one or more indentures supplemental hereto, in each case with such appropriate insertions,
omissions, substitutions and other variations as are required or permitted by this Indenture and
may have imprinted or otherwise reproduced thereon such legend or legends or endorsements, not
inconsistent with the provisions of this Indenture, as may be required to comply with any law or
with any rules or regulations pursuant thereto, or with any rules of any securities exchange or to
conform to general usage, all as may be determined by the officers executing such Securities as
evidenced by their execution of such Securities.

     The definitive Securities shall be printed, lithographed or engraved on steel engraved borders

as evidenced by their execution of such Securities.

     The Issuer may from time to time, without notice to or the consent of the holders of any
series of Securities, create and issue further Securities of any such series ranking equally with
the Securities of such series in all respects (or in all respects other than (1) the payment of
interest accruing prior to the issue date of such further Securities or (2) the first payment of
interest following the issue date of such further Securities). Such further Securities may be
consolidated and form a single series with the Securities of such series and have the same terms as
to status, redemption or otherwise as the Securities of such series.

     Section 2.04 Authentication and Delivery of Securities. The Issuer may deliver Securities of any
series executed by the Issuer to the Trustee for authentication together with the applicable
documents referred to below in this Section, and the Trustee shall thereupon authenticate and
deliver such Securities to or upon the order of the Issuer (contained in the Issuer Order referred
to below in this Section) or pursuant to such procedures acceptable to the Trustee and to such
recipients as may be specified from time to time by an Issuer Order. The maturity date, original
issue date, interest rate and any other terms of the Securities of such series shall be determined
by or pursuant to such Issuer Order and procedures. If provided for in such procedures, such
Issuer Order may authorize authentication and delivery pursuant to oral instructions from the
Issuer or its duly authorized agent, which instructions shall be promptly confirmed in writing. In
authenticating such Securities and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section
6.01) shall be fully protected in relying upon:

          (a) an Issuer Order requesting such authentication and setting forth delivery instructions if
the Securities are not to be delivered to the Issuer;

          (b) any Board Resolution, Officer’s Certificate and/or executed supplemental indenture
referred to in Sections 2.01 and 2.03 by or pursuant to which the forms and terms of the Securities
were established;

          (c) an Officer’s Certificate setting forth the form or forms and terms of the Securities
stating that the form or forms and terms of the Securities have been established pursuant to
Sections 2.01 and 2.03 and comply with this Indenture, and covering such other matters as the
Trustee may reasonably request; and

          (d) an Opinion of Counsel to the effect that:

    (i) the form or forms and terms of such Securities have been established
pursuant to Sections 2.01 and 2.03 and comply with this Indenture,

    (ii) the authentication and delivery of such Securities by the Trustee are
authorized under the provisions of this Indenture,

    (iii) such Securities when authenticated and delivered by the Trustee and
issued by the Issuer in the manner and subject to any conditions specified in such
Opinion of Counsel, will constitute valid and binding obligations of the Issuer, and

-9-

 

     (iv) all laws and requirements in respect of the execution and delivery
by the Issuer of the Securities have been complied with,

     and covering such other matters as the Trustee may reasonably request.

     The Trustee shall have the right to decline to authenticate and deliver any Securities under
this Section if the Trustee, being advised by counsel, determines that such action may not lawfully
be taken by the Issuer or if the Trustee in good faith by its board of directors or board of
trustees, executive committee, or a trust committee of directors or trustees or Responsible
Officers 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, this Indenture or otherwise.

     The Issuer shall execute and the Trustee shall, in accordance with this Section with respect
to the Securities of a series, authenticate and deliver one or more Global Securities that (i)
shall represent and shall be denominated in an amount equal to the aggregate principal amount of
all of the Securities of such series issued and not yet cancelled, (ii) shall be registered in the
name of the Depositary for such Global Security or Securities or the nominee of such Depositary,
(iii) shall be delivered by the Trustee to such Depositary or pursuant to such Depositary’s
instructions and (iv) shall bear a legend substantially to the following effect: “Unless and until
it is exchanged in whole or in part for Securities in definitive registered form, this Security may
not be transferred except as a whole by the Depositary to the nominee of the Depositary or by a
nominee of the Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such successor
Depositary.”

     Each Depositary designated pursuant to this Section must, at the time of its designation and
at all times while it serves as Depositary, be a clearing agency registered under the Securities
Exchange Act of 1934 and any other applicable statute or regulation.

     Section 2.05 Execution of Securities. The Securities shall be signed on behalf of the Issuer by
the chairman of its Board of Directors, any vice chairman of its Board of Directors, its chief
executive officer, its principal financial officer, its president, any vice president or its
treasurer. Such signatures may be the manual or facsimile signatures of the present or any future
such officers. Typographical and other minor errors or defects in any such reproduction of any
such signature shall not affect the validity or enforceability of any Security that has been duly
authenticated and delivered by the Trustee.

     In case any officer of the Issuer who shall have signed any of the Securities shall cease to
be such officer before the Security so signed shall be authenticated and delivered by the Trustee
or disposed of by the Issuer, such Security nevertheless may be authenticated and delivered or
disposed of as though the person who signed such Security had not ceased to be such officer of the
Issuer; and any Security may be signed on behalf of the Issuer by such persons as, at the actual
date of the execution of such Security, shall be the proper officers of the Issuer, although at the
date of the execution and delivery of this Indenture any such person was not such an officer.

-10-

 

     Section 2.06 Certificate of Authentication. Only such Securities as shall bear thereon a
certificate of authentication substantially in the form hereinbefore recited, executed by the
Trustee by the manual signature of one of its authorized officers, shall be entitled to the
benefits of this Indenture or be valid or obligatory for any purpose. The execution of such
certificate by the Trustee upon any Security executed by the Issuer shall be conclusive evidence
that the Security so authenticated has been duly authenticated and delivered hereunder and that the
Holder is entitled to the benefits of this Indenture.

     Section 2.07 Denomination and Date of Securities; Payments of Interest. The Securities of each
series shall be issuable in denominations established as contemplated by Section 2.03 or, if not so
established, in denominations of $1,000 and any integral multiple thereof. The Securities of each
series shall be numbered, lettered or otherwise distinguished in such manner or in accordance with
such plan as the officers of the Issuer executing the same may determine with the approval of the
Trustee, as evidenced by the execution and authentication thereof. Unless otherwise indicated in a
Board Resolution, Officer’s Certificate or supplemental indenture for a particular series, interest
will be calculated on the basis of a 360-day year of twelve 30-day months.

     Each Security shall be dated the date of its authentication. The Securities of each series
shall bear interest, if any, from the date, and such interest shall be payable on the dates,
established as contemplated by Section 2.03.

     The Person in whose name any Security of any series is registered at the close of business on
any record date applicable to a particular series with respect to any interest payment date for
such series shall be entitled to receive the interest, if any, payable on such interest payment
date notwithstanding any transfer, exchange or conversion of such Security subsequent to the record
date and prior to such interest payment date, except if and to the extent the Issuer shall default
in the payment of the interest due on such interest payment date for such series, in which case
such defaulted interest shall be paid to the Persons in whose names Outstanding Securities for such
series are registered at the close of business on a subsequent record date (which shall be not less
than five Business Days prior to the date of payment of such defaulted interest) established by
notice given by mail by or on behalf of the Issuer to the Holders of Securities not less than 15
days preceding such subsequent record date. The term “record date” as used with respect to any
interest payment date (except a date for payment of defaulted interest) for the Securities of any
series shall mean the date specified as such in the terms of the Securities of such series
established as contemplated by Section 2.03, or, if no such date is so established, if such
interest payment date is the first day of a calendar month, the 15th day of the next preceding
calendar month or, if such interest payment date is the 15th day of a calendar month, the first day
of such calendar month, whether or not such record date is a Business Day.

     Section 2.08 Registration, Transfer and Exchange. The Issuer will keep at each office or agency to
be maintained for the purpose as provided in Section 3.02 for each series of Securities a register
or registers in which, subject to such reasonable regulations as it may prescribe, it will provide
for the registration of Securities of such series and the registration of transfer of Securities of
such series. Such register shall be in written form in the English language or in any other form
capable of being converted into such form within a reasonable

-11-

 

time. At all reasonable times such register or registers shall be open for inspection by the
Trustee.

     Upon due presentation for registration of transfer of any Security of any series at any such
office or agency to be maintained for the purpose as provided in Section 3.02, the Issuer shall
execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees
a new Security or Securities of the same series, maturity date, interest rate and original issue
date in authorized denominations for a like aggregate principal amount.

     At the option of the Holder thereof, Securities of any series (except a Global Security) may
be exchanged for a Security or Securities of such series having authorized denominations and an
equal aggregate principal amount, upon surrender of such Securities to be exchanged at the agency
of the Issuer that shall be maintained for such purpose in accordance with Section 3.02 and upon
payment, if the Issuer shall so require, of the charges hereinafter provided. Whenever any
Securities are so surrendered for exchange, the Issuer shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is entitled to
receive. All Securities surrendered upon any exchange or transfer provided for in this Indenture
shall be promptly cancelled and disposed of by the Trustee and the Trustee will deliver a
certificate of disposition thereof to the Issuer.

     All Securities presented for registration of transfer, exchange, redemption or payment shall
(if so required by the Issuer or the Trustee) be duly endorsed by, or be accompanied by a written
instrument or instruments of transfer in form satisfactory to the Issuer and the Trustee duly
executed by, the Holder or his or her attorney duly authorized in writing.

     The Issuer may require payment of a sum sufficient to cover any stamp or other tax or other
governmental charge that may be imposed in connection with any exchange or registration of transfer
of Securities. No service charge shall be made for any such transaction.

     The Issuer shall not be required to exchange or register a transfer of (a) any Securities of
any series for a period of 15 days next preceding the first mailing of notice of redemption of
Securities of such series to be redeemed or (b) any Securities selected, called or being called for
redemption, in whole or in part, except, in the case of any Security to be redeemed in part, the
portion thereof not so to be redeemed.

     Notwithstanding any other provision of this Section 2.08, unless and until it is exchanged in
whole or in part for Securities 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
Depositary for such series to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to
a successor Depositary for such series or a nominee of such successor Depositary.

     If at any time the Depositary for the Securities of a series notifies the Issuer that it is
unwilling or unable to continue as Depositary for the Securities of such series or if at any time
the Depositary for the Securities of a series shall no longer be eligible under Section 2.04, the
Issuer shall appoint a successor Depositary with respect to the Securities of such series. If a
successor Depositary for the Securities of such series is not appointed by the Issuer within 90

-12-

 

days after the Issuer receives such notice or becomes aware of such ineligibility, the
Issuer’s determination pursuant to Section 2.03 that the Securities of such series be represented
by a Global Security shall no longer be effective and the Issuer will execute, and the Trustee,
upon receipt of an Officer’s Certificate for the authentication and delivery of definitive
Securities of such series, will authenticate and deliver, Securities of such series in definitive
registered form, in any authorized denominations, in an aggregate principal amount equal to the
principal amount of the Global Security or Securities representing the Securities of such series,
in exchange for such Global Security or Securities.

     The Issuer may at any time and in its sole discretion determine that the Securities of any
series issued in the form of one or more Global Securities shall no longer be represented by a
Global Security or Securities. In such event the Issuer will execute, and the Trustee, upon
receipt of an Officer’s Certificate for the authentication and delivery of definitive Securities of
such series, will authenticate and deliver, Securities of such series in definitive registered
form, in any authorized denominations, in an aggregate principal amount equal to the principal
amount of the Global Security or Securities representing such series, in exchange for such Global
Security or Securities.

     The Depositary for such Global Security may surrender such Global Security in exchange in
whole or in part for Securities of the same series in definitive registered form in accordance with
the two preceding paragraphs or on such other terms as are acceptable to the Issuer and such
Depositary. Thereupon, the Issuer shall execute, and the Trustee shall authenticate and deliver,
without service charge,

     (i) to the Person specified by such Depositary a new Security or Securities of
the same series, of any authorized denominations as requested by such Person, in an
aggregate principal amount equal to and in exchange for such Person’s beneficial
interest in the Global Security; and

     (ii) to such Depositary a new Global Security in a denomination equal to the
difference, if any, between the principal amount of the surrendered Global Security
and the aggregate principal amount of Securities authenticated and delivered
pursuant to clause (i) above.

     Upon the exchange of a Global Security for Securities in definitive registered form, 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 2.08
shall be registered in such names and in such authorized denominations as the Depositary for such
Global Security, pursuant to instructions from its direct or indirect participants or otherwise,
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.

     All Securities issued upon any transfer or exchange of Securities shall be valid obligations
of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as
the Securities surrendered upon such transfer or exchange.

-13-

 

     Section 2.09 Mutilated, Defaced, Destroyed, Lost and Stolen Securities. In case any temporary or
definitive Security shall become mutilated, defaced or be destroyed, lost or stolen, the Issuer in
its discretion may execute, and upon the written request of any officer of the Issuer, the Trustee
shall authenticate and deliver a new Security of the same series, maturity date, interest rate and
original issue date, bearing a number or other distinguishing symbol not contemporaneously
outstanding, in exchange and substitution for the mutilated or defaced Security, or in lieu of and
substitution for the Security so destroyed, lost or stolen. In every case the applicant for a
substitute Security shall furnish to the Issuer and to the Trustee and any agent of the Issuer or
the Trustee such security or indemnity as may be required by them to indemnify and defend and to
save each of them harmless and, in every case of destruction, loss or theft, evidence to their
satisfaction of the destruction, loss or theft of such Security and of the ownership thereof and in
the case of mutilation or defacement shall surrender the Security to the Trustee.

