waiver or other action provided in or pursuant to this Indenture to be given or taken by Holders of

such record. Except as herein otherwise expressly provided, such action shall become effective when
such instrument or instruments or record or both are delivered to the Trustee and, where it is
hereby expressly required, to the Company. Such instrument or instruments and any such record (and
the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of
the Holders signing such instrument or instruments or so voting at any such meeting. Proof of
execution of any such instrument or of a writing appointing any such agent, or of the holding by
any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to
Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee and the Company
and any agent of the Trustee or the Company, if made in the manner provided in this Section
1.4. The record of any meeting of Holders of Securities shall be proved in the manner provided
in Section 15.6.

     Without limiting the generality of this Section 1.4, unless otherwise provided in or
pursuant to this Indenture, a Holder, including a U.S. Depository that is a Holder of a global
Security, may make, give or take, by a proxy or proxies duly appointed in writing, any request,

global Security through such U.S. Depository’s standing instructions and customary practices.

     The Company shall fix a record date for the purpose of determining the Persons who are
beneficial owners of interest in any permanent global Security held by a U.S. Depository entitled
under the procedures of such U.S. Depository to make, give or take, by a proxy or proxies duly
appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or
other Act provided in or pursuant to this Indenture to be made, given or taken by Holders. If such
a record date is fixed, the Holders on such record date or their duly appointed proxy or proxies,
and only such Persons, shall be entitled to make, give or take such request, demand, authorization,
direction, notice, consent, waiver or other Act, whether or not such Holders remain Holders after
such record date. No such request, demand, authorization, direction, notice, consent, waiver or
other Act shall be valid or effective if made, given or taken more than 90 days after such record
date.

     (a) The fact and date of the execution by any Person of any such instrument or writing
referred to in this Section 1.4 may be proved in any reasonable manner; and the
Trustee may in any instance require further proof with respect to any of the matters
referred to in this Section 1.4.

     (b) The ownership, principal amount and serial numbers of Registered Securities held by
any Person, and the date of the commencement and the date of the termination of holding the
same, shall be proved by the Security Register.

11

 

     (c) The ownership, principal amount and serial numbers of Bearer Securities held by any
Person, and the date of the commencement and the date of the termination of holding the
same, may be proved by the production of such Bearer Securities or by a certificate
executed, as depositary, by any trust company, bank, banker or other depositary reasonably
acceptable to the Company, wherever situated, if such certificate shall be deemed by the
Company and the Trustee to be satisfactory, showing that at the date therein mentioned such
Person had on deposit with such depositary, or exhibited to it, the Bearer Securities
therein described; or such facts may be proved by the certificate or affidavit of the Person
holding such Bearer Securities, if such certificate or affidavit is deemed by the Trustee
to be satisfactory. The Trustee and the Company may assume that such ownership of any Bearer
Security continues until (i) another certificate or affidavit bearing a later date issued in
respect of the same Bearer Security is produced, or (ii) such Bearer Security is produced to
the Trustee by some other Person, or (iii) such Bearer Security is surrendered in exchange
for a Registered Security, or (iv) such Bearer Security is no longer Outstanding. The
ownership, principal amount and serial numbers of Bearer Securities held by the Person so
executing such instrument or writing and the date of the commencement and the date of the
termination of holding the same may also be proved in any other manner which the Company and
the Trustee deem sufficient.

     (d) If the Company shall solicit from the Holders of any Registered Securities any
request, demand, authorization, direction, notice, consent, waiver or other Act, the Company
may at its option (but is not obligated to), by Board Resolution, fix in advance a record
date for the determination of Holders of Registered Securities entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other Act. If such a
record date is fixed, such request, demand, authorization, direction, notice, consent,
waiver or other Act may be given before or after such record date, but only the Holders of
Registered Securities of record at the close of business on such record date shall be deemed
to be Holders for the purpose of determining whether Holders of the requisite proportion of
Outstanding Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that purpose the
Outstanding Securities shall be computed as of such record date; provided that no such
authorization, agreement or consent by the Holders of Registered Securities shall be deemed
effective unless it shall become effective pursuant to the provisions of this Indenture not
later than six months after the record date.

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

     Section 1.5. Notices, etc. to Trustee and Company.

     Any request, demand, authorization, direction, notice, consent, waiver or other Act of Holders
or other document provided or permitted by this Indenture to be made upon, given or furnished to,
or filed with,

12

 

     (a) the Trustee by any Holder or the Company shall be sufficient for every purpose
hereunder if made, given, furnished or filed in writing to or with the Trustee at its
Corporate Trust Office, or

     (b) the Company by the Trustee or any Holder shall be sufficient for every purpose
hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class
postage prepaid, to the Company addressed to the attention of its Treasurer with a copy to
the attention of its General Counsel, at the address of its principal office specified in
the first paragraph of this instrument or at any other address previously furnished in
writing to the Trustee by the Company.

     Section 1.6. Notice to Holders of Securities; Waiver.

     Except as otherwise expressly provided in or pursuant to this Indenture, where this Indenture
provides for notice to Holders of Securities of any event,

     (a) such notice shall be sufficiently given to Holders of Registered Securities if in
writing and mailed, first-class postage prepaid, to each Holder of a Registered Security
affected by such event, at his address as it appears in the Security Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the giving of
such notice; and

     (b) such notice shall be sufficiently given to Holders of Bearer Securities, if any, if
published in an Authorized Newspaper in The City of New York and, if such Securities are
then listed on any stock exchange outside the United States, in an Authorized Newspaper in
such city as the Company shall advise the Trustee that such stock exchange so requires, on a
Business Day at least twice, the first such publication to be not earlier than the earliest
date and the second such publication not later than the latest date prescribed for the
giving of such notice.

     In any case where notice to Holders of Registered Securities is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a
Registered Security shall affect the sufficiency of such notice with respect to other Holders of
Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as
provided herein. Any notice which is mailed in the manner herein provided shall be conclusively
presumed to have been duly given or provided. In the case by reason of the suspension of regular
mail service or by reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall constitute a
sufficient notification for every purpose hereunder.

     In case by reason of the suspension of publication of any Authorized Newspaper or Authorized
Newspapers or by reason of any other cause it shall be impracticable to publish any notice to
Holders of Bearers Securities as provided above, then such notification to Holders of Bearer
Securities as shall be given with the approval of the Trustee shall constitute sufficient notice to
such Holders for every purpose hereunder. Neither failure to give notice by publication to Holders
of Bearer Securities as provided above, nor any defect in any notice so published,

13

 

shall affect the sufficiency of any notice mailed to Holders of Registered Securities as
provided above.

     Where this Indenture provides for notice in any manner, such notice may be waived in writing
by the Person entitled to receive such notice, either before or after the event, and such waiver
shall be the equivalent of such notice. Waivers of notice by Holders of Securities 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 1.7. Language of Notices.

     Any request, demand, authorization, direction, notice, consent, election or waiver required or
permitted under this Indenture shall be in the English language, except that, if the Company so
elects, any published notice may be in an official language of the country of publication.

     Section 1.8. Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with any duties under any required
provision of the Trust Indenture Act imposed hereon by Section 318(c) thereof, such
required provision shall control.

     Section 1.9. Effect of Headings and Table of Contents.

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

     Section 1.10. Successors and Assigns.

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

or unenforceable, the validity, legality and enforceability of the remaining provisions shall not
in any way be affected or impaired thereby.

     Section 1.12. Benefits of Indenture.

     Nothing in this Indenture, any Security or any Coupon, express or implied, shall give to any
Person, other than the parties hereto, any Security Registrar, any Paying Agent, any Authenticating

legal or equitable right, remedy or claim under this Indenture.

14

entered into and, in each case, performed in said state.

     Unless otherwise specified in or pursuant to this Indenture or any Securities, in any case
where any Interest Payment Date, Stated Maturity or Maturity of any Security, or the last date on
which a Holder has the right to convert or exchange Securities of a series that are convertible or
exchangeable, shall be a Legal Holiday at any Place of Payment, then (notwithstanding any other
provision of this Indenture, any Security or any Coupon other than a provision in any Security or
Coupon that specifically states that such provision shall apply in lieu hereof) payment need not be
made at such Place of Payment on such date, and such Securities need not be converted or exchanged
on such date but such payment may be made, and such Securities may be converted or exchanged, on
the next succeeding day that is a Business Day at such Place of Payment with the same force and
effect as if made on the Interest Payment Date or at the Stated Maturity or Maturity or on such
last day for conversion or exchange, and no interest shall accrue on the amount payable on such

Maturity or last day for conversion or exchange, as the case may be, to such next succeeding
Business Day.

Securities of any series (the “Required Currency”) into a currency in which a judgment will be
rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in The City of New York the
requisite amount of the Required Currency with the Judgment Currency on the New York Banking Day
preceding the day on which a final unappealable judgment is given and (b) its obligations under
this Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied
by any tender, or any recovery pursuant to any judgment (whether or not entered in accordance with
clause (a)), in any currency other than the Required Currency, except to the extent that such
tender or recovery shall result in the actual receipt, by the payee, of the full amount of the
Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as
an alternative or additional cause of action for the purpose of recovering in the Required Currency
the amount, if any, by which such actual receipt shall fall short of the full amount of the
Required Currency so expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture. For purposes of the

such series shall be substantially identical except as to Currency of payments due thereunder,
denomination and the rate of interest thereon, or method of determining the rate of interest, if

that such persons are authorized to determine, consistent with such Officer’s Certificate or any

are specified in such Officer’s Certificate or supplemental indenture. All Securities of any one
series need not be issued at the same time and, unless otherwise so provided, a series may be
reopened for issuances of additional Securities of such series or to establish additional terms of
such series of Securities.

     If any of the terms of the Securities of any series shall be established by action taken by or

22

 

     Section 3.3. Execution, Authentication, Delivery and Dating.

     Securities shall be executed on behalf of the Company by its Chairman of the Board, a Vice
Chairman, its President, Chief Financial Officer, Chief Investment Officer or Chief Accounting
Officer under its corporate seal reproduced thereon and attested by its Secretary or an Assistant
Secretary. Coupons shall be executed on behalf of the Company by the Chief Financial Officer or
Chief Accounting Officer of the Company. The signature of any of these officers on the Securities
or any Coupons appertaining thereto may be manual or facsimile.

     Securities and any Coupons appertaining thereto bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of such Securities and Coupons or did not hold such offices at the date
of original issuance of such Securities or Coupons.

     At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities, together with any Coupons appertaining thereto, executed by the
Company, to the Trustee for authentication and, provided that the Board Resolution and Officer’s
Certificate or supplemental indenture or indentures with respect to such Securities referred to in
Section 3.1 and a Company Order for the authentication and delivery of such Securities have
been delivered to the Trustee, the Trustee in accordance with the Company Order and subject to the
provisions hereof and of such Securities shall authenticate and deliver such Securities. In
authenticating such Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities and any Coupons appertaining thereto, the Trustee shall be entitled
to receive, and (subject to Sections 315(a) through 315(d) of the Trust Indenture
Act) shall be fully protected in relying upon,

     Section 3.4. an Opinion of Counsel to the effect that:

     (1) the form or forms and terms of such Securities and Coupons, if any, have been established
in conformity with the provisions of this Indenture;

     (2) all conditions precedent to the authentication and delivery of such Securities and
Coupons, if any, appertaining thereto, have been complied with and that appropriate insertions,
executed under the Company’s corporate seal and attested by duly authorized officers of the
Company, delivered by duly authorized officers of the Company to the Trustee for authentication
pursuant to this Indenture, and authenticated and delivered by the Trustee and issued by the
Company in the manner and subject to any conditions specified in such Opinion of Counsel, will
constitute legally valid and binding obligations of the Company, enforceable against the Company in
accordance with their terms, except as enforcement thereof may be subject to or limited by
bankruptcy, insolvency, reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent
transfer or other similar laws relating to or affecting creditors’ rights generally, and subject to
general principles of equity (regardless of whether enforcement is sought in a proceeding in equity
or at law) and will entitle the Holders thereof to the benefits of this Indenture; such Opinion of
Counsel need express no opinion as to the availability of equitable remedies;

23

 

     (3) all laws and requirements in respect of the execution and delivery by the Company of such
Securities and Coupons, if any, have been complied with; and

     (4) this Indenture has been qualified under the Trust Indenture Act; and

     (a) an Officer’s Certificate stating that all conditions precedent to the execution,
authentication and delivery of such Securities and Coupons, if any, appertaining thereto,
have been complied with and that, to the best knowledge of the Persons executing such
certificate, no event which is, or after notice or lapse of time would become, an Event of
Default with respect to any of the Securities shall have occurred and be continuing.

     If all the Securities of any series are not to be issued at one time, it shall not be
necessary to deliver an Opinion of Counsel and an Officer’s Certificate at the time of issuance of
each Security, but such opinion and certificate, with appropriate modifications, shall be delivered
at or before the time of issuance of the first Security of such series. After any such first
delivery, any separate written request by an Authorized Officer of the Company or any person
designated in writing by an Authorized Officer that the Trustee authenticate and deliver Securities
of such series for original issue will be deemed to be a certification by the Company that all
conditions precedent provided for in this Indenture relating to authentication and delivery of such
Securities continue to have been complied with and that no Event of Default with respect to any of
the Securities has occurred or is continuing.

     The Trustee shall not be required to authenticate or to cause an Authenticating Agent to
authenticate any Securities if the issue of such Securities pursuant to this Indenture will affect
the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise
in a manner which is not reasonably acceptable to the Trustee or if the Trustee, being advised by
counsel, determines that such action may not lawfully be taken.

     Each Registered Security shall be dated the date of its authentication. Each Bearer Security
and any Bearer Security in global form shall be dated as of the date specified in or pursuant to
this Indenture.

     No Security or Coupon appertaining thereto shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose, unless there appears on such Security a
certificate of authentication substantially in the form provided for in Section 2.2 or
6.11 executed by or on behalf of the Trustee or by the Authenticating Agent by the manual
signature of one of its authorized officers. Such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated and delivered
hereunder. Except as permitted by Section 3.6 or 3.7, the Trustee shall not
authenticate and deliver any Bearer Security unless all Coupons appertaining thereto then matured
have been detached and cancelled.

     Section 3.5. Temporary Securities.

     Pending the preparation of definitive Securities, the Company may execute and deliver to the
Trustee and, upon Company Order, the Trustee shall authenticate and deliver, in the manner provided
in Section 3.3, temporary Securities in lieu thereof which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially

24

 

of the tenor of the definitive Securities in lieu of which they are issued, in registered form
or, if authorized in or pursuant to this Indenture, in bearer form with one or more Coupons or
without Coupons and with such appropriate insertions, omissions, substitutions and other variations
as the officers of the Company executing such Securities may determine, as conclusively evidenced
by their execution of such Securities. Such temporary Securities may be in global form.

     Except in the case of temporary Securities in global form, which shall be exchanged in
accordance with the provisions thereof, if temporary Securities are issued, the Company shall cause
definitive Securities to be prepared without unreasonable delay. After the preparation of
definitive Securities of the same series and containing terms and provisions that are identical to
those of any temporary Securities, such temporary Securities shall be exchangeable for such
definitive Securities upon surrender of such temporary Securities at an Office or Agency for such
Securities, without charge to any Holder thereof. Upon surrender for cancellation of any one or
more temporary Securities (accompanied by any unmatured Coupons appertaining thereto), the Company
shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same series and containing
identical terms and provisions; provided, however, that no definitive Bearer Security, except as
provided in or pursuant to this Indenture, shall be delivered in exchange for a temporary
Registered Security; and provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions set forth in or
pursuant to this Indenture. Unless otherwise provided in or pursuant to this Indenture with respect
to a temporary global Security, until so exchanged the temporary Securities of any series shall in
all respects be entitled to the same benefits under this Indenture as definitive Securities of such
series.

     Section 3.6. Registration, Transfer and Exchange.

     With respect to the Registered Securities of each series, if any, the Company shall cause to
be kept a register (each such register being herein sometimes referred to as the “Security
Register”) at an Office or Agency for such series in which, subject to such reasonable regulations
as it may prescribe, the Company shall provide for the registration of the Registered Securities of
such series and of transfers of the Registered Securities of such series. Such Office or Agency
shall be the “Security Registrar” for that series of Securities. Unless otherwise specified in or
pursuant to this Indenture or the Securities, the Trustee shall be the initial Security Registrar
for each series of Securities. The Company shall have the right to remove and replace from time to
time the Security Registrar for any series of Securities; provided that no such removal or
replacement shall be effective until a successor Security Registrar with respect to such series of
Securities shall have been appointed by the Company and shall have accepted such appointment by the
Company. In the event that the Trustee shall not be or shall cease to be Security Registrar with
respect to a series of Securities, it shall have the right to examine the Security Register for
such series at all reasonable times. There shall be only one Security Register for each series of
Securities.

