         existing at such time under, and pursuant to the terms of, the Credit
         Facility) will be deemed to be an Incurrence of such Indebtedness by
         the obligor not permitted by this clause (iv) and (y) any transaction
         pursuant to which any Restricted Subsidiary that has Indebtedness owing
         to the Company or any other Restricted Subsidiary ceases to be a

         Indenture (the "Original Notes"), the maximum aggregate principal
         amount of Notes would not exceed $150,000,000, provided that: (a) the

         increased proportionately by multiplying the reference to $14,000,000
         in the definition of "Floor Amount" by a fraction the numerator of
         which is the aggregate principal amount of Notes outstanding after such
         issuance and the denominator of which is the aggregate principal amount
         of Original Notes, (g) the Company and RMI enter into a supplemental
         Support Agreement, or amend the Support Agreement with the Trustee and
         Collateral Agent in order to effect such increase, (h) the Company

         Certificate attaching the express written consent of Hollinger
         International to the subordination of the International Intercompany

         issued on the Issue Date.

For purposes of determining compliance with any U.S. dollar denominated
restriction on the Incurrence of Indebtedness where the Indebtedness Incurred is
denominated in a different currency, the amount of such Indebtedness will be the
Dollar Equivalent determined on the date of the Incurrence of such Indebtedness;
provided, however, that, if any such Indebtedness denominated in a different
currency is subject to a Currency Agreement with respect to U.S. dollars
covering all principal, premium, if any, and interest payable on such
Indebtedness, the amount of such Indebtedness expressed in U.S. dollars will be
as provided in such Currency Agreement. The principal amount of any refinancing
Indebtedness Incurred in the same currency as the Indebtedness being refinanced
will be the Dollar Equivalent of the Indebtedness refinanced, except to the
extent that (i) such Dollar Equivalent was determined based on a Currency
Agreement, in which case the refinancing Indebtedness will be determined in
accordance with the preceding sentence, and (ii) the principal amount of the
refinancing Indebtedness exceeds the principal amount of the Indebtedness being
refinanced, in which case the Dollar Equivalent of such excess will be
determined on the date such refinancing Indebtedness is Incurred.

                  SECTION 1.03. Compliance Certificates and Opinions. Upon any
application or request by the Company to the Trustee to take any action under
any provision of this Indenture, the Company shall furnish to the Trustee an
Officers' Certificate to the effect that all conditions precedent, if any,
provided for in this 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 to the effect that in the opinion of
such counsel all such conditions precedent, if any, have been complied with,
except that, in the case of any such application or request as to which the
furnishing of any certificates and/or opinions is specifically required by any
provision of this Indenture relating to such particular application or request,
no additional certificate or opinion need be furnished.

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

                  (a)      a statement to the effect that each individual or
         firm signing such certificate or 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 to the effect that, in the opinion of
         each such individual or such firm, he has made such examination or
         investigation as is necessary to enable him or

                                                                              29

<PAGE>

         them 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 1.04. 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 or opinion of an Officer of the Company 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 certificate or opinion of such an Officer or of counsel 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 with respect to
such factual matters and which contains a statement to the effect that the
information with respect to such factual matters is in the possession of the
Company, unless such Officer or counsel knows 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 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.

                  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 1.05. 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 any Notes 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.

                                                                              30

<PAGE>

                  (b)      The ownership of Notes shall be proved by the Note
Register.

                  (c)      Any request, demand, authorization, direction,
notice, consent, waiver or other Act by the Holder of any Note shall bind every
future Holder of the same Note or the Holder of every Note 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 in reliance thereon, whether or not notation of such action is
made upon such Note.

                  (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 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 of 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.

                  SECTION 1.06. Notices, etc., to Trustee and 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 shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed, in writing, by first-class mail postage prepaid (return receipt
         requested) or delivered in person or by recognized overnight courier to
         or with the Trustee at its Corporate Trust Office, Attention: Corporate
         Trust Division, or at any other address furnished in writing prior
         thereto to the Holders and the Company by the Trustee; or

                  (b)      the Company, RMI or NBI shall be sufficient for every
         purpose (except as provided in Section 5.01(c)) hereunder if in writing
         and mailed, first-class postage prepaid, or delivered by recognized
         overnight courier, to the Company, addressed to it at: 10 Toronto
         Street, Toronto, Canada M5C 2B7, Attn: Chief Financial Officer, or at
         any other address previously furnished in writing to the Trustee by the
         Company, as the case may be.

                  SECTION 1.07. Notice to Holders; Waiver. Where this Indenture
or the Notes provide 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, to each Holder affected by such event,
at such Holder's address as it appears in the Note 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 or the Notes provide 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

                                                                              31

<PAGE>

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 or the Company,
as applicable, shall be deemed to be a sufficient giving of such notice.

                  SECTION 1.08. 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 of the Trust
Indenture Act that may be so modified or excluded, such provision of the Trust
Indenture Act shall be deemed to apply to this Indenture as so modified or to be
excluded, as the case may be.

                  SECTION 1.09. 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 1.10. Successors and Assigns. All covenants and
agreements in this Indenture by the Company or any Note Guarantor shall bind its
successors and assigns, whether so expressed or not.

                  SECTION 1.11. Separability Clause. In case any provision in
this Indenture or in the Notes 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 1.12. Benefits of Indenture. Nothing in this Indenture
or in the Notes, 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 1.13. GOVERNING LAW. THIS INDENTURE, THE NOTES AND THE
GUARANTEES 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 1.14. Legal Holidays. In any case where any Interest
Payment Date, Redemption Date or Stated Maturity of any Note shall not be a
Business Day, then (notwithstanding any other provision of this Indenture or of
the Notes) 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 the Interest Payment Date or Redemption Date, or
at Maturity or the 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.

                                                                              32

<PAGE>

                  SECTION 1.15. 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 1.16. Counterparts. This Indenture may be executed in
any number of counterparts, each of which shall be an original; but such
counterparts shall together constitute but one and the same instrument.

                  SECTION 1.17. Jurisdiction and Service of Process. Any legal
action or proceeding with respect to this Indenture or the Notes may be brought
in the courts of the State of New York or the federal courts of the United
States located in The City of New York, and each of the Company and the Note
Guarantors consents to the jurisdiction of such courts. Each of the Company and
the Note Guarantors irrevocably waives any objection, including any objection to
the laying of venue or based on forum non conveniens, which it may have to the
bringing of any action or proceeding in such jurisdiction with respect to this
Indenture, the Notes, the Security Agreement or any other document related
thereto. Notwithstanding the foregoing, (1) the Trustee and/or the Collateral
Agent shall have the right to bring any action or proceeding against the
Company, the Note Guarantors and their property in the courts of any other
jurisdiction the Trustee and/or the Collateral Agent deem necessary or
appropriate in order to enforce the obligations of the Company and the Note
Guarantors or to realize upon the Senior Notes Collateral or other security for
those obligations and (2) each of the Company and the Note Guarantors
acknowledges that any appeals from the courts described in the preceding
sentence may have to be heard by a court located outside those jurisdictions.

                  Each party agrees that any service of process or other legal
summons in connection with any proceeding may be served on it by mailing a copy
thereof by registered mail, or a form of mail substantially equivalent thereto,
postage prepaid, addressed to the served party at its address as provided for in
Section 1.06 hereof. Nothing in this Section shall affect the right of the
parties to serve process in any other manner permitted by law. Each of the
Company and the Note Guarantors has appointed Paul Healy at Hollinger
International Inc., 712 Fifth Avenue, 18th Floor, New York, NY 10019 as its
authorized agent in New York City (the "Authorized Agent," which term, as used
herein, includes any successor in such capacity) upon whom process may be served
in any such action, suit or proceeding arising out of or relating to this
Agreement or any of the transactions contemplated hereby which may be instituted
in any federal or state court in the State of New York by the Trustee or by any
person who controls the Trustee.

                  To the extent allowed by any applicable requirement of law,
each of the Company and the Note Guarantors waives personal service of any and
all process upon it and consents that all such service of process may be made by
registered mail (return receipt requested) directed to such party at its address
set forth in this Indenture and service so made shall be deemed to be completed
five days after the same shall have been so posted in the United States (or
Canada, as applicable), postage prepaid. Nothing contained in this Section 1.17
shall affect the right of the Trustee and/or the Collateral Agent to serve legal
process by any other manner permitted by law.

                  SECTION 1.18. Judgment Currency. If for the purpose of
obtaining judgment in any court or for the purpose of determining, pursuant to
the obligations of the Company or any Note Guarantor, the amounts owing
hereunder, it is necessary to convert an amount due

                                                                              33

<PAGE>

hereunder in U.S. dollars into a currency other than U.S. dollars (the "Judgment
Currency"), the rate of exchange applied shall be that at which, in accordance
with normal banking procedures, the Trustee or Collateral Agent could purchase,
in the New York foreign exchange market, U.S. dollars with the Judgment Currency
on the date that is two Business Days preceding that on which judgment is given
or any other payment is due hereunder. Each of the Company and the Note
Guarantors agrees that its respective obligation in respect of any U.S. dollars
due from it to the Holders hereunder shall, notwithstanding any judgment or
payment in the Judgment Currency, be discharged only to the extent that, on the
Business Day following the date the Trustee or Collateral Agent receives payment
of any sum so adjudged or owing to be due hereunder in the Judgment Currency,
the Trustee or Collateral Agent may, in accordance with normal banking
procedures, purchase, in the New York foreign exchange market U.S. dollars with
the amount of the Judgment Currency so paid; and if the amount of U.S. dollars
so purchased, or which could have been so purchased, is less than the amount
originally due in U.S. dollars, each of the Company and the Note Guarantors
agrees as a separate obligation and notwithstanding any such payment or judgment
to indemnify the Trustee or Collateral Agent against such loss. The term "rate
of exchange" in this Section 1.18 means the spot rate at which the Trustee or
Collateral Agent, in accordance with normal banking practices is able on the
relevant date to purchase U.S. dollars with the Judgment Currency and includes
any premium and costs of exchange payable in connection with such purchase.

                  No provision of this Indenture, individually or collectively,
shall have the effect of requiring the Company to pay interest (as such term is
defined in section 347 of the Criminal Code of Canada) at a rate in excess of
60% per annum, taking into account all other amounts which must be taken into
account for the purpose thereof and, to such extent, the Company's obligation to
pay interest hereunder shall be so limited.

                                  Form of Note

part of this Indenture, and, to the extent applicable, the Company, the Note
Guarantors and the Trustee, by their execution and delivery of this Indenture
expressly agree to such terms and provisions and to be bound thereby. Except as
otherwise expressly permitted in this Indenture, all Notes shall be identical in
all respects. Notwithstanding any differences among them, all Notes issued under
this Indenture shall vote and consent together on all matters as one class.

                  (c)      The Notes may have notations, legends or endorsements
as specified in Section 3.05 or as otherwise required by law, stock exchange
rule or DTC rule or usage. The Company and the Trustee shall approve the form of
the Notes and any notation, legend or endorsement on them. Each Note shall be
dated the date of its authentication.

                                                                              34

                  (d)      Notes originally offered and sold to QIBs in reliance
on Rule 144A will be issued in the form of one or more permanent Global Notes

                  (e)      Notes originally offered and sold outside the United

The Trustee's certificate of authentication shall be included on the form of the
face of the Notes substantially in the following form:

                  This is one of the Notes referred to in the within-mentioned
Indenture.

                                                NATIONAL ASSOCIATION, as Trustee

                                                By _____________________________
                                                   Authorized Signatory

                  SECTION 2.03. Form of Guarantees. (a) The form of Guarantee of
RMI shall be set forth on the Notes substantially as follows:

                     GUARANTEE OF RAVELSTON MANAGEMENT INC.

                  For value received, RAVELSTON MANAGEMENT INC., a corporation

                                    The Notes

                  SECTION 3.01. Execution, Authentication, Delivery and Dating.
(a) The Notes shall be executed on behalf of the Company by one of its Chairman
of the Board, Vice-Chairman, President or one of its Vice Presidents under its
corporate seal reproduced thereon attested by its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Notes may
be manual or facsimile.

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

                  (c)      At any time and from time to time after the execution
and delivery of this Indenture, the Company may deliver Notes executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Notes; and the Trustee in accordance with
such Company Order shall authenticate and deliver such Notes as provided in this
Indenture and not otherwise. The aggregate principal amount of Notes that may be
authenticated and delivered under this Indenture is limited to $150,000,000.

                  (d)      Each Note shall be dated the date of its
authentication.

                  (e)      No Note shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Note 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 Note shall be conclusive evidence, and
the

                                                                              36

only evidence, that such Note has been duly authenticated and delivered
hereunder and is entitled to the benefits of this Indenture.

                  (f)      In case the Company, pursuant to Article VIII, shall
be consolidated or merged with or into any other Person or shall sell, convey,
assign, transfer, lease or otherwise dispose of substantially all of its
properties and assets to any Person, and the successor Person resulting from
such consolidation, or surviving such merger, or into which the Company shall
have been merged or consolidated, or the successor Person which shall have
received a conveyance, transfer, lease or other disposition as aforesaid, shall
have executed an indenture supplemental hereto with the Trustee pursuant to
Article VIII, any of the Notes authenticated or delivered prior to such
consolidation, merger, conveyance, transfer, lease or other disposition may,
from time to time, at the request of the successor Person, be exchanged for
other Notes 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 Notes surrendered for such exchange and of like principal amount;
and the Trustee, upon a Company Request of the successor Person, shall
authenticate and deliver Notes as specified in such order for the purpose of
such exchange. If Notes shall at any time be authenticated and delivered in any
new name of a successor Person pursuant to this Section in exchange or
substitution for or upon registration of transfer of any Notes, such successor
Person, at the option of a Holder but without expense to such Holder, shall
provide for the exchange of all Notes at the time Outstanding held by such
Holder for Notes authenticated and delivered in such new name.

                  (g)      The Trustee may appoint an authenticating agent
reasonably acceptable to the Company to authenticate Notes on behalf of the
Trustee. Unless limited by the terms of such appointment, an authenticating
agent may authenticate Notes 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 Note Registrar or
Paying Agent to deal with the Company and its Affiliates.

                  SECTION 3.02. Temporary Notes. Pending the preparation of
definitive Notes, the Company may execute, and upon a Company Order the Trustee
shall authenticate and deliver, temporary Notes which are printed, lithographed,
typewritten or otherwise produced, in any authorized denomination, substantially
of the tenor of the definitive Notes in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Notes may determine, as conclusively evidenced by
their execution of such Notes.

                  If temporary Notes are issued, the Company will cause
definitive Notes to be prepared without unreasonable delay. After the
preparation of definitive Notes, the temporary Notes shall be exchangeable for
definitive Notes upon surrender of the temporary Notes at the office or agency
of the Company designated for such purpose pursuant to Section 10.02 (or in
accordance with Section 3.01, in the case of the initial Notes), without charge
to the Holders thereof. Upon surrender for cancellation of any one or more
temporary Notes, the Company shall execute and upon a Company Order the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Notes of authorized denominations. Until so exchanged the temporary
Notes shall in all respects be entitled to the same benefits under this
Indenture as definitive Notes.

                                                                              37

                  SECTION 3.03. Registration, Registration of Transfer and
Exchange. The Company shall cause to be kept at the Corporate Trust Office of
the Trustee, or such other office as the Trustee may designate, a register (the
register maintained in such office and in any other office or agency designated
pursuant to Section 10.02 being herein sometimes referred to as the "Note
Register") in which, subject to such reasonable regulations as the Note
Registrar may prescribe, the Company shall provide for the registration of Notes
and of transfers of Notes. The Trustee or an agent thereof or of the Company
shall initially be the "Note Registrar" for the purpose of registering Notes and
transfers of Notes as herein provided. The Company may appoint one or more
co-registrars, but there shall be only one Note Register.

                  Upon surrender for registration of transfer of any Note at the
office or agency of the Company designated pursuant to Section 10.02, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Notes of any
authorized denomination or denominations, of a like aggregate principal amount.

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

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

                  Every Note presented or surrendered for registration of
transfer, or for exchange 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, the Trustee and the Note
Registrar, duly executed by the Holder thereof or such Holder's attorney duly
authorized in writing.

                  No service charge shall be made to a Holder for any
registration of transfer, exchange or redemption of Notes, but the Company may
require payment of a sum sufficient to pay any tax or other governmental charges
that may be imposed in connection with any registration of transfer, exchange or
redemption of Notes (other than any such governmental charges payable upon
exchange or transfer pursuant to a Registered Exchange Offer or pursuant to
Section 3.01, 3.02, 3.07, 9.06, 10.14, 10.15 or 11.08 not involving any
transfer).

                  The Company shall not be required (a) to issue, register the
transfer of or exchange any Note during a period beginning at the opening of
business 15 days before the mailing of a notice of redemption of the Notes
selected for redemption under Section 11.04 and ending at the close of business
on the day of such mailing, or (b) to register the transfer of or exchange any
Note so selected for redemption in whole or in part, except the unredeemed
portion of Notes being redeemed in part.

                                                                              38

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

                  SECTION 3.04. Global Note Provisions (a) Each Global Note
initially shall: (i) be registered in the name of DTC or the nominee of DTC,
(ii) be delivered to the Note Custodian, and (iii) bear the appropriate legend,
as set forth in Section 3.05 and Exhibit A. Any Global Note may be represented
by more than one certificate. The aggregate principal amount of each Global Note
may from time to time be increased or decreased by adjustments made on the
records of the Note Custodian, as provided in this Indenture.

