<PAGE>

                  (e)      The definitive registered Securities shall be typed,
printed, lithographed or engraved or produced by any combination of these
methods or may be produced in any other manner permitted by the rules of any

evidenced by their execution of such Securities.

SECTION 2.3       EXECUTION AND AUTHENTICATION.

                  (a)      One Officer shall sign the Securities for the Company
by manual or facsimile signature.

                  (b)      If an Officer whose signature is on a Security no
longer holds that office at the time the Security is authenticated, the Security
shall nevertheless be valid.

                  (c)      A Security shall not be valid until authenticated by
the manual signature of an authorized officer of the Trustee. The signature
shall be conclusive evidence that the Security has been authenticated under this
Indenture.

                  (d)      The Trustee shall authenticate Securities upon
receipt of a written order of the Company signed by two Officers. Such order
shall specify the Series and the amount of the Securities to be authenticated
and the date on which such Securities are to be authenticated. The aggregate
principal amount of Securities outstanding at any time is unlimited. In
authenticating such Securities and in accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive and shall be fully protected in relying upon, an Opinion of
Counsel (which may rely upon an Officers' Certificate as to factual matters)
stating:

                           (i)      that the form or forms of such Securities
have been established in conformity with the provisions of this Indenture;

                           (ii)     that the terms of such Securities have been
established in conformity with the provisions of this Indenture; and

                           (iii)    that such Securities, when authenticated and
delivered by the Trustee and issued by the Company in the manner and subject to
any conditions specified in such Opinion of Counsel, will constitute valid and
legally binding obligations of the Company enforceable in accordance with their
terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar laws of general applicability relating to or affecting
creditors' rights and to general equity principles.

                  (e)      The Trustee shall initially act as authenticating
agent and may subsequently appoint another Person reasonably acceptable to the
Company as authenticating agent to authenticate Securities. Unless limited by
the terms of such appointment, an authenticating agent may authenticate
Securities whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with the Company or
an Affiliate of the Company. Provided that the authentication agent has entered
into an agreement with the Company concerning the authentication agent's duties,
the Trustee shall not be liable for any act

                                       10

<PAGE>

or any failure of the authenticating agent to perform any duty either required
herein or authorized herein to be performed by such Person in accordance with
this Indenture.

                  (f)      The Trustee shall have the right to decline to
authenticate and deliver any Securities under this Section 2.3 if the Trustee
determines that such action may not lawfully be taken or if the Trustee in good
faith shall determine that such action would expose the Trustee to personal
liability to existing Holders or would affect the Trustee's own rights, duties
or immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

                  (g)      The Securities shall be issued only in registered
form without coupons.

SECTION 2.4       REGISTRAR AND PAYING AGENT.

                  (a)      The Company shall maintain an office or agency where
Securities may be presented for registration of transfer or for exchange
("Registrar") and an office or agency where Securities may be presented for
payment ("Paying Agent"). The Registrar shall keep a register of the Securities
and of their transfer and exchange. The Company may appoint one or more
co-registrars and one or more additional paying agents. The term "Paying Agent"
includes any additional paying agent and the term "Registrar" includes any
co-registrar, provided that there shall only be one register for each Series of
Securities. So long as a Series of Securities is listed or quoted on a stock
exchange or securities association, the Company shall maintain a co-registrar
and a co-paying agent in such other locations, if any, as such stock exchange or
securities association shall require.

                  (b)      The Company shall enter into an appropriate agency
agreement with any Registrar or Paying Agent not a party to this Indenture. The
agreement shall implement the provisions of this Indenture that relate to such
agent. The Company shall promptly notify the Trustee of the name and address of
any such agent and any change in the address of such agent. If the Company fails
to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall
be entitled to appropriate compensation therefor pursuant to Section 6.7. The
Company or any Subsidiary or Affiliate of the Company may act as Paying Agent,
Registrar or transfer agent.

                  (c)      The Company initially appoints the Trustee as
Registrar and Paying Agent in connection with the Securities.

SECTION 2.5       PAYING AGENT TO HOLD MONEY IN TRUST.

                  On or prior to 11:00 a.m., New York City time, on each due
date of the principal and interest on any Security, the Company shall deposit
with the Paying Agent a sum of money denominated in the currency of such
payment, in immediately available funds, sufficient to pay such principal and
interest in funds available when such becomes due. The Company shall require
each Paying Agent (other than the Trustee) to agree in writing that the Paying
Agent shall hold in trust for the benefit of Securityholders or the Trustee all
money held by the Paying Agent for the payment of principal of or interest on
the Securities (whether such money has been paid to it by the Company or any
other obligor on the Securities) and shall notify the Trustee of any default by
the Company (or any other obligor on the Securities) in making any such payment.
If the Company or a Subsidiary or an Affiliate of the Company acts as Paying
Agent, it shall

                                       11

<PAGE>

segregate the money held by it as Paying Agent and hold it as a separate trust
fund for the benefit of the Securityholders. If the Company defaults in its
obligation to deposit funds for the payment of principal and interest the
Trustee may, during the continuation of such default, require a Paying Agent to
pay all money held by it to the Trustee. The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee and to account for any
funds disbursed by it. Upon doing so, the Paying Agent (other than the Company
or a Subsidiary or Affiliate of the Company) shall have no further liability for
the money delivered to the Trustee.

SECTION 2.6       SECURITYHOLDER LISTS.

                  The Trustee shall preserve in as current a form as reasonably
practicable the most recent list available to it of the names and addresses of
Securityholders. If the Trustee is not the Registrar, the Company shall furnish
to the Trustee at least seven Business Days before each Interest Payment Date
and at such other times as the Trustee may request in writing a list in such
form and as of such date as the Trustee may reasonably require of the names and
addresses of the Securityholders, and the Company shall otherwise comply with
TIA Section 312(a).

SECTION 2.7       TRANSFER AND EXCHANGE.

                  (a)      The Securities shall be transferable only upon the
surrender of a Security to the Registrar for registration of transfer. When a
Security is presented to the Registrar with a request to register a transfer,
the Registrar shall register the transfer as requested if the requirements of
Section 8-401(a) of the Uniform Commercial Code are met (and the Registrar shall
be entitled to assume such requirements have been met unless it receives written
notice to the contrary) and, if so required by the Trustee or the Company, if
the Security presented is accompanied by a written instrument of transfer in
form satisfactory to the Trustee and the Company, duly executed by the
registered owner or by his or her attorney duly authorized in writing, in which
case, the Registrar shall deliver, to or at the direction of such registered
owner, one or more new Securities of the same Series, of any authorized
denominations and of a like aggregate principal amount. When Securities are
presented to the Registrar with a written request to exchange them for an equal
principal amount of Securities of the same Series and of other authorized
denominations, the Registrar shall make the exchange as requested if the same
requirements are met. To permit registration of transfers and exchanges, the
Company shall execute a written order signed by two Officers ordering
authentication and the Trustee, upon receipt of such order, shall authenticate
Securities at the Registrar's request. The Depository shall, by acceptance of a
Global Security, agree that transfers of beneficial interests in such Global
Security may be effected only (i) in accordance with this Indenture and the
Securities represented by such Global Security and (ii) through a book-entry
system maintained by the Depository (or its agent), and that ownership of a
beneficial interest in the Global Security shall be required to be reflected in
a book entry.

                  (b)      No service charge shall be made for any registration
of transfer or exchange of the Securities, but the Company may require payment
of a sum sufficient to cover any transfer tax or similar governmental charge
payable in connection therewith (other than any such transfer taxes or similar
governmental charge payable upon exchange pursuant to Section 2.11, 8.5 or 9.6).

                                       12

                  (c)      Prior to the due presentation for registration of
transfer of any Security, the Company, the Trustee, the Paying Agent or the
Registrar may deem and treat the person in whose name a Security is registered
as the absolute owner of such Security for the purpose of receiving payment of
principal of and interest (subject to the record date provisions thereof) on
such Security and for all other purposes whatsoever, whether or not such
Security is overdue, and none of the Company, the Trustee, the Paying Agent or
the Registrar shall be affected by notice to the contrary.

                  (d)      Notwithstanding any other provisions of this Section
2.7, unless and until it is exchanged in whole or in part for Securities of any
Series in definitive registered form, a Global Security representing all or a
portion of the Securities of a Series may not be transferred except as a whole
by the Depository to a nominee of such Depository or by a nominee of such
Depository to such Depository or another nominee of such Depository or by such
Depository or any such nominee to a successor Depository or a nominee of such
successor Depository.

                  (e)      If the Depository notifies the Company that it is
unwilling or unable to continue as Depository for the Global Securities of any
Series or if at any time the Depository shall no longer be eligible under the
next sentence of this paragraph (e), the Company shall appoint a successor
Depository with respect to such Securities. Each Depository appointed pursuant
to this Section 2.7 must, at the time of its appointment and at all times while
it serves as Depository, be a clearing agency registered under the Exchange Act
and any other applicable statute or regulation. The Company will execute a
written order of the Company signed by two Officers ordering authentication, and
the Trustee will authenticate and deliver, upon receipt of such order,
Securities in definitive registered form without coupons in any authorized
denominations representing Securities of a Series in exchange for such Global
Security or Securities of such Series if (i) the Depository notifies the Company
that it is unwilling or unable to continue as Depository for the Global
Securities of such Series or if at any time the Depository shall no longer be
eligible to serve as Depository and a successor Depository for the Securities of
such Series is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such ineligibility or (ii) an Event of
Default with respect to the Securities of such Series has occurred and is
continuing.