     Upon surrender for registration of transfer of any Registered Security of any series at any
Office or Agency for such series, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more new Registered
Securities of the same series denominated as authorized in or pursuant to this Indenture, of a like

25

 

aggregate principal amount bearing a number not contemporaneously outstanding and containing
identical terms and provisions.

     At the option of the Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series containing identical terms and provisions, in any
authorized denominations, and of a like aggregate principal amount, upon surrender of the
Securities to be exchanged at any Office or Agency for such series. Whenever any Registered
Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities which the Holder making the exchange is
entitled to receive.

If provided in or pursuant to this Indenture, with respect to Securities of any series, at the
option of the Holder, Bearer Securities of such series may be exchanged for Registered Securities
of such series containing identical terms, denominated as authorized in or pursuant to this
Indenture and in the same aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any Office or Agency for such series, with all unmatured Coupons and all matured
Coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce
any such unmatured Coupon or Coupons or matured Coupon or Coupons in default, such exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable to the Company and
the Trustee in an amount equal to the face amount of such missing Coupon or Coupons, or the
surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee if there
is furnished to them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Bearer Security shall surrender to any
Paying Agent any such missing Coupon in respect of which such a payment shall have been made, such
Holder shall be entitled to receive the amount of such payment; provided, however, that, except as
otherwise provided in Section 10.2, interest represented by Coupons shall be payable only
upon presentation and surrender of those Coupons at an Office or Agency for such series located
outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such Office or Agency for such series in exchange for a Registered Security
of such series and like tenor after the close of business at such Office or Agency on (i) any
Regular Record Date and before the opening of business at such Office or Agency on the next
succeeding Interest Payment Date, or (ii) any Special Record Date and before the opening of
business at such Office or Agency on the related date for payment of Defaulted Interest, such
Bearer Security shall be surrendered without the Coupon relating to such Interest Payment Date or
proposed date of payment, as the case may be (or, if such Coupon is so surrendered with such Bearer
Security, such Coupon shall be returned to the Person so surrendering the Bearer Security), and
interest or Defaulted Interest, as the case may be, shall not be payable on such Interest Payment
Date or proposed date for payment, as the case may be, in respect of the Registered Security issued
in exchange for such Bearer Security, but shall be payable only to the Holder of such Coupon when
due in accordance with the provisions of this Indenture.

     If provided in or pursuant to this Indenture with respect to Securities of any series, at the
option of the Holder, Registered Securities of such series may be exchanged for Bearer Securities
upon such terms and conditions as may be provided in or pursuant to this Indenture with respect to
such series.

26

 

     Whenever any Securities are surrendered for exchange as contemplated by the immediately
preceding two paragraphs, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to receive.

Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture, any
global Security shall be exchangeable for definitive Securities only if (i) the Depository is at
any time unwilling, unable or ineligible to continue as depository and a successor depository is
not appointed by the Company within 90 days of the date the Company is so informed in writing, (ii)
the Company executes and delivers to the Trustee a Company Order to the effect that such global
Security shall be so exchangeable, or (iii) an Event of Default has occurred and is continuing with
respect to the Securities. If the beneficial owners of interests in a global Security are entitled
to exchange such interests for definitive Securities as the result of an event described in clause
(i), (ii) or (iii) of the preceding sentence, then without unnecessary delay but in any event not
later than the earliest date on which such interests may be so exchanged, the Company shall deliver
to the Trustee definitive Securities in such form and denominations as are required by or pursuant
to this Indenture, and of the same series, containing identical terms and in aggregate principal
amount equal to the principal amount of such global Security, executed by the Company. On or after
the earliest date on which such interests may be so exchanged, such global Security shall be
surrendered from time to time by the U.S. Depository or such other Depository as shall be specified
in the Company Order with respect thereto, and in accordance with instructions given to the Trustee
and the U.S. Depository or such other Depository, as the case may be (which instructions shall be
in writing but need not be contained in or accompanied by an Officer’s Certificate or be
accompanied by an Opinion of Counsel), as shall be specified in the Company Order with respect
thereto to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or in
part, for definitive Securities as described above without charge. The Trustee shall authenticate
and make available for delivery, in exchange for each portion of such surrendered global Security,
a like aggregate principal amount of definitive Securities of the same series of authorized
denominations and of like tenor as the portion of such global Security to be exchanged, which
(unless such Securities are not issuable both as Bearer Securities and as Registered Securities, in
which case the definitive Securities exchanged for the global Security shall be issuable only in
the form in which the Securities are issuable, as provided in or pursuant to this Indenture) shall
be in the form of Bearer Securities or Registered Securities, or any combination thereof, as shall
be specified by the beneficial owner thereof, but subject to the satisfaction of any certification
or other requirements to the issuance of Bearer Securities; provided, however, that no such
exchanges may occur during a period beginning at the opening of business 15 days before any
selection of Securities of the same series to be redeemed and ending on the relevant Redemption
Date; and provided, further, that (unless otherwise provided in or pursuant to this Indenture) no
Bearer Security delivered in exchange for a portion of a global Security shall be mailed or
otherwise delivered to any location in the United States. Promptly following any such exchange in
part, such global Security shall be returned by the Trustee to such Depository or the U.S.
Depository, as the case may be, or such other Depository or U.S. Depository referred to above in
accordance with the instructions of the Company referred to above. If a Registered Security is
issued in exchange for any portion of a global Security after the close of business at the Office
or Agency for such Security where such exchange occurs on or after (i) any Regular Record Date for
such Security and before the opening of business at such Office or Agency on the next
succeeding
Interest Payment Date, or (ii) any Special Record Date

27

 

for such Security and before the opening of business at such Office or Agency on the related
proposed date for payment of interest or Defaulted Interest, as the case may be, interest shall not
be payable on such Interest Payment Date or proposed date for payment, as the case may be, in
respect of such Registered Security, but shall be payable on such Interest Payment Date or proposed
date for payment, as the case may be, only to the Person to whom interest in respect of such
portion of such global Security shall be payable in accordance with the provisions of this
Indenture.

     All Securities issued upon any registration of transfer or exchange of Securities shall be the
valid obligations of the Company evidencing the same debt and entitling the Holders thereof to the
same benefits under this Indenture as the Securities surrendered upon such registration of transfer
or exchange.

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

     No service charge shall be made for any registration of transfer or exchange, or redemption of
Securities, but the Company may require payment of a sum sufficient to cover any tax or other
governmental charge and any other expenses (including fees and expenses of the Trustee) that may be
imposed in connection with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 3.4, 9.5 or 11.7 not involving any transfer.

     Except as otherwise provided in or pursuant to this Indenture, the Company shall not be
required (i) to issue, register the transfer of or exchange any Securities during a period
beginning at the opening of business 15 days before the day of mailing of a notice of redemption of
Securities of like tenor and the same series under Section 11.3 and ending at the close of
business on the day of such mailing, or (ii) to register the transfer of or exchange any Registered
Security selected 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 redeemed, or (iii) to exchange any Bearer Security
selected for redemption except, to the extent provided with respect to such Bearer Security, that
such Bearer Security may be exchanged for a Registered Security of like tenor and the same series,
provided that such Registered Security shall be immediately surrendered for redemption with written
instruction for payment consistent with the provisions of this Indenture or (iv) to issue, register
the transfer of or exchange any Security which, in accordance with its terms, has been surrendered
for repayment at the option of the Holder, except the portion, if any, of such Security not to be
so repaid.

     Section 3.7. Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security or a Security with a mutilated Coupon appertaining to it is
surrendered to the Trustee, subject to the provisions of this Section 3.6, the Company
shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of
the same series containing identical terms and of like principal amount and bearing a number not

28

 

contemporaneously outstanding, with Coupons appertaining thereto corresponding to the Coupons,
if any, appertaining to the surrendered Security.

     If there be delivered to the Company and to the Trustee (i) evidence to their satisfaction of
the destruction, loss or theft of any Security or Coupon, and (ii) such security or indemnity as
may be required by them to save each of them and any agent of either of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security or Coupon has been acquired by a
bona fide purchaser, the Company shall execute and, upon the Company’s request the Trustee shall
authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Security or in exchange for the Security to which a destroyed, lost or stolen Coupon
appertains with all appurtenant Coupons not destroyed, lost or stolen, a new Security of the same
series containing identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding to the Coupons, if
any, appertaining to such destroyed, lost or stolen Security or to the Security to which such
destroyed, lost or stolen Coupon appertains.

     Notwithstanding the foregoing provisions of this Section 3.6, in case any mutilated,
destroyed, lost or stolen Security or Coupon has become or is about to become due and payable, the
Company in its discretion may, instead of issuing a new Security, pay such Security or Coupon;
provided, however, that payment of principal of, any premium or interest on or any Additional
Amounts with respect to any Bearer Securities shall, except as otherwise provided in Section
10.2, be payable only at an Office or Agency for such Securities located outside the United
States and, unless otherwise provided in or pursuant to this Indenture, any interest on Bearer
Securities and any Additional Amounts with respect to such interest shall be payable only upon
presentation and surrender of the Coupons appertaining thereto.

     Upon the issuance of any new Security under this Section 3.6, the Company may require
the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto and any other expenses (including the fees and expenses of the Trustee)
connected therewith.

     Every new Security, with any Coupons appertaining thereto issued pursuant to this Section
3.6 in lieu of any destroyed, lost or stolen Security, or in exchange for a Security to which a
destroyed, lost or stolen Coupon appertains shall constitute a separate obligation of the Company,
whether or not the destroyed, lost or stolen Security and Coupons appertaining thereto or the
destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and shall be entitled
to all the benefits of this Indenture equally and proportionately with any and all other Securities
of such series and any Coupons, if any, duly issued hereunder.

     The provisions of this Section 3.6, as amended or supplemented pursuant to this
Indenture with respect to particular Securities or generally, shall be exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities or Coupons.

     Section 3.8. Payment of Interest and Certain Additional Amounts;

     Rights to Interest and Certain Additional Amounts Preserved.

29

 

     Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional
Amounts with respect to any Registered Security which shall be payable, and are punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such
Security (or one or more Predecessor Securities) is registered as of the close of business on the
Regular Record Date for such interest.

     Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional
Amounts with respect to any Registered Security which shall be payable, but shall not be punctually
paid or duly provided for, on any Interest Payment Date for such Registered Security (herein called
“Defaulted Interest”) shall forthwith cease to be payable to the Holder thereof on the relevant
Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid
by the Company, at its election in each case, as provided in Clause (1) or (2) below:

     The Company may elect to make payment of any Defaulted Interest to the Person in whose name
such Registered Security (or a Predecessor Security thereof) shall be registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed
by the Company in the following manner. The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on such Registered Security, the Special Record
Date therefor and the date of the proposed payment, and at the same time the Company shall deposit
with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of
such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on
or prior to the date of the proposed payment, such money when so deposited to be held in trust for
the benefit of the Person entitled to such Defaulted Interest as in this Clause provided. The
Special Record Date for the payment of such Defaulted Interest shall be not more than 15 days and
not less than 10 days prior to the date of the proposed payment and not less than 10 days after
notification to the Trustee of the proposed payment. The Trustee shall, in the name and at the
expense of the Company, cause notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor to be mailed, first-class postage prepaid, to the Holder of such
Registered Security (or a Predecessor Security thereof) at his address as it appears in the
Security Register not less than 10 days prior to such Special Record Date. The Trustee may, in its
discretion, in the name and at the expense of the Company cause a similar notice to be published at
least once in an Authorized Newspaper of general circulation in the Borough of Manhattan, The City
of New York, but such publication shall not be a condition precedent to the establishment of such
Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the
Person in whose name such Registered Security (or a Predecessor Security thereof) shall be
registered at the close of business on such Special Record Date and shall no longer be payable
pursuant to the following clause (2).

     (2) The Company may make payment of any Defaulted Interest in any other lawful manner
not inconsistent with the requirements of any securities exchange on which such Security may
be listed, and upon such notice as may be required by such exchange, if, after notice given
by the Company to the Trustee of the proposed payment pursuant to this Clause, such payment
shall be deemed practicable by the Trustee. Unless otherwise provided in or pursuant to
this Indenture or the Securities of any particular series pursuant to the provisions of this
Indenture, at the option of the

30

 

Company, interest on Registered Securities that bear interest may be paid by mailing a check
to the address of the Person entitled thereto as such address shall appear in the Security
Register or by transfer to an account maintained by the payee with a bank located in the
United States.

     Subject to the foregoing provisions of this Section 3.8 and Section 3.5, each
Security delivered under this Indenture upon registration of transfer of or in exchange for or in
lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue,
which were carried by such other Security.

     In the case of any Registered Security of any series that is convertible into shares of Common
Stock of the Company or exchangeable for other securities, which Registered Security is converted
or exchanged after any Regular Record Date and on or prior to the next succeeding Interest Payment
Date (other than any Registered Security with respect to which the Stated Maturity is prior to such
Interest Payment Date), interest with respect to which the Stated Maturity is on such Interest
Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion or
exchange, and such interest (whether or not punctually paid or duly provided for) shall be paid to
the Person in whose name that Registered Security (or one or more predecessor Registered
Securities) is registered at the close of business on such Regular Record Date. Except as otherwise
expressly provided in the immediately preceding sentence, in the case of any Registered Security
which is converted or exchanged, interest with respect to which the Stated Maturity is after the
date of conversion or exchange of such Registered Security shall not be payable.

     Section 3.9. Persons Deemed Owners.

     Prior to due presentment of a Registered Security for registration of transfer, the Company,
the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such
Registered Security is registered in the Security Register as the owner of such Registered Security
for the purpose of receiving payment of principal of, any premium and (subject to Sections
3.5 and 3.7) interest on and any Additional Amounts with respect to such Registered
Security and for all other purposes whatsoever, whether or not any payment with respect to such
Registered Security shall be overdue, and none of the Company, the Trustee or any agent of the
Company or the Trustee shall be affected by notice to the contrary.

     The Company, the Trustee and any agent of the Company or the Trustee may treat the bearer of
any Bearer Security or the bearer of any Coupon as the absolute owner of such Security or Coupon
for the purpose of receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not any payment with respect to such Security or Coupon shall be overdue,
and none of the Company, the Trustee or any agent of the Company or the Trustee shall be affected
by notice to the contrary.

     No Holder of any beneficial interest in any global Security held on its behalf by a Depository
shall have any rights under this Indenture with respect to such global Security, and such
Depository may be treated by the Company, the Trustee, and any agent of the Company or the Trustee
as the owner of such global Security for all purposes whatsoever. None of the Company, the Trustee,
any Paying Agent or the Security Registrar will have any responsibility or

31

 

liability for any aspect of the records relating to or payments made on account of beneficial
ownership interests of a global Security or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests.

     Section 3.10. Cancellation.

     All Securities and Coupons surrendered for payment, redemption, registration of transfer,
exchange or conversion or for credit against any sinking fund payment shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee, and any such Securities and Coupons, as
well as Securities and Coupons surrendered directly to the Trustee for any such purpose, shall be
cancelled promptly by the Trustee. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder which the Company may
have acquired in any manner whatsoever, and all Securities so delivered shall be cancelled promptly
by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section 3.10, except as expressly permitted by or pursuant to
this Indenture. All cancelled Securities and Coupons held by the Trustee shall be destroyed by the
Trustee, unless by a Company Order the Company directs their return to it.

     Section 3.11. Computation of Interest.

     Except as otherwise provided in or pursuant to this Indenture or in any Security, interest on
the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

ARTICLE 4

Satisfaction and Discharge of Indenture

     Section 4.1. Satisfaction and Discharge.