                  (b)      Members of, or participants in, DTC ("Agent Members")
shall have no rights under this Indenture with respect to any Global Note held
on their behalf by DTC or by the Note Custodian under such Global Note, and DTC
may be treated by the Company, the Trustee, the Paying Agent and the Note
Registrar and any of their agents as the absolute owner of such Global Note for
all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall
prevent the Company, the Trustee, the Paying Agent or the Note Registrar or any
of their agents from giving effect to any written certification, proxy or other
authorization furnished by DTC or impair, as between DTC and its Agent Members,
the operation of customary practices of DTC governing the exercise of the rights
of an owner of a beneficial interest in any Global Note. The registered Holder
of a Global Note may grant proxies and otherwise authorize any person, including
Agent Members and persons that may hold interests through Agent Members, to take
any action that a Holder is entitled to take under this Indenture or the Notes.

                  (c)      Except as provided below, owners of beneficial
interests in Global Notes will not be entitled to receive Certificated Notes.
Certificated Notes shall be issued to all owners of beneficial interests in a
Global Note in exchange for such interests if:

                  (i)      DTC notifies the Company that it is unwilling or
         unable to continue as depositary for such Global Note or DTC ceases to
         be a clearing agency registered under the Exchange Act, at a time when
         DTC is required to be so registered in order to act as depositary, and
         in each case a successor depositary is not appointed by the Company
         within 90 days of such notice,

                  (ii)     the Company executes and delivers to the Trustee and
         Note Registrar an Officers' Certificate stating that such Global Note
         shall be so exchangeable, or

                  (iii)    an Event of Default has occurred and is continuing
         and the Note Registrar has received a request from DTC.

In connection with the exchange of an entire Global Note for Certificated Notes
pursuant to this paragraph (c), such Global Note shall be deemed to be
surrendered to the Trustee for cancellation, and the Company shall execute, and
upon Company Order the Trustee shall authenticate and deliver, to each
beneficial owner identified by DTC in exchange for its beneficial interest in
such Global Note, an equal aggregate principal amount of Certificated Notes of
authorized denominations.

                                                                              39

<PAGE>

                  (d)      In connection with the exchange of a portion of a
Certificated Note for a beneficial interest in a Global Note, the Trustee shall
cancel such Certificated Note, and the Company shall execute, and the Trustee
shall authenticate and deliver to the exchanging Holder, a new Certificated Note
representing the principal amount not so exchanged unless such principal amount
is to be exchanged for a beneficial interest in a Global Note pursuant to
Section 3.06(d).

                  SECTION 3.05. Legends. (a) Each Global Note shall bear the
legend specified therefor in Exhibit A on the face thereof.

                  (b)      Each Restricted Note shall bear the private placement
legend specified therefor in Exhibit A on the face thereof ("Private Placement

                  SECTION 3.06. Special Transfer Provisions. (a) The following
provisions shall apply with respect to any proposed transfer of an interest in a
Rule 144A Global Note that is a Restricted Note: If (1) the owner of a
beneficial interest in a Rule 144A Global Note wishes to transfer such interest
(or portion thereof) to a non-U.S. person ("Non-U.S. Person") pursuant to

Notes through a beneficial interest in the Regulation S Global Note,

         of:

                           (A)      instructions from the Holder of the Rule

                  Registrar to credit or cause to be credited a beneficial
                  interest in the Regulation S Global Note equal to the
                  principal amount of the beneficial interest in the Rule 144A
                  Global Note to be transferred, and

                           (B)      a certificate in the form of Exhibit C from
                  the transferor, and

                  (b)      If the owner of an interest in a Regulation S Global
Note wishes to transfer such interest (or any portion thereof) to a QIB pursuant
to Rule 144A prior to the expiration of the Distribution Compliance Period
therefor,

                  (i)      upon receipt by the Note Custodian and Note Registrar

                  Registrar to credit or cause to be credited a beneficial
                  interest in the Rule 144A Global Note equal to the principal
                  amount of the beneficial interest in the Regulation S Global
                  Note to be transferred, and

                           (B)      a certificate in the form of Exhibit B duly

                  (ii)     in accordance with the rules and procedures of DTC,
         the Note Custodian and Note Registrar shall increase the Rule 144A
         Global Note and decrease the Regulation S Global Note by such amount in
         accordance with the foregoing.

                  (c)      Other Transfers. Any transfer of Restricted Notes not
described above (other than a transfer of a beneficial interest in a Global Note
that does not involve an exchange of such interest for a Certificated Note or a
beneficial interest in another Global Note, which must be effected in accordance
with applicable law and the rules and procedures of DTC, but is not subject to
any procedure required by this Indenture) shall be made only upon receipt by the
Note Registrar of such opinions of counsel, certificates and/or other
information reasonably required by and satisfactory to it in order to ensure
compliance with the Securities Act or in accordance with Section 3.06(d).

         replaced or exchanged after the Resale Restriction Termination Date
         therefor; or

                  (v)      in connection with such transfer, exchange or
         replacement the Note Registrar shall have received an Opinion of
         Counsel and other evidence reasonably satisfactory to it and the
         Company to the effect that neither such Private Placement Legend nor

Holder on or after the Resale Restriction Termination Date therefor. The Holder

                                                                              41

         member of, or a participant in, DTC or other Person with respect to the
         accuracy of the records of DTC or its nominee or of any participant or
         member thereof, with respect to any ownership interest in the Notes or
         with respect to the delivery to any participant, member, beneficial
         owner or other Person (other than DTC) of any notice (including any
         notice of redemption) or the payment of any amount or delivery of any
         Notes (or other security or property) under or with respect to such
         Notes. All notices and communications to be given to the Holders and
         all payments to be made to Holders in respect of the Notes shall be
         given or made only to or upon the order of the registered Holders
         (which shall be DTC or its nominee in the case of a Global Note). The

                                                                              42

         respect to any transfer of any interest in any Note (including any
         transfers between or among DTC participants, members or beneficial
         owners in any Global Note) other than to require delivery of such
         certificates and other documentation or evidence as are expressly
         required by, and to do so if and when expressly required by, the terms
         of this Indenture, and to examine the same to determine substantial
         compliance as to form with the express requirements hereof.

                  SECTION 3.07. Mutilated, Destroyed, Lost or Stolen Notes. If

Trustee receive evidence to their satisfaction of the destruction, loss or theft
of any Note, and there is delivered to the Company or the Trustee, such security
and/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
Note has been acquired by a bona fide purchaser, the Company shall execute and
upon receipt of a Company Order the Trustee shall authenticate and deliver, in
exchange for any such mutilated Note or in lieu of any such destroyed, lost or
stolen Note, a replacement Note of like tenor and principal amount, bearing a
number not contemporaneously outstanding.

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

                  Upon the issuance of any replacement Notes 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 charge that may
be imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee and its agents and counsel) connected therewith.

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

                  SECTION 3.08. Payment of Interest; Interest Rights Preserved.
Interest on any Note 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 that Note is registered at the close of business on the Regular
Record Date for such interest payment.

                                                                              43

<PAGE>

                  Any interest on any Note which is payable, but is not paid or
duly provided for on the Stated Maturity of such interest (or within 15 days
after the Stated Maturity of such interest) and interest on such defaulted
interest at the then applicable interest rate borne by the Notes, to the extent
lawful (such defaulted interest and interest thereon herein collectively called
"Defaulted Interest"), shall forthwith cease to be payable to the Holder in
whose name such Note is registered as of 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 Notes 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 Note and the date of
         the proposed payment (the "Special Payment Date"), and at the same time
         the Company shall irrevocably 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.
         Such notice shall be received by the Trustee no less than 30 days prior
         to the Special Payment Date. Thereupon the Trustee shall fix a Special
         Record Date for the payment of such Defaulted Interest which Special
         Record Date shall be not more than 15 days and not less than 10 days
         prior to the Special Payment Date and not less than 10 days after the
         receipt by the Trustee of the notice of the proposed payment. The
         Trustee shall promptly notify the Company 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 and Special Payment Date therefor to be
         mailed, certified or registered (return receipt requested) first-class
         postage prepaid, to each Holder at his address as it appears in the
         Note Register, not less than 10 days prior to such Special Record Date.
         Notice of the proposed payment of such Defaulted Interest and the
         Special Record Date therefor having been so mailed, such Defaulted
         Interest shall be paid to the Persons in whose names the Notes 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 to the Persons in whose
         name the Notes are registered at the close of business on the Special
         Record Date of any Defaulted Interest in any other lawful manner not
         inconsistent with the requirements of any securities exchange on which
         the Notes may be listed, and upon such notice as may be required by
         such exchange, unless, after written notice given by the Company to the
         Trustee of the proposed payment pursuant to this Subsection, such
         manner of payment shall not be deemed practicable by the Trustee
         (acting reasonably). The Trustee shall give prompt written notice to
         the Company of any such determination.

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

                                                                              44

carry the rights to interest accrued and unpaid, and to accrue, which were
carried by such other Note.

                  SECTION 3.09. Persons Deemed Owners. Prior to due presentment
of a Note 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 Note is
registered on the Note Register as the owner of such Note for the purpose of
receiving payment of principal of, premium, if any, and (subject to Section
3.08) interest on such Note and for all other purposes whatsoever, whether or
not such Note is overdue, and none of the Company, the Trustee or any agent of
the Company or the Trustee shall be affected by notice to the contrary.

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

                  SECTION 3.10. Cancellation. All Notes 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 or any Restricted Subsidiary may at any time deliver to the Trustee for
cancellation any Notes previously authenticated and delivered hereunder which
the Company or any such Restricted Subsidiary may have acquired in any manner
whatsoever, and all Notes so delivered shall upon receipt of a Company Order be
promptly canceled by the Trustee. No Notes shall be authenticated in lieu of or
in exchange for any Notes canceled as provided in this Section, except as
expressly permitted by this Indenture. All canceled securities held by the
Trustee shall, unless by a Company Order received by the Trustee prior to such
destruction the Company shall direct that the canceled Notes be returned to it,
be destroyed in accordance with its customary procedures and certification of
their destruction delivered to the Company. The Trustee shall provide the
Company a list of all Notes that have been canceled from time to time as
requested by the Company.

                  SECTION 3.11. Computation of Interest. Interest on the Notes
shall be computed on the basis of a 360-day year of twelve 30-day months.
Whenever interest to be paid hereunder is to be calculated on the basis of a
year of three hundred and sixty (360) days, the yearly rate of interest to which
the rate determined pursuant to such calculation is equivalent is the rate so
determined multiplied by the actual number of days in the calendar year in which
the same is to be ascertained and divided by three hundred and sixty (360). The
foregoing is disclosed herein solely for the purpose of providing the disclosure
required under the Interest Act (Canada).

                  SECTION 3.12. [Reserved]

                  SECTION 3.13. Additional Interest Under Registration Rights
Agreements. Under certain circumstances, the Company may be obligated to pay
additional interest to Holders, all as and to the extent set forth in the Issue
Date Registration Rights Agreement or any Registration Rights Agreement
applicable to Additional Notes. The terms thereof are hereby incorporated herein
by reference and such additional interest is deemed to be interest for purposes
of this Indenture.

                                                                              45

                                   ARTICLE IV

                       Defeasance and Covenant Defeasance

                  SECTION 4.01. Company's Option to Effect Defeasance or
Covenant Defeasance. The Company may, at its option by Board Resolution, at any
time, with respect to any Notes, elect to have either Section 4.02 or Section
4.03 be applied to all of the Outstanding Notes (the "Defeased Notes"), this
Indenture and the Security Agreement, upon compliance with the conditions set
forth below in this Article IV.

                  SECTION 4.02. Defeasance and Discharge. Upon the Company's
exercise under Section 4.01 of the option applicable to this Section, the
Company shall be deemed to have been discharged from its obligations with
respect to the Defeased Notes on the date the conditions set forth below are
satisfied (hereinafter, "defeasance") and each Note Guarantor shall be deemed to
be discharged from its obligations with respect to its Guarantee relating to the
Defeased Notes. For this purpose, such defeasance means that the Company and any
Note Guarantor shall be deemed to have paid and discharged the entire
indebtedness represented by the Defeased Notes, which shall thereafter be deemed
to be "Outstanding" only for the purposes of Section 4.05 and the other Sections
of this Indenture referred to in clauses (a) and (b) below, and to have
satisfied all its other obligations under such Notes and this Indenture insofar
as such Notes are concerned (and the Trustee, at the expense of the Company and
upon written 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 Notes to receive,
solely from the trust fund described in Section 4.04 and as more fully set forth
in such Section, payments in respect of the principal of, premium, if any, and
interest on such Notes when such payments are due, (b) the Company's obligations
with respect to such Defeased Notes under Sections 3.02, 3.03, 3.07, 10.02 and
10.03, (c) the rights, powers, trusts, duties, indemnities and immunities of the
Trustee hereunder, and (d) this Article IV. Subject to compliance with this
Article IV, the Company may exercise its option under this Section
notwithstanding the prior exercise of its option under Section 4.03 with respect
to the Notes.

                  SECTION 4.03. Covenant Defeasance. Upon the Company's exercise
under Section 4.01 of the option applicable to this Section, the Company shall
be released from its obligations under any covenant or provision contained in
Sections 10.05 through 10.18, inclusive, with respect to the Defeased Notes on
and after the date the conditions set forth below are satisfied (hereinafter,
"covenant defeasance"), and the Defeased Notes 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 and provisions, but shall continue to be deemed
"Outstanding" for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to the Defeased Notes, the Company may omit
to comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such Section or Article, whether directly or
indirectly, by reason of any reference elsewhere herein or in such Defeased
Notes to any such Section or Article or by reason of any reference in any such
Section or Article 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 5.01(c), (d) or (f) but, except as specified above, the remainder
of this Indenture and such Defeased Notes shall be unaffected thereby.

                                                                              46

                  SECTION 4.04. Conditions to Defeasance or Covenant Defeasance.
The following shall be the conditions to application of either Section 4.02 or
Section 4.03 to the Defeased Notes:

                  (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
         Notes, (a) United States dollars, (b) U.S. Government Obligations
         (which through the scheduled payment of principal and interest in
         respect thereof in accordance with their terms will provide, not later
         than one day before the due date of any payment, sufficient money), or
         (c) a combination thereof, in such amounts as will be sufficient, as
         reflected in the written report of a nationally recognized firm of
         independent public accountants or a nationally recognized investment
         banking firm 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 Notes on (x) the Stated
         Maturity thereof or (y) any date selected by the Company on which the
         Defeased Notes may be redeemed in whole at the option of the Company
         (such date being referred to as the "Defeasance Redemption Date"), if
         (in the case of clause (y)) when electing either defeasance or covenant
         defeasance, the Company has delivered to the Trustee an irrevocable
         notice to redeem all of the outstanding Notes on the Defeasance
         Redemption Date; provided that the Trustee (or such qualifying trustee)
         shall have been irrevocably instructed to apply such United States
         dollars or the proceeds of such U.S. Government obligations to said
         payments with respect to the Notes. 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 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 4.02, the
         Company shall have delivered to the Trustee an opinion of Independent
         Counsel in the United States to the effect that (A) the Company has
         received from, or there has been published by, the Internal Revenue
         Service a ruling or (B) since the date of this Indenture, there has
         been a change in the applicable Federal income tax law, in either case
         to the effect that the Holders of the Outstanding Notes 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

                                                                              47

<PAGE>

         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 4.03, 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 Notes 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)      In the case of an election under Section 4.02 and
         Section 4.03, the Company shall have delivered to the Trustee an
         opinion of Canadian counsel stating that the Company has received from,
         or there has been published by, the Canada Customs and Revenue Agency a
         ruling, in either case to the effect that, and based thereon such
         opinion shall confirm that, the Holders of the outstanding Notes will
         not recognize income, gain or loss for Canadian federal, provincial or
         territorial income tax or other tax purposes as a result of such
         deposit and defeasance and will be subject to Canadian federal,
         provincial or territorial income tax or other tax on the same amounts,
         in the same manner and at the same times as would have been the case if
         such deposit and defeasance had not occurred (and for the purposes of
         such opinion, such Canadian counsel shall assume that Holders include
         Holders who are not resident in Canada).

                  (5)      No Default or Event of Default shall have occurred
         and be continuing on the date of such deposit or insofar as Sections
         5.01(g) and 5.01(h) are concerned, at any time during the period ending
         on the 121st day after the date of deposit.

                  (6)      Any election under Section 4.02 or Section 4.03 shall
         not cause the Trustee to have a conflicting interest with respect to
         any securities of the Company.

                  (7)      Any election under Section 4.02 or Section 4.03 shall
         not result in a breach or violation of, or constitute a Default under,
         this Indenture or a breach or violation of any provision of any
         agreement relating to any Indebtedness.

                  (8)      The Company shall have delivered to the Trustee an
         Opinion of Independent Counsel in the United States to the effect that
         after the 121st 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.

                  (9)      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 over the other
         creditors of the Company or with the intent of defeating, hindering,
         delaying or defrauding creditors of the Company.

                  (10)     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 Notes on the date of such deposit or at any time
         ending on the 121st day after the date of such deposit.

