ARTICLE 2

Issue, Description, Execution, Registration and Exchange of Notes

Section 2.01. Designation Amount and Issue of Notes. The Notes shall be designated as the “6.875%
Convertible Senior Notes due 2027.” Upon the execution of this Indenture, and from time to time
thereafter, Notes may be executed by the Issuer and delivered to the Trustee for authentication,
and the Trustee shall thereupon authenticate and deliver Notes upon a written order of the Issuer,
signed by an Officer, without any further action by the Issuer hereunder.

The aggregate principal amount of Notes which may be authenticated and delivered under this
Indenture is initially limited to $350,000,000 (or $425,000,000 if the Initial Purchaser’s option
set forth in the Purchase Agreement is exercised in full). The Issuer may, without the consent of
the holders of Notes, increase the aggregate principal amount of the Notes by issuing additional
Notes (the “Additional Notes”) from time to time in the future on the same terms and conditions,
except for any difference in the issue price and interest accrued prior to the issue date of the
Additional Notes, and with the same CUSIP number as the Notes originally issued under this
Indenture (the “Initial Notes”), provided that such Additional Notes constitute part of the same
issue as the Initial Notes for United States federal income tax purposes. The Initial Notes and
any such Additional Notes will rank equally and ratably and will be treated as a single series of
Notes for all purposes under this Indenture.

Section 2.02. Form of Notes. The Notes and the Trustee’s certificate of authentication to be borne
by such Notes shall be substantially in the form set forth in Exhibit A hereto. The terms
and provisions contained in the form of Note attached as Exhibit A hereto shall constitute,
and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Issuer
and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms
and provisions and to be bound thereby.

Any of the Notes may have such letters, numbers or other marks of identification and such
notations, legends, endorsements or changes as the officers executing the same may approve
(execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the
provisions of this Indenture, or as may be required by the Custodian, the Depositary or by the
National Association of Securities Dealers, Inc. in order for the Notes to be tradable on The
PORTAL Market or as may be required for the Notes to be tradable on any other market developed for
trading of securities pursuant to Rule 144A or as may be required to comply with any applicable law
or with any rule or regulation made pursuant thereto or with any rule or regulation of any
securities exchange or automated quotation system on which the Notes may be listed, or to conform
to usage, or to indicate any special limitations or restrictions to which any particular Notes are
subject.

So long as the Notes are eligible for book-entry settlement with the Depositary, or unless
otherwise required by law, or otherwise contemplated by Section 2.05(b), all of the Notes will be
represented by one or more Notes in global form registered in the name of the Depositary or the
nominee of the Depositary (a “Global Note”). The transfer and exchange of beneficial interests in
any such Global Note shall be effected through the Depositary in accordance with this Indenture and
the applicable procedures of the Depositary. Except as provided in Section 2.05(b), beneficial
owners of a Global Note shall not be entitled to have certificates registered in their names, will
not receive or be entitled to receive physical delivery of certificates in definitive form and will
not be considered holders of such Global Note.

Any Global Note shall represent such of the outstanding Notes as shall be specified therein
and shall provide that it shall represent the aggregate amount of outstanding Notes from time to
time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may
from time to time be increased or reduced to reflect redemptions, repurchases, conversions,
exchanges or transfers permitted hereby. Any endorsement of a Global Note to reflect the amount of
any increase or decrease in the amount of outstanding Notes represented thereby shall be made by
the Trustee or the Custodian, at the direction of the Trustee, in such manner and upon instructions
given by the holder of such Notes in accordance with this Indenture. Payment of principal of, and
interest on, any Global Note shall be made to the holder of such Note.

Section 2.03. Date and Denomination of Notes; Payments of Interest.The Notes shall be issuable in
registered form without coupons in denominations of $1,000 principal amount and integral multiples
thereof. Each Note shall be dated the date of its authentication and shall bear interest from the
date specified on the face of the form of Note attached as Exhibit A hereto. Interest on
the Notes shall be computed on the basis of a 360-day year consisting of twelve 30-day months.

The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register
at the close of business, New York City time, on any Record Date with respect to any Interest
Payment Date shall be entitled to receive the interest payable on such Interest Payment Date;
provided that interest payable on the Stated Maturity shall be payable to the Person to whom
principal is payable; and provided, further that if an Interest Payment Date falls on or prior to a
Redemption Date, a Change in Control Repurchase Date or an Optional Repurchase Date, as the case
may be, the semi-annual payment of interest becoming due on such Interest Payment Date shall be
payable to the holder of such Note registered as such on the related Record Date. Interest shall
be payable at the office of the Issuer maintained by the Issuer for such purposes, which shall
initially be an office or agency of the Trustee. The Issuer shall pay interest (i) on any Notes in
certificated form by check mailed to the address of the Person entitled thereto as it appears in
the Note Register; provided, however, that a holder of any Notes in certificated form in the
aggregate principal amount of more than $5.0 million may specify by written notice to the Issuer
that it pay interest by wire transfer of immediately available funds to the account specified by
the Noteholder in such notice, or (ii) on any Global Note by wire transfer of immediately available
funds to the account of the Depositary or its nominee. If a payment date is not a Business Day,
payment shall be made on the next succeeding Business Day, and no additional interest shall accrue
thereon. The term “Record Date” with respect to any Interest Payment Date shall mean the April 1
or the October 1, in each case whether or not such day is a Business Day, next preceding the
applicable Interest Payment Date. Interest payable on each Interest Payment Date or any other date
on which interest shall be payable shall equal the amount of interest accrued for the period from
and including the immediately preceding Interest Payment Date in respect of which interest has been
paid (or from and including April 18, 2007 if no interest shall have been payable) to but excluding
such Interest Payment Date or other date on which such interest should be payable.

Any interest on any Note which is payable, but is not punctually paid or duly provided for, on
any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable
to the Noteholder registered as such on the relevant Record Date, and such Defaulted Interest shall
be paid by the Issuer, at its election in each case, as provided in clause (1) or (2) below:

(1) The Issuer may elect to make payment of any Defaulted Interest to the Persons in whose
names the Notes (or their respective Predecessor Notes) are registered at the close of business,
New York City time, on a special record date for the payment of such Defaulted Interest, which
shall be fixed in the following manner. The Issuer shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment
(which shall be not less than twenty five (25) calendar days after the receipt by the Trustee of
such notice, unless the Trustee shall consent to an earlier date), and at the same time the Issuer
shall deposit with the Trustee an amount of money equal to the aggregate amount 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 deposited to be held in
trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause
provided. Thereupon the Trustee shall fix a special record date for the payment of such Defaulted
Interest which shall be not more than fifteen (15) calendar days and not less than ten (10)
calendar days prior to the date of the proposed payment, and not less than ten (10) calendar days
after the receipt by the Trustee of the notice of the proposed payment (unless the Trustee shall
consent to an earlier date). The Trustee shall promptly notify the Issuer of such special record
date and, in the name and at the expense of the Issuer, shall cause notice of the proposed payment
of such Defaulted Interest and the special record date therefor to be mailed, first-class postage
prepaid, to each holder at its address as it appears in the Note Register, not less than ten
calendar days prior to such special record date (unless, the Trustee shall consent to an earlier
date). Notice of the proposed payment of such Defaulted Interest and the special record date
therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names
the Notes (or their respective Predecessor Notes) are registered at the close of business, New York
City time, on such special record date and shall no longer be payable pursuant to the following
clause (2) of this Section 2.03.

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

Section 2.04. Execution of Notes. The Notes shall be signed in the name and on behalf of the
Issuer by the manual or facsimile signature of an Officer. Only such Notes as shall bear thereon a
certificate of authentication substantially in the form set forth on the form of Note attached as
Exhibit A hereto, manually executed by the Trustee (or an authenticating agent appointed by
the Trustee as provided by Section 15.11), shall be entitled to the benefits of this Indenture or
be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating
agent) upon any Note executed by the Issuer shall be conclusive evidence that the Note so
authenticated has been duly authenticated and delivered hereunder and that the holder is entitled
to the benefits of this Indenture.

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

Section 2.05. Exchange and Registration of Transfer of Notes; Restrictions on Transfer.

(a) The Issuer shall cause to be kept at the Corporate Trust Office a register (the register
maintained in such office and in any other office or agency of the Issuer designated pursuant to
Section 4 being herein sometimes collectively referred to as the “Note Register”) in which, subject
to such reasonable regulations as it may prescribe, the Issuer shall provide for the registration
of Notes and of transfers of Notes. The Note Register shall be in written form or in any form
capable of being exchanged into written form within a reasonably prompt period of time. The
Trustee is hereby appointed “Note Registrar” for the purpose of registering Notes and transfers of
Notes as herein provided. The Issuer may appoint one or more co-registrars in accordance with
Section 4.02.

Upon surrender for registration of transfer of any Note to the Note Registrar or any
co-registrar, and satisfaction of the requirements for such transfer set forth in this Section
2.05, the Issuer shall execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Notes of any authorized denominations and of
a like aggregate principal amount and bearing such restrictive legends as may be required by this
Indenture.

Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate
principal amount, upon surrender of the Notes to be exchanged at any such office or agency
maintained by the Issuer pursuant to Section 4.02. Whenever any Notes are so surrendered for
exchange, the Issuer shall execute, and the Trustee shall authenticate and deliver, the Notes which
the Noteholder making the exchange is entitled to receive bearing registration numbers not
contemporaneously outstanding.

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

All Notes presented or surrendered for registration of transfer or exchange, repurchase or
conversion shall (if so required by the Issuer or the Note Registrar) be duly endorsed, or be
accompanied by a written instrument or instruments of transfer in form satisfactory to the Issuer,
and the Notes shall be duly executed by the Noteholder thereof or its attorney duly authorized in
writing.

No service charge shall be made to any holder for any registration of transfer or exchange of
Notes, but the Issuer may require payment by the holder of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in connection with any registration of
transfer or exchange of Notes.

In connection with the redemption of the Notes in part, neither the Trustee nor any Note
Registrar shall be required to issue or register the transfer or exchange of (i) any Notes during a
period beginning at the opening of business fifteen (15) days before any selection of Notes to be
redeemed and ending at the close of business on the day of mailing of the relevant notice of
redemption, or (ii) any Notes or portions thereof called for redemption pursuant to Section 3.02,
except the unredeemed portion of any Note redeemed in part.

(b) The following provisions shall apply only to Global Notes:

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

(ii) Notwithstanding any other provision in this Indenture, no Global Note may be
exchanged in whole or in part for Notes registered, and no transfer of a Global Note in
whole or in part may be registered, in the name of any Person other than the Depositary or a
nominee thereof unless (1) the Depositary (x) has notified the Issuer that it is unwilling
or unable to continue as Depositary for such Global Note or (y) has ceased to be a clearing
agency registered under the Exchange Act, and a successor depositary has not been appointed
by the Issuer within ninety (90) calendar days, (2) a Holder, if an Event of Default has
occurred and is continuing, or (3) the Issuer, in its sole discretion, notifies the Trustee
in writing that it no longer wishes to have all the Notes represented by Global Notes. Any
Global Note exchanged pursuant to clause (1) or (2) above shall be so exchanged in whole and
not in part and any Global Note exchanged pursuant to clause (3) above may be exchanged in
whole or from time to time in part as directed by the Issuer. Any Note issued in exchange
for a Global Note or any portion thereof shall be a Global Note; provided that any such Note
so issued that is registered in the name of a Person other than the Depositary or a nominee
thereof shall not be a Global Note.

(iii) Notes issued in exchange for a Global Note or any portion thereof pursuant to
clause (ii) above shall be issued in definitive, fully registered form, without interest
coupons, shall have an aggregate principal amount equal to that of such Global Note or
portion thereof to be so exchanged, shall be registered in such names and be in such
authorized denominations as the Depositary shall designate and shall bear any legends
required hereunder. Any Global Note to be exchanged in whole shall be surrendered by the
Depositary to the Trustee, as Note Registrar. With regard to any Global Note to be
exchanged in part, either such Global Note shall be so surrendered for exchange or, if the
Trustee is acting as Custodian for the Depositary or its nominee with respect to such Global
Note, the principal amount thereof shall be reduced, by an amount equal to the portion
thereof to be so exchanged, by means of an appropriate adjustment made on the records of the
Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and make
available for delivery the Note issuable on such exchange to or upon the written order of
the Depositary or an authorized representative thereof.

(iv) In the event of the occurrence of any of the events specified in clause (ii)
above, the Issuer will promptly make available to the Trustee a reasonable supply of
certificated Notes in definitive, fully registered form, without interest coupons.

(v) Neither any members of, or participants in, the Depositary (“Agent Members”) nor
any other Persons on whose behalf Agent Members may act shall have any rights under this
Indenture with respect to any Global Note registered in the name of the Depositary or any
nominee thereof, and the Depositary or such nominee, as the case may be, may be treated by
the Issuer, the Trustee and any agent of the Issuer or the Trustee as the absolute owner and
holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the
Trustee from giving effect to any written certification, proxy or other authorization
furnished by the Depositary or such nominee, as the case may be, or impair, as between the
Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act,
the operation of customary practices of such Persons governing the exercise of the rights of
a holder of any Note.

(vi) At such time as all interests in a Global Note have been redeemed, repurchased,
converted or exchanged for Notes in certificated form, such Global Note shall, upon receipt
thereof, be canceled by the Trustee in accordance with standing procedures and instructions
existing between the Depositary and the Custodian. At any time prior to such cancellation,
if any interest in a Global Note is redeemed, repurchased, converted or exchanged for Notes
in certificated form, the principal amount of such Global Note shall, in accordance with the
standing procedures and instructions existing between the Depositary and the Custodian, be
appropriately reduced, and an endorsement shall be made on such Global Note, by the Trustee
or the Custodian, at the direction of the Trustee, to reflect such reduction.

(c) Every Note (and all securities issued in exchange therefor or in substitution thereof)
that bears or is required under this Section 2.05(c) to bear the legend set forth in this Section
2.05(c) (together with any Common Shares issued upon conversion of the Notes, collectively, the
“Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section
2.05(c) (including those set forth in the legend below) unless such restrictions on transfer shall
be waived by written consent of the Issuer, and the holder of each such Restricted Security, by
such Noteholder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As
used in this Section 2.05(c), the term “transfer” means any sale, pledge, loan, transfer or other
disposition whatsoever of any Restricted Security or any interest therein.

Until the expiration of the holding period applicable to sales of Restricted Securities under
Rule 144(k) under the Securities Act (or any successor provision), any certificate evidencing a
Restricted Security shall bear a legend in substantially the following form, unless such Restricted
Security has been sold pursuant to a registration statement that has been declared effective under
the Securities Act (and which continues to be effective at the time of such transfer) or sold
pursuant to Rule 144 under the Securities Act or any similar provision then in force, or unless
otherwise agreed by the Issuer in writing, with written notice thereof to the Trustee:

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), OR ANY STATE SECURITIES LAWS, AND MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE
FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER:

(1) REPRESENTS THAT IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS
DEFINED IN RULE 144A UNDER THE SECURITIES ACT), IS AWARE THAT THE
TRANSFER TO IT IS BEING MADE IN RELIANCE ON RULE 144A UNDER THE
SECURITIES ACT AND IS ACQUIRING THIS SECURITY IN COMPLIANCE WITH
RULE 144A UNDER THE SECURITIES ACT;

(2) AGREES THAT IT WILL NOT, WITHIN TWO YEARS AFTER THE LATER
OF THE ORIGINAL ISSUE DATE OF THIS SECURITY AND THE LAST DATE ON
WHICH RAIT FINANCIAL TRUST OR AN AFFILIATE THEREOF WAS THE OWNER OF
THIS SECURITY, RESELL OR OTHERWISE TRANSFER THIS SECURITY OR THE
COMMON SHARES ISSUABLE UPON CONVERSION OF SUCH SECURITY EXCEPT (A)
TO RAIT FINANCIAL TRUST OR ANY OF ITS SUBSIDIARIES, (B) FOR SO LONG
AS THE NOTES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A
PERSON IT REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER
THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED
INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS
BEING MADE IN RELIANCE ON RULE 144A, (C) PURSUANT TO ANY OTHER
AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT, OR (D) PURSUANT TO A REGISTRATION STATEMENT WHICH
HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT AND WHICH
CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH RESALE OR TRANSFER,
SUBJECT, IN EACH CASE TO COMPLIANCE WITH ANY APPLICABLE STATE
SECURITIES LAWS; AND

(3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS
SECURITY IS TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE
2(D) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN
CONNECTION WITH ANY TRANSFER OF THIS SECURITY WITHIN TWO YEARS AFTER
THE LATER OF THE ORIGINAL ISSUE DATE OF THIS SECURITY AND THE LAST
DATE ON WHICH RAIT FINANCIAL TRUST OR AN AFFILIATE THEREOF WAS THE
OWNER OF THIS SECURITY, THE HOLDER MUST CHECK THE APPROPRIATE BOX
SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH
TRANSFER AND SUBMIT THIS SECURITY TO THE TRUSTEE (OR ANY SUCCESSOR
TRUSTEE, AS APPLICABLE). IF THE PROPOSED TRANSFER IS PURSUANT TO
CLAUSE 2(C) ABOVE, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH
TO THE TRUSTEE (OR ANY SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH
CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS RAIT
FINANCIAL TRUST OR THE TRUSTEE MAY REASONABLY REQUIRE TO CONFIRM
THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR
IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF
THE SECURITIES ACT. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF
THE TRANSFER OF THIS SECURITY PURSUANT TO CLAUSE 2(D) ABOVE OR THE
EXPIRATION OF TWO YEARS FROM THE LATER OF THE ORIGINAL ISSUE DATE OF
THIS SECURITY AND THE LAST DATE ON WHICH RAIT FINANCIAL TRUST OR AN
AFFILIATE THEREOF WAS THE OWNER OF THIS SECURITY.

THE HOLDER OF THIS SECURITY IS ENTITLED TO THE BENEFITS OF A
REGISTRATION RIGHTS AGREEMENT (AS SUCH TERM IS DEFINED IN THE
INDENTURE REFERRED TO ON THE REVERSE HEREOF) AND, BY ITS ACCEPTANCE
HEREOF, AGREES TO BE BOUND BY AND TO COMPLY WITH THE PROVISIONS OF
SUCH REGISTRATION RIGHTS AGREEMENT.

Any Notes that are Restricted Securities and as to which such restrictions on transfer shall
have expired in accordance with their terms or as to conditions for removal of the foregoing legend
set forth therein have been satisfied may, upon surrender of such Note for exchange to the Note
Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or
Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend
required by this Section 2.05(c). If such Restricted Security surrendered for exchange is
represented by a Global Note bearing the legend set forth in this Section 2.05(c), the principal
amount of the legended Global Note shall be reduced by the appropriate principal amount and the
principal amount of a Global Note without the legend set forth in this Section 2.05(c) shall be
increased by an equal principal amount. If a Global Note without the legend set forth in this
Section 2.05(c) is not then outstanding, the Issuer shall execute and the Trustee shall
authenticate and deliver an unlegended Global Note to the Depositary.

In the event Rule 144(k) under the Securities Act (or any successor provision) is amended to
shorten the two-year period under Rule 144(k), then, the references in the restrictive legends set
forth above to “TWO YEARS,” and in the corresponding transfer restrictions described above, and in
the Notes and the Common Shares will be deemed to refer to such shorter period, from and after
receipt by the Trustee of an Officers’ Certificate and an Opinion of Counsel to that effect. As
soon as reasonably practicable after the Issuer knows of the effectiveness of any such amendment to
shorten the two-year period under Rule 144(k), unless such changes would otherwise be prohibited
by, or would cause a violation of, the federal securities laws applicable at the time, the Issuer
will provide to the Trustee an Officers’ Certificate and an Opinion of Counsel as to the
effectiveness of such amendment and the effectiveness of such change to the restrictive legends and
transfer restrictions.

(d) The Issuer or any of its affiliates may, to the extent permitted by applicable law, at any
time purchase Notes in the open market, by tender at any price or by private agreement. Any Note
purchased by the Issuer or any of its affiliates (a) after the date that is two years from the
latest issuance of the Notes may, to the extent permitted by applicable law, be reissued or sold or
may be surrendered to the Trustee for cancellation or (b) on or prior to the date in clause (a),
shall be surrendered to the Trustee for cancellation. Any Notes surrendered for cancellation may
not be reissued or resold and shall be canceled promptly.

(e) The Trustee shall have no responsibility or obligation to any Agent Members or any other
Person with respect to the accuracy of the books or records, or the acts or omissions, of the
Depositary or its nominee or of any participant or member thereof, with respect to any ownership
interest in the Notes or with respect to the delivery to any Agent Member or other Person (other
than the Depositary) of any notice (including any notice of redemption) or the payment of any
amount, under or with respect to such Notes. All notices and communications to be given to the
Noteholders and all payments to be made to Noteholders under the Notes shall be given or made only
to or upon the order of the registered Noteholders (which shall be the Depositary or its nominee in
the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised
only through the Depositary subject to the customary procedures of the Depository. The Trustee may
rely and shall be fully protected in relying upon information furnished by the Depositary with
respect to its Agent Members.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance
with any restrictions on transfer imposed under this Indenture or under applicable law with respect
to any transfer of any interest in any Note (including any transfers between or among Agent Members
in any Global Indenture) other than to require delivery of such certificates and other
documentation or evidence as are expressly required by, and to do so if and when expressly required
by, the terms of this Indenture, and to examine the same to determine substantial compliance as to
form with the express requirements hereof.

Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated
or be destroyed, lost or stolen, the Issuer in its discretion may execute, and upon its written
request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and make
available for delivery, a new Note, bearing a number not contemporaneously outstanding, in exchange
and substitution for the mutilated Note, or in lieu of and in substitution for the Note so
destroyed, lost or stolen, and each Guarantor shall execute a replacement Guarantee. In every
case, the applicant for a substituted Note shall furnish to the Issuer, to the Trustee and, if
applicable, to such authenticating agent such security or indemnity as may be required by them to
save each of them harmless for any loss, liability, cost or expense caused by or connected with
such substitution, and, in every case of destruction, loss or theft, the applicant shall also
furnish to the Issuer, to the Trustee and, if applicable, to such authenticating agent evidence to
their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

Following receipt by the Trustee or such authenticating agent, as the case may be, of
satisfactory security or indemnity and evidence, as described in the preceding paragraph, the
Trustee or such authenticating agent may authenticate any such substituted Note and make available
for delivery such Note. Upon the issuance of any substituted Note, the Issuer may require the
payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge
that may be imposed in relation thereto and any other expenses connected therewith. In case any
Note which has matured or is about to mature or has been called for redemption or has been properly
tendered for repurchase on a Change in Control Repurchase Date (and not withdrawn), as the case may
be, or is to be converted pursuant to this Indenture, shall become mutilated or be destroyed, lost
or stolen, the Issuer may, instead of issuing a substitute Note, pay or authorize the payment of or
authorize the conversion of the same (without surrender thereof except in the case of a mutilated
Note), as the case may be, if the applicant for such payment or conversion shall furnish to the
Issuer, to the Trustee and, if applicable, to such authenticating agent such security or indemnity
as may be required by them to save each of them harmless for any loss, liability, cost or expense
caused by or in connection with such substitution, and, in every case of destruction, loss or
theft, the applicant shall also furnish to the Issuer, the Trustee and, if applicable, any Paying
Agent or Conversion Agent evidence to their satisfaction of the destruction, loss or theft of such
Note and of the ownership thereof.