     Upon the direction of the Company by a Company Order, this Indenture shall cease to be of
further effect with respect to any series of Securities specified in such Company Order and any
Coupons appertaining thereto, and the Trustee, on receipt of a Company Order, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and discharge of this
Indenture as to such series, when

     (1) either

     (a) all Securities of such series theretofore authenticated and delivered and all
Coupons appertaining thereto (other than (i) Coupons appertaining to Bearer Securities of
such series surrendered in exchange for Registered Securities of such series and maturing
after such exchange whose surrender is not required or has been waived as provided in
Section 3.5, (ii) Securities and Coupons of such series which have been destroyed,
lost or stolen and which have been replaced or paid as provided in Section 3.6,
(iii) Coupons appertaining to Securities of such series called for redemption and maturing
after the relevant Redemption Date whose surrender has been waived as provided in
Section 11.7, and (iv) Securities and Coupons of such series for whose payment money
has theretofore been deposited in trust or segregated and held in trust by the Company

32

 

and thereafter repaid to the Company or discharged from such trust, as provided in
Section 10.3) have been delivered to the Trustee for cancellation; or

     (b) all Securities of such series and, in the case of (i) or (ii) below, any Coupons
appertaining thereto not theretofore delivered to the Trustee for cancellation

     (i) have become due and payable, or

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

     (iii) if redeemable at the option of the Company, are to be called for
redemption within one year under arrangements satisfactory to the Trustee for the
giving of notice of redemption by the Trustee in the name, and at the expense, of
the Company, and the Company, in the case of (i), (ii) or (iii) above, has deposited
or caused to be deposited with the Trustee as trust funds in trust for such purpose,
money in the Currency in which such Securities are payable in an amount sufficient
to pay and discharge the entire indebtedness on such Securities and any Coupons
appertaining thereto not theretofore delivered to the Trustee for cancellation,
including the principal of, any premium and interest on, and any Additional Amounts
with respect to such Securities and any Coupons appertaining thereto, to the date of
such deposit (in the case of Securities which have become due and payable) or to the
Maturity thereof, as the case may be;

     (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company
with respect to the Outstanding Securities of such series and any Coupons appertaining thereto; and

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

     (a) In the event there are Securities of two or more series hereunder, the Trustee
shall be required to execute an instrument acknowledging satisfaction and discharge of this
Indenture only if requested to do so with respect to Securities of such series as to which
it is Trustee and if the other conditions thereto are met.

     Notwithstanding the satisfaction and discharge of this Indenture with respect to any series of
Securities, the obligations of the Company to the Trustee under Section 6.6 and, if money
shall have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this
Section 4.1, the obligations of the Company and the Trustee with respect to the Securities
of such series under Sections 3.5, 3.6, 4.3, 10.2 and 10.3,
with respect to the payment of Additional Amounts, if any, with respect to such Securities as
contemplated by Section 10.4 (but only to the extent that the Additional Amounts payable
with respect to such Securities exceed the amount deposited in respect of such Additional Amounts
pursuant to Section 4.1(1)(b)), and with respect to any rights to convert or exchange such
Securities into Common Stock of the Company or other securities shall survive.

33

 

     Section 4.2. Defeasance and Covenant Defeasance.

     (1) Unless pursuant to Section 3.1, either or both of (i) defeasance of the Securities
of or within a series under clause (2) of this Section 4.2 shall not be applicable with
respect to the Securities of such series or (ii) covenant defeasance of the Securities of or within
a series under clause (3) of this Section 4.2 shall not be applicable with respect
to the Securities of such series, then such provisions, together with the other provisions of this
Section 4.2 with such modifications thereto as may be specified pursuant to Section
3.1 with respect to any Securities), shall be applicable to such Securities and any Coupons
appertaining thereto, and the Company way at its option by Board Resolution, at any time, with
respect to securities and any Coupons appertaining thereto, elect to have Section 4.2(2) or
Section 4.2(3) be applied to such Outstanding Securities and any Coupons appertaining
thereto upon compliance with the conditions set forth below in this Section 4.2.

     (2) Upon the Company’s exercise of the above option applicable to this Section 4.2(2)
with respect to any Securities of or within a series, the Company shall be deemed to have been
discharged from its obligations with respect to such Outstanding Securities and any Coupons
appertaining thereto on the date the conditions set forth in clause (4) of this Section
4.2 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that
the Company shall be deemed to have paid and discharged the entire Indebtedness represented by such
Outstanding Securities and any Coupons appertaining thereto, which shall thereafter be deemed to be
“Outstanding” only for the purposes of clause (5) of this Section 4.2 and the other
Sections of this Indenture referred to in clauses (i) and (ii) below, and to have
satisfied all of its other obligations under such Securities and any Coupons appertaining thereto
and this Indenture insofar as such Securities and any Coupons appertaining thereto are concerned
(and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the
same), except for the following which shall survive until otherwise terminated or discharged
hereunder: (i) the rights of Holders of such Outstanding Securities and any Coupons appertaining
thereto to receive, solely from the trust fund described in clause (4) of this Section
4.2 and as more fully set forth in such clause, payments in respect of the principal of (and
premium, if any) and interest, if any, on, and Additional Amounts, if any, with respect to, such
Securities and any Coupons appertaining thereto when such payments are due, and any rights of such
Holder to convert such Securities into Common Stock of the Company or exchange such Securities for
other securities, (ii) the obligations of the Company and the Trustee with respect to such
Securities under Sections 3.5, 3.6, 10.2 and 10.3 and with respect
to the payment of Additional Amounts, if any, on such Securities as contemplated by Section
10.4 (but only to the extent that the Additional Amounts payable with respect to such
Securities exceed the amount deposited in respect of such Additional Amounts pursuant to
Section 4.2(4)(a) below), and with respect to any rights to convert such Securities into
Common Stock of the Company or exchange such Securities for other securities, (iii) the rights,
powers, trusts, duties and immunities of the Trustee hereunder and (iv) this Section 4.2.
The Company may exercise its option under this Section 4.2(2) notwithstanding the prior
exercise of its option under clause (3) of this Section 4.2 with respect to such
Securities and any Coupons appertaining thereto.

     (3) Upon the Company’s exercise of the option to have this Section 4.2(3) apply with
respect to any Securities of or within a series, the Company shall be released from its obligations
under Sections 10.5 and 10.6, and, to the extent specified pursuant to Section
3.1(19), any other

34

 

covenant applicable to such Securities, with respect to such Outstanding Securities and any
Coupons appertaining conditions set forth in clause (4) of this Section 4.2 are
satisfied (hereinafter, “covenant defeasance”), and such Securities and any Coupons appertaining
thereto shall thereafter be deemed to be not “Outstanding” for the purposes of any Act of Holders
(and the consequences of any thereof) in connection with any such covenant, but shall continue to
be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to such Outstanding Securities and any Coupons appertaining
thereto, the Company may omit to comply with, and shall have no liability in respect of, any term,
condition or limitation set forth in any such Section or such other covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant
or by reason of reference in any such Section or such other covenant to any other provision herein
or in any other document and such omission to comply shall not constitute a default or an Event of
Default under Section 5.1(4) or 5.1(9) or otherwise, as the case may be, but,
except as specified above, the remainder of this Indenture and such Securities and Coupons
appertaining thereto shall be unaffected thereby.

     (4) The following shall be the conditions to application of clause (2) or (3) of this
Section 4.2 to any Outstanding Securities of or within a series and any Coupons
appertaining thereto:

     (a) The Company shall irrevocably have deposited or caused to be deposited with the
Trustee (or another trustee satisfying the requirements of Section 6.7 who shall
agree to comply with the provisions of this Section 4.2 applicable to it) as trust
funds in trust for the purpose of making the following payments, specifically pledged as
security for, and dedicated solely to, the benefit of the Holders of such Securities and any
Coupons appertaining thereto, (1) an amount in Dollars or in such Foreign Currency in which
such Securities and any Coupons appertaining thereto are then specified as payable at Stated
Maturity, or (2) Government Obligations applicable to such Securities and Coupons
appertaining thereto (determined on the basis of the Currency in which such Securities and
Coupons appertaining thereto are then specified as payable at Stated Maturity) which through
the scheduled payment of principal and interest in respect thereof in accordance with their
terms will provide, not later than one day before the due date of any payment of principal
of (and premium, if any) and interest, if any, on such Securities and any Coupons
appertaining thereto, money in an amount, or (3) a combination thereof, in any case, in an
amount, sufficient, without consideration of any reinvestment of such principal and
interest, in the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee (or other qualifying trustee) to pay and
discharge, (y) the principal of (and premium, if any) and interest, if any, on such
Outstanding Securities and any Coupons appertaining thereto at the Stated Maturity of such
principal or installment of principal or premium or interest and (z) any mandatory sinking
fund payments or analogous payments applicable to such Outstanding Securities and any
Coupons appertaining thereto on the days on which such payments are due and payable in
accordance with the terms of this Indenture and of such Securities and any Coupons
appertaining thereto.

35

 

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

     (c) No Event of Default or event which with notice or lapse of time or both would
become an Event of Default with respect to such Securities and any Coupons appertaining
thereto shall have occurred and be continuing on the date of such deposit and, with respect
to defeasance only, at any time during the period ending on the 123rd day after the date of
such deposit (it being understood that this condition shall not be deemed satisfied until
the expiration of such period).

     (d) In the case of an election under clause (2) of this Section 4.2, the
Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the
Company has received from the Internal Revenue Service a letter ruling, or there has been
published by the Internal Revenue Service a Revenue Ruling, or (ii) since the date of
execution of this Indenture, there has been a change in the applicable Federal income tax
law, in either case to the effect that, and based thereon such opinion shall confirm that,
the Holders of such Outstanding Securities and any Coupons appertaining thereto will not
recognize income, gain or loss for Federal income tax purposes as a result of such
defeasance and will be subject to Federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such defeasance had not occurred.

     (e) In the case of an election under clause (3) of this Section 4.2, the
Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Outstanding Securities and any Coupons appertaining thereto will not
recognize income, gain or loss for Federal income tax purposes as a result of such covenant
defeasance and will be subject to Federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such covenant defeasance had not
occurred.

     (f) The Company shall have delivered to the Trustee an Opinion of Counsel to the effect
that, after the 123rd day after the date of deposit, all money and Government Obligations
(or other property as may be provided pursuant to Section 3.1) (including the
proceeds thereof) deposited or caused to be deposited with the Trustee (or other qualifying
trustee) pursuant to this clause (4) to be held in trust will not be subject to any case or
proceeding (whether voluntary or involuntary) in respect of the Company under any Federal or
State bankruptcy, insolvency, reorganization or other similar law, or any decree or order
for relief in respect of the Company issued in connection therewith.

     (g) The Company shall have delivered to the Trustee an Officer’s Certificate and an
Opinion of Counsel, each stating that all conditions precedent to the defeasance or covenant
defeasance under clause (2) or (3) of this Section 4.2 (as the case may be) have
been complied with.

     (h) Notwithstanding any other provisions of this Section 4.2(4), such
defeasance or covenant defeasance shall be effected in compliance with any additional or

36

 

substitute terms, conditions or limitations which may be imposed on the Company in
connection therewith pursuant to Section 3.1.

     (5) Unless otherwise specified in or pursuant to this Indenture or any Security, if, after a
deposit referred to in Section 4.2(4)(a) has been made, (a) the Holder of a Security in
respect of which such deposit was made is entitled to, and does, elect pursuant to Section
3.1 or the terms of such Security to receive payment in a Currency other than that in which the
deposit pursuant to Section 4.2(4)(a) has been made in respect of such Security, or (b) a
Conversion Event occurs in respect of the Foreign Currency in which the deposit pursuant to
Section 4.2(4)(a) has been made, the indebtedness represented by such Security and any
Coupons appertaining thereto shall be deemed to have been, and will be, fully discharged and
satisfied through the payment of the principal of (and premium, if any), and interest, if any, on,
and Additional Amounts, if any, with respect to, such Security as the same becomes due out of the
proceeds yielded by converting (from time to time as specified below in the case of any such
election) the amount or other property deposited in respect of such Security into the Currency in
which such Security becomes payable as a result of such election or Conversion Event based on (x)
in the case of payments made pursuant to clause (a) above, the applicable market exchange rate for
such Currency in effect on the second Business Day prior to each payment date, or (y) with respect
to a Conversion Event, the applicable market exchange rate for such Foreign Currency in effect (as
nearly as feasible) at the time of the Conversion Event.

     The Company shall pay and indemnify the Trustee (or other qualifying trustee, collectively for
purposes of this Section 4.2(5) and Section 4.3, the “Trustee”) against any tax,
fee or other charge, imposed on or assessed against the Government Obligations deposited pursuant
to this Section 4.2 or the principal or interest received in respect thereof other than any
such tax, fee or other charge which by law is for the account of the Holders of such Outstanding
Securities and any Coupons appertaining thereto.

     Anything in this Section 4.2 to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company from time to time upon Company Request any money or Government
Obligations (or other property and any proceeds therefrom) held by it as provided in clause (4) of
this Section 4.2 which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to effect a defeasance or
covenant defeasance, as applicable, in accordance with this Section 4.2.

     Section 4.3. Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 10.3, all money and
Government Obligations (or other property as may be provided pursuant to Section 3.1)
(including the proceeds thereof) deposited with the Trustee pursuant to Section 4.1 or 4.2
in respect of any Outstanding Securities of any series and any Coupons appertaining thereto shall
be held in trust and applied by the Trustee, in accordance with the provisions of such Securities
and any Coupons appertaining thereto and this Indenture, to the payment, either directly or through
any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities and any Coupons appertaining thereto of all sums due
and to become due thereon in respect of principal (and premium, if any) and

37

 

interest and Additional Amounts, if any; but such money and Government Obligations need not be
segregated from other funds except to the extent required by law.

     Section 5.2. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default with respect to Securities of any series at the time Outstanding (other
than an Event of Default specified in clause (7) or (8) of Section 5.1) occurs and is
continuing, then the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of such series may declare the principal of all the Securities of such
series, or such lesser amount as may be provided for in the Securities of such series, to be due
and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the
Holders), and upon any such declaration such principal or such lesser amount shall become
immediately due and payable.

     If an Event of Default specified in clause (7) or (8) of Section 5.1 occurs, all
unpaid principal of and accrued interest on the Outstanding Securities of that series (or such
lesser amount as may be provided for in the Securities of such series) shall ipso facto become and
be immediately due and payable without any declaration or other act on the part of the Trustee or
any Holder of any Security of that series.

     At any time after a declaration of acceleration with respect to the Securities of any series
has been made and before a judgment or decree for payment of the money due has been obtained by the
Trustee as hereinafter in this Article provided, the Holders of not less than a majority in
principal amount of the Outstanding Securities of such series, by written notice to the Company and
the Trustee, may rescind and annul such declaration and its consequences if

     (1) the Company has paid or deposited with the Trustee a sum of money sufficient to pay

     (a) all overdue installments of any interest on and Additional Amounts with respect to
all Securities of such series and any Coupon appertaining thereto,

     (b) the principal of and any premium on any Securities of such series which have become
due otherwise than by such declaration of acceleration and interest thereon and any
Additional Amounts with respect thereto at the rate or rates borne by or provided for in
such Securities,

     (c) to the extent that payment of such interest or Additional Amounts is lawful,
interest upon overdue installments of any interest and Additional Amounts at the rate or
rates borne by or provided for in such Securities, and sums paid or advanced by the Trustee
hereunder and the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel and all other amounts due the Trustee under Section
6.6; and

     (2) all Events of Default with respect to Securities of such series, other than the
non-payment of the principal of, any premium and interest on, and any Additional Amounts with
respect to Securities of such series which shall have become due solely by such declaration of
acceleration, shall have been cured or waived as provided in Section 5.13.

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

40

 

     Section 5.3. Collection of Indebtedness and Suits for Enforcement by Trustee.

               The Company covenants that if

     (1) default is made in the payment of any installment of interest on or any Additional Amounts
with respect to any Security or any Coupon appertaining thereto when such interest or Additional
Amounts shall have become due and payable and such default continues for a period of 30 days, or

     (2) default is made in the payment of the principal of or any premium on any Security or any
Additional Amounts with respect thereto at their Maturity,

the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders
of such Securities and any Coupons appertaining thereto, the whole amount of money then due and
payable with respect to such Securities and any Coupons appertaining thereto, with interest upon
the overdue principal, any premium and, to the extent that payment of such interest shall be
legally enforceable, upon any overdue installments of interest and Additional Amounts at the rate
or rates borne by or provided for in such Securities, and, in addition thereto, such further amount
of money as shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel and all other amounts due to the Trustee under Section 6.6.