                  (f)      The Company may at any time and in its sole
discretion determine that the Securities of a Series shall no longer be
represented by a Global Security or Securities. In such event the Company will
execute a written order signed by two Officers ordering authentication, and the
Trustee will authenticate and deliver, upon receipt of such order, Securities of
such Series in definitive registered form without coupons in any authorized
denominations representing such Securities in exchange for such Global Security
or Securities.

                  (g)      Upon the exchange of a Global Security for Securities
in definitive registered form without coupons pursuant to either of paragraphs
(e) or (f) above, in authorized denominations, such Global Security shall be
cancelled by the Trustee. Securities in definitive registered form issued in
exchange for a Global Security pursuant to this Section 2.7 shall be registered
in such names and in such authorized denominations as the Depository for such
Global Security, pursuant to written instructions from its direct or indirect
participants, shall instruct the Trustee. The Trustee shall deliver such
Securities to or as directed by the Persons in whose names such Securities are
so registered.

                                       13

<PAGE>

                  (h)      No holder of a beneficial interest in any Global
Security held on its behalf by a Depository shall have any rights under this
Indenture with respect to such Global Security, and such Depository may be
treated by the Company, the Trustee, and any agent of the Company or the Trustee
as the owner of such Global Security for all purposes whatsoever. None of the
Company, the Trustee or any agent of the Company or the Trustee will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests of a Global Security
or maintaining, supervising or reviewing any records relating to such beneficial
ownership interests. 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 a
Depository or impair, as between a Depository and such holders of beneficial
interests, the operation of customary practices governing the exercise of the
rights of the Depository (or its nominee) as Holder of any Security.

                  (i)      The Company shall not be required (i) to issue,
register the transfer of or exchange any Securities of a Series during a period
beginning at the opening of business 15 days before the day of the mailing of a
notice of redemption of any such Securities selected for redemption under
Section 9.3 and ending at the close of business on the day of such mailing or
(ii) to register the transfer of or exchange any Security so selected for
redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part.

                  (j)      All Securities issued upon any transfer or exchange
pursuant to the terms of this Indenture will evidence the same debt and will be
entitled to the same benefits under this Indenture as the Securities surrendered
upon such transfer or exchange.

SECTION 2.8       REPLACEMENT SECURITIES.

                  (a)      If a mutilated Security is surrendered to the
Registrar or if the Holder of a Security claims that the Security has been lost,
destroyed or wrongfully taken and the Holder furnishes to the Company and the
Trustee evidence to their satisfaction of such loss, destruction or wrongful
taking, the Company shall issue a written order signed by two Officers ordering
authentication and the Trustee shall, in the absence of notice to the Company or
the Trustee that such Security has been acquired by a bona fide purchaser and
upon receipt of such order, authenticate a replacement Security of the same
Series if the requirements of this Indenture and of Section 8-405 of the Uniform
Commercial Code are met (and the Registrar and the Trustee shall be entitled to
assume such requirements have been met unless each of them receives written
notice to the contrary) and if there is delivered to the Company and the Trustee
such security or indemnity as may be required to save each of them harmless,
satisfactory to the Company and the Trustee. The Company and the Trustee may
charge the Holder, and the Holder shall pay as a condition to such issuance and
authentication, for their expenses in replacing a Security.

                  (b)      In case any such mutilated, lost, destroyed or
wrongfully taken 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)      Every replacement Security of each Series is an
additional obligation of the Company and shall be entitled to the benefits of
this Indenture.

                                       14

<PAGE>

                  (d)      The provisions of this Section 2.8 are exclusive and
shall preclude (to the extent lawful) all other rights and remedies with respect
to the replacement or payment of mutilated, lost, destroyed or wrongfully taken
Securities.

SECTION 2.9       OUTSTANDING SECURITIES.

                  (a)      The Securities of each Series outstanding at any time
are all the Securities authenticated by the Trustee except for those canceled by
it, those delivered to it for cancellation, and those described in this Section
2.9 as not outstanding.

                  (b)      If a Security is replaced or paid pursuant to Section
2.8, it ceases to be outstanding unless the Trustee and the Company receive
proof satisfactory to each of them that the replaced or paid Security is held by
a bona fide purchaser.

                  (c)      If all the principal and interest on any Securities
of any Series are considered paid under Section 3.1, the Securities of such
Series cease to be outstanding under this Indenture and interest on the
Securities of such Series shall cease to accrue.

                  (d)      If the Paying Agent (other than the Company or a
Subsidiary or an Affiliate of the Company) holds in accordance with this
Indenture on a maturity or redemption date money sufficient to pay all principal
and interest due on that date with respect to Securities of any Series then on
and after that date such Securities cease to be outstanding and interest on them
ceases to accrue (unless there shall be a default in such payment).

                  (e)      Subject to Section 2.10, a Security does not cease to
be outstanding because the Company or an Affiliate thereof holds the Security.

SECTION 2.10      DETERMINATION OF HOLDERS' ACTION.

                  In determining whether the Holders of the required principal
amount of any Series of Securities have concurred in any direction, amendment,
waiver or consent, Securities owned by or pledged to the Company, any other
obligor upon the Securities or any Affiliate of the Company or such other
obligor shall be disregarded and deemed not to be outstanding, except that for
the purposes of determining whether the Trustee shall be protected in relying on
any such direction, waiver or consent, only Securities which the Trustee knows
are so owned or pledged shall be so disregarded.

SECTION 2.11      TEMPORARY SECURITIES.

                  Until definitive Securities of any Series are ready for
delivery, the Company may prepare a written order signed by two Officers
ordering authentication of temporary Securities and the Trustee, upon receipt of
such order, shall authenticate temporary Securities of such Series. Temporary
Securities shall be substantially in the form of definitive Securities but may
have variations that the Company considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall prepare a written order signed by
two Officers ordering authentication of definitive Securities and the Trustee,
upon receipt of such order, shall authenticate definitive Securities in exchange
for temporary Securities. Until such exchange,

                                       15

<PAGE>

temporary Securities of any Series shall be entitled to the same rights,
benefits and privileges as definitive Securities of such Series.

SECTION 2.12      CANCELLATION.

                  The Company at any time may deliver Securities to the Trustee
for cancellation. The Registrar and Paying Agent shall forward to the Trustee
any Securities surrendered to them for registration of transfer, exchange or
payment. The Trustee, upon receipt of a written order of the Company signed by
two Officers, shall cancel all Securities surrendered for registration of
transfer, exchange, payment or cancellation and shall deliver to the Company a
certificate of cancellation. The Company may not issue new Securities to replace
Securities that it has paid or delivered to the Trustee for cancellation.

SECTION 2.13      DEFAULTED INTEREST.

                  If the Company defaults in a payment of interest on the
Securities of any Series, it shall pay Defaulted Interest, plus any interest
payable on the Defaulted Interest to the extent permitted by applicable law, in
any lawful manner. It may pay the Defaulted Interest to the Persons who are
Securityholders on a subsequent special record date which date shall be at least
five Business Days prior to the payment date. The Company shall fix the special
record date and payment date. At least 15 days before the special record date,
the Company (or the Trustee, in the name of and at the expense of and at the
written direction of the Company) shall mail to Securityholders a notice that
states the special record date, payment date and amount of interest to be paid.

                              ARTICLE 3 - COVENANTS

SECTION 3.1       PAYMENT OF SECURITIES.

                  The Company shall pay the principal of and interest on the
Securities of each Series on the dates and in the manner provided in such
Securities. The Company shall pay interest on overdue principal at the rate
borne by or provided for in such Securities; it shall pay interest on overdue
installments of interest at the rate borne by or provided for in such Securities
to the extent lawful. Principal and interest shall be considered paid on the
date due if the Trustee or the Paying Agent (other than the Company or a
Subsidiary or an Affiliate of the Company) has received from or on behalf of the
Company money sufficient to pay all principal and interest then due in
accordance with Section 2.5.

SECTION 3.2       MAINTENANCE OF OFFICE OR AGENCY.

                  The Company shall maintain in the Borough of Manhattan, the
City of New York, and, in the case of Securities listed or quoted on a stock
exchange or securities association, in such other locations, if any, as shall be
required by such stock exchange or securities association, an office or agency
where Securities may be surrendered for registration of transfer or exchange or
for presentation for payment 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 agency. If at any time the Company
shall fail to maintain any such required office or agency or

                                       16

<PAGE>

to furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the address of the Trustee set
forth in Section 10.2. The Company initially appoints the Trustee as its agency
for the foregoing purposes in the Borough of Manhattan, the City of New York.

                  The Company may also from time to time designate one or more
other offices or agencies where the Securities may be presented or surrendered
for any or all such purposes and may from time to time rescind such
designations; provided, 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 3.3       COMPLIANCE CERTIFICATE.