                                                                              48

<PAGE>

                  (11)     The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Independent Counsel, each to
         the effect that all conditions precedent provided for relating to
         either the defeasance under Section 4.02 or the covenant defeasance
         under Section 4.03 (as the case may be) have been complied with as
         contemplated by this Section.

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

                  SECTION 4.05. 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 10.03, all United States dollars and U.S.
Government Obligations (including the proceeds thereof) deposited with the
Trustee pursuant to Section 4.04 in respect of the Defeased Notes shall be held
in trust and applied by the Trustee, in accordance with the provisions of such
Notes and this Indenture, to the payment, either directly or through any Paying
Agent as the Trustee may determine, to the Holders of such Notes 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.

                  The Company shall fully 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 4.04 or the principal and interest
received in respect thereof, other than any such tax, fee or other charge which
by law is for the account of the Holders of the Defeased Notes.

                  Anything in this Article IV to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon a Company
Request any United States dollars or U.S. Government Obligations held by it as
provided in Section 4.04 which, in the opinion of a nationally recognized firm
of independent public accountants or nationally recognized investment banking
firm expressed in a written report 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. In the event of an error in any calculation
resulting in a withdrawal hereunder, the Company shall deposit an amount equal
to the amount erroneously withdrawn as promptly as practicable after becoming
aware of such error.

                  SECTION 4.06. Reinstatement. If the Trustee or Paying Agent is
unable to apply any United States dollars or U.S. Government Obligations in
accordance with Section 4.02 or 4.03, 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 Notes shall be revived and reinstated as though no
deposit had occurred pursuant to Section 4.02 or 4.03, 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 4.02 or
4.03, as the case may be; provided, however, that (a) if the Company makes any
payment to the Trustee or Paying Agent of principal, premium, if

                                                                              49

<PAGE>

any, or interest on any Note following the reinstatement of its obligations, the
Trustee or Paying Agent shall promptly pay any such amount to the Holders of the
Notes and the Company shall be subrogated to the rights of the Holders of such
Notes to receive such payment from the United States dollars and U.S. Government
Obligations held by the Trustee or Paying Agent and (b) the Trustee or Paying
Agent shall return all such United States dollars and U.S. Government
Obligations to the Company promptly after receiving a Company Request therefor
at any time, if the Trustee or Paying Agent receives written notice from the
Company that such reinstatement of the Company's obligations has occurred and
continues to be in effect at such time.

                                    ARTICLE V

                                    Remedies

                  SECTION 5.01. Events of Default. "Event of Default", wherever
used herein, means with respect to any Notes any one of the following events
(whatever the reason for such Event of Default and whether it shall be voluntary

aggregate principal amount of the Outstanding Notes may, and the Trustee upon
the request of the Holders of not less than 25% in aggregate principal amount of

the Trustee, if given by Holders) and, if a Credit Facility is in effect, to the
relevant Agent under the Credit Facility in accordance with the terms of the

the Notes shall ipso facto become and be

                                                                              52

immediately due and payable, in an amount equal to the principal amount of the
Notes, together with accrued and unpaid interest, if any, to the date the Notes
become due and payable, without any declaration or other act on the part of the
Trustee or any Holder.

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

                  (a)      the Company has paid or irrevocably deposited with
         the Trustee a sum sufficient to pay

                           (i)      all sums paid or advanced by the Trustee
                  under Section 6.07 and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel;

                           (ii)     all overdue interest on all Notes;

                           (iii)    the principal and the premium, if any, on
                  any Notes which have become due otherwise than by such
                  declaration of acceleration and interest thereon at the rate
                  or rates presented therefor by the terms of the Notes, to the
                  extent that payment of such interest is lawful; and

                           (iv)     interest upon overdue interest at the rate
                  or rates presented therefor by the terms of the Notes, to the
                  extent that payment of such interest is lawful; and

                  (b)      all Events of Default with respect to the Notes,
         other than the nonpayment of principal of the Notes which have become
         due solely by such declaration of acceleration, have been cured or
         waived as provided in Section 5.13.

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

                  SECTION 5.03. 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
         Note 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 Note at the Stated Maturity (upon
         acceleration, optional or mandatory redemption, required repurchase or
         otherwise) thereof,

The Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Notes the whole amount then due and payable on such Notes for
principal and premium, if any, and interest, with interest upon the overdue
principal and premium, if any, and, to the extent that

                                                                              53

<PAGE>

payment of such interest shall be legally enforceable, upon overdue installments
of interest, at the rate or rates as may be presented therefor by the terms of
any such Note.

                  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 Notes and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Notes, wherever
situated.

                  If an Event of Default with respect to any Notes occurs and is
continuing, the Trustee may in its discretion proceed to protect and enforce its
rights and the rights of the Holders of Notes 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.

                  The rights and remedies under this Section are in addition to
the other rights and remedies under this Article V or Article XIII.

                  SECTION 5.04. Trustee May File Proofs of Claim. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other similar judicial
proceeding relative to the Company or the property of the Company, the Trustee
(irrespective of whether the principal of the Notes 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 Notes 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

                  (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, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 6.07.

                  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, composition or other
similar arrangement affecting the Notes or the rights of any

                                                                              54

Holder thereof, or to authorize the Trustee to vote in respect of the claim of
any Holder in any such proceeding.

Notes. All rights of action and claims under this Indenture or the Notes may be
prosecuted and enforced by the Trustee without the possession of any of the
Notes 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, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Notes in respect of which such judgment has been recovered.

                  SECTION 5.06. Application of Money Collected. Any money
collected by the Trustee with respect to the Notes pursuant to this Article or
otherwise on behalf of the Holders or the Trustee pursuant to this Article or
through any proceeding or any arrangement or restructuring in anticipation or in
lieu of any proceeding contemplated by this Article shall be applied, subject to
applicable law, in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal,

         according to the amounts due and payable on such Notes for principal,
         premium, if any, and interest; and

                  THIRD: The balance, if any, to the Person or Persons entitled
         thereto as a court of competent jurisdiction shall direct, or to 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 5.07. Limitation on Suits. No Holder of any Notes
shall have any right to institute any proceeding, judicial or otherwise, with
respect to this Indenture or the Notes, 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 Notes;

                  (b)      the Holders of not less than 25% in principal amount
         of the outstanding Notes 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, and if requested
         have provided, to the Trustee an indemnity satisfactory to the Trustee
         in its sole discretion against the costs, expenses and liabilities that
         may be incurred in compliance with such request;

                                                                              55

<PAGE>

                  (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 Notes;

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

                  SECTION 5.08. Unconditional Right of Holders to Receive
Principal, Premium and Interest. Notwithstanding any other provision in this
Indenture, the Holder of any Note shall have the right on the terms stated

respective Stated Maturities expressed in such Note (or, in the case of
redemption, on the Redemption Date) and to institute suit for the enforcement of
any such payment, and such rights shall not be impaired without the consent of
such Holder.

                  SECTION 5.09. Restoration of Rights and Remedies. If the
Trustee or any Holder has instituted any proceeding to enforce any right or
remedy under this Indenture and such proceeding has been discontinued or
abandoned for any reason, or has been determined adversely to the Trustee or to
such Holder, then and in every such case, subject to any determination in such
proceeding, (a) the Company, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder, and (b)

provided in Section 3.07, 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 5.11. Delay or Omission Not Waiver. No delay or
omission of the Trustee or of any Holder of any Note to exercise any right or
remedy accruing upon any Event of Default shall impair any such right or remedy
or constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders, as the case may be.

                                                                              56

a majority in aggregate principal amount of the Outstanding Notes shall have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee; provided that:

                  (a)      such direction shall not be in conflict with any rule
         of law or with this Indenture (including, without limitation, Section
         5.07) or expose the Trustee to personal liability; 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 5.13. Waiver of Past Defaults. The Holders of not less
than a majority in aggregate principal amount of the Outstanding Notes may on
behalf of the Holders of all the Notes waive any past Default hereunder and its
consequences, except a Default

                  (a)      in the payment of the principal of, premium, if any,
         or interest on any Notes, or

                  (b)      in respect of a covenant or provision hereof which
         under Article IX cannot be modified or amended without the consent of
         the Holder of each Outstanding Note 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 5.14. Undertaking for Costs. All parties to this
Indenture agree, and each Holder of any Note by his acceptance thereof shall be
deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken, suffered or omitted by it as Trustee,
the filing by any party litigant in such suit of an undertaking to pay the costs
of such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but the provisions of this Section shall not apply to any
suit instituted by the 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 Notes to which the suit relates, 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 Note on or after the respective Stated Maturities expressed
in such Note (or, in the case of redemption, on or after the Redemption Date).

                  SECTION 5.15. Waiver of Stay, Extension or Usury Laws. The
Company (to the extent that it may lawfully do so) covenants 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 similar
law wherever enacted, now or at any time hereafter in force, which

                                                                              57

would prohibit or forgive the Company from paying all or any portion of the
principal of, premium, if any, or interest on the Notes contemplated herein or
in the Notes 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 5.16. Remedies Subject to Applicable Law. All rights,
remedies and powers provided by this Article 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.

                                   ARTICLE VI

                                   The Trustee

                  SECTION 6.01. Duties of Trustee. (a) If a Default or an Event
of Default with respect to any Notes actually known to the Trustee 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. The Trustee shall not be
charged with knowledge of any Default or Event of Default with respect to any
Notes, Asset Sale or Change of Control unless written notice thereof shall have
been delivered to a Responsible Officer by the Company or any other Person.

                  (b)      Except during the continuance of a Default or an
Event of Default with respect to any Notes actually known to the Trustee:

                  (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 that are adverse to the
         Trustee; and

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

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

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

                                                                              58

<PAGE>

                  (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 Notes 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 loss, expense,
fees or financial liability in the performance of any of its duties hereunder or
in the exercise of any of its rights or powers if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or loss, expense, fees or financial 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
paragraphs (a), (b), (c) and (d) of this Section.

                  (f)      The Trustee shall not be liable for interest on any
money or assets received by it except as the Trustee may agree 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 6.02. Notice of Defaults. Within 30 days after a
Responsible Officer of the Trustee receives notice of the occurrence of any
Default with respect to any Notes, the Trustee shall, at the Company's expense,
transmit by mail to all Holders of such Notes or any other persons entitled to
receive reports pursuant to Trust Indenture Act Section 313(c), as their names
and addresses appear in the Note Register, notice of such Default, 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 Note, the Trustee shall be protected in withholding such notice
if and so long as a Responsible Officer of the Trustee in good faith determines
that the withholding of such notice is in the interest of the Holders of such
Notes.

                  SECTION 6.03. Certain Rights of Trustee. Subject to the
provisions of Trust Indenture Act Sections 315(a) through 315(d):

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

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

                                                                              59

<PAGE>

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

                  (d)      the Trustee may consult with counsel and any written
         advice of such counsel or any Opinion of Counsel shall be full and
         complete authorization and protection in respect of any action taken,
         suffered or omitted by it hereunder in good faith and in reliance
         thereon in accordance with such advice or Opinion of Counsel;

                  (e)      notwithstanding any other provisions contained in
         this Indenture, 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 in its sole discretion against
         the costs, expenses and liabilities which might be incurred therein or
         thereby in compliance with such request or direction;

                  (f)      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 or
         wilful misconduct of the Trustee;

                  (g)      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; but the Trustee in its
         discretion may make such further inquiry or investigation in accordance
         with any of the provisions of this Indenture into such facts or matters
         as it may see fit, and, if the Trustee shall determine to make such
         further inquiry or investigation, it shall be entitled to examine such
         relevant books, records and premises of the Company as may be
         reasonable, personally or by agent or attorney;

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

                  (i)      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 and powers.

                  SECTION 6.04. Trustee Not Responsible for Recitals,
Dispositions of Notes or Application of Proceeds Thereof. The recitals contained
herein and in the Notes, 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 the Notes, except that the
Trustee represents that

                                                                              60

<PAGE>

it is duly authorized to execute and deliver this Indenture, authenticate the
Notes and perform its obligations hereunder and that the statements made by it
in a Statement of Eligibility and Qualification on Form T-1 supplied to the
Company are 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 Notes or the proceeds thereof.

                  SECTION 6.05. Trustee and Agents May Hold Notes; Collections;
etc. The Trustee, any Paying Agent, Note Registrar or any other agent of the
Company, in its individual or any other capacity, may become the owner or
pledgee of Notes, with the same rights it would have if it were not the Trustee,
Paying Agent, Note 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, Note Registrar or such
other agent.

                  SECTION 6.06. 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 deposited with the Trustee pursuant to Article IV, the
Trustee shall only be required to invest moneys received by the Trustee, until
used or applied as herein provided, in Temporary Cash Investments in accordance
with the directions of the Company.

                  SECTION 6.07. Compensation and Indemnification of Trustee and
Its Prior Claim. The Company covenants and agrees to pay to the Trustee from
time to time, and the Trustee shall be entitled to, reasonable compensation for
all services rendered by it hereunder (which, to the extent lawful, shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust) and the Company covenants and agrees to pay or reimburse the
Trustee and each predecessor Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by or on behalf of it in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the 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
wilful misconduct. When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 5.01(g) or Section
5.01(h), the expenses (including the reasonable compensation and the expenses
and disbursements of its counsel) and the compensation for the services are
intended to constitute expenses of administration under any applicable Federal
or state bankruptcy, insolvency or other similar law. The Company also covenants
to indemnify the Trustee and each predecessor Trustee, and their respective
officers, agents and employees for, and to hold them harmless against, any
claim, loss, liability, tax, assessment or other governmental charge (other than
taxes applicable to the Trustee's compensation hereunder) or expense incurred
without negligence, bad faith or wilful 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
and also including any liability which the Trustee may incur as a result of
failure to withhold, pay or report any tax, assessment or other governmental
charge, and the costs and expenses of defending itself against or investigating
any claim of liability in the premises. The obligations of the Company under
this Section to compensate and indemnify the Trustee and each predecessor

                                                                              61

<PAGE>

Trustee and to pay or reimburse the Trustee and each predecessor Trustee for
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. As
security for the performance of the obligations of the Company under this
Section, the Trustee shall have a lien prior to the Notes upon all property and
funds held or collected by the Trustee as such, except funds held in trust for
the benefit of Holders of particular Notes.

                  SECTION 6.08. Conflicting Interests. The Trustee shall comply
with the provisions of Section 310(b) of the Trust Indenture Act. Nothing herein
shall prevent the Trustee from filing with the Commission the application
referred to in the second to last paragraph of Section 310(b) of the Trust
Indenture Act.

                  SECTION 6.09. Corporate Trustee Required; Eligibility. There
shall at all times be a Trustee hereunder which shall be eligible to act as
Trustee under the Trust Indenture Act Section 310(a)(1) and which shall have a
combined capital and surplus of at least $100,000,000, and have a Corporate
Trust Office in The City of New York to the extent there is such an institution
eligible and willing to serve. If the Trustee does not have an office in The
City of New York, the Trustee shall appoint an agent in The City of New York
reasonably acceptable to the Company to conduct any activities which the Trustee
is required under this Indenture to conduct in The City of New York. The Trustee
may not rescind any such agency without the consent of the Company, which
consent may not be unreasonably withheld, unless the Trustee appoints a
satisfactory replacement or has a Corporate Trust Office in The City of New
York. If such corporation 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, 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, the Trustee shall
resign immediately in the manner and with the effect hereinafter specified in
this Article.

                  SECTION 6.10. 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 6.11.

                  (b)      The Trustee, or any trustee or trustees hereafter
appointed, may at any time resign with respect to any Notes by giving written
notice thereof to the Company. Upon receiving such notice of resignation, the
Company shall use its best efforts to promptly appoint a successor Trustee by
Board Resolution or written instrument executed by authority of the Board of
Directors, 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 may, or any Holder
who has been a bona fide Holder of a Note for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee. Such court may
thereupon, after such notice, if any, as it may deem proper, appoint a successor
Trustee.

                                                                              62

<PAGE>

                  (c)      The Trustee may be removed with respect to any Notes
at any time by an Act of the Holders of not less than a majority in aggregate
principal amount of the Outstanding Notes, 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) with respect to any Notes after
         written request therefor by the Company or by any Holder who has been a
         bona fide Holder of a Note for at least six months, or

                  (2)      the Trustee shall cease to be eligible under Section
         6.09 with respect to any Notes and shall fail to resign after written
         request therefor by the Company or by any such Holder, or

                  (3)      the Trustee shall become incapable of acting with
         respect to any Notes 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,
with respect to any Notes or in the case of bankruptcy or insolvency or
receivership pursuant to clause (3) above, with respect to all Notes, or (ii)
subject to Section 5.14, any Holder of any Note who has been a bona fide Holder
of a Note 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 with respect to the
Notes, or in the case of bankruptcy or insolvency or receivership pursuant to
clause (3) above, with respect to all Notes. Such court may thereupon, after
such notice, if any, as it may deem proper, remove the Trustee and appoint a
successor Trustee.