     Upon the issuance of any substitute Security, the Issuer may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in relation thereto
and any other expenses (including the fees and expenses of the Trustee) connected therewith. In
case any Security which has matured or is about to mature or has been called for redemption in
full, or is being surrendered for conversion in full, shall become mutilated or defaced or be
destroyed, lost or stolen, the Issuer may, instead of issuing a substitute Security (with the
Holder’s consent, in the case of convertible Securities), pay or authorize the payment of the same
or convert, or authorize conversion of the same (without surrender thereof except in the case of a
mutilated or defaced Security), if the applicant for such payment shall furnish to the Issuer and
to the Trustee and any agent of the Issuer or the Trustee such security or indemnity as any of them
may require to save each of them harmless, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Issuer and the Trustee and any agent of the Issuer or the
Trustee evidence to their satisfaction of the destruction, loss or theft of such Security and of
the ownership thereof.

     Every substitute Security of any series issued pursuant to the provisions of this Section by
virtue of the fact that any such Security is destroyed, lost or stolen shall constitute an
additional contractual obligation of the Issuer, whether or not the destroyed, lost or stolen
Security shall be at any time enforceable by anyone and shall be entitled to all the benefits of
(but shall be subject to all the limitations of rights set forth in) this Indenture equally and
proportionately with any and all other Securities of such series duly authenticated and delivered
hereunder. All Securities shall be held and owned upon the express condition that, to the extent
permitted by law, the foregoing provisions are exclusive with respect to the replacement or payment
or conversion of mutilated, defaced or destroyed, lost or stolen Securities and shall preclude any
and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted
to the contrary with respect to the replacement or payment of negotiable instruments or other
securities without their surrender.

     Section 2.10 Cancellation of Securities; Destruction Thereof. All Securities surrendered for
exchange for Securities of the same series or for payment, redemption, registration of transfer,
conversion or for credit against any payment in respect of a sinking or analogous fund, if
surrendered to the Issuer or any agent of the Issuer or the Trustee, shall be delivered to the
Trustee for cancellation or, if surrendered to the Trustee, shall be cancelled by it;

-14-

 

and no Securities shall be issued in lieu thereof except as expressly permitted by any of the
provisions of this Indenture. The Trustee shall dispose of cancelled Securities held by it and
deliver a certificate of disposition to the Issuer. If the Issuer shall acquire any of the
Securities, such acquisition shall not operate as a redemption or satisfaction of the Debt
represented by such Securities unless and until the same are delivered to the Trustee for
cancellation.

     Section 2.11 Temporary Securities. Pending the preparation of definitive Securities for any
series, the Issuer may execute and the Trustee shall authenticate and deliver temporary Securities
for such series (printed, lithographed, typewritten or otherwise reproduced, in each case in form
satisfactory to the Trustee). Temporary Securities of any series shall be issuable in any
authorized denomination, and substantially in the form of the definitive Securities of such series
but with such omissions, insertions and variations as may be appropriate for temporary Securities,
all as may be determined by the Issuer with the concurrence of the Trustee as evidenced by the
execution and authentication thereof. Temporary Securities may contain such reference to any
provisions of this Indenture as may be appropriate. Every temporary Security shall be executed by
the Issuer and be authenticated by the Trustee upon the same conditions and in substantially the
same manner, and with like effect, as the definitive Securities. Without unreasonable delay the
Issuer shall execute and shall furnish definitive Securities of such series and thereupon temporary
Securities of such series may be surrendered in exchange therefor without charge at each office or
agency to be maintained by the Issuer for that purpose pursuant to Section 3.02 and the Trustee
shall authenticate and deliver in exchange for such temporary Securities of such series an equal
aggregate principal amount of definitive Securities of the same series having authorized
denominations. Until so exchanged, the temporary Securities of any series shall be entitled to the
same benefits under this Indenture as definitive Securities of such series, unless the benefits of
the temporary Securities are limited pursuant to Section 2.03.

ARTICLE 3

COVENANTS OF THE ISSUER

     Section 3.01 Payment of Principal and Interest. The Issuer covenants and agrees for the benefit of
each series of Securities that it will duly and punctually pay or cause to be paid the principal
of, and interest on, each of the Securities of such series (together with any additional amounts
payable pursuant to the terms of such Securities) at the place or places, at the respective times
and in the manner provided in such Securities and in this Indenture. The interest on Securities
(together with any additional amounts payable pursuant to the terms of such Securities) shall be
payable only to or upon the written order of the Holders thereof and at the option of the Issuer
may be paid by mailing checks for such interest payable to or upon the written order of such
Holders at their last addresses as they appear on the Security register of the Issuer.

     Section 3.02 Offices for Payments, Etc. The Issuer will maintain (i) in _______, an agency where
the Securities of each series may be presented for payment, an agency where the Securities of each
series may be presented for exchange and conversion, if applicable, as provided in this Indenture
and an agency where the Securities of each series may be presented for registration of transfer as
in this Indenture provided and (ii) such further agencies in such places as may be determined for
the Securities of such series pursuant to Section 2.03.

-15-

 

     The Issuer will maintain in                     , an agency where notices and demands to or upon the
Issuer in respect of the Securities of any series or this Indenture may be served.

     The Issuer will give to the Trustee written notice of the location of each such agency and of
any change of location thereof. In case the Issuer shall fail to maintain any agency required by
this Section to be located in                     , or shall fail to give such notice of the location or of
any change in the location of any of the above agencies, presentations and demands may be made and
notices may be served at the Corporate Trust Office of the Trustee.

     The Issuer may from time to time designate one or more additional agencies where the
Securities of a series may be presented for payment, where the Securities of that series may be
presented for exchange or conversion, if applicable, as provided in this Indenture and pursuant to
Section 2.03 and where the Securities of that series may be presented for registration of transfer
as in this Indenture provided, and the Issuer may from time to time rescind any such designation,
as the Issuer may deem desirable or expedient; provided, however, that no such designation or
rescission shall in any manner relieve the Issuer of its obligation to maintain the agencies
provided for in this Section. The Issuer will give to the Trustee prompt written notice of any
such designation or rescission thereof.

     Section 3.03 Appointment to Fill a Vacancy in Office of Trustee. The Issuer, whenever necessary to
avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section
6.10, a Trustee, so that there shall at all times be a Trustee with respect to each series of
Securities hereunder.

     Section 3.04 Paying Agents. Whenever the Issuer shall appoint a paying agent other than the
Trustee with respect to the Securities of any series, it will cause such paying agent to execute
and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject
to the provisions of this Section,

          (a) that it will hold all sums received by it as such agent for the payment of the principal
of or interest on the Securities of such series (whether such sums have been paid to it by the
Issuer or by any other obligor on the Securities of such series) in trust for the benefit of the
Holders of the Securities of such series or of the Trustee,

          (b) that it will give the Trustee notice of any failure by the Issuer (or by any other obligor
on the Securities of such series) to make any payment of the principal of or interest on the
Securities of such series when the same shall be due and payable, and

          (c) that at any time during the continuance of any such failure, upon the written request of
the Trustee, it will forthwith pay to the Trustee all sums so held in trust by such paying agent.

     The Issuer will, on or prior to each due date of the principal of or interest on the
Securities of such series, deposit with the paying agent a sum sufficient to pay such principal or
interest so becoming due, and (unless such paying agent is the Trustee) the Issuer will promptly
notify the Trustee of any failure to take such action.

-16-

 

     If the Issuer shall act as its own paying agent with respect to the Securities of any series,
it will, on or before each due date of the principal of or interest on the Securities of such
series, set aside, segregate and hold in trust for the benefit of the Holders of the Securities of
such series a sum sufficient to pay such principal or interest so becoming due. The Issuer will
promptly notify the Trustee of any failure to take such action.

     Anything in this Section to the contrary notwithstanding, but subject to Section 10.01, the
Issuer may at any time, for the purpose of obtaining a satisfaction and discharge with respect to
one or more or all series of Securities hereunder, or for any other reason, pay or cause to be paid
to the Trustee all sums held in trust for any such series by the Issuer or any paying agent
hereunder, as required by this Section, such sums to be held by the Trustee upon the trusts herein
contained.

     Anything in this Section to the contrary notwithstanding, the agreement to hold sums in trust
as provided in this Section is subject to the provisions of Sections 10.03 and 10.04.

     Section 3.05 Written Statement to Trustee. So long as any Securities are Outstanding hereunder,
the Issuer will deliver to the Trustee, within 120 days after the end of each fiscal year of the
Issuer ending after the date hereof, a written statement covering the previous fiscal year, signed
by two of its officers (which need not comply with Section 11.05), stating that in the course of
the performance of their duties as officers of the Issuer they would normally have knowledge of any
default by the Issuer in the performance or fulfillment of any covenant, agreement or condition
contained in this Indenture, stating whether or not they have knowledge of any such default and, if
so, specifying each such default of which the signers have knowledge and the nature thereof.

ARTICLE 5

REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS

ON EVENT OF DEFAULT

     Section 5.01 Event of Default Defined; Acceleration of Maturity; Waiver of Default. “Event of
Default”, with respect to Securities of any series wherever used herein, means each one of the
following events which shall have occurred and be continuing (whatever the reason for such Event of
Default and whether it shall be voluntary or involuntary or be effected by operation of law or
pursuant to any judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

          (a) default in the payment of any installment of interest upon any of the Securities of such
series as and when the same shall become due and payable, and continuance of such default for a
period of 30 days (or such other period as may be established for the Securities of such series as
contemplated by Section 2.03); or

          (b) default in the payment of all or any part of the principal on any of the Securities of
such series as and when the same shall become due and payable either at maturity, upon redemption,
by declaration or otherwise, and the continuance of such default (or such other period as may be
established for the Securities of such series as contemplated by Section 2.03); or

-18-

 

          (c) default in the performance, or breach, of any covenant or warranty of the Issuer in
respect of the Securities of such series (other than a covenant or warranty in respect of the
Securities of such series a default in the performance or breach of which is elsewhere in this
Section specifically dealt with), and continuance of such default or breach for a period of 60 days
after there has been given, by registered or certified mail, to the Issuer by the Trustee or to the
Issuer and the Trustee by the Holders of at least 25% in principal amount of the Outstanding
Securities of all series affected thereby, a written notice specifying such default or breach and
requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or

          (d) a court having jurisdiction in the premises shall enter a decree or order for relief in
respect of the Issuer in an involuntary case under any applicable bankruptcy, insolvency or other
similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian,
trustee or sequestrator (or similar official) of the Issuer or for all or substantially all of its
property and assets or ordering the winding up or liquidation of its affairs, and such decree or
order shall remain unstayed and in effect for a period of 60 consecutive days; or

          (e) the Issuer shall commence a voluntary case under any applicable bankruptcy, insolvency or
other similar law now or hereafter in effect, or consent to the entry of an order for relief in an
involuntary case under any such law, or consent to the appointment of or taking possession by a
receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the
Issuer or for any substantial part of its property and assets, or make any general assignment for
the benefit of creditors; or

          (f) any other Event of Default provided for in such series of Securities.

     If an Event of Default described in clauses (a), (b), (c) or (f) occurs and is continuing,
then, and in each and every such case, unless the principal of all of the Securities of such series
shall have already become due and payable, either the Trustee or the Holders of not less than 25%
in aggregate principal amount of the Securities of such series then Outstanding hereunder (each
such series voting as a separate class) by notice in writing to the Issuer (and also to the Trustee
if given by Securityholders), may declare the entire principal (or, if the Securities of such
series are Original Issue Discount Securities, such portion of the principal amount as may be
specified in the terms of such series) of all Securities of such series and the interest accrued
thereon, if any, to be due and payable immediately, and upon any such declaration the same shall
become immediately due and payable. If an Event of Default described in clauses (d) or (e) occurs
and is continuing, then and in each and every such case, the entire principal (or, if any
Securities are Original Issue Discount Securities, such portion of the principal as may be
specified in the terms thereof) of all the Securities then Outstanding and interest accrued
thereon, if any, shall become immediately due and payable.

     The foregoing provisions, however, are subject to the condition that if, at any time after the
principal (or, if the Securities are Original Issue Discount Securities, such portion of the
principal as may be specified in the terms thereof) of the Securities of any series (or of all the
Securities, as the case may be) shall have been so declared due and payable, and before any
judgment or decree for the payment of the moneys due shall have been obtained or entered as
hereinafter provided, the Issuer shall pay or shall deposit with the Trustee a sum sufficient to
pay all matured installments of interest upon all the Securities of such series (or of all the
Securities,

-19-

 

as the case may be) and the principal of any and all Securities of such series (or of all the
Securities, as the case may be) which shall have become due otherwise than by acceleration (with
interest upon such principal and, to the extent that payment of such interest is enforceable under
applicable law, on overdue installments of interest, at the same rate as the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities
of such series, (or at the respective rates of interest or Yields to Maturity of all the
Securities, as the case may be) to the date of such payment or deposit) and such amount as shall be
sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and
all other expenses and liabilities incurred, and all advances made, by the Trustee except as a
result of negligence or bad faith, and if any and all Events of Default under the Indenture, other
than the non-payment of the principal of Securities which shall have become due by acceleration,
shall have been cured, waived or otherwise remedied as provided herein—then and in every such case
the Holders of a majority in aggregate principal amount of all the Securities of such series, each
series voting as a separate class, (or of all the Securities, as the case may be, voting as a
single class) then Outstanding, by written notice to the Issuer and to the Trustee, may waive all
defaults with respect to such series (or with respect to all the Securities, as the case may be)
and rescind and annul such declaration and its consequences, but no such waiver or rescission and
annulment shall extend to or shall affect any subsequent default or shall impair any right
consequent thereon.

     For all purposes under this Indenture, if a portion of the principal of any Original Issue
Discount Securities shall have been accelerated and declared due and payable pursuant to the
provisions hereof, then, from and after such declaration, unless such declaration has been
rescinded and annulled, the principal amount of such Original Issue Discount Securities shall be
deemed, for all purposes hereunder, to be such portion of the principal thereof as shall be due and
payable as a result of such acceleration, and payment of such portion of the principal thereof as
shall be due and payable as a result of such acceleration, together with interest, if any, thereon
and all other amounts owing thereunder, shall constitute payment in full of such Original Issue
Discount Securities.