     If the Company fails to pay the money it is required to pay the Trustee pursuant to the
preceding paragraph forthwith upon the demand of the Trustee, the Trustee, in its own name and as
trustee of an express trust, may institute a judicial proceeding for the collection of the money so
due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the
same against the Company or any other obligor upon such Securities and any Coupons appertaining
thereto and collect the monies adjudged or decreed to be payable in the manner provided by law out
of the property of the Company or any other obligor upon such Securities and any Coupons
appertaining thereto, wherever situated.

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

     Section 5.4. Trustee May File Proofs of Claim.

     In case of the pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the
Company or any other obligor upon the Securities of any series or the property of the Company or
such other obligor or their creditors, the Trustee (irrespective of whether the principal of the
Securities shall then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand on the Company for the

41

 

payment of any overdue principal, premium, interest or Additional Amounts) shall be entitled
and empowered, by intervention in such proceeding or otherwise,

     (1) to file and prove a claim for the whole amount, or such lesser amount as may be provided
for in the Securities of any applicable series, of the principal and any premium, interest and
Additional Amounts owing and unpaid in respect of the Securities and any Coupons appertaining
thereto and to file such other papers or documents as may be necessary or advisable in order to
have the claims of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents or counsel) and of the Holders of Securities
or any Coupons appertaining thereto allowed in such judicial proceeding, and

     (2) to collect and receive other property payable or deliverable on any such claims and to
distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by each Holder of
Securities or any Coupons to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders of Securities or any Coupons,
to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under
Section 6.6.

     Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Holder of a Security or any Coupon any plan of reorganization,
arrangement, adjustment or composition affecting the Securities or Coupons or the rights of any
Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a
Security or any Coupon in any such proceeding.

     Section 5.5. Trustee May Enforce Claims without Possession of Securities or Coupons.

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

     Section 5.6. Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article shall be applied in the following
order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on
account of principal, or any premium, interest or Additional Amounts, upon presentation of the
Securities or Coupons, or both, as the case may be, and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee and any predecessor Trustee under
Section 6.6;

42

 

     SECOND: To the payment of the amounts then due and unpaid upon the Securities and any Coupons
for principal and any premium, interest and Additional Amounts in respect of which or for the
benefit of which such money has been collected, ratably, without preference or priority of any
kind, according to the aggregate amounts due and payable on such Securities and Coupons for
principal and any premium, interest and Additional Amounts, respectively;

     THIRD: The balance, if any, to the Person or Persons entitled thereto.

     Section 5.7. Limitations on Suits.

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

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

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

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

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

     (5) no direction inconsistent with such written request has been given to the Trustee during
such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities
of such series;

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

     Section 5.8. Unconditional Right of Holders to Receive Principal and any Premium, Interest
and Additional Amounts.

     Notwithstanding any other provision in this Indenture, the Holder of any Security or Coupon
shall have the right, which is absolute and unconditional, to receive payment of the principal of,
any premium and (subject to Sections 3.5 and 3.7) interest on, and any Additional
Amounts with respect to such Security or payment of such Coupon, as the case may be, on the
respective Stated Maturity or Maturities therefor specified in such Security or Coupon (or, in the
case of redemption, on the Redemption Date or, in the case of repayment at the option of such

43

 

Holder if provided in or pursuant to this Indenture, on the date such repayment is due) and to
institute suit for the enforcement of any such payment, and such right shall not be impaired
without the consent of such Holder.

     Section 5.9. Restoration of Rights and Remedies.

     If the Trustee or any Holder of a Security or a Coupon has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been discontinued or
abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then
and in every such case the Company, the Trustee and each such Holder shall, subject to any
determination in such proceeding, be restored severally and respectively to their former positions
hereunder, and thereafter all rights and remedies of the Trustee and each such Holder shall
continue as though no such proceeding had been instituted.

     Section 5.10. Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities or Coupons in the last paragraph of Section 3.6, no
right or remedy herein conferred upon or reserved to the Trustee or to each and every Holder of a
Security or a Coupon is intended to be exclusive of any other right or remedy, and every right and
remedy, to the extent permitted by law, shall 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, to the extent
permitted by law, prevent the concurrent assertion or employment of any other appropriate right or
remedy.

     Section 5.11. Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Security or Coupon to exercise any
right or remedy accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy
given by this Article or by law to the Trustee or to any Holder of a Security or a Coupon may be
exercised from time to time, and as often as may be deemed expedient, by the Trustee or by such
Holder, as the case may be.

     Section 5.12. Control by Holders of Securities.

     The Holders of a majority in principal amount of the Outstanding Securities of any series
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 and any Coupons appertaining thereto, provided that

     (1) such direction shall not be in conflict with any rule of law or with this Indenture or
with the Securities of such series,

     (2) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction, and

44

 

     (3) such direction is not unduly prejudicial to the rights of the other Holders of Securities
of such series not joining in such action.

     Section 5.13. Waiver of Past Defaults.

     The Holders of not less than a majority in principal amount of the Outstanding Securities of
any series on behalf of the Holders of all the Securities of such series and any Coupons
appertaining thereto may waive any past default hereunder with respect to such series and its
consequences, except a default

     (1) in the payment of the principal of, any premium or interest on, or any Additional Amounts
with respect to, any Security of such series or any Coupons appertaining thereto, or

     (2) in respect of a covenant or provision hereof which under Article 9 cannot be modified or
amended without the consent of the Holder of each Outstanding Security of such series affected.

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

     Section 5.14. Waiver of Usury, Stay or Extension Laws.

The Company covenants that (to the extent that it may lawfully do so) it will not at any time
insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any
usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company expressly waives (to the
extent that it may lawfully do so) all benefit or advantage of any such law and covenants that it
will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will
suffer and permit the execution of every such power as though no such law had been enacted.

     Section 5.15. Undertaking for Costs

     All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof
shall be deemed to have agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any
action taken or omitted by it as Trustee, the filing by any party litigant in such suit of any
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 5.15 shall not apply to any suit instituted by
the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of Outstanding Securities of any series, or to any suit
instituted by any Holder for the enforcement of the payment of the principal of (or premium, if
any) or interest, if any, on or Additional Amounts, if any, with respect to any Security on or
after the respective Stated Maturities expressed in such Security (or, in the case of redemption,
on or after the Redemption Date, and, in the case of repayment, on or after the date for repayment)
or for the

45

 

enforcement of the right, if any, to convert or exchange any Security into Common Stock or
other securities in accordance with its terms.

fund installment with respect to, any Security of 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 and/or Responsible Officers of the Trustee in good faith determine
that the withholding of such notice is in the best interest of the Holders of Securities and
Coupons of such series; and provided, further, that in the case of any default of the character
specified in Section 5.1(5) with respect to Securities of such series, no such notice to
Holders shall be given until at least 30 days after the occurrence thereof. For the purpose of
this Section 6.2, the term “default” means any event which is, or after notice or lapse of
time or both would become, an Event of Default with respect to Securities of such series.

     Section 6.3. Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Securities, except the Trustee’s certificate of
authentication, and in any Coupons shall be taken as the statements of the Company and neither the
Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee
makes no representations as to the validity or sufficiency of this Indenture or of the Securities
or the Coupons, except that the Trustee represents that it is duly authorized to execute and
deliver this Indenture, authenticate the Securities and perform its obligations hereunder and

47

 

that the statements made by it in a Statement of Eligibility on Form T-1 supplied to the
Company are true and accurate, subject to the qualifications set forth therein. Neither the Trustee
nor any Authenticating Agent shall be accountable for the use or application by the Company of the
Securities or the proceeds thereof.

     Section 6.4. May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other
Person that may be an agent of the Trustee or the Company, in its individual or any other capacity,
may become the owner or pledgee of Securities or Coupons and, subject to Sections 310(b)
and 311 of the Trust Indenture Act, may otherwise deal with the Company with the same
rights it would have if it were not the Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other Person.

     Section 6.5. Money Held in Trust.

     Except as provided in Sections 4.3 and 10.3, money held by the Trustee in
trust hereunder need not be segregated from other funds except to the extent required by law and
shall be held uninvested. The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed to in writing with the Company.

     Section 6.6. Compensation and Reimbursement.

     The Company agrees:

     (1) to pay to the Trustee from time to time reasonable compensation for all services rendered
by the Trustee hereunder (which compensation shall not be limited by any provision of law in regard
to the compensation of a trustee of an express trust);

     (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request
for all reasonable expenses, disbursements and advances incurred or made by the Trustee in
accordance with any provision of this Indenture or arising out of or in connection with the
acceptance or administration of the trust or trusts hereunder (including the reasonable
compensation and the expenses and disbursements of its agents and counsel), except any such
expense, disbursement or advance as may be attributable to the Trustee’s negligence or bad faith;
and

     (3) to indemnify the Trustee and its agents, officers, directors and employees for, and to
hold them harmless against, any loss, liability or expense incurred without negligence or bad faith
on their part, arising out of or in connection with the acceptance or administration of the trust
or trusts hereunder, including the costs and expenses of defending themselves against any claim or
liability in connection with the exercise or performance of any of their powers or duties
hereunder, except to the extent that any such loss, liability or expense was due to the Trustee’s
negligence or bad faith.

     As security for the performance of the obligations of the Company under this Section
6.6, the Trustee shall have a lien prior to the Securities of any series upon all property and
funds held or collected by the Trustee as such, except funds held in trust for the payment of
principal of, and

48

 

premium or interest on or any Additional Amounts with respect to Securities or any Coupons
appertaining thereto.

     To the extent permitted by law, any compensation or expense incurred by the Trustee after a
default specified in or pursuant to Section 5.1 is intended to constitute an expense of
administration under any then applicable bankruptcy or insolvency law. “Trustee” for purposes of
this Section 6.6 shall include any predecessor Trustee but the negligence or bad faith of
any Trustee shall not affect the rights of any other Trustee under this Section 6.6.

     The provisions of this Section 6.6 shall survive the satisfaction and discharge of
this Indenture or the earlier resignation or removal of the Trustee and shall apply with equal
force and effect to the Trustee in its capacity as Authenticating Agent, Paying Agent or Security
Registrar.

     Section 6.7. Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee hereunder that is a Corporation organized and doing
business under the laws of the United States of America, any state thereof or the District of
Columbia, that is eligible under Section 310(a)(1) of the Trust Indenture Act to act as
trustee under an indenture qualified under the Trust Indenture Act and that has a combined capital
and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of
at least $50,000,000, and that is subject to supervision or examination by Federal or state
authority. If at any time the Trustee shall cease to be eligible in accordance with the provisions
of this Section 6.7, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

     Section 6.8. Resignation and Removal; Appointment of Successor.

     (1) No resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this Article shall become effective until the acceptance of appointment by the
successor Trustee pursuant to Section 6.9.

     (2) The Trustee may resign at any time with respect to the Securities of one or more series by
giving written notice thereof to the Company. If the instrument of acceptance by a successor
Trustee required by Section 6.9 shall not have been delivered to the Trustee within 30 days
after the giving of such notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect to such series.

     (3) The Trustee may be removed at any time with respect to the Securities of any series by Act
of the Holders of a majority in principal amount of the Outstanding Securities of such series,
delivered to the Trustee and the Company.

     (4) If at any time:

     (a) the Trustee shall fail to comply with the obligations imposed upon it under
Section 310(b) of the Trust Indenture Act with respect to Securities of any series
after written request therefor by the Company or any Holder of a Security of such series who
has been a bona fide Holder of a Security of such series for at least six months, or

49

 

     (b) the Trustee shall cease to be eligible under Section 6.7 and shall fail to
resign after written request therefor by the Company or any such Holder, or

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

     then, in any such case, (i) the Company, by or pursuant to a Board Resolution, may remove the
Trustee with respect to all Securities or the Securities of such series, or (ii) subject to
Section 315(e) of the Trust Indenture Act, any Holder of a Security who has been a bona
fide Holder of a Security of such series for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the removal of the
Trustee with respect to all Securities of such series and the appointment of a successor Trustee or
Trustees.

     (5) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy
shall occur in the office of Trustee for any cause, with respect to the Securities of one or more
series, the Company, by or pursuant to a Board Resolution, shall promptly appoint a successor
Trustee or Trustees with respect to the Securities of such series (it being understood that any
such successor Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to the Securities of
any particular series) and shall comply with the applicable requirements of Section 6.9.
If, within one year after such resignation, removal or incapacity, or the occurrence of such
vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act
of the Holders of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment in accordance with the applicable requirements of
Section 6.9, become the successor Trustee with respect to the Securities of such series and
to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee
with respect to the Securities of any series shall have been so appointed by the Company or the
Holders of Securities and accepted appointment in the manner required by Section 6.9, any
Holder of a Security who has been a bona fide Holder of a Security of such series for at least six
months may, on behalf of himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Securities of such
series.

     (6) The Company shall give notice of each resignation and each removal of the Trustee with
respect to the Securities of any series and each appointment of a successor Trustee with respect to
the Securities of any series by mailing written notice of such event by first-class mail, postage
prepaid, to the Holders of Registered Securities, if any, of such series as their names and
addresses appear in the Security Register and, if Securities of such series are issued as Bearer
Securities, by publishing notice of such event once in an Authorized Newspaper in each Place of
Payment located outside the United States. Each notice shall include the name of the successor
Trustee with respect to the Securities of such series and the address of its Corporate Trust
Office.

50

 

     (7) In no event shall any retiring Trustee be liable for the acts or omissions of any
successor Trustee hereunder.

     Section 6.9. Acceptance of Appointment by Successor.

     (1) Upon the appointment hereunder of any successor Trustee with respect to all Securities,
such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and the
retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, trusts and duties hereunder of
the retiring Trustee; but, on the request of the Company or such successor Trustee, such retiring
Trustee, upon payment of its charges, shall execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and, subject to
Section 10.3, shall duly assign, transfer and deliver to such successor Trustee all
property and money held by such retiring Trustee hereunder, subject nevertheless to its claim, if
any, provided for in Section 6.6.

     (2) Upon the appointment hereunder of any successor Trustee with respect to the Securities of
one or more (but not all) series, the Company, the retiring Trustee and such successor Trustee
shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall
accept such appointment and which (1) shall contain such provisions as shall be necessary or
desirable to transfer and confirm to, and to vest in, such successor Trustee all the rights,
powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is
not retiring with respect to all Securities, shall contain such provisions as shall be deemed
necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series as to which the retiring Trustee is
not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change
any of the provisions of this Indenture as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one Trustee, it being understood that nothing
herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same
trust, that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart
from any trust or trusts hereunder administered by any other such Trustee and that no Trustee shall
be responsible for any notice given to, or received by, or any act or failure to act on the part of
any other Trustee hereunder, and, upon the execution and delivery of such supplemental indenture,
the resignation or removal of the retiring Trustee shall become effective to the extent provided
therein, such retiring Trustee shall have no further responsibility for the exercise of rights and
powers or for the performance of the duties and obligations vested in the Trustee under this
Indenture with respect to the Securities of that or those series to which the appointment of such
successor Trustee relates other than as hereinafter expressly set forth, and such successor
Trustee, without any further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates; but, on request of the Company
or such successor Trustee, such retiring Trustee, upon payment of its charges with respect to the
Securities of that or those series to which the appointment of such successor Trustee relates and
subject to Section 10.3 shall duly assign, transfer and deliver to such successor Trustee,
to the extent contemplated by such supplemental indenture, the property and

51

 

money held by such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates, subject to its claim, if any,
provided for in Section 6.6.

     (3) Upon request of any Person appointed hereunder as a successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and confirming to such
successor Trustee all such rights, powers and trusts referred to in paragraph (1) or (2) of this
Section 6.9, as the case may be.

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

     Section 6.10. Merger, Conversion, Consolidation or Succession to Business.

     Any Corporation into which the Trustee may be merged or converted or with which it may be
consolidated, or any Corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, shall be the successor of the Trustee hereunder, without the
execution or filing of any paper or any further act on the part of any of the parties hereto. In
case any Securities shall have been authenticated but not delivered by the Trustee then in office,
any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect as if such
successor Trustee had itself authenticated such Securities.

     Section 6.11. Appointment of Authenticating Agent.

