                  Upon any application or request by the Company to the Trustee

Indenture (including any covenant compliance with which constitutes a condition
precedent) relating to the proposed action have been complied with, and an
Opinion of Counsel in a form and substance reasonably acceptable to the Trustee
stating that in the opinion of such counsel all such conditions precedent, if
any, have been complied with, except that, in the case of any such application

specifically required by any provision of this Indenture relating to such
particular application or request, no additional certificate or opinion need be
furnished.



                                      -12-
<PAGE>   23


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

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

                  (b) a brief statement as to the nature and scope of the
examination or investigation upon which the statements or opinions contained in
such certificate or opinion are based;

                  (c) a statement that, in the opinion of each such individual
or such firm, he or it has made such examination or investigation as is
necessary to enable him or it to express an informed opinion as to whether or
not such covenant or condition has been complied with; and

                  (d) a statement as to whether, in the opinion of each such
individual or such firm, such condition or covenant has been complied with.

Section 104.      FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

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

                  Any certificate of an officer of the Company or other obligor
on the Securities may be based, insofar as it relates to legal matters, upon a
certificate or opinion of, or representations by, counsel, unless such officer
knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respect to the matters upon which his
certificate or opinion is based are erroneous. Any such certificate or opinion
may be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an officer or officers of the Company or
other obligor on the Securities stating that the information with respect to
such factual matters is in the possession of the Company or other obligor on the
Securities, unless such officer or counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to such matters are erroneous. Opinions of Counsel required to be
delivered to the Trustee may have qualifications customary for opinions of the
type required and counsel delivering such Opinions of Counsel may rely on



                                      -13-
<PAGE>   24

certificates of the Company or government or other officials customary for
opinions of the type required, including certificates certifying as to matters
of fact, including that various financial covenants have been complied with.

                  Any certificate or opinion of an officer of the Company or
other obligor on the Securities may be based, insofar as it relates to
accounting matters, upon a certificate or opinion of, or representations by, an
accountant or firm of accountants in the employ of the Company, unless such
officer knows, or in the exercise of reasonable care should know, that the
certificate or opinion or representations with respect to the accounting matters
upon which his certificate or opinion may be based are erroneous. Any
certificate or opinion of any independent firm of public accountants filed with
the Trustee shall contain a statement that such firm is independent with respect
to the Company.

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

Section 105.      ACTS OF HOLDERS.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders of the Outstanding Securities of all series or one or more series, as
the case may be, may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee 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 conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Section 105.

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

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

                  (d) 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



                                      -14-
<PAGE>   25

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.

                  (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 such Holders entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other Act,
but the Company shall have no obligation to do so. Notwithstanding Trust
Indenture Act Section 316(c), any such record date shall be the record date
specified in or pursuant to such Board Resolution, which shall be a date not
more than 30 days prior to the first solicitation of Holders generally in
connection therewith and no later than the date such first solicitation is
completed.

                  If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of record at the close of
business on such record date shall be deemed to be Holders for purposes of
determining whether Holders of the requisite proportion of Securities then
Outstanding have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for this
purpose the Securities then Outstanding shall be computed as of such record
date; PROVIDED that no such request, demand, authorization, direction, notice,
consent, waiver or other Act 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 such record date.

                  (f) For purposes of this Indenture, any action by the Holders
which may be taken in writing may be taken by electronic means or as otherwise
reasonably acceptable to the Trustee.

Section 106.      NOTICES, ETC., TO THE TRUSTEE, THE 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 or any other
obligor on the Securities shall be sufficient for every purpose (except as
provided in Section 501(d), in which case, the notice shall be delivered by
certified mail) hereunder if in writing and mailed, first-class postage prepaid,
or delivered by recognized overnight courier, to or with the Trustee at its



                                      -15-
<PAGE>   26

Corporate Trust Office, Attention: Corporate Trust Trustee Administration, or at
any other address previously furnished in writing to the Holders or the Company,
or any other obligor on the Securities by the Trustee and shall be deemed given
upon actual receipt by the Trustee; or

                  (b) the Company by the Trustee or any Holder shall be
sufficient for every purpose (except as provided in Section 501(d), in which
case, the notice shall be delivered by certified mail) hereunder if in writing
and mailed, first-class postage prepaid, or delivered by recognized overnight
courier, to the Company addressed to Republic Services, Inc., 110 S.E. 6th
Street, 28th Floor, Fort Lauderdale, Florida 33301, Attention: Chief Financial
Officer, or at any other address previously furnished in writing to the Trustee
by the Company.

Section 107.      NOTICE TO HOLDERS; WAIVER.

                  Where this Indenture provides for notice to Holders of any
event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, or
delivered by recognized overnight courier, to each Holder affected by such
event, at its 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. Any notice when mailed to a Holder in the aforesaid manner shall
be conclusively deemed to have been received by such Holder whether or not
actually received by such Holder. Where this Indenture provides for notice in
any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

                  In case by reason of the suspension of regular mail service or
by reason of any other cause, it shall be impracticable to mail notice of any
event as required by any provision of this Indenture, then any method of giving
such notice as shall be reasonably satisfactory to the Trustee and reasonably
calculated to reach its destination shall be deemed to be a sufficient giving of
such notice.

Section 108.      CONFLICT WITH TRUST INDENTURE ACT.

                  If any provision hereof limits, qualifies or conflicts with
any provision of the Trust Indenture Act or another provision which is required
or deemed to be included in this Indenture by any of the provisions of the Trust
Indenture Act, the provision or requirement of the Trust Indenture Act shall
control. If any provision of this Indenture modifies or excludes any provision



                                      -16-
<PAGE>   27

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 to be
excluded, as the case may be.

Section 109.      EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

Section 110.      SUCCESSORS AND ASSIGNS.

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

Section 111.      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.

Section 112.      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, any Paying Agent and the Holders) any benefit or any legal
or equitable right, remedy or claim under this Indenture.

Section 113.      GOVERNING LAW.

                  THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING
EFFECT TO THE CONFLICT OF LAWS PRINCIPLES THEREOF.

Section 114.      LEGAL HOLIDAYS.

                  In any case where any Interest Payment Date, Redemption Date,
Maturity or Stated Maturity of any Security shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of any Security)
payment of interest or principal or premium, if any, need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on such Interest Payment Date or Redemption Date, or at
the Maturity or Stated Maturity and no interest shall accrue with respect to
such payment for the period from and after such Interest Payment Date,
Redemption Date, Maturity or Stated Maturity, as the case may be, to the next
succeeding Business Day.

Section 115.      INDEPENDENCE OF COVENANTS.

                  All covenants and agreements in this Indenture shall be given
independent effect so that if a particular action or condition is not permitted
by any such covenants, the fact that it would be permitted by an exception to,
or be otherwise within the limitations of, another covenant shall not avoid the
occurrence of a Default or an Event of Default if such action is taken or
condition exists.

Section 116.      SCHEDULES AND EXHIBITS.

                  All schedules and exhibits attached hereto are by this
reference made a part hereof with the same effect as if herein set forth in
full.

Section 117.      COUNTERPARTS.

                  This Indenture may be executed in any number of counterparts,

applicable, the Company and the Trustee, by their execution and delivery of this
Indenture, expressly agree to such terms and provisions and to be bound thereby.

         deletions from, modifications of or additions to any of the provisions
         of Section 501) of the Company with respect to Securities of the
         series, whether or not such Events of Default or covenants or other
         provisions are consistent with the Events of Default or covenants or
         other provisions set forth herein;

                  (13) the applicability, if any, of Sections 402 and 403 to the
         Securities of the series (and, in the case of Section 403, if
         applicable, any additional covenants subject to covenant defeasance)
         and any provisions in modification of, in addition to or in lieu of any
         of the provisions of Article Four;

                  (14) if the Securities of such series are to be issuable in
         definite form (whether upon original issue or upon exchange of a
         temporary Security of such series) only upon receipt of certain
         certificates or other documents or satisfaction of other conditions,
         then the form and/or terms of such certificates, documents or
         conditions;

                  (15) the terms of any temporary securities, the provisions for
         deposit and withdrawal from a common depository and terms related
         thereto;

                  (16) if the Securities of the series are to be secured or
         convertible into or exchangeable for any securities of any Person
         (including the Company), the terms and conditions upon which such
         Securities of the series will be so secured or convertible or
         exchangeable (including, without limitation, the initial conversion
         price or rate, the conversion period, the conversion agent, if any,
         adjustments of the applicable conversion price or rate and any
         requirements with respect to the reservation of shares or Securities
         for purposes of conversion);

                  (17) whether the Securities shall be bearer securities and, if
         so, any provisions related thereto;




                                      -21-
<PAGE>   32

                  (18) any other terms of the series (which terms shall not be
         inconsistent with the requirements of the Trust Indenture Act).

                  All Securities of any one series shall be substantially
identical except as to denomination and except as may otherwise by provided in
or pursuant to such Board Resolution (subject to Section 303) and set forth in
such Officers' Certificate or in any such indenture supplemental hereto. All
Securities of any one series need not be issued at the same time and, unless
otherwise provided, a series may be reopened, without the consent of the
Holders, for issuances of additional Securities of such series or to establish
additional terms of such series of Securities (which additional terms shall only
be applicable to unissued or additional Securities of such series).

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

Section 302.      DENOMINATIONS.

                  The Securities shall be issuable only in fully registered form
without coupons and only in denominations of $1,000 and any integral multiple
thereof.

Section 303.      EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

                  The Securities shall be executed on behalf of the Company by
one of its Chairman of the Board, its President, its Chief Executive Officer,
its Chief Financial Officer or one of its Vice Presidents. The signatures of any
of these officers on the Securities may be manual or facsimile.

                  Securities bearing the manual or facsimile signature of an
individual who was at any time the proper officer of the Company shall bind the
Company, notwithstanding that such individual has ceased to hold such office
prior to the authentication and delivery of such Securities or did not hold such
office 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 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 such Company Order shall authenticate and deliver such Securities as
provided in this Indenture and not otherwise.

                  Each Security shall be dated the date of its authentication.



                                      -22-
<PAGE>   33


                  No Security endorsed thereon 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 duly executed by the Trustee by manual signature of an
authorized signatory, 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.