                  The Company shall, within 120 days after the close of each
fiscal year in which Securities are outstanding hereunder, file with the Trustee
an Officer's Certificate, provided that one Officer executing the same shall be
the principal executive officer, the principal financial officer or the
principal accounting officer of the Company, covering the period from the date
of issuance of Securities hereunder to the end of the fiscal year in which the
Securities were first issued hereunder, in the case of the first such
certificate, and covering the preceding fiscal year in the case of each
subsequent certificate, and stating whether or not, to the knowledge of each
such executing Officer, the Company has complied with and performed and
fulfilled all covenants on its part contained in this Indenture and is not in
Default in the performance or observance of any of the terms or provisions
contained in this Indenture, and, if any such signer has obtained knowledge of
any Default by the Company in the performance, observance or fulfillment of any
such covenant, term or provision specifying each such Default and the nature
thereof. For the purpose of this Section 3.3, compliance shall be determined
without regard to any grace period or requirement of notice provided pursuant to
the terms of this Indenture.

SECTION 3.4       SEC REPORTS.

                  (a)      The Company shall, to the extent required by TIA
Section 314(a), file with the Trustee, within 15 days after the filing with the
SEC, copies of the annual reports and of the information, documents and other
reports (or copies of such portions of any of the foregoing as the SEC may by
rules and regulations prescribe) which the Company is required to file with the
SEC pursuant to Section 13 or 15(d) of the Exchange Act. In the event the
Company is at any time no longer subject to the reporting requirements of
Section 13 or 15(d) of the Exchange Act, it shall, for so long as the Securities
remain outstanding, file with the Trustee, within 15 days after the Company
would have been required to file such documents with the SEC, copies of the
annual reports and of the information, documents and other reports which the
Company would have been required to file with the SEC if the Company had
continued to be subject to such Sections 13 or 15(d). The Company also shall
comply with the other provisions of TIA Section 314(a).

                  (b)      Delivery of such reports, information and documents
to the Trustee is for informational purposes only and the Trustee's receipt of
such shall not constitute constructive

                                       17

<PAGE>

notice of any information contained therein or determinable from information
contained therein, including the Company's compliance with any of its covenants
hereunder (as to which the Trustee is entitled to rely exclusively on an
Officers' Certificates).

SECTION 3.5       FURTHER INSTRUMENTS AND ACTS.

                  The Company (upon the reasonable request of the Trustee) will
execute and deliver such further instruments and do such further acts as may be
reasonably necessary or proper to enable the Trustee to exercise and enforce its
rights under this Indenture and to carry out more effectively the purpose of
this Indenture.

consolidation or into which the Company is merged or to which the properties and
assets of the Company are sold, assigned, conveyed, transferred, disposed of or
leased as aforesaid (the "Successor Corporation") shall be a corporation
organized and existing under the laws of the United States or any State thereof
or the District of Columbia and shall expressly assume, by an indenture
supplemental hereto, executed and delivered to the Trustee, in form reasonably
satisfactory to the Trustee, all the obligations of the Company under this
Indenture and each Series of Securities;

                           (ii)     immediately after giving effect to such
transaction, no Default shall have occurred and be continuing;

                           (iii)    the Company shall have delivered, or caused
to be delivered, to the Trustee an Officers' Certificate and, as to legal
matters, an Opinion of Counsel (which may rely upon an Officers' Certificate as
to factual matters), each in form reasonably satisfactory to the Trustee, each
stating that such consolidation, merger, sale, assignment, conveyance, transfer,
disposition or lease and such supplemental indenture comply with this Indenture
and that all conditions precedent herein provided for relating to such

                  (b)      Notwithstanding the foregoing paragraph (a)(ii), the
Company or any Subsidiary may consolidate with or merge into the Company or any

(a)(iii) are satisfied in connection therewith.

SECTION 4.2       SUCCESSOR SUBSTITUTED.

                  (a)      Upon any such consolidation or merger, or any sale,

all of the properties or assets of

                                       18

<PAGE>

the Company in accordance with Section 4.1, the Successor Corporation shall
succeed to and be substituted for the Company under this Indenture and each
Series of Securities, and the Company shall (except in the case of a lease)

                       ARTICLE 5 - DEFAULTS AND REMEDIES

SECTION 5.1       EVENTS OF DEFAULT.

                  An "Event of Default" means, with respect to any Series of
Securities, any of the following events:

                  (a)      default in the payment of interest on any Security of

by Holders of at least 25% in principal amount of the Securities of such Series
then outstanding hereunder;

                  (d)      there shall have occurred either (i) a default by the
Company or any Significant Subsidiary under any instrument or instruments under
which there is or may be secured or evidenced any Indebtedness of the Company or
any Significant Subsidiary of the Company (other than the Securities of such
Series) having an outstanding principal amount of $20,000,000.00 (or its foreign
currency equivalent) or more individually or in the aggregate that has caused
the holders thereof to declare such Indebtedness to be due and payable prior to
its Stated Maturity, unless such declaration has been rescinded within 30
Business Days or (ii) a default by the Company or any Significant Subsidiary in
the payment when due of any portion of the principal under any such instrument
or instruments, and such unpaid portion exceeds $20,000,000.00 (or its foreign
currency equivalent) individually or in the aggregate and is not paid, or such
default is not cured or waived, within any grace period applicable thereto,
unless such Indebtedness is discharged within 30 Business Days of the Company or
a Significant Subsidiary becoming aware of such default;

                  (e)      the Company or any Significant Subsidiary pursuant to
or within the meaning of any Bankruptcy Law:

                           (i)      commences a voluntary case;

                                       19

<PAGE>

                           (ii)     consents to the entry of an order for relief
against it in an involuntary case;

                           (iii)    consents to the appointment of a Custodian
of it or for all or substantially all of its property;

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

                           (v)      admits in writing its inability to generally
pay its debts as such debts become due; or

                           (vi)     takes any comparable action under any
foreign laws relating to insolvency;

                  (f)      a court of competent jurisdiction enters an order or
decree under any Bankruptcy Law that:

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

                           (ii)     appoints a Custodian of the Company or any
Significant Subsidiary or for all or substantially all of its property; or

                           (iii)    orders the winding up or liquidation of the
Company or any Significant Subsidiary;

or any similar relief is granted under any foreign laws; and the order or decree
remains unstayed and in effect for 60 days.

Any notice of Default given by the Trustee or Securityholders under this Section
5.1 must specify the Default, demand that it be remedied and state that the
notice is a "Notice of Default." The Company shall deliver to the Trustee,
within 30 days after the occurrence thereof, written notice of any event which
with the giving of notice or the lapse of time or both would become an Event of
Default under clause (d), (e) or (f) hereof. Subject to the provisions of
Section 6.1 and 6.2, the Trustee shall not be deemed to have notice or be
charged with knowledge of any Default or Event of Default unless written notice
thereof shall have been given to the Trustee in accordance with Section 10.2 by
the Company, the Paying Agent, any Holder or an agent of any Holder and such
notice references the Securities and this Indenture.

SECTION 5.2       ACCELERATION.

                  If an Event of Default (other than an Event of Default
specified in clause (e) and (f) of Section 5.1 with respect to the Company)
occurs and is continuing with respect to the Securities of any Series, the
Trustee by notice to the Company, or the Holders of at least 25% in principal
amount of the Securities of such Series by notice to the Company and the
Trustee, may declare the principal of and accrued and unpaid interest on all the
Securities of such Series to be due and payable. Upon such declaration the
principal and interest shall be due and payable immediately. If an Event of
Default specified in clause (e) or (f) of Section 5.1 with respect to

                                       20

<PAGE>

the Company occurs, the principal of and interest on all the Securities of each
Series shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Securityholders. If
all existing Events of Default with respect to such Series have been cured or
waived (except nonpayment of principal or interest that has become due solely
because of the acceleration), the acceleration and its consequences in respect
of a Series of Securities shall be automatically annulled and rescinded;
provided, that such annulment and rescission would not conflict with any
judgment or decree. No such rescission shall affect any subsequent or other
Default or Event of Default or impair any consequent right.

SECTION 5.3       OTHER REMEDIES.

                  (a)      If an Event of Default occurs and is continuing, the
Trustee may pursue any available remedy to collect the payment of principal or
interest on the relevant Securities or to enforce the performance of any
provision of such Securities or this Indenture.

                  (b)      The Trustee may maintain a proceeding even if it does
not possess any of the Securities or does not produce any of them in the
proceeding. A delay or omission by the Trustee or any Securityholder in
exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of or acquiescence in the
Event of Default. All remedies are cumulative to the extent permitted by
applicable law.

SECTION 5.4       WAIVER OF PAST DEFAULTS.

                  The Holders of a majority in principal amount of a Series of
Securities by written notice to the Trustee may waive an existing Default and
its consequences with respect to such Series, except (a) a Default in the
payment of the principal of or interest on any Security of such Series or (b) a
Default in respect of a provision that under Section 8.2 cannot be amended
without the consent of each affected Securityholder of such Series. When a
Default is waived, it is deemed cured, but no such waiver shall extend to any
subsequent or other Default or Event of Default or impair any consequent right.