     Section 5.02 Collection of Debt by Trustee; Trustee May Prove Debt. The Issuer covenants that (a)
in case default shall be made in the payment of any installment of interest on any of the
Securities of any series when such interest shall have become due and payable, and such default
shall have continued for a period of 30 days or (b) in case default shall be made in the payment of
all or any part of the principal of any of the Securities of any series when the same shall have
become due and payable, whether upon maturity of the Securities of such series or upon any
redemption or by declaration or otherwise—then, upon demand of the Trustee, the Issuer will pay to
the Trustee for the benefit of the Holders of the Securities of such series the whole amount that
then shall have become due and payable on all Securities of such series for principal or interest,
as the case may be (with interest to the date of such payment upon the overdue principal and, to
the extent that payment of such interest is enforceable under applicable law, on overdue
installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case
of Original Issue Discount Securities) specified in the Securities of such series); and, in
addition thereto, such further amount as shall be sufficient to cover the costs and expenses of
collection, including reasonable compensation to the Trustee and each predecessor trustee, their
respective agents, attorneys and counsel, and any expenses and liabilities incurred,

-20-

 

and all advances made, by the Trustee and each predecessor trustee except as a result of its
negligence or bad faith.

     In case the Issuer shall fail forthwith to pay such amounts upon such demand, the Trustee, in
its own name and as trustee of an express trust, shall be entitled and empowered to institute any
action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceedings to judgment or final decree, and may enforce any such
judgment or final decree against the Issuer or other obligor upon such Securities and collect in
the manner provided by law out of the property of the Issuer or other obligor upon such Securities,
wherever situated, the moneys adjudged or decreed to be payable.

     In case there shall be pending proceedings relative to the Issuer or any other obligor upon
the Securities under Title 11 of the United States Code or any other applicable Federal or state
bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in
bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been
appointed for or taken possession of the Issuer or its property or such other obligor or its
property, or in case of any other comparable judicial proceedings relative to the Issuer or other
obligor upon the Securities of any series, or to the creditors or property of the Issuer or such
other obligor, the Trustee, irrespective of whether the principal of any Securities shall then be
due and payable as therein expressed or by declaration or otherwise and irrespective of whether the
Trustee shall have made any demand pursuant to the provisions of this Section, shall be entitled
and empowered, by intervention in such proceedings or otherwise:

     (i) to file and prove a claim or claims for the whole amount of principal and
interest (or, if the Securities of any series are Original Issue Discount
Securities, such portion of the principal amount as may be specified in the terms of
such series) owing and unpaid in respect of the Securities of any series, and to
file such other papers or documents as may be necessary or advisable in order to
have the claims of the Trustee (including any claim for reasonable compensation to
the Trustee and each predecessor trustee, and their respective agents, attorneys and
counsel, and for reimbursement of all expenses and liabilities incurred, and all
advances made, by the Trustee and each predecessor trustee, except as a result of
negligence or bad faith) and of the Securityholders allowed in any judicial
proceedings relative to the Issuer or other obligor upon the Securities of any
series, or to the creditors or property of the Issuer or such other obligor,

     (ii) unless prohibited by applicable law and regulations, to vote on behalf of
the Holders of the Securities of any series in any election of a trustee or a
standby trustee in arrangement, reorganization, liquidation or other bankruptcy or
insolvency proceedings or person performing similar functions in comparable
proceedings, and

     (iii) to collect and receive any moneys or other property payable or
deliverable on any such claims, and to distribute all amounts received with respect
to the claims of the Securityholders and of the Trustee on their behalf; and any
trustee, receiver or liquidator, custodian or other similar official is hereby

-21-

 

authorized by each of the Securityholders to make payments to the Trustee, and,
in the event that the Trustee shall consent to the making of payments directly to
the Securityholders, to pay to the Trustee such amounts as shall be sufficient to
cover reasonable compensation to the Trustee, each predecessor trustee and their
respective agents, attorneys and counsel, and all other expenses and liabilities
incurred, and all advances made, by the Trustee and each predecessor trustee except
as a result of negligence or bad faith and all other amounts due to the Trustee or
any predecessor trustee pursuant to Section 6.06.

     Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or vote for or accept or adopt on behalf of any Securityholder any plan of reorganization,
arrangement, adjustment or composition affecting the Securities of any series or the rights of any
Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Securityholder
in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or
similar person.

     All rights of action and of asserting claims under this Indenture, or under any of the
Securities of any series, may be enforced by the Trustee without the possession of any of the
Securities of such series or the production thereof on any trial or other proceedings relative
thereto, and any such action or proceedings instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment, subject to the payment of the
expenses, disbursements and compensation of the Trustee, each predecessor trustee and their
respective agents and attorneys, shall be for the ratable benefit of the Holders of the Securities
in respect of which such action was taken.

     In any proceedings brought by the Trustee (and also any proceedings involving the
interpretation of any provision of this Indenture to which the Trustee shall be a party), the
Trustee shall be held to represent all the Holders of the Securities in respect to which such
action was taken, and it shall not be necessary to make any Holders of such Securities parties to
any such proceedings.

     Section 5.03 Application of Proceeds. Any moneys collected by the Trustee pursuant to this Article
in respect of any series shall be applied in the following order at the date or dates fixed by the
Trustee and, in case of the distribution of such moneys on account of principal or interest, upon
presentation of the several Securities in respect of which monies have been collected and stamping
(or otherwise noting) thereon the payment, or issuing Securities of such series in reduced
principal amounts in exchange for the presented Securities of like series if only partially paid,
or upon surrender thereof if fully paid:

          FIRST: To the payment of all amounts due to the Trustee or any predecessor trustee pursuant
to Section 6.06;

          SECOND: In case the principal of the Securities of such series in respect of which moneys
have been collected shall not have become and be then due and payable, to the payment of interest
on the Securities of such series in default in the order of the maturity of the installments of
such interest, with interest (to the extent that such interest has been collected by the Trustee)
upon the overdue installments of interest at the same rate as the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) specified in such Securities,

-22-

 

such payments to be made ratably to the Persons entitled thereto, without discrimination or
preference;

          THIRD: In case the principal of the Securities of such series in respect of which moneys have
been collected shall have become and shall be then due and payable, to the payment of the whole
amount then owing and unpaid upon all the Securities of such series for principal and interest,
with interest upon the overdue principal, and (to the extent that such interest has been collected
by the Trustee) upon overdue installments of interest at the same rate as the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities
of such series; and in case such moneys shall be insufficient to pay in full the whole amount so
due and unpaid upon the Securities of such series, then to the payment of such principal and
interest or Yield to Maturity, without preference or priority of principal over interest or Yield
to Maturity, or of interest or Yield to Maturity over principal, or of any installment of interest
over any other installment of interest, or of any Security of such series over any other Security
of such series, ratably to the aggregate of such principal and accrued and unpaid interest or Yield
to Maturity; and

          FOURTH: To the payment of the remainder, if any, to the Issuer or any other Person lawfully
entitled thereto.

     Section 5.04 Suits for Enforcement. In case an Event of Default has occurred, has not been waived
and is continuing, the Trustee may in its discretion proceed to protect and enforce the rights
vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any such rights, either at law or in equity or in bankruptcy
or otherwise, whether for the specific enforcement of any covenant or agreement contained in this
Indenture or in aid of the exercise of any power granted in this Indenture or to enforce any other
legal or equitable right vested in the Trustee by this Indenture or by law.

     Section 5.05 Restoration of Rights on Abandonment of Proceedings. In case the Trustee shall have
proceeded to enforce any right under this Indenture and such proceedings shall have been
discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee,
then and in every such case (subject to any determination in such proceeding) the Issuer and the
Trustee shall be restored respectively to their former positions and rights hereunder, and all
rights, remedies and powers of the Issuer, the Trustee and the Securityholders shall continue as
though no such proceedings had been taken.

     Section 5.06 Limitations on Suits by Securityholders. No Holder of any Security of any series
shall have any right by virtue or by availing of any provision of this Indenture to institute any
action or proceeding at law or in equity or in bankruptcy or otherwise upon or under or with
respect to this Indenture, or for the appointment of a trustee, receiver, liquidator, custodian or
other similar official or for any other remedy hereunder, unless such Holder previously shall have
given to the Trustee written notice of default and of the continuance thereof, as hereinbefore
provided, and unless also the Holders of not less than 25% in aggregate principal amount of the
Securities of such series then Outstanding shall have made written request upon the Trustee to
institute such action or proceedings in its own name as trustee hereunder and shall have offered to
the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities
to be incurred therein or thereby and the Trustee for 60 days after its receipt of such notice,
request and offer of indemnity shall have failed to institute any such

-23-

 

action or proceeding and no direction inconsistent with such written request shall have been given
to the Trustee pursuant to Section 5.09; it being understood and intended, and being expressly
covenanted by the Holder of every Security with every other Holder and the Trustee, that no one or
more Holders of Securities of any series shall have any right in any manner whatever by virtue or
by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any
other such Holder of Securities, or to obtain or seek to obtain priority over or preference to any
other such Holder or to enforce any right under this Indenture, except in the manner herein
provided and for the equal, ratable and common benefit of all Holders of Securities of the
applicable series. For the protection and enforcement of the provisions of this Section, each and
every Securityholder and the Trustee shall be entitled to such relief as can be given either at law
or in equity.

     Section 5.07 Unconditional Right of Securityholders to Institute Certain Suits. Notwithstanding
any other provision in this Indenture and any provision of any Security, the right of any Holder of
any Security to receive payment of the principal of and interest on such Security on or after the
respective due dates expressed in such Security in accordance with the terms hereof and thereof, or
to institute suit for the enforcement of any such payment on or after such respective dates, or for
the enforcement of such conversion right, shall not be impaired or affected without the consent of
such Holder.

     Section 5.08 Powers and Remedies Cumulative; Delay or Omission Not Waiver of Default. Except as
provided in Section 5.06, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders of Securities is intended to be exclusive of any other right or remedy, and every right
and remedy shall, to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise.
The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

     No delay or omission of the Trustee or of any Holder of Securities to exercise any right or
power accruing upon any Event of Default occurring and continuing as aforesaid shall impair any
such right or power or shall be construed to be a waiver of any such Event of Default or an
acquiescence therein; and, subject to Section 5.06, every power and remedy given by this Indenture
or by law to the Trustee or to the Holders of Securities may be exercised from time to time, and as
often as shall be deemed expedient, by the Trustee or by the Holders of Securities.

     Section 5.09 Control by Holders of Securities. The Holders of a majority in aggregate principal
amount of the Securities of each series affected (with each series voting as a separate class) at
the time Outstanding shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee with respect to the Securities of such series by this Indenture; provided, that such
direction shall not be otherwise than in accordance with law and the provisions of this Indenture
and provided, further, that (subject to the provisions of Section 6.01) the Trustee shall have the
right to decline to follow any such direction if the Trustee, being advised by counsel, shall
determine that the action or proceeding so directed may not lawfully be taken or if the Trustee in
good faith by its board of directors, the executive committee, or a trust committee of directors or
Responsible Officers of the Trustee shall determine that the action or

-24-

 

proceedings so directed would involve the Trustee in personal liability or if the Trustee in good
faith shall so determine that the actions or forbearances specified in or pursuant to such
direction would be unduly prejudicial to the interests of Holders of the Securities of all series
so affected not joining in the giving of said direction, it being understood that (subject to
Section 6.01) the Trustee shall have no duty to ascertain whether or not such actions or
forbearances are unduly prejudicial to such Holders.

     Nothing in this Indenture shall impair the right of the Trustee in its discretion to take any
action deemed proper by the Trustee and which is not inconsistent with such direction or directions
by Securityholders.

     Section 5.10 Waiver of Past Defaults. Prior to the declaration of the acceleration of the maturity
of the Securities of any series as provided in Section 5.01, the Holders of a majority in aggregate
principal amount of the Securities of such series at the time Outstanding may on behalf of the
Holders of all the Securities of such series waive any past default in the performance of any of
the covenants contained herein or established pursuant to Section 2.03 with respect to such series
and its consequences, except a default in the payment of the principal of (or premium, if any), or
interest on, any of the Securities of that series as and when the same shall become due by the
terms of such Securities. In the case of any such waiver, the Issuer, the Trustee and the Holders
of the Securities of such series shall be restored to their former positions and rights hereunder,
respectively; but no such waiver shall extend to any subsequent or other default or impair any
right consequent thereon.

     Upon any such waiver, such default shall cease to exist and be deemed to have been cured and
not to have occurred, and any Event of Default arising therefrom shall be deemed to have been
cured, and not to have occurred for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other default or Event of Default or impair any right consequent
thereon.

     Section 5.11 Trustee to Give Notice of Default. The Trustee shall, within 90 days after the
occurrence of a default with respect to the Securities of any series, give notice of all defaults
with respect to that series known to the Trustee to all Holders of Securities of such series in the
manner and to the extent provided in Section 4.03, unless in each case such defaults shall have
been cured before the mailing or publication of such notice (the term “defaults” for the purpose of
this Section being hereby defined to mean any event or condition which is, or with notice or lapse
of time or both would become, an Event of Default); provided, that, except in the case of default
in the payment of the principal of or interest on any of the Securities of such series, or in the
payment of any sinking fund installment on such series, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive committee, or a
trust committee of directors or trustees and/or Responsible Officers of the Trustee in good faith
determines that the withholding of such notice is in the interests of the Securityholders of such
series.