                  (e)      If the Trustee shall resign, be removed or become
incapable of acting with respect to any Notes, or if a vacancy shall occur in
the office of Trustee with respect to any Notes for any cause, the Company, by a
Board Resolution or written instrument executed by authority of the Board of
Directors, shall use its best efforts to promptly appoint a successor Trustee
for such Notes and shall comply with the applicable requirements of Section
6.11. If, within one year after such resignation, removal or incapability, or
the occurrence of such vacancy, the Company or a court of competent jurisdiction
has not appointed a successor Trustee, a successor Trustee with respect to such
Notes shall be appointed by Act of the Holders of a majority in principal amount
of the Outstanding Notes delivered to the Company and the retiring Trustee, and
the successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment, become the successor Trustee with respect to such Notes and
supersede the successor Trustee appointed by the Company with respect to such
Notes. If no successor Trustee shall have been so appointed by the Company or
the Holders of such Notes and accepted appointment in the manner hereinafter
provided, any Holder of a Note who has been a bona fide Holder of a Note for at
least six months may, subject to Section 5.14, 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 such Notes.

                                                                              63

<PAGE>

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

                  SECTION 6.11. Acceptance of Appointment by Successor. In case
of the appointment hereunder of a successor Trustee with respect to the Notes,
every such successor Trustee so appointed shall execute, acknowledge and deliver
to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee under this Indenture with respect to any such
Notes; but, nevertheless, on the written request of the Company or the successor
Trustee, upon payment of its charges then unpaid, such retiring Trustee shall
pay over to the successor Trustee all moneys at the time held by it hereunder
with respect to any such Notes 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. Any Trustee
ceasing to act shall, nevertheless, retain a prior claim upon all property or
funds held or collected by such Trustee or such successor Trustee to secure any
amounts then due such Trustee pursuant to the provisions of Section 6.07.

                  No successor Trustee with respect to the Notes shall accept
appointment as provided in this Section 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 VI and shall have a
combined capital and surplus of at least $100,000,000 and have a Corporate Trust
Office or an agent selected in accordance with Section 6.09 in The City of New
York.

                  Upon acceptance of appointment by any successor Trustee as
provided in this Section, the Company shall give notice thereof to the Holders
of the Notes, by mailing such notice to such Holders at their addresses as they
shall appear on the Note Register. If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for
by the preceding sentence may be combined with the notice called for by Section
6.10. 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.

effect which this Indenture provides for the certificate of authentication of
the Trustee; provided that the right to adopt the certificate of authentication
of any predecessor Trustee or to authenticate Notes in the name of any

         necessary, such supplemental Security Agreement and supplemental
         Support Agreement) comply with the provisions described in this Section
         8.01(b), and that all conditions precedent herein provided for in this

                  SECTION 8.02. Successor Substituted. Upon any consolidation,
amalgamation or merger, or any sale, assignment, conveyance, transfer, lease or
disposition of all or substantially all of the properties and assets on a
Consolidated basis of the Company or any Note Guarantor in accordance with
Section 8.01 with respect to which the Company or any Note Guarantor is not the
continuing corporation, the successor Person formed by such consolidation or
into which the Company or such Note Guarantor is merged or the successor Person
to which such sale, assignment, conveyance, transfer, lease or disposition is
made shall succeed to, and be substituted for, and may exercise every right and
power of, the Company or such Note Guarantor, as the case may be, under this
Indenture, with the same effect as if such successor had been named as the
Company or a Note Guarantor, as the case may be, herein. When a successor
assumes all the obligations and covenants of its predecessor under this
Indenture or the Notes, the predecessor shall be released from those obligations
and covenants; provided that, in the case of a transfer by lease, the
predecessor shall not be released from the payment of principal and interest on
the Notes or, in the case of a Note Guarantor, its Guarantee.

                  Any successor to the Company described in the foregoing
paragraph may cause to be signed, and may issue either in its own name or in the
name of the Company, any or all of the Notes issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such successor, instead of the Company, and
subject to all the terms, conditions and limitations in this Indenture
prescribed, the Trustee shall authenticate and shall deliver any Notes which
previously shall have been signed and delivered by the officers of the Company
to the Trustee for authentication, and any Notes which such successor thereafter
shall cause to be signed and delivered to the Trustee for that purpose. All the
Notes so issued shall in all respects have the same legal rank and benefit under
this Indenture as the Notes theretofore or thereafter issued in accordance with
the terms of this Indenture as though all of such Notes had been issued at the
date of the execution of this Indenture.

         release Guarantees as provided by the terms of this Indenture;

                  (e)      to mortgage, pledge, hypothecate or grant a security
         interest in favor of the Trustee for the benefit of the Holders as

         Agreement or otherwise;

         Restricted Subsidiaries, as applicable, for the benefit of the Holders
         of the Notes (and if such covenants or the surrender of such right or
         power are to be for the benefit of less than all Notes, stating that
         such covenants are expressly being included or such surrenders are
         expressly being made solely for the benefit of one or more specified
         Notes), or to surrender any right or power conferred upon the Company
         or its Restricted Subsidiaries by this Indenture or the Notes;

         Senior Notes Collateral permitted under this Indenture or the Security
         Agreement;

                  (i)      to evidence and provide the acceptance of the
         appointment of a successor Trustee hereunder;

         shall not adversely affect the interests of the Holders; and

                  (k)      to establish any form of Note, as provided in Article
         Two, and to provide for the issuance of any Notes as provided in
         Article Three and to set forth the terms thereof, and/or to add to the

                                                                              71

         Intercompany Note and of the Company under the Support Agreement,
         respectively, in any manner adverse to the Holders.

                  Upon the written request of the Company, accompanied by a copy
of a Board Resolution authorizing the execution of any such supplemental
indenture, and upon the filing with the Trustee of evidence of the consent of
Holders as aforesaid, the Trustee shall join with the Company in the execution
of such supplemental indenture.

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

                  SECTION 9.03. Execution of Supplemental Indentures and
Agreements. In executing, or accepting the additional trusts created by, any
supplemental indenture, agreement or instrument permitted by this Article or the
modifications thereby of the trusts created by this Indenture, the Trustee shall
be entitled to receive, and (subject to Trust Indenture Act Section 315(a)
through 315(d) and Section 6.03 hereof) shall be fully protected in relying
upon, an Opinion of Counsel and an Officers' Certificate to the effect that the
execution of such supplemental indenture, agreement or instrument is authorized
or permitted by this Indenture. The Trustee may, but shall not be obligated to,
enter into any such supplemental indenture, agreement or instrument which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

                  SECTION 9.04. Effect of Supplemental Indentures. Upon the
execution of any supplemental indenture under this Article, this Indenture shall
be modified in accordance therewith, and such supplemental indenture shall form
a part of this Indenture for all purposes; and every Holder of Notes theretofore
or thereafter authenticated and delivered hereunder shall be bound thereby.

                  SECTION 9.05. Conformity with Trust Indenture Act. Every
supplemental indenture executed pursuant to this Article shall conform to the
requirements of the Trust Indenture Act as then in effect.

                  SECTION 9.06. Reference in Notes to Supplemental Indentures.
Notes authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article IX may, and shall if required by the Trustee,
bear a notation in form approved by the Trustee as to any matter provided for in
such supplemental indenture. If the Company shall so determine, new Notes
modified so as to conform to any such supplemental indenture, in the opinion of
the Trustee and the Board of Directors, may be prepared and executed by the
Company and authenticated and delivered by the Trustee in exchange for
outstanding Notes.

                  SECTION 9.07. Record Date. If the Company shall solicit from
the Holders of any Notes any request, demand, authorization, direction, notice,
consent, waiver or other Act, the Company may, but shall not be obligated to,
fix a record date for the purpose of determining the Holders of the Notes
entitled to consent to any supplemental indenture, agreement or instrument or
any waiver, and shall promptly notify the Trustee of any such record date. If a
record date is fixed, those Persons who were Holders of the Notes at such record
date (or their duly designated

                                                                              72

proxies), and only those Persons, shall be entitled to consent to such
supplemental indenture, agreement or instrument or waiver or to revoke any
consent previously given, whether or not such Persons continue to be Holders
after such record date. The record date shall be a date no more than 30 days
prior to the first solicitation of Holders generally in connection therewith and
no later than the date such solicitation is completed. No such consent shall be
valid or effective for more than six months after such record date. Subject to
applicable law, until any supplemental indenture, agreement, instrument or
waiver becomes effective, or a consent to it by a Holder of a Note shall cease
to be valid and effective as set forth in the preceding sentence, such consent
is a continuing consent by the Holder and every subsequent Holder of a Note or
portion of a Note that evidences the same debt as the consenting Holder's Note.

                                    ARTICLE X

                                    Covenants

                  SECTION 10.01. Payment of Principal, Premium and Interest.
With respect to each Note, the Company will duly and punctually pay the
principal of, premium, if any, and interest on such Note in accordance with the
terms of such Note and this Indenture.

                  SECTION 10.02. Maintenance of Office or Agency. The Company
will maintain in The City of New York an office or agency where Notes may be
presented or surrendered for payment, where Notes may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Company in respect of the Notes and this Indenture may be served. The office
of the Trustee at 40 Broad Street, 5th Floor, New York, NY 10004, shall be such
office or agency of the Company, unless the Company shall designate and maintain
some other office or agency for one or more of such purposes. The Company will
give prompt written notice to the Trustee of any change in the location of any
such office or agency. If at any time the Company shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

                  The Company may from time to time designate one or more other
offices or agencies (in or outside of The City of New York) where the Notes may
be presented or surrendered for any or all such purposes, and may from time to
time rescind such designation; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in The City of New York for such purposes. The Company will
give prompt written notice to the Trustee of any such designation or rescission
and any change in the location of any such office or agency.

                  SECTION 10.03. Money for Note Payments to be Held in Trust.
The Company will, on or before Noon, New York time, on each due date of the
principal of, premium, if any, or interest on, the Notes, deposit with a Paying
Agent (which shall not be the Company) a sum in same-day funds sufficient to pay
the principal, premium, if any, or interest so becoming due, such sum to be held
in trust for the benefit of the Persons entitled to such principal, premium or

                                                                              73

<PAGE>

interest, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of such action or any failure so to act.

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

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

                  (b)      give the Trustee notice of any Default by the Company
         (or any other obligor upon the Notes) in the making of any payment of
         principal, premium, if any, or interest on the Notes;

                  (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 with respect to the Notes or for
any other purpose, by the Company Order direct any Paying Agent to pay to the
Trustee all sums held in trust by such Paying Agent in respect of the Notes as
to which it seeks to discharge this Indenture or, if for any other purpose, all
sums so held in trust by the Company in respect of all Notes, such sums to be
held by the Trustee upon the same trusts as those upon which such sums were held
by such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

                  Any money deposited with the Trustee or any Paying Agent in
trust for the payment of the principal of, premium, if any, or interest on any
Note 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 upon Company Request; and the Holder of such Note 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 payment to the Company, may at the expense of the
Company cause to be published once, in The New York Times and The Wall Street
Journal (national edition), 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 or publication, any unclaimed balance of such money
then remaining will promptly be repaid to the Company.

                  SECTION 10.04. Corporate Existence. Subject to Article VIII,
the Company will do or cause to be done all things necessary to preserve and
keep in full force and effect its

                                                                              74

<PAGE>

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 if the Board of Directors shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company and its Restricted Subsidiaries as a whole and that
the loss thereof would not reasonably be expected to have a material adverse
effect on the ability of the Company to perform its obligations hereunder; and
provided further, however, that the foregoing shall not prohibit a sale,
transfer or conveyance of a Restricted Subsidiary or any of its assets in
compliance with the terms of this Indenture.

                  SECTION 10.05. Payment of Taxes and Other Claims. The Company
will pay or discharge or cause to be paid or discharged, on or before the date
the same shall become due and payable, (a) all material taxes, assessments and
governmental charges levied or imposed upon the Company or any Restricted
Subsidiary shown to be due on any tax return of the Company or any Restricted
Subsidiary or otherwise assessed or upon the income, profits or property of the
Company or any Restricted Subsidiary and (b) all material lawful claims for
labor, materials and supplies, which, if unpaid, would by law become a Lien upon
the property of the Company or any Restricted Subsidiary, except for any Lien
permitted to be Incurred under Section 10.11; provided, however, that the
Company shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings properly
instituted and diligently conducted and in respect of which appropriate reserves
(in the good-faith judgment of management of the Company) are being maintained
in accordance with GAAP consistently applied.

                  SECTION 10.06. Maintenance of Properties. The Company will
cause all material properties owned by the Company or any Restricted Subsidiary
or used or held for use in the conduct of its business or the business of any
Restricted Subsidiary to be maintained and kept in good condition, repair and
working order (ordinary wear and tear excepted) and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be consistent with sound business practice and reasonably
necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that
nothing in this Section shall prevent the Company from discontinuing the
maintenance of any of such properties if such discontinuance is, in the judgment
of the Company, desirable in the conduct of the business of the Company and its
Restricted Subsidiaries and not reasonably expected to have a material adverse
effect on the ability of the Company to perform its obligations hereunder.

                  SECTION 10.07. Insurance. The Company will at all times keep
all of its and its Restricted Subsidiaries' properties which are of an insurable
nature reasonably self-insured or insured with insurers, believed by the Company
to be responsible, against loss or damage to the extent that property of similar
character is usually so insured by corporations similarly situated and owning
like properties in the same general geographic areas in which the Company and
its Restricted Subsidiaries operate, except where the failure to do so would not
reasonably be expected to have a material adverse effect on the condition
(financial or otherwise), earnings, business affairs or prospects of the Company
and its Restricted Subsidiaries, taken as a whole.

                                                                              75

<PAGE>

                  SECTION 10.08. Limitation on Indebtedness. The Company will
not, and will not permit any of its Restricted Subsidiaries to, Incur any
Indebtedness, including any Acquired Indebtedness, but excluding any Permitted
Indebtedness.

                  SECTION 10.09. Limitation on Restricted Payments. (a) The
Company will not, and will not permit any Restricted Subsidiary to, directly or
indirectly:

                  (i)      declare or pay any dividend or make any other
         distribution or payment on or in respect of the Company's Capital Stock
         (including dividends or distributions of the Capital Stock of any
         Subsidiary), or make any other payment to the direct or indirect
         holders (in their capacities as such) of the Company's Capital Stock
         (other than (x) the Permitted Distribution and (y) dividends or
         distributions payable in shares of the Company's Qualified Capital
         Stock or in options, warrants or other rights to acquire such Qualified
         Capital Stock);

                  (ii)     purchase, redeem or otherwise acquire or retire for
         value, directly or indirectly, any Capital Stock of the Company or any
         Capital Stock of any Affiliate of the Company (other than Capital Stock
         of any Restricted Subsidiary or Capital Stock of a Person that is, or
         immediately following such repurchase will become, a Restricted
         Subsidiary), or options, warrants or other rights to acquire such
         Capital Stock;

                  (iii)    make any principal payment on, or repurchase, redeem,
         defease, retire or otherwise acquire for value, prior to any scheduled
         principal payment, sinking fund payment or maturity, any Subordinated
         Indebtedness (other than Subordinated Indebtedness owing by the Company
         to any Restricted Subsidiary, by any Restricted Subsidiary to the
         Company or by any Restricted Subsidiary to any other Restricted
         Subsidiary) or make any cash interest payment on the International
         Intercompany Note;

                  (iv)     declare or pay any dividend or distribution on any
         Capital Stock of any Restricted Subsidiary to any Person (other than
         (x) dividends and distributions on Preferred Stock of Restricted
         Subsidiaries or (y) dividends and distributions made to any Person on a
         pro rata basis consistent with the ownership interests in such Capital
         Stock to the owners of such Capital Stock, except that, in the case of
         the Capital Stock of a Restricted Subsidiary that has provided a
         Guarantee, (i) no Default or Event of Default shall have occurred and
         be continuing; and (ii) no holders of any other Indebtedness of the
         Company or any Restricted Subsidiary shall have an Acceleration Right);

                  (v)      Incur, create or assume any guarantee of Indebtedness
         of any Affiliate of the Company (other than a Restricted Subsidiary of
         the Company);

                  (vi)     make any Restricted Investment in any Person; or

                  (vii)    designate any Restricted Subsidiary as an
         Unrestricted Subsidiary;

any such action that is a Permitted Payment (as defined below), collectively,

proposed Restricted Payment (the amount of any such Restricted Payment, if other
than cash, as determined by the Board of Directors, whose

                                                                              76

Default or Event of Default shall have occurred and be continuing; (2) no
holders of any other Indebtedness of the Company or any Restricted Subsidiary
shall have an Acceleration Right; and (3) the aggregate amount expended by the
Company and its Restricted Subsidiary (provided that, in the case of a
Restricted Payment by a Restricted Subsidiary, such Restricted Payment is
calculated for the purposes of this paragraph (3) by multiplying the amount of
the Restricted Payment by the percentage of the Company's common equity interest
in such Restricted Subsidiary at the time of such Restricted Payment) in
connection with all Restricted Payments made subsequent to the Issue Date, taken
together with any payments made pursuant to paragraph (b)(viii) below, shall not
exceed the sum of (without duplication):

                  (A)      50% of the aggregate cumulative Adjusted Net Cash
         Flow of the Company and its Restricted Subsidiaries accrued during the
         period (treated as a single accounting period) beginning on the first
         day of the Company's fiscal quarter commencing prior to the date of
         this Indenture and ending on the last day of the Company's last fiscal
         quarter ending prior to the date of the Restricted Payment; plus