SECTION 5.5       CONTROL BY MAJORITY.

                  The Holders of a majority in principal amount of the
Securities of a Series may 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 it with respect to such Series. However, the Trustee may
refuse to follow any direction that conflicts with applicable law or this
Indenture, or, subject to Section 6.1, that the Trustee determines is unduly
prejudicial to the rights of other Securityholders, or would involve the Trustee
in personal liability; provided, that the Trustee may take any other action
deemed proper by the Trustee that is not inconsistent with such direction. Prior
to taking any action hereunder, the Trustee shall be entitled to indemnification
from Securityholders of such Series satisfactory to it in its sole discretion
against all risk, losses and expenses caused by taking or not taking such
action. Subject to Section 6.1, 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 the Securityholders pursuant to this Indenture, unless
such Securityholders shall have provided to the Trustee security or indemnity
reasonably satisfactory to it against the

                                       21

<PAGE>

costs, expenses and liabilities which might be incurred in compliance with such
request or direction.

SECTION 5.6       LIMITATION ON SUITS.

                  A Securityholder of a Series may pursue a remedy with respect
to this Indenture or the Securities of such Series only if:

                  (a)      the Holder gives to the Trustee written notice of a
continuing Event of Default with respect to that Series;

                  (b)      the Holders of at least 25% in principal amount of
the Securities of such Series make a written request to the Trustee to pursue
the remedy;

                  (c)      such Holder or Holders offer to the Trustee security
or indemnity reasonably satisfactory to it against any loss, liability or
expense;

                  (d)      the Trustee does not comply with the request within
60 days after receipt of the notice, request and the offer of security or
indemnity; and

                  (e)      the Holders of a majority in principal amount of the
Securities of such Series do not give the Trustee a direction inconsistent with
the request during such 60 day period.

A Securityholder may not use this Indenture to prejudice the rights of another
Securityholder or to obtain a preference or priority over another
Securityholder.

SECTION 5.7       RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

                  Notwithstanding any other provision of this Indenture, the
right of any Holder of a Security to receive payment of principal and interest
on the Security, on or after the respective due dates expressed or provided for
in the Security, or to bring suit for the enforcement of any such payment on or
after such respective dates, shall not be impaired or affected without the
consent of the Holder.

SECTION 5.8       COLLECTION SUIT BY TRUSTEE.

                  If an Event of Default specified in Section 5.1(a) or (b)
occurs and is continuing with respect to a Security, the Trustee may recover
judgment in its own name and as trustee of an express trust against the Company
or any other obligor on such Security for the whole amount of principal and
interest remaining unpaid (together with interest on such unpaid interest to the
extent lawful) and the amounts provided for in Section 6.7.

SECTION 5.9       TRUSTEE MAY FILE PROOFS OF CLAIM.

                  (a)      The Trustee may file such proofs of claim and other
papers or documents and take such other actions including participating as a
member or otherwise in any committees of creditors appointed in the matter as
may be necessary or advisable in order to have the claims

                                       22

<PAGE>

of the Trustee (including any claim for the amounts provided in Section 6.7) and
the Securityholders allowed in any judicial proceedings relative to the Company,
its creditors or its property and, unless prohibited by applicable law or
regulations, may vote on behalf of the Holders of each Series in any election of
a trustee in bankruptcy or other Person performing similar functions, and any
Custodian in any such judicial proceeding is hereby authorized by each Holder to
make 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 its counsel, and any other amounts due
the Trustee under Section 6.7. To the extent that the payment of any such amount
due to the Trustee under Section 6.7 out of the estate in any such proceeding
shall be denied for any reason, payment of the same shall be secured by a Lien
on, and shall be paid out of, any and all distributions, dividends, money,
securities and other properties which the Holders of the Securities may be
entitled to receive in such proceeding whether in liquidation or under any plan
of reorganization or arrangement or otherwise.

                  (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;
provided, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors'
or other similar committee.

SECTION 5.10      PRIORITIES.

                  If the Trustee collects any money or other consideration
pursuant to this Article 5, it shall pay out the money or other consideration in
the following order:

                  (a)      First: to the Trustee, its attorneys and agents, for
all amounts due under Section 6.7;

                  (b)      Second: to Securityholders for amounts due and unpaid
on the Securities of the relevant Series for principal and interest, ratably,
without preference or priority of any kind, according to the amounts due and
payable on the Securities of such Series for principal and interest,
respectively; and

                  (c)      Third: to the Company (or to such other party as a
court of competent jurisdiction directs).

The Trustee may fix a record date and payment date for any payment to
Securityholders of such Series pursuant to this Section 5.10. At least 15 days
before such record date, the Company shall give written notice to each
Securityholder of such Series and the Trustee of the record date, the payment
date and amount to be paid.

SECTION 5.11      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 or
omitted by it as Trustee, a court in its

                                       23

<PAGE>

discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorneys' fees, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section 5.11 does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 5.7, or a suit
by Holders of more than 10% in principal amount of the Securities of any Series.

SECTION 5.12      WAIVER OF STAY OR EXTENSION LAWS.

                  The Company shall 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
hereby expressly waives all benefit or advantage of any such law, and shall not
hinder, delay or impede the execution of any power herein granted to the
Trustee, but shall suffer and permit the execution of every such power as though
no such law had been enacted.

                              ARTICLE 6 - TRUSTEE

SECTION 6.1       DUTIES OF TRUSTEE.

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

                  (b)      Except during the continuance of an Event of Default:

                           (i)      The duties of the Trustee shall be

                           (ii)     In the absence of bad faith on its part, the
Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions
furnished to the Trustee and conforming to the requirements of this Indenture.
However, the Trustee shall examine the certificates and opinions to determine
whether or not they conform to the requirements of this Indenture (but need not
confirm or investigate the accuracy of mathematical calculations or other facts
stated therein).

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

                           (i)      This paragraph (c) does not limit the effect
of paragraph (b) of this Section 6.1.

                                       24

<PAGE>

                           (ii)     The Trustee shall not be liable for any

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, unless it receives indemnity satisfactory to it
against any risk, loss, liability or expense.

                  (d)      Every provision of this Indenture that in any way
relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section
6.1.

                  (e)      The Trustee, in its capacity as Trustee and Registrar
and Paying Agent, shall not be liable to the Company, the Securityholders or any
other Person for interest on any money received by it, including money with
respect to principal of or interest on the Securities of any Series, except as
the Trustee may agree with the Company.

                  (f)      The Trustee shall not be liable for interest on any
money received by it except as the Trustee may agree in writing with the

                  (a)      The Trustee may rely on any document reasonably
believed by it to be genuine and to have been signed or presented by the proper
Person. The Trustee need not investigate any fact or matter stated in the
document.

                  (b)      Before the Trustee acts or refrains from acting, it
may require an Officers' Certificate, an Opinion of Counsel (which may rely upon
an Officers' Certificate as to factual matters) or both covering such matters as
it shall reasonably determine. The Trustee shall not be liable for any action it
takes or omits to take in good faith in reliance on any such Officers'
Certificate or Opinion of Counsel.

                  (c)      The Trustee may act through agents and shall not be
responsible for the misconduct or negligence of any agent appointed with due
care by it hereunder.

                  (d)      The Trustee shall not be liable for any action it
takes or omits to take in good faith which it believes to be authorized or
within its rights or powers; provided, that the Trustee's conduct does not
constitute willful misconduct, negligence or bad faith.

                  (e)      The Trustee may consult with counsel of its
selection, and the advice or opinion of such counsel as to matters of applicable
law shall be full and complete authorization and protection from liability in

                                       25

<PAGE>

                  (f)      The Trustee shall not be obligated to make any

statement, instrument, opinion, report, notice, request, direction, consent,
order, bond, debenture or any other paper or document.

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

                  (h)      The rights, privileges, protections, immunities and
benefits given to the Trustee, including its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities
hereunder, and to each agent, custodian and other Person employed to act
hereunder.

                  (i)      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 6.2 and to the provisions of
Section 315 of the TIA.

SECTION 6.3       INDIVIDUAL RIGHTS OF TRUSTEE.

                  The Trustee in its individual or any other capacity may become
the owner or pledgee of Securities and may otherwise deal with the Company or an
Affiliate with the same rights it would have if it were not Trustee. Any Agent
may do the same with like rights. However, the Trustee is subject to Sections
6.10 and 6.11.

SECTION 6.4       TRUSTEE'S DISCLAIMER.

                  The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture or the
Securities of any Series, it shall not be accountable for the Company's use of
the proceeds from the Securities of any Series or any money paid to the Company
or upon the Company's direction under any provision of this Indenture, it shall
not be responsible for the use or application of any money received by any
Paying Agent (except for any use or application caused by the gross negligence
or willful misconduct of the Trustee), and it shall not be responsible for any
recital or statement in this Indenture or the Securities of any Series other
than its authentication. The Trustee shall have no duty to ascertain or inquire
as to the performance of the Company's covenants in Article 3 hereof.

SECTION 6.5       NOTICE OF DEFAULTS.