Every substitute Note and Guarantee issued pursuant to the provisions of this Section 2.06 by
virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional
contractual obligation of the Issuer and each Guarantor, whether or not the destroyed, lost or
stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be
subject to all the limitations set forth in) this Indenture equally and proportionately with any
and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held
and owned upon the express condition that the foregoing provisions are exclusive with respect to
the replacement or payment or exchange or redemption or repurchase of mutilated, destroyed, lost or
stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or
statute existing or hereafter enacted to the contrary with respect to the replacement or payment or
exchange or redemption or repurchase of negotiable instruments or other securities without their
surrender.

Section 2.07. Temporary Notes. Pending the preparation of Notes in certificated form, the Issuer
may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon the
written request of the Issuer, authenticate and deliver temporary Notes (printed or lithographed).
Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of
the Notes in certificated form, but with such omissions, insertions and variations as may be
appropriate for temporary Notes, all as may be determined by the Issuer. Every such temporary Note
shall be executed by the Issuer and authenticated by the Trustee or such authenticating agent upon
the same conditions and in substantially the same manner, and with the same effect, as the Notes in
certificated form. Without unreasonable delay, the Issuer will execute and deliver to the Trustee
or such authenticating agent Notes in certificated form and thereupon any or all temporary Notes
may be surrendered in exchange therefor, at each office or agency maintained by the Issuer pursuant
to Section 4.02 and the Trustee or such authenticating agent shall authenticate and make available
for delivery in exchange for such temporary Notes an equal aggregate principal amount of Notes in
certificated form. Such exchange shall be made by the Issuer at its own expense and without any
charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the
same benefits and subject to the same limitations under this Indenture as Notes in certificated
form authenticated and delivered hereunder.

Section 2.08. Cancellation of Notes.All Notes surrendered for the purpose of payment, redemption,
repurchase, conversion, exchange or registration of transfer shall, if surrendered to the Issuer or
any paying agent to whom Notes may be presented for payment (the “Paying Agent”) or Conversion
Agent, which shall initially be the Trustee, or any Note Registrar, be surrendered to the Trustee
and promptly canceled by it or, if surrendered to the Trustee, shall be promptly canceled by it and
no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of
this Indenture. The Trustee shall dispose of such canceled Notes in accordance with its customary
procedures. If the Issuer shall acquire any of the Notes, such acquisition shall not operate as a
redemption, repurchase or satisfaction of the indebtedness represented by such Notes unless and
until the same are delivered to the Trustee for cancellation.

Section 2.09. CUSIP Numbers. The Issuer in issuing the Notes may use “CUSIP” numbers (if then
generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a
convenience to Noteholders; provided that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Notes or as contained in any notice
of a redemption and that reliance may be placed only on the other identification numbers printed on
the Notes, and any such redemption shall not be affected by any defect in or omission of such
numbers. The Issuer will promptly notify the Trustee of any change in the “CUSIP” numbers.

ARTICLE 3

Redemption and Repurchase of Notes

Section 3.01. Optional Redemption of Notes. The Issuer shall not have the right to redeem any
Notes prior to April 20, 2012, except to preserve the Issuer’s status as a real estate investment
trust on the terms set forth in this Section 3.01. If, at any time, the Issuer determines it is
necessary to redeem the Notes in order to preserve its status as a real estate investment trust,
the Issuer may, upon the notice set forth in Section 3.02, redeem the Notes for cash, in whole or
in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed
plus unpaid interest (including Additional Interest and Special Interest, if any), if any, accrued
thereon to the Redemption Date; provided that, in connection with any such redemption, the Issuer
shall provide the Trustee with an Officers’ Certificate evidencing that the Board of Trustees has,
in good faith, made the determination that it is necessary to redeem the Notes in order to preserve
the Issuer’s status as a real estate investment trust.

The Issuer shall have the right to redeem the Notes, in whole or in part at any time or from
time to time, on or after April 20, 2012 at a redemption price for cash equal to 100% of the
principal amount of the Notes to be redeemed plus unpaid interest (and Additional Interest and
Special Interest, if any), if any, accrued thereon to the Redemption Date.

Section 3.02. Notice of Optional Redemption; Selection of Notes. In case the Issuer shall desire
to exercise the right to redeem all or, as the case may be, any part of the Notes pursuant to
Section 3.01, it shall fix a date for redemption and it or, at its written request received by the
Trustee not fewer than five (5) Business Days prior (or such shorter period of time as may be
acceptable to the Trustee) to the date the notice of redemption is to be mailed, the Trustee in the
name of and at the expense of the Issuer, shall mail or cause to be mailed a notice of such
redemption not fewer than thirty (30) calendar days nor more than sixty (60) calendar days prior to
the Redemption Date to each holder of Notes so to be redeemed in whole or in part at its last
address as the same appears on the Note Register; provided that if the Issuer makes such request of
the Trustee, the text of the notice shall be prepared by the Issuer. Such mailing shall be by
first class mail. The notice, if mailed in the manner herein provided, shall be conclusively
presumed to have been duly given, whether or not the holder receives such notice. In any case,
failure to give such notice by mail or any defect in the notice to the holder of any Note
designated for redemption as a whole or in part shall not affect the validity of the proceedings
for the redemption of any other Note. Concurrently with the mailing of any such notice of
redemption, the Issuer shall issue a press release announcing such redemption, the form and content
of which press release shall be determined by the Issuer in its sole discretion. The failure to
issue any such press release or any defect therein shall not affect the validity of the redemption
notice or any of the proceedings for the redemption of any Note called for redemption.

Each such notice of redemption shall specify: (i) the aggregate principal amount of Notes to
be redeemed; (ii) the CUSIP number or numbers of the Notes being redeemed; (iii) the date fixed for
redemption (which shall be a Business Day); (iv) the redemption price at which Notes are to be
redeemed; (v) the place or places of payment and that payment will be made upon presentation and
surrender of such Notes; (iv) that interest accrued and unpaid to the date fixed for redemption
will be paid as specified in said notice, and that on and after said date interest thereon or on
the portion thereof to be redeemed will cease to accrue; (vii) that the holder has a right to
convert the Notes called for redemption; (viii) the Conversion Rate on the date of such notice; and
(ix) the time and date on which the right to convert such Notes or portions thereof pursuant to
this Indenture will expire. If fewer than all the Notes are to be redeemed, the notice of
redemption shall identify the Notes to be redeemed (including CUSIP numbers, if any). In case any
Note is to be redeemed in part only, the notice of redemption shall state the portion of the
principal amount thereof to be redeemed and shall state that, on and after the Redemption Date,
upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed
portion thereof will be issued.

Whenever any Notes are to be redeemed, the Issuer shall give the Trustee written notice of the
Redemption Date, together with an Officers’ Certificate as to the aggregate principal amount of
Notes to be redeemed, not fewer than thirty (30) calendar days prior to the Redemption Date.

On or prior to the Redemption Date specified in the notice of redemption given as provided in
this Section 3.02, the Issuer shall deposit with the Paying Agent (or, if the Issuer is acting as
its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.04) an amount
of money in immediately available funds sufficient to redeem on the Redemption Date all the Notes
(or portions thereof) so called for redemption (other than those theretofore surrendered for
exchange) at the appropriate redemption price, together with accrued interest to the Redemption
Date; provided that if such payment is made on the Redemption Date, it must be received by the
Paying Agent, by 11:00 a.m., New York City time, on such date. The Issuer shall be entitled to
retain any amounts deposited with the Paying Agent pursuant to this Section 3.02 in excess of
amounts required hereunder to pay the redemption price and accrued interest to the Redemption Date.
If any Note called for redemption is converted pursuant hereto prior to such Redemption Date, any
money deposited with the Paying Agent or so segregated and held in trust for the redemption of such
Note shall be paid to the Issuer or, if then held by the Issuer, shall be discharged from such
trust.

If less than all of the outstanding Notes are to be redeemed, the Trustee shall select the
Notes or portions thereof of the Global Note or the Notes in certificated form to be redeemed (in
principal amounts of $1,000 or multiples thereof) on a pro rata basis or by another method the
Trustee deems fair and appropriate. If any Note selected for redemption in part is submitted for
conversion in part after such selection, the portion of such Note submitted for conversion shall be
deemed (so far as may be possible) to be the portion to be selected for redemption. The Notes (or
portions thereof) so selected for redemption shall be deemed duly selected for redemption for all
purposes hereof, notwithstanding that any such Note is submitted for conversion in part before the
mailing of the notice of redemption.

Upon any redemption of less than all of the outstanding Notes, the Issuer and the Trustee may
(but need not), solely for purposes of determining the pro rata allocation among such Notes that
are outstanding at the time of redemption, treat as outstanding any Notes surrendered for
conversion during the period in which Notes are selected for redemption.

Section 3.03. Payment of Notes Called for Redemption by the Issuer. If notice of redemption has
been given as provided in Section 3.02, the Notes or portion of Notes with respect to which such
notice has been given shall, unless converted pursuant to the terms hereof, become due and payable
on the date fixed for redemption at the place or places stated in such notice at the redemption
price, plus interest accrued to the Redemption Date, and unless the Issuer shall default in the
payment of the amounts owing on the Notes upon such redemption, interest on the Notes or portion of
Notes so called for redemption shall cease to accrue on and after such date and, except as provided
in Section 7.05 and Section 11.02, the Notes shall cease to be entitled to any benefit or security
under this Indenture, and the holders thereof shall have no right in respect of such Notes except
the right to receive the redemption price thereof plus accrued and unpaid interest to the
Redemption Date. On presentation and surrender of such Notes at a place of payment in said notice
specified, the said Notes or the specified portions thereof shall be paid and redeemed by the
Issuer at the redemption price, together with interest accrued thereon to the Redemption Date.

Upon presentation of any Note redeemed in part only, the Issuer shall execute and the Trustee
shall authenticate and make available for delivery to the holder thereof, at the expense of the
Issuer, a new Note or Notes, of authorized denominations, in principal amount equal to the
unredeemed portion of the Notes so presented.

Notes and portions of Notes that are to be redeemed pursuant to this Article 3 shall be
convertible by the Holder thereof until 5:00 p.m., New York City time, on the second Business Day
immediately preceding the Redemption Date, unless the Issuer shall fail to pay the redemption
price.

	 	 	 
	Section 3.04. Sinking Fund. There shall be no sinking fund provided for the Notes.

	 
	 	 
	Section 3.05.

	 	Repurchase at Option of Holders Upon a Change in Control.

(a) If a Change in Control occurs at any time prior to April 20, 2012, a holder of Notes shall
have the right to require the Issuer to repurchase such holder’s Notes, in whole or in part (in
principal amounts of $1,000 or an integral multiple thereof) for cash equal to 100% of the
principal amount of the Notes to be repurchased, plus unpaid interest (including Additional
Interest and Special Interest, if any), if any, accrued thereon to the Change in Control Repurchase
Date (such amount, the “Change in Control Purchase Price”), subject to satisfaction by or on behalf
of the holder of the requirements set forth below. If a Change in Control occurs on or after April
20, 2012, holders of Notes will not have any right to require the Issuer to repurchase its Notes,
except in accordance with Section 3.06.

(b) Within 30 days after the occurrence of a Change in Control, the Issuer shall mail a
written notice of the particular Change in Control and of the repurchase right arising as a result
of such Change in Control (the “Issuer Notice”) by first-class mail to the Trustee, any Paying
Agent and to each holder (and to beneficial owners to the extent required by applicable law). The
notice shall include a form of Change in Control Purchase Notice (defined below) to be completed by
the holder and shall state:

(1) briefly, the events causing a Change in Control and the date of such Change in Control;

(2) the date by which the Change in Control Purchase Notice must be delivered to the Paying
Agent;

(3) the date on which the Issuer will repurchase Notes upon a Change in Control, which must be
not less than 15 days nor more than 30 days after the date of the Issuer Notice (such date, the
“Change in Control Repurchase Date”);

(4) the Change in Control Purchase Price;

(5) the name and address of the Trustee, the Paying Agent and the Conversion Agent;

(6) that Notes in respect of which a Change in Control Purchase Notice is provided by a Holder
shall not be convertible unless such holder validly withdraws such Change in Control Purchase
Notice in accordance with the provisions of this Section 3.05;

(7) that Notes must be surrendered to the Paying Agent to collect payment of the Change in
Control Purchase Price;

(8) that the Change in Control Purchase Price for any Note as to which a Change in Control
Purchase Notice has been duly given will be paid within two Business Days after the later of the
Change in Control Repurchase Date or the time at which such Notes are surrendered for repurchase;

(9) that, unless the Issuer defaults in making payment of the Change in Control Purchase
Price, interest on Notes surrendered for repurchase will cease to accrue on and after the Change in
Control Repurchase Date; and

(10) the CUSIP number of the Notes.

The Issuer shall also disseminate a press release through Dow Jones & Company, Inc. or
Bloomberg Business News announcing the occurrence of such Change in Control or publish such
information in a newspaper of general circulation in The City of New York or on the Issuer’s
website, or through such other public medium as the Issuer shall deem appropriate at such time.

(c) A holder may exercise its rights specified in this Section 3.05 upon delivery of a written
notice of such holder’s exercise of its repurchase right (a “Change in Control Purchase Notice”) to
the Paying Agent at any time prior to the close of business on the third Business Day prior to the
Change in Control Repurchase Date, stating:

(1) if such Notes are in certificated form, the certificate number(s) of the Notes which the
Holder will deliver to be repurchased;

(2) the portion of the principal amount of the Notes to be repurchased, in multiples of
$1,000, provided that the remaining principal amount of Notes is in an authorized denomination; and

(3) that such Note shall be repurchased pursuant to the applicable provisions hereof and of
the Notes.

The Paying Agent shall promptly notify the Issuer in writing of the receipt by it of any
Change in Control Purchase Notice.

(d) Book-entry transfer of Notes in book-entry form in compliance with appropriate procedures
of the Depositary or delivery of Notes in certificated form (together with all necessary
endorsements) to the Paying Agent on or after the Change in Control Repurchase Date at the offices
of the Paying Agent shall be a condition to the receipt by the holder of the Change in Control
Purchase Price therefor. Holders electing to require the Issuer to repurchase Notes must effect
such transfer or delivery to the Paying Agent prior to the Change in Control Repurchase Date to
receive payment of the Change in Control Purchase Price on or within two Business Days after the
Change in Control Repurchase Date. The Issuer shall pay the Change in Control Purchase Price after
the later of the Change in Control Repurchase Date and the date that is two Business Days after the
time of such transfer or delivery of the Notes.

(e) A Change in Control Purchase Notice may be withdrawn in whole or in part by a holder by
means of a written notice of withdrawal delivered to the office of the Paying Agent prior to the
close of business on the third Business Day prior to the Change in Control Repurchase Date
specifying:

(1) the holder’s name;

(2) the principal amount of Notes in respect of which the Change in Control Purchase Notice is
being withdrawn, which must be an integral multiple of $1,000;

(3) if the Notes subject to the notice of withdrawal are in certificated form, the certificate
number(s) of all Notes subject to the notice of withdrawal; and

(4) the principal amount of Notes, if any, that remains subject to the Change in Control
Purchase Notice, which must be an integral multiple of $1,000.

If Notes subject to the notice of withdrawal are in book-entry form, the above notices must
also comply with the applicable procedures of the Depositary.

(f) On or before 10:00 a.m. (New York City time) on the Change in Control Repurchase Date, the
Issuer shall deposit with the Paying Agent (or if the Issuer or an Affiliate of the Issuer is
acting as the Paying Agent, shall segregate and hold in trust) money sufficient to pay the
aggregate Change in Control Purchase Price of the Notes to be repurchased pursuant to this Section
3.05. If the Paying Agent holds, in accordance with the terms of this Indenture, money sufficient
to pay the Change in Control Purchase Price of such Notes on the Change in Control Repurchase Date,
then, on and after such date, such Notes shall cease to be Outstanding and interest on such Notes
shall cease to accrue and all rights of the holders of such Notes shall terminate (other than the
right to receive the Change in Control Purchase Price after delivery or transfer of the Notes).
Such will be the case whether or not book-entry transfer of the Notes in book-entry form is made
and whether or not Notes in certificated form, together with the necessary endorsements, are
delivered to the Paying Agent.

(g) Notwithstanding the foregoing, no Notes may be repurchased by the Issuer in accordance
with the provisions of this Section 3.05 if there has occurred and is continuing an Event of
Default with respect to the Notes (other than a default in the payment of the Change in Control
Purchase Price).

(h) To the extent legally required in connection with a repurchase of Notes, the Issuer shall
comply with the provisions of Rule 13e-4 and other tender offer rules under the Exchange Act then
applicable, if any, and will file a Schedule TO or any other schedule required under the Exchange
Act.

(i) The Issuer may arrange for a third party to purchase Notes for which the Issuer has
received a valid Change in Control Purchase Notice that has not been properly withdrawn, in the
manner and otherwise in compliance with the requirements set forth herein and in the Notes
(including, without limitation, any applicable restrictions on transfer); provided that the Issuer
shall give written notice to the Trustee of such third party arrangement not less than one Business
Day prior to the Change in Control Repurchase Date, which notice shall, at a minimum, identify such
third party and identify the Notes to be so purchased (and which shall remain Outstanding as
provided in the next sentence). If a third party purchases any Notes under such circumstances, then
interest will continue to accrue on the Notes and such Notes will continue to be Outstanding after
the Change in Control Repurchase Date for all purposes of the Indenture and will be fungible with
all other Notes then Outstanding.

Section 3.06. Repurchase at Option of Holders on Certain Dates.

(a) A holder of Notes shall have the right to require the Issuer to repurchase such holder’s
Notes, in whole or in part (in principal amounts of $1,000 or an integral multiple thereof), on
each of April 15, 2012, April 15, 2017 and April 15, 2022 (each, an “Optional Repurchase Date”) for
cash equal to 100% of the principal amount of the Notes to be repurchased plus unpaid interest
(including Additional Interest and Special Interest, if any) accrued thereon to the Optional
Repurchase Date (such amount, the “Optional Repurchase Price”), subject to satisfaction by or on
behalf of the holder of the requirements set forth below.

(b) On or before the 30th day prior to each Optional Repurchase Date, the Issuer shall provide
a written notice by first-class mail to the Trustee, any Paying Agent and all holders (and to
beneficial owners to the extent required by applicable law). The notice shall include a form of
Optional Repurchase Notice to be completed by the holder and shall state:

(1) the date by which the Optional Repurchase Notice must be delivered to the Paying Agent;

(2) the Optional Repurchase Date;

(3) the Optional Repurchase Price;

(4) the name and address of the Trustee, the Paying Agent and the Conversion Agent;

(5) that Notes must be surrendered to the Paying Agent to collect payment of the Optional
Repurchase Price;

(6) that the Optional Repurchase Price for any Note as to which an Optional Repurchase Notice
has been duly given will be paid within two Business Days after the later of the Optional
Repurchase Date or the time at which such Notes are surrendered for repurchase;

(7) that, unless the Issuer defaults in making payment of the Optional Repurchase Price,
interest on Notes surrendered for repurchase will cease to accrue on and after the Optional
Repurchase Date;

(8) that Notes in respect of which an Optional Repurchase Notice is provided by a Holder shall
not be convertible in accordance with their terms even if otherwise convertible unless such Holder
validly withdraws such Optional Repurchase Notice in accordance with the provisions of this Section
3.06; and

(9) the CUSIP number of the Notes.

The Issuer shall also disseminate a press release through Dow Jones & Company, Inc. or
Bloomberg Business News containing the information specified in such notice or publish such
information in a newspaper of general circulation in The City of New York or on the Issuer’s
website, or through such other public medium as the Issuer shall deem appropriate at such time.

(c) A holder may exercise its rights specified in this Section 3.06 upon delivery of a written
notice of repurchase (an “Optional Repurchase Notice”) to the Paying Agent during the period
beginning at any time from the opening of business on the date that is 30 days prior to the
applicable Optional Repurchase Date until the close of business on the third Business Day prior to
such Optional Repurchase Date, stating:

(1) if such Notes are in certificated form, the certificate number(s) of the Notes which the
holder will deliver to be repurchased;

(2) the portion of the principal amount of the Notes to be repurchased, in integral multiples
of $1,000, provided that the remaining principal amount of Notes is in an authorized denomination;
and

(3) that such Notes shall be repurchased pursuant to the applicable provisions hereof and the
Notes.

The Paying Agent shall promptly notify the Issuer in writing of the receipt by it of any
Optional Repurchase Notice.

(d) Book-entry transfer of Notes in book-entry form in compliance with appropriate procedures
of the Depositary or delivery of Notes in certificated form, together with all necessary
endorsements, to the Paying Agent on or after the Optional Repurchase Date at the offices of the
Paying Agent shall be a condition to the receipt by the holder of the Optional Repurchase Price
therefor. Holders electing to require the Issuer to repurchase Notes must effect such transfer or
delivery to the Paying Agent prior to the Optional Repurchase Date to receive payment of the
Optional Repurchase Price on or within two Business Days after the Optional Repurchase Date. The
Issuer shall pay the Optional Repurchase Price within two Business Days after the later of the
Optional Repurchase Date or the time of such transfer or delivery of the Notes.

(e) An Optional Repurchase Notice may be withdrawn in whole or in part by a holder by means of
a written notice of withdrawal delivered to the office of the Paying Agent prior to the close of
business on the third Business Day prior to the Optional Repurchase Date specifying:

(1) the holder’s name;

(2) the principal amount of Notes in respect of which the Optional Repurchase Notice is being
withdrawn, which must be an integral multiple of $1,000;

(3) if the Notes subject to the notice of withdrawal are in certificated form, the certificate
number(s) of all Notes subject to the notice of withdrawal; and

(4) the principal amount of Notes, if any, that remains subject to the Optional Repurchase
Notice, which must be an integral multiple of $1,000.

If Notes subject to the notice of withdrawal are in book-entry form, the above notices must
also comply with the applicable procedures of the Depositary.

(f) On or before 10:00 a.m. (New York City time) on the Optional Repurchase Date, the Issuer
shall deposit with the Paying Agent (or if the Issuer or an Affiliate of the Issuer is acting as
the Paying Agent, shall segregate and hold in trust) money sufficient to pay the aggregate Optional
Repurchase Price of the Notes to be repurchased pursuant to this Section 3.06. If the Paying Agent
holds, in accordance with the terms of the Indenture, money sufficient to pay the Optional
Repurchase Price of such Notes on the Optional Repurchase Date, then on and after such date, such
Notes shall cease to be Outstanding and interest on such Notes shall cease to accrue, and all
rights of the Holder of such Notes shall terminate (other than the right to receive the Optional
Repurchase Price after delivery or transfer of the Notes). Such will be the case whether or not
book-entry transfer of the Notes in book-entry form is made and whether or not Notes in
certificated form, together with the necessary endorsements, are delivered to the Paying Agent.

(g) Notwithstanding the foregoing, no Notes may be repurchased by the Issuer in accordance
with the provisions of this Section 3.06 if there has occurred and is continuing an Event of
Default with respect to the Notes (other than a default in the payment of the Optional Repurchase
Price).