                  Except as otherwise specified with respect to a series of
Securities in accordance with the provisions of Section 301, in case the
Company, pursuant to Article Eight, shall, in a single transaction or through a
series of related transactions, be consolidated, amalgamated, combined or merged
with or into any other Person or shall sell, assign, convey, transfer, lease or
otherwise dispose of all or substantially all of its properties and assets to
any Person, and the successor Person resulting from such consolidation,
amalgamation, or combination or surviving such merger, or into which the Company
shall have been merged, or the successor Person which shall have participated in
the sale, assignment, conveyance, transfer, lease or other disposition as
aforesaid, shall have executed an indenture supplemental hereto with the Trustee
pursuant to Article Eight, any of the Securities authenticated or delivered
prior to such consolidation, amalgamation, combination, merger, sale,
assignment, conveyance, transfer, lease or other disposition may, from time to
time, at the request of the successor Person, be exchanged for other Securities
executed in the name of the successor Person with such changes in phraseology
and form as may be appropriate, but otherwise in substance of like tenor as the
Securities surrendered for such exchange and of like principal amount; and the
Trustee, upon Company Request of the successor Person, shall authenticate and
deliver Securities as specified in such request for the purpose of such
exchange. If Securities shall at any time be authenticated and delivered in any
new name of a successor Person pursuant to this Section 303 in exchange or
substitution for or upon registration of transfer of any Securities, such
successor Person, at the option of the Holders but without expense to them,
shall provide for the exchange of all Securities at the time Outstanding for
Securities authenticated and delivered in such new name.

                  The Trustee may appoint an authenticating agent acceptable to
the Company to authenticate Securities on behalf of the Trustee. Unless limited
by the terms of such appointment, an authenticating agent may authenticate
Securities whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as any Security Registrar or Paying
Agent to deal with the Company and its Affiliates.

                  If an officer whose signature is on a Security no longer holds
that office at the time the Trustee authenticates such Security such Security
shall be valid nevertheless.

Section 304.      TEMPORARY SECURITIES.

                                      -23-
<PAGE>   34

                  (a) Pending the preparation of definitive Securities, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten 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 conclusively evidenced by
their execution of such Securities.

                  (b) If temporary Securities are issued, the Company will cause
definitive Securities to be prepared without unreasonable delay, except to
comply with applicable law. After the preparation of definitive Securities, the
temporary Securities shall be exchangeable for definitive Securities upon
surrender of the temporary Securities at the office or agency of the Company
designated for such purpose pursuant to Section 1002, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Securities,
the Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor a like principal amount of definitive Securities of authorized
denominations. Until so exchanged, the temporary Securities shall in all
respects be entitled to the same benefits under this Indenture as definitive
Securities.

                  (c) The Securities may be issued as temporary global
Securities for deposit with a Common Depository pursuant to terms set forth in a
supplemental indenture.

Section 305.      REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

                  The Company shall cause the Trustee to keep, so long as it is
the Security Registrar, at the Corporate Trust Office of the Trustee, or such
other office as the Trustee may designate, a register for each series of
Securities (the register maintained in such office or in any other office or
agency designated pursuant to Section 1002 being herein sometimes referred to as
the "Security Register") in which, subject to such reasonable regulations as the
Security Registrar may prescribe, the Company shall provide for the registration
of Securities and of transfers of Securities. The Trustee shall initially be the
"Security Registrar" for the purpose of registering Securities and transfers of
Securities as herein provided. The Company may change the Security Registrar or
appoint one or more co-Security Registrars without prior notice; PROVIDED THAT
the Company shall promptly notify the Trustee if the Company changes the
Security Registrar or appoints a co-Security Registrar.

                  Upon surrender for registration of transfer of any Security at
the office or agency of the Company designated pursuant to Section 1002, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series of any authorized denomination or denominations, of a like
aggregate principal amount.



                                      -24-
<PAGE>   35


                  Furthermore, any Holder of the Global Security shall, by
acceptance of such Global Security, agree that transfers of beneficial interests
in such Global Security may be effected only through a book-entry system
maintained by the Holder of such Global Security (or its agent), and that
ownership of a beneficial interest in a Security shall be required to be
reflected in a book entry.

                  At the option of the Holder, Securities may be exchanged for
other Securities of any authorized denomination or denominations, of a like
aggregate principal amount, 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 deliver,
Securities of the same series which the Holder making the exchange is entitled
to receive.

                  All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Company, evidencing
the same Indebtedness, 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, repurchase or redemption, 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.

                  No service charge shall be made to a Holder for any
registration of transfer, exchange or redemption of Securities, other than
exchanges pursuant to Sections 305 or 307 not involving any transfer, except for
any tax or other governmental charge that may be imposed in connection
therewith.

                  The Company shall not be required (a) to issue, register the
transfer of or exchange any Security during a period beginning at the opening of
business 15 days before the mailing of a notice of redemption of the Securities
selected for redemption under Section 1104 and ending at the close of business
on the day of such mailing or (b) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed
portion of Securities being redeemed in part.

                  Any Security authenticated and delivered upon registration of
transfer of, or in exchange for, or in lieu of, any Global Security, whether
pursuant to this Section 305, Sections 304, 306, 906 or 1108 or otherwise, shall
also be a Global Security and bear the legend specified in Exhibits A and B
hereto.

Section 306.      BOOK ENTRY PROVISIONS FOR GLOBAL SECURITIES.



                                      -25-
<PAGE>   36

                  The following provisions shall govern Global Securities except
as set forth in an indenture supplemental hereto:

                  (a) Each Global Security initially shall (i) be registered in
the name of the Depositary for such Global Security or the nominee of such
Depositary, (ii) be deposited with, or on behalf of, the Depositary or with the
Trustee as custodian for such Depositary and (iii) bear legends as set forth in
Exhibits A and B hereto.

                  Members of, or participants in, the Depositary ("Agent
Members") shall have no rights under this Indenture with respect to any Global
Security held on their behalf by the Depositary, or the Trustee as its
custodian, or under such Global Security, and the Depositary may be treated by
the Company, the Trustee and any agent of the Company or the Trustee as the
absolute owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depositary
or shall impair, as between the Depositary and its Agent Members, the operation
of customary practices governing the exercise of the rights of a holder of any
Security.

                  (b) Notwithstanding any other provision in this Indenture, no
Global Security may be exchanged in whole or in part for Securities registered,
and no transfer of a Global Security in whole or in part may be registered, in
the name of any Person other than the Depositary for such Global Security or a
nominee thereof unless (i) such Depositary (A) has notified the Company that it
is unwilling or unable to continue as Depositary for such Global Security or (B)
has ceased to be a clearing agency registered as such under the Exchange Act,
and in either case the Company fails to appoint a successor Depositary, (ii) the
Company, at its option, executes and delivers to the Trustee a Company Order
stating that it elects to cause the issuance of the Securities in certificated
form and that all Global Securities shall be exchanged in whole for Securities
that are not Global Securities (in which case, such exchange shall be effected
by the Trustee) or (iii) there shall have occurred and be continuing an Event of
Default or any Default.

                  (c) If any Global Security is to be exchanged for other
Securities or canceled in whole, it shall be surrendered by or on behalf of the
Depositary or its nominee to the Trustee, as Security Registrar, for exchange or
cancellation as provided in this Article Three. If any Global Security is to be
exchanged for other Securities or canceled in part, or if another Security is to
be exchanged in whole or in part for a beneficial interest in any Global
Security, then either (i) such Global Security shall be so surrendered for
exchange or cancellation as provided in this Article Three or (ii) the principal
amount thereof shall be reduced or increased by an amount equal to the portion
thereof to be so exchanged or canceled, or equal to the principal amount of such
other Security to be so exchanged for a beneficial interest therein, as the case
may be, by means of an appropriate adjustment made on the records of the
Trustee, as Security Registrar, whereupon the Trustee, in accordance with the
Applicable Procedures, shall instruct the Depositary or its authorized


                                      -26-
<PAGE>   37


representative to make a corresponding adjustment to its records. Upon any such
surrender or adjustment of a Global Security, the Trustee shall, subject to this
Section 306(c) and as otherwise provided in this Article Three, authenticate and
deliver any Securities issuable in exchange for such Global Security (or any
portion thereof) to or upon the order of, and registered in such names as may be
directed by, the Depositary or its authorized representative. Upon the request
of the Trustee in connection with the occurrence of any of the events specified
in the preceding paragraph, the Company shall promptly make available to the
Trustee a reasonable supply of Securities that are not in the form of Global
Securities. The Trustee shall be entitled to conclusively rely upon any order,
direction or request of the Depositary or its authorized representative which is
given or made pursuant to this Article Three if such order, direction or request
is given or made in accordance with the Applicable Procedures.

                  (d) Every Security authenticated and delivered upon
registration of transfer of, or in exchange for or in lieu of, a Global Security
or any portion thereof, whether pursuant to this Article Three or otherwise,
shall be authenticated and delivered in the form of, and shall be, a Global
Security, unless such Security is registered in the name of a Person other than
the Depositary for such Global Security or a nominee thereof.

                  (e) The Depositary or its nominee, as registered owner of a
Global Security, shall be the Holder of such Global Security for all purposes
under this Indenture and the Securities, and owners of beneficial interests in a
Global Security shall hold such interests pursuant to the Applicable Procedures.
Accordingly, any such owner's beneficial interest in a Global Security will be
shown only on, and the transfer of such interest shall be effected only through,
records maintained by the Depositary or its nominee or its Agent Members.

Section 307.      MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

                  If (a) any mutilated Security is surrendered to the Trustee,
or (b) the Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, and there is delivered to the
Company and the Trustee, such security or indemnity, in each case, as may be
required by them to save each 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 a Company Request the Trustee
shall authenticate and deliver, in exchange for any such mutilated Security or
in lieu of any such destroyed, lost or stolen Security, a replacement Security
of like tenor and principal amount, 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 replacement Security, pay or purchase such Security,
as the case may be.




                                      -27-
<PAGE>   38

                  Upon the issuance of any replacement Securities under this
Section, the Company may require the payment of a sum sufficient to pay all
documentary, stamp or similar issue or transfer taxes or other governmental
charges that may be imposed in relation thereto and any other expenses
(including the fees and expenses of the Trustee, its agents and its counsel)
connected therewith.

                  Every replacement Security 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 benefits of this Indenture equally and proportionately with any
and all other Securities 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.

