 6.7.

     (S) 15.8.  Article Applicable to Paying Agents.

          In case at any time any paying agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article Fifteen shall in such case (unless the context shall
otherwise require) be construed as extending to and including such paying agent
within its meaning as fully for all intents and purposes as if the paying agent
were named in this Article Fifteen in addition to or in place of the Trustee;
provided, however, that Sections 15.5 and 15.7 shall not apply to the Company if
it acts as paying agent.

     (S) 15.9.  Subordination Rights Not Impaired by Acts or Omissions of the
                Company or Holders of Senior Indebtedness.

          No right of any present or future holders of any Senior Indebtedness
to enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof which any such holder may have or
be otherwise charged with.  The holders of Senior Indebtedness, may at any time
or from time to time and in their absolute direction, change the manner, place
or terms of payment, change or extend the time of payment of, or renew or alter,
any such Senior Indebtedness, or amend or supplement any instrument pursuant to
which any such Senior Indebtedness is issued or by which it may be secured, or
release any security therefor, or exercise or refrain from exercising any other
of their rights under such Senior Indebtedness, including, without limitation,
the waiver of default thereunder, all without notice to or assent from the
Holders of the Securities or the Trustee and without affecting the obligations
of the Company, the Trustee or the Holders of Securities under this Article
Fifteen.

     (S) 15.10.  Trustee Not Fiduciary for Holders of Senior Indebtedness.

          The Trustee shall not be deemed to owe any fiduciary duty to the
holders of the Senior Indebtedness, and shall not be liable to any such holders
if it shall mistakenly pay over or distribute money or assets to Securityholders
or the Company.  With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants or obligations as
are specifically set forth in this Article Fifteen and no implied covenants or
obligations with respect to holders of Senior Indebtedness shall be read into
this Indenture against the Trustee.

Re:   Adelphia Communications Corporation

Ladies and Gentlemen:

     We have acted as counsel to Adelphia Communications Corporation, a Delaware
corporation ("Adelphia" or the "Company"), in connection with the preparation of
a Registration Statement on Form S-3, File No. 333-58749 (as amended and
supplemented, the "Registration Statement"), including the form of prospectus
included therein (as supplemented, the "Prospectus"), filed by the Company with
the Securities and Exchange Commission (the "Commission") on July 9, 1998, under
the Securities Act of 1933, as amended (the "Act"), relating to the public
offering of: (i) debentures, notes and other debt securities in one or more
series (the "Debt Securities") of  Adelphia which may be senior debt securities
or subordinated debt securities of Adelphia, (ii) shares of Preferred Stock,
$.01 par value per share (the "Preferred Stock") of Adelphia issuable in series
designated by the Board of Directors of Adelphia, and (iii) shares of Class A
Common Stock, $.01 par value per share (the "Class A Common Stock") of Adelphia.
The Debt Securities, the Preferred Stock and the Class A Common Stock are
collectively referred to herein as the "Securities."  The Securities may be
offered in combination or separately from time to time by the Company in
amounts, at prices and on terms to be determined at the time or times of
offering.  The aggregate initial offering price of all of the Securities which
may be sold pursuant to the Prospectus will not exceed $750,000,000.

     This opinion is being delivered in accordance with the requirements of Item
601(b)(5) of Regulation S-K under the Act.

     In connection with this opinion, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of such documents,
certificates or records as we have deemed necessary or appropriate as bases for
the opinions set forth herein.  In our examination, we have assumed the legal
capacity of all natural persons, the genuineness of all signatures, the
authenticity of all documents submitted to us as originals, the conformity to
original documents of all documents submitted to us as certified or photostatic
copies and the authenticity of the originals of such copies.

     Based on the foregoing, and subject to the other qualifications and
limitations set forth herein, we are of the following opinion:
<PAGE>
 
          1.  When (a) the issuance, execution and delivery by the Company of
any of the Debt Securities shall have been duly authorized by all necessary
corporate actions of the Company, and (b) Debt Securities shall have been duly
executed and delivered by the Company, authenticated by the Trustee (the
"Trustee") under the indenture (the "Indenture") pursuant to which the Debt
Securities shall be issued and sold as contemplated by each of the Registration
Statement, the Prospectus, and any prospectus supplement relating to such Debt
Securities and the Indenture, assuming that the terms of such Debt Securities
are in compliance with then applicable law, such Debt Securities will be validly
issued and will constitute valid and binding obligations of the Company
enforceable against the Company in accordance with their terms, except as may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
other similar laws affecting the rights of creditors generally and by general
principles of equity and judicial discretion, including principles of commercial
reasonableness, good faith and fair dealing (whether considered in a proceeding
at law or in equity).

          2.  When (a) the terms of the issuance and sale of the Preferred Stock
shall have been duly authorized by all necessary corporate actions of the
Company, and (b) the shares of the Preferred Stock shall have been duly issued
and delivered as contemplated by each of the Registration Statement, the
Prospectus, and any prospectus supplement relating thereto and paid for with the
consideration fixed therefor by the Board of Directors or a duly authorized
committee therefor, assuming that the Company has reserved for issuance the
requisite number of shares of Preferred Stock, the Preferred Stock will be duly
authorized, validly issued, fully paid and nonassessable.

          3.  When (a) the terms of the issuance and sale of the Class A Common
Stock shall have been duly authorized by all necessary corporate actions of the
Company, and (b) the shares of Class A Common Stock shall have been duly issued
and delivered as contemplated by each of the Registration Statement, the
Prospectus, and any prospectus supplement relating thereto and paid for with the
consideration fixed therefor by the Board of Directors or a duly authorized
committee therefor, assuming that the Company has reserved for issuance the
requisite number of shares of Class A Common Stock, the Class A Common Stock
will be duly authorized, validly issued, fully paid and nonassessable.

     In rendering the above opinions, we have assumed in all cases that the
Registration Statement has been declared effective by order of the Securities
and Exchange Commission and remains in effect.  We hereby consent to the filing
of this opinion as an exhibit to the Registration Statement and the reference to
this firm under the caption "Legal Matters" in the Prospectus contained therein.