(h) To the extent legally required in connection with a repurchase of Notes, the Issuer shall
comply with the provisions of Rule 13e-4 and other tender offer rules under the Exchange Act then
applicable, if any, and will file a Schedule TO or any other schedule required under the Exchange
Act.

(i) The Issuer may arrange for a third party to purchase Notes for which the Issuer has
received a valid Optional Repurchase Notice that has not been properly withdrawn, in the manner and
otherwise in compliance with the requirements set forth herein and in the Notes (including, without
limitation, any applicable restrictions on transfer); provided that the Issuer shall give written
notice to the Trustee of such arrangement not less than one Business Day prior to the Optional
Repurchase Date, which notice shall, at a minimum, identify such third party and identify the Notes
to be so purchased (and which shall continue to be Outstanding, as provided in the next sentence).
If a third party purchases any Notes under such circumstances, then interest will continue to
accrue on the Notes and such Notes will continue to be Outstanding after the Optional Repurchase
Date for all purposes of the Indenture and will be fungible with all other Notes then Outstanding.

Section 3.07. Notes Repurchased in Part. Upon presentation of any Note repurchased only in part,
the Issuer shall execute and the Trustee shall authenticate and make available for delivery to the
holder thereof, at the expense of the Issuer, a new Note or Notes, of any authorized denomination,
in aggregate principal amount equal to the unrepurchased portion of the Notes presented.

Section 3.08. Repayment to the Issuer. Subject to Section 11.04, the Paying Agent shall return to
the Issuer any cash that remains unclaimed thereon, held by them for the payment of the Change in
Control Purchase Price or Optional Repurchase Price; provided that to the extent that the aggregate
amount of cash deposited by the Issuer pursuant to Sections 3.05 or 3.06 exceeds the aggregate
repurchase price of the Notes or portions thereof which the Issuer is obligated to repurchase as of
the Change in Control Repurchase Date or Optional Repurchase Date, then, unless otherwise agreed in
writing with the Issuer, promptly after the second Business Day following the Change in Control
Repurchase Date or Optional Repurchase Date, as the case may be, the Paying Agent shall return any
such excess to the Issuer.

ARTICLE 4

Particular Covenants of the Issuer

Section 4.01. Payment of Principal, Premium and Interest. The Issuer covenants and agrees that it
will duly and punctually pay or cause to be paid when due the principal of (including the
redemption price upon redemption or the Optional Repurchase Price or Change in Control Purchase
Price upon repurchase, in each case pursuant to Article 3), and interest on, each of the Notes at
the places, at the respective times and in the manner provided herein and in the Notes.

Section 4.02. Maintenance of Office or Agency. The Issuer will maintain an office or agency where
the Notes may be surrendered for registration of transfer or exchange or for presentation for
payment or for conversion, redemption or repurchase and where notices and demands to or upon the
Issuer in respect of the Notes and this Indenture may be served. As of the date of this Indenture,
such office shall be Sixth Street and Marquette Avenue, MAC N9303-120, Minneapolis, Minnesota
55479, and, at any other time, at such other address as the Trustee may designate from time to time
by notice to the Issuer. The Issuer will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency not designated or appointed by
the Trustee. If at any time the Issuer 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.

The Issuer may also from time to time designate co-registrars and one or more offices or
agencies where the Notes may be presented or surrendered for any or all such purposes and may from
time to time rescind such designations. The Issuer will give prompt written notice to the Trustee
of any such designation or rescission and of any change in the location of any such other office or
agency.

The Issuer hereby initially designates the Trustee as Paying Agent, Note Registrar, Custodian
and Conversion Agent and the Corporate Trust Office shall be considered as one such office or
agency of the Issuer for each of the aforesaid purposes.

So long as the Trustee is the Note Registrar, the Trustee agrees to mail, or cause to be
mailed, the notices set forth in Section 7.10(a) and the third paragraph of Section 7.11. If
co-registrars have been appointed in accordance with this Section, the Trustee shall mail such
notices only to the Issuer and the holders of Notes it can identify from its records.

Section 4.03. Appointments to Fill Vacancies in Trustee’s Office. The Issuer, whenever necessary
to avoid or fill a vacancy in the office of Trustee, will appoint, upon the terms and conditions
and otherwise as provided in Section 7.10, a Trustee, so that there shall at all times be a Trustee
hereunder.

Section 4.04. Provisions as to Paying Agent.

(a) If the Issuer shall appoint a Paying Agent other than the Trustee, or if the Trustee shall
appoint such a Paying Agent, the Issuer will cause such Paying Agent to execute and deliver to the
Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions
of this Section 4.04:

(1) that it will hold all sums held by it as such agent for the payment of the principal of,
or interest on, the Notes (whether such sums have been paid to it by the Issuer or by any other
obligor on the Notes) in trust for the benefit of the holders of the Notes;

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

(3) that at any time during the continuance of an Event of Default, upon request of the
Trustee, it will forthwith pay to the Trustee all sums so held in trust.

The Issuer shall, on or before each due date of the principal of, or interest on, the Notes,
deposit with the Paying Agent a sum (in funds which are immediately available on the due date for
such payment) sufficient to pay such principal, or interest and (unless such Paying Agent is the
Trustee) the Issuer will promptly notify the Trustee of any failure to take such action; provided
that if such deposit is made on the due date, such deposit shall be received by the Paying Agent by
11:00 a.m. New York City time, on such date.

(b) If the Issuer shall act as its own Paying Agent, it will, on or before each due date of
the principal of, or interest on, the Notes, set aside, segregate and hold in trust for the benefit
of the holders of the Notes a sum sufficient to pay such principal and interest so becoming due and
will promptly notify the Trustee of any failure to take such action and of any failure by the
Issuer (or any other obligor under the Notes) to make any payment of the principal of, or interest
on, the Notes when the same shall become due and payable.

(c) Anything in this Section 4.04 to the contrary notwithstanding, the Issuer may, at any
time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other
reason, pay or cause to be paid to the Trustee all sums held in trust by the Issuer or any Paying
Agent hereunder as required by this Section 4.04, such sums to be held by the Trustee upon the
trusts herein contained and upon such payment by the Issuer or any Paying Agent to the Trustee, the
Issuer or such Paying Agent shall be released from all further liability with respect to such sums.

(d) Anything in this Section 4.04 to the contrary notwithstanding, the agreement to hold sums
in trust as provided in this Section 4.04 is subject to Section 11.02 and Section 11.03.

The Trustee shall not be responsible for the actions of any other Paying Agents (including the
Issuer if acting as its own Paying Agent) and shall have no control of any funds held by such other
Paying Agents.

Section 4.05. Existence. Subject to Article 10, the Issuer will do or cause to be done all things
necessary to preserve and keep in full force and effect its existence and rights (charter and
statutory); provided that the Issuer shall not be required to preserve any such right if the Issuer
shall determine that the preservation thereof is no longer desirable in the conduct of its business
and that the loss thereof is not disadvantageous in any material respect to the Noteholders.

Section 4.06. Rule 144A Information Requirement.. Within the period prior to the expiration of the
holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any
successor provision), each of the Issuer and the Guarantors covenants and agrees that it shall,
during any period in which it is not subject to Section 13 or 15(d) under the Exchange Act, make
available to any holder or beneficial holder of Notes or any Common Shares issued upon conversion
thereof which continue to be Restricted Securities in connection with any sale thereof and any
prospective purchaser of Notes or such Common Shares designated by such holder or beneficial
holder, the information required pursuant to Rule 144A(d)(4) under the Securities Act upon the
request of any holder or beneficial holder of the Notes or such Common Shares, all to the extent
required to enable such holder or beneficial holder to sell its Notes or Common Shares without
registration under the Securities Act within the limitation of the exemption provided by Rule 144A.

Section 4.07. Stay, Extension and Usury Laws. The Issuer covenants (to the extent that it may
lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay, extension or usury law or other law which would
prohibit or forgive the Issuer from paying all or any portion of the principal, premium, if any, or
interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in
force, or which may affect the covenants or the performance of this Indenture and the Issuer (to
the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law,
and covenants that it will not, by resort to any such law, 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 4.08. Compliance Certificate. The Issuer shall deliver to the Trustee, within one hundred
twenty (120) calendar days after the end of each fiscal year of the Issuer, a certificate signed by
any of the principal executive officer, principal financial officer or principal accounting officer
of the Issuer, stating whether or not to the knowledge of the signer thereof the Issuer is in
default in the performance and observance of any of the terms, provisions and conditions of this
Indenture (without regard to any period of grace or requirement of notice provided hereunder) and,
if the Issuer shall be in default, specifying all such defaults and the nature and the status
thereof of which the signer may have knowledge.

The Issuer will deliver to the Trustee, promptly upon becoming aware of (i) any default in the
performance or observance of any covenant, agreement or condition contained in this Indenture, or
(ii) any Event of Default, an Officers’ Certificate specifying with particularity such default or
Event of Default and further stating what action the Issuer has taken, is taking or proposes to
take with respect thereto.

Any notice required to be given under this Section 4.08 shall be delivered to a Responsible
Officer of the Trustee at its Corporate Trust Office.

Section 4.09. Additional or Special Interest Notice. In the event that the Issuer is required to
pay Additional Interest pursuant to the Registration Rights Agreement or Special Interest pursuant
to Section 6.01 of this Indenture, to holders of Notes, the Issuer will provide written notice
(“Additional or Special Interest Notice”) to the Trustee of its obligation to pay Additional
Interest or Special Interest no later than fifteen (15) calendar days prior to the proposed payment
date for Additional Interest or Special Interest, and the Additional or Special Interest Notice
shall set forth the amount of Additional Interest or Special Interest to be paid by the Issuer on
such payment date. The Trustee shall not at any time be under any duty or responsibility to any
holder of Notes to determine the Additional Interest or Special Interest, or with respect to the
nature, extent or calculation of the amount of Additional Interest or Special Interest when made,
or with respect to the method employed in such calculation of the Additional Interest or Special
Interest.

ARTICLE 5

Noteholders’ Lists and Reports by the Issuer and the Trustee

Section 5.01. Noteholders’ Lists. The Issuer covenants and agrees that it will furnish or cause to
be furnished to the Trustee, semi-annually, not more than fifteen (15) calendar days after each
April 1 and October 1 in each year beginning with October 1, 2007, and at such other times as the
Trustee may reasonably request in writing, within thirty (30) calendar days after receipt by the
Issuer of any such request (or such lesser time as the Trustee may reasonably request in order to
enable it to timely provide any notice to be provided by it hereunder), a list in such form as the
Trustee may reasonably require of the names and addresses of the holders of Notes as of a date not
more than fifteen (15) calendar days (or such other date as the Trustee may reasonably request in
order to so provide any such notices) prior to the time such information is furnished, except that
no such list need be furnished by the Issuer to the Trustee so long as the Trustee is acting as the
sole Note Registrar.

Section 5.02. Preservation and Disclosure of Lists.

(a) The Trustee shall preserve, in as current a form as is reasonably practicable, all
information as to the names and addresses of the holders of Notes contained in the most recent list
furnished to it as provided in Section 5.01 or maintained by the Trustee in its capacity as Note
Registrar or co-registrar in respect of the Notes, if so acting. The Trustee may destroy any list
furnished to it as provided in Section 5.01 upon receipt of a new list so furnished.

(b) The rights of Noteholders to communicate with other holders of Notes with respect to their
rights under this Indenture or under the Notes, and the corresponding rights and duties of the
Trustee, shall be as provided by the Trust Indenture Act.

(c) Every Noteholder agrees with the Issuer and the Trustee that neither the Issuer nor the
Trustee nor any agent of either of them shall be held accountable by reason of any disclosure of
information as to names and addresses of holders of Notes made pursuant to the Trust Indenture Act.

Section 5.03. Reports by Trustee.

(a) Within sixty (60) calendar days after January 15 of each year commencing with the year
2008, the Trustee shall transmit to holders of Notes such reports dated as of May 15 of the year in
which such reports are made concerning the Trustee and its actions under this Indenture as may be
required pursuant to Section 313(a) of the Trust Indenture Act at the times and in the manner
provided pursuant thereto. In the event that no events have occurred under the applicable sections
of the Trust Indenture Act the Trustee shall be under no duty or obligation to provide such
reports.

(b) A copy of such report shall, at the time of such transmission to holders of Notes, be
filed by the Trustee with each stock exchange and automated quotation system, if any, upon which
the Notes are listed and with the Issuer. The Issuer will promptly notify the Trustee in writing
if the Notes are listed on any stock exchange or automated quotation system or delisted therefrom.

Section 5.04. Reports by Issuer and the Guarantors. The Issuer will file with the Trustee within
15 days after the Issuer files the same with the Commission, copies of the annual reports and of
the information, documents and other reports (or copies of such portions of any of the foregoing as
the Commission may prescribe) which the Issuer is required to file with the Commission pursuant to
Section 13 or Section 15(d) of the Exchange Act. If the Issuer is not required to file
information, documents or reports pursuant to either of those sections, then it will file with the
Trustee and the Commission such reports as may be prescribed by the Commission at such time. The
Issuer shall also file with the Trustee and with the Commission such information, documents and
other reports, and such summaries thereof, as may be required pursuant to the Trust Indenture Act
at the times and in the manner provided by such Act. Delivery of such reports, information and
documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall
not constitute constructive notice of any information contained therein or determinable from
information contained therein, including the Issuer’s and the Guarantors’ compliance with any of
their respective covenants hereunder (as to which the Trustee is entitled to rely exclusively on an
Officers’ Certificate).

ARTICLE 6

Remedies of the Trustee and Noteholders on an Event of Default

Section 6.01. Events of Default. “Event of Default,” wherever used herein, means any one of the
following events (whatever the reason for such Event of Default and whether it shall be voluntary
or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of
any court or any order, rule or regulation of any administrative or governmental body):

(a) default in the payment of any principal amount or any redemption price or Change in
Control Purchase Price due with respect to the Notes when the same shall be due and payable,
whether at maturity, upon redemption or repurchase, by acceleration or otherwise; or

(b) default in the payment of interest (including Additional Interest or Special Interest, if
any) under the Notes as and when the same shall be due and payable, and continuance of such default
for a period of thirty (30) calendar days; or

(c) default in the delivery when due of the amounts owing upon conversion, and the
continuation of such default for 10 days, whether due in cash or the Issuer’s Common Shares, on the

with Article 13 and continuance of such default for five (5) calendar days; or

(d) failure by the Issuer to provide an Issuer Notice after the occurrence of a Change in
Control within the time period required by Section 3.05; or

(e) failure on the part of the Issuer to comply with any other term, covenant or agreement in
the Notes or in this Indenture (other than a covenant or agreement a default in whose performance
or whose breach is elsewhere in this Section 6.01 specifically dealt with) and such failure
continues for a period of sixty (60) calendar days after the date on which written notice of such
failure, requiring the Issuer to remedy the same, shall have been given to the Issuer by the
Trustee, or to the Issuer and a Responsible Officer of the Trustee by the holders of not less than
twenty-five percent (25%) in aggregate principal amount of the Notes at the time outstanding; or

(f) default in the payment of principal when due, or resulting in acceleration of, other
indebtedness of the Issuer or any Significant Subsidiary of the Issuer for borrowed money where the
aggregate principal amount with respect to which the default or acceleration has occurred exceeds
$25.0 million and such indebtedness has not been discharged, or such default in payment or
acceleration has not been cured or rescinded, prior to written notice of such failure to the Issuer
by the Trustee or to the Issuer and the Trustee by holders of not less than ten percent (10%) in
aggregate principal amount of the Notes outstanding; or

(g) any Guarantee by a Significant Subsidiary shall for any reason cease to be, or shall for
any reason be asserted in writing by any Guarantor or the Issuer not to be, in full force and
effect and enforceable in accordance with its terms, except to the extent contemplated by this
Indenture and any such Guarantee; or

(h) failure by the Issuer or any of its Subsidiaries to pay final judgments entered by a court
or courts of competent jurisdiction aggregating in excess of $25.0 million, which judgments are not
paid, discharged or stayed for a period of thirty (30) calendar days after such judgments become
final and non-appealable; or

(i) the Issuer or any Significant Subsidiary of the Issuer pursuant to or under or within
meaning of any Bankruptcy Law:

(i) commences a voluntary case or proceeding seeking liquidation, reorganization or
other relief with respect to it or its debts or seeking the appointment of a trustee,
receiver, liquidator, custodian or other similar official of it or any substantial part of
its property; or

(ii) consents to any such relief or to the appointment of or taking possession by any
such official in an involuntary case or other proceeding commenced against it; or

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

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

(j) an involuntary case or other proceeding shall be commenced against the Issuer or any
Significant Subsidiary of the Issuer seeking liquidation, reorganization or other relief with
respect to it or its debts under any bankruptcy, insolvency or other similar law now or hereafter
in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar
official of it or any substantial part of its property, and such involuntary case or other
proceeding shall remain undismissed and unstayed for a period of sixty (60) calendar days; or

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

(1) is for relief against the Issuer or any Significant Subsidiary of the Issuer in an
involuntary case or proceeding; or

(2) appoints a trustee, receiver, liquidator, custodian or other similar official of the
Issuer or any Significant Subsidiary of the Issuer or any substantial part of their respective
properties; or

(3) orders the liquidation of the Issuer or any Significant Subsidiary of the Issuer;

and, in each case in this clause (j), the order or decree remains unstayed and in effect for sixty
(60) calendar days.

If an Event of Default (other than an Event of Default specified in Section 6.01(i), 6.01(j)
and 6.01(k)) with respect to the Issuer) shall occur and be continuing, unless the principal of all
of the Notes shall have already become due and payable, either the Trustee or the holders of at
least twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding, by
notice in writing to the Issuer (and to the Trustee if given by Noteholders), may declare the
principal of, and interest (including Additional Interest and Special Interest, if any) accrued and
unpaid on, all the Notes to be immediately due and payable, and upon any such declaration the same
shall be immediately due and payable. If an Event of Default specified in Section 6.01(i), 6.01(j)
or 6.01(k) occurs with respect to the Issuer, the principal of, and interest (including Additional
Interest and Special Interest, if any) accrued and unpaid on, all the Notes shall be immediately
and automatically due and payable without necessity of further action.

Notwithstanding the preceding paragraph, to the extent elected by the Issuer, the sole remedy
for an Event of Default relating to the failure to comply with the reporting obligations under
Section 5.04 of this Indenture or for any failure to comply with the requirements of
Section 314(a)(1) of the Trust Indenture Act, will for the first 365 days after the occurrence of
such an Event of Default consist exclusively of the right to receive special interest (“Special
Interest”) on the Notes at an annual rate equal to 0.50% of the principal amount of the Notes. This
Special Interest shall be payable semi-annually in arrears, with the first semi-annual payment due
on the first Interest Payment Date following the date on which such Special Interest shall have
begun to accrue on the Notes. Special Interest shall accrue on all outstanding Notes from and
including the date on which an Event of Default relating to a failure to comply with the reporting
obligations in Section 5.04 of this Indenture or the requirements of Section 314(a)(1) of the
Trust Indenture Act first occurs to but not including the 365th day thereafter (or such earlier
date on which such Event of Default shall have been cured or waived). On such 365th day (or
earlier, if such Event of Default is cured or waived prior to such 365th day), such Special
Interest shall cease to accrue and, if the Event of Default relating to reporting obligations has
not been cured or waived prior to such 365th day, the Notes shall be subject to acceleration as
provided in the immediately preceding paragraph. The provisions of the Indenture described in this
paragraph shall not affect the rights of holders in the event of the occurrence of any other Event
of Default. In the event the Issuer does not elect to pay Special Interest upon an Event of Default
in accordance with this paragraph, the Notes shall be subject to acceleration as provided in the
immediately preceding paragraph.

If the Issuer elects to pay Special Interest in connection with an Event of Default relating
to the failure to comply with the reporting obligations under Section 5.04 of this Indenture or for
any failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act in
accordance with the immediately preceding paragraph, the Issuer shall notify all holders of Notes
and the Trustee and Paying Agent of such election on or before the close of business on the date on
which such Event of Default first occurs.

If, at any time after the principal of and interest on the Notes shall have been so declared
due and payable, and before any judgment or decree for the payment of the monies due shall have
been obtained or entered as hereinafter provided, holders of a majority in aggregate principal
amount of the Notes then outstanding on behalf of the holders of all of the Notes then outstanding,
by written notice to the Issuer and to the Trustee, may waive all defaults or Events of Default and
rescind and annul such declaration and its consequences subject to Section 6.07 if: (a) such
rescission would not conflict with any judgment or decree of a court of competent jurisdiction; (b)
interest on overdue installments of interest (including Additional Interest, if any) (to the extent
that payment of such interest is lawful) and on overdue principal, which has become due otherwise
than by such declaration of acceleration, has been paid; (c) the Issuer has paid the Trustee its
reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances
pursuant to Section 7.06; and (d) all Events of Default, other than the nonpayment of the principal
amount and any accrued and unpaid interest that has become due solely because of such acceleration,
have been cured or waived. No such rescission and annulment shall extend to or shall affect any
subsequent default or Event of Default, or shall impair any right consequent thereon. The Issuer
shall notify in writing a Responsible Officer of the Trustee, promptly upon becoming aware thereof,
of any Event of Default, as provided in Section 4.08.

In case the Trustee shall have proceeded to enforce any right under this Indenture and such
proceedings shall have been discontinued or abandoned because of such waiver or rescission and
annulment or for any other reason or shall have been determined adversely to the Trustee, then and
in every such case the Issuer, the holders of Notes, and the Trustee shall be restored respectively
to their several positions and rights hereunder, and all rights, remedies and powers of the Issuer,
the holders of Notes, and the Trustee shall continue as though no such proceeding had been taken.

Section 6.02. Payments of Notes on Default; Suit Therefor. The Issuer covenants that in the case
of an Event of Default pursuant to Section 6.01(a) or 6.01(b), upon demand of the Trustee, the
Issuer will pay to the Trustee, for the benefit of the holders of the Notes, (i) the whole amount
that then shall be due and payable on all such Notes for principal or interest, as the case may be,
with interest upon the overdue principal and premium, if any, and (to the extent that payment of
such interest is enforceable under applicable law) upon the overdue installments of accrued and
unpaid interest at the rate borne by the Notes, plus 1%, from the required payment date and, (ii)
in addition thereto, any amounts due the Trustee under Section 7.06. Until such demand by the
Trustee, the Issuer may pay the principal of and interest on the Notes to the registered holders,
whether or not the Notes are overdue.