Section 308.      PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

                  Except as otherwise specified with respect to a series of
Securities in accordance with the provisions of Section 301, interest on any
Security which is payable, and is punctually paid or duly provided for, on the
Stated Maturity of such interest shall be paid to the Person in whose name the
Security (or any Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest payment.

                  Except as otherwise specified with respect to a series of
Securities in accordance with the provisions of Section 301, any interest on any
Security which is payable, but is not punctually paid or duly provided for, on
the Stated Maturity of such interest, and interest on such defaulted interest at
the then applicable interest rate borne by the Securities, to the extent lawful
(such defaulted interest and interest thereon herein collectively called
"Defaulted Interest"), shall forthwith cease to be payable to the Holder on the
Regular Record Date; and such Defaulted Interest may be paid by the Company, at
its election in each case, as provided in Subsection (a) or (b) below:

                  (a) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Securities (or any relevant
         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 and the date (not less than 30 days after such
         notice) of the proposed payment (the "Special Payment Date"), 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 Special Payment Date, such money
         when deposited to be held in trust for the benefit of the Persons
         entitled to such Defaulted Interest as in this Subsection 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



                                      -28-
<PAGE>   39

         less than 10 days prior to the date of the Special Payment Date and
         shall fix the Special Record Date 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 in writing of such Special
         Record Date. In the name and at the expense of the Company, the Trustee
         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 at its 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 and Special Payment Date therefor having been so
         mailed, such Defaulted Interest shall be paid to the Persons in whose
         names the Securities are registered on such Special Record Date and
         shall no longer be payable pursuant to the following Subsection (b).

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

                  (c) Any series of Securities may provide for changes in
         interest rates or changes in spreads and any changes in redemption
         provisions in connection therewith or changes in maturity to the extent
         set forth in a supplemental Indenture with respect to such Securities.

                  Subject to the foregoing provisions of this Section 308, 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.

Section 309.      CUSIP NUMBERS.

                    The Company in issuing the Securities may use "CUSIP"
numbers (if then generally in use), and the Company, or the Trustee on behalf of
the Company, shall use CUSIP numbers in notices of redemption or exchange as a
convenience to Holders; PROVIDED, HOWEVER, that any such notice shall state that
no representation is made as to the correctness of such numbers either as
printed on the Securities or as contained in any notice of redemption or


                                      -29-
<PAGE>   40

exchange and that reliance may be placed only on the other identification
numbers printed on the Securities; and PROVIDED FURTHER, HOWEVER, that failure
to use CUSIP numbers in any notice of redemption or exchange shall not affect
the validity or sufficiency of such notice. The Company will promptly notify the
Trustee of any change in the "CUSIP" numbers.

Section 310.      PERSONS DEEMED OWNERS.

                  Prior to and at the time of 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 any Security is registered as
the owner of such Security for the purpose of receiving payment of principal of,
premium, if any, and (subject to Section 308) interest on, such Security and for
all other purposes whatsoever, whether or not such Security is overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

Section 311.      CANCELLATION.

                  All Securities surrendered for payment, purchase, redemption,
registration of transfer or exchange shall be delivered to the Trustee and, if
not already canceled, shall be promptly canceled by it. The Company may at any
time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Securities so delivered shall be promptly canceled by
the Trustee. No Securities shall be authenticated in lieu of or in exchange for
any Securities canceled as provided in this Section 311, except as expressly
permitted by this Indenture. All canceled Securities held by the Trustee shall,
upon written request of the Company, be disposed in accordance with the
Trustee's standard procedures, unless by a Company Order received by the Trustee
prior to such disposition, the Company shall direct that the canceled Securities
be returned to it. The Trustee shall provide the Company a list of all
Securities that have been canceled from time to time as requested by the
Company.

Section 312.      COMPUTATION OF INTEREST.

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

                  If pursuant to Section 301 provision is made for either or
both of (a) defeasance of the Securities of or within a series under Section 402
or (b) covenant defeasance of the Securities of or within a series under Section
403, then the provisions of such Section or Sections, as the case may be,
together with the other provisions of this Article (with such modifications
thereto as may be specified pursuant to Section 301 with respect to any
Securities), shall be applicable to such Securities, and the Company may at its
option by Board Resolution, at any time, with respect to such Securities, elect
to have Section 402 (if applicable) or Section 403 (if applicable) be applied to
such Outstanding Securities upon compliance with the conditions set forth below
in this Article.

Section 402.      DEFEASANCE AND DISCHARGE.

                  Upon the Company's exercise of the option applicable to this
Section with respect to any Securities of or within a series, the Company and
any other obligor upon the applicable series of Securities, if any, shall be
deemed to have been discharged from its obligations with respect to the Defeased
Securities on the date the conditions set forth in Section 404 below are
satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means
that the Company and any other obligor under this Indenture shall be deemed to
have paid and discharged the entire Indebtedness represented by the Defeased
Securities, which shall thereafter be deemed to be "Outstanding" only for the
purposes of Section 405 and the other Sections of this Indenture referred to in
(a) and (b) below, and to have satisfied all its other obligations under such
series of Securities and this Indenture insofar as such series of Securities are
concerned (and the Trustee, at the expense of the Company and upon Company
Request, shall execute proper instruments acknowledging the same), except for
the following which shall survive until otherwise terminated or discharged
hereunder: (a) the rights of Holders of Defeased Securities to receive, solely
from the trust fund described in Section 404 and as more fully set forth in such
Section, payments in respect of the principal of, premium, if any, and interest
on, such series of Securities, when such payments are due, (b) the Company's
obligations with respect to such Defeased Securities under Sections 303, 304,
305, 307, 1002 and 1003, (c) the rights, powers, trusts, duties and immunities
of the Trustee hereunder, including, without limitation, the Trustee's rights
under Section 607, and (d) this Article Four. Subject to compliance with this
Article Four, the Company may exercise its option under this Section 402
notwithstanding the prior exercise of its option under Section 403 with respect
to a series of Securities.

Section 403.      COVENANT DEFEASANCE.

                  Upon the Company's exercise of the option applicable to this
Section with respect to any Securities of or within a series, the Company shall
be released from its obligations under any covenant or provision contained or
referred to in Sections 1005, 1006 and 1007 and any other covenant or provision
if specified pursuant to Section 301, with respect to the Defeased Securities,
on and after the date the conditions set forth in Section 404 below are
satisfied (hereinafter, "covenant defeasance"), and the Defeased Securities



                                      -31-
<PAGE>   42

shall thereafter be deemed to be not "Outstanding" for the purposes of any
direction, waiver, consent or declaration or Act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "Outstanding" for all other purposes hereunder, and the
Events of Default under Section 501(c) and (d) and any Event of Default
specified to be covered by this Section 403 for a series in accordance with
Section 301 shall cease to be in full force and effect with respect to the
applicable series of Securities. For this purpose, such covenant defeasance
means that, with respect to the Defeased Securities, the Company may omit to
comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such Section, whether directly or indirectly, by
reason of any reference elsewhere herein to any such Section or by reason of any
reference in any such Section to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event
of Default under Section 501(c) and (d) but, except as specified above, the
remainder of this Indenture and such Defeased Securities shall be unaffected
thereby.

Section 404.      CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

                  The following shall be the conditions to application of either
Section 402 or Section 403 to the Defeased Securities of or within a series:

                  (1) The Company shall irrevocably have deposited or caused to
be deposited with the Trustee as trust funds in trust for the purpose of making
the following payments, specifically pledged as security for, and dedicated
solely to, the benefit of the Holders of such series of Securities, (a) cash in
United States dollars in an amount, (b) U.S. Government Obligations which
through the scheduled payment of principal and interest in respect thereof in
accordance with their terms and with no further reinvestment will provide, not
later than one day before the due date of payment, money in an amount, or (c) a
combination thereof, in such amounts as will be sufficient, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee to pay and discharge, the principal
of, premium, if any, and interest on, the Defeased Securities, on the Stated
Maturity of such principal or interest. For this purpose, "U.S. Government
Obligations" means securities that are (i) direct obligations of the United
States of America for the timely payment of which its full faith and credit is
pledged or (ii) obligations of a Person controlled or supervised by and acting
as an agency or instrumentality of the United States of America the timely
payment of which is unconditionally guaranteed as a full faith and credit



                                      -32-

obligation by the United States of America, which, in either case, are not
callable or redeemable at the option of the issuer thereof, and shall also
include a depository receipt issued by a bank (as defined in Section 3(a)(2) of
the Securities Act), as custodian with respect to any such U.S. Government
Obligation or a specific payment of principal of or interest on any such U.S.
Government Obligation held by such custodian for the account of the holder of
such depository receipt, PROVIDED that (except as required by law) such
custodian is not authorized to make any deduction from the amount payable to the
holder of such depository receipt from any amount received by the custodian in
respect of the U.S. Government Obligation or the specific payment of principal
of or interest on the U.S. Government Obligation evidenced by such depository
receipt;

                  (2) In the case of an election under Section 402, the Company
shall have delivered to the Trustee an Opinion of Independent Counsel in the
United States stating that (A) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling or (B) since the date
hereof, there has been a change in the applicable federal income tax law, in
either case to the effect that, and based thereon such Opinion of Independent
Counsel in the United States shall confirm that, the Holders of the Outstanding
Securities 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;

                  (3) In the case of an election under Section 403, the Company
shall have delivered to the Trustee an Opinion of Independent Counsel in the
United States to the effect that the Holders of the Outstanding Securities 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;

                  (4) No Default or Event of Default shall have occurred and be
continuing on the date of such deposit or insofar as Section 501(e) is
concerned, at any time during the period ending on the 91st day after the date
of deposit (it being understood that this condition shall not be deemed
satisfied until the expiration of such period);

                  (5) Such defeasance or covenant defeasance shall not result in
a breach or violation of, or constitute a default under, this Indenture or any
other material agreement or instrument to which the Company or any Restricted
Subsidiary is a party or by which it is bound;

                  (6) Such defeasance or covenant defeasance shall not result in
the trust arising from such deposit constituting an investment company within
the meaning of the Investment Company Act of 1940, as amended, unless such trust
shall be registered under such Act or exempt from registration thereunder;

                  (7) The Company shall have delivered to the Trustee an Opinion
of Independent Counsel in the United States to the effect that after the 91st
day following the deposit, the trust funds will not be subject to the effect of
any applicable bankruptcy, insolvency, reorganization or similar laws affecting
creditors' rights generally;



                                      -33-
<PAGE>   44


                  (8) The Company shall have delivered to the Trustee an
Officers' Certificate stating that the deposit was not made by the Company with
the intent of preferring the holders of the applicable series of Securities over
the other creditors of the Company with the intent of defeating, hindering,
delaying or defrauding creditors of the Company or others;

                  (9) No event or condition shall exist that would prevent the
Company from making payments of the principal of, premium, if any, and interest
on the applicable series of Securities on the date of such deposit or at any
time ending on the 91st day after the date of such deposit; and

                  (10) The Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Independent Counsel, each stating that
all conditions precedent provided for relating to either the defeasance under
Section 402 or the covenant defeasance under Section 403 (as the case may be)
have been complied with.