     Section 5.12 Right of Court to Require Filing of Undertaking to Pay Costs. All parties to this
Indenture agree, and each Holder of any Security by his or her acceptance thereof shall be deemed
to have agreed, that any court may in its discretion require, in any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for any

-25-

 

action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit
of an undertaking to pay the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee,
to any suit instituted by any Securityholder or group of Securityholders of any series holding in
the aggregate more than 10% in aggregate principal amount of the Securities of such series, or to
any suit instituted by any Securityholder for the enforcement of the payment of the principal of
(or premium, if any) or interest on any Security of such series, on or after the respective due
dates expressed in such Security or established pursuant to this Indenture.

ARTICLE 6

CONCERNING THE TRUSTEE

     Section 6.01 Duties and Responsibilities of the Trustee; During Default; Prior to Default. With
respect to the Holders of any series of Securities issued hereunder, the Trustee, prior to the
occurrence of an Event of Default with respect to the Securities of a particular series and after
the curing or waiving of all Events of Default which may have occurred with respect to such series,
undertakes to perform such duties and only such duties as are specifically set forth in this
Indenture. In case an Event of Default with respect to the Securities of a series has occurred
(which has not been cured or waived), 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 or her own
affairs.

     No provision of this Indenture shall be construed to relieve the Trustee from liability for
its own negligent action, its own negligent failure to act or its own willful misconduct.

     Section 6.02 Certain Rights of the Trustee. In furtherance of and subject to the Trust Indenture
Act of 1939 and subject to Section 6.01:

          (a) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely,
as to the truth of the statements and the correctness of the opinions expressed therein, upon any
statements, certificates or opinions furnished to the Trustee and conforming to the requirements of
this Indenture; but, in the case of any such statements, certificates or opinions which by any
provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be
under a duty to examine the same to determine whether or not they conform to the requirements of
this Indenture;

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

          (c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by
it in good faith in accordance with the direction of the Holders pursuant to Section 5.09 relating
to the time, method and place of conducting any proceeding for any remedy

-26-

 

available to the Trustee, or exercising any trust or power conferred upon the Trustee, under
this Indenture;

          (d) none of the provisions contained in this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur personal financial liability in the performance of any of its
duties or in the exercise of any of its rights or powers if there shall be reasonable ground for
believing that the repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it;

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

          (f) any request, direction, order or demand of the Issuer mentioned herein shall be
sufficiently evidenced by an Officer’s Certificate (unless other evidence in respect thereof be
herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to
the Trustee by a copy thereof certified by the secretary or an assistant secretary of the Issuer;

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

          (h) the Trustee shall be under no obligation to exercise any of the trusts or powers vested in
it by this Indenture at the request, order or direction of any of the Securityholders pursuant to
the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities which might be
incurred therein or thereby;

          (i) the Trustee shall not be liable for any action taken or omitted by it in good faith and
believed by it to be authorized or within the discretion, rights or powers conferred upon it by
this Indenture;

          (j) prior to the occurrence of an Event of Default hereunder and after the curing or waiving
of all Events of Default, the Trustee shall not be bound to make any investigation into the facts
or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, appraisal, bond, debenture, note, security, or other paper or
document unless requested in writing so to do by the Holders of not less than a majority in
aggregate principal amount of the Securities of all series affected then Outstanding; provided,
that, if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities
likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee,
not reasonably assured to the Trustee by the security afforded to it by the terms of this
Indenture, the Trustee may require reasonable indemnity against such expenses or liabilities as a
condition to proceeding; the reasonable expenses of every such investigation shall

-27-

 

be paid by the Issuer or, if paid by the Trustee or any predecessor trustee, shall be repaid
by the Issuer upon demand; and

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

     Section 6.03 Trustee Not Responsible for Recitals, Disposition of Securities or Application of
Proceeds Thereof. The recitals contained herein and in the Securities, except the Trustee’s
certificates of authentication, shall be taken as the statements of the Issuer, and the Trustee
assumes no responsibility for the correctness of the same. The Trustee makes no representation as
to the validity or sufficiency of this Indenture or of the Securities. The Trustee shall not be
accountable for the use or application by the Issuer of any of the Securities or of the proceeds
thereof.

     Section 6.04 Trustee and Agents May Hold Securities; Collections, Etc. The Trustee or any agent of
the Issuer or the Trustee, in its individual or any other capacity, may become the owner or pledgee
of Securities with the same rights it would have if it were not the Trustee or such agent and may
otherwise deal with the Issuer and receive, collect, hold and retain collections from the Issuer
with the same rights it would have if it were not the Trustee or such agent.

     Section 6.05 Moneys Held by Trustee. Subject to the provisions of Section 10.04 hereof, all moneys
received by the Trustee shall, until used or applied as herein provided, be held in trust for the
purposes for which they were received, but need not be segregated from other funds except to the
extent required by mandatory provisions of law. Neither the Trustee nor any agent of the Issuer or
the Trustee shall be under any liability for interest on any moneys received by it hereunder.

     Section 6.06 Compensation and Indemnification of Trustee and Its Prior Claim. The Issuer covenants
and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such
reasonable compensation (which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust) as the Issuer and the Trustee may from time to time
agree in writing and, except as otherwise expressly provided herein, the Issuer covenants and
agrees to pay or reimburse the Trustee and each predecessor trustee upon its request for all
reasonable expenses, disbursements and advances incurred or made by or on behalf of it in
accordance with any of the provisions of this Indenture (including the reasonable compensation and
the expenses and disbursements of its counsel and of all agents and other persons not regularly in
its employ) except any such expense, disbursement or advance as may arise from its negligence or
bad faith. The Issuer also covenants to indemnify the Trustee and each predecessor trustee for,
and to hold it harmless against, any loss, liability or expense incurred without negligence or bad
faith on its part, arising out of or in connection with the acceptance or administration of this
Indenture or the trusts hereunder and its duties hereunder, including the costs and expenses of
defending itself against or investigating any claim of liability in the premises. The obligations
of the Issuer under this Section to compensate and indemnify the Trustee and each predecessor
trustee and to pay or reimburse the Trustee and each

-28-

 

predecessor trustee for expenses, disbursements and advances shall constitute additional
indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture. Such
additional indebtedness shall be a senior claim to that of the Securities upon all property and
funds held or collected by the Trustee as such, except funds held in trust for the benefit of the
Holders of particular Securities, and the Securities are hereby subordinated to such senior claim.

     Section 6.07 Right of Trustee to Rely on Officer’s Certificate, Etc. Subject to Sections 6.01 and
6.02, whenever in the administration of the trusts of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or suffering or
omitting any action hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee,
be deemed to be conclusively proved and established by an Officer’s Certificate delivered to the
Trustee, and such certificate, in the absence of negligence or bad faith on the part of the
Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under
the provisions of this Indenture upon the faith thereof.

     Section 6.08 Disqualification; Conflicting Interests. If the Trustee has or shall acquire any
“conflicting interest” within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee
and the Issuer shall in all respects comply with the provisions of Section 310(b) of the Trust
Indenture Act.

     Section 6.09 Persons Eligible for Appointment as Trustee. The Trustee for each series of
Securities hereunder shall at all times be a corporation having a combined capital and surplus of
at least $50,000,000 and shall be eligible in accordance with the provisions of Section 310(a) of
the Trust Indenture Act of 1939. If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of a Federal, State or District of Columbia
supervising or examining authority, then, for the purposes of this Section, the combined capital
and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published.

     Section 6.10 Resignation and Removal; Appointment of Successor Trustee. (a) The Trustee, or any
trustee or trustees hereafter appointed, may at any time resign with respect to one or more or all
series of Securities by giving written notice of resignation to the Issuer and by mailing notice of
such resignation to the Holders of then Outstanding Securities of each series affected at their
addresses as they shall appear on the Security register. Upon receiving such notice of
resignation, the Issuer shall promptly appoint a successor trustee or trustees with respect to the
applicable series by written instrument in duplicate, executed by authority of the Board of
Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to
the successor trustee or trustees. If no successor trustee shall have been so appointed with
respect to any series and have accepted appointment within 30 days after the mailing of such notice
of resignation, the resigning trustee may petition any court of competent jurisdiction for the
appointment of a successor trustee, or any Securityholder who has been a bona fide Holder of a
Security or Securities of the applicable series for at least six months may, on behalf of himself
or herself and all others similarly situated, petition any such court for the appointment of a
successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and
prescribe, appoint a successor trustee.

-29-

 

          (b) In case at any time any of the following shall occur:

     (i) the Trustee shall fail to comply with the provisions of Section 310(b) of
the Trust Indenture Act of 1939 with respect to any series of Securities after
written request therefor by the Issuer or by any Securityholder who has been a bona
fide Holder of a Security or Securities of such series for at least six months; or

     (ii) the Trustee shall cease to be eligible in accordance with the provisions
of Section 310(a) of the Trust Indenture Act of 1939 and shall fail to resign after
written request therefor by the Issuer or by any Securityholder; or

     (iii) the Trustee shall become incapable of acting with respect to any series
of Securities, or shall be adjudged bankrupt or insolvent, or a receiver or
liquidator of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or affairs
for the purpose of rehabilitation, conservation or liquidation;

then, in any such case, (A) the Issuer may remove the Trustee with respect to the applicable series
of Securities and appoint a successor trustee for such series by written instrument, in duplicate,
executed by order of the Board of Directors, one copy of which instrument shall be delivered to the
Trustee so removed and one copy to the successor trustee, or, (B) subject to Section 315(e) of the
Trust Indenture Act of 1939, any Securityholder who has been a bona fide Holder of a Security or
Securities of such series for at least six months may on behalf of himself or herself and all
others similarly situated, petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor trustee with respect to such series. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and
appoint a successor trustee.

          (c) The Holders of a majority in aggregate principal amount of the Securities of each series
at the time Outstanding may at any time remove the Trustee with respect to Securities of such
series and, with the consent of the Issuer, appoint a successor trustee with respect to the
Securities of such series by delivering to the Trustee so removed, to the successor trustee so
appointed and to the Issuer the evidence provided for in Section 7.01 of the action in that regard
taken by the Securityholders.

          (d) Any resignation or removal of the Trustee with respect to any series and any appointment
of a successor trustee with respect to such series pursuant to any of the provisions of this
Section 6.10 shall become effective upon acceptance of appointment by the successor trustee as
provided in Section 6.11.

     Section 6.11 Acceptance of Appointment by Successor Trustee. Any successor trustee appointed as
provided in Section 6.10 shall execute and deliver to the Issuer and to its predecessor trustee an
instrument accepting such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee with respect to all or any applicable series shall become effective and such
successor trustee, without any further act, deed or conveyance, shall become vested with all
rights, powers, duties and obligations with respect to such series of its

-30-

 

predecessor hereunder, with like effect as if originally named as trustee for such series
hereunder; but, nevertheless, on the written request of the Issuer or of the successor trustee,
upon payment of its charges then unpaid, the trustee ceasing to act shall, subject to Section
10.04, pay over to the successor trustee all moneys at the time held by it hereunder and shall
execute and deliver an instrument transferring to such successor trustee all such rights, powers,
duties and obligations. Upon request of any such successor trustee, the Issuer shall execute any
and all instruments in writing for more fully and certainly vesting in and confirming to such
successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless,
retain a prior claim upon all property or funds held or collected by such trustee to secure any
amounts then due it pursuant to the provisions of Section 6.06.

     If a successor trustee is appointed with respect to the Securities of one or more (but not
all) series, the Issuer, the predecessor trustee and each successor trustee with respect to the
Securities of any applicable series shall execute and deliver an indenture supplemental hereto
which shall contain such provisions as shall be deemed necessary or desirable to confirm that all
the rights, powers, trusts and duties of the predecessor trustee with respect to the Securities of
any series as to which the predecessor trustee is not retiring shall continue to be vested in the
predecessor trustee, and shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts hereunder by more than one
trustee, it being understood that nothing herein or in such supplemental indenture shall constitute
such trustees co-trustees of the same trust and that each such trustee shall be trustee of a trust
or trusts under separate indentures.

     No successor trustee with respect to any series of Securities shall accept appointment as
provided in this Section 6.11 unless at the time of such acceptance such successor trustee shall be
qualified under the provisions of Section 310(b) of the Trust Indenture Act of 1939 and eligible
under the provisions of Section 310(a) of the Trust Indenture Act of 1939.

     Upon acceptance of appointment by any successor trustee as provided in this Section 6.11, the
Issuer shall mail notice thereof to the Holders of Securities of each series affected, by mailing
such notice to such Holders at their addresses as they shall appear on the Security register. If
the acceptance of appointment is substantially contemporaneous with the resignation, then the
notice called for by the preceding sentence may be combined with the notice called for by Section
6.10. If the Issuer fails to mail such notice within ten days after acceptance of appointment by
the successor trustee, the successor trustee shall cause such notice to be given at the expense of
the Issuer.

     Section 6.12 Merger, Conversion, Consolidation or Succession to Business of Trustee. Any
corporation into which the Trustee may be merged or converted or with which it may be consolidated,
or any corporation resulting from any merger, conversion or consolidation to which the Trustee
shall be a party, or any corporation succeeding to the corporate trust business of the Trustee,
shall be the successor of the Trustee hereunder; provided, that such corporation shall be qualified
under the provisions of Section 310(b) of the Trust Indenture Act of 1939 and eligible under the
provisions of Section 310(a) of the Trust Indenture Act of 1939, without the execution or filing of
any paper or any further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding.

-31-

 

     In case, at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture, any of the Securities of any series shall have been authenticated but not delivered, any
such successor to the Trustee may adopt the certificate of authentication of any predecessor
trustee and deliver such Securities so authenticated; and, in case at that time any of the
Securities of any series shall not have been authenticated, any successor to the Trustee may
authenticate such Securities either in the name of any predecessor hereunder or in the name of the
successor trustee; and in all such cases such certificate shall have the full force which it is
anywhere in the Securities of such series or in this Indenture provided that the certificate of the
Trustee shall have; provided, that the right to adopt the certificate of authentication of any
predecessor trustee or to authenticate Securities of any series in the name of any predecessor
trustee shall apply only to its successor or successors by merger, conversion or consolidation.