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

In case there shall be pending proceedings for the bankruptcy or for the reorganization of the
Issuer or any other obligor on the Notes under any Bankruptcy Law, or any other applicable law, or
in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator
or similar official shall have been appointed for or taken possession of the Issuer or such other
obligor, the property of the Issuer or such other obligor, or in the case of any other judicial
proceedings relative to the Issuer or such other obligor upon the Notes, or to the creditors or
property of the Issuer or such other obligor, the Trustee, irrespective of whether the principal of
the Notes shall then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this
Section 6.02, shall be entitled and empowered, by intervention in such proceedings or otherwise, to
file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest
in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and
other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee and of the Noteholders allowed in such judicial proceedings relative to the Issuer or any
other obligor on the Notes, its or their creditors, or its or their property, and to collect and
receive any monies or other property payable or deliverable on any such claims, and to distribute
the same after the deduction of any amounts due the Trustee under Section 7.06, and to take any
other action with respect to such claims, including participating as a member of any official
committee of creditors, as it reasonably deems necessary or advisable, unless prohibited by law or
applicable regulations, and any receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, custodian or similar official is hereby authorized by each of the Noteholders 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 Noteholders, to pay to the Trustee any amount due it for reasonable
compensation, expenses, advances and disbursements, including counsel fees and expenses incurred by
it up to the date of such distribution. To the extent that such payment of reasonable
compensation, expenses, advances and disbursements out of the estate in any such proceedings shall
be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out
of, any and all distributions, dividends, monies, securities and other property which the holders
of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any
plan of reorganization or arrangement or otherwise.

All rights of action and of asserting claims under this Indenture, or under any of the Notes,
may be enforced by the Trustee without the possession of any of the Notes, or the production
thereof at any trial or other proceeding relative thereto, and any such suit or proceeding
instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable
benefit of the holders of the Notes.

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation
of any provision of this Indenture to which the Trustee shall be a party), the Trustee shall be
held to represent all the holders of the Notes, and it shall not be necessary to make any holders
of the Notes parties to any such proceedings.

Section 6.03. Application of Monies Collected by Trustee. Any monies or properties collected by
the Trustee pursuant to this Article 6, shall be applied, in the following order, at the date or
dates fixed by the Trustee for the distribution of such monies or properties, upon presentation of
the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender
thereof, if fully paid:

FIRST: To the payment of all amounts due the Trustee under Section 7.06;

SECOND: In case the principal of the outstanding Notes shall not have become due and be
unpaid, to the payment of accrued and unpaid interest, if any, on the Notes in default in the order
of the maturity of the installments of such interest, with interest (to the extent that such
interest has been collected by the Trustee) as provided in Section 6.02 upon the overdue
installments of interest at the annual rate borne by the Notes plus 1%, such payments to be made
ratably to the Persons entitled thereto;

THIRD: In case the principal of the outstanding Notes shall have become due, by declaration
or otherwise, and be unpaid to the payment of the whole amount then owing and unpaid upon the Notes
for principal and interest, with interest on the overdue principal and (to the extent that such
interest has been collected by the Trustee) upon overdue installments of accrued and unpaid
interest, as provided in Section 6.02, and in case such monies shall be insufficient to pay in full
the whole amounts so due and unpaid upon the Notes, then to the payment of such principal and
interest without preference or priority of principal over interest, or of interest over principal,
or of any installment of interest over any other installment of interest, or of any Note over any
other Note, ratably to the aggregate of such principal and accrued and unpaid interest; and

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

Section 6.04. Proceedings by Noteholder. No holder of any Note shall have any right by virtue of
or by reference to any provision of this Indenture to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Indenture, or for the appointment of a
receiver, trustee, liquidator, custodian or other similar official, or for any other remedy
hereunder, except in the case of a default in the payment of principal of, or interest on, the
Notes, unless (a) such holder previously shall have given to the Trustee written notice of an Event
of Default and of the continuance thereof, as hereinbefore provided, (b) the holders of at least
twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding shall have
made written request upon the Trustee to institute such action, suit or proceeding in its own name
as Trustee hereunder and shall have offered to the Trustee satisfactory security or indemnity as it
may require against the costs, liabilities or expenses to be incurred therein or thereby, (c) the
Trustee for sixty (60) calendar days after its receipt of such notice, request and offer of
indemnity, shall have neglected or refused to institute any such action, suit or proceeding and (d)
no direction inconsistent with such written request shall have been given to the Trustee pursuant
to Section 6.07; it being understood and intended, and being expressly covenanted by the taker and
holder of every Note with every other taker and holder and the Trustee, that no one or more holders
of Notes shall have any right in any manner whatever by virtue of or by reference to any provision
of this Indenture to affect, disturb or prejudice the rights of any other holder of Notes, or to
obtain or seek to obtain priority over or preference to any other such holder, or to enforce any
right under this Indenture, except in the manner herein provided and for the equal, ratable and
common benefit of all holders of Notes (except as may otherwise be provided herein). For the
protection and enforcement of this Section 6.04, each and every Noteholder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

Notwithstanding any other provision of this Indenture and any provision of any Note, the right
of any holder of any Note to receive payment of the principal of (including the redemption price or
Change in Control Purchase Price upon redemption or repurchase pursuant to Article 3) and accrued
interest on such Note, on or after the respective due dates expressed in such Note or in the event
of redemption or repurchase, or to institute suit for the enforcement of any such payment on or
after such respective dates against the Issuer shall not be impaired or affected without the
consent of such holder.

Anything contained in this Indenture or the Notes to the contrary notwithstanding, the holder
of any Note, without the consent of either the Trustee or the holder of any other Note, in its own
behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable
to enforce, its rights of conversion as provided herein.

Section 6.05. Proceedings by Trustee. In case of an Event of Default, the Trustee may, in its
discretion, proceed to protect and enforce the rights vested in it by this Indenture by such
appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either
by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the
specific enforcement of any covenant or agreement contained in this Indenture or any Guarantee or
in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

Section 6.06. Remedies Cumulative and Continuing. All powers and remedies given by this Article 6
to the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative
and not exclusive of any thereof or of any other powers and remedies available to the Trustee or
the holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or
observance of the covenants and agreements contained in this Indenture, and no delay or omission of
the Trustee or of any holder of any of the Notes to exercise any right or power accruing upon any
default or Event of Default occurring and continuing as aforesaid shall impair any such right or
power, or shall be construed to be a waiver of any such default or any acquiescence therein, and,
subject to the provisions of Section 6.04, every power and remedy given by this Article 6 or by law
to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be
deemed expedient, by the Trustee or by the Noteholders.

Section 6.07. Direction of Proceedings and Waiver of Defaults by Majority of Noteholders. The
holders of not less than a majority in aggregate principal amount of the Notes at the time
outstanding shall have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee;
provided that (a) such direction shall not be in conflict with any rule of law or with this
Indenture, (b) the Trustee may take any other action which is not inconsistent with such direction,
(c) the Trustee may decline to take any action that would benefit some Noteholder to the detriment
of other Noteholders and (d) the Trustee may decline to take any action that would involve the
Trustee in personal liability.

The holders of a majority in aggregate principal amount of the Notes at the time outstanding
may, on behalf of the holders of all of the Notes, waive any past default or Event of Default
hereunder and its consequences except (i) a default in the payment of the principal of, or
interest (including Additional Interest, if any) on, the Notes, (ii) a failure by the Issuer to
convert any Notes as required by this Indenture, (iii) a default in the payment of the redemption
price on the Redemption Date pursuant to Article 3, (iv) a default in the payment of the Change in
Control Purchase Price or the Optional Repurchase Price on the Change in Control Repurchase Date or
an Optional Repurchase Date, as the case may be, pursuant to Article 3 or (v) a default in respect
of a covenant or provisions hereof which under Article 9 cannot be modified or amended without the
consent of the holders of all Notes then outstanding or each Note affected thereby.

Upon any such waiver, the Issuer, the Trustee and the holders of the Notes shall be restored
to their former positions and rights hereunder; but no such waiver shall extend to any subsequent
or other default or Event of Default or impair any right consequent thereon. Whenever any default
or Event of Default hereunder shall have been waived as permitted by this Section 6.07, said
default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to
have been cured and to be not continuing; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

Section 6.08. Notice of Defaults. The Trustee shall, within ninety (90) calendar days after a
Responsible Officer of the Trustee has knowledge of the occurrence of a default or Event of
Default, mail to all Noteholders, as the names and addresses of such holders appear upon the Note
Register, notice of all defaults or Events of Default known to a Responsible Officer, unless such
defaults or Events of Default shall have been cured or waived before the giving of such notice;
provided that except in the case of default in the payment of the principal of, or interest
(including Additional Interest, if any) on, any of the Notes, the Trustee shall be protected in
withholding such notice if and so long as a committee of Responsible Officers or a Responsible
Officer of the Trustee in good faith determines that the withholding of such notice is in the
interest of the Noteholders.

Section 6.09. Undertaking to Pay Costs. All parties to this Indenture agree, and each holder of
any Note by its 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 an undertaking to pay the costs of such suit and that such court
may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses,
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; provided that the provisions of this Section 6.09
(to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit
instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than ten
percent in principal amount of the Notes at the time outstanding determined in accordance with
Section 8.04, or to any suit instituted by any Noteholder for the enforcement of the payment of the
principal of, or interest on, any Note on or after the due date expressed in such Note or to any
suit for the enforcement of the right to convert any Note in accordance with the provisions of
Article 13.

ARTICLE 7

The Trustee

Section 7.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an
Event of Default and after the curing or waiver of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set forth in this
Indenture. In case an Event of Default has occurred (which has not been cured or waived), the
Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the
same degree of care and skill in their exercise, as a prudent person would exercise or use under
the circumstances in the conduct of its own affairs.

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

(a) prior to the occurrence of an Event of Default and after the curing or waiving of all
Events of Default which may have occurred:

(i) the duties and obligations of the Trustee shall be determined solely by the express
provisions of this Indenture and the Trust Indenture Act, and the Trustee shall not be
liable except for the performance of such duties and obligations as are specifically set
forth in this Indenture and no implied covenants or obligations shall be read into this
Indenture and the Trust Indenture Act against the Trustee; and

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

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

(c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by
it in good faith in accordance with the written direction of the holders of not less than a
majority in principal amount of the Notes at the time outstanding determined as provided in Section
8.04 relating to the time, method and place of conducting any proceeding for any remedy available
to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture;

(d) whether or not therein provided, every provision of this Indenture relating to the conduct
or affecting the liability of, or affording protection to, the Trustee shall be subject to the
provisions of this Section;

(e) the Trustee shall not be liable in respect of any payment (as to the correctness of
amount, entitlement to receive or any other matters relating to payment) or notice effected by the
Issuer or any Paying Agent (other than the Trustee) or any records maintained by any co-registrar
(other than the Trustee) with respect to the Notes;

(f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to
this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its
failure to receive such notice as reason to act as if no such event occurred unless a Responsible
Officer of the Trustee has actual knowledge thereof or unless the Trustee has otherwise received
written notice thereof; and

(g) the Trustee shall not be deemed to have knowledge of any Event of Default hereunder unless
a Responsible Officer of the Trustee has actual knowledge thereof or unless the Trustee shall have
been notified in writing of such Event of Default by the Issuer or a holder of Notes.

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

Section 7.02. Reliance on Documents, Opinions, etc. Except as otherwise provided in Section 7.01:

(a) the Trustee may conclusively rely and shall be protected in acting upon any resolution,
certificate, statement, instrument, opinion, report, notice, request, consent, order, bond,
debenture, note, coupon or other paper or document (whether in its original or facsimile form)
believed by it in good faith to be genuine and to have been signed or presented by the proper party
or parties;

(b) any request, direction, order or demand of the Issuer mentioned herein shall be
sufficiently evidenced by an Officers’ Certificate (unless other evidence in respect thereof be
herein specifically prescribed); and any resolution of the Board of Trustees may be evidenced to
the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Issuer;

(c) the Trustee may consult with counsel of its own selection and any advice or Opinion of
Counsel shall be full and complete authorization and protection in respect of any action taken or
omitted by it hereunder in good faith and in reliance on and in accordance with such advice or
Opinion of Counsel;

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

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

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

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

(h) the rights, privileges, protections, immunities and benefits given to the Trustee,
including, without limitation, its right to be indemnified, are extended to, and shall be
enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and
other Person employed to act hereunder;

(i) the Trustee may request that the Issuer deliver an Officers’ Certificate setting forth the
names of individuals and/or titles of officers authorized at such time to take specified actions
pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to
sign an Officers’ Certificate, including any person specified as so authorized in any such
certificate previously delivered and not superseded; and

(j) any permissive right or authority granted to the Trustee shall not be construed as a
mandatory duty.

Section 7.03. No Responsibility for Recitals, etc. The recitals contained herein and in the Notes
(except in the Trustee’s certificate of authentication) shall be taken as the statements of the
Issuer, and the Trustee assumes no responsibility for the correctness of the same. The Trustee
makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The
Trustee shall not be accountable for the use or application by the Issuer of any Notes or the
proceeds of any Notes authenticated and delivered by the Trustee in conformity with the provisions
of this Indenture.

Section 7.04. Trustee, Paying Agents, Conversion Agents or Note Registrar May Own Notes. The
Trustee, any Paying Agent, the Conversion Agent or Note Registrar, in its individual or any other
capacity, may become the owner or pledgee of Notes with the same rights it would have if it were
not Trustee, Paying Agent, Conversion Agent or Note Registrar.

Section 7.05. Monies to be Held in Trust. Subject to the provisions of Section 11.04, all monies
received by the Trustee shall, until used or applied as herein provided, be held in trust for the
purposes for which they were received. Money held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law. Except as otherwise provided
herein, the Trustee shall be under no liability for interest on any money received by it hereunder
except as may be agreed in writing from time to time by the Issuer and the Trustee.

Section 7.06. Compensation and Expenses of Trustee. The Issuer covenants and agrees to pay to the
Trustee from time to time, and the Trustee shall be entitled to, such compensation for all services
rendered by it hereunder in any capacity (which shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust) as mutually agreed to from time to
time in writing between the Issuer and the Trustee, and the Issuer will pay or reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances reasonably
incurred or made by the Trustee in accordance with any of the provisions of this Indenture
(including the reasonable compensation and the reasonable expenses and disbursements of its counsel
and of all Persons not regularly in its employ) except any such expense, disbursement or advance as
may arise from its negligence, willful misconduct, recklessness or bad faith. The Issuer also
covenants to indemnify the Trustee and any predecessor Trustee (or any officer, director or
employee of the Trustee), in any capacity under this Indenture and any authenticating agent for,
and to hold them harmless against, any and all loss, liability, damage, claim or reasonable expense
including taxes (other than taxes based on the income of the Trustee) incurred without negligence,
willful misconduct, recklessness or bad faith on the part of the Trustee or such officers,
directors, employees or authenticating agent, as the case may be, and arising out of or in
connection with the acceptance or administration of this trust or in any other capacity hereunder,
including the reasonable costs and expenses of defending themselves against any claim (whether
asserted by the Issuer, any holder or any other Person) of liability in the premises. The
obligations of the Issuer under this Section 7.06 to compensate or indemnify the Trustee and to pay
or reimburse the Trustee for reasonable expenses, disbursements and advances shall be secured by a
lien prior to that of the Notes upon all property and funds held or collected by the Trustee as
such, except funds held in trust for the benefit of the holders of particular Notes in connection
with a redemption or repurchase of Notes pursuant to Article 3, a satisfaction or discharge of this
Indenture pursuant to Article II or a conversion of Notes pursuant to Article 13. The obligation
of the Issuer under this Section shall survive the satisfaction and discharge of this Indenture.

When the Trustee and its agents and any authenticating agent incur expenses or render services
after an Event of Default specified in Section 6.01(i), 6.01(j) or 6.01(k) with respect to the
Issuer occurs, the expenses and the compensation for the services are intended to constitute
reasonable expenses of administration under any bankruptcy, insolvency or similar laws.

Section 7.07. Officers’ Certificate as Evidence. Except as otherwise provided in Section 7.01,
whenever in the administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or omitting any
action hereunder, such matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of gross negligence, bad faith, recklessness or willful misconduct
on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’
Certificate delivered to the Trustee.

Section 7.08. Conflicting Interests of Trustee. If the Trustee has or shall acquire a conflicting
interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to the provisions of,
the Trust Indenture Act and this Indenture.

Section 7.09. Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall
be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus of at least $50.0 million (or if such Person is a member of a bank holding
company system, its bank holding company shall have a combined capital and surplus of at least
$50.0 million). If such Person publishes reports of condition at least annually, pursuant to law
or to the requirements of any supervising or examining authority, then for the purposes of this
Section the combined capital and surplus of such Person shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this Section 7.09, it shall
resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 7.10. Resignation or Removal of Trustee.

(a) Subject to Section 7.10(c), the Trustee may at any time resign by giving written notice of
such resignation to the Issuer and to the holders of Notes. Upon receiving such notice of
resignation, the Issuer shall promptly appoint a successor trustee by written instrument, in
duplicate, executed by order of the Board of Trustees, one copy of which instrument shall be
delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee
shall have been so appointed and have accepted appointment sixty (60) calendar days after the
mailing of such notice of resignation to the Noteholders, the resigning Trustee may, upon ten
Business Days’ notice to the Issuer and the Noteholders, petition, at the expense of the Issuer,
any court of competent jurisdiction for the appointment of a successor trustee. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor
trustee.

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

(i) the Trustee shall fail to comply with Section 7.08 after written request therefor
by the Issuer or by any Noteholder who has been a bona fide holder of a Note or Notes for at
least six months; or

(ii) the Trustee shall cease to be eligible in accordance with the provisions of
Section 7.09 and shall fail to resign after written request therefor by the Issuer or by any
such Noteholder; or

(iii) 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, the Issuer may remove the Trustee and appoint a successor trustee by
written instrument, in duplicate, executed by order of the Board of Trustees, one copy of which
instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or,
subject to the provisions of Section 6.09, any Noteholder who has been a bona fide holder of a Note
or Notes for at least six months may, on behalf of itself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee and the appointment of
a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper
and prescribe, remove the Trustee and appoint a successor trustee.

(c) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant
to any of the provisions of this Section 7.10 shall become effective upon acceptance of appointment
by the successor trustee as provided in Section 7.11.

(d) Notwithstanding the replacement of the Trustee pursuant to this Section, the Issuer’s
obligations under Section 7.06 shall continue for the benefit of the retiring Trustee.

Section 7.11. Acceptance by Successor Trustee. Any successor trustee appointed as provided in
Section 7.10 shall execute, acknowledge and deliver to the Issuer and to its predecessor trustee an
instrument accepting such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as trustee herein; but,
nevertheless, on the written request of the Issuer or of the successor trustee, the trustee ceasing
to act shall, upon payment of any amount then due it pursuant to the provisions of Section 7.06,
execute and deliver an instrument transferring to such successor trustee all the rights and powers
of the trustee so ceasing to act. Upon request of any such successor trustee, the Issuer shall
execute any and all instruments in writing for more fully and certainly vesting in and confirming
to such successor trustee all such rights and powers. Any trustee ceasing to act shall,
nevertheless, retain a lien upon all property and funds held or collected by such trustee as such,
except for funds held in trust for the benefit of holders of particular Notes, to secure any
amounts then due it pursuant to the provisions of Section 7.06.

No successor trustee shall accept appointment as provided in this Section 7.11 unless, at the
time of such acceptance, such successor trustee shall be qualified under the provisions of Section
7.08 and be eligible under the provisions of Section 7.09.

Upon acceptance of appointment by a successor trustee as provided in this Section 7.11, the
Issuer (or the former trustee, at the written direction of the Issuer) shall mail or cause to be
mailed notice of the succession of such trustee hereunder to the holders of Notes at their
addresses as they shall appear on the Note Register. If the Issuer fails to mail such notice
within ten (10) calendar days after acceptance of appointment by the successor trustee, the
successor trustee shall cause such notice to be mailed at the expense of the Issuer.

Section 7.12. Succession by Merger. Any corporation into which the Trustee may be merged or
exchanged or with which it may be consolidated, or any corporation resulting from any merger,
exchange or consolidation to which the Trustee shall be a party, or any corporation succeeding to
all or substantially all of the corporate trust business of the Trustee (including any trust
created by this Indenture), shall be the successor to the Trustee hereunder without the execution
or filing of any paper or any further act on the part of any of the parties hereto, provided that
in the case of any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, such corporation shall be qualified under the provisions of Section 7.08
and eligible under the provisions of Section 7.09.

In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to
the Trustee may adopt the certificate of authentication of any predecessor trustee or
authenticating agent appointed by such predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been authenticated, any
successor to the Trustee or any authenticating agent appointed by such successor trustee may
authenticate such Notes in the name of the successor trustee; and in all such cases such
certificates shall have the full force that is provided in the Notes or in this Indenture; provided
that the right to adopt the certificate of authentication of any predecessor Trustee or
authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or
successors by merger, exchange or consolidation.

Section 7.13. Preferential Collection of Claims. If and when the Trustee shall be or become a
creditor of the Issuer (or any other obligor upon the Notes), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of the claims against the Issuer (or
any such other obligor).

ARTICLE 8

The Noteholders

Section 8.01. Action by Noteholders. Whenever in this Indenture it is provided that the holders of
a specified percentage in aggregate principal amount of the Notes may take any action (including
the making of any demand or request, the giving of any notice, consent or waiver or the taking of
any other action), the fact that at the time of taking any such action, the holders of such
specified percentage have joined therein may be evidenced (a) by any instrument or any number of
instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in
writing, or (b) by the record of the holders of Notes voting in favor thereof at any meeting of
Noteholders, or (c) by a combination of such instrument or instruments and any such record of such
a meeting of Noteholders. Whenever the Issuer or the Trustee solicits the taking of any action by
the holders of the Notes, the Issuer or the Trustee may fix in advance of such solicitation a date
as the record date for determining holders entitled to take such action. The record date, if any,
shall be not more than fifteen (15) calendar days prior to the date of commencement of solicitation
of such action.

Section 8.02. Proof of Execution by Noteholders. Subject to the provisions of Sections 7.01 and
7.02, proof of the execution of any instrument by a Noteholder or its agent or proxy shall be
sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by
the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall
be proved by the registry of such Notes or by a certificate of the Note Registrar.

Section 8.03. Absolute Owners. The Issuer, the Trustee, any Paying Agent, any Conversion Agent and
any Note Registrar may deem the Person in whose name such Note shall be registered upon the Note
Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note
shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any
Person other than the Issuer or any Note Registrar) for the purpose of receiving payment of or on
account of the principal of, and interest on, such Note, for conversion of such Note and for all
other purposes; and neither the Issuer nor the Trustee nor any Paying Agent nor any Conversion
Agent nor any Note Registrar shall be affected by any notice to the contrary. All such payments so
made to any holder for the time being, or upon its order, shall be valid, and, to the extent of the
sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any
such Note.

Section 8.04. Issuer-Owned Notes Disregarded. In determining whether the holders of the requisite
aggregate principal amount of Notes have concurred in any direction, consent, waiver or other
action under this Indenture, Notes which are owned by the Issuer or any other obligor on the Notes
or any Affiliate of the Issuer or any other obligor on the Notes shall be disregarded and deemed
not to be outstanding for the purpose of any such determination; provided that for the purposes of
determining whether the Trustee shall be protected in relying on any such direction, consent,
waiver or other action, only Notes which a Responsible Officer knows are so owned shall be so
disregarded. Notes so owned which have been pledged in good faith may be regarded as outstanding
for the purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of the
Trustee the pledgee’s right to vote such Notes and that the pledgee is not the Issuer, any other
obligor on the Notes or any Affiliate of the Issuer or any such other obligor. In the case of a
dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be
full protection to the Trustee. Upon request of the Trustee, the Issuer shall furnish to the
Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the
Issuer to be owned or held by or for the account of any of the above described Persons, and,
subject to Section 7.01, the Trustee shall be entitled to accept such Officers’ Certificate as
conclusive evidence of the facts therein set forth and of the fact that all Notes not listed
therein are outstanding for the purpose of any such determination.