                  Opinions of Counsel or Opinions of Independent Counsel
required to be delivered under this Section shall be in form and substance
reasonably satisfactory to the Trustee and may have qualifications customary for
opinions of the type required and counsel delivering such opinions may rely on
certificates of the Company or government or other officials customary for
opinions of the type required, which certificates shall be limited as to matters
of fact, including that various financial covenants have been complied with.

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

Section 405.      DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD
                  IN TRUST; OTHER MISCELLANEOUS PROVISIONS.

                  Subject to the provisions of the last paragraph of Section
1003, all United States dollars and U.S. Government Obligations (including the
proceeds thereof) deposited with the Trustee pursuant to Section 404 in respect
of the Defeased Securities of any series shall be held in trust and applied by
the Trustee, in accordance with the provisions of such series of Securities and
this Indenture, to the payment, either directly or through any Paying Agent
(excluding the Company or any of its Affiliates acting as Paying Agent), as the
Trustee may determine, to the Holders of such series of Securities of all sums
due and to become due thereon in respect of principal, premium, if any, and
interest, but such money need not be segregated from other funds except to the
extent required by law.




                                      -34-
<PAGE>   45

                  Unless otherwise specified with respect to any Security
pursuant to Section 301, the Company shall pay and indemnify the Trustee against
any tax, fee or other charge imposed on or assessed against the U.S. Government
Obligations deposited pursuant to Section 404 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is imposed, assessed or for the account of the Holders of the Defeased
Securities.

                  Anything in this Article Four to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon Company
Request any United States dollars or U.S. Government Obligations held by it as
provided in Section 404 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect defeasance or covenant defeasance.

Section 406.      REINSTATEMENT.

                  If the Trustee or Paying Agent is unable to apply any United
States dollars or U.S. Government Obligations in accordance with Section 402 or
403, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the
applicable series of Securities shall be revived and reinstated, with present
and prospective effect, as though no deposit had occurred pursuant to Section
402 or 403, as the case may be, until such time as the Trustee or Paying Agent
is permitted to apply all such United States dollars or U.S. Government
Obligations in accordance with Section 402 or 403, as the case may be; PROVIDED,
HOWEVER, that if the Company makes any payment to the Trustee or Paying Agent of
principal of, premium, if any, or interest on any Security of such series
following the reinstatement of its obligations, the Trustee or Paying Agent
shall promptly pay any such amount to the Holders of the Securities of such
series and the Company shall be subrogated to the rights of the Holders of such
series of Securities to receive such payment from the United States dollars and
U.S. Government Obligations held by the Trustee or Paying Agent pursuant to
Section 402 or 403.

                                  ARTICLE FIVE

                  If an Event of Default (other than an Event of Default

remedied or cured by the Company or the relevant Subsidiary or waived by the
holders of the relevant Indebtedness within 60 days after the declaration of
acceleration with respect thereto.

<PAGE>   48

                  At any time after a declaration of acceleration with respect
to any of the Securities of any series, but before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the holders of a majority in principal amount of the
Outstanding Securities of any affected series (with each affected series voting

sufficient to pay

                           (i) all sums paid or advanced by the Trustee under

                           (ii) all overdue interest on all Outstanding
                  Securities of such series,

                           (iii) the principal of and premium, if any, on any
                  Outstanding Securities of such series which have become due
                  otherwise than by such declaration of acceleration and
                  interest thereon at the rate borne by such series of
                  Securities, and

                           (iv) to the extent that payment of such interest is
                  lawful, interest upon overdue interest at the rate borne by
                  the applicable series of Securities;

subsequent Default or impair any right consequent thereon.

Section 503.      COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT
                  BY TRUSTEE.

                  The Company covenants that if

                  (a) 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

                  (b) default is made in the payment of the principal of or
premium, if any, on any Security of any series at the Stated Maturity thereof or



                                      -38-
<PAGE>   49


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

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

                  If an Event of Default occurs and is continuing, the Trustee
may in its discretion proceed to protect and enforce its rights and the rights
of the Holders under this Indenture by such appropriate private or judicial
proceedings as the Trustee shall deem most effectual to protect and enforce 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 therein,
or to enforce any other proper remedy or to enforce any other proper remedy,
subject however to Section 512. No recovery of any such judgment upon any
property of the Company shall affect or impair any rights, powers or remedies of
the Trustee or the Holders.

Section 504.      TRUSTEE MAY FILE PROOFS OF CLAIM.

                  In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Company or any other obligor, upon the
Securities of any series or the property of the Company or of such other obligor
or their creditors, the Trustee (irrespective of whether the principal of such
series of 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,

                  (a) 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 of any series and to file such other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee (including any
claim for the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel) and of the Holders allowed in such judicial
proceeding, and




                                      -39-
<PAGE>   50

                  (b) 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
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 the
Trustee any amount due it for the reasonable compensation, fees and expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607.

                  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 of any series 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.

                  For purposes of this Section, the Trustee is hereby designated
as the attorney-in-fact for the Holders.

Section 505.      TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

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

Section 506.      APPLICATION OF MONEY COLLECTED.

                  Any money collected by the Trustee pursuant to this Article or
otherwise on behalf of the Holders or the Trustee pursuant to this Article or

premium, if any, or interest, upon presentation of the several Securities 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 607;

                  SECOND: To the payment of the amounts then due and unpaid upon
the Securities for principal, premium, if any, and interest, in respect of which
or for the benefit of which such money has been collected, on the Securities of
such series in the order of the maturity of the installments of such interest,
such payments to be made ratably to the Persons entitled thereto, without
preference or priority of any kind, according to the amounts due and payable on
such Securities for principal, premium, if any, and interest; and

                  THIRD: The balance, if any, to the Person or Persons entitled
thereto, including the Company, provided that all sums due and owing to the
Holders and the Trustee have been paid in full as required by this Indenture.

Section 507.      LIMITATION ON SUITS.

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

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

                  (b) the Holders of not less than 25% in aggregate 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;

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

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

                  (e) 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 the affected series;



                                      -41-
<PAGE>   52


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

Section 508.      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 based on the terms stated herein,
which is absolute and unconditional, to receive payment of the principal of,
premium, if any, and (subject to Section 308) interest on such Security on the
respective Stated Maturities expressed in such Security (or, in the case of
redemption or repurchase, on the Redemption Date or the repurchase 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.

Section 509.      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 the Company, any
other obligor on the Securities, the Trustee and the Holders shall, subject to
any determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been
instituted.

Section 510.      RIGHTS AND REMEDIES CUMULATIVE.

                  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 assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

Section 511.      DELAY OR OMISSION NOT WAIVER.

                  No delay or omission of the Trustee or of any Holder of any
Security 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



                                      -42-
<PAGE>   53


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.

Section 512.      CONTROL BY HOLDERS.

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

                  (a) such direction shall not be in conflict with any rule of
law or with this Indenture (including, without limitation, Section 507), expose
the Trustee to personal liability or be unduly prejudicial to Holders not
joining therein; and

                  (b) subject to the provisions of Section 315 of the Trust
Indenture Act, the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction.

Section 513.      WAIVER OF PAST DEFAULTS.

                  Prior to the acceleration of the maturity of any series of the
Securities, the Holders of not less than a majority in aggregate principal
amount of the Outstanding Securities of any or all series (voting separately as
a class) affected may on behalf of the Holders of all Outstanding Securities of
any such series waive any past Default or Event of Default and its consequences,
except a Default or Event of Default

                  (a) in the payment of the principal of, premium, if any, or
interest on any Security (which may only be waived with the consent of each
Holder of Securities affected); or

                  (b) in respect of a covenant or a provision hereof which under
this Indenture cannot be modified or amended without the consent of the Holder
of each Security Outstanding affected by such modification or amendment.

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

Section 514.      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



                                      -43-
<PAGE>   54

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
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the Outstanding Securities,
or to any suit instituted by any Holder for the enforcement of the payment of
the principal of, premium, if any, or interest on, any Security on or after the
respective Stated Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).

Section 515.      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 or take the benefit or advantage of, any stay or extension law
or any usury or other law wherever enacted, now or at any time hereafter in
force, which would prohibit or forgive the Company from paying all or any
portion of the principal of, premium, if any, or interest on the Securities
contemplated herein or in the Securities or which may affect the covenants or
the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

Section 516.      REMEDIES SUBJECT TO APPLICABLE LAW.

                  All rights, remedies and powers provided by this Article Five
may be exercised only to the extent that the exercise thereof does not violate
any applicable provision of law in the premises, and all the provisions of this
Indenture are intended to be subject to all applicable mandatory provisions of
law which may be controlling in the premises and to be limited to the extent
necessary so that they will not render this Indenture invalid, unenforceable or
not entitled to be recorded, registered or filed under the provisions of any
applicable law.