                  (B)      the aggregate Net Cash Proceeds received after the
         date of this Indenture by the Company from the issuance or sale (other
         than to any of its Restricted Subsidiaries) of its Qualified Capital
         Stock or any options, warrants or rights to purchase such Qualified
         Capital Stock (except, in each case, to the extent such proceeds are
         used to purchase, redeem or otherwise retire Capital Stock or
         Subordinated Indebtedness of the Company as set forth in (b)(iv) and
         (b)(v) below); plus

                  (C)      the aggregate Net Cash Proceeds received after the

         to purchase Qualified Capital Stock of the Company subsequent to the
         Issue Date (except to the extent such proceeds are used to purchase,
         redeem or otherwise retire Capital Stock or Subordinated Indebtedness
         of the Company as set forth in (b)(iv) and (b)(v) below); plus

                  (D)      the aggregate amount by which any Permitted
         Indebtedness of the Company or any Restricted Subsidiary is reduced
         after the date of this Indenture as a result of the conversion or
         exchange of debt securities or Redeemable Capital Stock of the Company
         that has been converted into or exchanged for Qualified Capital Stock
         of the Company to the extent such debt securities or Redeemable Capital
         Stock plus the aggregate Net Cash Proceeds received by the Company at
         the time of any such conversion or exchange were originally sold for
         cash; plus

                  (E)      the aggregate Net Cash Proceeds received after the
         Issue Date by the Company from cash capital contributions made to the
         Company (other than from a Restricted Subsidiary, and other than cash
         capital contributions made pursuant to the Support Agreement); plus

                  (F)      the aggregate Net Cash Proceeds of any (x) sale or

         liquidating or otherwise, from, or the sale of capital stock of, an
         Unrestricted Subsidiary, or (z) dividends or other distributions,
         whether liquidating or otherwise, from Restricted Investments (which
         Investment was made after the Issue Date); plus

                  (G)      with respect to any Unrestricted Subsidiary that is
         redesignated by the Board of Directors as a Restricted Subsidiary, an
         amount equal to the lower of (x) the fair market value (as determined
         by a majority of the Independent Directors of the Board of Directors
         and evidenced by a Board Resolution) of the Company's or a Restricted
         Subsidiary's interest in such Unrestricted Subsidiary or (y) the amount
         of the original Investment by the Company or such Restricted Subsidiary
         in such Unrestricted Subsidiary plus any additional Investment made in
         such Unrestricted Subsidiary after the date such Subsidiary was so
         designated; provided that in determining the amount of the Investment
         by the Company or such Restricted Subsidiary in (1) any Subsidiary
         designated as an Unrestricted Subsidiary as of the date of this
         Indenture, such amount shall be the fair market value of such
         Unrestricted Subsidiary as at the date of this Indenture, (2) any
         Restricted Subsidiary that is designated as an Unrestricted Subsidiary
         after the date of this Indenture, such amount shall be the fair market
         value of such Unrestricted Subsidiary as at the date of such
         designation, and (3) any Investment made in an Unrestricted Subsidiary
         after the date such Subsidiary was so designated, such amount shall be
         equal to the cash amount so invested or the fair market value of any
         property contributed; plus

                  (H)      Cdn. $30,000,000.

The sum of the amounts provided for in clauses (3)(A) through (3)(H) above, less
the aggregate amount of Restricted Payments made by the Company and its
Restricted Subsidiaries, is referred to in this Indenture as the "RP Available
Amount."

                  (b)      Notwithstanding the foregoing (and, in the case of
clauses (ii) through (viii) below, so long as (1) no Default or Event of Default
shall have occurred and be continuing or shall occur as a consequence of the
actions or payments set forth therein and (2) no holders of any other
Indebtedness of the Company or any Restricted Subsidiary have an Acceleration
Right), the foregoing provisions will not prohibit the following actions
(clauses (i) through (viii) of this subsection (b) being referred to as
"Permitted Payments"):

                  (i)      the payment of any dividend or distribution within 60
         days after the date of declaration thereof, if at such date of
         declaration such payment would be permitted by the provisions of
         paragraph (a) of this Section and such payment will be deemed to have
         been paid on such date of declaration for purposes of the calculation
         required by paragraph (a) of this Section;

                  (ii)     the payment of any dividend or distribution on (1)
         the Series II Preferred Shares (and any Capital Stock issued in
         connection with the purchase, redemption, retirement or other
         refinancing of the Series II Preferred Shares permitted under this
         Indenture), in an amount not to exceed the aggregate dividends paid by
         Hollinger International to the Company on Class A Common Stock that
         corresponds to the number of shares of Class A Common Stock into which
         the Series II Preferred Shares are

                                                                              78

         exchangeable and (2) the Series III Preferred Shares (and any Capital
         Stock issued in connection with the purchase, redemption, retirement or
         other refinancing of the Series III Preferred Shares permitted under
         this Indenture), in an amount not to exceed Cdn. $9 million in any
         calendar year;

                  (iii)    the payment of any dividend or distribution on the

         Stock of the Company, or (3) a combination of clauses (1) and (2)
         above; provided, in each case, that such new Subordinated
         Indebtedness or Redeemable Capital Stock or combination thereof shall
         be in an aggregate principal amount or redemption amount, as the case
         may be, that does not exceed the redemption amount of the Series III

         holder of such shares of the retraction right attached to such shares.

                  (c)      For purposes of this Section, if the Board of
Directors designates a Restricted Subsidiary as an Unrestricted Subsidiary, a
"Restricted Payment" shall be deemed to have been made in an amount equal to the
fair value of the Investment of the Company and its other Restricted
Subsidiaries in such Unrestricted Subsidiary as determined by the Board of
Directors with the concurrence of a majority of the Independent Directors (there
being at least one Independent Director), whose good faith determination shall
be conclusive. If a particular Restricted Payment involves a non-cash payment,
including a distribution of assets, then such Restricted Payment shall be deemed
to be in an amount equal to the fair market value of the non-cash portion of
such Restricted Payment as determined by the Board of Directors, whose good
faith determination shall be conclusive.

                  SECTION 10.10. Limitation on Transactions with Affiliates. The
Company will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, enter into or suffer to exist any transaction or series
of related transactions (including, without limitation, the sale, purchase,
exchange or lease of assets, property or services) with any Affiliate of the
Company (other than the Company or a Restricted Subsidiary) unless (a) such
transaction or series of related transactions is on terms that are no less
favorable to the Company or such Restricted Subsidiary, as the case may be, than
would be available in a comparable transaction in arm's-length dealings with an
unrelated third party and (b) with respect to any transaction or series of
related transactions involving aggregate payments in excess of $1,000,000, the
Company delivers an Officers' Certificate to the Trustee certifying that such
transaction or series of related transactions complies with clause (a) above and
such transaction or series of related transactions has been approved by a
majority of the Independent Directors of the Board of Directors (or, if the
Company ceases to be a public company, by a majority of the members of the Board
of Directors); provided that any transaction or series of related transactions
otherwise permitted under this paragraph (other than any transaction or series
of related transactions with respect to the making of any Restricted Payment
permitted pursuant to Section 10.09) pursuant to which the Company or any
Restricted Subsidiary shall receive or render value exceeding $5,000,000 shall
not be permitted unless, prior to the consummation of any such transaction or
series of related transactions, the Company shall have received an opinion, from
an independent nationally recognized investment banking firm or firm experienced
in the appraisal or similar

                                                                              80

Company from a financial point of view; provided further that this covenant
shall not apply to:

                  (i)      transactions or agreements as in effect or securities
         outstanding on the date of this Indenture (provided that any amendment
         to any existing agreement, and any transaction pursuant to the Business
         Opportunities Agreement, shall require approval pursuant to this
         covenant; notwithstanding the foregoing, any amendment to the Services
         Agreement or the Business Opportunities Agreement shall only require
         the approval of a majority of the Independent Directors of the Board of
         Directors);

                  (ii)     directors' fees approved by the Board of Directors;

         or made available to officers or other employees of the Company or the
         Restricted Subsidiaries in the ordinary course of business;

                  (iv)     the performance by RMI, RCL, the Company and any
         Restricted Subsidiary of their respective obligations under the Support
         Agreement (and the related Contribution Agreement), the Security
         Documents and this Indenture or the contribution by RMI or RCL of any
         voluntary support amounts to the Company;

                  (v)      for so long as the Company is a public company, any
         sale to Hollinger International of shares of Capital Stock of Hollinger
         International held by the Company or its Restricted Subsidiaries for
         fair value (as determined by a majority of the Independent Directors of
         the Board of Directors); and

                  (vi)     a purchase by RMI or its Affiliates from the Company
         or any of its Restricted Subsidiaries and substantially concurrent sale
         in an arm's-length transaction by RMI or its Affiliates to a third
         party (other than an Affiliate of the Company or RMI) or to Hollinger
         International of shares of Capital Stock of Hollinger International
         where the purchase and sale were undertaken at the same price and RMI
         delivers an Officers' Certificate to the Trustee certifying that such
         purchase and sale of such shares were undertaken at the same price.

                  SECTION 10.11. Limitation on Liens. (a) The Company will not,
and will not permit any Restricted Subsidiary to, create, incur, assume or
suffer to exist any Lien on any of its assets or properties of any character, or
any shares of Capital Stock or Indebtedness of any Restricted Subsidiary,
without making effective provision for all of the Notes and all other amounts
due under this Indenture to be directly secured equally and ratably with (or, if
the obligation or liability to be secured by such Lien is subordinated in right
of payment to the Notes, prior to) the obligation or liability secured by such
Lien.

                  (b)      The foregoing limitation does not apply to:

                  (i)      Liens (other than on the Capital Stock of NBI (until
         and unless the NBI Guarantee shall have been released in accordance
         with this Indenture) or any of the Senior Notes Collateral) securing
         Indebtedness incurred under the Credit Facility that is permitted to be
         incurred under the definition of "Permitted Indebtedness";

                                                                              81

                  (ii)     Liens existing on the Issue Date;

                  (iii)    Liens granted after the Issue Date on any assets or
         Capital Stock of the Company or its Restricted Subsidiaries created in
         favor of the Holders;

                  (iv)     Liens with respect to the assets of a Restricted
         Subsidiary granted by such Restricted Subsidiary to the Company or a
         Restricted Subsidiary to secure Indebtedness owing to the Company or
         such other Restricted Subsidiary;

                  (v)      Liens securing Indebtedness which is Incurred to
         refinance secured Indebtedness which is permitted to be Incurred under
         clause (viii) of the definition of "Permitted Indebtedness"; provided
         that such Liens do not extend to or cover any property or assets of the
         Company or any Restricted Subsidiary other than the property or assets
         securing the Indebtedness being refinanced;

                  (vi)     Liens on any property or assets or capital stock of a
         Restricted Subsidiary securing Indebtedness of such Restricted
         Subsidiary permitted under the definition of "Permitted Indebtedness";
         or

                  (vii)    Permitted Liens.

                  SECTION 10.12. Limitation on Issuances of Guarantees of
Indebtedness. (a) The Company will not permit any Restricted Subsidiary (other
than NBI), directly or indirectly, to guarantee, assume or in any other manner
become liable with respect to any Indebtedness of the Company (other than
pursuant to a Credit Facility) unless such Restricted Subsidiary simultaneously
executes and delivers a supplemental indenture to this Indenture providing for a
senior Guarantee of the Notes and if such Indebtedness of the Company is by its
terms pari passu with or expressly subordinated to the Notes, any such
assumption, guarantee or other liability of such Restricted Subsidiary with
respect to such Indebtedness shall be pari passu with or subordinated to such
Restricted Subsidiary's Guarantee to the same extent as such Indebtedness is
pari passu with or subordinated to the Notes.

                  (b)      Notwithstanding the foregoing, any Guarantee by a
Restricted Subsidiary of the Notes that is provided pursuant to the foregoing
paragraph may provide by its terms that it shall be automatically and
unconditionally released and discharged (i) upon any sale, exchange or transfer,
to any Person not an Affiliate of the Company, of all of the Company's Capital
Stock in, or all or substantially all the assets of, such Restricted Subsidiary,
which sale, exchange or transfer is in compliance with this Indenture, (ii) if
the Restricted Subsidiary issuing such Guarantee ceases to be a Restricted
Subsidiary or (iii) upon the release by the holders of the Indebtedness of the
Company described in paragraph (a) above of their guarantee by such Restricted
Subsidiary (including any deemed release upon payment in full of all obligations
under such Indebtedness), at a time when (A) no other Indebtedness of the
Company or any Restricted Subsidiary has been guaranteed by such Restricted
Subsidiary or (B) the holders of all such other Indebtedness which is guaranteed
by such Restricted Subsidiary also release their guarantee by such Restricted
Subsidiary (including any deemed release upon payment in full of all obligations
under such Indebtedness).

                                                                              82

                  SECTION 10.13. Limitation on Sale of Assets. (a) The Company
will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, consummate an Asset Sale unless:

                  (i)      at least 75% of the proceeds from such Asset Sale are
         received in cash (provided that the amount of (A) any Pari Passu
         Indebtedness of the Company or Indebtedness of any such Restricted
         Subsidiary that is pari passu with any guarantee of the Notes (as shown
         on the Company's or such Restricted Subsidiary's most recent balance
         sheet or in the notes thereto) of the Company or any such Restricted
         Subsidiary that is assumed by the transferee of any asset in connection
         with any Asset Sale and (B) any deferred payment obligations received
         by the Company or any such Restricted Subsidiary as proceeds of an
         Asset Sale that are concurrently with the Asset Sale converted into
         cash without recourse to the Company or any of its Restricted
         Subsidiaries shall be deemed to be cash for purposes of this provision;
         provided further that for purposes of this clause (i), "cash" shall
         include any cash proceeds received from the sale of securities received
         in an Asset Sale as long as, at the time of such Asset Sale, the
         Company or its Restricted Subsidiary, as applicable, has entered into a
         legally binding agreement for the sale of such securities and such
         securities are sold within 90 days of such Asset Sale; and provided
         further that this clause (i) shall not apply to

                           (x)      any contribution, sale or other disposition
                  of shares of Capital Stock of Hollinger International held by
                  the Company or its Restricted Subsidiaries (other than the
                  Pledged Share Collateral) to Hollinger International or its
                  Subsidiaries in satisfaction of such portion of any
                  Indebtedness owed by the Company or any of its Restricted
                  Subsidiaries to Hollinger International or its Subsidiaries
                  under the International Intercompany Note as is no less than
                  90% of the aggregate Current Market Price of the shares of
                  Capital Stock of Hollinger International so contributed, sold
                  or disposed of, so long as and to the extent that the
                  repayment of such Indebtedness would be permitted under the
                  provisions of Section 10.09 and Section 10.10, or

                           (y)      any sale of an interest in the Company's
                  newspaper businesses in the Cayman Islands held through Holcay
                  Holdings Ltd., or in Costa Rica held through 172847 Canada
                  Limited, to Hollinger International or its Subsidiaries in
                  satisfaction of such portion of any Indebtedness owed by the
                  Company or any of its Restricted Subsidiaries to Hollinger
                  International or its Subsidiaries under the International
                  Intercompany Note as is equal to the fair market value of the
                  shares or assets so sold, so long as and to the extent that
                  the repayment of such Indebtedness would be permitted under
                  the provisions of Section 10.09 and Section 10.10; and

                  (ii)     The Company or such Restricted Subsidiary receives
         consideration at the time of such Asset Sale at least equal to the fair
         market value of the shares or assets sold (as determined by the Board
         of Directors of the Company and evidenced by a Board Resolution). The
         value of any properties or assets (other than cash) received pursuant
         to an Asset Sale shall be determined by the Board of Directors of the
         Company and evidenced by a Board Resolution; provided, that if the
         value of the asset which is the

                                                                              83

<PAGE>

         subject of the Asset Sale is in excess of $5,000,000, the value of the
         properties or assets received shall be determined by an independent
         nationally recognized investment banking firm or firm experienced in
         the appraisal or similar review of similar types of assets.

