other action provided or permitted by this Indenture to be given, made or taken
by Holders of Securities, provided that the Company may not set a record date

a Holder made by any Person in respect of any such matter referred to in the
foregoing sentence, the record date for any such matter shall be the 30th day
(or, if later, the date of the most recent list of Holders required to be
provided pursuant to Section 7.01) prior to such first solicitation. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities on such record date, and no other Holders, shall be entitled to take
the relevant action, whether or not such Holders remain Holders after such
record date; provided that no such action shall be effective hereunder unless
taken on or prior to the applicable Expiration Date by Holders of the requisite
stated amount at Maturity of Outstanding Securities on such record date. Nothing
in this paragraph shall be construed to prevent the Company from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite stated amount at Maturity of
Outstanding Securities on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Trustee in writing and to each
Holder of Securities in the manner set forth in Section 1.06.

               (f) The Trustee may set any day as a record date for the purpose
of determining the Holders of Outstanding Securities entitled to join in the
giving or making of (1) any Notice of Default, (2) any declaration of
acceleration referred to in Section 5.02, (3) any request to institute
proceedings referred to in Section 5.07(b) or (4) any direction referred to in
Section 5.12. If any record date is set pursuant to this paragraph, the Holders
of Outstanding Securities on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite stated amount at Maturity of
Outstanding Securities on such record date. Nothing in this paragraph shall be
construed to prevent the Trustee from setting a new record date for any action
for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with no action
by any Person be cancelled and of no effect), and nothing in this paragraph
shall be construed to render ineffective any action taken by Holders of the
requisite stated amount at Maturity of Outstanding Securities on the date such
action is taken. Promptly after any record date is set pursuant to this
paragraph, the Trustee, at the Company's expense, shall cause notice of such
record date, the proposed action by Holders and the applicable Expiration Date
to be given to the Company in writing and to each Holder of Securities in the
manner set forth in Section 1.06.

<PAGE>   24

               (g) With respect to any record date set pursuant to this Section,
the party hereto which sets such record date may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in
writing, and to each Holder of Securities in the manner set forth in Section
1.06, on or prior to the existing Expiration Date. If an Expiration Date is not
designated with respect to any record date set pursuant to this Section, the
party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

               (h) Without limiting the foregoing, a Holder entitled hereunder
to take any action hereunder with regard to any particular Security may do so
with regard to all or any part of the stated amount at Maturity of such Security
or by one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such principal amount.

               SECTION 1.05 Notices, Etc., to Trustee and Company.

               Any request, demand, authorization, direction, notice, consent,
waiver or Act of Holders or other document provided or permitted by this

writing to the Trustee by the Company.

               SECTION 1.06 Notice to Holders: Waiver.

               (a) Where this Indenture provides for notice to Holders of any
event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each Holder affected by such event, at his address as it appears in the Security
Register, not later than the latest date (if any), and not earlier than the
earliest date (if any), 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. Where this
Indenture provides for notice in any manner, such notice may be waived in
writing by the Person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such notice. Waivers of
notice by Holders shall be filed with the Trustee, but such filing shall not be
a condition precedent to the validity of any action taken in reliance upon such
waiver.

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

               In any case where any Interest Payment Date, Redemption Date,
Purchase Date or Stated Maturity of any Security shall not be a Business Day,
then (notwithstanding any other provision of this Indenture or of the
Securities) payment of interest or stated amount at Maturity (and 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, Redemption Date or Purchase Date, or at the Stated Maturity, provided that
no interest shall accrue for the period from and after such Interest Payment
Date, Redemption Date or Purchase Date or Stated Maturity, as the case may be.

               SECTION 1.14 Consent to Service; Jurisdiction.

               (a) The Company and the Trustee agree that any legal suit, action
or proceeding arising out of or relating to this Indenture, and the Company
agrees that any legal suit, action or proceeding arising out of or relating to
the Securities, may be instituted in any federal or state court in the Borough
of Manhattan, the City of New York, waives any objection which it may now or
hereafter have to the laying of the venue of any such legal suit, action or
proceeding, waives any immunity from jurisdiction or to service of process in
respect of any such suit, action or proceeding, and irrevocably submits to the
exclusive jurisdiction of any such court in any such suit, action or proceeding.

               (b) The Company hereby designates and appoints Watson, Farley &
Williams, New York, New York as its authorized agent upon which process may be
served in any legal suit, action or proceeding arising out of or relating to
this Indenture or the Securities which may be instituted in any federal or state
court in the Borough of Manhattan, the City of New York, New York, and agrees
that service of process upon such agent, and written notice of said service to
the Company by the Person serving the same, shall be deemed in every respect
effective service of process upon the Company in any such suit, action or
proceeding and further designates its domicile, the domicile of New York, New
York specified above and any domicile it may have in the future as its domicile
to receive any notice hereunder (including service of process). Service of
process, to be effective upon the Trustee, must be served at the Trustee's
Corporate Trust Office in The City of New York. If for any reason Watson, Farley
& Williams, New York, New York (or any successor agent for this purpose) shall
cease to act as agent for service of process as provided above, the Company will
promptly appoint a successor agent for this purpose reasonably acceptable to the
Trustee. The Company agrees to take any and all actions as may be necessary to
maintain such designation and appointment of such agent in full force and
effect.

               SECTION 1.15 Conversion of Currency.

               The Company covenants and agrees that the following provisions
shall apply to conversion of currency in the case of the Securities and this
Indenture in the event the Company is in default under the terms of this
Indenture:

               (a) If for the purpose of obtaining judgment in, or enforcing the
judgment of, any court in any country, it becomes necessary to convert into a
currency (the "judgment currency") an amount due in U.S. Dollars, then the
conversion shall be made at the rate of exchange prevailing on the Business Day
before the day on which the judgment is given or the order of enforcement is
made, as the case may be (unless a court shall otherwise determine).

               (b) If there is a change in the rate of exchange prevailing
between the Business Day before the day on which the judgment is given or an
order of enforcement is made, as the case may be (or such other date as a court
shall determine), and the date of receipt of the amount due, the Company will
pay such additional amount (or, as the case may be, be refunded such lesser
amount), if any, as may be necessary so that the amount paid in the judgment
currency when converted at the rate of exchange prevailing on the date of
receipt will produce the amount in U.S. Dollars originally due.

               (c) In the event of the winding-up of the Company at any time
while any amount or damages owing under the Securities of this Indenture, or any
judgment or order rendered in respect thereof, shall remain outstanding, the
Company shall indemnify and hold the Holders and the Trustees harmless against
any deficiency arising or resulting from any variation in rates of exchange
between (1) the date as of which the equivalent of the amount in U.S. Dollars
due or contingently due under the Securities and this Indenture (other than
under this Subsection (c)) is calculated for the purposes of such

                                       19
<PAGE>   27

winding-up and (2) the final date for the filing of proofs of claim in such
winding-up. For the purpose of this Subsection (c), the final date for the
filing of proofs of claim in the winding-up of the Company shall be the date
fixed by the liquidator or otherwise in accordance with the relevant provisions
of applicable law as being the latest practicable date as at which liabilities
of the Company may be ascertained for such winding-up prior to payment by the
liquidator or otherwise in respect thereto.

               (d) The obligations contained in Subsections (b) and (c) of this
Section 1.15 shall constitute separate and independent obligations of the
Company from its other obligations under the Securities and this Indenture,
shall give rise to separate and independent causes of action against the
Company, shall apply irrespective of any waiver or extension granted by any
Holders or the Trustees or any of them from time to time and shall continue in
full force and effect notwithstanding any judgment or order or the filing of any
proof of claim in the winding-up of the Company for a liquidated sum in respect
of amounts due hereunder (other than under subsection (c) above) or under any
such judgment or order. Any such deficiency as aforesaid shall be deemed to
constitute a loss suffered by the Holders or the Trustee, as the case may be,
and no proof or evidence of any actual loss shall be required by the Company or
the liquidator or otherwise or any of them which shall be liable for such
deficiency. In the case of Subsection (c) above, the amount of such deficiency
shall not be deemed to be reduced by any variation in rates of exchange
occurring between the said final date and the date of any liquidating
distribution.

               (e) The term "rate(s) of exchange" shall mean the rate of
exchange quoted by The Bank of New York as its central foreign exchange desk in
its head office in New York, New York at 12:00 noon (New York City time) for the
purchases of U.S. Dollars with the judgment currency other than U.S. Dollars
referred to in subsections (a) and (c) above and includes any premiums and costs
of exchange payable.

               (f) The Trustee shall have no duty or liability with respect to
monitoring or enforcing this Section 1.15 and shall have no liability to the
Holders due to fluctuations in currency rates.

                                   ARTICLE II
                                FORMS OF SECURITY

               SECTION 2.01 Forms Generally.

amount at maturity may from time to time be increased or decreased to such other
stated amounts at maturity, as may be set forth in the records of the Trustee

to pay interest thereon at a rate of 8.875% per annum in cash semi-annually to
the Holder of record at the close of business on January 1 and July 1, as the
case may be, (the "Regular Record Date") immediately preceding the applicable

the extent permitted by law, overdue interest at a rate of 8.875% plus 1% per
annum; [IF THE SECURITY IS AN ORIGINAL SECURITY, THEN INSERT -- provided that if
(i) the Company has not filed a registration statement (the "Exchange
Registration Statement") under the Securities Act of 1933, as amended (the

Securities) is registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest to be fixed by the Trustee, notice of
which states the Special Record Date, the payment date (which shall be not less

than 10 days prior to such Special Record Date, or be paid at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in said Indenture.
Interest on this Security shall be computed on the basis set forth in the

<PAGE>   32

               SECTION 2.03 Form of Reverse of Security.

               This Security is one of a duly authorized issue of Securities of
the Company designated as its 8.875% Senior Notes due July 15, 2011 (herein
called the "Securities"), issued and to be issued under an indenture dated as of
June 22, 2001 (herein called the "Indenture"), between the Company and U.S.
Trust Company of Texas, N.A., as Trustee (herein called the "Trustee", which
term includes any successor trustee under the Indenture), to which Indenture and
all indentures supplemental thereto reference is hereby made for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee and the Holders of the Securities and of the terms
upon which the Securities are, and are to be, authenticated and delivered.

               As provided for in the Indenture, the Company may, subject to
certain limitations, from time to time, without notice or other consent of the
Holders, create and issue Additional Securities ranking pari passu with the
Securities issued the date hereof so that such Additional Securities shall be
consolidated and form a single series with the Securities initially issued by
the Company and shall have the same terms as to status, redemption or otherwise
as Securities originally issued. Any Additional Securities shall be issued with
the benefit of any indenture supplemental to the Indenture.