     Section 6.13 Preferential Collection of Claims Against the Issuer. The Trustee shall comply with
Section 311(a) of the Trust Indenture Act, excluding any creditor relationship described in Section
311(b) of the Trust Indenture Act. A Trustee who has resigned or been removed shall be subject to
Section 311(a) of the Trust Indenture Act to the extent included therein.

ARTICLE 7

CONCERNING THE SECURITYHOLDERS

     Section 7.01 Evidence of Action Taken by Securityholders. Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to be given or taken
by a specified percentage in principal amount of the Securityholders of any or all series may be
embodied in and evidenced by one or more instruments of substantially similar tenor signed by such
specified percentage of Securityholders in person or by agent duly appointed in writing; and,
except as herein otherwise expressly provided, such action shall become effective when such
instrument or instruments are delivered to the Trustee. Proof of execution of any instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this Indenture and
(subject to Sections 6.01 and 6.02) conclusive in favor of the Trustee and the Issuer, if made in
the manner provided in this Article.

     Section 7.02 Proof of Execution of Instruments and of Holding of Securities. Subject to Sections
6.01 and 6.02, the execution of any instrument by a Holder or his agent or proxy may be proved in
accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in
such manner as shall be satisfactory to the Trustee. The holding of Securities shall be proved by
the Security register or by a certificate of the registrar thereof. The Issuer may set a record
date for purposes of determining the identity of Holders of any series entitled to vote or consent
to any action referred to in Section 7.01, which record date may be set at any time or from time to
time by notice to the Trustee, for any date or dates (in the case of any adjournment or
reconsideration) not more than 60 days nor less than five days prior to the proposed date of such
vote or consent, and thereafter, notwithstanding any other provisions hereof, only Holders of such
series of record on such record date shall be entitled to so vote or give such consent or revoke
such vote or consent. Notice of such record date may be given before or after any request for any
action referred to in Section 7.01 is made by the Issuer.

-32-

 

     Section 7.03 Holders to Be Treated as Owners. The Issuer, the Trustee and any agent of the Issuer
or of the Trustee may deem and treat the Person in whose name any Security shall be registered upon
the Security register for such series as the absolute owner of such Security (whether or not such
Security shall be overdue and notwithstanding any notation of ownership or other writing thereon)
for the purpose of receiving payment of or on account of the principal of, and, subject to the
provisions of this Indenture, interest on, such Security and for all other purposes; and neither
the Issuer nor the Trustee nor any agent of the Issuer or the Trustee shall be affected by any
notice to the contrary. All such payments so made to any such Person, or upon his or her order,
shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge
the liability for moneys payable.

     Section 7.04 Securities Owned by Issuer Deemed Not Outstanding. In determining whether the Holders
of the requisite aggregate principal amount of Outstanding Securities of any or all series have
concurred in any direction, consent or waiver under this Indenture, Securities which are owned by
the Issuer or any other obligor on the Securities with respect to which such determination is being
made or by any Person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Issuer or any other obligor on the Securities with respect to
which such determination is being made shall be disregarded and deemed not to be Outstanding for
the purpose of any such determination, except that, for the purpose of determining whether the
Trustee shall be protected in relying on any such direction, consent or waiver, only Securities
which the Trustee knows are so owned shall be so disregarded. Securities so owned which have been
pledged in good faith may be regarded as Outstanding if the pledgee establishes to the satisfaction
of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee
is not the Issuer or any other obligor upon the Securities or any Person directly or indirectly
controlling or controlled by or under direct or indirect common control with the Issuer or any
other obligor on the Securities. In case of a dispute as to such right, the advice of counsel
shall be full protection in respect of any decision made by the Trustee in accordance with such
advice.

     Section 7.05 Right of Revocation of Action Taken. At any time prior to (but not after) the
evidencing to the Trustee, as provided in Section 7.01, of the taking of any action by the Holders
of the percentage in aggregate principal amount of the Securities of any or all series, as the case
may be, specified in this Indenture in connection with such action, any Holder of a Security the
serial number of which is shown by the evidence to be included among the serial numbers of the
Securities the Holders of which have consented to such action may, by filing written notice at the
Corporate Trust Office and upon proof of holding as provided in this Article, revoke such action so
far as concerns such Security. Except as aforesaid, any such action taken by the Holder of any
Security shall be conclusive and binding upon such Holder and upon all future Holders and owners of
such Security and of any Securities issued in exchange or substitution therefor or on registration
of transfer thereof, irrespective of whether or not any notation in regard thereto is made upon any
such Security. Any action taken by the Holders of the percentage in aggregate principal amount of
the Securities of any or all series, as the case may be, specified in this Indenture in connection
with such action shall be conclusively binding upon the Issuer, the Trustee and the Holders of all
the Securities affected by such action.

ARTICLE 8

SUPPLEMENTAL INDENTURES

     Section 8.01 Supplemental Indentures Without Consent of Securityholders. The Issuer, when
authorized by a resolution of its Board of Directors, and the Trustee may from time to time and at
any time enter into an indenture or indentures supplemental hereto in form satisfactory to the
Trustee for one or more of the following purposes:

          (a) to convey, transfer, assign, mortgage or pledge to the Trustee as security for the
Securities of one or more series any property or assets;

          (b) to evidence the succession of another corporation to the Issuer, or successive
successions, and the assumption by the successor corporation of the covenants, agreements and
obligations of the Issuer pursuant to Article 9;

          (c) to add to the covenants of the Issuer such further covenants, restrictions, conditions or
provisions as its Board of Directors and the Trustee shall consider to be for the protection of the
Holders of Securities, and to make the occurrence, or the occurrence and continuance, of a default
in any such additional covenants, restrictions, conditions or provisions an Event of Default
permitting the enforcement of all or any of the several remedies provided in this Indenture as
herein set forth; provided, that in respect of any such additional covenant, restriction, condition
or provision such supplemental indenture may provide for a particular period of grace after default
(which period may be shorter or longer than that allowed in the case of other defaults) or may
provide for an immediate enforcement upon such an Event of Default or may limit the remedies
available to the Trustee upon such an Event of Default or may limit the right of the Holders of a
majority in aggregate principal amount of the Securities of such series to waive such an Event of
Default;

          (d) to cure any ambiguity or to correct or supplement any provision contained herein or in any
supplemental indenture which may be defective or inconsistent with any other provision contained
herein or in any supplemental indenture, or to conform this Indenture or any supplemental indenture
to the description of the Securities set forth in any prospectus or prospectus supplement related
to such series of Securities;

          (e) to provide for or add guarantors for the Securities of one or more series;

          (f) to establish the form or terms of Securities of any series as permitted by Sections 2.01
and 2.03;

          (g) to evidence and provide for the acceptance of appointment hereunder by a successor trustee
with respect to the Securities of one or more series and to 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, pursuant to the requirements of Section 6.11;

          (h) to add to, delete from or revise the conditions, limitations and restrictions on the
authorized amount, terms, purposes of issue, authentication and delivery of any series of
Securities, as herein set forth;

-34-

 

          (i) to make any change to the Securities of any series so long as no Securities of such series
are Outstanding; and

          (j) to make any other change that does not adversely affect the interests of the Holders of
the Securities in any material respect.

     The Trustee is hereby authorized to join with the Issuer in the execution of any such
supplemental indenture, to make any further appropriate agreements and stipulations which may be
therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any
property thereunder, but the Trustee shall not be obligated to enter into any such supplemental
indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or
otherwise.

     Any supplemental indenture authorized by the provisions of this Section may be executed
without the consent of the Holders of any of the Securities at the time Outstanding,
notwithstanding any of the provisions of Section 8.02.

     Section 8.02 Supplemental Indentures With Consent of Securityholders. With the consent (evidenced
as provided in Article 7) of the Holders of not less than a majority in aggregate principal amount
of the Securities at the time Outstanding of all series affected by such supplemental indenture
(voting as one class), the Issuer, when authorized by a resolution of the Board of Directors, and
the Trustee may, from time to time and at any time, enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture or of any supplemental indenture or of
modifying in any manner the rights of the Holders of the Securities of each such series; provided,
that no such supplemental indenture shall, without the consent of the Holder of each Security so
affected, (a) extend the final maturity of any Security, or reduce the principal amount thereof, or
reduce the rate or extend the time of payment of interest thereon, or reduce any amount payable on
redemption thereof, or make the principal thereof (including any amount in respect of original
issue discount) or interest thereon payable in any currency other than that provided in the
Securities or in accordance with the terms thereof, or reduce the amount of the principal of an
Original Issue Discount Security that would be due and payable upon an acceleration of the maturity
thereof pursuant to Section 5.01 or the amount thereof provable in bankruptcy pursuant to Section
5.02, or waive a default in the payment of principal of any Security or interest thereon or change
a provision related to the waiver of past defaults or changes or impair the right of any
Securityholder to institute suit for the payment or conversion thereof or, if the Securities
provide therefor, any right of repayment at the option of the Securityholder, (b) modify any of the
provisions of this section except to increase any required percentage or to provide that certain
other provisions cannot be modified or waived without the consent of the Holder of each Security so
affected, or (c) reduce the aforesaid percentage of Securities of any series, the consent of the
Holders of which is required for any such supplemental indenture or the consent of Holders of which
is required for any modification, amendment or waiver of compliance with certain provisions of this
Indenture or certain defaults hereunder and their consequences provided for in this Indenture.

     A supplemental indenture which changes or eliminates any covenant, Event of Default or other
provision of this Indenture (1) that has been expressly included solely for the benefit of one

-35-

 

or more particular series of Securities, if any, or (2) which modifies the rights of Holders
of Securities of one or more series with respect to any covenant, Event of Default or provision,
shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any
other series with respect to which such covenant, Event of Default or other provision has not been
modified.

     Upon the request of the Issuer, accompanied by a Board Resolution authorizing the execution of
any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of
Securityholders as aforesaid and other documents, if any, required by Section 7.01, the Trustee
shall join with the Issuer in the execution of such supplemental indenture unless such supplemental
indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise,
in which case the Trustee may in its discretion, but shall not be obligated to, enter into such
supplemental indenture.

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

     Promptly after the execution by the Issuer and the Trustee of any supplemental indenture
pursuant to the provisions of this Section, the Trustee shall give a notice thereof to the Holders
of then Outstanding Securities of each series affected thereby, by mailing a notice thereof by
first-class mail to such Holders at their addresses as they shall appear on the Security register,
and in each case such notice shall set forth in general terms the substance of such supplemental
indenture. Any failure of the Trustee to mail such notice, or any defect therein, shall not,

any Person, unless (a) the Person formed by such consolidation or into which the Issuer is merged
or the Person which acquires by conveyance or transfer, or which leases, the properties and assets
of the Issuer substantially as an entirety (i) shall be a corporation, limited liability company,
partnership or trust, (ii) shall be organized and validly existing under the laws of the United

the Issuer to be performed, by supplemental indenture satisfactory in form to the Trustee, executed
and delivered to the Trustee, by the Person formed by such consolidation or into which the Issuer
shall have been merged or by the Person which shall have acquired the Issuer’s assets; (b)
immediately after giving effect to such transaction and treating any indebtedness which becomes an
obligation of the Issuer or any Subsidiary as a result of such transaction as having been incurred
by the Issuer or such Subsidiary at the time of such transaction, no Event of Default, and no event
which, after notice or lapse of time or both, would become an Event of Default, shall have happened
and be continuing; and (c) the Issuer has delivered to the Trustee an Officer’s Certificate and an
Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer or lease
and, if a supplemental indenture is required in connection with such transaction, such supplemental
indenture comply with this Article and that all conditions precedent herein provided for relating
to such transaction have been complied with.

     The conditions of (a)(ii) above shall not apply in the case of a corporation or entity not

purpose of such transaction is principally to change the Issuer’s State of incorporation or convert
the Issuer’s form of organization to another form, or (ii) the merger of the Issuer with or into a

-37-

 

single direct or indirect wholly owned Subsidiary pursuant to Section 251(g) (or any
successor provision) of the General Corporation Law of the State of Delaware.

     Nothing contained in this Article shall apply to, limit or impose any requirements upon the
consolidation or merger of any Person into the Issuer where the Issuer is the survivor of such
transaction, or the acquisition by the Issuer, by purchase or otherwise, of all or any part of the
property of any other Person (whether or not affiliated with the Issuer).

     Section 9.02 Successor Issuer Substituted. Upon any consolidation of the Issuer with, or merger of
the Issuer into, any other Person or any conveyance, transfer or lease of the properties and assets
of the Issuer substantially as an entirety in accordance with Section 9.01, the successor Person
formed by such consolidation or into which the Issuer is merged or to which such conveyance,
transfer or lease is made shall succeed to, and be substituted for, and may exercise every right
and power of, the Issuer under this Indenture with the same effect as if such successor Person had
been named as the Issuer herein, and thereafter, except in the case of a lease, the predecessor
Person shall be relieved of all obligations and covenants under this Indenture and the Securities.

     In case of any such consolidation, merger, sale, lease or conveyance, such changes in
phraseology and form (but not in substance) may be made in the Securities thereafter to be issued
as may be appropriate.