<PAGE>   55


                  Subject to the provisions of Trust Indenture Act Sections
315(a) through 315(d):

                  (a) if a Default or an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture and use the same degree of care and skill in its exercise
thereof as a prudent person would exercise or use under the circumstances in the
conduct of his own affairs;

                  (b) except during the continuance of a Default or an Event of
Default:

                           (1) the Trustee need perform only those duties as are
                  specifically set forth in this Indenture and no covenants or
                  obligations shall be implied in this Indenture against the
                  Trustee; and

                           (2) in the absence of bad faith or willful misconduct
                  on its part, the Trustee may conclusively rely, as to the
                  truth of the statements and the correctness of the opinions
                  expressed therein, upon certificates or opinions furnished to
                  the Trustee and conforming to the requirements of this
                  Indenture. However, the Trustee shall examine the certificates
                  and opinions which by any provision hereof are required to be
                  furnished to the Trustee, to determine whether or not they
                  conform to the requirements of this Indenture (but need not
                  confirm or investigate the accuracy of mathematical
                  calculations or other facts stated therein);

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

                           (1) this Subsection (c) does not limit the effect of
                  Subsection (b) of this Section 601;

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

                           (3) the Trustee shall not be liable with respect to
                  any action it takes or omits to take in good faith, in
                  accordance with a direction of the Holders of a majority in
                  principal amount of Outstanding Securities relating to the
                  time, method and place of conducting any proceeding for any
                  remedy available to the Trustee, or exercising any trust or
                  power confirmed upon the Trustee under this Indenture;

                  (d) no provision of this Indenture shall require the Trustee
to expend or risk its own funds or otherwise incur any financial liability in
the performance of any of its duties hereunder or in the exercise of any of its
rights or powers if it shall have reasonable grounds for believing that



                                      -45-
<PAGE>   56


repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it;

                  (e) whether or not therein expressly so provided, every
provision of this Indenture that in any way relates to the Trustee is subject to
Subsections (a), (b), (c) and (d) of this Section 601; and

                  (f) the Trustee shall not be liable for interest on any money
or assets received by it except as the Trustee may agree in writing with the
Company. Assets held in trust by the Trustee need not be segregated from other
assets except to the extent required by law.

Section 602.      NOTICE OF DEFAULTS.

                  Within 90 days after a Responsible Officer of the Trustee
receives actual notice of the occurrence of any Default, the Trustee shall
transmit by mail to all Holders and any other Persons entitled to receive
reports pursuant to Section 313(c) of the Trust Indenture Act, as their names
and addresses appear in the Security Register, notice of such Default hereunder
actually known to the Trustee, unless such Default shall have been cured or
waived; PROVIDED, HOWEVER, that, except in the case of a Default in the payment
of the principal of, premium, if any, or interest on any Security, the Trustee
shall be protected in withholding such notice if and so long as a trust
committee of Responsible Officers of the Trustee in good faith determines that
the withholding of such notice is in the interest of the Holders.

Section 603.      CERTAIN RIGHTS OF TRUSTEE.

                  Subject to the provisions of Section 601 hereof and Trust
Indenture Act Sections 315(a) through 315(d):

                  (a) the Trustee may conclusively rely and shall be protected
in acting or refraining from acting upon receipt by it of 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) the Trustee may consult with counsel of its selection and
any 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 in accordance with such
advice or Opinion of Counsel;

                  (d) 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 satisfactory to the
Trustee against the costs, expenses and liabilities which might be incurred by
it in compliance with such request or direction;




                                      -46-
<PAGE>   57

                  (e) the Trustee shall not be liable for any action taken or
omitted by it in good faith and believed by it to be authorized or within the
discretion, rights or powers conferred upon it by this Indenture other than any
liabilities arising out of the negligence, bad faith or willful misconduct of
the Trustee;

                  (f) 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, appraisal, bond, debenture, note, coupon, security or other paper or
document unless requested in writing to do so by the Holders of not less than a
majority in aggregate principal amount of the Securities then Outstanding;
PROVIDED that, if the payment within a reasonable time to the Trustee of the
costs, expenses or liabilities likely to be incurred by it in the making of such
investigation is, in the opinion of the Trustee, not reasonably assured to the
Trustee by the security afforded to it by the terms of this Indenture, the
Trustee may require reasonable indemnity against such expenses or liabilities as
a condition to proceeding; the reasonable expenses of every such investigation
so requested by the Holders of not less than 25% in aggregate principal amount
of the Securities Outstanding of an affected series shall be paid by the Company
or, if paid by the Trustee or any predecessor Trustee, shall be repaid by the
Company upon demand; PROVIDED, FURTHER, the Trustee in its discretion may make
such further inquiry or investigation into such facts or matters as it may deem
fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Company, personally or by agent or attorney;

                  (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;

                  (h) the Trustee shall not be required to take notice, and
shall not be deemed to have notice, of any Default or Event of Default
hereunder, except Events of Default described in paragraphs (a) and (b) of
Section 501 hereof unless a Responsible Officer of the Trustee shall be notified
specifically of the Default or Event of Default on a written instrument or
document received by the Trustee at its Notice Address by the Company or by the
Holders of at least 10% of the aggregate principal amount of any Securities then
outstanding and affected and such notice references the Securities and this



                                      -47-
<PAGE>   58


Indenture. In the absence of delivery of notice satisfying those requirements,
the Trustee may assume conclusively that there is no Default or Event of
Default, except as noted above;

                  (i) 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, conclusively rely upon an Officers' Certificate; and

                  (j) the rights, privileges, protections, immunities and
benefits given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each
of its capacities hereunder, and to each agent, custodian and other Person
employed by the Trustee to act hereunder.

Section 604.      TRUSTEE NOT RESPONSIBLE FOR RECITALS, DISPOSITIONS OF
                  SECURITIES OR APPLICATION OF PROCEEDS THEREOF.

                  The recitals contained herein and in the Securities, except
the Trustee's certificates of authentication, shall be taken as the statements
of the Company, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities, except that the Trustee represents that it is
duly authorized to execute and deliver this Indenture, authenticate the
Securities and perform its obligations hereunder and that the statements made by
it in any Statement of Eligibility on Form T-1 to be supplied to the Company
will be true and accurate subject to the qualifications set forth therein. The
Trustee shall not be accountable for the use or application by the Company of
Securities or the proceeds thereof.

Section 605.      TRUSTEE AND AGENTS MAY HOLD SECURITIES; COLLECTIONS; ETC.

                  The Trustee, any Paying Agent, Security Registrar or any other
agent of the Company, in its individual or any other capacity, may become the
owner or pledgee of Securities, with the same rights it would have if it were
not the Trustee, Paying Agent, Security Registrar or such other agent and,
subject to Trust Indenture Act Sections 310 and 311, may otherwise deal with the
Company and receive, collect, hold and retain collections from the Company with
the same rights it would have if it were not the Trustee, Paying Agent, Security
Registrar or such other agent.

Section 606.      MONEY HELD IN TRUST.

                  All moneys received by the Trustee shall, until used or
applied as herein provided, be held in trust for the purposes for which they
were received, but need not be segregated from other funds, except to the extent
required by mandatory provisions of law. Except for funds or securities




                                      -48-

deposited with the Trustee pursuant to Article Four, the Trustee shall be
required to invest all moneys received by the Trustee, until used or applied as
herein provided, in Temporary Cash Investments in accordance with the written
directions of the Company.

                  In the event of a loss on the sale of such investments (after
giving effect to any interest or other income thereon except to the extent
theretofore paid to the Company), the Trustee shall have no responsibility in
respect of such loss except that the Trustee shall notify the Company of the
amount of such loss and the Company shall promptly pay such amount to the
Trustee to be credited as part of the moneys originally invested.

Section 607.      COMPENSATION AND INDEMNIFICATION OF TRUSTEE AND ITS
                  PRIOR CLAIM.

                  The Company covenants and agrees to pay to the Trustee from
time to time, such compensation as agreed to in writing by the Company and the
Trustee and reasonable compensation for all other 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 all express trust), and the Company
covenants and agrees to pay or reimburse the Trustee and each predecessor
Trustee upon its request for all reasonable fees, expenses, disbursements and
advances incurred or made by or on behalf of the Trustee in accordance with any
of the provisions of this Indenture and as agreed upon in the fee agreement
between the Trustee and the Company (including the reasonable compensation and
the fees, expenses and disbursements of its counsel and of all agents and other
persons not regularly in its employ); except any such expense, disbursement or
advance as may arise from its negligence, bad faith or willful misconduct. The
Company also covenants and agrees to indemnify the Trustee and its directors,
officers, agents and employees and each predecessor Trustee (the "Indemnitees")
for, and to hold them harmless against, any claim, loss, liability, damage, tax,
assessment or other governmental charge (other than taxes applicable to the
Trustee's compensation hereunder) or expense incurred without negligence, bad
faith or willful misconduct on its part, arising out of or in connection with
the acceptance or administration of this Indenture or the trusts hereunder and
its duties hereunder, including enforcement of this Section 607 and also
including any liability which the Indemnitees may incur as a result of failure
to withhold, pay or report any tax, assessment, fine, penalty, damages or other
governmental charge, and the costs, fees and expenses of defending itself
against or investigating any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder. The obligations of the
Company under this Section 607 to compensate and indemnify the Indemnitees and
each predecessor Trustee and to pay or reimburse the Trustee and each




                                      -49-
<PAGE>   60

predecessor Trustee for reasonable fees, expenses, disbursements and advances
shall constitute an additional obligation hereunder and shall survive the
satisfaction and discharge of this Indenture and the resignation or removal of
the Trustee and each predecessor Trustee.

Section 608.      CONFLICTING INTERESTS.

                  The Trustee shall comply with the provisions of Section 310(b)
of the Trust Indenture Act.

Section 609.      TRUSTEE ELIGIBILITY.

                  There shall at all times be a Trustee hereunder which shall be
eligible to act as trustee under Trust Indenture Act Section 310(a) and which
shall have a combined capital and surplus of at least $50,000,000, to the extent
there is an institution eligible and willing to serve. If the Trustee does not
have a Corporate Trust Office in The City of New York, the Trustee may appoint
an agent in The City of New York reasonably acceptable to the Company to conduct
any activities which the Trustee may be required under this Indenture to conduct
in The City of New York. If such Trustee publishes reports of condition at least
annually, pursuant to law or to the requirements of federal, state, territorial
or District of Columbia supervising or examining authority, then for the
purposes of this Section 609, 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. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section
609, the Trustee shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

Section 610.      RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR TRUSTEE.

                  (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 under
Section 611.

                  (b) The Trustee, or any trustee or trustees hereafter
appointed, may at any time resign by giving written notice thereof to the
Company no later than 30 Business Days prior to the proposed date of
resignation. Upon receiving such notice of resignation, the Company shall
promptly appoint a successor trustee by written instrument executed by authority
of the Board of Directors of the Company, a copy of which shall be delivered to
the resigning Trustee and a copy to the successor trustee. If an instrument of
acceptance by a successor trustee shall not have been delivered to the Trustee
within 30 days after the giving of such notice of resignation, the resigning
Trustee, at the expense of the Company, or 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, may petition any court of competent jurisdiction for



                                      -50-
<PAGE>   61

the appointment of a successor trustee. Such court may thereupon, after such
notice, if any, as it may deem proper, appoint and prescribe a successor
trustee.