                  (b)      The Company will, and will cause its Restricted
Subsidiaries to, apply 100% of the Net Cash Proceeds of any Asset Sale:

                  (i)      first, (A) to the extent the Company elects, to the
         reinvestment by the Company or such Restricted Subsidiary in properties
         and assets that (as determined by the Board of Directors) replace the
         properties and assets that were the subject of the Asset Sale or in
         properties and assets that will be used in the businesses of the
         Company or its Restricted Subsidiaries existing on the date of this
         Indenture or in businesses reasonably related thereto or (B) to the
         extent the Company elects to the making of an offer to purchase (an
         "Offer"), out of such amount of the Net Cash Proceeds as the Company
         shall determine to allocate for such purpose (the "Allocated
         Proceeds"), a principal amount of Notes equal to the Notes Amount (as
         defined in clause (c) below) and (to the extent so required by the
         terms of the debt instrument governing such Indebtedness) a principal
         amount of Pari Passu Indebtedness equal to the Pari Passu Amount (as
         defined in clause (c) below), any such Offer pursuant to this clause
         (b)(i)(B) to be conducted in accordance with the procedures set forth
         in clause (c) below (substituting the term "Allocated Proceeds" in
         place of any reference therein with "Excess Proceeds") and in this
         Indenture (with any Deficiency (as defined in clause (c) below)
         occurring after such Offer to be excluded from the calculation of
         Excess Proceeds and treated the same as a Deficiency occurring after an
         Offer made using Excess Proceeds), any such application pursuant to
         clauses (A) and (B) to be made within 12 months of receipt of such Net
         Cash Proceeds;

                  (ii)     second, to the extent of the balance of such Net Cash
         Proceeds after application in accordance with clause (i) above, to make
         an Offer to purchase Notes pursuant to and subject to the conditions
         set forth below; provided, however, that if the Company elects (or is
         required by the terms of any Pari Passu Indebtedness), such Offer may
         be made ratably to purchase the Notes and any Pari Passu Indebtedness
         of the Company (any Net Cash Proceeds from Asset Sales (excluding any
         Deficiency resulting from an Offer made using Allocated Proceeds
         pursuant to clause (b)(i)(B)) that are not applied as provided in
         clause (i) above shall constitute "Excess Proceeds"); and

                  (iii)    third, to the extent of the balance of any Excess
         Proceeds after application in accordance with clauses (i) and (ii)
         above, for any general corporate purpose permitted pursuant to the
         terms of this Indenture;

provided, however, that in connection with any prepayment, repayment or purchase
of Indebtedness pursuant to clauses (i)(B) and (ii) above, the Company or such
Restricted Subsidiary will retire such Indebtedness and (in the case of the
Credit Facility, to the extent of any borrowings thereunder that have been
converted to a term loan as permitted under this Indenture) will cause the
related loan commitment (if any) to be permanently reduced in an amount equal to
the principal amount so prepaid, repaid or purchased.

                                                                              84

<PAGE>

                  (c)      When the aggregate amount of Excess Proceeds equals
or exceeds $5,000,000, the Company shall apply the Excess Proceeds to the
repayment of the Notes and any Pari Passu Indebtedness required to be
repurchased under the instrument governing such Pari Passu Indebtedness as
follows: (i) the Company shall make an offer to purchase (an "Offer") from all
Holders, in accordance with the procedures set forth in this Indenture, in the
maximum principal amount (expressed as a multiple of $1,000) of Notes that may
be purchased out of an amount (the "Note Amount") equal to the product of such
Excess Proceeds multiplied by a fraction, the numerator of which is the
outstanding principal amount of the Notes, and the denominator of which is the
sum of the outstanding principal amount of the Notes and such Pari Passu
Indebtedness (subject to proration in the event such amount is less than the
aggregate Offered Price (as defined herein) of all Notes tendered) and (ii) to
the extent required by such Pari Passu Indebtedness to permanently reduce the
principal amount of such Pari Passu Indebtedness, the Company shall make an
offer to purchase or otherwise repurchase or redeem Pari Passu Indebtedness (a
"Pari Passu Offer") in an amount (the "Pari Passu Debt Amount") equal to the
excess of the Excess Proceeds over the Note Amount; provided that in no event
shall the Pari Passu Debt Amount exceed the principal amount of such Pari Passu
Indebtedness plus the amount of any premium required to be paid to repurchase
such Pari Passu Indebtedness. The offer price shall be payable in cash in an
amount equal to 100% of the principal amount of the Notes plus accrued and
unpaid interest, if any, to the date (the "Purchase Date") such Offer is
consummated (the "Offered Price"), in accordance with the procedures set forth
below. To the extent that the aggregate Offered Price of the Notes tendered
pursuant to the Offer is less than the Note Amount relating thereto or the
aggregate amount of Pari Passu Indebtedness that is purchased is less than the
Pari Passu Debt Amount (the amount of such shortfall, if any, constituting a
"Deficiency"), the Company may use such Deficiency for any purpose not otherwise
prohibited by this Indenture. Upon completion of the purchase of all Notes
tendered pursuant to an Offer and repurchase of the Pari Passu Indebtedness
pursuant to a Pari Passu Offer, the amount of Excess Proceeds, if any, shall be
reset at zero.

                  (d)      Whenever the aggregate amount of Excess Proceeds
received by the Company exceeds $5,000,000, such Excess Proceeds shall, prior to
the purchase of Notes or any Pari Passu Indebtedness described in paragraph (c)
above, be set aside by the Company in a separate account pending (i) deposit
with the depository or a Paying Agent of the amount required to purchase the
Notes or Pari Passu Indebtedness tendered in an Offer or a Pari Passu Offer and
(ii) delivery by the Company of the Offered Price to the Holders or holders of
Pari Passu Indebtedness tendered in an Offer or a Pari Passu Offer. Such Excess
Proceeds may be invested in Temporary Cash Investments; provided that the
maturity date of any such investment made after the amount of Excess Proceeds
equals or exceeds $5,000,000 shall not be later than the Purchase Date. The
Company shall be entitled to any interest or dividends accrued, earned or paid
on such Temporary Cash Investments; provided that the Company shall not be
entitled to such interest and shall not withdraw such interest from the separate
account, if an Event of Default has occurred and is continuing.

                  (e)      If the Company becomes obligated to make an Offer
pursuant to paragraph (c) above, the Notes shall be purchased by the Company, at
the option of the Holders thereof, in whole or in part in integral multiples of
$1,000, on a date that is not earlier than 30 days and not later than 60 days
from the date the notice is given to Holders, or such later date as may be
necessary for the Company to comply with the requirements under the Exchange
Act,

                                                                              85

subject to proration in the event the Note Amount is less than the aggregate
Offered Price of all Notes tendered.

                  (f)      Notwithstanding any other provision hereof, with
respect to the proceeds of an Asset Sale arising from the issuance of Capital
Stock of a Restricted Subsidiary ("Issuance Proceeds"):

                  (i)      Prior to the day following the fifth anniversary of
         the original issuance of the Notes, the Company shall not be required
         to use Issuance Proceeds to make an Offer to purchase Notes in an
         amount in excess of 25% of the original aggregate principal amount of
         the Notes. For greater certainty, the maximum amount of the Issuance
         Proceeds that may be applied to make an Offer to purchase Notes that
         has a date of purchase prior to the day following the fifth anniversary
         of the original issuance of the Notes is 25% of the original aggregate
         principal amount of the Notes less the aggregate principal amount of
         Notes previously purchased pursuant to a purchase offer using Issuance
         Proceeds. To the extent the aggregate amount of Notes tendered exceeds
         the permitted amount of the Offer, the tendered Notes shall be selected
         for repurchase on a pro-rata basis.

                  (ii)     Promptly after the fifth anniversary of the original
         issuance of the Notes, the Company shall be required to make an Offer
         to purchase Notes in accordance with the requirements set out in
         paragraph (c) above, in an aggregate amount equal to the aggregate
         amount of Issuance Proceeds in excess of 25% of the principal amount of
         the Notes that was not applied to purchase Offers pursuant to the
         provisions of this paragraph.

                  (g)      The Company shall comply with the applicable tender
offer rules, including Rule 14e-1 under the Exchange Act, and any other
applicable securities laws or regulations in connection with an Offer.

                  (h)      The Company shall not, and shall not permit any
Restricted Subsidiary to, create or permit to exist or become effective any
restriction that would expressly impair the ability of the Company to make an
Offer to purchase the Notes or, if such Offer is made, to pay for the Notes
tendered for purchase.

                  (i)      Notwithstanding anything to the contrary herein,
until and unless the NBI Guarantee shall have been released in accordance with
this Indenture, the Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, consummate an Asset Sale in respect of
any of the Capital Stock or assets and properties of either Sugra or NBI to the
extent that any such Asset Sale would impair the Lien in favor of the Collateral
Agent in the Pledged Share Collateral.

                  (j)      Within 30 days after the date on which the amount of
Excess Proceeds equals or exceeds $5,000,000, the Company shall send by
first-class mail, postage prepaid, to the Trustee and to each Holder of the
Notes, at such Holder's address appearing in the Note Register, a notice stating
or including:

                                                                              86

                  (i)      that the Holder of such Notes has the right to
         require the Company to repurchase, subject to proration, part or all of

         the Company furnished subsequent to such annual report, other than
         reports describing Asset Sales otherwise described in the offering

         comparable information required pursuant to Section 10.17), (B) a
         description of material developments in the Company's business
         subsequent to the date of the latest of such reports, (C) if material,

         information, if any, concerning the business of the Company and its

         enable such Holders to make an informed investment decision regarding
         the Offer;

                  (v)      the Offered Price;

                  (vi)     the names and addresses of the Paying Agent and the
         offices or agencies referred to in Section 10.02;

                  (vii)    that Notes must be surrendered at least three
         Business Days prior to the Purchase Date to the Paying Agent or to an
         office or agency referred to in Section 10.02 to collect payment;

                  (viii)   that any Notes not tendered will continue to accrue
         interest and that unless the Company defaults in the payment of the
         purchase price, any Note accepted for payment pursuant to the offer
         shall cease to accrue interest on and after the Purchase Date; and

                  (ix)     the procedures for withdrawing a tender.

                  (k)      Holders electing to have the Notes purchased
hereunder will be required to surrender such Notes at the address specified in
the notice at least three Business Days prior to the Purchase Date. Holders will
be entitled to withdraw their election to have their Notes purchased pursuant to
this Section if the Company receives, not later than three Business Days prior
to the Purchase Date, a telegram, telex, facsimile transmission or letter
setting forth (1) the name of the Holder, (2) the certificate number of the Note
in respect of which such notice of withdrawal is being submitted, (3) the
principal amount of the Note (which shall be $1,000 or an integral multiple
thereof) delivered for purchase by the Holder as to which his election is to be
withdrawn, (4) a statement that such Holder is withdrawing such Holder's
election to have such principal amount of such Note purchased, and (5) the
principal amount, if any, of such Note (which shall be $1,000 or an integral
multiple thereof) that remains subject to the original notice of the Offer and
that has been or will be delivered for purchase by the Company.

                                                                              87

                  (l)      the Company shall (i) not later than the Purchase
Date, accept for payment Notes or portions thereof tendered pursuant to the
Offer, (ii) not later than 11:00 a.m. (New York time) on the Purchase Date,
deposit with the Trustee or with a Paying Agent an amount of money in same day
funds (or New York Clearing House funds if such deposit is made prior to the
Purchase Date) sufficient to pay the aggregate Offered Price of all the Notes or
portions thereof which are to be purchased on that date and (iii) not later than
11:00 a.m. (New York time) on the Purchase Date, deliver to the Paying Agent an
Officers' Certificate stating the Notes or portions thereof have been accepted
for payment by the Company.

                  The Trustee and the Paying Agent shall return to the Company
any cash that remains unclaimed, together with interest, if any, thereon, held
by them for the payment of the Offered Price; provided, however, that (x) to the
extent that the aggregate amount of cash deposited by the Company with the
Trustee or a Paying Agent in respect of an Offer exceeds the aggregate Offered
Price of the Notes or portions thereof to be purchased, then the Trustee or a
Paying Agent shall hold such excess for the Company and (y) unless otherwise
directed by the Company in writing, promptly after the Business Day following
the Purchase Date the Trustee or a Paying Agent shall return any such excess to
the Company together with interest or dividends, if any, thereon.

                  (m)      Notes to be purchased shall, on the Purchase Date,
become due and payable at the Offered Price and from and after such date (unless
the Company shall default in the payment of the Offered Price) such Notes shall
cease to bear interest. The Offered Price shall be paid to such Holder promptly
following the later of the Purchase Date and the time of delivery of such Note
to the relevant Paying Agent at the office of such Paying Agent by the Holder
thereof in the manner required. Upon surrender of any such Note for purchase in
accordance with the foregoing provisions, such Note shall be paid by the Company
at the Offered Price; provided, however, that installments of interest whose
Stated Maturity is on or prior to the Purchase Date shall be payable to the
Holders of such Notes, or one or more Predecessor Notes, registered as such on
the relevant Regular Record Dates according to the terms and the provisions of
Section 3.08; provided further that Notes to be purchased are subject to
proration in the event the Excess Proceeds are less than the aggregate Offered
Price of all Notes tendered for purchase, with such adjustments as may be deemed
appropriate by the Trustee so that only Notes in denominations of $1,000 or

such Note. Any Note that is to be purchased only in part shall be surrendered to
a Paying Agent in accordance with the terms of this Section at the office of
such Paying Agent (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or such Holder's
attorney duly authorized in writing), and the Company shall execute and pursuant
to a Company Order the Trustee shall authenticate and deliver to the Holder of
such Note, without service charge, one or more new Notes of any authorized
denomination as requested by such Holder in an aggregate principal amount equal
to, and in exchange for, the portion of the principal amount of the Note so
surrendered that is not purchased.

                                                                              88

         Business Days prior to the Change of Control Purchase Date to the
         Paying Agent at the Office of the Paying Agent or to an office or
         agency referred to in Section 10.02 to collect payment;

                  I.       that the Change of Control Purchase Price for any

         Change of Control Purchase Notice;

         interest; and

                  L.       that, unless the Company defaults in the payment of
         the Change of Control Purchase Price, any Note accepted for payment

                  (c)      Upon receipt by the Company of the proper tender of
Notes, each Holder of a Note in respect of which such proper tender was made
shall (unless the tender of such Note is properly withdrawn) thereafter be
entitled to receive solely the Change of Control Purchase Price with respect to

foregoing provisions, such Note shall be paid by the Company at the Change of
Control Purchase Price; provided, however, that installments of interest whose
Stated Maturity is on or prior to the Change of Control Purchase Date shall be
payable to the Holders of such Notes, or one or more Predecessor Notes,

Holder's attorney duly authorized in writing), and the Company shall execute and
pursuant to a Company Order the Trustee shall authenticate and deliver to the
Holder of such Note, without service charge, one or more new Notes of any
authorized denomination as requested by such Holder in an aggregate principal
amount equal to, and in exchange for, the portion of the principal amount of the
Note so surrendered that is not purchased.

Control Purchase Date, accept for payment of Notes or portion thereof tendered
pursuant to the Change of Control Offer, (ii) not later than 11:00 a.m. (New

accepted payment in an amount equal to the Change of Control Purchase Price of
the Notes purchased from each such Holder. Any Notes not so accepted shall be
promptly mailed or delivered by the Paying Agent at the Company's expense to the
Holder thereof. The Company will publicly announce the results of the Change of
Control Offer on the Change of Control Purchase Date. For purposes of this
Section, the Company shall choose a Paying Agent which shall not be the Company.

                  (e)      A tender made in response to a Change of Control
Purchase Notice may be withdrawn before or after delivery by the Holder to the
Paying Agent at the office of the Paying Agent of the Notes to which such Change
of Control Purchase Notice relates, by means of a written notice of withdrawal
delivered by the Holder to the Paying Agent at the office of the Paying Agent or
to the office or agency referred to in Section 10.02 to which the related Change
of Control Purchase Notice was delivered not later than three Business Days
prior to the Change of Control Purchase Date specifying as applicable:

         $1,000 or an integral multiple thereof) delivered for purchase by the
         Holder as to which such notice of withdrawal is being submitted;

                  (4)      a statement that such Holder is withdrawing such
         Holder's election to have such principal amount of such Note purchased;
         and

                  (5)      the principal amount, if any, of such Note (which
         shall be $1,000 or an integral multiple thereof) that remains subject
         to the original Change of Control Purchase Notice and that has been or
         will be delivered for purchase by the Company.

                  (f)      As provided in the Notes, the Trustee and the Paying
Agent shall return to the Company any cash that remains unclaimed, together with
interest or dividends, if any, thereon, held by either of them for the payment
of the Change of Control Purchase Price; provided, however, that (x) to the
extent that the aggregate amount of cash deposited by the Company pursuant to
clause (ii) of paragraph (d) above exceeds the aggregate Change of Control
Purchase Price of the Notes or portions thereof to be purchased, then the
Trustee or the Paying Agent shall hold such excess for the Company and (y)
unless otherwise directed by the Company in writing, promptly after the Business
Day following the Change of Control Purchase Date, the Trustee or the Paying
Agent shall return any such excess to the Company together with interest, if
any, thereon.

                  (g)      The Company shall comply with the applicable tender
offer rules, including Rule 14e-1 under the Exchange Act, and any other
applicable securities laws or regulations in connection with a Change of Control
Offer.

                                                                              91

                  (h)      Notwithstanding the occurrence of a Change of
Control, the Company shall not be obligated to repurchase the Notes pursuant to
a Change of Control Offer, or otherwise comply with this Section, if the Company
has elected to redeem all of the Notes in accordance with Article XI.

                  The Company shall not, and shall not permit any Subsidiary to,
create or permit to exist or become effective any restriction that would
expressly impair the ability of the Company to make a Change of Control Offer to
purchase the Notes or, if such Change of Control Offer is made, to pay for the
Notes tendered for purchase.

                  SECTION 10.15. Limitation on Issuance and Sale of Capital
Stock of Restricted Subsidiaries. The Company will not permit:

                  (a)      any Restricted Subsidiary to issue any Capital Stock
         (other than to the Company or any Restricted Subsidiary); or

                  (b)      any Person (other than the Company or a Restricted
         Subsidiary) to acquire any Capital Stock of any Restricted Subsidiary
         from the Company or any Restricted Subsidiary,

except if, immediately after giving effect to such issuance or sale, such
Restricted Subsidiary would continue to be a Restricted Subsidiary or if,
immediately after giving effect to such issuance or sale, such Restricted
Subsidiary would no longer be a Restricted Subsidiary and the Company's
Investment in such Person after giving effect to such issuance or sale would
have been permitted to be made under the provisions of Section 10.09 as if made
on the date of such issuance or sale (and such Investment shall be deemed to be
an Investment made for the purposes of Section 10.09). The proceeds of any
issuance or sale of such Capital Stock permitted hereby will be treated as Net
Cash Proceeds from an Asset Sale and must be applied in accordance with the
terms of Section 10.13 (including the limitation noted in paragraph (f)
thereof). Notwithstanding the foregoing, no issuance or sale of any Capital
Stock of NBI (other than to the Company or any other Restricted Subsidiary)
shall be permitted.