     The Trustee may appoint one or more Authenticating Agents acceptable to the Company with
respect to one or more series of Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities of that or those series issued upon original issue, exchange,
registration of transfer, partial redemption or partial repayment or pursuant to Section
3.6, and Securities so authenticated shall be entitled to the benefits of this Indenture and
shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder.
Wherever reference is made in this Indenture to the authentication and delivery of Securities by
the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a
certificate of authentication executed on behalf of the Trustee by an Authenticating Agent.

     Each Authenticating Agent must be acceptable to the Company and, except as provided in or
pursuant to this Indenture, shall at all times be a corporation that would be permitted by the
Trust Indenture Act to act as trustee under an indenture qualified under the Trust Indenture Act,
is authorized under applicable law and by its charter to act as an Authenticating Agent and has a
combined capital and surplus (computed in accordance with Section 310(a)(2) of the Trust
Indenture Act) of at least $50,000,000. If at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section 6.11, it shall resign
immediately in the manner and with the effect specified in this Section 6.11.

     Any Corporation into which an Authenticating Agent may be merged or converted or with which it
may be consolidated, or any Corporation resulting from any merger, conversion or

52

 

consolidation to which such Authenticating Agent shall be a party, or any Corporation
succeeding to all or substantially all of the corporate agency or corporate trust business of an
Authenticating Agent, shall be the successor of such Authenticating Agent hereunder, provided such
Corporation shall be otherwise eligible under this Section 6.11, without the execution or
filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
and the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by
giving written notice thereof to such Authenticating Agent and the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section 6.11, the
Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and
shall (i) mail written notice of such appointment by first-class mail, postage prepaid, to all
Holders of Registered Securities, if any, of the series with respect to which such Authenticating
Agent shall serve, as their names and addresses appear in the Security Register, and (ii) if
Securities of the series are issued as Bearer Securities, publish notice of such appointment at
least once in an Authorized Newspaper in the place where such successor Authenticating Agent has
its principal office if such office is located outside the United States. Any successor
Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all
the rights, powers and duties of its predecessor hereunder, with like effect as if originally named
as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible
under the provisions of this Section 6.11.

     The Company agrees to pay each Authenticating Agent from time to time reasonable compensation
for its services under this Section 6.11. If the Trustee makes such payments, it shall be
entitled to be reimbursed for such payments, subject to the provisions of Section 6.6.

     The provisions of Sections 3.8, 6.3 and 6.4 shall be applicable to
each Authenticating Agent.

     If an Authenticating Agent is appointed with respect to one or more series of Securities
pursuant to this Section 6.11, the Securities of such series may have endorsed thereon, in
addition to or in lieu of the Trustee’s certificate of authentication, an alternate certificate of
authentication in substantially the following form:

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

	 	 	 	 	 	 	 
	 

	 	[                    ],	 	 
	 

	 	as Trustee	 	 
	 
	 	 	 	 	 	 
	 

	 	By:	 	 	 	 
	 	 	 	 	 	 
	 

	 	 	 	as Authenticating Agent	 	 
	 
	 	 	 	 	 	 
	 

	 	By:	 	 	 	 
	 	 	 	 	 	 
	 

	 	 	 	as Authorized Officer	 	 

53

 

     If all of the Securities of any series may not be originally issued at one time, and if the
Trustee does not have an office capable of authenticating Securities upon original issuance located
in a Place of Payment where the Company wishes to have Securities of such series authenticated upon
original issuance, the Trustee, if so requested in writing (which writing need not be accompanied
by or contained in an Officer’s Certificate by the Company), shall appoint in accordance with this
Section 6.11 an Authenticating Agent having an office in a Place of Payment designated by
the Company with respect to such series of Securities.

     (12) to amend or supplement any provision contained herein or in any supplemental indenture,
provided that no such amendment or supplement shall materially adversely affect the interests of
the Holders of any Securities then Outstanding.

     Section 9.2. Supplemental Indentures with Consent of Holders.

     With the consent of the Holders of not less than a majority in principal amount of the
Outstanding Securities of each series affected by such supplemental indenture, by Act of said
Holders delivered to the Company and the Trustee, the Company (when authorized by or pursuant to a
Company’s Board Resolution) and the Trustee may 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 modifying in any manner the rights of the Holders of
Securities of such series under this Indenture or of the Securities of such series; provided,
however, that no such supplemental indenture, without the consent of the Holder of each Outstanding
Security affected thereby, shall

     (1) change the Stated Maturity of the principal of, or any premium or installment of interest
on or any Additional Amounts with respect to, any Security, or reduce the principal amount thereof
or the rate (or modify the calculation of such rate) of interest thereon or any Additional Amounts
with respect thereto, or any premium payable upon the redemption thereof or otherwise, or change
the obligation of the Company to pay Additional Amounts pursuant to Section 10.4 (except as
contemplated by Section 8.1(1) and permitted by Section 9.1(1)), or reduce the
amount of the principal of an Original Issue Discount Security that would be due and payable upon a
declaration of acceleration of the Maturity thereof pursuant to Section 5.2 or the amount
thereof provable in bankruptcy pursuant to Section 5.4, change the redemption provisions or
adversely affect the right of repayment at the option of any Holder as contemplated by Article 13,
or change the Place of Payment, Currency in which the principal of, any premium or interest on, or
any Additional Amounts with respect to any Security is payable, or impair the right to institute
suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the
case of redemption, on or after the Redemption Date or, in the case of repayment at the option of
the Holder, on or after the date for repayment), or

     (2) reduce the percentage in principal amount of the Outstanding Securities of any series, the
consent of whose Holders is required for any such supplemental indenture, or the consent of whose
Holders is required for any waiver (of compliance with certain provisions of

58

 

this Indenture or certain defaults hereunder and their consequences) provided for in this
Indenture, or reduce the requirements of Section 15.4 for quorum or voting, or

     (3) modify any of the provisions of this Section 9.2, Section 5.13 or
Section 10.8, except to increase any such percentage or to provide that certain other
provisions of this Indenture cannot be modified or waived without the consent of the Holder of each
Outstanding Security affected thereby, or

     (4) make any change that adversely affects the right to convert or exchange any Security into
or for Common Stock of the Company or other securities (whether or not issued by the Company), cash
or property in accordance with its terms.

     A supplemental indenture which changes or eliminates any covenant or other provision of this
Indenture which shall have been included expressly and solely for the benefit of one or more
particular series of Securities, or which modifies the rights of the Holders of Securities of such
series with respect to such covenant or other provision, shall be deemed not to affect the rights
under this Indenture of the Holders of Securities of any other series.

     It shall not be necessary for any Act of Holders of Securities under this Section 9.2
to approve the particular form of any proposed supplemental indenture, but it shall be sufficient
if such Act shall approve the substance thereof.

     Section 9.3. Execution of Supplemental Indentures.

     As a condition to executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modifications thereby of the trust created by this
Indenture, the Trustee shall be entitled to receive, and (subject to Section 315 of the
Trust Indenture Act) shall be fully protected in relying upon, an Opinion of Counsel stating that
the execution of such supplemental indenture is authorized or permitted by this Indenture and an
Officer’s Certificate stating that all conditions precedent to the execution of such supplemental
indenture have been fulfilled. The Trustee may, but shall not be obligated to, enter into any such
supplemental indenture which affects the Trustee’s own rights, duties or immunities under this
Indenture or otherwise.

     Section 9.4. Effect of Supplemental Indentures.

     Upon the execution of any supplemental indenture under this Article, this Indenture shall be
modified in accordance therewith, and such supplemental indenture shall form a part of this

     Section 9.5. Reference in Securities to Supplemental Indentures.

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

59

 

may be prepared and executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.

     Section 9.6. Conformity with Trust Indenture Act.

     Every supplemental indenture executed pursuant to this Article shall conform to the

     Section 9.7. Notice of Supplemental Indenture.

ARTICLE 10

Covenants

     Section 10.1. Payment of Principal, any Premium, Interest and Additional Amounts.

     The Company covenants and agrees for the benefit of the Holders of the Securities of each
series that it will duly and punctually pay the principal of, any premium and interest on and any
Additional Amounts with respect to the Securities of such series in accordance with the terms
thereof, any Coupons appertaining thereto and this Indenture. Any interest due on any Bearer
Security on or before the Maturity thereof, and any Additional Amounts payable with respect to such
interest, shall be payable only upon presentation and surrender of the Coupons appertaining thereto
for such interest as they severally mature.

     Section 10.2. Maintenance of Office or Agency.

     The Company shall maintain in each Place of Payment for any series of Securities an Office or
Agency where Securities of such series (but not Bearer Securities, except as otherwise provided
below, unless such Place of Payment is located outside the United States) may be presented or
surrendered for payment, where Securities of such series may be surrendered for registration of
transfer or exchange, where Securities of such series that are convertible or exchangeable may be
surrendered for conversion or exchange, and where notices and demands to or upon the Company in
respect of the Securities of such series relating thereto and this Indenture may be served. If
Securities of a series are issuable as Bearer Securities, the Company shall maintain, subject to
any laws or regulations applicable thereto, an Office or Agency in a Place of Payment for such
series which is located outside the United States where Securities of such series and any Coupons
appertaining thereto may be presented and surrendered for payment; provided, however, that if the
Securities of such series are listed on The Stock Exchange of the United Kingdom and the Republic
of Ireland or the Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock exchange shall so require, the Company shall maintain a Paying Agent in
London, Luxembourg or any other required city located outside the United States, as the case may
be, so long as the Securities of such series are listed on such exchange. The Company will give
prompt written notice to the Trustee of the location, and any change in the location, of such
Office or Agency. If at any time

60

 

the Company shall fail to maintain any such required Office or Agency or shall fail to furnish
the Trustee with the address thereof, such presentations, surrenders, notices and demands may be
made or served at the Corporate Trust Office of the Trustee, except that Bearer Securities of such
series and any Coupons appertaining thereto may be presented and surrendered for payment at the
place specified for the purpose with respect to such Securities as provided in or pursuant to this
Indenture, and the Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

     Except as otherwise provided in or pursuant to this Indenture, no payment of principal,
premium, interest or Additional Amounts with respect to Bearer Securities shall be made at any
Office or Agency in the United States or by check mailed to any address in the United States or by
transfer to an account maintained with a bank located in the United States; provided, however, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars, payment of
principal of, any premium or interest on and any Additional Amounts with respect to any such
Security may be made at the Corporate Trust Office of the Trustee or any Office or Agency
designated by the Company in the Borough of Manhattan, The City of New York, if (but only if)
payment of the full amount of such principal, premium, interest or Additional Amounts at all
offices outside the United States maintained for such purpose by the Company in accordance with
this Indenture is illegal or effectively precluded by exchange controls or other similar
restrictions.

     The Company may also from time to time designate one or more other Offices or Agencies where
the Securities of one or more series may be presented or surrendered for any or all such purposes
and may from time to time rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain an Office or
Agency in each Place of Payment for Securities of any series for such purposes. The Company shall
give prompt written notice to the Trustee of any such designation or rescission and of any change
in the location of any such other Office or Agency. Unless otherwise provided in or pursuant to
this Indenture, the Company hereby designates as the Place of Payment for each series of Securities
the Borough of Manhattan, The City of New York, and initially appoints the Corporate Trust Office
of the Trustee as the Office or Agency of the Company in the Borough of Manhattan, The City of New
York for such purpose. The Company may subsequently appoint a different Office or Agency in the
Borough of Manhattan, The City of New York for the Securities of any series.

     Unless otherwise specified with respect to any Securities pursuant to Section 3.1, if
and so long as the Securities of any series (i) are denominated in a Foreign Currency or (ii) may
be payable in a Foreign Currency, or so long as it is required under any other provision of this
Indenture, then the Company will maintain with respect to each such series of Securities, or as so
required, at least one exchange rate agent.

     Section 10.3. Money for Securities Payments to Be Held in Trust.

     If the Company shall at any time act as its own Paying Agent with respect to any series of
Securities, it shall, on or before each due date of the principal of, any premium or interest on or
Additional Amounts with respect to any of the Securities of such series, segregate and hold in
trust for the benefit of the Persons entitled thereto a sum in the currency or currencies, currency

61

 

unit or units or composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such
series) sufficient to pay the principal or any premium, interest or Additional Amounts so becoming
due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and
shall promptly notify the Trustee of its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents for any series of Securities, it
shall, on or prior to each due date of the principal of, any premium or interest on or any
Additional Amounts with respect to any Securities of such series, deposit with any Paying Agent a
sum (in the currency or currencies, currency unit or units or composite currency or currencies
described in the preceding paragraph) sufficient to pay the principal or any premium, interest or
Additional Amounts so becoming due, such sum to be held in trust for the benefit of the Persons
entitled thereto, and (unless such Paying Agent is the Trustee) the Company will promptly notify
the Trustee of its action or failure so to act.

     The Company shall cause each Paying Agent for any series of Securities other than the Trustee
to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the
Trustee, subject to the provisions of this Section 10.3, that such Paying Agent shall:

     (1) hold all sums held by it for the payment of the principal of, any premium or interest on
or any Additional Amounts with respect to Securities of such series in trust for the benefit of the
Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as
provided in or pursuant to this Indenture;

     (2) give the Trustee notice of any default by the Company (or any other obligor upon the
Securities of such series) in the making of any payment of principal, any premium or interest on or
any Additional Amounts with respect to the Securities of such series; and

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

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

     Except as otherwise provided herein or pursuant hereto, any money deposited with the Trustee
or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, any
premium or interest on or any Additional Amounts with respect to any Security of any series or any
Coupon appertaining thereto and remaining unclaimed for two years after such principal or any such
premium or interest or any such Additional Amounts shall have become due and payable shall be paid
to the Company on Company Request, or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Security or any Coupon appertaining thereto shall thereafter, as an
unsecured general creditor, look only to the

62

 

Company for payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being required to make any
such repayment, may at the expense of the Company cause to be published once, in an Authorized
Newspaper in each Place of Payment for such series or to be mailed to Holders of Registered
Securities of such series, or both, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such publication or
mailing nor shall it be later than two years after such principal and any premium or interest or
Additional Amounts shall have become due and payable, any unclaimed balance of such money then
remaining will be repaid to the Company.

     Section 10.4. Additional Amounts.

     All payments of principal of and premium, if any, interest and any other amounts on, or in
respect of, the Securities of any series or any Coupon appertaining thereto shall be made without
withholding or deduction at source for, or on account of, any present or future taxes, fees,
duties, assessments or governmental charges of whatever nature imposed or levied by or on behalf of
the Cayman Islands (a “taxing jurisdiction”) or any political subdivision or taxing authority
thereof or therein, unless such taxes, fees, duties, assessments or governmental charges are
required to be withheld or deducted by (i) the laws (or any regulations or ruling promulgated
thereunder) of a taxing jurisdiction or any political subdivision or taxing authority thereof or
therein or (ii) an official position regarding the application, administration, interpretation or
enforcement of any such laws, regulations or rulings (including, without limitation, a holding by a
court of competent jurisdiction or by a taxing authority in a taxing jurisdiction or any political
subdivision thereof). If a withholding or deduction at source is required, the Company shall,
subject to certain limitations and exceptions set forth below, pay to the Holder of any such
Security or any Coupon appertaining thereto such Additional Amounts as may be necessary so that
every net payment of principal, premium, if any, interest or any other amount made to such Holder,
after such withholding or deduction, shall not be less than the amount provided for in such
Security, any Coupons appertaining thereto and this Indenture to be then due and payable; provided,
however, that the Company shall not be required to make payment of such Additional Amounts for or
on account of:

     (1) any tax, fee, duty, assessment or governmental charge of whatever nature which would not
have been imposed but for the fact that such Holder: (A) was a resident, domiciliary or national
of, or engaged in business or maintained a permanent establishment or was physically present in,
the relevant taxing jurisdiction or any political subdivision thereof or otherwise had some
connection with the relevant taxing jurisdiction other than by reason of the mere ownership of, or
receipt of payment under, such Security; (B) presented such Security for payment in the relevant
taxing jurisdiction or any political subdivision thereof, unless such Security could not have been
presented for payment elsewhere; or (C) presented such Security more than thirty (30) days after
the date on which the payment in respect of such Security first became due and payable or provided
for, whichever is later, except to the extent that the Holder would have been entitled to such
Additional Amounts if it had presented such Security for payment on any day within such period of
thirty (30) days;

63

 

     (2) any estate, inheritance, gift, sale, transfer, personal property or similar tax,
assessment or other governmental charge;

     (3) any tax, assessment or other governmental charge that is imposed or withheld by reason of
the failure by the Holder or the beneficial owner of such Security to comply with any reasonable
request by the Company addressed to the Holder within 90 days of such request (A) to provide
information concerning the nationality, residence or identity of the Holder or such beneficial
owner or (B) to make any declaration or other similar claim or satisfy any information or
reporting requirement, which, in the case of (A) or (B), is required or imposed by statute, treaty,
regulation or administrative practice of the relevant taxing jurisdiction or any political
subdivision thereof as a precondition to exemption from all or part of such tax, assessment or
other governmental charge; or

     (4) any combination of items (1), (2) and (3);

nor shall Additional Amounts be paid with respect to any payment of the principal of, or premium,
if any, interest or any other amounts on, any such Security to any Holder who is a fiduciary or
partnership or other than the sole beneficial owner of such Security to the extent such payment
would be required by the laws of the relevant taxing jurisdiction (or any political subdivision or
relevant taxing authority thereof or therein) to be included in the income for tax purposes of a
beneficiary or partner or settlor with respect to such fiduciary or a member of such partnership or
a beneficial owner who would not have been entitled to such Additional Amounts had it been the
Holder of the Security.