Section 8.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not after)
the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the
holders of the percentage in aggregate principal amount of the Notes specified in this Indenture in
connection with such action, any holder of a Note which is shown by the evidence to be included in
the Notes the holders of which have consented to such action may, by filing written notice with the
Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 8.02, revoke
such action so far as concerns such Note. Except as aforesaid, any such action taken by the holder
of any Note shall be conclusive and binding upon such holder and upon all future holders and owners
of such Note and of any Notes issued in exchange or substitution therefor, irrespective of whether
any notation in regard thereto is made upon such Note or any Note issued in exchange or
substitution therefor.

ARTICLE 9

Supplemental Indentures

Section 9.01. Supplemental Indentures Without Consent of Noteholders. The Issuer, when authorized
by the resolutions of the Board of Trustees, and the Trustee may, from time to time, and at any
time enter into an indenture or indentures supplemental without the consent of the holders of the
Notes hereto for one or more of the following purposes:

(a) to evidence a successor to the Issuer or any Guarantor and the assumption by that
successor of the obligations of the Issuer or such Guarantor, as applicable, under this Indenture
and the Notes;

(b) to provide for conversion rights of holders of the Notes if any reclassification or change
of Common Shares or any consolidation, merger or sale of all or substantially all of the property
or assets of the Issuer occurs;

(c) to add to the covenants of the Issuer or any Guarantor for the benefit of the holders of
the Notes or to surrender any right or power conferred upon the Issuer or any Guarantor;

(d) to secure the obligations of the Issuer or any Guarantor in respect of the Notes;

(e) to add guarantees or to release a Guarantor in accordance with the terms of this
Indenture;

(f) to evidence and provide the acceptance of the appointment of a successor Trustee under
this Indenture;

(g) to comply with the requirements of the Commission in order to effect or maintain
qualification of this Indenture under the Trust Indenture Act, as contemplated by this Indenture or
otherwise;

(h) to cure any ambiguity, omission, defect or inconsistency in this Indenture or make any
other provision with respect to matters or questions arising under this Indenture which the Issuer
may deem necessary or desirable and which shall not be inconsistent with provisions of this
Indenture; provided that such modification or amendment does not, in the good faith opinion of the
Board of Trustees, adversely affect the interests of the holders of the Notes in any material
respect;

(i) to add or modify any provision with respect to matters or questions arising under this
Indenture which the Issuer may deem necessary or desirable and which will not adversely affect the
interests of the holders of the Notes in any material respect; or

(j) to modify any provision of this Indenture to conform that provision to the description
thereof set forth in the Offering Memorandum.

Upon the written request of the Issuer, accompanied by a copy of the resolutions of the Board
of Trustees certified by the Issuer’s Secretary or Assistant Secretary authorizing the execution of
any supplemental indenture, the Trustee is hereby authorized to join with the Issuer in the
execution of any such supplemental indenture, to make any further appropriate agreements and
stipulations that may be therein contained and to accept the conveyance, transfer and assignment of
any property thereunder, but the Trustee shall not be obligated to, but may in its discretion,
enter into any supplemental indenture that affects the Trustee’s own rights, duties or immunities
under this Indenture or otherwise.

Any supplemental indenture authorized by the provisions of this Section 9.01 may be executed
by the Issuer and the Trustee without the consent of the holders of any of the Notes at the time
outstanding, notwithstanding any of the provisions of Section 9.02.

Section 9.02. Supplemental Indenture With Consent of Noteholders. With the consent (evidenced as
provided in Article 8) of the holders of not less than a majority in aggregate principal amount of
the Notes at the time outstanding, the Issuer, when authorized by the resolutions of the Board of
Trustees, and the Trustee may, from time to time and at any time, enter into an indenture or
indentures supplemental hereto for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Indenture or any supplemental indenture or
modifying in any manner the rights of the holders of the Notes; provided that no such supplemental
indenture shall, without the consent of the holder of each Note so affected:

(a) impair or adversely affect the manner of calculation or rate of accrual of interest
(including Additional Interest or Special Interest) on the Notes or change the time of payment
thereof;

(b) make the Note payable in money or securities other than that stated in the note;

(c) change the Stated Maturity of the Notes;

(d) reduce the principal amount of, or the redemption price or Change in Control Purchase
Price or Optional Repurchase Price specified in Article 3 hereof with respect to, the Notes;

(e) make any change that impairs or adversely affects the conversion rights of the holders of
the Notes;

(f) make any change that impairs or adversely affects the right to require the Issuer to
repurchase the Notes;

(g) release any Guarantor from any of its obligations under its Guarantee or the Indenture
otherwise than in accordance with the terms of this Indenture;

(h) impair the right to institute suit for the enforcement of any payment with respect to the
Notes or with respect to conversion of the Notes;

(i) change the obligation of the Issuer to redeem any Notes called for redemption on a
Redemption Date in a manner adverse to the holders;

(j) change the obligation of the Issuer to maintain an office or agency pursuant to Section
4.02;

(k) make the Notes subordinate in right of payment to any other indebtedness;

(l) reduce the percentage in aggregate principal amount of outstanding Notes required to
modify or amend this Indenture or to waive compliance by the Issuer or any Guarantor with the
provisions of the Indenture; or

(m) modify Section 6.07 or this Section 9.02.

Upon the written request of the Issuer, accompanied by a copy of the resolutions of the Board
of Trustees certified by the Issuer’s Secretary or Assistant Secretary authorizing the execution of
any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of
Noteholders as aforesaid, the Trustee shall join with the Issuer in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties
or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion,
but shall not be obligated to, enter into such supplemental indenture.

It shall not be necessary for the consent of the Noteholders under this Section 9.02 to
approve the particular form of any proposed supplemental indenture, but it shall be sufficient if
such consent shall approve the substance thereof.

Section 9.03. Effect of Supplemental Indenture. Any supplemental indenture executed pursuant to
the provisions of this Article 9 shall comply with the Trust Indenture Act, as then in effect,
provided that this Section 9.03 shall not require such supplemental indenture or the Trustee to be
qualified under the Trust Indenture Act prior to the time, if ever, such qualification is in fact
required under the terms of the Trust Indenture Act or the Indenture has been qualified under the
Trust Indenture Act, nor shall it constitute any admission or acknowledgment by any party to such
supplemental indenture that any such qualification is required prior to the time, if ever, such
qualification is in fact required under the terms of the Trust Indenture Act or the Indenture has
been qualified under the Trust Indenture Act. Upon the execution of any supplemental indenture
pursuant to the provisions of this Article 9, this Indenture shall be and be deemed to be modified
and amended in accordance therewith and the respective rights, limitation of rights, obligations,
duties and immunities under this Indenture of the Trustee, the Issuer and the holders of Notes
shall thereafter be determined, exercised and enforced hereunder, subject in all respects to such
modifications and amendments and all the terms and conditions of any such supplemental indenture
shall be and be deemed to be part of the terms and conditions of this Indenture for any and all
purposes.

Section 9.04. Notation on Notes. The Trustee may place on the Notes authenticated and delivered
after the execution of any supplemental indenture pursuant to the provisions of this Article 9 may
bear an appropriate notation in form approved by the Trustee as to any matter provided for in such
supplemental indenture. If the Issuer so determines, new Notes so modified as to conform, in the
opinion of the Board of Trustees, to any modification of this Indenture contained in any such
supplemental indenture may, at the Issuer’s expense, be prepared and executed by the Issuer and any
applicable Guarantor, authenticated by the Trustee (or an authenticating agent duly appointed by
the Trustee pursuant to Section 15.11) and delivered in exchange for the Notes then outstanding,
upon surrender of such Notes then outstanding.

Section 9.05. Evidence of Compliance of Supplemental Indenture to be Furnished to Trustee. Prior
to entering into any supplemental indenture pursuant to this Article 9, the Trustee shall be
provided with an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any
supplemental indenture executed pursuant hereto complies with the requirements of this Article 9
and is otherwise authorized or permitted by this Indenture.

ARTICLE 10

Consolidation, Merger, Sale, Conveyance and Lease

Section 10.01. Issuer May Consolidate on Certain Terms. Subject to the provisions of Section
10.02, the Issuer shall not, in a single transaction or a series of related transactions,
consolidate with, or sell, lease or convey all or substantially all of its property and assets to,
or merge with or into, any other Person (whether or not affiliated with the Issuer), unless: (i)
the Issuer is the continuing entity, or the successor (if other than the Issuer) formed by or
resulting from any consolidation or merger or which shall have received the transfer of assets
shall be an entity organized and existing under the laws of the United States of America, any state
thereof or the District of Columbia and shall expressly assume (x) the due and punctual payment of
the principal of, and interest on, all of the Notes, and the due and punctual performance and
observance of all of the covenants and conditions in the Notes and this Indenture to be performed
or satisfied by the Issuer (including, without limitations, the obligation to convert Notes in
accordance with the provisions of Article 13 hereof) by a supplemental indenture reasonably
satisfactory in form to the Trustee and (y) all of the obligations of the Issuer under the
Registration Rights Agreement by a supplemental agreement, in each case, executed and delivered to
the Trustee by such successor; (ii) if as a result of any such consolidation, sale, lease,
conveyance or merger, the Notes become convertible into common shares or other securities issued by
a Person that is other than the Issuer or such successor Person, such Person shall fully and
unconditionally guarantee all obligations under the Notes and this Indenture; (iii) immediately
after giving effect to the transaction described above, no Event of Default or event which, after
notice or lapse of time, or both, would become an Event of Default, has occurred and is continuing;
and (iv) the Issuer has delivered to the Trustee the Officers’ Certificate and Opinion of Counsel,
if any, requested pursuant to Section 15.03.

Section 10.02. Issuer Successor to be Substituted. In case of any such consolidation, sale, lease,
conveyance or merger in which the Issuer is not the continuing entity and upon the assumption by
the successor Person, by supplemental indenture, executed and delivered to the Trustee and
reasonably satisfactory in form to the Trustee, of the due and punctual payment of the principal
of, and interest on, all of the Notes, and the due and punctual performance and observance of all
of the covenants and conditions of this Indenture to be performed or satisfied by the Issuer, and
by supplemental agreement, executed and delivered to the Trustee and reasonably satisfactory in
form to the Trustee, of all of the obligations of the Issuer under the Registration Rights
Agreement, such successor Person shall succeed to and be substituted for the Issuer, with the same
effect as if it had been named herein as the party of this first part, and the Issuer shall be
discharged from its obligations under the Notes, this Indenture and the Registration Rights
Agreement. Such successor Person thereupon may cause to be signed, and may issue either in its own
name or in the name of the Issuer any or all of the Notes, issuable hereunder that theretofore
shall not have been signed by the Issuer and delivered to the Trustee; and, upon the order of such
successor Person instead of the Issuer and subject to all the terms, conditions and limitations in
this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be
authenticated and delivered, any Notes that previously shall have been signed and delivered by the
officers of the Issuer to the Trustee for authentication, and any Notes that such successor Person
thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes
so issued shall in all respects have the same legal rank and benefit under this Indenture as the
Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all
of such Notes had been issued at the date of the execution hereof. In the event of any such
consolidation, merger, sale, conveyance, transfer or lease, upon compliance with this Article 10
the Person named as the “Issuer” in the first paragraph of this Indenture or any successor that
shall thereafter have become such in the manner prescribed in this Article 10 may be dissolved,
wound up and liquidated at any time thereafter and such Person shall be discharged from its
liabilities as obligor and maker of the Notes and from its obligations under this Indenture and
under the Registration Rights Agreement.

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

ARTICLE 11

Satisfaction and Discharge of Indenture

Section 11.01. Discharge of Indenture. This Indenture shall cease to be of further effect (except
as to any surviving rights of conversion, registration of transfer or exchange of Notes herein
expressly provided for and except as further provided below), and the Trustee, on demand of and at
the expense of the Issuer, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when (a) either: (1) all Notes theretofore authenticated and delivered
(other than (i) Notes which have been destroyed, lost or stolen and which have been replaced or
paid as provided in Section 11.04 and (ii) Notes for whose payment money has theretofore been
deposited in trust and thereafter repaid to the Issuer as provided in Section 11.04) have been
delivered to the Trustee for cancellation; or (2) all such Notes not theretofore delivered to the
Trustee for cancellation have become due and payable, whether upon the Stated Maturity of the
Notes, a Redemption Date, an Optional Repurchase Date or a Change in Control Repurchase Date or
otherwise, or have all been converted in accordance with the provisions of Article 13 hereof, and
the Issuer has irrevocably deposited or caused to be irrevocably deposited with the Trustee, a
Paying Agent or the Conversion Agent (other than the Issuer or any of its Affiliates), as
applicable, as trust funds in trust cash and, if applicable, Common Shares in an amount sufficient
to pay and discharge the entire indebtedness on such Notes not theretofore delivered to the Trustee
for cancellation, for principal and interest to the date of such deposit (in the case of Notes
which have become due and payable) or for amounts owing upon conversion; provided, however, that
there shall not exist, on the date of such deposit, a default or Event of Default; provided,
further, that such deposit shall not result in a breach or violation of, or constitute a default
under, this Indenture or any other agreement or instrument to which the Issuer is a party or to
which the Issuer is bound; (b) the Issuer has paid or caused to be paid all other sums payable
hereunder by the Issuer; and (c) the Issuer has delivered to the Trustee an Officers’ Certificate
and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating
to the satisfaction and discharge of this Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the
Issuer to the Trustee under Section 7.06 shall survive and, if money shall have been deposited with
the Trustee pursuant to subclause (2) of clause (a) of this Section, the provisions of Sections
2.05, 2.06, 2.07, 3.05, 3.06, 5.01, Article 13 and this Article 11, shall survive until the Notes
have been paid in full.

Section 11.02. Deposited Monies to be Held in Trust by Trustee. Subject to Section 11.04, all
monies deposited with the Trustee pursuant to Section 11.01, shall be held in trust for the sole
benefit of the Noteholders for the purposes of Section 11.01 (as set forth in set forth in Section
7.05), and such monies shall be applied by the Trustee to the payment, either directly or through
any Paying Agent (including the Issuer if acting as its own Paying Agent), to the holders of the
particular Notes for the payment or redemption of which such monies have been deposited with the
Trustee, of all sums due and to become due thereon for principal, premium, if any, and interest.
The Trustee is not responsible to anyone for interest on any deposited funds except as agreed in
writing.

Section 11.03. Paying Agent to Repay Monies Held. Subject to the provisions of Section 11.04, the
Trustee or a Paying Agent shall hold in trust, for the benefit of the Noteholders, all money
deposited with it pursuant to Section 11.01 and shall apply the deposited money in accordance with
this Indenture and the Notes to the payment of the principal of and interest on the Notes.

Section 11.04. Return of Unclaimed Monies. Subject to all applicable abandoned property law, the
Trustee and each Paying Agent shall pay to the Issuer upon written request any money held by them
for the payment of principal or interest that remains unclaimed for two years after a right to such
money has matured; provided, however, that the Trustee or such Paying Agent, before being required
to make any such payment, may, at the expense of the Issuer, either publish in a newspaper of
general circulation in The City of New York, or cause to be mailed to each holder entitled to such
money, notice that such money remains unclaimed and that after a date specified therein, which
shall be at least thirty (30) calendar days from the date of such mailing or publication, any
unclaimed balance of such money then remaining will be repaid to the Issuer. After payment to the
Issuer, holders entitled to money must look to the Issuer for payment as general creditors unless
an applicable abandoned property law designates another person, and the Trustee and each Paying
Agent shall be relieved of all liability with respect to such money.

Section 11.05. Reinstatement. If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 11.02 by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s
obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit
had occurred pursuant to Section 11.01 until such time as the Trustee or the Paying Agent is
permitted to apply all such money in accordance with Section 11.02; provided that if the Issuer
makes any payment of principal of or premium, if any, or interest on any Note following the
reinstatement of its obligations, the Issuer shall be subrogated to the rights of the holders of
such Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 12

Immunity of Incorporators, Shareholders, Officers, Trustees and Directors

Section 12.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment of
the principal of, or interest on, any Note, or for any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of the Issuer in this
Indenture or in any supplemental indenture or in any Note or in any Guarantee, or because of the
creation of any indebtedness represented thereby, shall be had against any incorporator,
shareholder, partner, member, manager, employee, agent, officer, trustee, director or subsidiary,
as such, past, present or future, of the Issuer or any of the Issuer’s Subsidiaries or of any
successor thereto, either directly or through the Issuer or any of the Issuer’s Subsidiaries or any
successor thereto, whether by virtue of any constitution, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise; it being expressly understood that all such
liability is hereby expressly waived and released as a condition of, and as a consideration for,
the execution of this Indenture and the issue of the Notes.

ARTICLE 13

Conversion of Notes

Section 13.01. Right to Convert.

(a) Subject to the restrictions on ownership of Common Shares as set forth in Section 13.14
and upon compliance with the provisions of this Indenture, the holder of any Notes may convert its
Notes, or any portion thereof which is a multiple of $1,000, into cash and, if applicable, Common
Shares by surrender of such Notes so to be converted in whole or in part, together with any
required funds, under the circumstances and in the manner described in this Article 13. Holders
may surrender any Notes for conversion not previously redeemed or repurchased at the applicable
Conversion Rate prior to the close of business on the second Business Day immediately preceding the
Stated Maturity of the Notes at any time on or after April 15, 2026 and also upon the occurrence of
one of the events set forth in clauses (i) through (v) below.

(i) Conversion Upon Satisfaction of Market Price Condition. A holder may surrender any
of its Notes for conversion during any calendar quarter beginning after June 30, 2007 (and
only during such calendar quarter) if, and only if, the Closing Sale Price of the Common
Shares for at least twenty (20) Trading Days (whether or not consecutive) in the period of
thirty (30) consecutive Trading Days ending on the last Trading Day of the preceding
calendar quarter is more than 120% of the Conversion Price per Common Share in effect on the
applicable Trading Day. The Board of Trustees will make appropriate adjustments, in its
good faith determination, to account for any adjustment to the Conversion Rate that becomes
effective, or any event requiring an adjustment to the Conversion Rate where the ex-dividend
date of the event occurs, during that thirty (30) consecutive Trading Day period.

(ii) Conversion Upon Satisfaction of Trading Price Condition. A holder may surrender
any of its Notes for conversion during the five (5) consecutive Trading Day period following
any five (5) consecutive Trading Day period in which the Trading Price per $1,000 principal
amount of Notes (as determined following a reasonable request by a holder of the Notes) was
less than 98% of the product of the Closing Sale Price of the Common Shares multiplied by
the Conversion Rate.

“Trading Price” means, with respect to the Notes on any date of determination, the
average of the secondary market bid quotations per $1,000 principal amount of Notes obtained
by the Trustee for a $5,000,000 principal amount of Notes at approximately 3:30 p.m., New
York City time, on such determination date from two independent nationally recognized
securities dealers selected by the Issuer, which may include the Initial Purchaser or any
successor to the Initial Purchaser. If at least two such bids cannot reasonably be obtained
by the Trustee, but one such bid can reasonably be obtained by the Trustee, then one bid
shall be used. If the Trustee cannot reasonably obtain at least one bid for a $5,000,000
principal amount of Notes from a nationally recognized securities dealer or, in the
reasonable judgment of the Issuer, the bid quotations are not indicative of the secondary
market value of the Notes, then the Trading Price per $1,000 principal amount of Notes shall
be deemed to be less than 98% of the product of the Closing Sale Price of the Common Shares
and the Conversion Rate on such determination date.

The Trustee shall have no obligation to determine the Trading Price of the Notes unless
the Issuer shall have requested such determination, and the Issuer shall have no obligation
to make such request unless a holder provides the Issuer with written reasonable evidence
that the Trading Price per $1,000 principal amount of the Notes would be less than 98% of
the product of the Closing Sale Price of the Common Shares and the Conversion Rate,
whereupon the Issuer shall instruct the Trustee to determine the Trading Price of the Notes
beginning on the next Trading Day and on each successive Trading Day until the Trading Price
is greater than or equal to 98% of the product of the Closing Sale Price of the Common
Shares and the applicable Conversion Rate.

(iii) Conversion Upon Notice of Redemption. A holder may surrender for conversion any
of the Notes called for redemption at any time prior to the close of business on the second
Business Day prior to the Redemption Date, even if the Notes are not otherwise convertible
at such time. The right to convert Notes pursuant to this Section 13.01(a)(iii) will expire
after the close of business on the second Business Day prior to the Redemption Date unless
the Issuer defaults in making the payment due upon redemption. A holder may convert fewer
than all of its Notes so long as the Notes converted are an integral multiple of $1,000
principal amount and the remaining principal amount of Notes is in an authorized
denomination. However, if a holder has already delivered a Change in Control Purchase Notice
pursuant to Section 3.05 hereof or an Optional Repurchase Notice pursuant to Section 3.06
hereof with respect to a Note, such holder may not surrender such Note for conversion until
it has withdrawn such notice in accordance with the applicable provisions of Section 3.05 or
Section 3.06 hereof, as the case may be.

(iv) Conversion Upon Specified Transactions. If the Issuer elects to: (1) distribute
to all holders of Common Shares rights entitling them to purchase, for a period expiring
within forty five (45) days after the date fixed for determination of shareholders entitled
to receive such rights, Common Shares at less than the Closing Sale Price of the Common
Shares on the Trading Day immediately preceding the declaration date of such distribution;
or (ii) distribute to all holders of Common Shares assets, debt securities or certain rights
to purchase securities of the Issuer, which distribution has a per share value (as
determined in good faith by the Board of Trustees of the Issuer) exceeding 15% of the
Closing Sale Price of Common Shares on the Trading Day immediately preceding the declaration
date of such distribution, the Issuer shall notify holders of the Notes at least forty-five
(45) calendar days prior to the ex-dividend date for such distribution. Following the
issuance of such notice, holders may surrender their Notes for conversion at any time until
the earlier of the close of business on the Business Day prior to the ex-dividend date or an
announcement by the Issuer that such distribution will not take place; provided, however,
that a holder may not convert its Notes pursuant to this Section 13.01(a)(iv) if such holder
may participate, on an as-converted basis (assuming for this purpose that the Notes were
convertible solely into Common Shares at the then applicable Conversion Rate), in the
distribution without any conversion of Notes. The “ex-dividend date” means, with respect to
any distribution on Common Shares, the first date upon which a sale of Common Shares does
not automatically transfer the right to receive the relevant distribution from the seller of
Common Shares to the buyer.

In addition, if the Issuer is party to a consolidation, merger or binding share
exchange pursuant to which all of the Common Shares would be exchanged for cash, securities
or other property that is not otherwise a Change in Control, a holder may surrender Notes
for conversion at any time from and including the date that is fifteen (15) Business Days
prior to the anticipated Effective Date of the transaction up to and including five (5)
Business Days after the Effective Date of such transaction. The Issuer shall notify holders
of Notes as promptly as practicable following the date it publicly announces such
transaction (but in no event less than fifteen (15) Business Days prior to the anticipated
effective time of such transaction).