                  (c) The Trustee may be removed at any time for any cause or
for no cause by an Act of the Holders of not less than a majority in aggregate
principal amount of the Outstanding Securities, delivered to the Trustee and to
the Company.

                  (d) If at any time:

                           (1) the Trustee shall fail to comply with the
                  provisions of Trust Indenture Act Section 310(b) 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,

                           (2) the Trustee shall cease to be eligible under
                  Section 609 and shall fail to resign 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

                           (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 case, (i) the Company by a Board Resolution may remove the Trustee,
or (ii) subject to Section 514, the Holder of any Security who has been a bona
fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor trustee. Such
court may thereupon, after such notice, if any, as it may deem proper and
prescribe, remove the Trustee and appoint a successor trustee.

                  (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, the Company, by a Board Resolution, shall promptly appoint a
successor trustee and shall comply with the applicable requirements of Section
611. If, within 60 days after such resignation, removal or incapability, or the
occurrence of such vacancy, the Company has not appointed a successor Trustee, a
successor trustee shall be appointed by the Act of the Holders of a majority in
principal amount of the Outstanding Securities delivered to the Company and the
retiring Trustee. If no successor trustee shall have been so appointed by the
Company or the Holders of the Securities and accepted appointment in the manner
provided herein, the Trustee or the Holder of any Security who has been a bona
fide Holder of a Security of such series for at least six months may, subject to



                                      -51-
<PAGE>   62

Section 514, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor trustee
with respect to Securities of a series.

                  (f) The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor trustee by mailing
written notice of such event by first-class mail, postage prepaid, to the
Holders of Securities as their names and addresses appear in the Security
Register. Each notice shall include the name of the successor trustee and the
address of its Corporate Trust Office or agent hereunder.

Section 611.      ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

                  Every successor trustee appointed hereunder 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 as if originally named as
Trustee hereunder; but, nevertheless, on the written request of the Company or
the successor trustee, upon payment of its charges pursuant to Section 607 then
unpaid, such retiring Trustee shall pay over to the successor trustee all
moneys, Temporary Cash Investments and other property relating thereto at the
time held by it hereunder and shall execute and deliver an instrument
transferring to such successor trustee all such rights, powers, duties and
obligations. 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 and powers.

                  No successor trustee with respect to the Securities shall
accept appointment as provided in this Section 611 unless at the time of such
acceptance such successor trustee shall be eligible to act as trustee under the
provisions of Trust Indenture Act Section 310(a) and this Article Six and shall
have a combined capital and surplus of at least $50,000,000 and have a Corporate
Trust Office or an agent selected in accordance with Section 609.

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



                                      -52-
<PAGE>   63


(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 Trustee co-trustees of the
same trust and that such Trustee shall be trustee of a trust or trusts hereunder
separate and apart from any trust or trusts hereunder administered by an other
such Trustee; and upon the execution and delivery of such supplemental indenture
the resignation or removal of the retiring Trustee shall become effective to the
extent provided therein and each such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates; but, on
request of the Company or any successor Trustee, such retiring Trustee shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates.

                  Upon acceptance of appointment by any successor trustee as
provided in this Section 611, the Company shall give notice thereof to the
Holders of the Securities, by mailing such notice to such Holders at their
addresses as they shall appear on the Security Register. If the acceptance of
appointment is substantially contemporaneous with the appointment, then the
notice called for by the preceding sentence may be combined with the notice
called for by Section 610. If the Company fails to give such notice within 10
days after acceptance of appointment by the successor trustee, the successor
trustee shall cause such notice to be given at the expense of the Company.

Section 612.      MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

                  Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee (including the trust created by this
Indenture) shall be the successor of the Trustee hereunder, PROVIDED that such
corporation shall be eligible under Trust Indenture Act Section 310(a) and this
Article Six and shall have a combined capital and surplus of at least
$50,000,000 and have a Corporate Trust Office or an agent selected in accordance
with Section 609, without the execution or filing of any paper or any further
act on the part of any of the parties hereto.

                  In case at the time such successor to the Trustee shall
succeed to the trusts created by this Indenture any of the Securities shall have
been authenticated but not delivered, any such successor to the Trustee may
adopt the certificate of authentication of any predecessor Trustee and deliver
such Securities so authenticated; and, in case at that time any of the
Securities shall not have been authenticated, any successor to the Trustee may



                                      -53-
<PAGE>   64

authenticate such Securities either in the name of any predecessor hereunder or
in the name of the successor trustee; and in all such cases such certificate
shall have the full force which it is anywhere in the Securities or in this
Indenture provided that the certificate of the Trustee shall have; PROVIDED that
the right to adopt the certificate of authentication of any predecessor Trustee
or to authenticate Securities in the name of any predecessor Trustee shall apply
only to its successor or successors by merger, conversion or consolidation.

Section 613.      PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

                  If and when the Trustee shall be or become a creditor of the
Company (or other obligor under the Securities), the Trustee shall be subject to
the provisions of the Trust Indenture Act regarding the collection of claims
against the Company (or any such other obligor). A Trustee who has resigned or
been removed shall be subject to Trust Indenture Act Section 311(a) to the
extent indicated therein, as qualified by Trust Indenture Act Section 311(b).

Section 614.      APPOINTMENT OF AUTHENTICATING AGENT.

                  At any time when any of the Securities remain Outstanding, the
Trustee may appoint an Authenticating Agent or Agents with respect to one or
more series of Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities of such series issued upon exchange,
registration of transfer or partial redemption thereof, and Securities so
authenticated shall be entitled to the benefits of this Indenture and shall be
valid and obligatory for all purposes as if authenticated by the Trustee
hereunder. Any such appointment shall be evidenced by an instrument in writing
signed by a Responsible Officer of the Trustee, a copy of which instrument shall
be promptly furnished to the Company. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
reasonably acceptable to the Company and, except as may otherwise be provided
pursuant to Section 301, shall at all times be a bank or trust company or
corporation organized and doing business and in good standing under the laws of
the United States of America or of any State or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $50,000,000 and subject to supervision or
examination by Federal or State authorities. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. In case at any




                                      -54-
<PAGE>   65

time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

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

                  An Authenticating Agent for any series of Securities may at
any time resign by giving written notice of resignation to the Trustee for such
series and to the Company. The Trustee for any series of Securities may at any
time terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case of any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor
Authenticating agent which shall be acceptable to the Company and shall give
notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve in the manner set forth in
Section 106. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

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

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

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

                                             By__________________________
                                                 as Authenticating Agent

                                                 Authorized Signatory

                  (A) For the purpose of meeting any legal requirements of any
jurisdiction in which the Company may at the time be located in connection with
the enforcement of any right or the taking of any action on behalf of the
Holders of any Securities issued hereunder, the Trustee shall have the power and
may execute and deliver all instruments necessary to appoint one or more Persons
to act as a co-trustee or co-trustees, or separate trustee or separate trustees,
such powers, duties, obligations, rights and trusts as the Trustee may consider
necessary or desirable. Each co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a trustee under Section 607. The
Trustee shall promptly notify the Holders and the Company of the appointment of
a co-trustee or separate trustee under this section.

                  (B) Every separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:

                           (a) all rights, powers, duties and obligations
conferred or imposed upon the Trustee shall be conferred or imposed upon and
exercised or performed by the Trustee and such separate trustee or co-trustee
jointly (it being understood that such separate trustee or co-trustee is not
authorized to act separately without the Trustee joining in such act), except to
the extent that under any law of any jurisdiction in which any particular act or
acts are to be performed the Trustee shall be incompetent or unqualified to
perform such act or acts, in which event such rights, powers, duties and
obligations shall be exercised and performed singly by such separate trustee or
co-trustee, but solely at the direction of the Trustee;

                           (b) no trustee hereunder shall be personally liable
by reason of any act or omission of any other trustee hereunder;

                           (c) the Trustee may at any time accept the
resignation of or remove any separate trustee or co-trustee;

                           (d) any notice, request or other writing given to the
Trustee shall be deemed to have been given to each of the then separate trustees
and co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustees, as effectively as if given to




                                      -56-

each of them. Every instrument appointing any separate trustee or co-trustee
shall refer to this Indenture and the conditions of this Article Six. Each
separate trustee and co-trustee, upon its acceptance of the trusts conferred,
shall be vested with the estates or property specified in its instrument of
appointment, either jointly with the trustee or separately, as may be provided
therein, subject to all the provisions of this Indenture, specifically including
every provision of this Indenture relating to the conduct of, affecting the
liability of, or affording protection or rights (including the rights to
compensation, reimbursement and indemnification hereunder) to, the Trustee.
Every such instrument shall be filed with the Trustee; and

                           (e) any separate trustee or co-trustee may at any
time constitute the Trustee its agent or attorney-in-fact with full power and
authority, to the extent not prohibited by law, to do any lawful act under or in
respect of this Indenture on its behalf and in its name for the purposes of
enforcing any rights or taking any other action on behalf of the Holders of any
Securities issued hereunder.

                  The Trustee shall be under no obligation to analyze or make
any credit decision with respect to any financial statements or reports received

                  Delivery of such reports, information and documents to the

would result in a sale, assignment, conveyance, lease, transfer or disposition
of all or substantially all of the properties and assets of the Company and its
Restricted Subsidiaries on a Consolidated basis to any other Person or group of
Persons, unless at the time and after giving effect thereto:

                           (i) either (a) the Company will be the continuing
                  corporation in the case of a merger, combination or
                  consolidation or (b) the Person (if other than the Company)
                  formed by such consolidation or the resulting, surviving or
                  transferee Person, if other than the Company (the "Successor
                  Company",) will be a corporation duly organized and validly
                  existing under the laws of the United States of America, any
                  state thereof or the District of Columbia and such Person
                  expressly assumes, by a supplemental indenture, in a form
                  reasonably satisfactory to the Trustee, all the obligations of
                  the Company under the Securities and this Indenture, including
                  the payment of all amounts due on the Securities and the
                  performance of the covenants under this Indenture and any
                  supplemental indenture related to such Securities and in each
                  case, the Securities and the Indenture will remain in full
                  force and effect as so supplemented;

                           (ii) immediately after giving effect to such
                  transaction or series of transactions on a PRO FORMA basis,
                  including, without limitation, any Indebtedness Incurred or
                  anticipated to be Incurred in connection with or in respect of
                  such transaction or series of transactions, no Default or
                  Event of Default will have occurred and be continuing and the
                  Company will have delivered to the Trustee an Officers'
                  Certificate to that effect;

                           (iii) at the time of the transaction the Company or
                  the Successor Company will have delivered, or caused to be
                  delivered, to the Trustee, in form and substance reasonably
                  satisfactory to the Trustee, an Officers' Certificate and an
                  Opinion of Counsel, each to the effect that such transaction
                  or series of transactions, and, if a supplemental indenture is
                  required in connection with such transaction or series of
                  transactions to effectuate such assumption, such supplemental
                  indenture in respect thereof comply with this covenant and
                  that all conditions precedent in the Indenture relating to
                  such transaction have been satisfied.