               At the Company's option, the Company may redeem the Securities in
whole or in part at any time at a redemption price equal to the greater of (i)
100% of the principal amount of the Securities to be redeemed and (ii) the sum
of the present values of the remaining scheduled payments of principal and
interest on the Securities to be redeemed (excluding the portion of any such
interest accrued to the Redemption Date) discounted to the Redemption Date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Treasury Yield, plus 50 basis points, plus, in each case, accrued and
unpaid interest to the Redemption Date.

               The Securities shall be subject to redemption, at the option of
the Company, as a whole but not in part, at any time upon not fewer than 30 nor
more than 60 days' notice mailed to each Holder of Securities at the addresses
appearing in the Security Register at a redemption price equal to 100% of the
principal amount of the Securities plus accrued interest to but excluding the
Redemption Date if the Company has become or would become obligated to pay on
the next date on which any amount would be payable under or with respect to the
Securities, any Additional Amounts as a result of any change or amendment to the
laws (including any regulations promulgated thereunder) of any Taxing
Jurisdiction, or any change in or amendment to any official position regarding
the application or interpretation of such laws or regulations, which change or
amendment is announced or becomes effective on or after June 22, 2001.

               If less than all of the Securities are to be redeemed at any
time, the Trustee shall select the Securities to be redeemed by such method as
the Trustee shall deem fair and appropriate in the aggregate principal amount
specified by the Company. The Trustee may select for redemption Securities and
portions of Securities in amounts of U.S.$1,000 or whole multiples of
U.S.$1,000.

               The Securities do not have the benefit of any sinking fund
obligations.

               In the event of redemption or purchase pursuant to an Offer to
Purchase of this Security in part only, a new Security or Securities for the
unredeemed or unpurchased portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof.

                                       25
<PAGE>   33

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

               The Indenture provides that, subject to certain conditions, if a
Change of Control Triggering Event occurs, the Company shall be required to make
an Offer to Purchase for all or a specified portion of the Securities.

               The Indenture contains provisions for defeasance at any time of
(i) the entire indebtedness of this Security or (ii) certain restrictive
covenants and Events of Default with respect to this Security, in each case upon
compliance with certain conditions set forth therein.

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

               The Holder of this Security (and any Person that has a beneficial
interest in this Security) is entitled to the benefits of the Exchange and
Registration Rights Agreement. The Exchange and Registration Rights Agreement
provides that the rate of interest borne by the Securities is subject to
increase for specified periods if the Company does not comply with certain of
its obligations thereunder. Such provisions of the Exchange and Registration
Rights Agreement are hereby incorporated by reference and made a part hereof,
and the Company shall promptly notify the Trustee of the occurrence of any
Registration Default under the Exchange and Registration Rights Agreement.

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

               As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in the Borough of Manhattan, the City of New
York, duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Security Registrar duly executed by,
the Holder hereof or his attorney duly authorized in writing, and thereupon one
or more new Securities, of authorized denominations and for the same aggregate
stated amount at maturity, will be issued to the designated transferee or
transferees.

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

                                       26
<PAGE>   34

               No service charge shall be made for any such registration of

things, that all conditions hereunder precedent to the authentication and
delivery of such Exchange Securities have been complied with and shall be
accompanied by an Opinion of Counsel stating in substance that such Exchange
Securities have been duly executed and, when such Securities have been duly
authenticated and delivered by the Trustee, will be duly issued and delivered
and will constitute valid and legally binding obligations of the Company,
enforceable in accordance with their terms, subject to any applicable
bankruptcy, insolvency (including, without limitation, all laws relating to
fraudulent transfers), reorganization, moratorium or similar laws affecting
creditors' rights generally and subject to the effect of general principles of
equity, including, without limitation, concepts of materiality, reasonableness,
good faith and fair dealing (regardless of whether enforcement is considered in
a proceeding in equity or at law).

               (f) No Security shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for
herein executed by the Trustee by manual signature, and such certificate upon
any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder.

               (g) In case the Company, pursuant to Article Eight, shall be
consolidated or merged with or into any other Person or shall convey, transfer,
lease or otherwise dispose of substantially all of its properties and assets to

surviving such merger, or into which the Company shall have been merged, 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 Eight, any of the Securities
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 Securities executed in the name of
the successor Person with such changes in phraseology and form as may be
appropriate, but otherwise in substance of like tenor as the Securities
surrendered for such exchange and of like principal amount; and the Trustee upon
Company Order of the successor Person, shall authenticate and deliver
replacement Securities as specified in such request for the purpose of such
exchange. If replacement Securities 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 Securities,
such successor Person, at the option of any Holder but without expense to such
Holder, shall provide for the exchange of all Securities at the time outstanding
held by such Holder for Securities authenticated and delivered in such new name.

               SECTION 3.04 Temporary Securities.

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

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

Generally.

                    (1) The Company shall cause to be kept at the Corporate
               Trust Office of the Trustee a register (the register maintained
               in such office and in any other office or agency designated
               pursuant to Section 10.02 being herein sometimes collectively
               referred to as the "Security Register") in which, subject to such
               reasonable regulations as it may prescribe, the Company shall
               provide for the registration of Securities and of transfers and
               exchanges of Securities. The Trustee is hereby appointed
               "Security Registrar" for the purpose of registering Securities
               and transfers and exchanges of Securities as herein provided.
               Such Security Register shall distinguish between Original
               Securities and Exchange Securities.

                    (2) Upon surrender for registration of transfer of any
               Security at an office or agency of the Company designated
               pursuant to Section 10.02 for such purpose, the

               one or more new Securities of any authorized denominations and of
               a like aggregate stated amount at Maturity bearing such
               restrictive legends as may be required by this Indenture.

                    (3) At the option of the Holder, and subject to the other
               provisions of this Section 3.05, Securities may be exchanged for
               other Securities of any authorized denominations and of a like
               aggregate stated amount at Maturity, upon surrender of the
               Securities to be exchanged at such office or agency. Whenever any
               Securities are so surrendered for exchange, and subject to the
               other provisions of this Section 3.05, the Company shall execute,
               and the Trustee shall authenticate and deliver, the Securities
               which the Holder making the exchange is entitled to receive.

                    (4) All Securities issued upon any registration of transfer
               or exchange of Securities shall be the valid obligations of the
               Company, evidencing the same debt, and (except for the
               differences between Original Securities and Exchange Securities
               provided for in this Indenture) entitled to the same benefits
               under this Indenture, as the Securities surrendered upon such
               registration of transfer or exchange.

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

                    (6) No service charge shall be made for any registration of
               transfer or exchange of Securities, but the Company may require
               payment of a sum sufficient to cover any tax or other
               governmental charge that may be imposed in connection with any
               registration of transfer or exchange of Securities, other than
               exchanges pursuant to Section 3.04, 9.06 or 11.08 or in
               accordance with any Offer to Purchase pursuant to Section 10.09
               not involving any transfer.

                    (7) The Company shall not be required (i) to issue, register
               the transfer of or exchange any Security during a period
               beginning at the opening of business 15 days before the day of

               redemption under Section 11.04 and ending at the close of
               business on the day of such mailing, or (ii) to register the
               transfer of or exchange any Security so selected for redemption
               in whole or in part, except the unredeemed portion of any
               Security being redeemed in part.

               (b) Certain Transfers and Exchanges.

                    (1) Notwithstanding any other provisions of this Indenture
               or the Securities, transfers and exchanges of Securities and
               beneficial interests in a Global Security of the kinds specified
               in this Subsection 3.05(b) shall be made only in accordance with
               this Subsection 3.05(b). Transfers and exchanges subject to this
               Subsection 3.05(b) shall also be subject to the other provisions
               of this Indenture that are not inconsistent with this Subsection
               3.05(b).

               an effective Registration Statement, or (B) an Original Security
               is exchanged for an Exchange Security in connection with an
               effective registration statement, pursuant to the Exchange and
               Registration Rights Agreement, the following provisions shall

                    Security to be so transferred, (B) a written order given in
                    accordance with the Applicable Procedures containing
                    information regarding the account of the Agent Member (and
                    the Euroclear or Clearstream account, as the case may be) to
                    be credited with, and the account of the Agent Member to be
                    debited for, such beneficial interest and (C) a Regulation S
                    Certificate, substantially in the form of Annex A hereto
                    given by the holder of such beneficial interest, the
                    principal amount of the Restricted Global Security shall be
                    reduced, and the principal amount of the Regulation S Global
                    Security shall be increased, by the principal amount of the
                    beneficial interest in the Restricted Global Security to be
                    so transferred, in each case by means of an appropriate
                    adjustment on the records of the Trustee, as Security
                    Registrar, and the Trustee, as Security Registrar, shall
                    instruct the United States Depositary or its authorized
                    representative to make a corresponding adjustment to its
                    records and to credit or cause to be credited to the account
                    of the Person specified in such instructions (which shall be
                    the Agent Member for Euroclear or Clearstream or both, as
                    the case may be) a beneficial interest in the Regulation S
                    Global Security having a principal amount equal to the
                    amount so transferred.

                    Security. If the holder of a beneficial interest in the
                    Regulation S Global Security wishes at any time to transfer
                    such interest to a Person who is required or permitted to

                    in the Restricted Global Security, such transfer may be
                    effected, subject to the Applicable Procedures, only in

                    interest in the Restricted Global Security in a principal
                    amount equal to that of the beneficial interest in the
                    Regulation S Global Security to be so transferred, (B) a
                    written order given in accordance with the Applicable

                    holder of such beneficial interest, the principal amount of
                    the Regulation S Global Security shall be reduced, and the
                    principal amount of the Restricted Global Security shall be
                    increased, by the principal amount of the beneficial
                    interest in the Regulation S Global Security to be so
                    transferred, in each case by means of an appropriate
                    adjustment on the records of the Trustee, as Security
                    Registrar, and the Trustee, as Security Registrar, shall
                    instruct the United States Depositary or its authorized
                    representative to make a corresponding adjustment to its
                    records and to credit or cause to be credited to the account
                    of the Person specified in such instructions a beneficial
                    interest in the Restricted Global Security having a
                    principal amount equal to the amount so transferred.

                         (iii) Non-Global Security for Non-Global Security. A
                    Security that bears a Securities Act Legend that it is not a
                    Global Security may be transferred, in whole or in part, to
                    a Person who takes delivery in the form of another Security
                    that is not a Global Security as provided in Section
                    3.05(a), provided that, if the Security to be transferred in
                    whole or in part is a Restricted Security, or is a
                    Regulation S Security, then the Trustee shall have received
                    (A) a Restricted Securities Certificate substantially in the
                    form attached hereto as Annex B and duly executed by the
                    transferor holder or his attorney duly authorized in
                    writing, in which case the transferee Holder shall take
                    delivery in the form of a Restricted Security, or (B) a
                    Regulation S Certificate, substantially in the form attached
                    hereto as Annex A and duly executed by the transferee holder
                    of his attorney duly authorized in writing, in which case
                    the transferee holder shall take delivery in the form of a
                    Regulation S Security (subject in each case to Section
                    3.05(c)).