If a Change in Control occurs as a result of a transaction described in clauses (1) or
(2) of the definition of “Change in Control,” a holder will have the right to convert its
Notes at any time from and including the Effective Date of such transaction up to and
including the 30th Business Day following the Effective Date of the transaction. The Issuer
will notify holders as promptly as practicable following the date that it publicly announces
such Change in Control (but in no event later than fifteen (15) Business Days prior to the
Effective Date of such Change in Control).

(v) Conversion Upon Delisting of the Common Shares. A holder of Notes may surrender any
of its Notes for conversion at any time beginning on the first Business Day after the Common
Shares have ceased to be listed on a U.S. national or regional securities exchange for a 30
consecutive Trading Day period.

(b) Whenever the Notes shall become convertible pursuant to this Section 13.01, the Issuer or,
at the Issuer’s request, the Trustee in the name and at the expense of the Issuer, shall notify the
holders of the event triggering such convertibility in the manner provided in Section 15.03, and
the Issuer shall also publicly announce such information and publish it on its web site. Any
notice so given shall be conclusively presumed to have been duly given, whether or not the holder
receives such notice.

(c) A Note in respect of which a holder has delivered a Change in Control Purchase Notice
pursuant to Section 3.05 or an Optional Purchase Notice pursuant to Section 3.06 exercising such
holder’s right to require the Issuer to repurchase such Note pursuant to Section 3.05 or Section
3.06, as the case may be, may be converted only if such Change in Control Purchase Notice or
Optional Repurchase Notice is withdrawn in accordance with Section 3.05 or Section 3.06, as the
case may be, prior to the close of business on the third Business Day prior to the Change in
Control Repurchase Date or the Optional Repurchase Date, as the case may be.

(d) A holder of Notes is not entitled to any rights of a holder of Common Shares until such
holder has converted its Notes and received upon conversion thereof Common Shares. The person in
whose name any certificate or certificates for Common Shares shall be issuable upon such
conversion, if any, shall become on the date any such certificate or certificates are delivered to
such holder in accordance with the provisions of this Article 13, the holder of record of the
shares represented thereby.

Section 13.02. Exercise of Conversion Right; No Adjustment for Interest or Dividends. In order to
exercise the conversion right with respect to any Note in certificated form, the Issuer must
receive at the office or agency of the Issuer maintained for that purpose in The City of New York
or, at the option of such holder, the Corporate Trust Office, such Note with the original or
facsimile of the form entitled “Conversion Notice” on the reverse thereof, duly completed and
manually signed, together with such Notes duly endorsed for transfer, accompanied by the funds, if
any, required by this Section 13.02. Such notice shall also state the name or names (with address
or addresses) in which the certificate or certificates for Common Shares, if any, which shall be
issuable on such conversion shall be issued (if other than in the name of the holder tendering such
Note for conversion), and shall be accompanied by transfer or similar taxes, if required pursuant
to Section 13.07.

In order to exercise the conversion right with respect to any interest in a Global Note, the
beneficial holder must complete, or cause to be completed, the appropriate instruction form for
conversion pursuant to the Depositary’s book-entry conversion program; deliver, or cause to be
delivered, by book-entry delivery such interest in such Global Note; furnish appropriate
endorsements and transfer documents if required by the Issuer or the Trustee or the Conversion
Agent; and pay the funds, if any, required by this Section 13.02 and any transfer taxes if required
pursuant to Section 13.07.

Each conversion shall be deemed to have been effected as to any such Note (or portion thereof)
on the date on which the requirements set forth above in this Section 13.02 have been satisfied as
to such Note (or portion thereof) (the “Conversion Date”).

Except as set forth in the next succeeding paragraph, upon conversion of a Note, a holder
shall not be entitled to receive any cash payment in respect of interest, and the Issuer shall not
be required to adjust the Conversion Rate to account for any accrued and unpaid interest (including
Additional Interest, if any). The delivery by the Issuer to the holder of cash and Common Shares,
if any, upon conversion shall be deemed to satisfy the Issuer’s obligation with respect to Notes
tendered for conversion. Accordingly, upon conversion of Notes, any accrued but unpaid interest
shall be deemed to be paid in full, rather than cancelled, extinguished or forfeited.

Holders of Notes at the close of business on a Record Date for an interest payment shall
receive payment of the interest payable on the corresponding Interest Payment Date notwithstanding
the conversion of such Notes at any time after the close of business on the applicable Record Date
and on or prior to the corresponding Interest Payment Date. Accordingly, any Note or portion
thereof surrendered for conversion after the close of business on the Record Date for any Interest
Payment Date and on or prior to the corresponding Interest Payment Date shall be accompanied by
payment, in immediately available funds or other funds acceptable to the Issuer, of an amount equal
to the interest otherwise payable on such Interest Payment Date on the principal amount being
converted; provided that no such payment need be made (1) if the Issuer has specified a Redemption
Date that is after a Record Date and on or prior to the corresponding Interest Payment Date or (2)
to the extent of any overdue interest and Additional Interest and Special Interest, if any overdue
interest and Additional Interest and Special Interest, as applicable, exists at the time of
conversion with respect to such Notes. Except as otherwise provided above in this Article 13, no
payment or other adjustment shall be made for interest accrued on any Note converted or for
dividends on any shares issued upon the conversion of such Note as provided in this Article 13.

In case any Note of a denomination greater than $1,000 shall be surrendered for partial
conversion, and subject to Section 2.04, the Issuer shall execute and the Trustee shall
authenticate and deliver to the holder of the Note so surrendered, without charge to the holder, a
new Note or Notes in authorized denominations in an aggregate principal amount equal to the
unconverted portion of the surrendered Note.

Upon surrender of a Note for conversion, the holder shall deliver to the Issuer an amount in
cash equal to the amount that the Issuer is required to deduct and withhold under applicable law in
connection with such conversion; provided, however, that if the holder does not deliver such cash,
the Issuer may deduct and withhold from the consideration otherwise deliverable to such holder the
amount required to be deducted and withheld under applicable law.

Upon the conversion of an interest in a Global Note, the Trustee (or other Conversion Agent
appointed by the Issuer), or the Custodian at the direction of the Trustee (or other Conversion
Agent appointed by the Issuer), shall make a notation on such Global Note as to the reduction in
the principal amount represented thereby. The Issuer shall notify the Trustee in writing of any
conversion of Notes effected through any Conversion Agent other than the Trustee.

Section 13.03. Cash Payments in Lieu of Fractional Shares. No fractional shares of Common Shares
or scrip certificates representing fractional shares shall be issued upon conversion of Notes. If
more than one Note shall be surrendered for conversion at one time by the same holder, the number
of full shares that shall be issuable upon conversion shall be computed on the basis of the
aggregate principal amount of the Notes (or specified portions thereof to the extent permitted
hereby) so surrendered. The Issuer shall deliver cash in lieu of any fractional shares of Common
Shares issuable in connection with payment of the settlement amount determined in accordance with
the provisions of Section 13.12 based upon the Average Price.

Section 13.04. Conversion Rate. The Conversion Rate for the Notes is 28.6874 Common Shares per
each $1,000 principal amount of the Notes (herein called the “Conversion Rate”), subject to
adjustment as provided in Sections 13.05 and 13.13.

Section 13.05. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted by the Issuer
from time to time as follows:

(a) If the Issuer issues Common Shares as a dividend or distribution on Common Shares to all
holders of Common Shares, or if the Issuer effects a share split or share combination, the
Conversion Rate will be adjusted based on the following formula:

	 	 	 	CR1 = CR0 x OS1/OS0

	 	 	 	where

	 	 	 	CR0 = the Conversion Rate in effect immediately prior to the
adjustment relating to such event

	 	 	 	CR1 = the new Conversion Rate in effect taking such event into
account

	 	 	 	OS0 = the number of Common Shares outstanding immediately prior to
such event

	 	 	 	OS1 = the number of Common Shares outstanding immediately after
such event.

Any adjustment made pursuant to this clause (a) shall become effective on the date that is
immediately after (x) the date fixed for the determination of shareholders entitled to receive such
dividend or other distribution or (y) the date on which such split or combination becomes
effective, as applicable. If any dividend or distribution described in this clause (a) is declared
but not so paid or made, the new Conversion Rate shall be readjusted to the Conversion Rate that
would then be in effect if such dividend or distribution had not been declared.

(b) If the Issuer issues to all holders of Common Shares any rights, warrants, options or
other securities entitling them for a period of not more than 45 days after the date of issuance
thereof to subscribe for or purchase Common Shares, or if the Issuer issues to all holders of
Common Share securities convertible into Common Shares for a period of not more than 45 days after
the date of issuance thereof, in either case at an exercise price per Common Share or a conversion
price per Common Share less than the Closing Sale Price of the Common Shares on the Business Day
immediately preceding the time of announcement of such issuance, the Conversion Rate will be
adjusted based on the following formula:

	 	 	 	CR1 = CR0 x (OS0+X)/(OS0+Y)

	 	 	 	where

	 	 	 	CR0 = the Conversion Rate in effect immediately prior to the
adjustment relating to such event

	 	 	 	CR1 = the new Conversion Rate taking such event into account

	 	 	 	OS0 = the number of Common Shares outstanding immediately prior to
such event

	 	 	 	X = the total number of Common Shares issuable pursuant to such
rights, warrants, options, other securities or convertible securities

	 	 	 	Y = the number of Common Shares equal to the quotient of (A) the
aggregate price payable to exercise such rights, warrants, options, other
securities or convertible securities and (B) the average of the Closing Sale
Prices of the Common Shares for the 10 consecutive Trading Days prior to the
Business Day immediately preceding the date of announcement for the issuance of
such rights, warrants, options, other securities or convertible securities.

For purposes of this clause (b), in determining whether any rights, warrants, options, other
securities or convertible securities entitle the holders to subscribe for or purchase, or exercise
a conversion right for, Common Shares at less than the applicable Closing Sale Price of the Common
Shares, and in determining the aggregate exercise or conversion price payable for such Common
Shares, there shall be taken into account any consideration received by the Issuer for such rights,
warrants, options, other securities or convertible securities and any amount payable on exercise or
conversion thereof, with the value of such consideration, if other than cash, to be determined by
the Board of Trustees of the Issuer. If any right, warrant, option, other security or convertible
security described in this clause (b) is not exercised or converted prior to the expiration of the
exercisability or convertibility thereof, the new Conversion Rate shall be readjusted to the
Conversion Rate that would then be in effect if such right, warrant, option, other security or
convertible security had not been so issued.

(c) If the Issuer distributes capital shares, evidences of indebtedness or other assets or
property of the Issuer to all holders of Common Shares, excluding:

(i) dividends, distributions, rights, warrants, options, other securities or
convertible securities referred to in clause (a) or (b) above,

(ii) dividends or distributions paid exclusively in cash as described in paragraph (d)
below, and

	 	 	 
	(iii)

	 	Spin-Offs described below in this clause (c),
	 
	 	 
	then the Conversion Rate will be adjusted based on the following formula:

	 
	 	 
	CR1 =

	 	CR0 x SP0/(SP0-FMV)

	 	 	 	where

	 	 	 	CR0 = the Conversion Rate in effect immediately prior to the
adjustment relating to such event

	 	 	 	CR1 = the new Conversion Rate taking such event into account

	 	 	 	SP0 = the average of the Closing Sale Prices of the Common Shares
on the 10 consecutive Trading Days prior to the Business Day immediately
preceding the earlier of the record date or the ex-dividend date for such
distribution

	 	 	 	FMV= the fair market value (as determined in good faith by the Board
of Trustees of the Issuer) of the capital shares, evidences of indebtedness,
assets or property distributed with respect to each outstanding Common Share on
the earlier of the record date or the ex-dividend date for such distribution.

An adjustment to the Conversion Rate made pursuant to the immediately preceding clause shall be
made successively whenever any such distribution is made and shall become effective on the
ex-dividend date for such distribution.

If the Issuer distributes to all holders of Common Shares capital shares of any class or
series, or similar equity interest, of or relating to a subsidiary or other business unit of the
Issuer (a “Spin-Off”), the Conversion Rate in effect immediately before the close of business on
the date fixed for determination of holders of Common Shares entitled to receive such distribution
will be adjusted based on the following formula:

	 	 	 	CR1 = CR0 x (FMV0+MP0)/MP0

	 	 	 	where

	 	 	 	CR0 = the Conversion Rate in effect immediately prior to the
adjustment relating to such event

	 	 	 	CR1 = the new Conversion Rate taking such event into account

	 	 	 	FMV0 =the average of the Closing Sale Prices of the capital shares
or similar equity interest distributed to holders of Common Shares applicable
to one Common Share over the first 10 consecutive Trading Days after the
effective date of the Spin-Off

	 	 	 	MP0 = the average of the Closing Sale Prices of the Common Shares
over the first 10 consecutive Trading Days after the effective date of the
Spin-Off.

An adjustment to the Conversion Rate made pursuant to the immediately preceding clause will occur
on the 10th Trading Day from and including the effective date of the Spin-Off.

If any such dividend or distribution described in this clause (c) is declared but not paid or
made, the new Conversion Rate shall be readjusted to be the Conversion Rate that would then be in
effect if such dividend or distribution had not been declared.

(d) If the Issuer pays or makes any cash dividend or distribution in respect of any of its
quarterly fiscal periods (without regard to when paid) to all holders of Common Shares in an
aggregate amount that, together with other cash dividends or distributions paid or made in respect
of such quarterly fiscal period, exceeds the product of $0.80 (the “Reference Dividend”) multiplied
by the number of Common Shares outstanding on the record date for such distribution, the Conversion
Rate will be adjusted based on the following formula:

	 	 	 	CR1 = CR0 x SP0/(SP0-C)

	 	 	 	where

	 	 	 	CR0 = the Conversion Rate in effect immediately prior to the
adjustment relating to such event

	 	 	 	CR1 = the new Conversion Rate taking such event into account

	 	 	 	SP0 = the average of the Closing Sale Prices of Common Shares on
the 10 consecutive Trading Days immediately prior to the Business Day
immediately preceding the earlier of the record date or the ex-dividend date
for such distribution

	 	 	 	C = the amount in cash per Common Share that the Issuer
distributes to holders of Common Shares in respect of such quarterly fiscal
period that exceeds the Reference Dividend.

An adjustment to the Conversion Rate made pursuant to this clause (d) shall become effective
on the ex-dividend date for such dividend or distribution. If any dividend or distribution
described in this clause (d) is declared but not so paid or made, the new Conversion Rate shall be
readjusted to the Conversion Rate that would then be in effect if such dividend or distribution had
not been declared.

Notwithstanding anything to the contrary in this clause (d), if an adjustment to the
Conversion Rate is required to be made as a result of a distribution that is not a quarterly
dividend either in whole or in part, the Reference Dividend shall be deemed to be zero for purposes
of determining the adjustment to the Conversion Rate as a result of such distribution.

The Reference Dividend shall be subject to adjustment in a manner that is inversely
proportional to adjustments to the Conversion Rate; provided, however, that no adjustments shall be
made to the Reference Dividend for any adjustment made to the Conversion Rate pursuant to this
clause (d).

(e) If the Issuer or any of its subsidiaries makes a payment in respect of a tender offer or
exchange offer for Common Shares to the extent that the cash and value of any other consideration
included in the payment per Common Share exceeds the Closing Sale Price of the Common Shares on the
Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to
such tender or exchange offer (the “Expiration Time”), the Conversion Rate will be adjusted based
on the following formula:

	 	 	 	CR1 = CR0 x (AC + (SP1 x OS1))/(SP1 x OS0)

	 	 	 	where

	 	 	 	CR0 = the Conversion Rate in effect immediately prior to the
adjustment relating to such event

	 	 	 	CR1 = the new Conversion Rate taking such event into account

	 	 	 	AC = the aggregate value of all cash and any other consideration
(as determined by the Board of Trustees of the Issuer) paid or payable for
Common Shares purchased in such tender or exchange offer

	 	 	 	OS0 = the number of Common Shares outstanding immediately prior to
the date such tender or exchange offer expires

	 	 	 	OS1 = the number of Common Shares outstanding immediately after
such tender or exchange offer expires (after giving effect to the purchase or
exchange of shares pursuant to such tender or exchange offer)

	 	 	 	SP1 = the average of the Closing Sale Prices of Common Shares for
the 10 consecutive Trading Days commencing on the Trading Day next succeeding
the date such tender or exchange offer expires.

If the application of the foregoing formula would result in a decrease in the Conversion Rate,
no adjustment to the Conversion Rate will be made.

Any adjustment to the Conversion Rate made pursuant to this clause (e) shall become effective
on the date immediately following the determination of the average of the Closing Sale Prices of
Common Shares for purposes of SP1 above. If the Issuer or one of its subsidiaries is obligated to
purchase Common Shares pursuant to any such tender or exchange offer but is permanently prevented
by applicable law from effecting any such purchase or all such purchases are rescinded, the new
Conversion Rate shall be readjusted to be the Conversion Rate that would be in effect if such
tender or exchange offer had not been made.

(f) Notwithstanding the foregoing, in no event shall the Conversion Rate exceed 36.5764 shares
per $1,000 principal amount of Notes, subject to adjustment pursuant to Section 13.05 (a)-(e)
above.

(g) In addition to the adjustments pursuant to clauses (a) through (e) above, the Issuer may
increase the Conversion Rate in order to avoid or diminish any income tax to holders of Common
Shares resulting from any dividend or distribution of capital shares (or rights to acquire Common
Shares) or from any event treated as such for income tax purposes. The Issuer may also, from time
to time, to the extent permitted by applicable law, increase the Conversion Rate by any amount for
any period if the Issuer has determined that such increase would be in the best interests of the
Issuer. If the Issuer makes such determination, it will be conclusive and the Issuer will mail to
holders of the Notes a notice of the increased Conversion Rate and the period during which it will
be in effect at least fifteen (15) days prior to the date the increased Conversion Rate takes
effect in accordance with applicable law.

(h) If, in connection with any adjustment to the Conversion Rate as set forth in this Section
13.05 a holder shall be deemed for U.S. federal tax purposes to have received a distribution, the
Issuer may set off any withholding tax it reasonably believes it is required to collect with
respect to any such deemed distribution against cash payments of interest in accordance with the
provisions of Section 4.01 hereof or from cash and Common Shares, if any, otherwise deliverable to
a holder upon a conversion of Notes in accordance with the provisions of Section 13.12 hereof or a
redemption or repurchase of a Note in accordance with the provisions of Article 3 hereof.

(i) The Issuer will not make any adjustment to the Conversion Rate if holders of the Notes are
permitted to participate, on an as-converted basis, in the transactions described above (assuming
for this purpose that the Notes were convertible solely into Common Shares at the then applicable
Conversion Rate).

(j) Notwithstanding anything to the contrary contained herein, in addition to the other events
set forth herein on account of which no adjustment to the Conversion Rate shall be made, the
applicable Conversion Rate shall not be adjusted for: (i) the issuance of any Common Shares
pursuant to any present or future plan providing for the reinvestment of dividends or interest
payable on securities of the Issuer and the investment of additional optional amounts in Common
Shares under any plan; (ii) the issuance of any Common Shares or options or rights to purchase
those shares pursuant to any present or future employee, trustee, director or consultant benefit
plan, employee agreement or arrangement or program of the Issuer; (iii) the issuance of any Common
Shares pursuant to any option, warrant, right, or exercisable, exchangeable or convertible security
outstanding as of the date the Notes were first issued; (iv) a change in the par value of the
Common Shares; (v) accumulated and unpaid dividends or distributions; and (vi) as a result of a
tender offer solely to holders of fewer than 100 Common Shares.

(k) No adjustment in the Conversion Rate will be required unless the adjustment would require
an increase or decrease of at least 1% of the Conversion Rate. If the adjustment is not made
because the adjustment does not change the Conversion Rate by at least 1%, then the adjustment that
is not made will be carried forward and taken into account in any future adjustment. All required
calculations will be made to the nearest cent or 1/1000th of a share, as the case may be.
Notwithstanding the foregoing, all adjustments not previously made will have effect with respect to
any conversion of the Notes.

(l) Whenever the Conversion Rate is adjusted as herein provided, the Issuer shall promptly
file with the Trustee and any Conversion Agent other than the Trustee, an Officers’ Certificate
setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the
facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have
received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any
adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has
knowledge is still in effect. Promptly after delivery of such certificate, the Issuer shall
prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion
Rate and the date on which each adjustment becomes effective and shall mail such notice of such
adjustment of the Conversion Rate to the holders of the Notes within 20 Business Days of the
effective date of such adjustment. Failure to deliver such notice shall not affect the legality or
validity of any such adjustment.

(m) For purposes of this Section 13.05, the number of Common Shares at any time outstanding
shall not include shares held in the treasury of the Issuer but shall include shares issuable in
respect of scrip certificates issued in lieu of fractions of Common Shares.

(n) Notwithstanding anything in this Section 13.05 to the contrary, in no event shall the
Conversion Rate be adjusted so that the Conversion Price would be less than $0.01.

Section 13.06. Change in Conversion Right Upon Certain Reclassifications, Business
Combinations and Asset Sales.

(a) If the Issuer is a party to a consolidation, merger or binding share exchange (including,
without limitation, by way of a recapitalization, reclassification or change of Common Shares
(other than changes resulting from a subdivision or combination) or a sale, lease or transfer to a
third party of the Issuer’s and the Issuer’s subsidiaries’ consolidated assets substantially as an
entirety) pursuant to which all of the Common Shares are exchanged for cash, securities or other
property, then the Issuer, or such successor or purchasing corporation, as the case may be, shall,
as a condition precedent to such consolidation, merger or binding share exchange or sale, lease or
transfer, execute and deliver to the Trustee a supplemental indenture providing that from and after
the Effective Date of the transaction any conversion of Notes and the Conversion Value will be
based on, and determined by reference to, the kind and amount of cash, securities or other property
that the holder would have received if such holder had converted its Notes into Common Shares
immediately prior to the Effective Date of the transaction.

(b) In the event the Issuer shall execute a supplemental indenture pursuant to this Section
13.06, the Issuer shall promptly file with the Trustee an Opinion of Counsel stating that such
supplemental indenture is authorized or permitted by this Indenture and an Officers’ Certificate
briefly stating the reasons therefor, the kind or amount of cash, securities or other property
receivable by holders of the Notes upon the conversion of their Notes after any such
reclassification, change, consolidation, merger, binding share exchange, sale, transfer, lease or
conveyance, any adjustment to be made with respect thereto and that all conditions precedent have
been complied with.

(c) For purposes of this Section 13.06, where a consolidation, merger or binding share
exchange involves a transaction that causes Common Shares to be exchanged for the right to receive
more than a single type of consideration based upon any form of shareholder election, such
consideration will be deemed to be the weighted average of the types and amounts of consideration
received by the holders of Common Shares that affirmatively make such an election.

(d) If this Section 13.06 applies to any event or occurrence, Section 13.05 shall not apply.
The provisions of this Section 13.06 shall similarly apply to successive reclassifications,
changes, consolidations, mergers, sales, transfers, leases, conveyances or other dispositions.

Section 13.07. Taxes on Shares Issued. The issue of share certificates, if any, on conversion of
Notes shall be made without charge to the converting Noteholder for any documentary, stamp or
similar issue or transfer tax in respect of the issue thereof. The Issuer shall not, however, be
required to pay any such tax which may be payable in respect of any transfer involved in the issue
and delivery of shares in any name other than that of the holder of any Note converted, and the
Issuer shall not be required to issue or deliver any such share certificate unless and until the
Person or Persons requesting the issue thereof shall have paid to the Issuer the amount of such tax
or shall have established to the satisfaction of the Issuer that such tax has been paid.