                  If a Default or an Event of Default occurs and is continuing
and if it is actually known to a Trust Officer of the Trustee, the Trustee shall
mail to Securityholders of the affected Series a notice of the Default or Event
of Default within 90 days after a Trust Officer of the Trustee has actual
knowledge of the occurrence thereof. Except in the case of a Default in any
payment on any Security, the Trustee may withhold the notice if and so long as a
committee of its Trust Officers in good faith determines that withholding the
notice is in the interests of Securityholders of the affected Series.

                                       26

SECTION 6.6       REPORTS BY TRUSTEE TO HOLDERS.

                  (a)      Within 60 days after the first July 15 following the
first issuance of Securities hereunder and for so long as Securities are
outstanding hereunder, the Trustee shall mail to Securityholders a brief report
dated as of such date that complies with TIA Section 313(a) if required by that
section. The Trustee also shall comply with TIA Section 313(b)(2).

                  (b)      A copy of each report at the time of its mailing to
Securityholders shall be filed with the SEC and each stock exchange or
securities association on which Securities are listed or quoted. The Company
shall promptly notify the Trustee when Securities are listed or quoted on any
stock exchange or securities association and of any delisting thereof.

SECTION 6.7       COMPENSATION AND INDEMNITY.

                  (a)      The Company shall pay to the Trustee from time to
time such compensation for its services as the parties shall agree. The
Trustee's compensation shall not be limited by any applicable law on
compensation of a trustee of an express trust. In addition to compensation for
its services, the Company shall reimburse the Trustee upon request for all
reasonable out-of-pocket disbursements, expenses and advances incurred by it.
Such expenses shall include the reasonable compensation and out-of-pocket
disbursements and expenses of the Trustee's agents, counsel and other
professionals.

                  (b)      The Company shall indemnify the Trustee for, and hold
it harmless against, any loss, liability, claim or expense, including reasonable
attorneys' fees, disbursements and expenses, incurred by it arising out of or in
connection with the acceptance or administration of this trust and the
performance of its duties hereunder including the costs and expenses of
defending itself against any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder. The Trustee shall
notify the Company promptly of any claim for which it may seek indemnity.
Failure by the Trustee to so notify the Company shall not relieve the Company of
its obligations hereunder. The Company shall defend the claim and the Trustee
shall cooperate in the defense. The Trustee may have separate counsel and the
Company shall pay the reasonable fees and expenses of such counsel. The Company
need not pay for any settlement made without its consent, which consent shall
not be unreasonably withheld.

                  (c)      The Company need not reimburse any expense or
indemnify against any loss or liability incurred by the Trustee through the
Trustee's own negligence or bad faith.

                  (d)      To secure the Company's payment obligations in this
Section 6.7, the Trustee shall have a Lien prior to the Holders of Securities on
all money or property held or collected by the Trustee, except that held in
trust to pay principal and interest on particular Securities of any Series.

                  (e)      Without prejudice to any other rights available to
the Trustee under applicable law, when the Trustee incurs expenses or renders
services after an Event of Default specified in Section 5.1(e) or (f) occurs,
the expenses and the compensation for the services (including the reasonable
fees and expenses of its agents and counsel) are intended to constitute expenses
of administration under any Bankruptcy Law.

                                       27

<PAGE>

                  (f)      The Company's obligations under this Section 6.7 and
any Lien arising hereunder shall survive the resignation or removal of the
Trustee, the discharge of the Company's obligations pursuant to Article 7 of
this Indenture and the termination of this Indenture.

                  (g)      When the Trustee incurs expenses or renders services
following the occurrence of an Event of Default specified in Section 5.1(e), the
Trustee's claim for expenses (including the reasonable fees and expenses of its
agents and counsel) and the compensation for the services shall be preferred
over the status of any claim of the Holders in a proceeding under any Bankruptcy
Law, and such expenses and compensation for services are intended to constitute
expenses of administration under any Bankruptcy Law. The Company's obligations
under this Section 6.7 and any claim arising hereunder shall survive the
resignation or removal of any Trustee, the discharge of the Company's
obligations pursuant to Article 9 and any rejection or termination under any
Bankruptcy Law.

SECTION 6.8       REPLACEMENT OF TRUSTEE.

                  (a)      A resignation or removal of the Trustee and
appointment of a successor Trustee shall become effective only upon the
successor Trustee's acceptance of appointment as provided in this Section 6.8.

                  (b)      The Trustee may resign at any time with respect to
any Series of Securities by so notifying the Company in writing. Provided that
no Event of Default has occurred and is continuing, the Company may remove the
Trustee with respect to any Series of Securities at any time by so notifying in
writing the Trustee of such Series of Securities. The Holders of a majority in
principal amount of the Securities of any Series may, by written notice to the
Trustee, remove the Trustee as Trustee with respect to that Series of Securities
by so notifying the Trustee and the Company. The Company, by notice to such
Trustee, shall remove such Trustee if:

                           (i)      such Trustee fails to comply with Section
6.10;

                           (ii)     such Trustee is adjudged a bankrupt or an
insolvent;

                           (iii)    a receiver or public officer takes charge of
such Trustee or its property; or

                           (iv)     such Trustee becomes incapable of acting.

                  (c)      If the Trustee resigns or is removed or becomes
incapable of acting or if a vacancy exists in the office of Trustee for any
reason with respect to one or more Series of Securities, the Company by Board
Resolution shall promptly appoint a successor Trustee or Trustees with respect
to such Series of Securities (it being understood that any such successor
Trustee may be appointed with respect to one or more or all Series of Securities
and at any time there shall be only one Trustee with respect to any particular
Series of Securities). Within one year after the successor Trustee of a Series
of Securities takes office, the Holders of a majority in principal amount of
such Securities of the affected Series may appoint a successor Trustee of such
Series to replace the successor Trustee of such Series appointed by the Company.

                                       28

<PAGE>

                  (d)      If a successor Trustee for a particular Series of
Securities does not take office within 60 days after the retiring Trustee of
such Series resigns or is removed, the retiring Trustee of such Series, the
Company or the Holders of at least 10% in principal amount of the Securities of
the affected Series may petition any court of competent jurisdiction for the
appointment of a successor Trustee for such Series.

                  (e)      If the Trustee for a particular Series of Securities
fails to comply with Section 6.10, any Securityholder who has been a bona fide
Holder of a Security for at least six months may petition any court of competent
jurisdiction for the removal of the Trustee of such Series and the appointment
of a successor Trustee of such Series. The Company shall give notice of each
resignation and each removal of the Trustee with respect to the Securities of
any Series and each appointment of a successor Trustee with respect to the
Securities of any Series by mailing written notice of such event by first-class
mail, postage prepaid, to all Holders of Securities of such Series as their
names and addresses appear in the Security Register. Each notice shall include
the name of the successor Trustee with respect to the Securities of such Series
and the address of its corporate trust office.

                  (f)      A successor Trustee of all Securities shall execute,
acknowledge and deliver a written acceptance of its appointment to the retiring
Trustee and to the Company. Thereupon the resignation or removal of the retiring
Trustee shall become effective, and such successor Trustee shall have all the
rights, powers and duties of the retiring Trustee under this Indenture. Provided
that all sums owing to the retiring Trustee have been indefeasibly paid in full,
the retiring Trustee shall promptly transfer all property held by it as Trustee
to the successor Trustee, subject to the Lien provided for in Section 6.7(d).
Notwithstanding the replacement of the Trustee pursuant to this Section 6.8, the
Company's obligations under Section 6.7 hereof shall continue for the benefit of
the retiring Trustee.

                  (g)      In case of the appointment hereunder of a successor
Trustee with respect to the Securities of one or more (but not all) Series, the
Company, the retiring Trustee and each successor Trustee with respect to the
Securities of one or more Series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (i) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, each successor Trustee all the
rights, powers and duties of the retiring Trustee with respect to the Securities
of that or those Series to which the appointment of such successor Trustee
relates, (ii) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers and duties of the retiring
Trustee with respect to the Securities of that or those Series as to which the
retiring Trustee is not retiring shall continue to be vested in the retiring
Trustee, and (iii) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental Indenture shall constitute such Trustee's
co-trustees of the same trust and that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee; and upon the execution and delivery of
such supplemental indenture the resignation or removal of the retiring Trustee
shall become effective to the extent provided therein and each such successor
Trustee, without any further action, shall become vested with all the rights,
powers and duties of the retiring Trustee with respect to the Securities of that
or those

                                       29

SECTION 7.1       DISCHARGE OF LIABILITY ON SECURITIES.

on redemption the principal of and all accrued interest on all outstanding
Securities of such Series (other than Securities replaced or paid pursuant to
Section 2.8 or Securities for whose payment money has heretofore been deposited
in trust by the Company with the Trustee or Paying Agent and thereafter repaid
to the Company as provided in the second sentence of Section 7.6), and if in
either case the Company pays all other sums payable hereunder by the Company
with respect to such Series, then, subject to Sections 7.2 and 7.7, this
Indenture shall cease to be of further effect with respect to such Series. The
Trustee shall acknowledge satisfaction and discharge of this Indenture with
respect to such Series on demand of the Company accompanied by an Officers'

Certificate as to factual matters) and at the cost and expense of the Company.