                         (iv) Interests in Regulation S Global Security to be
                    Held Through Euroclear or Clearstream. Interests in the
                    Regulation S Global Security may be held only through Agent
                    Members acting for and on behalf of Euroclear and
                    Clearstream, provided that this clause (iv) shall not
                    prohibit any transfer in accordance with Subsection
                    3.05(b)(2)(ii) hereof.

               (c) Securities Act Legends. Restricted Securities and their
Successor Securities shall bear a Restricted Securities Legend and Regulation S
Securities and their Successor Securities shall bear a Regulation S Legend,
subject to the following:

               (1) subject to the following clauses of this Section 3.05(c), a
          Security or any portion thereof which is exchanged, upon transfer or
          otherwise, for a Global Security or any portion thereof shall bear the
          Securities Act Legend borne by such Global Security while represented
          thereby;

               (2) subject to the following clauses of this Section 3.05(c), a
          new Security which is not a Global Security and is issued in exchange
          for another Security (including a Global Security) or any portion
          thereof, upon transfer or otherwise, shall bear the Securities Act
          legend borne by such other Security, provided that, if such new
          Security is required pursuant to Section 3.05(b)(2)(iii) to be issued
          in the form of a Restricted Security, it shall bear a Restricted
          Securities Legend and, if such new Security is so

                                       34
<PAGE>   42

          required to be issued in the form of a Regulation S Security, it shall
          bear a Regulation S Legend;

               (3) Securities that are sold or otherwise disposed of pursuant to
          an effective registration statement under the Securities Act
          (including any shelf registration contemplated by the Exchange and
          Registration Rights Agreement) shall not bear a Securities Act Legend;

               (4) notwithstanding the foregoing provisions of this Section
          3.05(c), a Successor Security of a Security that does not bear a
          particular form of Securities Act Legend shall not bear such form of
          legend unless the Company has reasonable cause to believe that such
          Successor Security is a "restricted security" within the meaning of
          Rule 144, in which case the Trustee, at the direction of the Company,
          shall authenticate and deliver a new Security bearing a Restricted
          Securities Legend in exchange for such Successor Security as provided
          in this Article Three;

               (5) the Securities may not be reoffered, resold, pledged or
          otherwise transferred except (A)(i) to a person reasonably believed by
          the seller to be a qualified institutional buyer in a transaction
          meeting the requirements of Rule 144A, (ii) in an offshore transaction
          complying with Rule 903 or Rule 904 of Regulation S, (iii) pursuant to
          an exemption from registration under the Securities Act provided by
          Rule 144 thereunder (if available), (iv) to an institutional
          accredited investor in a transaction exempt from the registration
          requirements of the Securities Act or (v) pursuant to an effective
          registration statement under the Securities Act, and (B) in each case,
          in accordance with applicable securities laws of the United States.
          The Trustee shall have no duty or liability with respect to any
          Holder's or beneficial owner's compliance with Rule 144A or Regulation
          S, as applicable; and

               (6) Exchange Securities and their respective Successor Securities
          shall not bear a Securities Act Legend.

               (d) The provisions of clauses (1), (2), (3), (4) and (5) of this
Subsection (d) shall apply only to Global Securities:

               (1) Each Global Security authenticated under this Indenture shall
          be registered in the name of the United States Depositary or a nominee
          thereof and delivered to the United States Depositary or a nominee
          thereof or custodian therefor, and each such Global Security shall
          constitute a single Security for all purposes of this Indenture.

               (2) Notwithstanding any other provision in this Indenture or the
          Securities, no Global Security may be exchanged in whole or in part
          for Securities registered, and no transfer of a Global Security in
          whole or in part may be registered, in the name of any Person other
          than the United States Depositary or a nominee thereof unless (A) the
          United States Depositary (i) has notified the Company that it is
          unwilling or unable to continue as United States Depositary for such
          Global Security or (ii) has ceased to be a clearing agency registered
          under the Exchange Act, and in either case the Company thereupon fails
          to appoint a successor depositary within 120 days of such notice, (B)
          the Company, at its option, executes and delivers to the Trustee a
          Company Order that such Global Security shall be exchanged in whole
          for Securities that are not Global Securities,

                                       35
<PAGE>   43

          or (C) there shall have occurred and be continuing an Event of Default
          with respect to such Global Security.

               (3) Securities issued in exchange for a Global Security or any
          portion thereof pursuant to clause (2) of this Subsection (d) shall be
          issued in definitive, fully registered form, without interest coupons,
          shall have an aggregate principal amount equal to that of such Global
          Security or portion thereof to be so exchanged, shall be registered in
          such names and be in such authorized denominations as the United
          States Depositary shall designate and shall bear any legends required
          hereunder. Any Global Security to be exchanged in whole shall be
          surrendered by the United States Depositary to the Trustee, as
          Security Registrar. With regard to any Global Security to be exchanged
          in part, either such Global Security shall be so surrendered for
          exchange or, if the Trustee is acting as custodian for the United
          States Depositary or its nominee with respect to such Global Security,
          the principal amount thereof shall be reduced, by an amount equal to
          the portion thereof to be so exchanged, by means of an appropriate
          adjustment made on the records of the Trustee and the United States
          Depositary. Upon any such surrender or adjustment, the Trustee shall
          authenticate and deliver the Security issuable on such exchange to or
          upon the order of the United States Depositary or an authorized
          representative thereof.

               (4) In the event of the occurrence of any of the events specified
          in clause (2) of this Subsection (d), the Company will promptly make
          available to the Trustee a reasonable supply of certificated
          Securities in definitive, fully registered form, without interest
          coupons.

               (5) Neither any Agent Members nor any other Persons on whose
          behalf Agent Members may act (including Euroclear and Clearstream and
          account holders and participants therein) shall have any rights under
          this Indenture with respect to any Global Security, or under any
          Global Security, and the United States Depositary or such nominee, as
          the case may be, may be treated by the Company, the Trustee and any
          agent of the Company or the Trustee as the absolute owner and Holder
          of such Global Security for all purposes whatsoever. Notwithstanding
          the foregoing, nothing herein shall prevent the Company, the Trustee
          or any agent of the Company or the Trustee from giving effect to any
          written certification, proxy or other authorization furnished by the
          United States Depositary or such nominee, as the case may be, or
          impair, as between the United States Depositary, its Agent Members and
          any other person on whose behalf an Agent Member may act, the
          operation of customary practices of such Persons governing the
          exercise of the rights of a Holder of any Security.

               SECTION 3.06 Mutilated, Destroyed, Lost and Stolen Securities.

               (a) If any mutilated Security is surrendered to the Trustee, the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and stated amount at Maturity and bearing
a number not contemporaneously outstanding.

               (b) (1) If there shall be delivered to the Company and the
Trustee (A) evidence to their satisfaction of the destruction, loss or theft of
any Security and (B) such security or indemnity as may be required by them to
save each of them and any agent of either of them harmless, then, in the absence
of notice to the Company or the Trustee that such Security has been acquired by
a bona fide purchaser, the Company shall execute and upon its request the
Trustee shall authenticate and deliver, in

                                       36
<PAGE>   44

lieu of any such destroyed, lost or stolen Security, a new Security of like
tenor and stated amount at Maturity and bearing a number not contemporaneously
outstanding.

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

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

               (d) Every new Security issued pursuant to this Section in lieu of
any mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder.

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

               SECTION 3.07 Payment of Interest; Interest Rights Preserved.

               (a) Interest on any Security which is payable, and is punctually
paid or duly provided for, on any Interest Payment Date shall be paid to the
Person in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest.

               (b) Any interest on any Security which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) of this Subsection (b):

                    (1) The Company may elect to make payment of any Defaulted
               Interest to the Persons in whose names the Securities (or their
               respective Predecessor Securities) are registered at the close of
               business on a Special Record Date for the payment of such
               Defaulted Interest, which shall be fixed in the following manner.
               The Company shall notify the Trustee in writing of the amount of
               Defaulted Interest proposed to be paid on each Security and the
               date of the proposed payment, and at the same time the Company
               shall deposit with the Trustee an amount of money equal to the
               aggregate amount proposed to be paid in respect of such Defaulted
               Interest or shall make arrangements satisfactory to the Trustee
               for such deposit prior to the date of the proposed payment, such
               money when deposited to be held in trust for the benefit of the
               Persons entitled to such Defaulted Interest as in this clause
               provided. Thereupon the Trustee shall fix a Special Record Date
               for the payment of such Defaulted Interest which shall be not
               more than 15 days and not less than 10 days prior to the date of
               the proposed payment and not less than 10 days after the receipt
               by the Trustee of the notice of the proposed payment. The Trustee
               shall promptly notify the Company of such Special Record Date
               and, in the name and at the expense of the Company, shall cause
               notice of the proposed payment of such Defaulted Interest and the
               Special Record Date therefor to be mailed, first-class postage
               prepaid, to each Holder at his address as it appears in the
               Security Register, not less than 10 days prior to such Special
               Record Date. Notice of the proposed payment of

                                       37
<PAGE>   45

               such Defaulted Interest and the Special Record Date therefor
               having been so mailed, such Defaulted Interest shall be paid to
               the Persons in whose names the Securities (or their respective
               Predecessor Securities) are registered at the close of business
               on such Special Record Date and shall no longer be payable
               pursuant to clause (2) of this Subsection (b).

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

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

               SECTION 3.08 Persons Deemed Owners.

               Prior to due presentment of a Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Security is registered on the Securities
Register as the owner of such Security for the purpose of receiving payment of
stated amount at Maturity of (and premium, if any) and (subject to Section 3.07)
interest on such Security and for all other purposes whatsoever, whether or not
such Security be overdue, and neither the Company, the Trustee nor any agent of
the Company or the Trustee shall be affected by notice to the contrary.

               SECTION 3.09 Cancellation.

               All Securities surrendered for payment, redemption, registration
of transfer or exchange or for credit against any Offer to Purchase pursuant to
Section 10.09 shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee and shall be promptly cancelled by it. The Company
shall deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Securities so delivered shall be promptly cancelled
by the Trustee. No Securities shall be authenticated in lieu of or in exchange
for any Securities cancelled as provided in this Section, except as expressly
permitted by this Indenture. All cancelled Securities held by the Trustee shall
be disposed of by the Trustee in accordance with its customary procedures and
certification of their disposal delivered to the Company unless by Company Order
the Company shall direct that cancelled Securities be returned to it.

               SECTION 3.10 Computation of Interest.

               Interest on the Securities shall be computed on the basis of a
360-day year of twelve 30-day months.

               SECTION 3.11 CUSIP Numbers.

               The Company in issuing the Securities may use "CUSIP" numbers
and, if so, the Trustee shall use "CUSIP" numbers in notices of redemption and
other notices to Holders as a convenience to

                                       38
<PAGE>   46

Holders; provided, however, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption or other notice
and that reliance may be placed only on the other identification numbers printed
on the Securities, and any such redemption or notice shall not be affected by
any defect in or such omission of such numbers.