     Whenever in this Indenture there is mentioned, in any context, the payment of the principal of
or any premium, interest or any other amounts on, or in respect of, any Security of any series or
any Coupon or the net proceeds received on the sale or exchange of any Security of any series, such
mention shall be deemed to include mention of the payment of Additional Amounts provided by the
terms of such series established hereby or pursuant hereto to the extent that, in such context,
Additional Amounts are, were or would be payable in respect thereof pursuant to such terms, and
express mention of the payment of Additional Amounts (if applicable) in any provision hereof shall
not be construed as excluding the payment of Additional Amounts in those provisions hereof where
such express mention is not made.

     Except as otherwise provided in or pursuant to this Indenture or the Securities of the
applicable series, at least 10 days prior to the first Interest Payment Date with respect to a
series of Securities (or if the Securities of such series shall not bear interest prior to
Maturity, the first day on which a payment of principal is made), and at least 10 days prior to
each date of payment of principal or interest if there has been any change with respect to the
matters set forth in the below-mentioned Officer’s Certificate, the Company shall furnish to the
Trustee and the principal Paying Agent or Paying Agents, if other than the Trustee, an Officer’s
Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of
principal of and premium, if any, interest or any other amounts on the Securities of such series
shall be made to Holders of Securities of such series or the Coupons appertaining thereto without
withholding for or on account of any tax, fee, duty, assessment or other governmental charge
described in this Section 10.4. If any such withholding shall be required, then such
Officer’s Certificate shall specify by taxing jurisdiction the amount, if any, required to be
withheld on such

64

 

payments to such Holders of Securities or Coupons, and the Company agrees to pay to the Trustee or such
Paying Agent the Additional Amounts required by this Section 10.4. The Company covenants to
indemnify the Trustee and any Paying Agent for, and to hold them harmless against, any loss,
liability or expense reasonably incurred without negligence or bad faith on their part arising out
of or in connection with actions taken or omitted by any of them in reliance on any Officer’s
Certificate furnished pursuant to this Section 10.4.

     Section 10.5. Limitation on Liens on Stock of Designated Subsidiaries.

     So long as any Securities are Outstanding, the Company will not, nor will it permit any
Subsidiary to, create, assume, incur, guarantee or otherwise permit to exist any Indebtedness
secured by any mortgage, pledge, lien, security interest or other encumbrance (a “Lien”) upon any
shares of Capital Stock of any Designated Subsidiary (whether such shares of stock are now owned or
hereafter acquired) without effectively providing concurrently that the Securities (and, if the
Company so elects, any other Indebtedness of the Company that is not subordinate to the Securities
and with respect to which the governing instruments require, or pursuant to which the Company is
otherwise obligated, to provide such security) shall be secured equally and ratably with such
Indebtedness for at least the time period such other Indebtedness is so secured.

     Section 10.6. Limitation on Disposition of Stock of Designated Subsidiaries.

     So long as any Securities are outstanding and except in a transaction otherwise governed by
this Indenture, the Company will not issue, sell, assign, transfer or otherwise dispose of any
shares of, securities convertible into, or warrants, rights or options to subscribe for or purchase
shares of, Capital Stock (other than Preferred Stock having no voting rights of any kind) of any
Designated Subsidiary, and will not permit any Designated Subsidiary to issue (other than to the
Company) any shares (other than the director’s qualifying shares) of, or securities convertible
into, or warrants, rights or options to subscribe for or purchase shares of, Capital Stock (other
than Preferred Stock having no voting rights of any kind) of any Designated Subsidiary, if, after
giving effect to any such transaction and the issuance of the maximum number of shares issuable
upon the conversion or exercise of all such convertible securities, warrants, rights or options,
the Company would own, directly or indirectly, less than 80% of the shares of Capital Stock of such
Designated Subsidiary (other than Preferred Stock having no voting rights of any kind); provided,
however, that (i) any issuance, sale, assignment, transfer or other disposition permitted by the
Company may only be made for at least a fair market value consideration as determined by the Board
of Directors pursuant to a Board Resolution adopted in good faith and (ii) the foregoing shall not
prohibit any such issuance or disposition of securities if required by any law or any regulation or
order of any governmental or insurance regulatory authority. Notwithstanding the foregoing, (i) the
Company may merge or consolidate any Designated Subsidiary into or with another direct or indirect
Subsidiary of the Company the shares of Capital Stock of which the Company owns at least 80% and
(ii) the Company may, subject to the provisions of Article 8, sell, assign, transfer or otherwise
dispose of the entire Capital Stock of any Designated Subsidiary at one time for at least a fair
market value consideration as determined by the Board of Directors pursuant to a Board Resolution
adopted in good faith.

65

 

     Section 10.7. Corporate Existence.

     Subject to Article 8, the Company shall do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence and that of each of its
Subsidiaries and their respective rights (charter and statutory) and franchises; provided, however,
that the foregoing shall not obligate the Company or any of its Subsidiaries to preserve any such
right or franchise if the Company or any such Subsidiary shall determine that the preservation
thereof is no longer desirable in the conduct of its business or the business of such Subsidiary
and that the loss thereof is not disadvantageous in any material respect to any Holder.

     Section 10.8. Waiver of Certain Covenants.

     The Company may omit in any particular instance to comply with any term, provision or
condition set forth in Sections 10.5, 10.6 or 10.7 with respect to the
Securities of any series if before the time for such compliance the Holders of at least a majority
in principal amount of the Outstanding Securities of such series, by Act of such Holders, either
shall waive such compliance in such instance or generally shall have waived compliance with such
term, provision or condition, but no such waiver shall extend to or affect such term, provision or
condition except to the extent so expressly waived, and, until such waiver shall become effective,
the obligations of the Company and the duties of the Trustee in respect of any such term, provision
or condition shall remain in full force and effect.

     Section 10.9. Company Statement as to Compliance; Notice of Certain Defaults.

     (1) The Company shall deliver to the Trustee, within 120 days after the end of each fiscal
year, a written statement (which need not be contained in or accompanied by an Officer’s
Certificate) signed by the principal executive officer, the principal financial officer or the
principal accounting officer of the Company, stating that

     (a) a review of the activities of the Company during such year and of its performance
under this Indenture has been made under his or her supervision, and

     (b) to the best of his or her knowledge, based on such review, (a) the Company has
complied with all the conditions and covenants imposed on it under this Indenture throughout
such year, or, if there has been a default in the fulfillment of any such condition or
covenant, specifying each such default known to him or her and the nature and status
thereof, and (b) no event has occurred and is continuing which is, or after notice or lapse
of time or both would become, an Event of Default, or, if such an event has occurred and is
continuing, specifying each such event known to him and the nature and status thereof.

     (2) The Company shall deliver to the Trustee, within five days after the occurrence thereof,
written notice of any Event of Default or any event which after notice or lapse of time or both
would become an Event of Default pursuant to clause (4) of Section 5.1.

     (3) The Trustee shall have no duty to monitor the Company’s compliance with the covenants
contained in this Article 10 other than as specifically set forth in this Section 10.9.

66

 

ARTICLE 11

Redemption of Securities

     Section 11.1. Applicability of Article.

     Redemption of Securities of any series at the option of the Company as permitted or required
by the terms of such Securities shall be made in accordance with the terms of such Securities and
(except as otherwise provided herein or pursuant hereto) this Article.

     Section 11.2. Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by or pursuant to a
Board Resolution. In case of any redemption at the election of the Company of (a) less than all of
the Securities of any series or (b) all of the Securities of any series, with the same issue date,
interest rate or formula, Stated Maturity and other terms, the Company shall, at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to
the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities
of such series to be redeemed.

     Section 11.3. Selection by Trustee of Securities to be Redeemed.

     If less than all of the Securities of any series with the same issue date, interest rate or
formula, Stated Maturity and other terms are to be redeemed, the particular Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee from
the Outstanding Securities of such series not previously called for redemption, by such method as
the Trustee shall deem fair and appropriate and which may provide for the selection for redemption
of portions of the principal amount of Registered Securities of such series; provided, however,
that no such partial redemption shall reduce the portion of the principal amount of a Registered
Security of such series not redeemed to less than the minimum denomination for a Security of such
series established herein or pursuant hereto.

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

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

     Unless otherwise specified in or pursuant to this Indenture or the Securities of any series,
if any Security selected for partial redemption is converted into Common Stock of the Company or
exchanged for other securities in part before termination of the conversion or exchange right with
respect to the portion of the Security so selected, the converted portion of such Security shall be
deemed (so far as may be) to be the portion selected for redemption. Securities which have been
converted or exchanged during a selection of Securities to be redeemed shall be treated by the
Trustee as Outstanding for the purpose of such selection.

67

 

     Section 11.4. Notice of Redemption.

     Notice of redemption shall be given in the manner provided in Section 1.6, not less
than 30 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in
the Securities to be redeemed, to the Holders of Securities to be redeemed. Failure to give notice
by mailing in the manner herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect
the validity of the proceedings for the redemption of any other Securities or portion thereof.

     Any notice that is mailed to the Holder of any Registered Securities in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not such Holder
receives the notice.

     All notices of redemption shall state:

     (1) the Redemption Date,

     (2) the Redemption Price,

     (3) if less than all Outstanding Securities of any series are to be redeemed, the
identification (and, in the case of partial redemption, the principal amount) of the particular
Security or Securities to be redeemed,

     (4) in case any Security is to be redeemed in part only, the notice which relates to such
Security shall state that on and after the Redemption Date, upon surrender of such Security, the
Holder of such Security will receive, without charge, a new Security or Securities of authorized
denominations for the principal amount thereof remaining unredeemed,

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

     (6) the place or places where such Securities, together (in the case of Bearer Securities)
with all Coupons appertaining thereto, if any, maturing after the Redemption Date, are to be
surrendered for payment of the Redemption Price and any accrued interest and Additional Amounts
pertaining thereto,

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

     (8) that, unless otherwise specified in such notice, Bearer Securities of any series, if any,
surrendered for redemption must be accompanied by all Coupons maturing subsequent to the date fixed
for redemption or the amount of any such missing Coupon or Coupons will be deducted from the
Redemption Price, unless security or indemnity satisfactory to the Company, the Trustee and any
Paying Agent is furnished,

     (9) if Bearer Securities of any series are to be redeemed and no Registered Securities of such
series are to be redeemed, and if such Bearer Securities may be exchanged for Registered

68

 

Securities not subject to redemption on the Redemption Date pursuant to Section 3.5 or
otherwise, the last date, as determined by the Company, on which such exchanges may be made,

     (10) in the case of Securities of any series that are convertible into Common Stock of the
Company or exchangeable for other securities, the conversion or exchange price or rate, the date or
dates on which the right to convert or exchange the principal of the Securities of such series to
be redeemed will commence or terminate and the place or places where such Securities may be
surrendered for conversion or exchange, and

     (11) the CUSIP number or the Euroclear or the Clearstream reference numbers of such
Securities, if any (or any other numbers used by a Depository to identify such Securities).

     A notice of redemption published as contemplated by Section 1.6 need not identify
particular Registered Securities to be redeemed.

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

     Section 11.5. Deposit of Redemption Price.

     On or prior to any Redemption Date, the Company shall deposit, with respect to the Securities
of any series called for redemption pursuant to Section 11.4, with the Trustee or with a
Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 10.3) an amount of money in the applicable Currency sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date,
unless otherwise specified pursuant to Section 3.1 or in the Securities of such series) any
accrued interest on and Additional Amounts with respect thereto, all such Securities or portions
thereof which are to be redeemed on that date.

     Section 11.6. Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall,
on the Redemption Date, become due and payable at the Redemption Price therein specified, and from
and after such date (unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest and the Coupons for such interest
appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall
be void. Upon surrender of any such Security for redemption in accordance with said notice,
together with all Coupons, if any, appertaining thereto maturing after the Redemption Date, such
Security shall be paid by the Company at the Redemption Price, together with any accrued interest
and Additional Amounts to the Redemption Date; provided, however, that, except as otherwise
provided in or pursuant to this Indenture or the Bearer Securities of such series, installments of
interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only upon presentation and surrender of Coupons for such interest (at an Office or Agency
located outside the United States except as otherwise provided in Section 10.2), and
provided, further, that, except as otherwise specified in or pursuant to this Indenture or the
Registered Securities of such series, installments of interest on Registered Securities whose
Stated Maturity is on or prior to the Redemption Date shall be

69

 

payable to the Holders of such Securities, or one or more Predecessor Securities, registered
as such at the close of business on the Regular Record Dates therefor according to their terms and
the provisions of Section 3.7.

     If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant
Coupons maturing after the Redemption Date, such Security may be paid after deducting from the
Redemption Price an amount equal to the face amount of all such missing Coupons, or the surrender
of such missing Coupon or Coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or
any Paying Agent any such missing Coupon in respect of which a deduction shall have been made from
the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided,
however, that any interest or Additional Amounts represented by Coupons shall be payable only upon
presentation and surrender of those Coupons at an Office or Agency for such Security located
outside of the United States except as otherwise provided in Section 10.2.

     If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal and any premium, until paid, shall bear interest from the Redemption Date
at the rate prescribed therefor in the Security.

     Section 11.7. Securities Redeemed in Part.

     Any Registered Security which is to be redeemed only in part shall be surrendered at any
Office or Agency for such Security (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing) and the
Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security
without service charge, a new Registered Security or Securities of the same series, containing
identical terms and provisions, of any authorized denomination as requested by such Holder in
aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered. If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depository or other Depository
for such Security in global form as shall be specified in the Company Order with respect thereto to
the Trustee, without service charge, a new Security in global form in a denomination equal to and
in exchange for the unredeemed portion of the principal of the Security in global form so
surrendered.

ARTICLE 12

Sinking Funds

     Section 12.1. Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for the retirement of
Securities of a series, except as otherwise permitted or required in or pursuant to this Indenture
or any Security of such series issued pursuant to this Indenture.

70

 

     The minimum amount of any sinking fund payment provided for by the terms of 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 Securities of such series is herein referred to as
an “optional sinking fund payment”. If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided in Section
12.2. Each sinking fund payment shall be applied to the redemption of Securities of any series
as provided for by the terms of Securities of such series and this Indenture.

     Section 12.2. Satisfaction of Sinking Fund Payments with Securities.

     The Company may, in satisfaction of all or any part of any sinking fund payment with respect
to the Securities of any series to be made pursuant to the terms of such Securities (1) deliver
Outstanding Securities of such series (other than any of such Securities previously called for
redemption or any of such Securities in respect of which cash shall have been released to the
Company), together in the case of any Bearer Securities of such series with all unmatured Coupons
appertaining thereto, and (2) apply as a credit Securities of such series which have been redeemed
either at the election of the Company pursuant to the terms of such series of Securities or through
the application of permitted optional sinking fund payments pursuant to the terms of such
Securities, provided that such series of Securities have not been previously so credited. Such
Securities shall be received and credited for such purpose by the Trustee at the Redemption Price
specified in such Securities for redemption through operation of the sinking fund and the amount of
such sinking fund payment shall be reduced accordingly. If, as a result of the delivery or credit
of Securities of any series in lieu of cash payments pursuant to this Section 12.2, the
principal amount of Securities of such series to be redeemed in order to satisfy the remaining
sinking fund payment shall be less than $100,000, the Trustee need not call Securities of such
series for redemption, except upon Company Request, and such cash payment shall be held by the
Trustee or a Paying Agent and applied to the next succeeding sinking fund payment, provided,
however, that the Trustee or such Paying Agent shall at the request of the Company from time to
time pay over and deliver to the Company any cash payment so being held by the Trustee or such
Paying Agent upon delivery by the Company to the Trustee of Securities of that series purchased by
the Company having an unpaid principal amount equal to the cash payment requested to be released to
the Company.