                  If under the aforementioned circumstances, the Company's
properties or assets become subject to a Lien not permitted by the Indenture,
the Company will equally and ratably secure the Securities.

                  Notwithstanding the foregoing, any Restricted Subsidiary may
consolidate, amalgamate or combine with or merge with or into or, directly or
indirectly, sell, assign, convey, lease, transfer or otherwise dispose of all or
substantially all of its properties and assets to the Company or, subject to the
condition set forth in clause (ii) in the preceding sentence, to any other
Restricted Subsidiary.

duties or immunities under this Indenture or otherwise.

opinion of the Trustee and the Board of Directors, to any such supplemental
indenture may be prepared and executed by the Company and authenticated and
delivered by the Trustee in exchange for Outstanding Securities of such series.

Section 907.      NOTICE OF SUPPLEMENTAL INDENTURES.

<PAGE>   77

trust for the benefit of the Holders entitled thereto a sum sufficient to pay
the principal, premium, if any, or interest so becoming due until such sums

                  If the Company is not acting as Paying Agent, the Company will
cause each Paying Agent other than the Trustee to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section, that such Paying Agent will:

                  (a) hold all sums held by it for the payment of the principal
of, premium, if any, or interest on the Securities in trust for the benefit of
the Persons entitled thereto until such sums shall be paid to such Persons or

Company (or any other obligor upon the Securities) in the making of any payment
of principal, premium, if any, or interest on the Securities;

                  (c) 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; and

                  (d) acknowledge, accept and agree to comply in all aspects
with the provisions of this Indenture relating to the duties, rights and
liabilities of such Paying Agent.

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

                  Except as otherwise provided in the Securities of any series,

interest on any Security and remaining unclaimed for two years after such
principal and premium, if any, or interest has become due and payable shall
promptly 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 or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in the NEW YORK TIMES and THE
WALL STREET JOURNAL (national edition), and mail to each such Holder, 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 notification,
publication and mailing, any unclaimed balance of such money then remaining will
promptly be repaid to the Company.

Section 1004.     CORPORATE EXISTENCE.

                  Subject to Article Eight, the Company shall do or cause to be
done all things necessary to preserve and keep in full force and effect the
corporate existence and related rights and franchises (charter and statutory) of
the Company and each Restricted Subsidiary; provided, however, that the Company
shall not be required to preserve any such right or franchise or the corporate
existence of any such Restricted Subsidiary or any trademark, trade name or
service mark of the Company or any Restricted Subsidiary if the Board of
Directors of the Company shall determine that the preservation thereof is no
longer necessary or desirable in the conduct or the business of the Company and
its Restricted Subsidiaries taken as a whole and that the loss thereof is not
adverse in any material respect to the ability of the Company to perform its
obligations hereunder.

                  (1) the Incurrence of any Lien on any shares of stock,
Indebtedness or other obligations of a Subsidiary or any Principal Property
acquired after the date of the Indenture (including acquisitions by way of
merger or consolidation) by the Company or a Restricted Subsidiary

Securities or the Board Resolution under which any such series of Securities is
created;

                  (3) any Lien on any shares of stock, Indebtedness or other
obligations of a Subsidiary or any Principal Property in favor of the Company or
any Restricted Subsidiary;

                  (4) any Lien on Principal Property being constructed or
improved securing loans to finance such construction or improvements;

                  (5) any Lien on shares of stock, Indebtedness or other
obligations of a Subsidiary or any Principal Property Incurred in connection
with the issuance of tax exempt government obligations; and

                  (6) any renewal of or substitution for any Lien permitted by
any of the preceding clauses (1) through (5), PROVIDED, in the case of a Lien
permitted under clause (1), (2) or (4), the debt secured is not increased nor
the Lien extended to any additional assets.

                  (c) Notwithstanding the foregoing, the Company or any
Restricted Subsidiary may create or assume Liens in addition to those permitted
by clauses (1) through (6), and renew, extend or replace such Liens, provided



                                      -69-

that at the time of such creation, assumption, renewal, extension or replacement
of such Lien, and after giving effect thereto, together with any sale and
leaseback transactions permitted under Section 1006(b) hereof, Exempted Debt
does not exceed 20% of Consolidated Net Tangible Assets.

                  (d) For the purposes of this Section 1005 and Section 1006,
the giving of a guarantee which is secured by a Lien on any shares of stock,
Indebtedness or other obligations of a Subsidiary or any Principal Property, and
the creation of a Lien on any shares of stock, Indebtedness or other obligations
of a Subsidiary or any Principal Property to secure Indebtedness that existed
prior to the creation of such Lien, shall be deemed to involve the creation of
Indebtedness in an amount equal to the principal amount guaranteed or secured by
such Lien.

Section 1006.     LIMITATION ON SALE AND LEASEBACK TRANSACTIONS.

                  (a) The Company will not, and will not permit any Restricted
Subsidiary to, sell or transfer, directly or indirectly, except to the Company
or a Restricted Subsidiary, any Principal Property as an entirety, or any
substantial portion thereof, with the intention of taking back a lease of such
property, except a lease for a period of two years or less at the end of which
it is intended that the use of such property by the lessee will be discontinued;
PROVIDED that, notwithstanding the foregoing, the Company or any Restricted
Subsidiary may sell any such Principal Property and lease it back for a longer
period:

                  (1) if the Company or such Restricted Subsidiary would be
entitled, pursuant to Section 1005 hereof, to create a mortgage on the property
to be leased securing Funded Debt in an amount equal to the Attributable Debt
with respect to such sale and leaseback transaction without equally and ratably
securing the outstanding Securities; or

                  (2) if the Company promptly informs the Trustee of such
transaction, the net proceeds of such transaction are at least equal to the Fair
Market Value (as determined by Board Resolution) of such property, and the
Company causes an amount equal to the net proceeds of the sale to be applied to
the retirement, within 180 days after receipt of such proceeds, of Funded Debt
Incurred or assumed by the Company or a Restricted Subsidiary (including the
Securities); PROVIDED further that, in lieu of applying all or any part of such
net proceeds to such retirement, the Company may, within 75 days after such sale
or transfer, deliver or cause to be delivered to the applicable trustee for
cancellation either debentures or notes evidencing Funded Debt of the Company
(which may include the Outstanding Securities) or of a Restricted Subsidiary
previously authenticated and delivered by the applicable trustee, and not
theretofore tendered for sinking fund purposes or called for a sinking fund or
otherwise applied as a credit against an obligation to redeem or retire such
notes or debentures. If the Company so delivers debentures or Notes to the
applicable trustee with an Officers' Certificate, the amount of cash that the
Company will be required to apply to the retirement of Funded Debt will be
reduced by an amount equal to the aggregate of the then applicable optional
redemption prices (not including any optional sinking fund redemption prices) of
such debentures or notes, or if there are no such redemption prices, the
principal amount of such debentures or notes, provided, that in the case of
debentures or notes which provide for an amount less than the principal amount
thereof to be due and payable upon a declaration of the maturity thereof, such
amount of cash shall be reduced by the amount of principal of such debentures or
Notes that would be due and payable as of the date of such application upon a
declaration of acceleration of the maturity thereof pursuant to the terms of the
indenture pursuant to which such debentures or notes were issued; or



                                      -70-
<PAGE>   81


                  (3) if the Company, within 180 days after the sale or
transfer, applies or causes a Restricted Subsidiary to apply an amount equal to
the greater of the net proceeds of such sale or transfer or Fair Market Value of
the Principal Property so sold and leased back at the time of entering into such
sale and leaseback transaction (in either case as determined by Board Resolution
of the Company) to purchase other Principal Property having a Fair Market Value
at least equal to the Fair Market Value of the Principal Property (or portion
thereof) sold or transferred in such sale and leaseback transaction.

                  (b) Notwithstanding the foregoing, the Company or any
Restricted Subsidiary may enter into sale and leaseback transactions in addition
to those permitted in this paragraph and without any obligation to retire any
outstanding notes or other Funded Debt, provided that at the time of entering
into such sale and leaseback transactions and after giving effect thereto,
together with any Liens permitted under Section 1005(c) hereof, Exempted Debt
does not exceed 20% of Consolidated Net Tangible Assets.

Section 1007.     PROVISIONS OF FINANCIAL STATEMENTS.

                  Whether or not the Company is subject to Section 13(a) or
15(d) of the Exchange Act, the Company will, to the extent permitted under the
Exchange Act, file with the Commission the annual reports, quarterly reports and
other documents which the Company would have been required to file with the
Commission pursuant to Sections 13(a) or 15(d) if the Company was so subject,
such documents to be filed with the Commission on or prior to the date (the
"Required Filing Date") by which the Company would have been required so to file
such documents if the Company was so subject. The Company will also in any event
(x) within 15 days of each Required Filing Date (i) transmit by mail to all
holders, as their names and addresses appear in the security register, without
cost to such holders and (ii) file with the Trustee copies of the annual
reports, quarterly reports and other documents which the Company would have been
required to file with the Commission pursuant to Sections 13(a) or 15(d) of the
Exchange Act if the Company were subject to either of such Sections and (y) if
filing such documents by the Company with the Commission is not permitted under
the Exchange Act, promptly upon written request and payment of the reasonable
cost of duplication and delivery, supply copies of such documents to any
prospective holder at the Company's cost.

Section 1008.     WAIVER OF CERTAIN COVENANTS.