                                   ARTICLE IV
                           SATISFACTION AND DISCHARGE

               SECTION 4.01 Satisfaction and Discharge of Indenture.

               (a) This Indenture shall cease to be of further effect (except as
to any surviving rights of registration of transfer or exchange of Securities
herein expressly provided for), and the Trustee, upon a Company Order and at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture (including, but not limited to,
Article Twelve), when

                    (1) either

                         (i) all Securities theretofore authenticated and
                    delivered (other than (i) Securities which have been
                    destroyed, lost or stolen and which have been replaced or
                    paid as provided in Section 3.06 and (ii) Securities for
                    whose payment money has theretofore been deposited in trust
                    or segregated and held in trust by the Company and
                    thereafter repaid to the Company or discharged from such
                    trust, as provided in Section 10.03) have been delivered to
                    the Trustee for cancellation; or

                         (ii) all such Securities not theretofore delivered to
                    the Trustee for cancellation

                             (a) have become due and payable, or

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

                             (c) are to be called for redemption within one year
                         under arrangements satisfactory to the Trustee for the
                         giving of notice of redemption by the Trustee in the
                         name, and at the expense, of the Company,

                         and the Company, in the case of subclause (a), (b) or
                         (c) of this Subsection (a)(1)(ii), has deposited or
                         caused to be deposited with the Trustee as trust funds
                         in trust for the purpose an amount sufficient to pay
                         and discharge the entire indebtedness on such
                         Securities not theretofore delivered to the Trustee for
                         cancellation, for stated amount at Maturity (and
                         premium, if any) and interest to the date of such
                         deposit (in the case of Securities which have become
                         due and payable) or to the Stated Maturity or
                         Redemption Date, as the case may be;

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

Indenture pursuant to this Article Four, the obligations of the Company to the
Trustee under Section 6.07 and, if money shall have been deposited with the
Trustee pursuant to subclause (ii) of Subsection (a)(1) of this Section, the
obligations of the Trustee under Section 4.02 and Section 10.03(e) shall
survive.

               Subject to the provisions of the last paragraph of Section 10.03,
all money deposited with the Trustee pursuant to Section 4.01 shall be held in

this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the stated amount at Maturity
(and premium, if any) and interest for whose payment such money has been
deposited with the Trustee.

                                    REMEDIES

               SECTION 5.01 Events of Default.

               (a) "Event of Default", wherever used herein, means any one of
the following events (whatever the reason for such Event of Default and whether
it be voluntary or involuntary or be effected by operation of law or pursuant to
any judgment, decree or order of any court or any order, rule or regulation of
any administrative or governmental body):

                    (1) default in the payment of the principal of (or premium,
               if any, on) any Security at its Maturity; or

                    (2) default in the payment of any interest upon any Security
               when it becomes due and payable, and continuance of such default
               for a period of 30 days; or

                    (3) default in the payment of principal and interest on
               Securities required to be purchased upon the occurrence of a
               Change of Control Triggering Event when due and payable; or

                    (4) default in the performance, or breach, of any covenant
               or agreement of the Company in this Indenture (other than a
               covenant or agreement a default in whose performance or whose
               breach is elsewhere in this Section specifically dealt with), and
               continuance of such default or breach for a period of 30
               consecutive days after there has been given, by registered or
               certified mail, to the Company by the Trustee or to the Company
               and the Trustee by the Holders of at least 25% in aggregate
               principal amount of the Outstanding Securities a written notice
               specifying such default or breach and requiring it to be remedied
               and stating that such notice is a "Notice of Default"; or

                    (5) a default or defaults with respect to any issue or
               issues of Debt of the Company or any Subsidiary having an
               outstanding aggregate principal amount of $10 million or more

               issues of

                                       40
<PAGE>   48

               all such Persons, whether such Debt now exists or shall hereafter
               be created, which default or defaults shall constitute a failure
               to pay all or any portion of the principal of such Debt when due
               and payable or shall have resulted in such Debt becoming or being
               declared due and payable prior to the date on which it would
               otherwise have become due and payable and such Debt has not been
               discharged in full or such acceleration has not been rescinded or
               annulled (by cure, waiver or otherwise) within 30 days of such
               acceleration; provided, however, that any secured Debt in excess
               of the limits set forth above shall be deemed to have been
               declared due and payable if the lender in respect thereof takes
               any action to enforce a security interest against, or an
               assignment of, or to collect on, seize, dispose of or apply any
               assets of the Company or its Subsidiaries (including lock-box and
               other similar arrangements) securing such Debt, or to set off
               against any bank account of the Company or its Subsidiaries in
               excess of $10 million; or

                    (6) any final judgment or order (not covered by insurance)
               for the payment of money in excess of $10 million individually or
               $20 million in the aggregate for all such final judgments or
               orders against all such Persons (treating any deductibles,
               self-insurance or retention as not so covered) shall be rendered
               against the Company or any Subsidiary and shall not be paid or
               discharged, and there shall be any period of 60 consecutive days
               following entry of the final judgment or order in excess of $10
               million individually or that causes the aggregate amount for all
               such final judgments or orders outstanding and not paid or
               discharged against all such Persons to exceed $20 million during
               which a stay of enforcement of such final judgment or order, by
               reason of a pending appeal or otherwise, shall not be in effect;
               or

                    (7) the Company or any Subsidiary shall generally not pay
               its debts as such debts become due, or shall admit in writing its
               inability to pay its debts generally, or shall make a general
               assignment for the benefit of creditors; or any proceeding shall
               be instituted by or against the Company or any Subsidiary seeking
               to adjudicate it a bankrupt or insolvent, or seeking liquidation,
               winding up, reorganization, arrangement, adjustment, protection,
               relief or composition of it or its debts under any law relating
               to bankruptcy, insolvency or reorganization or relief of debtors,
               or seeking the entry of an order for relief or the appointment of
               a receiver, trustee, custodian or other similar official for it
               or for any substantial part of its property and, in the case of
               any such proceeding instituted against it (but not instituted by
               it), either such proceeding shall remain undismissed or unstayed
               for a period of 60 days, or any of the actions sought in such
               proceeding (including, without limitation, the entry of an order
               for relief against, or the appointment of a receiver, trustee,
               custodian or other similar official for, it or for any
               substantial part of its property) shall occur; or the Company or
               any Subsidiary shall take any corporate action to authorize any
               of the actions set forth above in this Subsection (7);

                    (8) the Company and/or one or more Subsidiaries fails to
               make (A) at the final (but not any interim) fixed maturity of any
               issue of Debt a principal payment of $10 million or more or (B)
               at the final (but not any interim) fixed maturity of more than
               one issue of such Debt principal payments aggregating $20 million
               or more and, in the case of clause (A), such defaulted payment
               shall not have been made, waived or extended within 30 days of
               the payment default and, in the case of clause (B), all such
               defaulted payments shall not have been made, waived or extended
               within 30 days of the payment default that causes the amount
               described in clause (B) to exceed $20 million.

               SECTION 5.02 Acceleration of Maturity; Rescission and Annulment.

               (a) If an Event of Default (other than an Event of Default
specified in Subsection 5.01(a)(7)) shall occur and be continuing, then and in
every such case the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Outstanding Securities may, and the Trustee at the
request of such Holders shall, declare the entire unpaid principal of, premium,
if any, and accrued interest on the Securities to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal of, premium, if any,
and accrued interest on the Securities shall become immediately due and payable.
If an Event of Default specified in Subsection 5.01(a)(4) or (8) occurs, such
declaration of acceleration shall be automatically rescinded and annulled if the
event triggering such Event of Default pursuant to Subsection 5.01(a)(4) or (8)
shall be remedied or cured by the Company and/or the relevant Subsidiaries or
waived by the Holders of the Relevant Debt within 60 days after the declaration
of acceleration with respect thereto.

               (b) If an Event of Default specified in Subsection 5.01(a)(7)
above occurs, all unpaid principal of, premium, if any, and accrued interest on
the Securities then outstanding shall ipso facto become and be immediately due
and payable without any declaration or other act on the part of the Trustee or
any Holder. The Holders of at least a majority in principal amount of the
outstanding Securities by written notice to the Company and to the Trustee, may
waive all past defaults and rescind and annul a declaration of acceleration and
its consequences if:

                    (1) the Company has paid or deposited with the Trustee a sum
               sufficient to pay (A) all sums paid or advanced by the Trustee
               under this Indenture and the reasonable compensation, expenses,
               disbursements and advances of the Trustee, its agents and
               counsel, (B) all overdue interest on all Securities, (C) the
               principal of (and premium, if any, on), any Securities that have
               become due otherwise than by such declaration or occurrence of
               acceleration and interest thereon at the rate prescribed therefor
               by such Securities, and (D) to the extent that payment of such
               interest is lawful, interest upon overdue interest at the rate
               prescribed therefor by such Securities,

                    (2) all existing Events of Default, other than the
               non-payment of the principal of the Securities that have become
               due solely by such declaration of acceleration, have been cured
               or waived, and

                    (3) the rescission would not conflict with any judgment or
               decree of a court of competent jurisdiction.

               SECTION 5.03 Collection of Indebtedness and Suits for Enforcement
by Trustee.

               (a) The Company covenants that if

                    (1) default is made in the payment of any interest on any
               Security when such interest becomes due and payable and such
               default continues for a period of 30 days, or

                    (2) default is made in the payment of the stated amount at
               Maturity of (or premium, if any, on) any Security at the Maturity
               thereof or, with respect to any Security required to have been
               purchased pursuant to an Offer to Purchase made by the Company,
               at the Purchase Date thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities, including, as applicable, the stated amount at

                                       42
<PAGE>   50

Maturity (and premium, if any) and interest, and, to the extent that payment of
such interest shall be legally enforceable, interest on any overdue stated
amount at Maturity (and premium, if any) and on any overdue interest, at the
rate provided by the Securities, and, in addition thereto, such further amount
as shall be sufficient to cover the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel.

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

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

               SECTION 5.04 Trustee May File Proofs of Claim.

               (a) In case of any judicial proceeding relative to the Company
(or any other obligor upon the Securities), its property or its creditors, the
Trustee shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 6.07.

               (b) No provision of this Indenture shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

               SECTION 5.05 Trustee May Enforce Claims Without Possession of
Securities.

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

<PAGE>   51

               SECTION 5.06 Application of Money Collected.