SECTION 7.2       TERMINATION OF COMPANY'S OBLIGATIONS.

                  (a)      Except as otherwise provided in this Section 7.2, the
Company may terminate its obligations under the Securities of a Series and this
Indenture with respect to such Series if:

                           (i)      the Securities of such Series mature or are
redeemable within one year,

                           (ii)     with reference to this Section 7.2, the
Company has irrevocably deposited or caused to be irrevocably deposited with the
Trustee or Paying Agent (other than the Company or a Subsidiary or Affiliate of
the Company) and conveyed all right, title and interest for the benefit of the
Holders of such Series, under the terms of an irrevocable trust agreement in
form satisfactory to the Trustee as trust funds in trust, specifically pledged
as security for, and dedicated solely to, the benefit of such Holders, in and
to, (A) money in an amount, (B) U.S. Government Obligations that, through the
payment of interest and principal in respect thereof in accordance with their
terms, will provide, not later than one Business Day before the due date of any
payment referred to in this clause (ii), money in an amount or (C) a combination
thereof in an amount sufficient, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay and discharge, without consideration of any
reinvestment of interest and after payment of all federal, state and local taxes
or other fees, charges and assessments in respect thereof payable by the Trustee
or Paying Agent, the principal of and interest on the outstanding Securities of
such Series when due; provided, that the Trustee or Paying Agent shall have been
irrevocably instructed in writing to apply such money or the proceeds of such
U.S. Government Obligations to the payment of such principal and interest with
respect to such Series;

                           (iii)    no Default with respect to such Series shall
have occurred and be continuing on the date of such deposit,

                           (iv)     such deposit will not result in or
constitute a Default or result in a breach or violation of, or constitute a
default under, any other agreement or instrument to which the Company is a party
or by which it is bound; and

                                       31

<PAGE>

                           (v)      the Company has delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel (which may rely upon an
Officers' Certificate as to factual matters), in each case stating that all
conditions precedent provided for herein relating to the satisfaction and
discharge of this Indenture with respect to such Series have been complied with;

provided, that if the Securities of the Series are to be redeemed, either the
Securities have been called for redemption or are to be called for redemption
within one year under arrangements satisfactory to the Trustee for the giving of
the notice of redemption by the Trustee in the name, and at the expense, of the
Company.

fulfillment of the other requirements of this Section 7.2, the Trustee upon
request shall acknowledge in writing the discharge of the Company's obligations

                  (a)      Unless otherwise provided with respect to a Series of
Securities in accordance with Section 2.1, the Company will be deemed to have
paid and will be discharged from any and all obligations in respect of such
Series on the 123rd day after the date of the deposit referred to in Section
7.3(b)(i), and the provisions of this Indenture will no longer be in effect with
respect to such Series, in each case subject to paragraph (d) of this Section
7.3, and the Trustee, at the reasonable request of and at the expense of the
Company, shall execute proper instruments acknowledging the same, except as to
(i) rights of registration of transfer and exchange, (ii) substitution of
apparently mutilated, defaced, destroyed, lost or stolen Securities of such
Series, (iii) rights of Holders of such Series to receive payments of principal
thereof and interest thereon, (iv) the Company's obligations under Section 3.2,
(v) the rights, obligations and immunities of the Trustee hereunder including
those arising under Section 6.7 hereof, (vi) the rights of the Holders of such
Series as beneficiaries of this Indenture with respect to the property so

effect provided that the following conditions shall have been satisfied:

                           (i)      with reference to this Section 7.3, the
Company has irrevocably deposited or caused to be irrevocably deposited with the
Trustee or Paying Agent (other than the Company or a Subsidiary or Affiliate of

payment of interest and principal in respect thereof in accordance with their
terms, will provide, not later than one Business Day before the due date of any
payment referred to in this clause (b)(i), money in an amount or (C) a
combination thereof in

                                       32

<PAGE>

an amount sufficient, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay and discharge, without consideration of any
reinvestment of interest and after payment of all federal, state and local taxes
or other fees, charges and assessments in respect thereof payable by the Trustee
or Paying Agent, the principal of and interest on the outstanding Securities of
such Series when due; provided, that the Trustee or Paying Agent shall have been
irrevocably instructed in writing to apply such money or the proceeds of such
U.S. Government Obligations to the payment of such principal and interest with
respect to such Series;

                           (ii)     such deposit will not result in or
constitute a Default or result in a breach or violation of, or constitute a
default under, any other agreement or instrument to which the Company is a party
or by which it is bound;

have occurred and be continuing on the date of such deposit or during the period
ending on the 123rd day after such date of deposit;

                           (iv)     the Company shall have delivered to the
Trustee (A) either (1) a ruling directed to the Trustee received from the
Internal Revenue Service to the effect that the Holders will not recognize
income, gain or loss for federal income tax purposes as a result of the
Company's exercise of its option under this Section 7.3 and will be subject to
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 option had not been exercised or (2)
an Opinion of Counsel (who may not be an employee of the Company) to the same
effect as the ruling described in clause (A)(1) hereof accompanied by a ruling
to that effect published by the Internal Revenue Service, unless there has been
a change in the applicable federal income tax law since the date of this
Indenture such that a ruling from the Internal Revenue Service is no longer
required and (B) an Opinion of Counsel to the effect that (1) the creation of
the defeasance trust does not violate the Investment Company Act of 1940, (2)
after the passage of 123 days following the deposit (except, with respect to any
trust funds for the account of any Holder of such Series who may be deemed to be
an "insider" for purposes of Title 11 of the United States Code, after one year
following the deposit), the trust funds will not be subject to the effect of
Section 547 of the United States Bankruptcy Code or Section 15 of the New York
Debtor and Creditor Law in a case commenced by or against the Company under
either such statute, and either (x) the trust funds will no longer remain the
property of the Company (and therefore, will not be subject to the effect of any
applicable bankruptcy, insolvency, reorganization or similar laws affecting
creditors' rights generally) or (y) if a court were to rule under any such law
in any case or proceeding that the trust funds remained property of the Company,
(I) assuming such trust funds remained in the possession of the Trustee prior to
such court ruling to the extent not paid to Holders of such Series, the Trustee
will hold, for the benefit of such Holders, a valid and perfected security
interest in such trust funds that is not avoidable in bankruptcy or otherwise
except for the effect of Section 552(b) of the United States Bankruptcy Code on
interest on the trust funds accruing after the commencement of a case under such
statute and (II) such Holders will be entitled to receive adequate protection of
their interests in such trust funds if such trust funds are used in such case or
proceeding; and

                                       33

<PAGE>

                           (v)      the Company has delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel (which may rely upon an
Officers' Certificate as to factual matters), in each case stating that all
conditions precedent provided for herein relating to the defeasance contemplated
by this Section 7.3 have been complied with.

                  (c)      Notwithstanding the foregoing clause (b)(i), prior to
the end of the 123-day period referred to in clause (b)(iv)(B)(2) above, none of
the Company's obligations under this Indenture with respect to such Series shall
be discharged. Subsequent to the end of such 123-day period with respect to this
Section 7.3, the Company's obligations in Sections 2.2, 2.3, 2.4, 2.5, 2.6, 2.7,
2.8, 2.12, 3.1, 3.2, 6.7, 6.8, 7.6 and 7.7 shall survive with respect to such
Series until the Series is no longer outstanding. Thereafter, only the Company's
obligations in Sections 6.7, 7.6 and 7.7 shall survive with respect to such
Series. If and when a ruling from the Internal Revenue Service or Opinion of
Counsel referred to in clause (b)(iv)(A) above is able to be provided
specifically without regard to, and not in reliance upon, the continuance of the
Company's obligations under Section 3.1, then the Company's obligations under
such Section 3.1 with respect to such Series shall cease upon delivery to the
Trustee of such ruling or Opinion of Counsel and compliance with the other
conditions precedent provided for herein relating to the defeasance contemplated
by this Section 7.3.

                  (d)      After any such irrevocable deposit and the
fulfillment of the other requirements of this Section 7.3, the Trustee upon
written request shall acknowledge in writing the discharge of the Company's
obligations under the Securities of such Series and this Indenture with respect
to such Series except for those surviving obligations in paragraph (c) above.

                  (e)      Before or after a deposit pursuant to this Section
7.3, the Company may make arrangements satisfactory to the Trustee for the
redemption of Securities at a future date in accordance with Article 9.

SECTION 7.4       DEFEASANCE OF CERTAIN OBLIGATIONS.