     Section 12.3. Redemption of Securities for Sinking Fund.

     Not less than 75 days prior to each sinking fund payment date for any series of Securities,
the Company shall deliver to the Trustee an Officer’s Certificate specifying the amount of the next
ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the
portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting of Securities of that series pursuant to
Section 12.2, and the optional amount, if any, to be added in cash to the next ensuing
mandatory sinking fund payment, and will also deliver to the Trustee any Securities to be so
credited and not theretofore delivered. If such Officer’s Certificate shall specify an optional
amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall
thereupon be obligated to pay the amount therein specified. Not less than 60 days before each such
sinking fund payment date the Trustee shall select the Securities to be redeemed upon such

71

 

sinking fund payment date in the manner specified in Section 11.3 and cause notice of
the redemption thereof to be given in the name of and at the expense of the Company in the manner
provided in Section 11.4. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections 11.6 and
11.7.

ARTICLE 13

Repayment at the Option of Holders

     Section 13.1. Applicability of Article.

     Securities of any series which are repayable at the option of the Holders thereof before their
Stated Maturity shall be repaid in accordance with the terms of the Securities of such series. The
repayment of any principal amount of Securities pursuant to such option of the Holder to require
repayment of Securities before their Stated Maturity, for purposes of Section 3.9, shall
not operate as a payment, redemption or satisfaction of the Indebtedness represented by such
Securities unless and until the Company, at its option, shall deliver or surrender the same to the
Trustee with a directive that such Securities be cancelled. Notwithstanding anything to the
contrary contained in this Section 13.1, in connection with any repayment of Securities,
the Company may arrange for the purchase of any Securities by an agreement with one or more
investment bankers or other purchasers to purchase such Securities by paying to the Holders of such
Securities on or before the close of business on the repayment date an amount not less than the
repayment price payable by the Company on repayment of such Securities, and the obligation of the
Company to pay the repayment price of such Securities shall be satisfied and discharged to the
extent such payment is so paid by such purchasers.

ARTICLE 14

Securities in Foreign Currencies

     Section 14.1. Applicability of Article.

     Whenever this Indenture provides for (i) any action by, or the determination of any of the
rights of, Holders of Securities of any series in which not all of such Securities are denominated
in the same Currency, or (ii) any distribution to Holders of Securities, in the absence of any
provision to the contrary in the form of Security of any particular series or pursuant to this
Indenture or the Securities, any amount in respect of any Security denominated in a Currency other
than Dollars shall be treated for any such action or distribution as that amount of Dollars that
could be obtained for such amount on such reasonable basis of exchange and as of the record date
with respect to Registered Securities of such series (if any) for such action, determination of
rights or distribution (or, if there shall be no applicable record date, such other date reasonably
proximate to the date of such action, determination of rights or distribution) as the Company may
specify in a written notice to the Trustee.

ARTICLE 15

Meetings of Holders of Securities

     Section 15.1. Purposes for Which Meetings May Be Called.

A meeting of Holders of Securities of any series may be called at any time and from time to time

72

Holders of Securities of such series.

     Section 15.2. Call, Notice and Place of Meetings.

     (1) The Trustee may at any time call a meeting of Holders of Securities of any series for any
purpose specified in Section 15.1, to be held at such time and at such place in the Borough
of Manhattan, The City of New York, or, if Securities of such series have been issued in whole or
in part as Bearer Securities, in London or in such place outside the United States as the Trustee
shall determine. Notice of every meeting of Holders of Securities of any series, setting forth the
time and the place of such meeting and in general terms the action proposed to be taken at such
meeting, shall be given, in the manner provided in Section 1.6, not less than 21 nor more
than 180 days prior to the date fixed for the meeting.

     (2) In case at any time the Company (by or pursuant to a Board Resolution) or the Holders of
at least 10% in principal amount of the Outstanding Securities of any series shall have requested
the Trustee to call a meeting of the Holders of Securities of such series for any purpose specified
in Section 15.1, by written request setting forth in reasonable detail the action proposed
to be taken at the meeting, and the Trustee shall not have mailed notice of or made the first
publication of the notice of such meeting within 21 days after receipt of such request (whichever
shall be required pursuant to Section 1.6) or shall not thereafter proceed to cause the
meeting to be held as provided herein, then the Company or the Holders of Securities of such
series in the amount above specified, as the case may be, may determine the time and the place in
the Borough of Manhattan, The City of New York, or, if Securities of such series are to be issued
as Bearer Securities, in London for such meeting and may call such meeting for such purposes by
giving notice thereof as provided in clause (1) of this Section 15.2.

     Section 15.3. Persons Entitled to Vote at Meetings.

     To be entitled to vote at any meeting of Holders of Securities of any series, a Person shall
be (1) a Holder of one or more Outstanding Securities of such series, or (2) a Person appointed by
an instrument in writing as proxy for a Holder or Holders of one or more Outstanding Securities of
such series by such Holder or Holders. The only Persons who shall be entitled to be present or to
speak at any meeting of Holders of Securities of any series shall be the Persons entitled to vote
at such meeting and their counsel, any representatives of the Trustee and its counsel and any
representatives of the Company and its counsel.

     Section 15.4. Quorum; Action.

     The Persons entitled to vote a majority in principal amount of the Outstanding Securities of a
series shall constitute a quorum for any meeting of Holders of Securities of such series. In the
absence of a quorum within 30 minutes after the time appointed for any such meeting, the meeting
shall, if convened at the request of Holders of Securities of such series, be dissolved. In any
other case the meeting may be adjourned for a period of not less than 10 days as determined by the
chairman of the meeting prior to the adjournment of such meeting. In the absence of a quorum at any
reconvened meeting, such reconvened meeting may be further adjourned for a

73

 

period of not less than 10 days as determined by the chairman of the meeting prior to the
adjournment of such reconvened meeting. Notice of the reconvening of any adjourned meeting shall be
given as provided in Section 15.2(1), except that such notice need be given only once not
less than five days prior to the date on which the meeting is scheduled to be reconvened. Notice of
the reconvening of an adjourned meeting shall state expressly the percentage, as provided above, of
the principal amount of the Outstanding Securities of such series which shall constitute a quorum.

     Except as limited by the proviso to Section 9.2, any resolution presented to a meeting
or adjourned meeting duly reconvened at which a quorum is present as aforesaid may be adopted only
by the affirmative vote of the Holders of a majority in principal amount of the Outstanding
Securities of that series; provided, however, that, except as limited by the proviso to Section
9.2, any resolution with respect to any request, demand, authorization, direction, notice,
consent, waiver or other Act which this Indenture expressly provides may be made, given or taken by
the Holders of a specified percentage, which is less than a majority, in principal amount of the
Outstanding Securities of a series may be adopted at a meeting or an adjourned meeting duly
reconvened and at which a quorum is present as aforesaid by the affirmative vote of the Holders of
such specified percentage in principal amount of the Outstanding Securities of such series.

     Any resolution passed or decision taken at any meeting of Holders of Securities of any series
duly held in accordance with this Section 15.4 shall be binding on all the Holders of
Securities of such series and the Coupons appertaining thereto, whether or not such Holders were
present or represented at the meeting.

     Section 15.5. Determination of Voting Rights; Conduct and Adjournment of Meetings.

     (1) Notwithstanding any other provisions of this Indenture, the Trustee may make such
reasonable regulations as it may deem advisable for any meeting of Holders of Securities of such
series in regard to proof of the holding of Securities of such series and of the appointment of
proxies and in regard to the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise
permitted or required by any such regulations, the holding of Securities shall be proved in the
manner specified in Section 1.4 and the appointment of any proxy shall be proved in the
manner specified in Section 1.4 or by having the signature of the person executing the
proxy witnessed or guaranteed by any trust company, bank or banker authorized by Section
1.4 to certify to the holding of Bearer Securities. Such regulations may provide that written
instruments appointing proxies, regular on their face, may be presumed valid and genuine without
the proof specified in Section 1.4 or other proof.

     (2) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the
meeting, unless the meeting shall have been called by the Company or by Holders of Securities as
provided in Section 15.2(2), in which case the Company or the Holders of Securities of the
series calling the meeting, as the case may be, shall in like manner appoint a temporary chairman.
A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the
Persons entitled to vote a majority in principal amount of the Outstanding Securities of such
series represented at the meeting.

74

 

     (3) At any meeting, each Holder of a Security of such series or proxy shall be entitled to one
vote for each $1,000 principal amount of Securities of such series held or represented by him;
provided, however, that no vote shall be cast or counted at any meeting in respect of any Security
challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The
chairman of the meeting shall have no right to vote, except as a Holder of a Security of such
series or proxy.

     (4) Any meeting of Holders of Securities of any series duly called pursuant to Section
15.2 at which a quorum is present may be adjourned from time to time by Persons entitled to
vote a majority in principal amount of the Outstanding Securities of such series represented at the
meeting; and the meeting may be held as so adjourned without further notice.

     Section 15.6. Counting Votes and Recording Action of Meetings.

     The vote upon any resolution submitted to any meeting of Holders of Securities of any series
shall be by written ballots on which shall be subscribed the signatures of the Holders of
Securities of such series or of their representatives by proxy and the principal amounts and serial
numbers of the Outstanding Securities of such series held or represented by them. The permanent
chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the
meeting for or against any resolution and who shall make and file with the secretary of the meeting
their verified written reports in triplicate of all votes cast at the meeting. A record, at least
in triplicate, of the proceedings of each meeting of Holders of Securities of any series shall be
prepared by the secretary of the meeting and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or
more persons having knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 15.2 and, if applicable,
Section 15.4. Each copy shall be signed and verified by the affidavits of the permanent
chairman and secretary of the meeting and one such copy shall be delivered to the Company, and
another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the
ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

Exhibit 4.1

BMP SUNSTONE CORPORATION

WARRANT TO PURCHASE COMMON STOCK

			
	 	 	 
	WARRANT NO.
	 	ORIGINAL ISSUE DATE: FEBRUARY 20, 2009

     BMP Sunstone Corporation, a Delaware corporation (the “Company”), hereby certifies that, for
value received, [                    ] or its permitted registered assigns (the “Holder”), is entitled to
purchase from the Company up to a total of [                    ] shares of common stock, $0.001 par value per
share (the “Common Stock”), of the Company (each such share, a “Warrant Share” and all such shares,
the “Warrant Shares”) at an exercise price equal to $4.00 per share (as adjusted from time to time
as provided herein, the “Exercise Price”), at any time and from time to time on or after May 21,
2009 (the “Original Exercisability Date”) and through and including February 20, 2014 (the
“Expiration Date”), and subject to the following terms and conditions:

     This Warrant is being issued pursuant to that certain Purchase Agreement, dated February 13,
2009, by and between the Company and the Holder (the “Purchase Agreement”). The original issuance
of the Warrant by the Company pursuant to the Purchase Agreement has been registered pursuant to a
Registration Statement on Form S-3 (File No. 333-156958) (the “Registration Statement”).

     1. Definitions. In addition to the terms defined elsewhere in this
Warrant, capitalized terms that are not otherwise defined herein have the meanings given to such
terms in the Purchase Agreement.

     2. List of Warrant Holders. The Company shall register this Warrant, upon
records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of
the Holder (which shall include the Holder and, as the case may be, any registered assignee to
which this Warrant is permissibly assigned hereunder from time to time). The Company may deem and
treat the Holder of this Warrant as the absolute owner hereof for the purpose of any exercise
hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the
contrary.

     3. List of Transfers; Restrictions on Transfer. The Company shall register
any transfer of all or any portion of this Warrant in the Warrant Register, upon surrender of this
Warrant, with the Form of Assignment attached hereto duly completed and signed, to the Company at
its address specified herein. Upon any transfer, a new warrant to purchase Common Stock, in
substantially the form of this Warrant (any such new warrant, a “New Warrant”), evidencing the
portion of this Warrant so transferred shall be issued to the transferee and a New Warrant
evidencing the remaining portion of this Warrant not so transferred, if any, shall be

 

 

issued to the transferring Holder. The acceptance of the New Warrant by the transferee thereof
shall be deemed the acceptance by such transferee of all of the rights and obligations in respect
of the New Warrant that the Holder has in respect of this Warrant.

     4. Exercise and Duration of Warrant.

          (a) All or any part of this Warrant shall be exercisable by the Holder in any manner
permitted by Section 10 of this Warrant at any time and from time to time on or after the Original
Exercisability Date and through and including the Expiration Date. Subject to Section 11 hereof, at
5:00 p.m., New York City time, on the Expiration Date, the portion of this Warrant not exercised
prior thereto shall be and become void and of no value and this Warrant shall be terminated and no
longer outstanding.

          (b) The Holder may exercise this Warrant by delivering to the Company (i) an
exercise notice, in the form attached hereto (the “Exercise Notice”), completed and duly signed,
and (ii) if such Holder is not utilizing the cashless exercise provisions set forth in this
Warrant, payment of the Exercise Price for the number of Warrant Shares as to which this Warrant is
being exercised. The date such items are delivered to the Company (as determined in accordance
with the notice provisions hereof) is an “Exercise Date.” The Holder shall not be required to
deliver the original Warrant in order to effect an exercise hereunder, but if it is not so
delivered then such exercise shall constitute an agreement by the Holder to deliver the original
Warrant to the Company as soon as practicable thereafter. Execution and delivery of the Exercise
Notice shall have the same effect as cancellation of the original Warrant and issuance of a New
Warrant evidencing the right to purchase the remaining number of Warrant Shares.

     5. Delivery of Warrant Shares.

          (a) Upon exercise of this Warrant, the Company shall promptly (but in no event later
than three Trading Days (as defined below) after the Exercise Date) issue or cause to be issued and
cause to be delivered to or upon the written order of the Holder and in such name or names as the
Holder may designate, a certificate for the Warrant Shares issuable upon such exercise, free of
restrictive legends. The Holder, or any Person permissibly so designated by the Holder to receive
Warrant Shares, shall be deemed to have become the holder of record of such Warrant Shares as of
the Exercise Date. The Company shall, upon the written request of the Holder, use its best efforts
to deliver, or cause to be delivered, Warrant Shares hereunder electronically through the
Depository Trust and Clearing Corporation or another established clearing corporation performing
similar functions, if available; provided, that, the Company may, but will not be required to,
change its transfer agent if its current transfer agent cannot deliver Warrant Shares
electronically through the Depository Trust and Clearing Corporation. If, as of the time of
exercise the Warrant Shares constitute restricted or control securities, the Holder, by exercising,
agrees not to resell them except in compliance with all applicable securities laws.

          “Trading Day” means any day other than a Saturday or a Sunday on which the Principal Market is
open for trading in equity securities. “Principal Market” means the NASDAQ

 

 

Capital Market, the NASDAQ Global Select Market, the NASDAQ Global Market, the American Stock
Exchange or the New York Stock Exchange, whichever is at the time the principal trading exchange or
market for the Common Stock.

          (b) If by the close of the third Trading Day after delivery of an Exercise Notice
and the payment of the aggregate exercise price in any manner permitted by Section 10 of this
Warrant, the Company fails to deliver to the Holder a certificate representing the required number
of Warrant Shares in the manner required pursuant to Section 5(a), and if after such third Trading
Day and prior to the receipt of such Warrant Shares, the Holder purchases (in an open market
transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder
of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then
the Company shall, within three Trading Days after the Holder’s request and in the Holder’s sole
discretion, either (i) pay in cash to the Holder an amount equal to the Holder’s total purchase
price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the
“Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue
such Warrant Shares) shall terminate or (ii) promptly honor its obligation to deliver to the Holder
a certificate or certificates representing such Warrant Shares and pay cash to the Holder in an
amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of
Warrant Shares, times (B) the closing bid price on the date of the event giving rise to the
Company’s obligation to deliver such certificate.