               Subject to Article Twelve, any money collected by the Trustee
pursuant to this Article shall be applied in the following order, at the date or
dates fixed by the Trustee and, in case of the distribution of such money on
account of stated amount at Maturity (or premium, if any) or interest, upon
presentation of the Securities and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

               FIRST: To the payment of all amounts due the Trustee under
               Section 6.07; and

               SECOND: To the payment of the amounts then due and unpaid for
               stated amount at Maturity of (and premium, if any) and interest
               on the Securities in respect of which or for the benefit of which
               such money has been collected, ratably, without preference or
               priority of any kind, according to the amounts due and payable on
               such Securities for stated amount at Maturity (and premium, if
               any) and interest, respectively.

               SECTION 5.07 Limitation on Suits.

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

               (a) such Holder has previously given written notice to the
Trustee of a continuing Event of Default;

               (b) the Holders of not less than 25% in aggregate stated amount
at Maturity of the Outstanding Securities shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default in its own
name as Trustee hereunder;

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

               (d) the Trustee for 60 days after its receipt of such notice,
request and offer 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
aggregate stated amount at Maturity of the Outstanding Securities;

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

               SECTION 5.08 Unconditional Right of Holders to Receive Stated
Amount at Maturity, Premium and Interest.

               Notwithstanding any other provision in this Indenture, the Holder
of any Security shall have the right, which is absolute and unconditional, to
receive payment of the stated amount at Maturity

                                       44
<PAGE>   52

of (and premium, if any) and (subject to Section 3.07) interest on such Security
on the respective Stated Maturities expressed in such Security (or, in the case
of redemption, on the Redemption Date or in the case of an Offer to Purchase
made by the Company and required to be accepted as to such Security, on the
Purchase Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired or affected 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, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

               SECTION 5.10 Rights and Remedies Cumulative.

               Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last paragraph
of Section 3.06, 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
Security to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event
of Default or an acquiescence therein. Every right and remedy given by this
Article or by law to the Trustee or to the Holders may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or by the Holders,
as the case may be.

               SECTION 5.12 Control by Holders.

               The Holders of a majority in aggregate principal amount of the
Outstanding Securities 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 and shall not expose the Trustee to personal liability,
and (b) 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.

               (a) The Holders of not less than a majority in aggregate
principal amount of the Outstanding Securities may, on behalf of the Holders of
all the Securities, waive any past default hereunder and its consequences,
except a default

                                       45
<PAGE>   53

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

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

               (b) Upon any such waiver described in Subsection (a) of this
Section, 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; provided that no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

               SECTION 5.14 Undertaking for Costs.

               In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided, that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company or the Trustee.

               SECTION 5.15 Waiver of Stay or Extension Laws.

               The Company covenants (to the extent that it may lawfully do so)
that it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage or 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 No Personal Liability of Incorporators,
Shareholders, Officers, Directors or Employees.

               No recourse for the payment of the principal of, premium, if any,

Affiliate or controlling person of the Company or of any successor Person
thereof.

               SECTION 6.01 Certain Duties and Responsibilities.

               The duties and responsibilities of the Trustee shall be as
provided by the Trust Indenture Act. Notwithstanding the foregoing, no provision
of this Indenture shall require the Trustee to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not

                                       46
<PAGE>   54

reasonably assured to it. Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section.

               SECTION 6.02 Notice of Defaults.

               The Trustee shall give the Holders notice of any default

however, that in the case of any default of the character specified in Section
5.01(a)(5), no such notice to Holders shall be given until at least 30 days
after the occurrence thereof. For the purpose of this Section, the term
"default" means any event which is, or after notice or lapse of time or both
would become, an Event of Default.

               SECTION 6.03 Certain Rights of Trustee.

               (a) Except during the continuance of an Event of Default, the
Trustee undertakes to perform such functions and duties and only such functions
and duties as are specifically set forth in this Indenture, and no implied
duties or obligations shall be read into this Indenture against the Trustee.
During the continuance of an Event of Default, the Trustee shall exercise the
same degree of care and skill as a prudent person would exercise under the
circumstances in the conduct of such person's own affairs. No provision of this
Indenture shall be construed to relieve the Trustee from its duties, except to
the extent permitted by the Trust Indenture Act. Subject to the provisions of
Section 6.01, whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.

               (b)

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

                    (2) 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;

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

                    (4) the Trustee may consult with counsel and the oral or
               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;

                    (5) 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
               reasonable security or indemnity against the costs, expenses and
               liabilities which might be incurred by it in compliance with such
               request or direction;

<PAGE>   55

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

                    (7) 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.

               SECTION 6.04 Not Responsible for Recitals or Issuance of
Securities.

               The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities. The Trustee shall not be accountable for the use
or application by the Company of Securities or the proceeds thereof. The Trustee
shall not have any responsibility or liability for any information provided to
Holders or any other Person, including without limitation in the solicitation of
any consent or waiver hereunder, or pursuant to any offering documents, or
pursuant to any Offer to Purchase.

               SECTION 6.05 May Hold Securities.

               The Trustee, any Authenticating Agent, any Paying Agent, any
Security Registrar or any other agent of the Company, in its individual or any
other capacity, may become the owner or pledgee of Securities and, subject to
Sections 6.08 and 6.13, may otherwise deal with the Company with the same rights
it would have if it were not Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other agent.

               SECTION 6.06 Money Held in Trust.

               Money held by the Trustee in trust hereunder need not be

except as otherwise agreed with the Company.

trustee of an express trust);

               (b) except as otherwise expressly provided herein, to reimburse
the Trustee upon its request for all reasonable expenses, disbursements and
advances incurred or made by the Trustee in accordance with any provision of
this Indenture (including the reasonable compensation and the expenses

                                       48
<PAGE>   56

and disbursements of its agents and counsel), except any such expense,
disbursement or advance as may be attributable to its negligence, willful

               (c) to indemnify the Trustee for, and to hold it harmless
against, any loss, liability or expense incurred without negligence, willful
misconduct or bad faith on its part (subject to the provisions of Sections 6.01
and 6.03), arising out of or in connection with the acceptance or administration
of this trust, including the reasonable costs and expenses of defending itself
against any claim or liability in connection with the exercise or performance of
any of its powers or duties hereunder. The Trustee shall notify the Company
promptly of any claim for which it may seek indemnity. Failure by the Trustee to
notify the Company shall not relieve the Company of its obligations hereunder.

               SECTION 6.08 Disqualification: Conflicting Interests.

               If the Trustee has or shall acquire a conflicting interest within

               SECTION 6.09 Corporate Trustee Required; Eligibility.

requirements of said supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus of such Person shall be deemed

condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

               SECTION 6.10 Resignation and Removal; Appointment of Successor.

               (a) No resignation or removal of the Trustee and no appointment

acceptance of appointment by the successor Trustee under Section 6.11.

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

               (c) The Trustee may be removed at any time by Act of the Holders
of a majority in aggregate stated amount at Maturity of the Outstanding
Securities, delivered to the Trustee and to the Company.

<PAGE>   57

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

                    then, in any such case, (A) the Company by a Board
                    Resolution may remove the Trustee, or (B) subject to Section
                    5.14, any Holder who has been a bona fide Holder of a
                    Security for at least six months may, on behalf of himself
                    and all others similarly situated, petition any court of
                    competent jurisdiction for the removal of the Trustee and
                    the appointment of a successor Trustee.

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

               (f) The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to all
Holders in the manner provided in Section 1.06. Each notice shall include the
name of the successor Trustee and the address of its Corporate Trust Office.

               SECTION 6.11 Acceptance of Appointment by Successor.

               (a) Every successor Trustee appointed hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; but, on request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of
its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder. Upon request of any such successor
Trustee, the Company shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights,
powers and trusts.

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

               SECTION 6.12 Merger, Conversion, Consolidation or Succession to
Business.

               Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall

                                       50
<PAGE>   58

be otherwise qualified and eligible under this Article, without the execution or
filing of any paper or any further act on the part of any of the parties hereto.
In case any Securities shall have been authenticated, but not delivered, by the
Trustee then in office, any successor by merger, conversion or consolidation to
such authenticating Trustee may adopt such authentication and deliver the
Securities so authenticated with the same effect as if such successor Trustee
had itself authenticated such Securities.

               SECTION 6.13 Preferential Collection of Claims Against Company.

               If and when the Trustee shall be or become a creditor of the
Company (or any other obligor upon the Securities), the Trustee shall be subject
to the provisions of the Trust Indenture Act regarding the collection of claims
against the Company (or any such other obligor).

               SECTION 6.14 Appointment of Authenticating Agent.

               (a) The Trustee may appoint an Authenticating Agent or Agents
which shall be authorized to act on behalf of the Trustee to authenticate
Securities issued upon original issue and upon exchange, registration of
transfer, partial conversion or partial redemption or pursuant to Section 3.06,
and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States, any State thereof or the District of
Columbia, authorized under such laws to act as Authenticating Agent, having a
combined capital and surplus of not less than $50,000,000 and subject to
supervision or examination by Federal or State authority. If such Authenticating
Agent publishes reports of condition at least annually, pursuant to law or to
the requirements of said supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions to this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

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

               (c) An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee and to the Company. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders as their
names and addresses appear in the Security Register. Any successor
Authenticating Agent upon

                                       51
<PAGE>   59

acceptance of its appointment hereunder shall become vested with all the rights,
powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

               (d) The Trustee agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its services under this Section, and
the Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 6.07.

               (e) If an appointment is made pursuant to this Section, the
Securities may have endorsed thereon, in addition to the Trustee's certificate
of authentication, an alternative certificate of authentication in the following
form:

               supplemental indenture, complies with this Article and that all
               conditions precedent herein provided for relating to such

Company into, any other Person or any transfer, conveyance, sale, lease or other
disposition of all or substantially all of the properties and assets of the

shall be known as the "Successor Company"), the Successor Company shall succeed
to, and be substituted for, and may exercise every right and power of, the
Company under this Indenture with the same effect as if such successor Person
had been named as the Company herein, and thereafter, except in the case of a
lease, the predecessor Person shall be relieved of all obligations and covenants

                    (5) to cure any ambiguity, to correct or supplement any
               provision herein which may be inconsistent with any other
               provision herein, or to make any other provisions with respect to
               matters or questions arising under this Indenture which shall not
               be inconsistent with the provisions of this Indenture, provided
               such action pursuant to this clause (5) shall not adversely
               affect the interests of the Holders in any material respect; or

                    (6) to issue Additional Securities as provided in Section

               SECTION 9.02 Supplemental Indentures with Consent of Holders.

               (a) With the consent of the Holders of not less than a majority
in aggregate principal amount of the Outstanding Securities, by Act of said

               or any installment of interest on, any Security, or

                    (2) reduce the principal amount of, any premium payable, or

               necessary to modify or amend this Indenture, or

<PAGE>   63

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

               SECTION 9.03 Execution of Supplemental Indentures.

               In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Sections 6.01 and 6.03) shall be fully protected in relying
upon, an Opinion of Counsel stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture. The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

               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 Securities 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

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

Outstanding Securities.