                  Except as specified pursuant to Section 301 for Securities of
any series, the Company may omit in any particular instance to comply with any
covenant or condition set forth in Sections 1005, 1006 and 1007 and any other
covenants specified pursuant to Section 301 if, before or after the time for
such compliance, the Holders of not less than a majority in aggregate principal
amount of the Securities at the time Outstanding of each series affected thereby
(voting as one class) shall, by Act of such Holders, waive such compliance in
such instance with such covenant or provision, but no such waiver shall extend



                                      -71-
<PAGE>   82

to or affect such covenant or condition except to the extent so expressly
waived, and, until such waiver shall become effective, the obligations of the
Company and the duties of the Trustee in respect of any such covenant or
condition shall remain in full force and effect.

                  Except as otherwise specified as contemplated by Section 301
for Securities of any series, each series of Securities will be redeemable, as a
whole or in part, at the option of the Company, at any time or from time to
time, at a Redemption Price (a "Redemption Price") equal to the greater of (i)
100% of the principal amount of the applicable series of Securities to be
redeemed and (ii) the sum of the present values of the remaining scheduled
payments of principal and interest on the applicable series of Securities
discounted to the Redemption Date (the "Redemption Date") on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at the applicable
Treasury Rate plus an amount of basis points specified in the supplemental
indenture creating such series, plus accrued interest for the Redemption Date.

Section 1102.     APPLICABILITY OF ARTICLE.

                  Redemption of Securities at the election of the Company or
otherwise, as permitted or required by any provision of this Indenture, shall be

otherwise specified as contemplated by Section 301 for Securities of any series.

Section 1103.     ELECTION TO REDEEM; NOTICE TO TRUSTEE.

                  The election of the Company to redeem any Securities shall be
evidenced by a Company Order and an Officers' Certificate. In case of any
redemption at the election of the Company, the Company shall, not less than 45
days prior to the Redemption Date fixed by the Company (unless a shorter notice
period shall be satisfactory to the Trustee), notify the Trustee in writing of
such Redemption Date and of the principal amount of the applicable series of
Securities to be redeemed except as otherwise specified as contemplated by
Section 301 for Securities of any series.

Section 1104.     SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

                  If less than all of the applicable series of Securities are to

be equal to $1,000 or any integral multiple thereof.

                  The Trustee shall promptly notify the Company and the Security
Registrar 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 redemption of Securities shall
relate, in the case of any Security redeemed or to be redeemed only in part, to
the portion of the principal amount of such Security which has been or is to be
redeemed.

Section 1105.     NOTICE OF REDEMPTION.

                  Notice of redemption shall be given by first-class mail,
postage prepaid, mailed not less than 30 days nor more than 60 days prior to the
Redemption Date unless a shorter period is specified by the terms of such series
established pursuant to Section 301, to each Holder of Securities to be
redeemed, at its address appearing in the Security Register.

                  All notices of redemption shall state:

                  (a) the Redemption Date;

                  (b) the Redemption Price;

                  (c) if less than all Outstanding Securities of a series are to
be redeemed, the identification of the particular Securities to be redeemed;

                  (d) in the case of a Security to be redeemed in part, the
principal amount of such Security to be redeemed and that after the Redemption
Date upon surrender of such Security, new Security or Securities in the
aggregate principal amount equal to the unredeemed portion thereof will be
issued;

                  (e) that Securities called for redemption must be surrendered
to the Paying Agent to collect the Redemption Price;

                  (f) that on the Redemption Date, the Redemption Price will
become due and payable upon each such Security or portion thereof to be
redeemed, and that (unless the Company shall default in payment of the
Redemption Price) interest thereon shall cease to accrue on and after said date;



                                      -73-
<PAGE>   84

                  (g) the names and addresses of the Paying Agent and the
offices or agencies referred to in Section 1002 where such Securities are to be
surrendered for payment of the Redemption Price;

                  (h) the CUSIP number, if any, relating to such Securities; and

                  (i) the procedures that a Holder must follow to surrender the
Securities to be redeemed.

                  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
written request delivered at least 15 days prior to the date such notice is to
be given (unless a shorter period shall be reasonably acceptable to the
Trustee), by the Trustee in the name and at the expense of the Company. If the
Company elects to give notice of redemption, it shall provide the Trustee with a
certificate stating that such notice has been given in compliance with the
requirements of this Section 1105.

                  The notice if mailed in the manner herein provided shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Security designated for redemption as a whole or
in part shall not affect the validity of the proceedings for the redemption of
any other Security.

Section 1106.     DEPOSIT OF REDEMPTION PRICE.

                  On or prior to 10:00 a.m. New York City time on any Redemption
Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if
the Company or any of its Affiliates is acting as Paying Agent, segregate and
hold in trust as provided in Section 1003) an amount of money in same day funds
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date or Special Payment Date) accrued interest on,
all the applicable series of Securities or portions thereof which are to be
redeemed on that date. The Paying Agent shall promptly mail or deliver to
Holders of Securities so redeemed payment in an amount equal to the Redemption
Price of the Securities purchased from each such Holder. Subject to Section
601(f), all money, if any, earned on funds held in trust by the Trustee or any

                  Notice of redemption having been given as aforesaid, the
Securities of any series 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 of such series (except as otherwise
specified pursuant to Section 301) 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



                                      -74-
<PAGE>   85


payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such on the relevant Regular Record Dates and Special
Record Dates according to the terms and the provisions of Section 308.

                  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 borne by such
Security.

Section 1108.     SECURITIES REDEEMED OR PURCHASED IN PART.

                  Any Security which is to be redeemed or purchased only in part
shall be surrendered to the Paying Agent at the office or agency maintained for
such purpose pursuant to Section 1002 (with, if the Company, the Security
Registrar or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company, the Security
Registrar or the Trustee, as the case may be, duly executed by, the Holder
thereof or such Holder's 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 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 that is not redeemed or purchased.

Indenture shall, upon Company Request, be discharged and shall cease to be of
further effect (except as to surviving rights of registration of transfer or

                  or paid as provided in Section 308 or (ii) all Securities of
                  such series for whose payment money has theretofore been
                  deposited in trust or segregated and held in trust by the
                  Company and thereafter repaid to the Company or discharged

                  delivered to the Trustee for cancellation; or

                           (2) all such Securities of such series not

                  become due and payable or, (ii) will become due and payable at
                  their Stated Maturity within one year; and the Company has
                  irrevocably deposited or caused to be deposited with the

                  firm of independent public accountants expressed in a written
                  certification thereof delivered to the Trustee) to pay and
                  discharge (without consideration of any reinvestment and after
                  payment of all taxes or other charges and assessments in
                  respect thereof payable by the Trustee) the entire
                  Indebtedness on the Securities of such series not theretofore
                  delivered to the Trustee for cancellation, including the
                  principal of, premium, if any, and accrued interest on, the
                  Securities of such series at such Maturity, Stated Maturity or
                  Redemption Date;

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

                  (c) the Company has delivered to the Trustee an Officers'

satisfactory to the Trustee, each stating that (i) all conditions precedent
herein relating to the satisfaction and discharge hereof have been complied
with, (ii) no default with respect to the Securities of such series has occurred
and is continuing on the date of such deposit and (iii) such deposit does not
result in a breach or violation of, or constitute a default under, the Indenture

to below) in aggregate principal amount to $___________, issued under and
subject to the terms of an indenture (herein called the "Indenture") dated as of
_____________, between the Company and The Bank of New York, as trustee (herein
called the "Trustee," which term includes any successor trustee under the
Indenture), to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the respective rights, limitations of rights,
duties, obligations and immunities thereunder of the Company, the Trustee and
the Holders of the Securities, and of the terms upon which the Securities are,
and are to be, authenticated and delivered.

                  The Securities may be redeemed at any time, at the option of
the Company, in whole or in part, at any time and from time to time, upon not
less than 30 and not more than 60 days' notice to the Holders thereof as
provided in the Indenture, at a Redemption Price equal to the greater of (1)
100% of the principal amount of the Securities to be redeemed and (2) the sum of
the present values of the remaining scheduled payments of principal and interest
thereon discounted to the Redemption Date on a semiannual basis (assuming a
360-day year consisting of twelve 30-day months) at the applicable Treasury
Rate, plus ___ basis points, plus, in each case, accrued interest to the
Redemption Date (subject to the right of holders of record of such Securities on
relevant record dates to receive interest due on an interest payment date), if

                  If less than all of the Securities are to be redeemed, the
Trustee shall select, not more than 60 nor less than 30 days before the
Redemption Date, the Securities or portions thereof to be redeemed on a pro rata
basis, by lot or by any other method the Trustee shall deem fair and
appropriate.

Date referred to on the face hereof. Securities (or portions thereof) for whose
redemption and payment provision is made in accordance with the Indenture shall
cease to bear interest from and after the Redemption Date.

                  In the event of redemption or repurchase of this Security in
accordance with the Indenture in part only, a new Security or Securities for the
unredeemed portion hereof shall be issued in the name of the Holder hereof upon
the cancellation hereof.

                  If an Event of Default shall occur and be continuing, the
principal amount of all the Securities may be declared due and payable in the
manner and with the effect provided in the Indenture.

                  The Indenture contains provisions for defeasance at any time
of (a) the entire Indebtedness on the Securities and (b) certain covenants and

certain amendments permitted without the consent of any Holders and certain
amendments which required the consent of all of the Holders) as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders under the Indenture and
the Securities at any time by the Company and the Trustee with the consent of
the Holders of at least a majority in aggregate principal amount of the
Securities of all series at the time Outstanding that are affected (voting as
one class). The Indenture also contains provisions permitting the Holders of at
least a majority in aggregate principal amount of the Securities (100% of the
Holders in certain circumstances) of all series at the time Outstanding that are
affected (voting as one class), on behalf of the Holders of all the Securities
of such affected series, to waive compliance by the Company with certain
provisions of the Indenture and the Securities of such series and certain past
Defaults and Events of Default under the Indenture and the Securities and their
consequences. Any such consent or waiver by or on behalf of the Holder of this
Security shall be conclusive and binding upon such Holder and upon all future
Holders of this Security and of any Security issued upon the registration of
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent or waiver is made upon this 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
or any other obligor on the Securities (in the event such other obligor is
obligated to make payments in respect of the Securities), 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.