                  (a)      If so provided with respect to a Series of Securities
in accordance with Section 2.1, the Company may omit to comply with any term,
provision or condition set forth in any covenant established with respect to
such Series pursuant to Section 2.1(b(ix), and clause (c) of Section 5.1 with
respect to any such covenant, and clause (d) of Section 5.1 shall be deemed not
to be an Event of Default, in each case with respect to the outstanding
Securities of such Series, if:

                           (i)      with reference to this Section 7.4, the
Company has irrevocably deposited or caused to be irrevocably deposited with the
Trustee or Paying Agent (other than the Company or a Subsidiary or Affiliate of
the Company) and conveyed all right, title and interest for the benefit of the
Holders of such Series, under the terms of an irrevocable trust agreement in
form satisfactory to the Trustee as trust funds in trust, specifically pledged
as security for, and dedicated solely to, the benefit of such Holders, in and
to, (A) money in an amount, (B) U.S. Government Obligations that, through the
payment of interest and principal in respect thereof in accordance with their
terms, will provide, not later than one Business Day before the due date of any
payment referred to in this clause (i), money in an amount or (C) a combination
thereof in an amount sufficient, in the opinion of a nationally recognized firm
of independent public

accountants expressed in a written certification thereof delivered to the
Trustee, to pay and discharge, without consideration of any reinvestment of
interest and after payment of all federal, state and local taxes or other fees,
charges and assessments in respect thereof payable by the Trustee or Paying
Agent, the principal of and interest on the outstanding Securities of such
Series when due; provided, that the Trustee or Paying Agent shall have been
irrevocably instructed in writing to apply such money or the proceeds of such
U.S. Government Obligations to the payment of such principal and interest with
respect to such Series;

                           (ii)     such deposit will not result in or
constitute a Default or result in a breach or violation of, or constitute a
default under, any other agreement or instrument to which the Company is a party
or by which it is bound;

                           (iii)    no Default with respect to such Series shall

Company Act of 1940, (B) such Holders will not recognize income, gain or loss
for federal income tax purposes as a result of the Company's exercise of its
option under this Section 7.4 and will be subject to 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 option had not been exercised and (C) after the passage of 123 days
following the deposit (except, with respect to any trust funds for the account
of any Holder of such series who may be deemed to be an "insider" for purposes
of Title 11 of the United States Code, after one year following the deposit),
the trust funds will not be subject to the effect of Section 547 of the United
States Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law in
a case commenced by or against the Company under either such statute, and either
(1) the trust funds will no longer remain the property of the Company (and
therefore, will not be subject to the effect of any applicable bankruptcy,
insolvency, reorganization or similar laws affecting creditors' rights
generally) or (2) if a court were to rule under any such law in any case or
proceeding that the trust funds remained property of the Company, (x) assuming
such trust funds remained in the possession of the Trustee prior to such court
ruling to the extent not paid to Holders of such Series, the Trustee will hold,
for the benefit of such Holders, a valid and perfected security interest in such
trust funds that is not avoidable in bankruptcy or otherwise except for the
effect of Section 552(b) of the United States Bankruptcy Code on interest on the

fulfillment of the other requirements of this Section 7.4, the Trustee upon
written request shall acknowledge in writing

                                       35

<PAGE>

the discharge of such of the Company's obligations under the Securities of such
Series and this Indenture with respect to such Series as the Company may omit to
comply with pursuant to this Section 7.4.

                  (c)      Before or after a deposit pursuant to this Section
7.4, the Company may make arrangements satisfactory to the Trustee for the
redemption of Securities at a future date in accordance with Article 9.

SECTION 7.5       APPLICATION OF TRUST MONEY.

                  Subject to Section 7.7 of this Indenture, the Trustee or
Paying Agent shall hold in trust money or U.S. Government Obligations deposited
with it pursuant to Section 7.1, 7.2, 7.3 or 7.4 of this Indenture, as the case
may be, and shall apply the deposited money and the money from U.S. Government
Obligations in accordance with this Indenture to the payment of principal of and
interest on the Securities of the relevant Series. Money held by the Trustee in
trust hereunder need not be segregated from other funds except to the extent
required by applicable law; provided, that the Paying Agent shall at all times

applicable law. The Trustee shall be under no obligation to invest such money or
U.S. Government Obligations and in no event shall the Trustee have any liability

Indenture, the Trustee and the Paying Agent shall promptly pay to the Company
upon written request any excess money or U.S. Government Obligations held by
them at any time pursuant to this Article 7, which in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee (which delivery shall
only be required if U.S. Government Obligations have been so provided), are in
excess of the amount thereof which would then be required to be deposited to
effect an equivalent discharge or defeasance in accordance with this Article 7,
and thereupon shall be relieved from all liability with respect to such money.
The Trustee and the Paying Agent shall pay to the Company upon written request
any money held by them for the payment of principal or interest of any Series
that remains unclaimed for two years; provided, that the Company shall if
requested by the Trustee or the Paying Agent, give the Trustee or such Paying
Agent indemnification reasonably satisfactory to it against any and all
liability which may be incurred by it by reason of such payment. After payment
to the Company, Holders entitled to such money must look to the Company for
payment as general creditors unless an applicable law designates another person,
and all liability of the Trustee and such Paying Agent with respect to such
money shall cease.

SECTION 7.7       REINSTATEMENT.

U.S. Government Obligations in accordance with Section 7.1, 7.2, 7.3 or 7.4 of
this Indenture, as the case may be, by reason of any legal proceeding or by
reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company's
obligations under this Indenture and the Securities of the applicable Series
shall be

                                       36

revived and reinstated as though no deposit had occurred pursuant to Section
7.1, 7.2, 7.3 or 7.4 of this Indenture, as the case may be, until such time as
the Trustee or Paying Agent is permitted to apply all such money or U.S.
Government Obligations in accordance with Section 7.1, 7.2, 7.3 or 7.4 of this
Indenture, as the case may be; provided, that, if the Company has made any
payment of principal of or interest on any Series of Securities because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Series to receive such payment from the money or U.S.
Government Obligations held by the Trustee or Paying Agent.

SECTION 7.8       DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
                  TRUST: MISCELLANEOUS PROVISIONS.

tax, fee or other charge imposed on or assessed against the U.S. Government
Obligations deposited or the principal and interest received in respect thereof

payment record dates as necessary to conform to then-current market practice; or

                           (viii)   to provide for the issuance of Securities
with terms not currently contemplated by Section 2.1.

                  (b)      After an amendment or supplement pursuant this
Section 8.1 becomes effective, the Company shall mail to Securityholders a
notice briefly describing such amendment or supplement. The failure to give such
notice to all Securityholders, or any defect therein, shall not impair or affect
the validity of an amendment or supplement under this Section 8.1.

SECTION 8.2       WITH CONSENT OF HOLDERS.

                  (a)      The Company, when authorized by a Board Resolution,
and the Trustee may amend or supplement this Indenture with respect to any one
or more Securities with the written consent of the Holders of a majority in
principal amount of the Securities of such Series affected by such amendment or
supplement. However, without the consent of each Securityholder of each Series
affected, an amendment or supplement under this Section 8.2 may not:

                           (i)      reduce the amount of Securities the Holders
of which must consent to an amendment or supplement or waiver;

                           (ii)     reduce the rate of or change the time for
payment of interest on any Security;

                           (iii)    reduce the principal of or change the Stated
Maturity of any Security;

                           (iv)     modify any redemption or repurchase right to
the detriment of a Holder;

                           (v)      make any Security payable in currency or
consideration other than that stated in the Security;

                           (vi)     make any change in Section 5.4, Section 5.7
or this second sentence of this Section 8.2(a).

                  (b)      An amendment or supplement which changes or
eliminates any covenant or other provision of this Indenture which has expressly
been included solely for the benefit of one or more particular Series of
Securities, or which modifies the rights of the Holders of Securities of such
Series with respect to such covenant or other provision, shall be deemed not to
affect the rights under this Indenture of the Holders of Securities of any other
Series.

<PAGE>

                  (c)      It shall not be necessary for the consent of the
Holders under this Section 8.2 to approve the particular form of any proposed
amendment or supplement, but it shall be sufficient if such consent approves the
substance thereof.

                  (d)      After an amendment or supplement under this Section
8.2 becomes effective, the Company shall mail to Securityholders a notice
briefly describing such amendment or supplement. The failure to give such notice
to all Securityholders, or any defect therein, shall not impair or affect the
validity of an amendment or supplement under this Section 8.2.

SECTION 8.3       COMPLIANCE WITH TRUST INDENTURE ACT.

                  Every amendment or supplement to this Indenture or the
Securities shall be set forth in a supplemental indenture that complies with the
TIA as then in effect.

SECTION 8.4       REVOCATION AND EFFECT OF CONSENTS.

                  Until an amendment, supplement or waiver under this Article 8
becomes effective, a consent to it by a Holder of any Security is a continuing
consent by the Holder and every subsequent Holder of Securities of that Series
or portion thereof that evidences the same debt as the consenting Holder's
Security, even if notation of the consent is not made on any Security. However,
any such Holder or subsequent Holder may revoke the consent as to his Security
or portion of a Security if the Trustee receives the notice of revocation before
the date the amendment, supplement or waiver becomes effective. After an
amendment or supplement becomes effective, it shall bind every Securityholder of
the affected Series.

SECTION 8.5       NOTATION ON OR EXCHANGE OF SECURITIES.

                  If an amendment changes the terms of a Security, the Trustee
may require the Holders of the Security to deliver it to the Trustee. The
Trustee may place an appropriate notation on the Securities of such Series
regarding the changed terms and return it to the Holders. Alternatively, if the
Company or the Trustee so determines, the Company in exchange for the Securities
of such Series shall issue and the Trustee shall authenticate new Securities of
such Series that reflect the changed terms. Failure to make the appropriate
notation or to issue new Securities of such Series shall not affect the validity
of such amendment.