                                   ARTICLE X
                                   COVENANTS

               SECTION 10.01 Payment of Stated Amount at Maturity, Premium and
Interest.

               The Company will duly and punctually pay the stated amount at

with the terms of the Securities and this Indenture.

               SECTION 10.02 Maintenance of Office or Agency.

               (a) The Company will maintain in the Borough of Manhattan, The
City of New York, an office or agency where Securities may be presented or
surrendered for payment, where Securities may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities and this Indenture may be served. The Company will
give prompt written notice to the Trustee of the location, and any change in the
location, of such office or

                                       56
<PAGE>   64

agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee in New York, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

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

               SECTION 10.03 Money for Security Payments to be Held in Trust.

               (a) If the Company shall at any time act as its own Paying Agent,
it will, on or before each due date of the stated amount at Maturity of (and
premium, if any) or interest on any of the Securities, segregate and hold in
trust for the benefit of the Persons entitled thereto a sum sufficient to pay
the stated amount at Maturity (and premium, if any) or interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

               (b) Whenever the Company shall have one or more Paying Agents, it
will, prior to each due date of the stated amount at Maturity of (and premium,
if any) or interest on any Securities, deposit with a Paying Agent a sum
sufficient to pay the stated amount at Maturity (and premium, if any) or
interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such stated amount at Maturity, premium or interest, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of its action or failure so to act.

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

                    (1) hold all sums held by it for the payment of the stated
               amount at Maturity of (and premium, if any) or interest on
               Securities in trust for the benefit of the Persons entitled
               thereto until such sums shall be paid to such Persons or
               otherwise disposed of as herein provided;

                    (2) give the Trustee notice of any Default by the Company
               (or any other obligor upon the Securities) in the making of any
               payment of the stated amount at Maturity (and premium, if any) or
               interest; and

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

               (d) The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such

                                       57
<PAGE>   65

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.

               (e) Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the stated amount at
Maturity of (and premium, if any) or interest on any Security and remaining
unclaimed for two years after such principal (and premium, if any) or interest
has become due and payable shall be paid to the Company on Company Request, or
(if then held by the Company) shall be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor, look
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in a newspaper
published in the English language, customarily published on each Business Day
and of general circulation in The City of New York, notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such publication, any unclaimed balance of
such money then remaining will be repaid to the Company.

               SECTION 10.04 Corporate Existence.

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

               SECTION 10.05 Maintenance of Properties.

               The Company will cause all material properties used or useful in
the conduct of its business or the business of any Subsidiary of the Company to
be maintained and kept in good condition, repair and working order and supplied
with all necessary equipment and will cause to be made all necessary repairs,
renewals, replacements, betterments and improvements thereof, all as in the
judgment of the Company may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times;
provided, however, that nothing in this Section shall prevent the Company from
discontinuing the operation or maintenance of any of such properties if such
discontinuance is, as determined by the Board of Directors in good faith,
desirable in the conduct of its business or the business of any Subsidiary and
not disadvantageous in any material respect to the Holders.

               SECTION 10.06 Payment of Taxes and Other Claims.

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

                                       58

               SECTION 10.07 Maintenance of Insurance.

               The Company shall, and shall cause its Subsidiaries to, keep at
all times all of their properties which are of an insurable nature insured
against loss or damage with insurers believed by the Company to be responsible
to the extent that property of similar character is usually so insured by
corporations similarly situated and owning like properties in accordance with
good business practice.

               SECTION 10.08 Limitation on Liens.

               The Company may not, directly or indirectly, Incur, assume or
suffer to exist any Lien on or with respect to any property or assets, now owned
or hereafter acquired, to secure any present or future Relevant Debt without
making effective provision for securing the Securities:

                    (1) in the event such Debt is pari passu with the
               Securities, equally and ratably with such Debt as to such
               property or assets for so long as such Debt will be so secured,
               or

                    (2) in the event such Debt is subordinate in right of
               payment to the Securities, prior to such Debt as to such property
               or assets for so long as such Debt will be so secured.

               SECTION 10.09 Change of Control Triggering Event.

               (a) Within 30 days of the occurrence of a Change of Control
Triggering Event, the Company will be required to make an Offer to Purchase all
Outstanding Securities at a purchase price equal to 101% of the principal amount
thereof plus accrued and unpaid interest (including any Additional Interest), if
any, to the date of purchase.

               (b) A "Change of Control" will be deemed to occur at such time as
either:

                    (1) a "person" or "group" (within the meaning of Sections
               13(d) and 14(d)(2) of the Exchange Act), other than any Permitted
               Holder, becomes the ultimate "beneficial owner" (as defined in
               Rule 13d-3 under the Exchange Act and including by reason of any
               change in the ultimate "beneficial ownership" of the Capital
               Stock of the Company) of more than 50% of the total voting power
               of the Voting Stock of the Company (calculated on a fully diluted
               basis); or

                    (2) individuals who at the beginning of any period of two
               consecutive calendar years constituted the Board of Directors of
               the Company (together with any new directors whose election by
               such Board of Directors or whose nomination for election was
               approved by a vote of at least two-thirds of the members of such
               Board of Directors then still in office who either were members
               of such Board of Directors at the beginning of such period or
               whose election or nomination for election was previously so
               approved) cease for any reason to constitute at least 50% of the
               members of such Board of Directors then in office.

               (c) The Company will not be required to make an Offer to Purchase
any Securities upon a Change of Control Triggering Event if it has exercised its
right to redeem all of the Securities as described under Article X1 in the
manner, at the times and otherwise in compliance with the requirements set forth
in this Indenture applicable to an Offer to Purchase made by the Company and
purchases all of the Securities validly tendered and not withdrawn under such an
Offer to Purchase.

<PAGE>   67

               (d) If the Company fails to make the Offer to Purchase or fails
to pay the purchase price and accrued interest described above on the date
specified therefor, the Trustee and the Holders of Securities will have the
rights described under Section 5.01.

               (e) In the event that the Company makes an Offer to Purchase the
Securities, the Company shall comply with any applicable securities laws and
regulations, including any applicable requirements of Section 14(e) of, and Rule
14e-1 under, the Exchange Act.

               SECTION 10.10 Provision of Financial Information.

               (a) Whether or not the Company is required to be subject to
Section 13(a) or 15(d) of the Exchange Act, the Company shall file with the
Commission copies of the annual reports, quarterly reports and other documents
which the Company would have been required to file with the Commission pursuant
to such Section 13(a) or 15(d) or any successor provision thereto if the Company
were so required, such documents to be filed with the Commission on or prior to
the respective dates (the "Required Filing Dates") by which the Company would
have been required to file such documents if the Company were so required. The
Company shall also in any event:

                    (1) within 15 days of each Required Filing Date,

                         (i) transmit by mail to all Holders of the Securities,
                    as their names and addresses appear in the Security
                    Register, without cost to such Holders, and

                         (ii) file with the Trustee, copies of the annual
                    reports, quarterly reports and other documents which the
                    Company files with the Commission pursuant to such Section
                    13(a) or 15(d) or any successor provision thereto or would
                    have been required to file with the Commission pursuant to
                    such Section 13(a) or 15(d) or any successor provisions
                    thereto if the Company were required to be subject to such
                    Sections, and

                    (2) if filing such documents by the Company with the
               Commission is not permitted under the Exchange Act, promptly upon
               written request, supply copies of such documents to any
               prospective Holder of Securities'.

               SECTION 10.11 Statement By Officers as to Default; Compliance
Certificates.

               (a) The Company will deliver to the Trustee, within 120 days

Company ending after the date hereof an Officers' Certificate, stating that,
after conducting a review of the activities of the Company and its Subsidiaries
and of the Company's and its Subsidiaries performance under this Indenture, the
Company has fulfilled all obligations thereunder, or whether the Company is in
default in the performance and observance of any of the terms, provisions and
conditions of this Indenture, and if the Company shall be in Default, specifying
all such Defaults and the nature and status thereof of which it has knowledge.

               (b) The Company shall deliver to the Trustee, as soon as possible
and in any event within 10 days after the Company becomes aware of the
occurrence of an Event of Default or an event which, with notice or the lapse of
time or both, would constitute an Event of Default, an Officers' Certificate
setting forth the details of such Event of Default or default, and the action
which the Company proposes to take with respect thereto.

               SECTION 10.12 Waiver of Certain Covenants.

               The Company may omit in any particular instance to comply with
any covenant or condition set forth in Section 8.01, Sections 10.04 to 10.11,
inclusive, and Sections 10.13 to 10.14, inclusive, if before the time for such
compliance the Holders of at least a majority in stated amount at Maturity of
the Outstanding Securities shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such covenant or condition shall remain in full force and
effect; provided, however, with respect to an Offer to Purchase as to which an
Offer has been mailed, no such waiver may be made or shall be effective against
any Holder tendering Securities pursuant to such Offer, and the Company may not
omit to comply with the terms of such Offer as to such Holder.

               SECTION 10.13 Indemnification of Judgment Currency.

               The Company shall indemnify the Trustee and any Holder against
any loss incurred by the Trustee or such Holder, as the case may be, as a result
of any judgment or order being given or made for any amount due under this
Indenture or such Security (by reason of the Company being in default under this
Indenture) and being expressed and paid in a currency (the "Judgment Currency")
other than U.S. Dollars, and as a result of any variation between (i) the rate
of exchange at which the U.S. Dollar amount is converted into the Judgment
Currency for the purpose of such judgment or order and (ii) the spot rate of
exchange in The City of New York at which the Trustee or such Holder, as the
case may be, on the date that the amount of the Judgment Currency is actually
received by the Trustee or such Holder. The foregoing indemnity shall constitute
a separate and independent obligation of the Company and shall continue in full
force and effect notwithstanding any such judgment or order as aforesaid. The
term "spot rate of exchange" shall include any premiums and costs of exchange
payable in connection with the purchase of, or conversion into, U.S. Dollars as
quoted by The Bank of New York at its central foreign exchange desk in its head
office in New York City at 12:00 noon.

               SECTION 10.14 Payments for Consent.

               The Company shall not, and shall not permit any of its
Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest, fee or otherwise, to any Holder of
the Securities for or as an inducement to any consent, waiver or amendment of
any of the terms or provisions of this Indenture or the Securities unless such
consideration is offered to be paid or is paid to all Holders of the Securities
that consent, waive or agree to amend in the time frame set forth in the
solicitation documents relating to such consent, waiver or agreement.

               SECTION 10.15 Additional Amounts.