Section 13.08. Reservation of Shares, Shares to be Fully Paid; Compliance with Governmental
Requirements. The Issuer shall provide, free from preemptive rights, out of its authorized but
unissued shares or shares held in treasury, sufficient Common Shares to provide for the conversion
of the Notes as required by this Indenture from time to time as such Notes are presented for
conversion.

Before taking any action which would cause an adjustment increasing the Conversion Rate to an
amount that would cause the Conversion Price to be reduced below the then par value, if any, of the
Common Shares issuable, if any, upon conversion of the Notes, the Issuer will take all corporate
action which may, in the opinion of its counsel, be necessary in order that the Issuer may validly
and legally issue such Common Shares at such adjusted Conversion Rate.

The Issuer covenants that all Common Shares, if any, which may be issued upon conversion of
Notes will upon issue be fully paid and non-assessable and free from all taxes, liens and charges
with respect to the issue thereof.

Section 13.09. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at
any time be under any duty or responsibility to any holder of Notes to determine the Conversion
Rate or whether any facts exist which may require any adjustment of the Conversion Rate, or with
respect to the nature or extent or calculation of any such adjustment when made, or with respect to
the method employed, or herein or in any supplemental indenture provided to be employed, in making
the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the
validity or value (or the kind or amount) of any Common Shares, or of any capital shares, other
securities or other assets or property, which may at any time be issued or delivered upon the
conversion of any Note; and the Trustee and any other Conversion Agent make no representations with
respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure
of the Issuer to issue, transfer or deliver any Common Shares or share certificates or other
securities or property or cash upon the surrender of any Note for the purpose of conversion or to
comply with any of the duties, responsibilities or covenants of the Issuer contained in this
Article 13. Without limiting the generality of the foregoing, neither the Trustee nor any
Conversion Agent shall be under any responsibility to determine the correctness of any provisions
contained in any supplemental indenture entered into pursuant to Section 13.06 relating either to
the kind or amount of capital shares or other securities or other assets or property (including
cash) receivable by Noteholders upon the conversion of their Notes after any event referred to in
such Section 13.06 or to any adjustment to be made with respect thereto, but, subject to the
provisions of Section 7.01, may accept as conclusive evidence of the correctness of any such
provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Issuer
shall be obligated to file with the Trustee prior to the execution of any such supplemental
indenture) with respect thereto. The Trustee shall not at any time be under any duty or
responsibility to any holder of Notes to determine the accuracy of the method employed in
calculating the Trading Price or whether any facts exist which may require any adjustment of the
Trading Price.

Section 13.10. Notice to Holders Prior to Certain Actions. In case:

(a) the Issuer shall declare a dividend (or any other distribution) on its Common Shares that
would require an adjustment in the Conversion Rate pursuant to Section 13.05; or

(b) the Issuer shall authorize the granting to the holders of all or substantially all of its
Common Shares of rights or warrants to subscribe for or purchase any share of any class or any
other rights or warrants; or

(c) of any reclassification or reorganization of the Common Shares (other than a subdivision
or combination of its outstanding Common Shares, or a change in par value, or from par value to no
par value, or from no par value to par value), or of any consolidation, combination, merger or
share exchange to which the Issuer is a party and for which approval of any shareholders of the
Issuer is required, or of the sale or transfer of all or substantially all of the assets of the
Issuer; or

(d) of the voluntary or involuntary dissolution, liquidation or winding up of the Issuer;

the Issuer shall cause to be filed with the Trustee and to be mailed to each holder of Notes at its
address appearing on the Note Register provided for in Section 2.05 of this Indenture, as promptly
as possible but in any event at least ten (10) calendar days prior to the applicable date
hereinafter specified, a notice stating (x) the date on which a record is to be taken for the
purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken,
the date as of which the holders of Common Share of record to be entitled to such dividend,
distribution or rights are to be determined, or (y) the date on which such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become
effective or occur, and the date as of which it is expected that holders of Common Share of record
shall be entitled to exchange their Common Shares for securities or other property deliverable upon
such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding
up. Failure to give such notice, or any defect therein, shall not affect the legality or validity
of such dividend, distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up.

Section 13.11. Shareholder Rights Plans. If the Issuer has in effect a rights plan while any Notes
remain outstanding, holders of Notes will receive, upon a conversion of Notes in respect of which
the Issuer shall deliver Common Shares, in addition to such Common Shares, rights under the
Issuer’s shareholder rights agreement unless, prior to conversion, the rights have expired,
terminated or been redeemed or unless the rights have separated from the Common Shares. If the
rights provided for in the rights plan adopted by the Issuer have separated from the Common Shares
in accordance with the provisions of the applicable shareholder rights agreement so that holders of
Notes would not be entitled to receive any rights in respect of Common Shares, if any, that the
Issuer delivers upon conversion of Notes, the Conversion Rate will be adjusted at the time of
separation as if the Issuer had distributed to all holders of Common Share capital shares,
evidences of indebtedness or other assets or property pursuant to Section 13.05(c) above, subject
to readjustment upon the subsequent expiration, termination or redemption of the rights.

Section 13.12. Settlement Upon Conversion. Upon a conversion of Notes, the Issuer shall deliver,
in respect of each $1,000 principal amount of Notes surrendered for conversion in accordance with
their terms:

(a) cash in an amount (the “Principal Return”) equal to the lesser of (1) the principal amount
of the Notes surrendered for conversion and (2) the Conversion Value, and

(b) if the Conversion Value is greater than the Principal Return, an amount (the “Net Amount”)
in cash or Common Shares, at the Issuer’s option, with an aggregate value equal to the difference
between the Conversion Value and the Principal Return.

The Issuer may elect to deliver any portion of the Net Amount in cash (the “Net Cash Amount”)
or Common Shares, and any portion of the Net Amount the Issuer elects to deliver in Common Shares
(the “Net Shares”) will be the sum of the Daily Share Amounts for each Trading Day during the
Applicable Conversion Period. Prior to the close of business on the second Trading Day following
the date on which Notes are surrendered for conversion, the Issuer shall inform Holders of such
Notes of its election to pay cash for all or a portion of the Net Amount and, if applicable, the
portion of the Net Amount that will be paid in cash and the portion that will be delivered in the
form of Net Shares.

The Issuer shall deliver cash in lieu of any fractional Common Shares issuable in connection
with payment of the Net Shares based upon the Average Price.

The “Daily Share Amount” for each $1,000 principal amount of Notes and each Trading Day in the
Applicable Conversion Period is equal to the greater of:

(c) zero; and

(d) a number of Common Shares determined by the following formula:

where

CSP means the Closing Sale Price of the Common Shares on such Trading Day, and

CR means the applicable Conversion Rate.

The Issuer will determine the Conversion Value, Principal Return, Net Amount, Net Cash Amount
and the number of Net Shares, as applicable, promptly after the end of the Applicable Conversion
Period. The Issuer shall pay the Principal Return and cash in lieu of fractional shares, and
deliver Net Shares or pay the Net Cash Amount, as applicable, no later than the third Business Day
following the last Trading Day of the Applicable Conversion Period.

Section 13.13. Conversion Rate Adjustment After Certain Change in Control Transactions.

(a) If the Effective Date of a Change in Control occurs prior to April 20, 2012 as a result of
a transaction or event described in clauses (1) or (2) of the definition of Change in Control and a
holder elects to convert its Notes in connection with such Change in Control pursuant to Section
13.01(a)(iv) hereof, the Issuer shall increase the applicable Conversion Rate for such Notes
surrendered for conversion by a number of additional Common Shares (the “Additional Shares”) as
specified below. A conversion of Notes will be deemed for these purposes to be “in connection
with” such a Change in Control if the Conversion Notice is received by the Conversion Agent on any
date from and including the date that is the Effective Date of such Change in Control up to and
including the 30th Business Day following the Effective Date of such Change in Control.

(b) The number of Additional Shares will be determined by reference to the table in Section
13.13(e) and is based on the date on which the Change in Control becomes effective (the “Effective
Date”) and the price paid per Common Share in the Change in Control transaction (the “Share
Price”). If holders of Common Shares receive only cash in the Change in Control transaction, the
Share Price shall equal the cash amount paid per Common Share in such transaction. In all other
cases, the Share Price shall equal the average of the Closing Sale Prices of the Common Shares on
the ten (10) consecutive Trading Days up to but excluding the Effective Date.

(c) The Share Prices set forth in the first row of the table set forth in Section 13.13(e)
(i.e., the column headers) shall be adjusted as of any date on which the Conversion Rate of the
Notes is adjusted pursuant to Section 13.05. The adjusted Share Prices shall equal the Share
Prices applicable immediately prior to such adjustment multiplied by a fraction, (i) the numerator
of which shall be the Conversion Rate immediately prior to the adjustment giving rise to the Share
Price adjustment and (ii) the denominator of which shall be the Conversion Rate as so adjusted.

(d) The number of Additional Shares shall be adjusted in the same manner and for the same
events as the Conversion Rate is adjusted pursuant to Section 13.05.

365-day year;

(ii) If the Share Price is equal to or in excess of $80.00 per Common Share (subject to

conversion of Notes; and

(iii) If the Share Price is less than $27.34 per Common Share (subject to adjustment as

amount of Notes, subject to adjustment in the same manner as the Conversion Rate as set forth in
Section 13.05.

Section 13.14. Ownership Limit; Withholding Tax.

(a) Notwithstanding any other provision of the Notes, no holder of Notes shall be entitled to
receive Common Shares upon a conversion of Notes to the extent that receipt of such shares would
cause such holder (together with such holder’s Affiliates) to exceed the ownership limit contained
in the Charter of the Issuer.

(b) At the Stated Maturity or upon earlier redemption or repurchase of the Notes or otherwise,
and as otherwise required by law, the Issuer may deduct and withhold from the amount of
consideration otherwise deliverable to the holder the amount required to be deducted and withheld
under applicable law.

Section 13.15. Calculation In Respect of Notes. Except as otherwise specifically stated herein or
in the Notes, all calculations to be made in respect of the Notes shall be the obligation of the
Issuer. All calculations made by the Issuer or its agent as contemplated pursuant to the terms
hereof and of the Notes shall be made in good faith and be final and binding on the Notes and the
holders of the Notes absent manifest error. The Issuer shall provide a schedule of calculations to
the Trustee, and the Trustee shall be entitled to rely upon the accuracy of the calculations by the
Issuer without independent verification. The Trustee shall forward calculations made by the Issuer
to any holder of Notes upon request within twenty (20) Business Days of the effective date of any
adjustment.

ARTICLE 14

Note Guarantees

Section 14.01. Guarantees.

(a) Each Guarantor, hereby jointly and severally, absolutely, unconditionally and irrevocably
guarantees the Notes and obligations of the Issuer hereunder and thereunder, and guarantees to each
holder of a Note authenticated and delivered by the Trustee, and to the Trustee on behalf of such
holder, that (i) the principal of and interest on the Notes will be paid in full when due, whether
at the Stated Maturity of the Notes, a Redemption Date, a Change in Control Repurchase Date or an
Optional Repurchase Date, by acceleration or otherwise (including, without limitation, the amount
that would become due but for the operation of any automatic stay provision of any Bankruptcy Law),
together with interest on the overdue principal, if any, and interest on any overdue interest, to
the extent lawful, and all other obligations of the Issuer to the holders or the Trustee hereunder
or thereunder will be paid in full or performed or observed, all in accordance with the terms
hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or
of any such other obligations, the same will be paid in full when due or performed or observed in
accordance with the terms of the extension or renewal, whether at the Stated Maturity of the Notes,
a Redemption Date, a Change in Control Repurchase Date or an Optional Repurchase Date, by
acceleration or otherwise, subject, however, in the case of clauses (i) and (ii) above, to the
limitations set forth in Section 14.03 hereof.

Each Guarantor hereby agrees that its obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any holder of Notes with
respect to any provisions hereof or thereof, any release of any other Guarantor, the recovery of
any judgment against the Issuer, any action to enforce the same or any other circumstance which
might otherwise constitute a legal or equitable discharge or defense of a Guarantor.

(b) Each Guarantor hereby waives (to the extent permitted by law) the benefits of diligence,
presentment, demand for payment, filing of claims with a court in the event of insolvency or
bankruptcy of the Issuer, any right to require a proceeding first against the Issuer or any other
Person, protest, notice and all demands whatsoever and covenants that the Guarantee of such
Guarantor shall not be discharged as to Notes except by complete performance of the obligations
contained therein, this Indenture and such Guarantee. Each Guarantor acknowledges that the
Guarantee is a guarantee of payment and not of collection. Each of the Guarantors hereby agrees
that, in the event of a default in payment of principal or interest on such Note, whether at the
Stated Maturity of the Notes, a Redemption Date, a Change in Control Repurchase Date or an Optional
Repurchase Date, by acceleration or otherwise, legal proceedings may be instituted by the Trustee
on behalf of, or by, the holder of such Note, subject to the terms and conditions set forth in this
Indenture, directly against each of the Guarantors to enforce such Guarantor’s Guarantee without
first proceeding against the Issuer or any other Guarantor. Each Guarantor agrees that if, after
the occurrence and during the continuance of an Event of Default, the Trustee or any of the holders
are prevented by applicable law from exercising their respective rights to accelerate the maturity
of the Notes, to collect interest on the Notes, or to enforce or exercise any other right or remedy
with respect to the Notes, such Guarantor will pay to the Trustee for the account of the holders,
upon demand therefor, the amount that would otherwise have been due and payable had such rights and
remedies been permitted to be exercised by the Trustee or any of the holders.

(c) If any holder or the Trustee is required by any court or otherwise to return to the Issuer
or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in
relation to either the Issuer or any Guarantor , any amount paid by any of them to the Trustee or
such holder, the Guarantee of each of the Guarantors, to the extent theretofore discharged, shall
be reinstated in full force and effect. Each Guarantor further agrees that, as between each
Guarantor, on the one hand, and the holders and the Trustee, on the other hand, (x) subject to this
Article 14, the maturity of the obligations guaranteed hereby may be accelerated as provided in
Article 6 hereof for the purposes of the Guarantee of such Guarantor, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in
Article 6 hereof, such obligations (whether or not due and payable) shall forthwith become due and
payable by each Guarantor for the purpose of the Guarantee of such Guarantor.

(d) Each Guarantee shall remain in full force and effect and continue to be effective should
any petition be filed by or against the Issuer for liquidation or reorganization, should the Issuer
become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee
be appointed for all or any significant part of the Issuer’s assets, and shall, to the fullest
extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any
time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in
amount, or must otherwise be restored or returned by any obligee on the Notes, whether as a
“voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or
performance had not been made. In the event that any payment, or any part thereof, is rescinded,
reduced, restored or returned, the Securities shall, to the fullest extent permitted by law, be
reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or
returned.

(e) To evidence its Guarantee, each Guarantor hereby agrees that a Notation of Guarantee
substantially in the form attached as Exhibit B hereto will be endorsed by an Officer of such
Guarantor on each Note authenticated and delivered to the Trustee. Each Guarantor hereby agrees
that its Guarantee will remain in full force and effect notwithstanding any failure to endorse on
each Note a Notation of Guarantee. The delivery of any Note by the Trustee, after the
authentication thereof hereunder, will be deemed to constitute due delivery of the Notation of
Guarantee set forth in this Indenture by the Guarantors.

Section 14.02. Severability. In case any provision of any Guarantee shall be invalid, illegal or
unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

Section 14.03. Limitation of Liability. Each Guarantor and by its acceptance hereof each holder
confirms that it is the intention of all such parties that the Guarantee by each such Guarantor
pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of the
Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any
similar federal or state law or the provisions of its local law relating to fraudulent transfer or
conveyance. To effectuate the foregoing intention, the holders and each such Guarantor hereby
irrevocably agree that the obligations of such Guarantor under its Guarantee shall be limited to
the maximum amount that will not, after giving effect to all other contingent and fixed liabilities
of such Guarantor and after giving effect to any collections from or payments made by or on behalf
of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or
pursuant to this Article 14, result in the obligations of such Guarantor under its Guarantee
constituting such fraudulent transfer or conveyance.

Section 14.04. Contribution. In order to provide for just and equitable contribution among the
Guarantors, the Guarantors agree, inter se, that in the event any payment or distribution is made
by any Guarantor under a Guarantee, such Guarantor will be entitled to a contribution from any
other Guarantor in a pro rata amount based on the net assets of each Guarantor determined in
accordance with GAAP.

Section 14.05. Subrogation. Each Guarantor shall be subrogated to all rights of holders against
the Issuer in respect of any amounts paid by any Guarantor pursuant to the provisions of
Section 14.01; provided, however, that if an Event of Default has occurred and is continuing, no
Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such
right of subrogation until all amounts then due and payable by the Issuer under this Indenture or
the Notes shall have been paid in full.

Section 14.06. Reinstatement. Each Guarantor hereby agrees (and each Person who becomes a
Guarantor shall agree) that the Guarantee provided for in Section 14.01 shall continue to be
effective or be reinstated, as the case may be, if at any time, payment, or any part thereof, of
any obligations or interest thereon is rescinded or must otherwise be restored by a Holder to the
Issuer upon the bankruptcy or insolvency of the Issuer or any Guarantor.

Section 14.07. Release of a Guarantor. Notwithstanding the foregoing, each Guarantee by a
Guarantor of the Notes shall provide by its terms that it shall be automatically and
unconditionally released and discharged upon (i) any sale, exchange or transfer, to any Person not
an Affiliate of the Issuer, of all of the Issuer’s capital stock in, or all or substantially all
the assets of, such Guarantor, which transaction is in compliance with the terms of this Indenture
and pursuant to which transaction such Guarantor is released from all guarantees, if any, by it of
other indebtedness of the Issuer or any of its Subsidiaries or (ii) payment in full of all
principal and interest on the Notes.

Section 14.08. Benefits Acknowledged. Each Guarantor acknowledges that it will receive direct and
indirect benefits from the financing arrangements contemplated by this Indenture and that its
respective Guarantee and waiver pursuant to its respective Guarantee is knowingly made in
contemplation of such benefits.

indentures qualified under the Trust Indenture Act; provided that this Section 15.07 shall not
require this Indenture or the Trustee to be qualified under the Trust Indenture Act prior to the

Indenture Act, such required provision shall control.

Section 15.08. No Security Interest Created. Nothing in this Indenture or in the Notes, expressed

authenticating agent, any Note Registrar and their successors hereunder and the holders of Notes
any benefit or any legal or equitable right, remedy or claim under this Indenture.

Section 15.10. Table of Contents, Headings, etc. The table of contents and the titles and headings

hereunder, including under Sections 2.04, 2.05, 2.06, 2.07, 3.03, 3.05 and 3.06, as fully to all
intents and purposes as though the authenticating agent had been expressly authorized by this
Indenture and those Sections to authenticate and deliver Notes. For all purposes of this
Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to
be authentication and delivery of such Notes “by the Trustee” and a certificate of authentication
executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any
requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such
authenticating agent shall at all times be a Person eligible to serve as trustee hereunder pursuant
to Section 7.09.

Any corporation into which any authenticating agent may be merged or exchanged or with which
it may be consolidated, or any corporation resulting from any merger, consolidation or exchange to

trust business of any authenticating agent, shall be the successor of the authenticating agent
hereunder, if such successor corporation is otherwise eligible under this Section 15.11, without
the execution or filing of any paper or any further act on the part of the parties hereto or the
authenticating agent or such successor corporation.

Any authenticating agent may at any time resign by giving written notice of resignation to the
Trustee and to the Issuer. The Trustee may at any time terminate the agency of any authenticating
agent by giving written notice of termination to such authenticating agent and to the Issuer. Upon
receiving such a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible under this Section, the Trustee shall either
promptly appoint a successor authenticating agent or itself assume the duties and obligations of
the former authenticating agent under this Indenture and, upon such appointment of a successor
authenticating agent, if made, shall give written notice of such appointment of a successor
authenticating agent to the Issuer and shall mail notice of such appointment of a successor
authenticating agent to all holders of Notes as the names and addresses of such holders appear on
the Note Register.

The Issuer agrees to pay to the authenticating agent from time to time such reasonable
compensation for its services as shall be agreed upon in writing between the Issuer and the
authenticating agent.

The provisions of Sections 7.02, 7.03, 7.04 and 8.03 and this Section 15.11 shall be
applicable to any authenticating agent.

Section 15.12. Execution in Counterparts. This Indenture may be executed in any number of
counterparts, each of which shall be an original, but such counterparts shall together constitute
but one and the same instrument.

Section 15.13. Severability. In case any provision in this Indenture or in the Notes or Guarantees
shall be invalid, illegal or unenforceable, then (to the extent permitted by law) the validity,
legality and enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

FORM OF REVERSE OF NOTE

RAIT FINANCIAL TRUST

6.875% CONVERTIBLE SENIOR NOTES DUE 2027

This note is one of a duly authorized issue of notes of the Issuer, designated as its “6.875%
Convertible Senior Notes due 2027” (herein called the “Notes”), issued under and pursuant to an
Indenture, dated as of April 18, 2007 (herein called the “Indenture”), among the Issuer, the
Guarantors named therein and Wells Fargo Bank, N.A., as trustee (herein called the “Trustee”), to
which Indenture and all indentures supplemental thereto reference is hereby made for a description
of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee,
the Issuer and the holders of the Notes. Capitalized terms used but not otherwise defined in this
Note shall have the respective meanings ascribed thereto in the Indenture.

The Issuer shall not have the right to redeem the Notes prior to April 20, 2012, except to
preserve its status as a real estate investment trust. If the Issuer determines it is necessary to
redeem the Notes in order to preserve its status as a real estate investment trust, the Issuer may
redeem the Notes for cash, in whole or in part, at a redemption price equal to 100% of the
principal amount of the Notes to be redeemed plus unpaid interest, if any, accrued thereon to, but
excluding, the Redemption Date. At any time on or after April 20, 2012, the Notes may be redeemed
at the option of the Issuer, in whole or in part, in cash at a redemption price equal to 100% of
the principal amount of Notes to be redeemed plus accrued and unpaid interest accrued thereon to,
but excluding, the Redemption Date. If an Interest Payment Date falls on or prior to the Redemption
Date, then the interest payable on such Interest Payment Date shall be paid to the holders of
record of the Notes on the applicable Record Date instead of the holders surrendering the Notes for
redemption.

Subject to the terms and conditions set forth in the Indenture, following the occurrence of a
Change in Control at any time prior to April 20, 2012, the Notes shall be subject to repurchase by
the Issuer, at the option of the holder, on the Change in Control Repurchase Date, at a repurchase
price equal to 100% of the principal amount of the Notes to be repurchased together with accrued
and unpaid interest accrued thereon to, but excluding, the Change in Control Repurchase Date;
provided that if an Interest Payment Date falls on or prior to the Change in Control Repurchase
Date, then, with respect to any Note in respect of which the holder thereof shall have submitted a
Change in Control Repurchase Notice, the interest payable on such Interest Payment Date shall be
paid to the holder of record of such Note on the applicable Record Date instead of the holder
surrendering such Note for repurchase. To exercise such right, the holder shall be required to
satisfy the conditions to such repurchase set forth in the Indenture and to deliver to the Paying
Agent the Change in Control Purchase Notice set forth on the reverse hereof prior to the close of
business on the third Business Day prior to the Change in Control Repurchase Date.