SECTION 8.6       TRUSTEE TO SIGN AMENDMENTS.

                  The Trustee shall sign any supplemental indenture which sets
forth an amendment or supplement authorized pursuant to this Article 8 if the
amendment or supplement does not adversely affect the rights, duties,
liabilities or immunities of the Trustee under this Indenture or otherwise. If
it does, the Trustee may but need not sign it. In signing such supplemental
indenture the Trustee shall be entitled to receive indemnification reasonably
acceptable to it and to receive, and (subject to Section 6.1) shall be fully
protected in relying upon, an Officers' Certificate and an Opinion of Counsel
stating that such supplemental indenture is authorized or permitted by this
Indenture and, with respect to an amendment or supplement pursuant to Section
8.2, evidence of the consents of Holders required in connection therewith.

SECTION 8.7       FIXING OF RECORD DATES.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Holders entitled to take any action
under this Indenture by vote or consent. Except as provided herein, such record
date shall be the later of 30 days prior to the first solicitation of such
consent or vote or the date of the most recent list of Securityholders furnished
to the Trustee pursuant to Section 2.6 prior to such solicitation. If a record
date is fixed, those Persons who were Securityholders at such record date (or
their duly designated proxies), and only those Persons, shall be entitled to
take such action by vote or consent or to revoke any vote or consent previously
given, whether or not such Persons continue to be Holders after such record
date; provided, that unless such vote or consent is obtained from the Holders
(or their duly designated proxies) of the requisite principal amount of
outstanding Securities prior to the date which is 120 days after such record
date, any such vote or consent previously given shall automatically and without
further action by any Holder be canceled and of no further effect.

                             ARTICLE 9 - REDEMPTION

SECTION 9.1       APPLICABILITY OF ARTICLE.

                  Securities of any Series which are redeemable before their
Stated Maturity shall be redeemable in accordance with their terms and (except

Article 9.

SECTION 9.2       ELECTION TO REDEEM; NOTICE TO TRUSTEE.

                  The election of the Company to redeem Securities of any Series
shall be evidenced by a resolution of the Board of Directors. In case of any
redemption at the election of the Company, the Company shall, at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee in writing of such
Redemption Date and of the principal amount of Securities of such Series to be
redeemed. In the case of any redemption of such Securities (a) prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture or (b) that is subject to compliance
with any conditions provided for in the terms of such Securities or elsewhere in
this Indenture, the Company shall furnish the Trustee with an Officers'
Certificate confirming compliance with such restriction or conditions.

SECTION 9.3       SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

                  (a)      If less than all the Securities of the Series are to
be redeemed, the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee, from the outstanding
Securities of such Series not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to authorized denominations for
Securities of that Series) of the principal amount of Securities of such Series.

                  (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.

                                       40

<PAGE>

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

SECTION 9.4       NOTICE OF REDEMPTION.

                  (a)      Notice of redemption shall be given by first-class
mail, postage prepaid, mailed not less than 30 days nor more than 60 days prior
to the Redemption Date, to each Holder of Securities to be redeemed, at such
Holder's registered address.

                  (b)      All notices of redemption shall identify the
Securities to be redeemed (including CUSIP and, if applicable, ISIN and Common
Code numbers) and shall state:

                           (i)      the Redemption Date,

                           (ii)     the Redemption Price,

                           (iii)    if less than all the outstanding Securities
of such Series are to be redeemed, the identification (and, in the case of
partial redemption, the principal amounts) of the particular Securities to be
redeemed,

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

                           (v)      the place or places where such Securities
are to be surrendered for payment of the Redemption Price, and

                           (vi)     that the redemption is for a sinking fund,
if such is the case.

                  (c)      Notice of redemption of Securities of any Series to
be redeemed at the election of the Company shall be given by the Company or, at
the Company's request, by the Trustee in the name and at the expense of the
Company. The notice if mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the Holder
receives such notice. In any case, a failure to give such notice by mail or any
defect in the notice to the Holder of any Security designated for redemption as
a whole or in part shall not affect the validity of the proceedings for the
redemption of any other Security.

SECTION 9.5       DEPOSIT OF REDEMPTION PRICE.

                  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, that installments of interest
whose Stated Maturity is on or prior to

                                       41

<PAGE>

the Redemption Date shall be payable to the Holders of such Securities
registered as such at the close of business on the relevant record dates
according to their terms. If any Security called for redemption shall not be so
paid upon surrender thereof for redemption, the principal shall, until paid,
bear interest from the Redemption Date at the rate prescribed therefor in the
Security.

SECTION 9.6       SECURITIES REDEEMED IN PART.

                  Any Security which is to be redeemed only in part shall be
surrendered at the office of the Paying Agent (with, if the Company or the
Trustee for such Security so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company and the Trustee duly
executed by, the Holder thereof or his attorney duly authorized in writing), and
the Company shall execute a written order signed by two Officers and the Trustee
shall, upon receipt of such order, authenticate and deliver to the Holder of
such Security without service charge, a new Security or Securities of the same
Series, of any authorized denomination as requested by such Holder, in aggregate
principal amount equal to and in exchange for the unredeemed portion of the
principal of the Security so surrendered.

                           ___% [SENIOR] NOTE DUE_____

Holders must surrender Securities to a Paying Agent to collect principal
payments. The Company will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts. However, the Company may pay principal and interest by check
payable in such money. It may mail an interest check to a Holder's registered
address.

                  (3)      Paying Agent, Registrar. Initially, Wilmington Trust
Company, a Delaware banking corporation (the "Trustee"), will act as Paying
Agent and Registrar. The Company may change any Paying Agent or Registrar
without notice. The Company may act as Paying Agent or Registrar.

                  (4)      Indenture. The Company issued the Securities of this
Series under an Indenture dated as of ___________ ____, 2003 (the "Indenture")
between the Company and the Trustee. The Securities are unsecured general
obligations of the Company issued and to be issued in one or more Series under
the Indenture and may be issued in an unlimited principal amount. The terms of
the Securities include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code Sections
77aaa-77bbbb) (the "TIA"). Capitalized terms used herein but not defined herein
are used as defined in the Indenture. The Securities are subject to all such
terms, and Securityholders are referred to the Indenture and the TIA for a
statement of such terms.

                  (5)      Redemption. [set forth redemption provisions if any.]

                  (6)      Denominations; Transfer; Exchange. The Securities of
this Series are in registered form without coupons in denominations as set forth

Indenture. The Company shall not be required (a) to issue, register the transfer
of or exchange any Securities of a Series during a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 9.3 of
the Indenture and ending at the close of business on the day of such mailing or
(b) to register the transfer of or exchange any Security so selected for
redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part.

                  (7)      Defeasance. Subject to certain conditions and unless
otherwise provided in the terms of the Securities of this Series, the Company at
any time may terminate some or all of its obligations under the Securities and
the Indenture if the Company deposits with the Trustee money and/or U.S.
Government Obligations for the payment of principal and interest on the
Securities to maturity.

                  (8)      Persons Deemed Owners. The registered Holder of a
Security may be treated as its owner for all purposes, except that interest
(other than Defaulted Interest) will be paid to the person that was the
registered Holder on the relevant record date for such payment of interest.

                  (9)      Amendments and Waivers. Subject to certain
exceptions, (a) the Indenture or the Securities may be amended or supplemented
with the consent of the Holders of a majority in principal amount of the
Securities of each Series affected; and (b) any existing default with respect to
the Securities of this Series may be waived with the consent of the Holders of a
majority in principal amount of the Securities of such Series. Without the
consent of any Securityholder, the Indenture or the Securities may be amended or
supplemented to cure any ambiguity, omission, defect or inconsistency, to
provide for assumption of Company obligations to Securityholders or to provide
for uncertificated Securities in addition to or in place of certificated
Securities, to provide for guarantees with respect to, or security for, the
Securities, or to comply with the TIA or to add additional covenants or
surrender Company rights, or to make any change that does not adversely affect
the rights of any Securityholder.

                  (10)     Remedies. If an Event of Default with respect to the
Securities of this Series occurs and is continuing, the Trustee or Holders of at
least 25% in principal amount of the Securities of this Series may declare all
the Securities of this Series to be due and payable immediately. Securityholders
may not enforce the Indenture or the Securities of this Series except as
provided in the Indenture. The Trustee may require an indemnity before it
enforces the Indenture or the Securities. Subject to certain limitations,
Holders of a majority in principal amount of the Securities of a Series may
direct the Trustee in its exercise of any trust or power with respect to such
Series. The Trustee may withhold from Securityholders notice of any continuing
default (except a Default in payment of principal or interest) if it determines
that withholding notice is in their interests. The Company must furnish an
annual compliance certificate to the Trustee.

                  (11)     Trustee Dealings with Company. Subject to the
provisions of the TIA, the Trustee under the Indenture, in its individual or any
other capacity, may make loans to, accept deposits from and perform services for
the Company or its Affiliates, and may otherwise deal with the Company or its
Affiliates, as if it were not Trustee. The Trustee will initially be Wilmington
Trust Company.

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

                  (13)     Authentication. This Security shall not be valid