               (a) All payments made by the Company under or with respect to the
Securities 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 (hereinafter "Taxes") imposed or levied by or on
behalf of any Taxing Jurisdiction, unless the Company is required to withhold or
deduct Taxes by law or by the interpretation or administration thereof. If the
Company is so required to withhold or deduct any amount of interest for or on
account of Taxes from any payment made under or with respect to the Securities,
the Company shall pay such additional amounts of interest ("Additional Amounts")
as may be necessary so that the net amount received by each Holder (including
Additional Amounts) after such withholding or deduction shall not be less than
the amount the Holder would have received if such Taxes

                                       61
<PAGE>   69

had not been withheld or deducted; provided, however, that the Company will not
pay any Additional Amounts in connection with any Taxes that are imposed due to
any of the following ("Excluded Additional Amounts"):

                    (1) the Holder or beneficial owner has some connection with
               the Taxing Jurisdiction other than merely holding the Securities
               or receiving principal or interest payments on the Securities
               (such as citizenship, nationality, residence, domicile, or
               existence of a business, a permanent establishment, a dependent
               agent, a place of business or a place of management present or
               deemed present within the Taxing Jurisdiction);

                    (2) any tax imposed on, or measured by net income;

                    (3) the Holder or beneficial owner fails to comply with any
               certification, identification or other reporting requirements
               concerning its nationality, residence, identity or connection
               with the Taxing Jurisdiction, if (A) such compliance is required
               by applicable law, regulation, administrative practice or treaty
               as a precondition to exemption from all or a part of the Tax, (B)
               the Holder or beneficial owner is able to comply with such
               requirements without undue hardship, and (C) at least 30 calendar
               days prior to the first payment date with respect to which such
               requirements under the applicable law, regulation, administrative
               practice or treaty shall apply, the Company has notified such
               Holder that such Holder will be required to comply with such
               requirements;

                    (4) the Holder fails to present (where presentation is
               required) its Security within 30 calendar days after the Company
               has made available to the Holder a payment of principal or
               interest, provided that the Company will pay Additional Amounts
               which a Holder would have been entitled to had the Security owned
               by such Holder been presented on any day (including the last day)
               within such 30-day period;

                    (5) any estate, inheritance, gift, value added, use or sales
               Taxes or any similar Taxes;

                    (6) where any Additional Amounts are imposed on a payment on
               the Securities to an individual and are required to be made
               pursuant to any European Union Directive on the taxation of
               savings implementing the conclusions of the Economic and
               Financial Council of Ministers of the member states of the
               European Union (ECOFIN) Council meeting of November 26-27, 2000
               or any law implementing or complying with, or introduced in order
               to conform to, such Directive; or

                    (7) where the Holder or beneficial owner could avoid any
               Additional Amounts by requesting that a payment on the Securities
               be made by, or presenting the relevant Securities for payment to,
               another Paying Agent located in a Member State of the European
               Union.

               (b) The Company shall also (1) make such withholding or deduction
and (2) remit the full amount deducted or withheld to the relevant authority in
accordance with applicable law. The Company shall furnish to the Holders of the
Securities, within 30 days after the date the payment of any Taxes are due
pursuant to applicable law, certified copies of tax receipts evidencing such
payment by the Company.

                                       62
<PAGE>   70

               (c) The Company shall indemnify and hold harmless each Holder for
the amount (other than Excluded Additional Amounts) of (1) any Taxes not
withheld or deducted by the Company and levied or imposed and paid by such
Holder as a result of payments made under or with respect to the Securities, (2)
any liability (including penalties, interest and expenses) arising therefrom or
with respect thereto, and (3) any Taxes imposed with respect to any
reimbursement under clause (1) or (2) of this paragraph (c) of this Section
10.15.

               (d) At least 30 days prior to each date on which any payment
under or with respect to the Securities is due and payable, if the Company is
aware that it will be obligated to pay Additional Amounts with respect to such
payment, the Company shall deliver to the Trustee an Officers' Certificate
stating the fact that such Additional Amounts will be payable, the amounts so
payable and such other information necessary to enable the Trustee to pay such
Additional Amounts to Holders on the payment date. Whenever in this Indenture
there is mentioned, in any context, the payment of principal (and premium, if
any), interest or any other amount payable under or with respect to any
Security, such mention (except where expressly mentioned) shall be deemed to
include mention of the payment of Additional Amounts provided for in this
Section 10.15 to the extent that, in such context, Additional Amounts are, were
or would be payable in respect thereof.

                                   ARTICLE XI
                            REDEMPTION OF SECURITIES

               SECTION 11.01 Right of Redemption.

               (a) At the Company's option, the Company may redeem the
Securities in whole or in part at any time at a redemption price equal to the
greater of (i) 100% of the principal amount of the Securities to be redeemed and
(ii) the sum of the present values of the remaining scheduled payments of
principal and interest on the Securities to be redeemed (excluding the portion
of any such interest accrued to the Redemption Date) discounted to the
Redemption Date on a semi-annual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Yield, plus 50 basis points, plus, in each
case, accrued and unpaid interest to the Redemption Date.

               (b) At the Company's option, the Company may redeem the
Securities in whole, but not in part, at any time at a redemption price equal to
100% of the principal amount of the Securities to be redeemed together with
accrued and unpaid interest thereon to the Redemption Date, and any other
amounts owed to the Holders of the Securities under the terms of this Indenture
or the Securities, upon notice mailed to each Holder of Securities at the
addresses appearing in the Security Register, if, as a result of any change or
amendment to the laws (or regulations promulgated thereunder) of any Taxing
Jurisdiction, or any change in or amendment to any official position or
administration or assessing practices regarding the application or
interpretation of such laws or regulations, which change or amendment is
announced or becomes effective on or after June 22, 2001, the Company has become
or would become obligated to pay, on the next date on which any amount would be
payable under or with respect to the Securities, any Additional Amounts, to a
Holder in accordance with Section 10.15 hereof, provided that the Company
determines, in its business judgment, that the obligation to pay such Additional
Amounts cannot be avoided by the use of reasonable measures available to the
Company which would not involve any liability of any kind to the Company, except
for any cost or expense which is minimal, not including substitution of the
obligor under the Securities.

               SECTION 11.02 Applicability of Article.

               Redemption of Securities at the election of the Company or
otherwise, as permitted or required by any provision of this Indenture, shall be
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 the Securities shall be
evidenced by a Board Resolution. In case of any redemption at the election of
the Company, the Company shall, not less than 30 days nor more than 60 days
prior to the Redemption Date fixed by it (unless a shorter notice period shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date and
of the principal amount of Securities to be redeemed. Such notice shall be
accompanied by an Officers' Certificate and an Opinion of Counsel from the
Company to the effect that such redemption shall comply with the conditions
herein.

               SECTION 11.04 Selection by Trustee of Securities to Be Redeemed.

               (a)  If less than all the Securities are to be redeemed, the
                    particular Securities to be redeemed shall be selected not
                    more than 60 days prior to the Redemption Date by the
                    Trustee, from the Outstanding Securities not previously
                    called for redemption, by such method as the Trustee shall
                    deem fair and appropriate and which may provide for the
                    selection for redemption of portions of the principal of
                    Securities; provided, however, that no such partial
                    redemption shall reduce the portion of the principal amount
                    of a Security not redeemed to less than $1,000. Securities
                    and any portions of such Securities selected by the Trustee
                    shall be in amounts of $1,000 or integral multiples thereof.

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

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

               SECTION 11.05 Notice of Redemption.

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

               All notices of redemption shall state:

               (a)  the principal amount of each Security held by such Holder to
                    be redeemed;

               (b)  the Redemption Date;

               (c)  the Redemption Price;

<PAGE>   72

               (d)  that on the Redemption Date the Redemption Price will become
                    due and payable upon each such Security, and that interest
                    thereon shall cease to accrue on and after said date;

               (e)  the CUSIP number;

               (f)  if fewer than all of the Outstanding Securities are to be
                    redeemed, then the identification and principal amounts at
                    Maturity of the particular Securities to be redeemed; and

               (g)  the place or places where such Securities are to be
                    surrendered for payment of the Redemption Price.

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

               SECTION 11.06 Deposit of Redemption Price.

               On or prior to any Redemption Date, the Company shall deposit or
cause to be deposited with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 10.03) an amount of money in same day funds (or New York
Clearing House funds if such deposit is made prior to the applicable Redemption
Date) sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.

               SECTION 11.07 Securities Payable on Redemption Date.

               (a)  Notice of redemption having been given as aforesaid, the
                    Securities so to be redeemed shall, on the Redemption Date,
                    become due and payable at the Redemption Price therein
                    specified and from and after such date (unless the Company
                    shall default in the payment of the Redemption Price and
                    accrued interest) such Securities shall cease to bear
                    interest. Upon surrender of any such Security for redemption
                    in accordance with said notice, such Security shall be paid
                    by the Company at the Redemption Price together with accrued
                    interest to the Redemption Date; provided, however, that
                    installments of interest whose Stated Maturity is on or
                    prior to the Redemption Date shall be payable to the Holders
                    of such Securities, or one or more Predecessor Securities,
                    registered as such on the relevant Regular Record Dates
                    according to the terms and the provisions of Section 3.07.

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

               SECTION 11.08 Securities Redeemed in Part.

               Any Security that is to be redeemed only in part shall be
surrendered to the Paying Agent at the office of the Paying Agent or to the
office or agency referred to in Section 10.02 (with, if the Company or the
Trustee so require, 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 the
Trustee shall authenticate and deliver to the Holder of such Security, without
service charge, a replacement Security or Securities, of any authorized
denomination as requested by such Holder in an aggregate principal amount equal
to, and in exchange for, the principal amount of the Security so surrendered
that is not redeemed.

Twelve.

Company shall be deemed to have paid and discharged the entire indebtedness
represented by the Outstanding Securities and to have satisfied all its other

are concerned (and the Trustee, at the expense of the Company, shall execute
proper instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of such Securities to receive, solely from the trust fund described in

10.10, inclusive and Section 10.15), 5.01(a)(5), 5.01(a)(6) and 5.01(a)(8) shall

limitation set forth in any such Section, Clause or Article, whether directly or
indirectly by reason of any reference elsewhere herein to any such Section,

               the requirements of Section 6.09 who shall agree to comply with
               the provisions of this Article Twelve applicable to it) as trust
               funds in trust for the purpose of making the following payments,

               amount, or (B) United States 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, money in an
               amount, or (C) a combination thereof, sufficient, in the opinion
               of a nationally recognized firm of independent certified public
               accountants expressed in a written certification thereof
               delivered to the Trustee, to pay and discharge, and which shall
               be applied by the Trustee (or other qualifying trustee) to pay
               and discharge, the principal of (premium, if any) and each
               installment of interest, if any, on the Outstanding Securities on

               principal or installment of interest in accordance with the terms
               of this Indenture and of such Securities. For this purpose,
               "United States Government Obligations" means securities that are
               (x) direct obligations of the United States for the payment of
               which its full faith and credit is pledged or (y) obligations of
               a Person controlled or supervised by and acting as an agency or
               instrumentality of the United States the payment of which is
               unconditionally guaranteed as a full faith and credit obligation
               by the United States, 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 United States Government Obligation or a specific
               payment of principal of or interest on any such United States
               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 United States Government Obligation or the
               specific payment of principal of or interest on the United States
               Government Obligation evidenced by such depository receipt.