                  SECTION 10.16. Limitation on Dividends and Other Payment
Restrictions Affecting Restricted Subsidiaries. The Company will not, and will
not permit any of its Restricted Subsidiaries to, directly or indirectly, create
or otherwise cause or suffer to exist or become effective any encumbrance or
restriction on the ability of any Restricted Subsidiary to (a) pay dividends or
make any other distribution on its Capital Stock to the Company or any other
Restricted Subsidiary, (b) pay any Indebtedness owed to the Company or any other
Restricted Subsidiary, (c) make any Investment in the Company or (d) transfer
any of its properties or assets to the Company or any Restricted Subsidiary,
except (i) any encumbrance or restriction pursuant to or in connection with any
agreement as in effect on the date of this Indenture, (ii) any encumbrance or
restriction, with respect to a Restricted Subsidiary that is not a Restricted
Subsidiary of the Company on the date of this Indenture, in existence at the
time such Person becomes a Restricted Subsidiary of the Company and not Incurred
in connection with, or in contemplation of, such Person becoming a Restricted
Subsidiary, (iii) customary provisions restricting subletting or assignment of

Subsidiary and (iv) any encumbrance or restriction existing under

                                                                              92

any amendments, modifications, restatements, renewals, supplements, replacements
or refinancings of the agreements containing the encumbrances or restrictions in
the foregoing clauses (i) and (ii); provided that the terms and conditions of
any such encumbrances or restrictions, taken as a whole, are not materially less
favorable to the Holders than those under or pursuant to the agreement
evidencing the Indebtedness so extended, renewed, refinanced or replaced.

                  SECTION 10.17. Provision of Financial Statements. Whether or
not the Company or RMI is subject to Section 13(a) or 15(d) of the Exchange Act,
the Company and RMI will, to the extent permitted under the Exchange Act, file
with, or furnish to, the Commission the annual reports and other documents that
they would have been required to file with, or furnish to, the Commission
pursuant to such Section 13(a) or 15(d), including any information relating to
the Company and RMI as may be required by Regulation S-X under the Exchange Act
or by the Commission, if they were so subject, such documents to be filed with,
or furnished to, the Commission on or prior to the respective dates (the
"Required Filing Dates") by which they would have been required so to file, or
to furnish, such documents if they were so subject; provided that if and for so
long as RMI is no longer subject to Section 13(a) or 15(d) of the Exchange Act,
RMI may satisfy its obligations under this paragraph through the inclusion in
the Company's annual reports and other documents filed with or furnished to the
Commission pursuant to Section 13(a) or 15(d) of the Exchange Act (or these
provisions of this Indenture) of audited annual and unaudited quarterly
financial statements for RMI prepared in accordance with GAAP, and reconciled to
United States GAAP; provided further that at such time as RMI may become a 100%
owned Restricted Subsidiary of the Company, RMI may satisfy its obligations
under this paragraph through the inclusion in a footnote to the Company's
consolidated financial statements of financial information for RMI, any other
Guarantors of the Notes that are Subsidiaries of the Company and any
non-Guarantor Subsidiaries, equivalent to that which would be required under
Rule 3-10 of Regulation S-X. The Company will in any event (x) within 15 days of
such Required Filing Date (i) transmit by mail to all Holders, as their names
and addresses appear in the Note Register, without cost to such Holders and (ii)
file with the Trustee copies of the annual reports and other documents
(including the audited annual market value financial statements described above)
which the Company and RMI would have been required to file with, or to furnish
to, the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act if
they were subject to such Sections (subject to the proviso set forth in the
immediately preceding sentence) and (y) if filing or furnishing such documents
by the Company or RMI 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
Holders at the Company's cost.

                  SECTION 10.18. Statement by Officers as to Default. (a) The
Company and RMI will deliver to the Trustee, on or before a date not more than
45 days after the end of each fiscal quarter and not more than 90 days after the
end of each fiscal year of the Company and RMI ending after the date hereof, a
written statement signed by two executive officers of each of the Company and
RMI, one of whom shall be the principal executive officer, principal financial
officer or principal accounting officer of the Company and RMI, as applicable,
stating whether or not, after a review of the activities of the Company and RMI
during such year or such quarter and of the Company's and RMI's performance
under this Indenture, to the best knowledge, based on such review, of the
signers thereof, each of the Company and RMI has fulfilled all its

                                                                              93

respective obligations and is in compliance with all conditions and covenants
under this Indenture throughout such year or quarter, as the case may be, and,
if there has been a Default, specifying each Default and the nature and status
thereof.

                  (b)      When any Default or Event of Default has occurred and
is continuing, or if the Trustee or any Holder or the trustee for or the holder
of any other evidence of Indebtedness of the Company or any Restricted
Subsidiary gives any notice or takes any other action with respect to a claimed
default, the Company shall deliver to the Trustee by registered or certified
mail or by telegram, telex or facsimile transmission followed by hard copy an
Officers' Certificate specifying such Default, Event of Default, notice or other
action, the status thereof and what action the Company is taking or proposes to
take with respect thereto, within five Business Days of its occurrence.

                  SECTION 10.19. Waiver of Certain Covenants. The Company may
omit in any particular instance to comply with any covenant or condition set
forth in Sections 10.05 through 10.13 and Sections 10.15 through 10.18 if,
before or after the time for such compliance, the Holders of not less than a
majority in aggregate principal amount of the Notes at the time Outstanding
waive such compliance in such instance with such covenant or condition, but no
such waiver shall extend to or affect such covenant or condition except to the
extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such
covenant or condition shall remain in full force and effect.

                  SECTION 10.20. Limitation on the Designation of Unrestricted
Subsidiaries. (a) The Board of Directors may designate any Restricted Subsidiary
as an Unrestricted Subsidiary if (i) such action is in compliance with Section
10.09 of this Indenture and (ii) such action complies with the definition of
"Unrestricted Subsidiaries."

                  (b)      The Board of Directors may not designate any
Unrestricted Subsidiary as a Restricted Subsidiary unless any additional
Indebtedness incurred as a result of giving effect to such action (and treating
any Acquired Indebtedness as having been incurred at the time of such action)
would constitute Permitted Indebtedness.

                  SECTION 10.21. Additional Amounts. (a) All payments made by
the Company or any of the Note Guarantors under or with respect to the Notes
shall be made free and clear of and without withholding or deduction for or on
account of any present or future tax, duty, levy, impost, assessment or other
governmental charge (including penalties, interest and other liabilities related
thereto) (hereinafter "Taxes") imposed or levied by or on behalf of the
government of Canada or any political subdivision or any authority or agency
therein or thereof having power to tax, or within any other jurisdiction in
which the Company or any such Note Guarantor is organized or is otherwise
resident for tax purposes or any jurisdiction from or through which payment is
made (each a "Relevant Taxing Jurisdiction"), unless it is required to withhold
or deduct Taxes by law or by the interpretation or administration thereof.

                  (b)      If the Company or any Note Guarantor is so required
to withhold or deduct any amount for or on account of Taxes imposed by a
Relevant Taxing Jurisdiction from any payment made under or with respect to the
Notes, it will be required to pay such additional

                                                                              94

<PAGE>

amounts ("Additional Amounts") as may be necessary so that the net amount
received by Holders (including Additional Amounts) after such withholding or
deduction will not be less than the amount that such Holders would have received
if such Taxes had not been withheld or deducted; provided, however, that the
foregoing obligation to pay Additional Amounts does not apply (1) with respect
to a payment made to a Holder (an "Excluded Holder") (A) with which the Company
or such Note Guarantor does not deal at arm's length (within the meaning of the
Income Tax Act (Canada)) at the time of making such payment, or (B) which is
subject to any Taxes by reason of the existence of any present or former
connection between the relevant Holder (or between a fiduciary, settlor,
beneficiary, member or shareholder of, or possessor of power over the relevant
Holder, if the relevant Holder is an estate, nominee, trust or corporation) and
the Relevant Taxing Jurisdiction (other than the mere receipt of such payment or
the ownership or holding outside of Canada of such Note); or (2) to any estate,
inheritance, gift, sales, excise, transfer, personal property tax or similar
tax, assessment or governmental charge ("Excluded Taxes"); nor will the Company
or any Note Guarantor pay Additional Amounts if the payment could have been made
without such deduction or withholding if the beneficiary of the payment had
presented the Note for payment within 30 days after the date on which such
payment or such Note became due and payable or the date on which payment thereof
is duly provided for, whichever is later (except to the extent that the Holder
would have been entitled to Additional Amounts had the Note been presented on
the last day of such 30-day period).

                  (c)      The Company and each Note Guarantor will also (i)
make such withholding or deduction and (ii) remit the full amount deducted or
withheld to the relevant authority in accordance with applicable law. The
Company and each Note Guarantor will furnish to the Holders, within 30 days
after the date the payment of any Taxes is due pursuant to applicable law,
certified copies of tax receipts evidencing such payment by the Company or such
Note Guarantor. The Company and each Note Guarantor will indemnify and hold
harmless each Holder (other than an Excluded Holder or with respect to Excluded
Taxes) and upon written request will reimburse each such Holder for the amount
of (1) any Taxes so levied or imposed and paid by such Holder as a result of
payments made under or with respect to the Notes and (2) any Taxes levied or
imposed and paid by such Holder with respect to any reimbursement under clause
(1), but excluding any such Taxes on such Holder's income or net income.

                  (d)      At least 30 days prior to each date on which any
payment under or with respect to the Notes is due and payable, if the Company or
the Note Guarantors will be obligated to pay Additional Amounts with respect to
such payment, the Company and the Note Guarantors will deliver to the Trustee an
Officers' Certificate stating the fact that such Additional Amounts will be
payable and the amounts so payable, and will set forth such other information
necessary to enable the Trustee to pay such Additional Amounts to Holders on the
payment date.

                  (e)      Whenever in this Indenture there is mentioned, in any
context: (1) the payment of principal; (2) purchase prices in connection with a
purchase of Notes; (3) interest; or (4) any other amount payable on or with
respect to any of the Notes, such reference shall be deemed to include payment
of Additional Amounts as described under this heading to the extent that, in
such context, Additional Amounts are, were or would be payable in respect
thereof.

                  (f)      The Company and the Note Guarantors will pay any
present or future stamp, court or documentary taxes or any other excise or
property taxes, charges or similar levies

                                                                              95

<PAGE>

that arise in any jurisdiction from the execution, delivery, enforcement or
registration of the Notes, this Indenture or any other document or instrument in
relation thereof, or the receipt of any payments with respect to the Notes,
excluding such taxes, charges or similar levies imposed by any jurisdiction
outside of Canada, the jurisdiction of incorporation of any successor of the
Company or any of the Note Guarantors or any jurisdiction in which a paying
agent is located, and the Company and the Note Guarantors will agree to
indemnify the Holders for any such taxes paid by such Holders.

                  (g)      The obligations of the Company and the Note
Guarantors under this Section 10.21 will survive any termination, defeasance or
discharge of this Indenture and will apply mutatis mutandis to any jurisdiction
in which any successor Person to the Company or any Note Guarantor, as
applicable, is organized or any political subdivision or taxing authority or
agency thereof or therein.

                  SECTION 10.22. Covenants of RMI, RCL and Sugra. (a) RMI hereby
covenants not to assign the Services Agreement to any other party, other than
(i) pursuant to the pledge of the Services Agreements to the Trustee and the
Collateral Agent under this Indenture and the Security Documents or (ii) a
Permitted Transfer. Additionally, RMI hereby covenants that, for so long as any
of the Notes is outstanding, RMI will not form any other vehicle that would be
used to provide the same services to Hollinger International and its
Subsidiaries as those currently provided under the Services Agreements.

                  (b)      RCL hereby covenants to vote its Capital Stock in
RMI, and cause any subsequent holder of Capital Stock of RMI to vote such stock,
so as to cause RMI to comply with its obligations under this Indenture, its
Guarantee, the Support Agreement, the Security Documents and other transaction
agreements. Additionally, RCL hereby covenants that, for so long as any of the
Notes is outstanding, RCL will not form any other vehicle that would be used to
provide the same services to Hollinger International and its Subsidiaries as
those currently provided under the Services Agreements. These covenants of RCL
will not be deemed to be a guarantee by RCL of the Notes.

                  (c)      Sugra hereby covenants that, until and unless the NBI
Guarantee shall have been released in accordance with this Indenture, it will
not create, Incur, assume or suffer to exist any Lien on any of its shares of
Capital Stock of NBI. This covenant of Sugra will not be deemed to be a
guarantee by Sugra of the Notes.

                  SECTION 10.23. Limitation on RMI's Business Activities. RMI
shall not:

                  (a)      Incur any Indebtedness other than its Guarantee of
         the Notes (and any refinancings or replacements thereof permitted under
         the definition of "Permitted Indebtedness");

                  (b)      Create, Incur, assume or suffer to exist any Lien on
         any of its assets or properties of any character; or

                  (c)      engage in any business activities other than (i) the
         issuance of the RMI Guarantee, (ii) the performance of its obligations
         and pursuit of its rights under the Services Agreements, the Support
         Agreement and the Contribution Agreement or its

                                                                              96

         rights and obligations existing on the date hereof, (iii) the
         transactions contemplated in paragraph (vi) of Section 10.10, and (iv)
         activities incidental to those described in this clause (c).

                               Redemption of Notes

         1, 2007, subject to the conditions and at the Redemption Prices
         specified in the form of Note or in this Indenture and any Indenture
         supplemental hereto with respect to the Notes as provided in Exhibit A,
         together with accrued and unpaid interest, if any, to the Redemption
         Date (subject to the right of Holders of record of the Notes on
         relevant Regular Record Dates and Special Record Dates to receive
         interest due on relevant Interest Payment Dates) to the extent that
         this Article does not conflict with the terms of the form of Note;

                  (b)      prior to March 1, 2006, on one or more occasions to
         redeem the Notes in an aggregate principal amount not to exceed 35% of
         the aggregate principal amount of the Notes originally issued at a
         Redemption Price (expressed as a percentage of principal amount) of
         111.875%, plus accrued and unpaid interest to the Redemption Date, with
         the net cash proceeds contributed to the Company from one or more
         Public Equity Offerings; and

                  (c)      as a whole and not in part, upon not less than 30 nor
         more than 60 days' notice, at any time, at a Redemption Price equal to
         the principal amount thereof plus accrued interest to the date fixed
         for redemption only if, as a result of (1) any change in or amendment
         to the laws of Canada (or of any political subdivision or taxing
         authority therein or thereof) or any regulations or rulings promulgated
         thereunder or any change in the official interpretation or official
         application of such laws, regulations or rulings (including a judgment,
         holding or order by a court of competent jurisdiction), or (2) any
         change in the official application or interpretation (including a
         judgment, holding or order by a court of competent jurisdiction) of, or
         any execution of or amendment to, any treaty or treaties affecting
         taxation to which Canada (or such political subdivision or taxing
         authority) is a party, which change, amendment or treaty becomes
         effective on or after the date of this Indenture:

                           (i)      the Company is or would be required on the
                  next succeeding due date for a payment with respect to the
                  Notes to pay any Additional Amounts with respect to the Notes
                  pursuant to Section 10.21, or

                           (ii)     with respect to any payment due or to become
                  due under the Guarantees or this Indenture, RMI or NBI is, or
                  on the next succeeding due date with respect to the Notes
                  would be, required to pay any Additional Amounts pursuant to
                  Section 10.21.

                                                                              97

<PAGE>

                  SECTION 11.02. Applicability of Article. Redemption of Notes
at the election of the Company or otherwise, as permitted or required by any
provision of this Indenture, shall be made in accordance with such provision and
this Article.

                  SECTION 11.03. Election to Redeem; Notice to Trustee. The
election of the Company to redeem any Notes pursuant to Section 11.01 shall be
evidenced by a Company Order and an Officers' Certificate stating that the
Company is entitled to effect such redemption and setting forth a statement of
facts showing that the conditions precedent to the right of redemption have
occurred. In case of any redemption at the election of the Company, the Company
shall, not less than 30 nor more than 60 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 Notes to be redeemed.

                  SECTION 11.04. Selection by Trustee of Notes to be Redeemed.
(a) If less than all the Notes are to be redeemed, the portions of the Notes to
be redeemed shall be selected not more than 60 days prior to the Redemption Date
by the Trustee (or such shorter period as the Trustee may agree upon), from the
Outstanding Notes not previously called for redemption, by lot or such other
method as the Trustee shall deem fair and reasonable, and the amounts to be
redeemed may be equal to $1,000 or any integral multiple thereof, unless
otherwise provided in the terms of the Notes.

                  (b)      The Trustee shall promptly notify the Company and the
Note Registrar in writing of the Notes selected for redemption and, in the case
of Notes selected for partial redemption, the principal amount thereof to be
redeemed.