Certificate and an Opinion of Counsel which complies with Section 11.05 and at the cost and expense
of the Issuer, shall execute proper instruments acknowledging such satisfaction of and discharging
this Indenture with respect to such series. The Issuer agrees to reimburse the Trustee for any
costs or expenses thereafter reasonably and properly incurred and to compensate the Trustee for any

          (b) The following subsection shall apply to the Securities of each series unless specifically
otherwise provided in a Board Resolution, Officer’s Certificate or indenture supplemental hereto

Securities of a series (“Legal Defeasance”), such discharge to be effective on the date that the
conditions set forth in clauses (i) through (iii), (iv) and (vi) of Section 10.01(d) are satisfied,
and thereafter the Issuer shall be deemed to have paid and discharged the entire Debt on all the
Securities of such a series, and satisfied all its other obligations under such Securities

-39-

 

and this Indenture insofar as such Securities are concerned and this Indenture shall cease to
be of further effect with respect to Securities of such series (except as to (1) rights of
registration of transfer, conversion and exchange of Securities of such series, (2) substitution of
apparently mutilated, defaced, destroyed, lost or stolen Securities, (3) rights of Holders of
Securities to receive, solely from the trust fund described in Section 10.01(d)(i), payments of

with respect to the Securities of such series under Sections 10.02 and 10.04 and (5) the
obligations of the Issuer under Section 3.02).

          (c) The following subsection shall apply to the Securities of each series unless specifically
otherwise provided in a Board Resolution, Officer’s Certificate or indenture supplemental hereto
provided pursuant to Section 2.03. In addition to discharge of the Indenture pursuant to
subsection (a) and Legal Defeasance pursuant to subsection (b), above, the Issuer, at its option
and at any time, by written notice executed by an officer delivered to the Trustee, may elect to
have its obligations under any covenant contained in the Board Resolution or supplemental indenture
relating to such series pursuant to Section 2.03 discharged with respect to all Outstanding
Securities of a series, this Indenture and any indentures supplemental to this Indenture insofar as
such Securities are concerned (“Covenant Defeasance”), such discharge to be effective on the date
the conditions set forth in clauses (i) through (iii) and (v) through (vi) of Section 10.01(d) are
satisfied, and such Securities shall thereafter be deemed to be not “Outstanding” for the purposes
of any direction, waiver, consent or declaration of Securityholders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be “Outstanding” for all other
purposes under this Indenture. For this purpose, such covenant defeasance means that, with respect
to the Outstanding Securities of a series, the Issuer may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such covenant, whether
directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by
reason of reference in any such covenant to any other provision herein or in any other document and
such omission to comply shall not constitute an Event of Default under Section 5.01(c) or
otherwise, but except as specified in this Section 10.01(c), the remainder of the Issuer’s
obligations under the Securities of such series, this Indenture, and any indentures supplemental to
this Indenture with respect to such series shall be unaffected thereby.

          (d) The following shall be the conditions to the application of Legal Defeasance under
subsection (b) or Covenant Defeasance under subsection (c) to the Securities of the applicable
series:

     (i) the Issuer irrevocably deposits in trust with the Trustee or, at the option
of the Trustee, with a trustee satisfactory to the Trustee and the Company under the
terms of an irrevocable trust agreement in form and substance satisfactory to the
Trustee, cash or U.S. Government Obligations that will generate cash sufficient to
pay principal of, premium, if any, and interest on the Outstanding Securities of
such series to maturity or redemption, as the case may be, and to pay all other
amounts payable by it hereunder, provided that (A) the

-40-

 

trustee of the irrevocable trust, if any, shall have been irrevocably
instructed to pay such funds or the proceeds of such U.S. Government Obligations to
the Trustee and (B) the Trustee shall have been irrevocably instructed to apply such
funds or the proceeds of such U.S. Government Obligations to (x) the principal and
interest on all Securities of such series on the date that such principal or
interest is due and payable and (y) any mandatory sinking fund payments on the day
on which such payments are due and payable in accordance with the terms of the
Indenture and the Securities of such series, and the Issuer shall also pay or cause
to be paid all other amounts payable hereunder with respect to such series;

     (ii) the Issuer delivers to the Trustee an Officer’s Certificate stating that
all conditions precedent specified herein relating to Legal Defeasance or Covenant
Defeasance, as the case may be, have been complied with, and an Opinion of Counsel

shall have occurred and be continuing, and no event which with notice or lapse of
time or both would become such an Event of Default shall have occurred and be
continuing, on the date of such deposit;

     (iv) in the event of an election for Legal Defeasance under subsection (b), the
Issuer shall have delivered to the Trustee an Opinion of Counsel stating that (A)
the Issuer has received from, or there has been published by, the Internal Revenue
Service a ruling or (B) since the date of this instrument, there has been a change
in the applicable Federal income tax law, in either case (A) or (B) to the effect
that, and based thereon such opinion shall confirm that, the Holders of such
Securities will not recognize gain or loss for Federal income tax purposes as a
result of the deposit, defeasance and discharge to be effected with respect to such
Securities and will be subject to Federal income tax on the same amounts, in the
same manner and at the same times as would be the case if such deposit, defeasance
and discharge were not to occur;

     (v) in the event of an election for Covenant Defeasance under subsection (c),
the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect
that the Holders of such Securities will not recognize gain or loss for Federal
income tax purposes as a result of the deposit and Covenant Defeasance to be
effected with respect to such Securities and will be subject to Federal income tax
on the same amount, in the same manner and at the same times as would be the case if
such deposit and Covenant Defeasance were not to occur; and

     (vi) notwithstanding any other provisions of this subsection (d), such
defeasance shall be effected in compliance with any additional or substitute terms,
conditions or limitations which may be imposed on the Issuer pursuant to Section
2.03.

conditions set forth in this subsection (d), the Trustee upon request shall execute proper
instruments acknowledging the discharge of the Issuer’s obligations pursuant to this Section 10.01.

     Section 10.02 Application by Trustee of Funds Deposited for Payment of Securities. Subject to
Section 10.04, all moneys deposited with the Trustee (or other trustee) pursuant to Section 10.01
shall be held in trust and applied by it to the payment, either directly or through any paying
agent (including the Issuer acting as its own paying agent), to the Holders of the particular
Securities of such series for the payment or redemption of which such moneys have been deposited
with the Trustee, of all sums due and to become due thereon for principal and interest; but such
money need not be segregated from other funds except to the extent required by law.

     Section 10.03 Repayment of Moneys Held by Paying Agent. In connection with the satisfaction and
discharge of this Indenture with respect to Securities of any series, all moneys then held by any
paying agent under the provisions of this Indenture with respect to such series of Securities
shall, upon demand of the Issuer, be repaid to it or paid to the Trustee and thereupon such paying
agent shall be released from all further liability with respect to such moneys.

     Section 10.04 Return of Moneys Held by Trustee and Paying Agent Unclaimed for Two Years. Any
moneys deposited with or paid to the Trustee or any paying agent for the payment of the principal
of or interest on any Security of any series and not applied but remaining unclaimed for two years
after the date upon which such principal or interest shall have become due and payable, shall be
repaid to the Issuer by the Trustee for such series or such paying agent, and the Holder of the
Securities of such series shall thereafter look only to the Issuer for any payment which such
Holder may be entitled to collect, and all liability of the Trustee or any paying agent with
respect to such moneys shall thereupon cease.

     Section 10.05 Indemnity for U.S. Government Obligations. The Issuer shall pay and indemnify the
Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government
Obligations deposited pursuant to Section 10.01 or the principal or interest received in respect of
such obligations.

Issuer or any such predecessor or successor corporation, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being
expressly understood that this Indenture and the obligations issued hereunder are solely corporate
obligations, and that no such personal liability whatever shall attach to, or is or shall be
incurred by, the incorporators, stockholders, officers or directors as

-42-

 

such, of the Issuer or of any predecessor or successor corporation, or any of them, because of the
creation of the indebtedness hereby authorized, or under or by reason of the obligations, covenants
or agreements contained in this Indenture or in any of the Securities or implied therefrom; and
that any and all such personal liability of every name and nature, either at common law or in
equity or by constitution or statute, of, and any and all such rights and claims against, every
such incorporator, stockholder, officer or director as such, because of the creation of the
indebtedness hereby authorized, or under or by reason of the obligations, covenants or agreements
contained in this Indenture or in any of the Securities or implied therefrom, are hereby expressly
waived and released as a condition of, and as a consideration for, the execution of this Indenture
and the issuance of such Securities.

     Section 11.02 Provisions of Indenture for the Sole Benefit of Parties and Holders of Securities.
Nothing in this Indenture or in the Securities, expressed or implied, shall give or be construed to
give to any person, firm or corporation, other than the parties hereto and their successors and the
Holders of the Securities any legal or equitable right, remedy or claim under this Indenture or
under any covenant or provision herein contained, all such covenants and provisions being for the
sole benefit of the parties hereto and their successors and of the Holders of the Securities.

     Section 11.03 Successors and Assigns of Issuer Bound by Indenture. All the covenants,
stipulations, promises and agreements contained in this Indenture by or on behalf of the Issuer

impracticable to mail notice to the Issuer when such notice is required to be given pursuant to any
provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the

other Holders of Securities given as provided above.

by the Person entitled to receive such notice either before or after the event, and such waiver
shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

     Section 11.05 Officer’s Certificates and Opinions of Counsel; Statements to Be Contained Therein.
Upon any application or demand by the Issuer to the Trustee to take any action under any of the

statement or opinion of counsel may be based, insofar as it relates to factual matters, information
with respect to which is in the possession of the Issuer, upon the certificate, statement or
opinion of or representations by an officer or officers of the Issuer, unless such counsel knows

on or principal of the Securities of any series or the date fixed for redemption or repayment of
any such Security, or the last day on which a Holder has the right to convert any Security, shall
not be a Business Day, then payment of interest or principal, or any conversion, need not be made
on such date, but may be made on the next succeeding Business Day with the same force and effect as
if made on the date of maturity or the date fixed for redemption or on such last day for
conversion, and no interest shall accrue for the period after such date.

lawful successor of the Issuer.

or in the Securities of any series shall for any reason be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any

REDEMPTION OF SECURITIES AND SINKING FUNDS

     Section 12.01 Applicability of Article. The provisions of this Article shall be applicable to the

notice to the Holder of any Security of a series designated for redemption as a whole or in part
shall not affect the validity of the proceedings for the redemption of any other Security of such
series.

     The notice of redemption to each such Holder shall specify the principal amount of each
Security of such series held by such Holder to be redeemed, the date fixed for redemption, the
redemption price, the place or places of payment, that payment will be made upon presentation and
surrender of such Securities, that such redemption is pursuant to the mandatory or optional sinking
fund, or both, if such be the case, that interest accrued to the date fixed for redemption will be
paid as specified in such notice and that on and after said date interest thereon or on the
portions thereof to be redeemed will cease to accrue and shall also specify, if applicable, the
conversion price then in effect and the date on which the right to convert such Securities or the
portions thereof to be redeemed will expire. In case any Security of a series is to be redeemed in
part only, the notice of redemption shall state the portion of the principal amount thereof to be
redeemed and shall state that on and after the date fixed for redemption, upon surrender of such
Security, a new Security or Securities of such series in principal amount equal to the unredeemed
portion thereof will be issued.

     The notice of redemption of Securities of any series to be redeemed at the option of the
Issuer shall be given by the Issuer or, at the Issuer’s request, by the Trustee in the name and at
the expense of the Issuer.

     On or before the redemption date specified in the notice of redemption given as provided in
this Section, the Issuer will deposit with the Trustee or with one or more paying agents (or, if
the Issuer is acting as its own paying agent, set aside, segregate and hold in trust as provided in
Section 3.04) an amount of money sufficient to redeem on the redemption date all the Securities of
such series so called for redemption (other than those theretofore surrendered for conversion into
Common Stock) at the appropriate redemption price, together with accrued interest to the date fixed
for redemption. If any Security called for redemption is converted pursuant hereto,

-46-

 

any money deposited with the Trustee or any paying agent or so segregated and held in trust
for the redemption of such Security shall be paid to the Issuer upon the Issuer’s request, or, if
then held by the Issuer, shall be discharged from such trust. The Issuer will deliver to the
Trustee at least 10 days prior to the date the notice required to be delivered to the Holders is to
be sent (unless a shorter time period shall be acceptable to the Trustee) an Officer’s Certificate
(which need not comply with Section 11.05) stating the aggregate principal amount of Securities to
be redeemed. In case of a redemption at the election of the Issuer prior to the expiration of any
restriction on such redemption, the Issuer shall deliver to the Trustee, prior to the giving of any
notice of redemption to Holders pursuant to this Section, an Officer’s Certificate stating that
such restriction has been complied with.

     If less than all the Securities of a series are to be redeemed, the Trustee shall select, in
such manner as it shall deem appropriate and fair, Securities of such series to be redeemed in
whole or in part. Securities may be redeemed in part in multiples equal to the minimum authorized
denomination for Securities of such series or any multiple thereof. The Trustee shall promptly
notify the Issuer in writing of the Securities of such series selected for redemption and, in the
case of any Securities of such series selected for partial redemption, the principal amount thereof
to be redeemed. For all purposes of this Indenture, unless the context otherwise requires, all
provisions relating to the redemption of Securities of any series shall relate, in the case of any
Security redeemed or to be redeemed only in part, to the portion of the principal amount of such
Security which has been or is to be redeemed. If any Security selected for partial redemption is
surrendered for conversion after such selection, the converted portion of such Security shall be
deemed (so far as may be) to be the portion selected for redemption.

     Section 12.03 Payment of Securities Called for Redemption. If notice of redemption has been given
as above provided, the Securities or portions of Securities specified in such notice shall become
due and payable on the date and at the place stated in such notice at the applicable redemption
price, together with interest accrued to the date fixed for redemption, and on and after said date
(unless the Issuer shall default in the payment of such Securities at the redemption price,
together with interest accrued to said date) interest on the Securities or portions of Securities
so called for redemption shall cease to accrue, and, except as provided in Sections 6.05 and 10.04
or in the paragraph below, such Securities shall cease from and after the date fixed for redemption
to be convertible into Common Stock, if applicable, and cease to be entitled to any benefit or
security under this Indenture, and the Holders thereof shall have no right in respect of such
Securities except the right to receive the redemption price thereof and unpaid interest to the date
fixed for redemption. On presentation and surrender of such Securities at a place of payment
specified in said notice, said Securities or the specified portions thereof shall be paid and
redeemed by the Issuer at the applicable redemption price, together with interest accrued thereon
to the date fixed for redemption; provided, that payment of interest becoming due on or prior to
the date fixed for redemption shall be payable to the Holders of such Securities registered as such
on the relevant record date subject to the terms and provisions of Sections 2.03 and 2.07 hereof.