                    (2) In the case of an election under Section 12.02, the
               Company has delivered to the trustee (A) either (i) an Opinion of
               Counsel to the effect that Holders will not recognize income,
               gain or loss for U.S. federal income tax purposes as a result of
               such deposit, defeasance and discharge and will be subject to
               U.S. federal income tax on the same amount and in the same manner
               and at the same times as would have been the case if such
               deposit, defeasance and discharge had not occurred, which Opinion
               of Counsel must be based upon (and accompanied by copy of) a
               ruling of the Internal Revenue Service to the same effect or
               based upon a change in applicable U.S. federal income tax law
               after the date of the indenture or (ii) a ruling directed to the
               trustee received from the Internal Revenue Service to the same
               effect as the aforementioned Opinion of Counsel and (B) an
               Opinion of Counsel to the effect that the creation of the
               defeasance trust does not violate the Investment Company Act of
               1940, as amended, and, after the passage of 123 days following
               the deposit, the trust fund will not be subject to

                                       67
<PAGE>   75

               the effect of Section 547 of the United States Bankruptcy Code or
               Section 15 of the New York Debtor and Creditor Law.

                    (3) Immediately after giving effect to such deposit on a pro
               forma basis, no Event of Default, or event that after the giving
               of notice or lapse of time or both would become an Event of
               Default, shall have occurred and be continuing on the date of
               such deposit or during the period ending on the 123rd day after
               the date of such deposit, and such deposit shall not result in a
               breach or violation of, or constitute a default under, any other
               agreement or instrument to which The Company is a party or by
               which the Company is bound.

                    (4) If at such time the Securities are listed on a national
               securities exchange, the Company has delivered to the trustee an
               Opinion of Counsel to the effect that the Securities will not be
               delisted as a result of such deposit, defeasance and discharge.

                    (5) Such deposit, defeasance or covenant defeasance and
               discharge shall not result in a breach or violation of, or
               constitute a default under, any other agreement or instrument to
               which the Company or any Subsidiary is a party or by which the
               Company or any Subsidiary is bound.

                    (6) The Company shall have delivered to the Trustee an
               Officers' Certificate and an Opinion of Counsel, each stating
               that all conditions precedent provided for relating to either the
               defeasance under Section 12.02 or the covenant defeasance under
               Section 12.03 (as the case may be) have been complied with.

               (b) (i) The provisions described in clauses (1), (2)(B), (3) and
(4) in Subsection (a) and (ii) the delivery by the Company or the Trustee of an
Opinion of Counsel to the effect that, among other things, the Holders will not
recognize income, gain or loss for federal income tax purposes as a result of
such deposit and defeasance of certain covenants and Events of Default and will
be subject to U.S. federal income tax on the same amount and in the same manner
and at the same times as would have been the case if such deposit and defeasance
had not occurred, shall be conditions to the application of Section 12.03 to the
then Outstanding Securities.

               SECTION 12.05 Deposited Money and United States Government
Obligations to be Held in Trust: Other Miscellaneous Provisions.

               (a) Subject to the provisions of the last paragraph of Section
10.03, all money and United States Government Obligations (including the
proceeds thereof) deposited with the Trustee (or other qualifying
trustee--collectively, for purposes of this Section 12.05, the "Trustee")
pursuant to Section 12.04 in respect of the Securities shall be held in trust
and applied by the Trustee, in accordance with the provisions of such Securities
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due
thereon in respect of principal (and premium, if any) and interest, but such
money need not be segregated from other funds except to the extent required by
law.

               (b) The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the United States
Government Obligations deposited pursuant to Section 12.04 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 Outstanding
Securities.

                                       68
<PAGE>   76

               (c) Anything in this Article Twelve to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company from time to
time upon Company Request any money or United States Government Obligations held
by it as provided in Section 12.04 which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount
thereof which would then be required to be deposited to effect an equivalent
defeasance or covenant defeasance.

               SECTION 12.06 Reinstatement.

               If the Trustee or the Paying Agent is unable to apply any money
in accordance with Section 12.02 or 12.03 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 Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article Twelve until such time as the
Trustee or Paying Agent is permitted to apply all such money in accordance with
Section 12.02 or 12.03; provided, however, that if the Company makes any payment
of stated amount at Maturity of (and premium, if any) or interest on any
Security following the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Securities to receive such
payment from the money held by the Trustee or the Paying Agent.

               This Indenture may be executed in any number of counterparts,
each of which so executed shall be deemed to be an original, but all such

                                  ----------------------------------------------

The person in whose name this certificate is executed below (the "Undersigned")
hereby certifies that either (i) it is the sole beneficial owner of the

                         (i) at the time the buy order was originated, the
                    Transferee was outside the United States or the Owner and
                    any person acting on its behalf reasonably believed that the
                    Transferee was outside the United States, or

                         (ii) the transaction is being executed in, on or

                    designated offshore securities market and neither the Owner
                    nor any person acting on its behalf knows that the
                    transaction has been prearranged with a buyer in the United
                    States;

               (4)  no directed selling efforts in contravention of the
                    requirements of Rule 904(b) have been made in the United
                    States by or on behalf of the Owner or any affiliate
                    thereof; and

               (5)  the transaction is not part of a plan or scheme to evade the
                    registration requirements of the Securities Act.

               Reference is hereby made to the Indenture, dated as of June 22,
2001 (the "Indenture"), among Teekay Shipping Corporation and U.S. Trust Company
of Texas, N.A., as Trustee. Terms used but not defined herein and defined in
Rule 144A or in the Indenture shall have the meanings given to them in Rule 144A
or the Indenture, as the case may be.

               This certificate relates to U.S. $_______________ stated amount
at maturity of Securities, which are evidenced by the following certificate(s)

The person in whose name this certificate is executed below (the "Undersigned")
hereby certifies that either (i) it is the sole beneficial owner of the
Specified Securities or (ii) it is acting on behalf of all the beneficial owners
of the Specified Securities and is duly authorized by them to do so. Such
beneficial owner or owners are referred to herein collectively as the "Owner".
If the Specified Securities are represented by a Global Security, they are held
through the United States Depositary or an Agent Member in the name of the
Undersigned, as or on behalf of the Owner. If the Specified Securities are not
represented by a Global Security, they are registered in the name of the
Undersigned, as or on behalf of the Owner.

               The Owner has requested that the Specified Securities be
transferred to a person (the "Transferee") who will take delivery in the form of
a Restricted Security or an interest therein. In connection with such transfer,
the Owner hereby certifies that such transfer is being effected in accordance
with Rule 144A under the Securities Act and all applicable securities laws of
the states of the United States and other jurisdictions. Accordingly, the Owner
hereby further certifies as:

               (1)  the Specified Securities are being transferred to a person
                    that the Owner and any person acting on its behalf
                    reasonably believe is a "qualified institutional buyer"
                    within the meaning of Rule 144A, acquiring for its own
                    account or for the account of a qualified institutional
                    buyer; and

               (2)  the Owner and any person acting on its behalf have taken
                    reasonable steps to ensure that the Transferee is aware that
                    the Owner may be relying on Rule 144A in connection with the
                    transfer.

               Upon giving effect to this request to exchange a beneficial
interest in Regulation S Global Securities for a beneficial interest in the
Restricted Global Security, the resulting beneficial interest shall be subject
to the restrictions on transfer applicable to the Restricted Global Securities
pursuant to the Indenture and the Securities Act.

<PAGE>   4

                                [Reverse of Note]

               This Security is one of a duly authorized issue of Securities of
the Company designated as its 8.875% Senior Notes due July 15, 2011 (herein
called the "Securities"), issued and to be issued under an indenture dated as of
June 22, 2001 (herein called the "Indenture"), between the Company and U.S.
Trust Company of Texas, N.A., as Trustee (herein called the "Trustee", which
term includes any successor trustee under the Indenture), to which Indenture and
all indentures supplemental thereto reference is hereby made for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee and the Holders of the Securities and of the terms
upon which the Securities are, and are to be, authenticated and delivered.

               As provided for in the Indenture, the Company may, subject to
certain limitations, from time to time, without notice or other consent of the
Holders, create and issue Additional Securities ranking pari passu with the
Securities issued the date hereof so that such Additional Securities shall be
consolidated and form a single series with the Securities initially issued by
the Company and shall have the same terms as to status, redemption or otherwise
as Securities originally issued. Any Additional Securities shall be issued with
the benefit of any indenture supplemental to the Indenture.

               At the Company's option, the Company may redeem the Securities in
whole or in part at any time at a redemption price equal to the greater of (i)
100% of the principal amount of the Securities to be redeemed and (ii) the sum
of the present values of the remaining scheduled payments of principal and
interest on the Securities to be redeemed (excluding the portion of any such
interest accrued to the Redemption Date) discounted to the Redemption Date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Treasury Yield, plus 50 basis points, plus, in each case, accrued and
unpaid interest to the Redemption Date.

               The Securities shall be subject to redemption, at the option of
the Company, as a whole but not in part, at any time upon not fewer than 30 nor
more than 60 days' notice mailed to each Holder of Securities at the addresses
appearing in the Security Register at a redemption price equal to 100% of the
principal amount of the Securities plus accrued interest to but excluding the
Redemption Date if the Company has become or would become obligated to pay on
the next date on which any amount would be payable under or with respect to the
Securities, any Additional Amounts as a result of any change or amendment to the
laws (including any regulations promulgated thereunder) of any Taxing
Jurisdiction, or any change in or amendment to any official position regarding
the application or interpretation of such laws or regulations, which change or
amendment is announced or becomes effective on or after June 22, 2001.

               If less than all of the Securities are to be redeemed at any
time, the Trustee shall select the Securities to be redeemed by such method as
the Trustee shall deem fair and appropriate in the aggregate principal amount
specified by the Company. The Trustee may select for redemption Securities and
portions of Securities in amounts of U.S.$1,000 or whole multiples of
U.S.$1,000.

               The Securities do not have the benefit of any sinking fund
obligations.

               In the event of redemption or purchase pursuant to an Offer to
Purchase of this Security in part only, a new Security or Securities for the
unredeemed or unpurchased portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof.

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

               The Indenture provides that, subject to certain conditions, if a
Change of Control Triggering Event occurs, the Company shall be required to make
an Offer to Purchase for all or a specified portion of the Securities.

covenants and Events of Default with respect to this Security, in each case upon
compliance with certain conditions set forth therein.

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

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

               As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in the Borough of Manhattan, the City of New
York, duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Security Registrar duly executed by,
the Holder hereof or his attorney duly authorized in writing, and thereupon one
or more new Securities, of authorized denominations and for the same aggregate
stated amount at maturity, will be issued to the designated transferee or
transferees.

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

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

               Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security be overdue, and neither

contrary.