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

                  SECTION 11.05. Notice of Redemption. (a) Notice of redemption
shall be given by first-class mail, postage prepaid, mailed not less than 30 nor
more than 60 days prior to the Redemption Date, to each Holder of Notes to be
redeemed, at his address appearing in the Note Register. All notices of
redemption shall state:

                  (i)      the Redemption Date;

                  (ii)     the Redemption Price;

                  (iii)    if less than all the Outstanding Notes are to be
         redeemed, the identification of the particular Notes to be redeemed;

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

                                                                              98

<PAGE>

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

                  (vi)     that on the Redemption Date the Redemption Price will
         become due and payable upon each such Note 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;

                  (vii)    the place or places where such Notes are to be
         surrendered for payment of the Redemption Price; and

                  (viii)   the CUSIP number, if any, relating to such Notes.

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

                  (c)      Such 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 Note designated for redemption as a
whole or in part shall not affect the validity of the proceedings for the
redemption of any other Note.

                  SECTION 11.06. Deposit of Redemption Price. Prior to 11:00
a.m., New York City time, on any Redemption Date, the Company shall irrevocably
deposit with the Trustee or with a Paying Agent 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, accrued interest on, all the Notes or
portions thereof which are to be redeemed on that date. The Trustee or the
Paying Agent shall hold in trust for, and return to, the Company promptly after
the Business Day following the Redemption Date any interest or dividends, if
any, earned on amounts deposited with the Trustee or the Paying Agent remaining
after the payment of the aggregate Redemption Price for all Notes to be
redeemed; provided that neither the Trustee nor the Paying Agent shall be under
any obligation to place or invest such funds in an interest bearing account.

                  SECTION 11.07. Notes Payable on Redemption Date. (a) Notice of
redemption having been given as aforesaid, the Notes 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 not have
deposited funds in accordance with Section 11.06 in respect of the payment of
the Redemption Price and accrued interest) such Notes shall cease to bear
interest. Upon surrender of any such Note for redemption in accordance with said
notice, such Note shall be paid by the Company at the Redemption Price together
with accrued interest to the Redemption Date; provided, however, that
installments of interest whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Notes, or one or more Predecessor
Notes, registered as such on the relevant Regular Record Dates according to the
terms and the provisions of Section 3.08.

                                                                              99

<PAGE>

                  (b)      If any Note called for redemption shall not be so
paid upon surrender thereof for redemption, by deposit or segregation of funds
in accordance with Section 11.06, the principal and premium, if any, shall,
until paid, bear interest from the Redemption Date at the rate then borne by
such Note.

                  SECTION 11.08. Notes Redeemed or Purchased in Part. Any Note
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 10.02 (with, if the Company, the Note Registrar or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company, the Note 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 pursuant to a Company
Order the Trustee shall authenticate and deliver to the Holder of such Note
without service charge, a new Note or Notes, 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 Note so surrendered that is

Independent Obligation. (a) Each of the Guarantees shall be a continuing

and counsel) or the Holders; and neither of the Guarantees shall be considered
as wholly or partially satisfied by the payment or liquidation at any time or

to the Trustee or the Holders. Each of the Note Guarantors covenants and agrees
to comply with all obligations, covenants, agreements and provisions applicable
to it in this Indenture including those set forth in Article VIII and Section
10.17. Without limiting the generality of the foregoing, each of the Note
Guarantors' liability shall extend to all amounts which constitute part of the
Indenture Obligations and would be owed by the Company under this Indenture and
the Notes but for the fact that they are unenforceable, reduced, limited,
impaired, suspended or not allowable due to the existence of a bankruptcy,
reorganization or similar proceeding involving the Company.

                  (d)      Each of the Note Guarantors' liability to pay or
perform or cause the performance of the Indenture Obligations under the
Guarantees shall arise forthwith after demand for payment or performance by the
Trustee has been given to such Note Guarantor in accordance with the terms
hereof and in the manner prescribed in Section 1.06 hereof.

                  (e)      Except as provided herein, the provisions of this
Article XIII cover all agreements between the parties hereto relative to the
Guarantees and none of the parties shall be bound by any representation,
warranty or promise made by any Person relative thereto which is not embodied
herein; and it is specifically acknowledged and agreed that the Guarantees have
been delivered by each of the Note Guarantors free of any conditions whatsoever
and that no representations, warranties or promises have been made to any of the
Note Guarantors affecting their liabilities hereunder, and that the Trustee
shall not be bound by any representations, warranties or promises now or at any
time hereafter made by the Company to either of the Note Guarantors.

                  SECTION 13.03. Guarantees Absolute. The obligations of each of
the Note Guarantors hereunder are independent of the obligations of the Company
under the Notes and this Indenture and a separate action or actions may be
brought and prosecuted against any of the

                                                                             102

released, discharged, mitigated, waived, impaired or affected in whole or in
part by:

         the Note Guarantors or any other Person or from perfecting, continuing
         to keep perfected or taking advantage of any security;

                  (f)      any loss, diminution of value or lack of

         Guarantors or any other Person, and including any other guarantees

         Guarantors or any other Person, or with any security;

         time or from time to time, or any manner of application of collateral,
         or proceeds thereof, to all or any of the Indenture Obligations, or the
         manner of sale of any Collateral;

                                                                             103

         Guarantors or of any other Guarantor of the Notes or of any Person
         liable directly as surety or otherwise by operation of law or otherwise

         reorganization affecting the Company or the Note Guarantors;

                  (p)      any other circumstance (including any statute of
         limitations) that might otherwise constitute a defense available to, or
         discharge of, the Company or the Note Guarantors; or

                  (q)      any modification, compromise, settlement or release
         by the Trustee, or by operation of law or otherwise, of the Indenture
         Obligations or the liability of the Company or any other obligor under
         the Notes, or of any Collateral, in whole or in part, and any refusal

                  SECTION 13.04. Right to Demand Full Performance. In the event
of any demand for payment or performance by the Trustee from any of the Note

Guarantors, be considered as a purchase of such security, or as payment,
satisfaction or reduction of the Indenture Obligations due to the Trustee or the
Holders by the Company or any part thereof.

                  SECTION 13.05. Waivers. (a) Each of the Note Guarantors hereby
expressly waives (to the extent permitted by law) notice of the acceptance of
this Guarantee and notice of the existence, renewal, extension or the
nonperformance, nonpayment, or nonobservance on the part of the Company of any
of the terms, covenants, conditions and provisions of this Indenture or the
Notes or any other notice whatsoever to or upon the Company or the Note
Guarantors with respect to the Indenture Obligations. Each of the Note
Guarantors hereby acknowledges communication to it of the terms of this
Indenture and the Notes and all of the provisions therein contained and consents
to and approves the same. Each of the Note Guarantors hereby expressly waives
(to the extent permitted by law) diligence, presentment, protest, and any right
to require a proceeding first against the Company.

                  (b)      Without prejudice to any of the rights or recourses
which the Trustee or the Holders may have against the Company, each of the Note
Guarantors hereby expressly waives (to the extent permitted by law) any right to
require the Trustee or the Holders to:

                  (i)      initiate or exhaust any rights, remedies or recourse
         against the Company, the Note Guarantors or any other Person;

                  (ii)     value, realize upon, or dispose of any security of
         the Company or any other Person held by the Trustee or the Holders; or

                  (iii)    initiate or exhaust any other remedy which the
         Trustee or the Holders may have in law or equity;

before requiring or becoming entitled to demand payment from any Note Guarantor
under this Guarantee.

                  SECTION 13.06. Note Guarantors Remain Obligated in Event the
Company Is No Longer Obligated to Discharge Indenture Obligations. It is the
express intention of the Trustee and the Note Guarantors that if for any reason
the Company has no legal existence, is or becomes under no legal obligation to
discharge the Indenture Obligations owing to the Trustee or the Holders by the
Company or if any of the Indenture Obligations owing by the Company to the
Trustee or the Holders becomes irrecoverable from the Company by operation of
law or for any reason whatsoever, the Guarantees and the covenants, agreements
and obligations of the Note Guarantors contained in this Article XIII shall
nevertheless be binding upon the Note Guarantors, as principal debtors, until
such time as all such Indenture Obligations have been paid in full to the
Trustee and all Indenture Obligations owing to the Trustee or the Holders by the
Company have been discharged, or such earlier time as Section 4.02 shall apply
to the Notes and the Note Guarantors shall be responsible for the payment
thereof to the Trustee or the Holders upon demand.

                  SECTION 13.07. Waiver of Rights. Each of the Note Guarantors
agrees (to the extent permitted by law) that it hereby waives and will not in
any manner whatsoever claim or take the benefit or advantage of, any rights of
reimbursement, exoneration, contribution,

                                                                             105

indemnity or subrogation (whether contractual, under Section 509 of Title Eleven
of the United States Code, under common law or otherwise) or any similar rights
or "claims" (as such term is defined under Title Eleven of the United States
Code), against the Company or any Restricted Subsidiary arising from the
existence of, or performance by, the Note Guarantors under this Guarantee, until
such time as the Indenture Obligations have been paid in full.

                  SECTION 13.08. Guarantees Are in Addition to Other Security.
The Guarantees shall be in addition to and not in substitution for any other
guarantees or other security which the Trustee may now or hereafter hold in
respect of the Indenture Obligations owing to the Trustee or the Holders by the
Company and (except as may be required by law) the Trustee shall be under no
obligation to marshal in favor of the Note Guarantors any other guarantees or
other security or any moneys or other assets which the Trustee may be entitled
to receive or upon which the Trustee or the Holders may have a claim.

                  SECTION 13.09. Release of Security Interests. Without limiting
the generality of the foregoing and except as otherwise provided in this
Indenture, each of the Note Guarantors hereby consents and agrees, to the
fullest extent permitted by applicable law, that the rights of the Trustee
hereunder, and the liability of each of the Note Guarantors hereunder, shall not
be affected by any and all releases for any purpose of any Collateral, if any,
from the Liens and security interests created by any document relating thereto
and that this Guarantee shall continue to be effective or be reinstated, as the
case may be, if at any time any payment of any of the Indenture Obligations is
rescinded or must otherwise be returned by the Trustee upon the insolvency,
bankruptcy or reorganization of the Company or otherwise, all as though such
payment had not been made. Notwithstanding any of the foregoing, NBI shall be
released from its obligations as Note Guarantor upon the Company's request if
all of the Designated Class A Shares and Class B Shares owned by NBI and pledged
as part of the Pledged Share Collateral have been released from the security
interest in favor of the Collateral Agent as permitted by and in accordance with
the provisions of this Indenture and/or the Security Agreement.

                  SECTION 13.10. No Bar to Further Actions. Except as provided
by law, no action or proceeding brought or instituted under this Article XIII
and this Guarantee and no recovery or judgment in pursuance thereof shall be a
bar or defense to any further action or proceeding which may be brought under
this Article XIII and this Guarantee by reason of any further default or
defaults under this Article XIII and this Guarantee or in the payment of any of
the Indenture Obligations owing by the Company.

                  SECTION 13.11. Failure to Exercise Rights Shall Not Operate as
a Waiver; No Suspension of Remedies. (a) No failure to exercise and no delay in
exercising, on the part of the Trustee or the Holders, any right, power,
privilege or remedy under this Article XIII and this Guarantee shall operate as
a waiver thereof, nor shall any single or partial exercise of any rights, power,
privilege or remedy preclude any other or further exercise thereof, or the
exercise of any other rights, powers, privileges or remedies. The rights and
remedies herein provided for are cumulative and not exclusive of any rights or
remedies provided in law or equity.

                  (b)      Nothing contained in this Article XIII shall limit
the right of the Trustee or the Holders to take any action to accelerate the
maturity of the Notes pursuant to Article V or to pursue any rights or remedies
hereunder or under applicable law.

                                                                             106

<PAGE>

                  SECTION 13.12. Trustee's Duties; Notice to Trustee. (a) Any
provision in this Article XIII or elsewhere in this Indenture allowing the
Trustee to request any information or to take any action authorized by, or on
behalf of a Note Guarantor, shall be permissive and shall not be obligatory on
the Trustee except as the Holders may direct in accordance with the provisions
of this Indenture.

                  (b)      The Trustee shall not be required to inquire into the
existence, powers or capacities of the Company, the Note Guarantors or the
officers, directors or agents acting or purporting to act on their respective
behalf.

                  (c)      Notwithstanding the provisions of this Article XIII
or any other provision of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts which would prohibit the making of any
payment to or by the Trustee in respect of the Notes, unless and until the
Trustee shall have received written notice thereof from a Note Guarantor; and,
prior to the receipt of any such written notice, the Trustee, subject to the
provisions of Section 6.01, shall be entitled in all respects to assume that no
such facts exist; provided, however, that if the Responsible Officer of the
Trustee shall not have received any such notice from a Note Guarantor at least
three Business Days prior to the date upon which by the terms hereof any money
may become payable for any purpose (including, without limitation, the payment
of the principal of, premium, if any, or interest on any Note), then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full
power and authority to receive such money and to apply the same to the purpose
for which such money was received and shall not be affected by any notice to the
contrary which may be received by it within three Business Days prior to such
date; nor shall the Trustee be charged with knowledge of the curing of any such
default or the elimination of the act or condition preventing any such payment
unless and until the Responsible Officer of the Trustee shall have received an
Officers' Certificate to such effect.

                  (d)      In the case at any time any Paying Agent other than
the Trustee shall have been appointed by the Company and be then acting
hereunder, the term "Trustee" as used in this Article XIII shall in such case
(unless the context otherwise requires) be construed as extending to and
including such Paying Agent within its meaning as fully for all intents and

to the Company or any Affiliate of the Company if the Company or such Affiliate
acts as Paying Agent.

any documents reasonably required in order to evidence the release of each Note
Guarantor from its obligations under the Guarantees. If any of the Indenture
Obligations are revived and reinstated after the termination of the Guarantees,

revived and reinstated as if this Guarantee had not been terminated until such
time as the Indenture Obligations are paid in full, and the Note Guarantors
shall enter into an amendment to this Guarantee, reasonably satisfactory to the
Trustee, evidencing such revival and reinstatement.

         Documents, or (b) stating that, in the opinion of such counsel, no such
         action is necessary to maintain such Lien and assignment.

         the Cash Collateralized Notes on the Stated Maturity, such number of
         Designated Class A Shares and/or Class B Shares as the Company may

         Cash Collateralized Notes to the original principal amount of Notes
         issued on the Issue Date, provided that the total number of Designated
         Class A Shares and Class B Shares comprising the Pledged Share

         consent to the release of their Lien in the Senior Notes Collateral.

                  (b)      The release of any portion of the Senior Notes
Collateral from the Lien under this Indenture and the Security Documents
pursuant to the terms hereof and of the Security Documents will not be deemed
to impair the security interest under this Indenture in contravention of the
provisions hereof. To the extent applicable, the Company and the Note
Guarantors shall cause Trust Indenture Act Section 314(d) relating to the
release of property from the Lien under the Security Documents to be complied
with. Any certificate or opinion required by Trust Indenture Act Section 314(d)
may be made by an Officer of the Company, except in cases in which Trust
Indenture Act Section 314(d) requires that such certificate or opinion be made
by an independent Person.

                  SECTION 14.05. Enforcement of Claims Against Collateral. If
the Notes become due and payable prior to their final Stated Maturity for any
reason or are not paid in full at the final Stated Maturity and no payment has
been made following a demand on either of the Guarantees, the Collateral Agent
and the Trustee have the right to foreclose or otherwise realize upon the
relevant Collateral in accordance with instructions from Holders of a majority
in aggregate principal amount of the Notes. The proceeds received by the
Collateral Agent and the Trustee upon a foreclosure or realization will be
applied by the Collateral Agent and the Trustee first to pay the expenses of
such foreclosure or realization and fees and other amounts then payable to the
Collateral Agent and the Trustee under this Indenture, the Intercreditor
Agreement and the Security Documents, and thereafter, to pay all amounts owing
to Holders under this Indenture, the Notes and the Security Documents. Any
remaining proceeds will be payable to the Company or as may otherwise be
required.

                  SECTION 14.06. Authorization of Actions To Be Taken by the
Trustee. Subject to the provisions of the Security Documents and the
Intercreditor Agreement, the Trustee shall have power to institute and to
maintain such suits and proceedings as it may deem expedient to prevent any
impairment of the Senior Notes Collateral by any acts which may be unlawful or
in violation of the Security Documents and the Intercreditor Agreement, or this
Indenture, and such

                                                                             112

<PAGE>

suits and proceedings as the Trustee may deem expedient to preserve or protect
its interests and the interests of the Holders in the Senior Notes Collateral
(including power to institute and maintain suits or proceedings to restrain the
enforcement of or compliance with any legislative or governmental enactment,
rule, or order that may be unconstitutional or otherwise invalid if the
enforcement of, or compliance with, such enactment, rule or order would impair
the security hereunder or be prejudicial to the interest of the Holders or the
Trustee). Notwithstanding anything herein or in any of the Security Documents to
the contrary, subject to Article VI hereof, the Trustee assumes no
responsibility for the validity, perfection, priority or enforceability of the
security interest in any of the Senior Notes Collateral and shall have no
obligation to take any action to procure or maintain such validity, perfection,
priority or enforceability.