     If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal shall, until paid or duly provided for, bear interest from the date fixed
for redemption at the rate of interest or Yield to Maturity (in the case of an Original Issue
Discount Security) borne by such Security and, if applicable, such Security shall remain

-47-

 

convertible into Common Stock until the principal of such Security shall have been paid or
duly provided for.

     Upon presentation of any Security redeemed in part only, the Issuer shall execute and the
Trustee shall authenticate and deliver to or on the order of the Holder thereof, at the expense of
the Issuer, a new Security or Securities of such series, of authorized denominations, in principal
amount equal to the unredeemed portion of the Security so presented.

     Section 12.04 Exclusion of Certain Securities from Eligibility for Selection for Redemption.
Securities shall be excluded from eligibility for selection for redemption if they are identified
by registration and certificate number in an Officer’s Certificate delivered to the Trustee at
least 40 days prior to the last date on which notice of redemption may be given as being owned of
record and beneficially by, and not pledged or hypothecated by either (a) the Issuer or (b) an
entity specifically identified in such written statement as directly or indirectly controlling or
controlled by or under direct or indirect common control with the Issuer.

     Section 12.05 Mandatory and Optional Sinking Funds. The minimum amount of any sinking fund payment
provided for by the terms of the Securities of any series is herein referred to as a “mandatory
sinking fund payment”, and any payment in excess of such minimum amount provided for by the terms
of the Securities of any series is herein referred to as an “optional sinking fund payment”. The
date on which a sinking fund payment is to be made is herein referred to as the “sinking fund
payment date”.

     In lieu of making all or any part of any mandatory sinking fund payment with respect to any
series of Securities in cash, the Issuer may at its option (a) deliver to the Trustee Securities of
such series theretofore purchased or otherwise acquired (except upon redemption pursuant to the
mandatory sinking fund) by the Issuer or receive credit for Securities of such series (not
previously so credited) theretofore purchased or otherwise acquired (except as aforesaid) by the
Issuer and delivered to the Trustee for cancellation pursuant to Section 2.10 and, if applicable,
receive credit for Securities (not previously so credited) converted into Common Stock and so
delivered to the Trustee for cancellation, (b) receive credit for optional sinking fund payments
(not previously so credited) made pursuant to this Section, or (c) receive credit for Securities of
such series (not previously so credited) redeemed by the Issuer through any optional redemption
provision contained in the terms of such series. Securities so delivered or credited shall be
received or credited by the Trustee at the sinking fund redemption price specified in such
Securities.

     On or before the 60th day next preceding each sinking fund payment date for any series, the
Issuer will deliver to the Trustee an Officer’s Certificate (which need not contain the statements
required by Section 11.05) (a) specifying the portion of the mandatory sinking fund payment to be
satisfied by payment of cash and the portion to be satisfied by credit of Securities of such series
and the basis for such credit, (b) stating that none of the Securities of such series for which
credit will be taken has theretofore been so credited, (c) stating that no defaults in the payment
of interest or Events of Default with respect to such series have occurred (which have not been
waived or cured) and are continuing and (d) stating whether or not the Issuer intends to exercise
its right to make an optional sinking fund payment with respect to such series and, if so,
specifying the amount of such optional sinking fund payment which the Issuer intends to pay on

-48-

 

or before the next succeeding sinking fund payment date. Any Securities of such series to be
credited and required to be delivered to the Trustee in order for the Issuer to be entitled to
credit therefor as aforesaid which have not theretofore been delivered to the Trustee shall be
delivered for cancellation pursuant to Section 2.10 to the Trustee with such Officer’s Certificate
(or reasonably promptly thereafter if acceptable to the Trustee). Such Officer’s Certificate shall
be irrevocable and upon its receipt by the Trustee the Issuer shall become unconditionally
obligated to make all the cash payments or payments therein referred to, if any, on or before the
next succeeding sinking fund payment date. Failure of the Issuer, on or before any such 60th day,
to deliver such Officer’s Certificate and Securities specified in this paragraph, if any, shall not
constitute a default but shall constitute, on and as of such date, the irrevocable election of the
Issuer that the mandatory sinking fund payment for such series due on the next succeeding sinking
fund payment date shall be paid entirely in cash without the option to deliver or credit Securities
of such series in respect thereof.

     If the sinking fund payment or payments (mandatory or optional or both) to be made in cash on
the next succeeding sinking fund payment date plus any unused balance of any preceding sinking fund
payments made in cash shall exceed $50,000 (or the equivalent thereof in any Foreign Currency or a
lesser sum in Dollars or in any Foreign Currency if the Issuer shall so request) with respect to
the Securities of any particular series, such cash shall be applied on the next succeeding sinking
fund payment date to the redemption of Securities of such series at the sinking fund redemption
price together with accrued interest to the date fixed for redemption. If such amount shall be
$50,000 (or the equivalent thereof in any Foreign Currency) or less and the Issuer makes no such
request then it shall be carried over until a sum in excess of $50,000 (or the equivalent thereof
in any Foreign Currency) is available, which delay in accordance with this paragraph shall not be a
default or a breach of the obligation to make such payment. The Trustee shall select, in the
manner provided in Section 12.02, for redemption on such sinking fund payment date a sufficient
principal amount of Securities of such series to absorb said cash, as nearly as may be, and shall
(if requested in writing by the Issuer) inform the Issuer of the serial numbers of the Securities
of such series (or portions thereof) so selected. The Trustee, in the name and at the expense of
the Issuer (or the Issuer, if it shall so request the Trustee in writing), shall cause notice of
redemption of the Securities of such series to be given in substantially the manner provided in
Section 12.02 (and with the effect provided in Section 12.03) for the redemption of Securities of
such series in part at the option of the Issuer. The amount of any sinking fund payments not so
applied or allocated to the redemption of Securities of such series shall be added to the next cash
sinking fund payment for such series and, together with such payment, shall be applied in
accordance with the provisions of this Section. Any and all sinking fund moneys held on the stated
maturity date of the Securities of any particular series (or earlier, if such maturity is
accelerated), which are not held for the payment or redemption of particular Securities of such
series, shall be applied, together with other moneys, if necessary, sufficient for the purpose, to
the payment of the principal of, and interest on, the Securities of such series at maturity. The
Issuer’s obligation to make a mandatory or optional sinking fund payment shall automatically be
reduced by an amount equal to the sinking fund redemption price allocable to any Securities or
portions thereof called for redemption pursuant to the preceding paragraph on any sinking fund
payment date and converted into Common Stock; provided that, if the Trustee is not the conversion
agent for the Securities, the Issuer or such conversion agent shall give the Trustee written notice
prior to the date fixed for redemption of the principal amount of Securities or portions thereof so
converted.

-49-

 

     On or before each sinking fund payment date, the Issuer shall pay to the Trustee in cash or
shall otherwise provide for the payment of all interest accrued to the date fixed for redemption on
Securities to be redeemed on the next following sinking fund payment date.

     The Trustee shall not redeem or cause to be redeemed any Securities of a series with sinking
fund moneys or give any notice of redemption of Securities for such series by operation of the
sinking fund during the continuance of a default in payment of interest on such Securities or of
any Event of Default except that, where the mailing of notice of redemption of any Securities shall
theretofore have been made, the Trustee shall redeem or cause to be redeemed such Securities,
provided that it shall have received from the Issuer a sum sufficient for such redemption. Except
as aforesaid, any moneys in the sinking fund for such series at the time when any such default or
Event of Default shall occur, and any moneys thereafter paid into the sinking fund, shall, during
the continuance of such default or Event of Default, be deemed to have been collected under Article
5 and held for the payment of all such Securities. In case such Event of Default shall have been
waived as provided in Section 5.10, or the default cured on or before the 60th day preceding the
sinking fund payment date in any year, such moneys shall thereafter be applied on the next
succeeding sinking fund payment date in accordance with this Section to the redemption of such
Securities.

ARTICLE 13

SUBORDINATION OF SECURITIES

     Section 13.01 Agreement of Subordination. The Issuer covenants and agrees, and each holder of
Securities issued hereunder by its acceptance thereof likewise covenants and agrees, that all
Securities shall be issued subject to the provisions of this Article 13; and each Securityholder,
whether upon original issue or upon transfer or assignment thereof, accepts and agrees to be bound
by such provisions.

     The payment of the principal of, premium, if any, and interest on all Securities issued
hereunder shall, to the extent and in the manner hereinafter set forth, be subordinated and subject
in right of payment to the prior payment in full of all Senior Indebtedness of the Issuer, whether
outstanding at the date of this Indenture or thereafter incurred.

     The provisions of this Article 13 define the subordination of the Securities, as obligations
of the Issuer, with respect to Senior Indebtedness of the Issuer.

     No provision of this Article 13 shall prevent the occurrence of any default or Event of
Default hereunder.

     Section 13.02 Payments to Securityholders. In the event and during the continuation of any default
in the payment of principal, premium, interest or any other payment due on any Senior Indebtedness
of the Issuer continuing beyond the period of grace, if any, specified in the instrument or lease
evidencing such Senior Indebtedness of the Issuer, then, unless and until such default shall have
been cured or waived or shall have ceased to exist, no payment shall be made by the Issuer with
respect to the principal of, or premium, if any, or interest on the Securities, except sinking fund
obligations satisfied by credit of acquired Securities under Section 12.05

-50-

 

prior to the happening of such default and payments made pursuant to Article 10 hereof from monies
deposited with the Trustee pursuant thereto prior to the happening of such default.

     Upon any payment by the Issuer, or distribution of assets of the Issuer of any kind or
character, whether in cash, property or securities, to creditors upon any dissolution or winding-up
or liquidation or reorganization of the Issuer, whether voluntary or involuntary or in bankruptcy,
insolvency, receivership or other proceedings, all amounts due or to become due upon all Senior
Indebtedness of the Issuer shall first be paid in full, or payment thereof provided for in money in
accordance with its terms, before any payment is made on account of the principal (and premium, if
any) or interest on the Securities (except payments made pursuant to Article 10 hereof from monies
deposited with the Trustee pursuant thereto prior to the happening of such dissolution, winding-up,
liquidation or reorganization); and upon any such dissolution or winding-up or liquidation or
reorganization any payment by the Issuer, or distribution of assets of the Issuer of any kind or
character, whether in cash, property or securities, to which the holders of the Securities or the
Trustee would be entitled, except for the provisions of this Article 13, shall (except as
aforesaid) be paid by the Issuer or by any receiver, trustee in bankruptcy, liquidating trustee,
agent or other Person making such payment or distribution, or by the holders of the Securities or
by the Trustee under this Indenture if received by them or it, directly to the holders of Senior
Indebtedness of the Issuer (pro rata to such holders on the basis of the respective amounts of
Senior Indebtedness of the Issuer held by such holders, as calculated by the Issuer) or their
representative or representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Senior Indebtedness of the Issuer may have been issued, as
their respective interests may appear, to the extent necessary to pay all Senior Indebtedness of
the Issuer in full, in money or money’s worth, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness of the Issuer, before any payment or
distribution is made to the holders of the Securities or to the Trustee.

     In the event that, notwithstanding the foregoing, any payment or distribution of assets of the
Issuer of any kind or character, whether in cash, property or securities, prohibited by the
foregoing, shall be received by the Trustee or the holders of the Securities before all Senior
Indebtedness of the Issuer is paid in full, or provision is made for such payment in money in
accordance with its terms, such payment or distribution shall be held in trust for the benefit of
and shall be paid over or delivered to the holders of Senior Indebtedness of the Issuer or their
representative or representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Senior Indebtedness of the Issuer may have been issued, as
their respective interests may appear, as calculated by the Issuer, for application to the payment
of all Senior Indebtedness of the Issuer remaining unpaid to the extent necessary to pay all Senior
Indebtedness of the Issuer in full in money in accordance with its terms, after giving effect to
any concurrent payment or distribution to or for the holders of such Senior Indebtedness.

     For purposes of this Article 13, the words, “cash, property or securities” shall not be deemed
to include shares of stock of the Issuer as reorganized or readjusted, or securities of the Issuer
or any other corporation provided for by a plan of reorganization or readjustment, the payment of
which is subordinated at least to the extent provided in this Article 13 with respect to the
Securities to the payment of all Senior Indebtedness of the Issuer which may at the time be
outstanding; provided that (i) the Senior Indebtedness of the Issuer is assumed by the new

-51-

 

corporation, if any, resulting from any such reorganization or readjustment, and (ii) the
rights of the holders of the Senior Indebtedness of the Issuer (other than leases) and of leases
which are assumed are not, without the consent of such holders, altered by such reorganization or
readjustment. The consolidation of the Issuer with, or the merger of the Issuer into, another
corporation or the liquidation or dissolution of the Issuer following the conveyance or transfer of
its property as an entirety, or substantially as an entirety, to another corporation upon the terms
and conditions provided for in Article 9 hereof shall not be deemed a dissolution, winding-up,
liquidation or reorganization for the purposes of this Section 13.02 if such other corporation
shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions
stated in Article 9 hereof. Nothing in this Section 13.02 shall apply to claims of, or payments
to, the Trustee under or pursuant to Section 6.06.