          (c) To the extent permitted by law, the Company’s obligations to issue and deliver
Warrant Shares in accordance with the terms hereof are absolute and unconditional, irrespective of
any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any
provision hereof, the recovery of any judgment against any Person or any action to enforce the
same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged
breach by the Holder or any other Person of any obligation to the Company or any violation or
alleged violation of law by the Holder or any other Person, and irrespective of any other
circumstance that might otherwise limit such obligation of the Company to the Holder in connection
with the issuance of Warrant Shares. Nothing herein shall limit Holder’s right to pursue any other
remedies available to it hereunder, at law or in equity including, without limitation, a decree of
specific performance and/or injunctive relief with respect to the Company’s failure to timely
deliver certificates representing shares of Common Stock upon exercise of the Warrant as required
pursuant to the terms hereof.

     6. Charges, Taxes and Expenses. Issuance and delivery of certificates for
shares of Common Stock upon exercise of this Warrant shall be made without charge to the Holder for
any issue or transfer tax, withholding tax, transfer agent fee or other incidental tax or expense
in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by
the Company; provided, however, that the Company shall not be required to pay any tax that may be
payable in respect of any transfer involved in the registration of any certificates for Warrant
Shares or the Warrants in a name other than that of the Holder. The Holder shall be responsible for
all other tax liability that may arise as a result of holding or transferring this Warrant or
receiving Warrant Shares upon exercise hereof.

 

 

     7. Replacement of Warrant. If this Warrant is mutilated, lost, stolen or
destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon
cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon
receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and
customary and reasonable indemnity, if requested. Applicants for a New Warrant under such
circumstances shall also comply with such other reasonable regulations and procedures and pay such
other reasonable third-party costs as the Company may prescribe. If a New Warrant is requested as a
result of a mutilation of this Warrant, then the Holder shall deliver such mutilated Warrant to the
Company as a condition precedent to the Company’s obligation to issue the New Warrant.

     8. Reservation of Warrant Shares. The Company covenants that it will at
all times reserve and keep available out of the aggregate of its authorized but unissued and
otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares
upon exercise of this Warrant as herein provided, the number of Warrant Shares that are then
issuable and deliverable upon the exercise of this entire Warrant, free from preemptive rights or
any other contingent purchase rights of Persons other than the Holder (taking into account the
adjustments and restrictions of Section 9). The Company covenants that all Warrant Shares so
issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in
accordance with the terms hereof, be duly and validly authorized, issued and fully paid and
nonassessable.

     9. Certain Adjustments. The Exercise Price and number of Warrant Shares
issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in
this Section 9.

          (a) On the 90th day from the date hereof, if the VWAP (as defined below) for the 20
Trading Days preceding such date, is less than $4.00, the Exercise Price shall be adjusted to the
greater of (i) the VWAP for the 20 Trading Days preceding such date, or (ii) $1.80. However,
notwithstanding the foregoing, in no event shall the aggregate number of shares of Common Stock and
the aggregate number of shares underlying the warrants issued pursuant to the Purchase Agreements
dated February 13, 2009 between the Company and the purchasers therein exceed 19.99% of the Common
Stock outstanding as of February 13, 2009.

     “VWAP” means the volume weighted average price (the aggregate sales price of all trades of
Common Stock during each Trading Day divided by the total number of shares of Common Stock traded
during such Trading Day) of the Common Stock during any Trading Day as reported by Bloomberg, L.P.
using the AQR function.

          (b) Stock Dividends and Splits. If the Company, at any time while this
Warrant is outstanding, (i) pays a stock dividend on its Common Stock or otherwise makes a
distribution on any class of capital stock that is payable in shares of Common Stock, (ii)
subdivides outstanding shares of Common Stock into a larger number of shares, or (iii) combines
outstanding shares of Common Stock into a smaller number of shares, then in each such case the

 

 

Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding immediately before such event and of which the denominator shall
be the number of shares of Common Stock outstanding immediately after such event. Any adjustment
made pursuant to clause (i) of this paragraph shall become effective immediately after the record
date for the determination of stockholders entitled to receive such dividend or distribution, and
any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective
immediately after the effective date of such subdivision or combination.

          (c) Pro Rata Distributions. If the Company, at any time while this Warrant
is outstanding, distributes to all holders of Common Stock for no consideration (i) evidences of
its indebtedness, (ii) any security (other than a distribution of Common Stock covered by the
preceding paragraph), (iii) rights or warrants to subscribe for or purchase any security, or (iv)
any other asset besides cash (in each case, “Distributed Property”), then, upon any exercise of
this Warrant that occurs after the record date fixed for determination of stockholders entitled to
receive such distribution, the Holder shall be entitled to receive, in addition to the Warrant
Shares otherwise issuable upon such exercise (if applicable), the Distributed Property that such
Holder would have been entitled to receive in respect of such number of Warrant Shares had the
Holder been the record holder of such Warrant Shares immediately prior to such record date.

          (d) Fundamental Transactions. If, at any time while this Warrant is
outstanding (i) the Company effects (A) any merger of the Company with (but not into) another
entity, in which the shareholders of the Company immediately prior to the transaction own less than
a majority of the outstanding stock of the surviving entity, or (B) any merger or consolidation of
the Company into another entity, (ii) the Company effects any sale of all or substantially all of
its assets in one or a series of related transactions, (iii) any tender offer or exchange offer
approved or authorized by the Company’s Board of Directors is completed pursuant to which holders
of at least a majority of the outstanding Common Stock tender or exchange their shares for other
securities, cash or property, or (iv) the Company effects any reclassification of the Common Stock
or any compulsory share exchange pursuant to which the Common Stock is effectively converted into
or exchanged for other securities, cash or property (each, a “Fundamental Transaction”), then the
Holder shall have the right thereafter to receive, upon exercise of this Warrant, the same amount
and kind of securities, cash or property as it would have been entitled to receive upon the
occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental
Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full of this
Warrant without regard to any limitations on exercise contained herein (the “Alternate
Consideration”), and the Holder shall no longer have the right to receive Warrant Shares upon
exercise of this Warrant. The Company shall not effect any such Fundamental Transaction unless
prior to or simultaneously with the consummation thereof, any successor to the Company, surviving
entity or the corporation purchasing or otherwise acquiring such assets or other appropriate
corporation or entity shall assume the obligation to deliver to the Holder, such Alternate
Consideration as, in accordance with the foregoing provisions, the Holder may be entitled to
receive, and the other obligations under this Warrant. The provisions of this paragraph (c) shall
similarly apply to subsequent transactions of a Fundamental Transaction type.

 

 

          (e) Number of Warrant Shares. Simultaneously with any adjustment to the
Exercise Price pursuant to paragraph (b) of this Section 9, the number of Warrant Shares that may
be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that
after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of
Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to
such adjustment.

          (f) Calculations. All calculations under this Section 9 shall be made to
the nearest cent or the nearest 1/100th of a share, as applicable. The number of shares of Common
Stock outstanding at any given time shall not include shares owned or held by or for the account of
the Company, and the disposition of any such shares shall be considered an issue or sale of Common
Stock.

          (g) Notice of Adjustments. Upon the occurrence of each adjustment pursuant
to this Section 9, the Company at its expense will, at the written request of the Holder, promptly
compute such adjustment in accordance with the terms of this Warrant and prepare a certificate
setting forth such adjustment, in good faith, including a statement of the adjusted Exercise Price
and adjusted number or type of Warrant Shares or other securities issuable upon exercise of this
Warrant (as applicable), describing the transactions giving rise to such adjustments and showing in
detail the facts upon which such adjustment is based. Upon written request, the Company will
promptly deliver a copy of each such certificate to the Holder and to the Company’s Transfer Agent.

          (h) Notice of Corporate Events. If, while this Warrant is outstanding, the
Company (i) declares a dividend or any other distribution of cash, securities or other property in
respect of its Common Stock, including without limitation any granting of rights or warrants to
subscribe for or purchase any capital stock of the Company or any subsidiary, (ii) authorizes or
approves, enters into any agreement contemplating or solicits stockholder approval for any
Fundamental Transaction or (iii) authorizes the voluntary dissolution, liquidation or winding up of
the affairs of the Company, then, except if such notice and the contents thereof shall be deemed to
constitute material non-public information, the Company shall deliver to the Holder a notice
describing the material terms and conditions of such transaction at least 10 Trading Days prior to
the applicable record or effective date on which a Person would need to hold Common Stock in order
to participate in or vote with respect to such transaction, and the Company will take all
reasonable steps to give Holder the practical opportunity to exercise this Warrant prior to such
time; provided, however, that the failure to deliver such notice or any defect therein shall not
affect the validity of the corporate action required to be described in such notice.

     10. Payment of Exercise Price. The Holder may pay the Exercise Price in one
of the following manners:

          (a) Cash Exercise. If an Exercise Notice is delivered at a time when the
Registration Statement is effective, then the Holder shall deliver immediately available funds; or

 

 

          (b) Cashless Exercise. If an Exercise Notice is delivered at a time when the
Registration Statement is not then effective, then the Holder shall notify the Company in an
Exercise Notice of its election to utilize cashless exercise, in which event the Company shall
issue to the Holder the number of Warrant Shares determined as follows:

X = Y [(A-B)/A]

     where:

X = the number of Warrant Shares to be issued to the Holder.

Y = the number of Warrant Shares with respect to which this Warrant is being
exercised.

A = the closing price on the Trading Day immediately prior to the Exercise Date.

B = the Exercise Price then in effect.

     11. Limitations on Exercise.

          (a) Notwithstanding anything to the contrary contained herein, the number of Warrant
Shares that may be acquired by the Holder upon any exercise of this Warrant (or otherwise in
respect hereof) shall be limited to the extent necessary to ensure that, following such exercise
(or other issuance), the total number of shares of Common Stock then beneficially owned by the
Holder and its affiliates and any other Persons whose beneficial ownership of Common Stock would be
aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act, does not exceed
4.99% of the total number of issued and outstanding shares of Common Stock (including for such
purpose the shares of Common Stock issuable upon such exercise). For such purposes, beneficial
ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules
and regulations promulgated thereunder. Each delivery of an Exercise Notice by the Holder will
constitute a representation by the Holder that it has evaluated the limitation set forth in this
Section and determined that issuance of the full number of Warrant Shares requested in such
Exercise Notice is permitted under this Section. The Company’s obligation to issue shares of
Common Stock in excess of the limitation referred to in this Section shall be suspended (and,
except as provided below, shall not terminate or expire notwithstanding any contrary provisions
hereof) until such time, if any, as such shares of Common Stock may be issued in compliance with
such limitation; provided, that, if, as of 5:00 P.M., New York City time, on the Expiration Date,
the Company has not received written notice that the shares of Common Stock may be issued in
compliance with such limitation, the Company’s obligation to issue such shares shall terminate.
This provision shall not restrict the number of shares of Common Stock which a Holder may receive
or beneficially own in order to determine the amount of securities or other consideration that such
Holder may receive in the event of a Fundamental Transaction as contemplated in Section 9 of this
Warrant. By written notice to the Company, the Holder may waive the provisions of this Section but
any such waiver will not be effective until the 61st day after such notice is delivered to the
Company, nor will any such waiver affect any other Holder.

 

 

          (b) Notwithstanding anything to the contrary contained herein, the
number of Warrant Shares that may be acquired by the Holder upon any exercise of this Warrant (or
otherwise in respect hereof) shall be limited to the extent necessary to ensure that, following
such exercise (or other issuance), the total number of shares of Common Stock then beneficially
owned by such Holder and its affiliates and any other Persons whose beneficial ownership of Common
Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act, does
not exceed 9.99% of the total number of issued and outstanding shares of Common Stock (including
for such purpose the shares of Common Stock issuable upon such exercise). For such purposes,
beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and
the rules and regulations promulgated thereunder. Each delivery of an Exercise Notice hereunder
will constitute a representation by the Holder that it has evaluated the limitation set forth in
this Section and determined that issuance of the full number of Warrant Shares requested in such
Exercise Notice is permitted under this Section. The Company’s obligation to issue shares of
Common Stock in excess of the limitation referred to in this Section shall be suspended (and,
except as provided below, shall not terminate or expire notwithstanding any contrary provisions
hereof) until such time, if any, as such shares of Common Stock may be issued in compliance with
such limitation; provided, that, if, as of 5:00 P.M., New York City time, on the Expiration Date,
the Company has not received written notice that the shares of Common Stock may be issued in
compliance with such limitation, the Company’s obligation to issue such shares shall terminate.
This provision shall not restrict the number of shares of Common Stock which a Holder may receive
or beneficially own in order to determine the amount of securities or other consideration that such
Holder may receive in the event of a Fundamental Transaction as contemplated in Section 9 of this
Warrant. This restriction may not be waived.

     12. No Fractional Shares. No fractional Warrant Shares will be issued in
connection with any exercise of this Warrant. In lieu of any fractional shares that would otherwise
be issuable, the Company shall pay cash equal to the product of such fraction multiplied by the
closing price of one Warrant Share as reported by the Principal Market or other applicable trading
market on the Exercise Date.

     13. Notices. Any and all notices or other communications or deliveries
hereunder (including, without limitation, any Exercise Notice) shall be in writing and shall be
deemed given and effective on the earliest of (i) the date of transmission, if such notice or
communication is delivered via facsimile at the facsimile number specified in this Section at or
prior to 5:00 p.m. (New York City time) on a Trading Day, (ii) the next Trading Day after the date
of transmission, if such notice or communication is delivered via facsimile at the facsimile number
specified in this Section on a day that is not a Trading Day or later than 5:00 p.m. (New York City
time) on any Trading Day, (iii) the Trading Day following the date of mailing, if sent by
nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom
such notice is required to be given. The addresses for such notices or communications shall be: if
to the Company, to BMP Sunstone Corporation, 600 W. Germantown Pike, Suite 400, Plymouth Meeting,
Pennsylvania 19462, Attention: Chief Financial Officer (or such other address as the Company shall
indicate in writing in accordance with this Section) or (ii) if to the

 

 

Holder, to the address or facsimile number appearing on the Warrant Register (or such other address
as the Holder shall indicate in writing in accordance with this Section).

     14. Warrant Agent. The Company shall serve as warrant agent under this
Warrant. Upon 30 days’ notice to the Holder, the Company may appoint a new warrant agent. Any
corporation into which the Company or any new warrant agent may be merged or any corporation
resulting from any consolidation to which the Company or any new warrant agent shall be a party or
any corporation to which the Company or any new warrant agent transfers substantially all of its
corporate trust or shareholders services business shall be a successor warrant agent under this
Warrant without any further act. Any such successor warrant agent shall promptly cause notice of
its succession as warrant agent to be mailed (by first class mail, postage prepaid) to the Holder
at the Holder’s last address as shown on the Warrant Register.

     15. Miscellaneous.

          (a) This Warrant shall be binding on and inure to the benefit of the parties hereto
and their respective successors and assigns. Subject to the preceding sentence, nothing in this
Warrant shall be construed to give to any Person other than the Company and the Holder any legal or
equitable right, remedy or cause of action under this Warrant. This Warrant may be amended only in
writing signed by the Company and the Holder, or their successors and assigns.

          (b) All questions concerning the construction, validity, enforcement and
interpretation of this Warrant shall be governed by and construed and enforced in accordance with
the internal laws of the State of New York, without regard to the principles of conflicts of law
thereof that would result in the application of any other law. Each party irrevocably submits to
the jurisdiction of any court of the State of New York located in the City and County of New York
or in the United States District Court for the Southern District of New York for the purpose of any
suit, action or other proceeding arising out of this Agreement or our engagement hereunder. Each
party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any and
all right to trial by jury in any legal proceeding arising out of or relating to this Warrant or
the transactions contemplated hereby.

          (c) The headings herein are for convenience only, do not constitute a part of this
Warrant and shall not be deemed to limit or affect any of the provisions hereof.

          (d) In case any one or more of the provisions of this Warrant shall be invalid or
unenforceable in any respect, the validity and enforceability of the remaining terms and provisions
of this Warrant shall not in any way be affected or impaired thereby and the parties will attempt
in good faith to agree upon a valid and enforceable provision which shall be a commercially
reasonable substitute therefore, and upon so agreeing, shall incorporate such substitute provision
in this Warrant.

 

 

          (e) Prior to exercise of this Warrant, the Holder hereof shall not, by reason of by
being a Holder, be entitled to any rights of a stockholder with respect to the Warrant Shares.

 

 

     IN WITNESS WHEREOF, the Company has caused this Warrant to be duly executed by its authorized
officer as of the date first indicated above.