     Section 13.03 Subrogation of Securities. Subject to the payment in full of all Senior Indebtedness
of the Issuer, the rights of the holders of the Securities shall be subrogated to the rights of the
holders of Senior Indebtedness of the Issuer to receive payments or distributions of cash, property
or securities of the Issuer applicable to the Senior Indebtedness of the Issuer until the principal
of (and premium, if any) and interest on the Securities shall be paid in full; and, for the
purposes of such subrogation, no payments or distributions to the holders of the Senior
Indebtedness of the Issuer of any cash, property or securities to which the holders of the
Securities or the Trustee would be entitled except for the provisions of this Article 13 to or for
the benefit of the holders of Senior Indebtedness of the Issuer by holders of the Securities or the
Trustee, shall, as between the Issuer, its creditors other than holders of Senior Indebtedness of
the Issuer, and the holders of the Securities, be deemed to be a payment by the Issuer to or on
account of the Senior Indebtedness of the Issuer. It is understood that the provisions of this
Article 13 are and are intended solely for the purpose of defining the relative rights of the
holders of the Securities, on the one hand, and the holders of the Senior Indebtedness of the
Issuer, on the other hand.

     Nothing contained in this Article 13 or elsewhere in this Indenture or in the Securities is
intended to or shall impair, as between the Issuer, its creditors other than the holders of its
Senior Indebtedness, and the holders of the Securities, the obligation of the Issuer, which is
absolute and unconditional, to pay to the holders of the Securities the principal of (and premium,
if any) and interest on the Securities as and when the same shall become due and payable in
accordance with their terms, or is intended to or shall affect the relative rights of the holders
of the Securities and creditors of the Issuer other than the holders of its Senior Indebtedness,
nor shall anything herein or therein prevent the Trustee or the holder of any Security from
exercising all remedies otherwise permitted by applicable law upon default under this Indenture,
subject to the rights, if any, under this Article 13 of the holders of Senior Indebtedness of the
Issuer in respect of cash, property or securities of the Issuer received upon the exercise of any
such remedy.

     Upon any payment or distribution of assets of the Issuer referred to in this Article 13, the
Trustee, subject to the provisions of Section 6.01, and the holders of the Securities shall be
entitled to rely upon any order or decree made by any court of competent jurisdiction in which such
dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate of
the receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment
or distribution, delivered to the Trustee or to the holders of the Securities, for the purpose of
ascertaining the Persons entitled to participate in such distribution, the holders of the

-52-

 

Senior Indebtedness and other indebtedness of the Issuer, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article 13.

     Section 13.04 Authorization by Securityholders. Each holder of a Security by its acceptance
thereof authorizes and directs the Trustee on its behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article 13 appoints the Trustee its
attorney-in-fact for any and all such purposes.

     Section 13.05 Notice to Trustee. The Issuer shall give promptly written notice to a Responsible
Officer of the Trustee of any fact known to the Issuer which would prohibit the making of any
payment of monies to or by the Trustee in respect of the Securities pursuant to the provisions of
this Article 13. Notwithstanding the provisions of this Article 13 or any other provision of this
Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which
would prohibit the making of any payment of monies to or by the Trustee in respect of the
Securities pursuant to the provisions of this Article 13, unless and until a Responsible Officer of
the Trustee shall have received written notice thereof at the Corporate Trust Office of the Trustee
from the Issuer or a holder or holders of Senior Indebtedness of the Issuer or from any trustee
therefor; and before the receipt of any such written notice, the Trustee, subject to the provisions
of Section 6.01, shall be entitled in all respects to assume that no such facts exist; provided
that if on a date not fewer than three Business Days prior to the date upon which by the terms
hereof any such monies may become payable for any purpose (including, without limitation, the
payment of the principal of (or premium, if any) or interest on any Security) the Trustee shall not
have received, with respect to such monies, the notice provided for in this Section 13.05, then,
anything herein contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such monies and to apply the same to the purpose for which they were received,
and shall not be affected by any notice to the contrary which may be received by it on or after
such prior date. Notwithstanding anything to the contrary hereinbefore set forth, nothing shall
prevent any payment by the Issuer or the Trustee to the Securityholders of monies in connection
with a redemption of Securities if (i) notice of such redemption has been given pursuant to Article
12 or Section 10.01 hereof prior to the receipt by the Trustee of written notice as aforesaid, and
(ii) such notice of redemption is given not earlier than 60 days before the redemption date.

     The Trustee conclusively shall be entitled to rely on the delivery to it of a written notice
by a Person representing himself to be a holder of Senior Indebtedness of the Issuer (or a trustee
on behalf of such holder) to establish that such notice has been given by a holder of Senior
Indebtedness of the Issuer or a trustee on behalf of any such holder or holders. In the event that
the Trustee determines in good faith that further evidence is required with respect to the right of
any Person as a holder of Senior Indebtedness of the Issuer to participate in any payment or
distribution pursuant to this Article 13, the Trustee may request such Person to furnish evidence
to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness of the Issuer
held by such Person, the extent to which such Person is entitled to participate in such payment or
distribution and any other facts pertinent to the rights of such Person under this Article 13, and
if such evidence is not furnished the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

-53-

 

     Section 13.06 Trustee’s Relation to Senior Indebtedness. The Trustee in its individual capacity
shall be entitled to all the rights set forth in this Article 13 in respect of any Senior
Indebtedness of the Issuer at any time held by it, to the same extent as any other holder of Senior
Indebtedness of the Issuer and nothing elsewhere in this Indenture shall deprive the Trustee of any
of its rights as such holder.

     With respect to the holders of Senior Indebtedness of the Issuer, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are specifically set forth in
this Article 13, and no implied covenants or obligations with respect to the holders of Senior
Indebtedness of the Issuer shall be read into this Indenture against the Trustee. The Trustee
shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness of the Issuer
and the Trustee shall not be liable to any holder of Senior Indebtedness of the Issuer if it shall
pay over or deliver to holders of Securities, the Issuer or any other Person money or assets to
which any holder of Senior Indebtedness of the Issuer shall be entitled by virtue of this Article
13 or otherwise.

     Section 13.07 No Impairment of Subordination. No right of any present or future holder of any
Senior Indebtedness of the Issuer to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of the Issuer or by any
act or failure to act, in good faith, by any such holder, or by any noncompliance by the Issuer
with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof
which any such holder may have or otherwise be charged with.

     Section 13.08 Rights of Trustee. Nothing in this Article 13 shall apply to claims of or payments
to, the Trustee pursuant to Section 6.06.

(REVERSE OF SECURITY)

BROOKS AUTOMATION, INC.

[ Title of Security ]

	1.	 	Indenture

     This Security is one of a duly authorized issue of debentures, notes or other evidence of
indebtedness (hereinafter called the “Securities”) of the Issuer of the series hereinafter
specified, which series is initially limited in aggregate principal amount to [$]                          , all
of such Securities issued and to be issued under an Indenture dated as of                        ,                 (the
“Indenture”) between the Issuer and                                                              as trustee (the “Trustee”).
Capitalized terms herein are used as defined in the Indenture unless otherwise indicated. 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, as in effect on the date of the Indenture. The
Securities are subject to all such terms, and Holders are referred to the Indenture and the Trust
Indenture Act for a statement of all such terms. To the extent permitted by applicable law, in the
event of any inconsistency between the terms of this Security and the terms of the Indenture, the
terms of the Indenture shall control.

     This Security is one of a series of Securities designated pursuant to the Indenture [and an
[Supplemental Indenture] dated _______, _______, issued pursuant to Section 2.01 and Section 2.03
thereof (the “Supplement”)] as                                         . The Securities are general unsecured obligations
of the Issuer. The Issuer may, subject to the provisions of the Indenture and applicable law,
issue additional Securities of any series under the Indenture.

	2.	 	Method of Payment.

     The Issuer shall pay interest on the Securities (except defaulted interest) to the persons who
are the registered Holders at the close of business on the Interest Record Date immediately
preceding the Interest Payment Date notwithstanding any transfer or exchange of such Security
subsequent to such Interest Record Date and prior to such Interest Payment Date. Holders must
surrender Securities to the Trustee to collect principal payments. The Issuer shall 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 payments of interest, and any portion of the
Principal (other than interest payable at maturity or on any redemption or repayment date or the
final payment of Principal) shall be made by the Paying Agent, upon receipt from the Issuer of
immediately available funds by                          [a./p.m.], New York City time (or such other time as may
be agreed to between the Issuer and the Paying Agent or the Issuer), directly to a Holder (by
Federal funds wire transfer or otherwise) if the Holder has delivered written instructions to the
Trustee 15 days prior to such payment date requesting that such payment will be so made and
designating the bank account to which such payments shall be so made and in the case of payments of
Principal surrenders the same to the Trustee in exchange for a Security or Securities aggregating
the same principal amount as the unredeemed principal amount of the Securities surrendered.]

	3.	 	Redemption.

 

 

     [The Securities of this series may be redeemed at any time [on or after _____, _______], as a
whole or in part, at the option of the Issuer, upon mailing notice of such redemption not less than
30 and not more than 60 days to the Holders of such Securities, at a redemption price equal to
                         .]

	4.	 	Paying Agent and Security Registrar

     Initially, the Trustee will act as Paying Agent and Security Registrar. The Issuer may change
any Paying Agent or Security Registrar without notice to the Holders.

	5.	 	Denominations; Transfer; Exchange.

     The Securities are in registered form, without coupons, in denominations of [$1,000] and
multiples of [$1,000]. A Holder shall register the transfer of or exchange Securities in accordance
with the Indenture. The Issuer may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay certain transfer taxes or similar governmental
charges payable in connection therewith as permitted by the Indenture. [The Issuer need not
register the transfer of or exchange (a) any Securities for a period of fifteen (15) days preceding
the first mailing of notice that such Securities are to be redeemed, or (b) any Securities
selected, called or being called for redemption in whole or in part, except, in the case of any
Security to be redeemed in part, the portion thereof not to be so redeemed.]

	6.	 	Persons Deemed Owners.

     The registered Holder of a Security shall be treated as the owner of it for all purposes.

	7.	 	Unclaimed Funds.

     If funds for the payment of principal or interest remain unclaimed for two years, the Trustee
and the Paying Agent will repay the funds to the Issuer. After that, all liability of the Trustee
and such Paying Agent with respect to such funds shall cease.

	8.	 	Defeasance.

     The Indenture [as amended by the Supplement] contains provisions for defeasance at any time of
(a) the entire indebtedness of the Issuer on this Security and (b) certain restrictive covenants
and the related Events of Default, upon compliance by the Issuer with certain conditions set forth
therein, which provisions [apply] to this Security.

	9.	 	Amendment; Supplement; Waiver.

     Subject to certain exceptions, the Securities and the provisions of the Indenture relating to
the Securities may be amended or supplemented with the written consent of the Holders of at least a
majority in aggregate principal amount of the Securities then outstanding of all series affected by
such amendment or supplement (voting as one class), and any existing Default or Event of Default,
other than the non-payment of the principal amount of or interest on the Securities, or compliance
with certain provisions may be waived with the consent of the Holders of a majority in aggregate
principal amount of all the Securities of such series, each series voting

2

 

as a separate class, (or all of the Securities, as the case may be, voting as a single class)
then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or
supplement the Indenture and the Securities to, among other things, cure any ambiguity, defect or
inconsistency, provide for uncertificated Securities in addition to or in place of certificated
Securities, or make any other change that does not adversely affect the rights of any Holder of a
Security.

	10.	 	Defaults and Remedies.

     If an Event of Default (other than certain bankruptcy Events of Default with respect to the
Issuer) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of Securities of this series then outstanding (voting as a separate class) by notice in
writing to the Issuer (and also to the Trustee if such notice is given by the Holders) may declare
[the entire principal] of the Securities of this series and the interest accrued thereon, if any,
to be due and payable immediately in the manner and with the effect provided in the Indenture. If a
bankruptcy Event of Default with respect to the Issuer occurs and is continuing, then [the entire
principal] of the Securities then outstanding and interest accrued thereon, if any, shall become
due and payable immediately in the manner and with the effect provided in the Indenture. Holders
of Securities may not enforce the Indenture or the Securities except as provided in the Indenture.
The Trustee is not obligated to enforce the Indenture or the Securities unless it has received
indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein
provided, Holders of a majority in aggregate principal amount of the Securities then outstanding to
direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of
Securities notice of certain continuing Defaults or Events of Default if it determines that
withholding notice is in their interest.

	11.	 	Subordination.

     Reference is made to the Indenture, including, without limitation, provisions subordinating
the payment of principal of and premium, if any, and interest on the Securities to the prior
payment in full of all Senior Indebtedness as defined in the Indenture. Such further provisions
shall for all purposes have the same effect as though fully set forth at this place.

	12.	 	Trustee Dealings with Issuer.

     The Trustee under the Indenture, in its individual or any other capacity, may become the owner
or pledgee of Securities and may otherwise deal with the Issuer as if it were not the Trustee.

	13.	 	No Recourse Against Others.

     No stockholder, director, officer, employee or incorporator, past, present or future as such,
of the Issuer or any predecessor or successor corporation thereof shall have any liability for any
obligation 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 Holder of a Security by accepting a Security
waives and releases all such liability. The waiver and release are part of the consideration for
the issuance of the Securities.

	14.	 	Authentication.

     This Security shall not be valid until the Trustee manually signs the certificate of
authentication on this Security.

	15.	 	Abbreviations and Defined Terms.

     Customary abbreviations may be used in the name of a Holder of a Security or an assignee, such
as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants
with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (=
Uniform Gifts to Minors Act).

	16.	 	CUSIP Numbers.

     Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification
Procedures, the Issuer has caused CUSIP numbers to be printed on the Securities as a convenience to
the Holders of the Securities. No representation is made as to the accuracy of such numbers as
printed on the Securities and reliance may be placed only on the other identification numbers
printed hereon.

	17.	 	Governing Law.

     The laws of the State of New York shall govern the Indenture and this Security thereof, and
for all purposes this Security shall be governed by and construed in accordance with the laws of
such State without regard to any principle of conflict of laws that would require or permit the
application of the laws of any other jurisdiction, except as may otherwise be required by mandatory
provisions of law.