Subject to the terms and conditions of the Indenture, each holder shall have the right, at
such holder’s option, to require the Issuer to repurchase all or any portion of the Notes held by
such holder, on April 15, 2012, April 15, 2017 and April 15, 2022, at a repurchase price equal to
100% of the principal amount of the Notes to be repurchased together with any accrued and unpaid
interest accrued thereon to, but excluding, the Optional Repurchase Date; provided that if an
Interest Payment Date falls on or prior to an Optional Repurchase Date, then, with respect to any
Note in respect of which the holder thereof shall have submitted an Optional Repurchase Notice, the
interest payable on such Interest Payment Date shall be paid to the holder of record of such Note
on the applicable Record Date instead of the holder surrendering such Note for repurchase. To
exercise such right, the holder shall be required to satisfy the conditions to such repurchase set
forth in the Indenture and deliver to the Paying Agent the Optional Repurchase Notice set forth on
the reverse hereof, at any time from the opening of business on the date that is thirty (30)
Business Days prior to the applicable Optional Repurchase Date until the close of business on the
third Business Day prior to the applicable Optional Repurchase Date.

The Issuer may not repurchase any Notes if there has occurred and is continuing an Event of
Default with respect to the Notes (other than a default in the payment of the repurchase price for
such Notes).

Holders have the right to withdraw any Repurchase Notice or an Optional Repurchase Notice, as
applicable, by delivering to the Paying Agent a written notice of withdrawal at any time prior to
the close of business on the third Business Day prior to the Change in Control Repurchase Date or
Optional Repurchase Date, as the case may be, all as provided in the Indenture.

Subject to and in compliance with the provisions of the Indenture, holders of Notes shall have
the right to convert each $1,000 principal amount of Notes at the applicable Conversion Rate into
the consideration specified in the Indenture, upon surrender of the Note to be converted with the
form entitled “Conversion Notice” on the reverse hereof duly completed and manually signed, to the
Issuer at the office or agency of the Issuer maintained for that purpose in accordance with the
terms of the Indenture, together with any funds required pursuant to the terms of the Indenture.
The Conversion Rate shall initially be 28.6874 Common Shares per $1,000 principal amount of Notes,
subject to adjustment in the manner set forth in the Indenture.

Notes surrendered for conversion at any time after the close of business on any applicable
Record Date for the payment of interest and on or prior to the corresponding Interest Payment Date
must be accompanied by payment, in immediately available funds or other funds acceptable to the
Issuer, of an amount equal to the interest otherwise payable on such Interest Payment Date on the
principal amount being converted; provided that no such payment shall be required (1) if the
Issuer has specified a Redemption Date that is after a Record Date and on or prior to the
corresponding Interest Payment Date or (2) to the extent of any overdue interest and Additional
Interest and Special Interest, if any overdue interest and Additional Interest and Special
Interest, as applicable, exists at the time of conversion with respect to such Notes.

In the event the holder surrenders this Note for conversion in connection with a Change in
Control resulting from a transaction described in clause (1) or (2) of the definition of such term,
the Issuer shall increase the applicable Conversion Rate in accordance with the provisions of
Section 13.13 of the Indenture.

In the event that Common Shares are issued upon conversion of Notes, no fractional shares
shall be issued upon such conversion, but an adjustment and payment in cash will be made, as
provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable
upon such conversion.

A Note in respect of which a holder has submitted a Change in Control Purchase Notice or an
Optional Repurchase Notice may be converted only if such holder validly withdraws such Change in
Control Purchase Notice or Optional Repurchase Notice in accordance with the terms of the
Indenture.

If an Event of Default (other than an Event of Default specified in Section 6.01(i), 6.01(j)
and 6.01(k) of the Indenture with respect to the Issuer) shall occur and be continuing, the
principal of, and accrued and unpaid interest on, the Notes may be declared to be due and payable
in the manner specified in the Indenture. If an Event of Default specified in Section 6.01(i),
6.01(j) or 6.01(k) of the Indenture shall occur with respect to the Issuer, the principal of, and
interest accrued and unpaid on, the Notes shall be immediately and automatically due and payable
without necessity of further action. Subject to the provisions of the Indenture, the holders of not
less than a majority in aggregate principal amount of the Notes at the time outstanding may, on
behalf of the holders of all of the Notes, waive any past default or Event of Default, subject to
exceptions set forth in the Indenture. Upon any such waiver, said default shall for all purposes
of this Note and the Indenture be deemed to have been cured and to be not continuing, but no such
waiver shall extend to any subsequent or other default or impair any right consequent thereon.

Notwithstanding the previous paragraph, to the extent elected by the Issuer, the sole remedy
for an Event of Default relating to the failure to comply with the reporting obligations under
Section 5.04 of the Indenture or for any failure to comply with the requirements of
Section 314(a)(1) of the Trust Indenture Act, will for the first 365 days after the occurrence of
such an Event of Default consist exclusively of the right to receive special interest on the Notes
at an annual rate equal to 0.50% of the principal amount of the Notes, in the manner and with the
effect provided in the Indenture.

The Indenture contains provisions permitting the Issuer, the Guarantors and the Trustee, with
the consent of the holders of not less than a majority in aggregate principal amount of the Notes
at the time outstanding, to execute supplemental indentures to modify provisions of the Indenture,
subject to exceptions permitting the modification of the Indenture without the consent of any
holder of Notes or requiring the consent of each holder of a Note affected by such modification all
as set forth in Article 9 of the Indenture.

The Notes are issuable in fully registered form, without coupons, in denominations of $1,000
principal amount and any multiple of $1,000. At the office or agency of the Issuer referred to on
the face hereof, and in the manner and subject to the limitations provided in the Indenture,
without payment of any service charge but with payment of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in connection with any registration or
exchange of Notes, Notes may be exchanged for a like aggregate principal amount of Notes of any
other authorized denominations. Upon surrender for registration of transfer of any Note to the Note
Registrar or any co-registrar, and satisfaction of the requirements for such transfer set forth in
the Indenture, the Issuer shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Notes of any authorized
denominations and of a like aggregate principal amount and bearing such restrictive legends as may
be required by the Indenture. No service charge shall be made to any holder for any registration
of transfer or exchange of Notes, but the Issuer may require payment by the holder of a sum
sufficient to cover any tax, assessment or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Notes.

The Issuer, the Trustee, any Paying Agent, any Conversion Agent and any Note Registrar may
deem the Person in whose name this Note shall be registered upon the Note Register to be, and may
treat it as, the absolute owner of this Note (whether or not this Note shall be overdue and
notwithstanding any notation of ownership or other writing thereon made by any Person other than
the Issuer or any Note Registrar) for the purpose of receiving payment of or on account of the
principal of, and interest on this Note, for conversion of this Note and for all other purposes;
and neither the Issuer or the Trustee nor any Paying Agent, Conversion Agent or any Note Registrar
shall be affected by any notice to the contrary. All such payments so made to any holder for the
time being, or upon its order, shall be valid, and, to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for monies payable upon any this Note.

No recourse for the payment of the principal of or interest on this Note, or for any claim
based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant
or agreement of the Issuer in the Indenture or any supplemental indenture or in any Note, or
because of the creation of any indebtedness represented hereby, shall be had against any
incorporator, shareholder, partner, member, manager, employee, agent, officer, trustee, director or
subsidiary, as such, past, present or future, of the Issuer or any of the Issuer’s Subsidiaries or
of any successor thereto, either directly or through the Issuer or any of the Issuer’s Subsidiaries
or of any successor thereto, whether by virtue of any constitution, statute or rule of law, or by
the enforcement of any assessment or penalty or otherwise; it being expressly understood that all
such liability is hereby expressly waived and released as a condition of, and as consideration for,
the execution of the Indenture and the issue of this Note.

This Note will be entitled to the benefits of the Guarantees made for the benefit of the
holders of Notes under the Indenture. Reference is hereby made to the Indenture for a statement of
the respective rights, limitations of rights, duties and obligations thereunder of the Guarantors,
the Trustee and the holders of the Notes under the Indenture.

In the case of any conflict between the provisions of this Note, the Guarantees and the
Indenture, the provisions of the Indenture shall control. The Indenture, this Note and the
Guarantees shall be governed by, and construed in accordance with, the laws of the state of New
York.

2. Registration Under the Securities Act.

(a) Shelf Registration.

(i) The Company shall file or cause to be filed (or otherwise designate an existing Automatic
Shelf Registration Statement previously filed with the SEC as) a Shelf Registration Statement
providing for the sale by the Holders of all of the Registrable Securities, as promptly as
practicable but in any event on or prior to the Filing Deadline. If the Shelf Registration
Statement is not an Automatic Shelf Registration Statement, the Company shall use its reasonable
best efforts to have such Shelf Registration Statement declared effective by the SEC as promptly as
practicable after filing thereof, but in any event on or prior to the Effectiveness Deadline. If
the Shelf Registration Statement is an Automatic Shelf Registration Statement, the Company shall
use its reasonable best efforts to prepare and file a supplement to the Prospectus to cover resales
of the Registrable Securities by the Holders as promptly as practicable after filing thereof, but
in any event on or prior to the Effectiveness Deadline.

(ii) Notwithstanding any other provision hereof, no Holder of Registrable Securities shall be
entitled to include any of its Registrable Securities in any Shelf Registration Statement pursuant
to this Agreement unless and until such Holder agrees in writing to be bound by all of the
provisions of this Agreement applicable to such Holder and the Holder furnishes to the Company a
fully completed notice and questionnaire in the form attached as Appendix A to the Offering
Memorandum (the “Questionnaire”) and such other information in writing as the Company may
reasonably request in writing for use in connection with the Shelf Registration Statement or
Prospectus included therein and in any application to be filed with or under state securities laws.
The Company shall issue a press release through a reputable national newswire service in relation
to, or otherwise notify Holders of, its filing of (or intention to designate an Automatic Shelf
Registration Statement as) the Shelf Registration Statement and of the anticipated Effective Date
thereof. In order to be named as a selling securityholder in the Prospectus at the time it is
first made available for use, each Holder must furnish the completed Questionnaire and such other
information that the Company may reasonably request in writing, if any, to the Company in writing
no later than the tenth Business Day prior to the anticipated Effective Date as announced in the
press release or such notice. Each Holder as to which any Shelf Registration is being effected
agrees to furnish to the Company all information with respect to such Holder necessary to make the
information previously furnished to the Company by such Holder not materially misleading.

(iii) From and after the Effective Date, upon receipt of a completed Questionnaire and such
other information that the Company may reasonably request in writing, if any, the Company will use
its reasonable best efforts to file as promptly as reasonably practicable but in any event on or
prior to the Filing Deadline either (i) if then permitted by the Securities Act or the rules and
regulations thereunder (or then-current SEC interpretations thereof), a supplement to the
Prospectus naming such Holder as a selling securityholder and containing such other information as
necessary to permit such Holder to deliver the Prospectus to purchasers of the Holder’s Securities,
or (ii) if it is not then permitted under the Securities Act or the rules and regulations
thereunder (or then-current SEC interpretations thereof) to name such Holder as a selling
securityholder in a supplement to the Prospectus, a post-effective amendment to the Shelf
Registration Statement or an additional Shelf Registration Statement as necessary for such Holder
to be named as a selling securityholder in the Prospectus contained therein to permit such Holder
to deliver the Prospectus to purchasers of the Holder’s Securities (subject, in the case of either
clause (i) or clause (ii), to the Company’s right to suspend use of the Shelf Registration
Statement as described in Section 2(a)(iv) hereof). If a post-effective amendment or additional
Shelf Registration Statement is required to be filed, the Company shall use its reasonable best
efforts to have such post-effective amendment or additional Shelf Registration Statement declared
effective by the SEC as promptly as practicable after filing thereof, but in any event on or prior
to the Effectiveness Deadline. The Company shall not be required to file more than three
supplements to the Prospectus, post-effective amendments or additional Shelf Registration
Statements in any fiscal quarter for all such Holders.

(iv) The Company agrees to use its reasonable best efforts to keep the Shelf Registration
Statement continuously effective and the Prospectus usable for resales until there are no Notes or
Registrable Securities outstanding (the “Effectiveness Period”); provided, however, that for
30 days or less (whether or not consecutive) in any three-month period, and for 90 days or less in
any 12-month period, the Company shall be permitted, by giving written notice to the Holders of
Registrable Securities, to suspend sales thereof if the Shelf Registration Statement is no longer
effective or usable for resales due to circumstances relating to pending developments, public
filings with the SEC and similar events, or because the Prospectus contains an untrue statement of
a material fact or omits to state a material fact required to be stated therein or necessary in
order to make statements therein not misleading (any period of suspension hereunder, a “Suspension
Period”). The Company is not required to specify the nature of the event giving rise to the
suspension in its notice to the Holders. If any Shelf Registration Statement ceases to be
effective or usable for resales by Holders for any reason (other than by reason of any such
Holder’s failure to provide a Questionnaire, in which case the provisions of Section 2(a)(ii) or
2(a)(iii) hereof shall apply) at any time during the Effectiveness Period, the Company shall,
subject to the first sentence of this Section 2(a)(iv), use its reasonable best efforts to promptly
cause such Shelf Registration Statement to become effective under the Securities Act, and, shall,
within ten Business Days of such cessation of effectiveness or usability, (i) file with the SEC one
or more supplements to the Prospectus, post-effective amendments or reports under the Exchange Act
in a manner reasonably expected to obtain the withdrawal of any order suspending the effectiveness
of such Shelf Registration Statement, or (ii) file with the SEC an additional Shelf Registration
Statement. If a post-effective amendment or an additional Shelf Registration Statement is filed,
the Company shall use its reasonable best efforts to (A) cause such post-effective amendment or
Shelf Registration Statement to become effective under the Securities Act as promptly as
practicable after such filing, but in no event later than the applicable Effectiveness Deadline,
and (B) keep such post-effective amendment or Shelf Registration Statement continuously effective
until the end of the Effectiveness Period.

(v) If the Shelf Registration Statement is not an Automatic Shelf Registration Statement, the
Company shall not permit any securities other than (i) the Company’s issued and outstanding
securities currently possessing similar registration rights and (ii) the Registrable Securities to
be included in the Shelf Registration. The Company will provide to each Holder named therein a
reasonable number of copies of the Prospectus that is a part of the Shelf Registration Statement,
notify each such Holder of the Effective Date and take such other actions as are required to permit
unrestricted resales of the Registrable Securities by such Holder. The Company further agrees to
supplement or amend the Shelf Registration Statement or supplement the Prospectus if and as
required by the rules, regulations or instructions applicable to the registration form used by the
Company for such Shelf Registration Statement or by the Securities Act or by any other rules and
regulations thereunder for shelf registrations, and the Company agrees to furnish to the Holders of
Registrable Securities copies of any such supplement or amendment promptly after its being used or
filed with the SEC.

(b) Listing. The Company shall use its reasonable best efforts to maintain the approval of
the Common Shares for listing on the New York Stock Exchange.

(c) Expenses. The Company shall pay all Registration Expenses in connection with any Shelf
Registration Statement filed pursuant to Section 2(a) hereof (including the reasonable fees and
disbursements of counsel for the Holders of the Registrable Securities in connection with the
review of any Shelf Registration Statement, Prospectus or amendment or supplement thereto in
accordance with the provisions of Section 3(a) hereof, which counsel shall be reasonably
satisfactory to the Company). Except as provided herein, each Holder shall pay all expenses of its
counsel, underwriting discounts and commissions and transfer taxes, if any, relating to the sale or
disposition of such Holder’s Registrable Securities pursuant to the Shelf Registration Statement.

(d) Effective Shelf Registration Statement. If, after the Effective Date the offering of
Registrable Securities pursuant to a Shelf Registration Statement is interfered with by any stop
order, injunction or other order or requirement of the SEC or any other governmental agency or
court, such Shelf Registration Statement will be deemed not to have been effective during the
period of such interference, until the offering of Registrable Securities pursuant to such Shelf
Registration Statement may legally resume. The Company will be deemed not to have used its
reasonable best efforts to cause a Shelf Registration Statement to become, or to remain, effective
during the requisite period if it voluntarily takes any action that would result in any such Shelf
Registration Statement not being declared effective or that would result in the Holders of
Registrable Securities covered thereby not being able to offer and sell such Registrable Securities
during that period, unless such action is required by applicable law.

(e) Liquidated Damages. In the event that:

(i) a Shelf Registration Statement is not filed with the SEC or designated as such by the
Company on or prior to the Filing Deadline pursuant to Section 2(a)(i), then liquidated damages
(“Liquidated Damages”) shall accrue on the principal amount of the Notes at a rate equal to 0.25%
per annum for the first 90-day period from the day following such Filing Deadline, and thereafter
at a rate per annum of 0.50% of the principal amount of the Notes;

(ii) (x) a Shelf Registration Statement is not declared effective by the SEC, or (y) if the
Company shall have designated a previously filed and effective Automatic Shelf Registration
Statement as the Shelf Registration Statement for purposes of this Agreement, the Company shall not
have filed a supplement to the Prospectus to cover resales of the Registrable Securities by the
Holders, in the case of either (x) or (y), on or prior to the Effectiveness Deadline pursuant to
Section 2(a)(i), then Liquidated Damages shall accrue on the principal amount of the Notes at a
rate equal to 0.25% per annum for the first 90-day period from the day following such Effectiveness
Deadline, and thereafter at a rate per annum of 0.50% of the principal amount of the Notes;

(iii) following the Effective Date, (A) the Company fails to make any filing required pursuant
to Section 2(a)(iii) hereof prior to the Filing Deadline applicable thereto, or (B) in the event
such filing is a post-effective amendment or additional Shelf Registration Statement, such
post-effective amendment or Shelf Registration Statement fails to become effective on or prior to
the Effectiveness Deadline applicable thereto, then Liquidated Damages shall accrue on the
principal amount of the Notes at a rate equal to 0.25% per annum for the first 90-day period from
the day following such Filing Deadline or Effectiveness Deadline, as applicable, and thereafter at
a rate per annum of 0.50% of the principal amount of the Notes;

(iv) following the Effective Date, a Shelf Registration Statement ceases to be effective
(without being succeeded immediately by an additional Shelf Registration Statement that is filed
and immediately becomes effective) or usable for the offer and sale of the Registrable Securities,
other than as a result of a requirement to file a post-effective amendment or supplement to the
Prospectus to make changes to the information regarding selling securityholders or the plan of
distribution provided for therein, and (a) the Company does not cure the lapse of effectiveness or
usability within ten Business Days (or, if a Suspension Period is then in effect, within ten
Business Days following the expiration of such Suspension Period), then Liquidated Damages shall
accrue on the principal amount of the Notes at a rate equal to 0.25% per annum for the first 90-day
period from the day following such tenth Business Day, and thereafter at a rate per annum of 0.50%
of the principal amount of the Notes; or (b) any Suspension Period or Periods exceed 30 days in
any three-month period or 90 days in any 12-month period, then, commencing with the 31st day in
such three-month period or the 91st day in such 12-month period, as the case may be, then
Liquidated Damages shall accrue on the principal amount of the Notes at a rate equal to 0.25% per
annum for the first 90-day period from the day following the 31st or 91st day, as the case may be,
and thereafter at a rate per annum of 0.50% of the principal amount of the Notes; or

(v) if the Company fails to name as a selling securityholder any Holder that had complied
timely with its obligations hereunder in a manner to entitle such Holder to be so named in (A) any
Shelf Registration Statement at the time it first becomes effective or (B) any Prospectus at the
later of time of filing thereof or the time the Shelf Registration Statement of which the
Prospectus forms a part becomes effective, then Liquidated Damages will accrue on the principal
amount of Notes held by such Holder at a rate equal to 0.25% per annum for the first 90-day period
from the day following the effective date of such Shelf Registration Statement or the time of
filing of such Prospectus, as the case may be, and thereafter at a rate per annum of 0.50% of the
principal amount of the Notes held by such Holder;

provided, however, that in no event shall Liquidated Damages accrue at a rate per annum exceeding
0.50% of the principal amount of the Notes; and provided further that Liquidated Damages on the
principal amount of the Notes as a result thereof shall cease to accrue:

(1) upon the filing or designation of a Shelf Registration Statement (in the case of clause
(i) above);

(2) upon the Effective Date (in the case of clause (ii) above);

(3) upon the filing of a supplement to the Prospectus (in the case of clause (iii)(A) above)
or upon the Effective Date (in the case of clause (iii)(B) above);

(4) upon such time as the Shelf Registration Statement which had ceased to remain effective or
usable for resales again becomes effective and usable for resales (in the case of clause
(iv)(a) above);

(5) upon such time as the Shelf Registration Statement which had ceased to remain effective or
usable for resales again becomes effective and usable for resales (in the case of clause
(iv)(b) above); or

(6) upon the time such Holder is permitted to sell its Registrable Securities pursuant to any
Shelf Registration Statement and Prospectus in accordance with applicable law (in the case of
clause (v) above).

Any amounts of Liquidated Damages due pursuant to this Section 2(e) will be payable in cash on
the next succeeding interest payment date to Holders entitled to receive such Liquidated Damages on
the relevant record dates for the payment of interest.

Notwithstanding any provision in this Agreement, in no event shall Liquidated Damages accrue
to holders of shares of Common Stock issued upon conversion of Notes. If any Note ceases to be
outstanding during any period for which Liquidated Damages are accruing, the Company will prorate
the Liquidated Damages payable with respect to such Note.

(f) Specific Enforcement. Without limiting the remedies available to the Holders, the Company
acknowledges that any failure by it to comply with its obligations under Section 2(a) hereof may
result in material irreparable injury to the Holders for which there is no adequate remedy at law,
that it would not be possible to measure damages for such injuries precisely and that, in the event
of any such failure, any Holder may obtain such relief as may be required to specifically enforce
the Company’s obligations under Section 2(a) hereof.

(g) Certain Representations and Agreements of the Company. The Company represents and agrees
that, unless it obtains the prior consent of the Holders of a majority of the Registrable
Securities that are registered under the Shelf Registration Statement at such time or the approval
of the counsel for the holders of Registrable Securities or the consent of the Initial Purchaser in
connection with any underwritten offering of Registrable Securities, and each Holder represents and
agrees that, unless it obtains the prior consent of the Company and the Initial Purchaser, it will
not make any offer relating to the Registrable Securities that would constitute an “issuer free
writing prospectus,” as defined in Rule 433 (an “Issuer Free Writing Prospectus”), or that would
otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with
the SEC. The Company represents that any Issuer Free Writing Prospectus, when taken together with
the information in the Shelf Registration Statement and the Prospectus, will not include any untrue
statement of a material fact or omit to state any material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made, not misleading.

3. Registration Procedures. In connection with the obligations of the Company with respect to
the Shelf Registration Statement pursuant to Section 2(a) hereof, the Company shall use its
reasonable best efforts to:

(a) prepare and file with the SEC or designate a Shelf Registration Statement as prescribed by
Section 2(a)(i) hereof within the relevant time period specified in Section 2(a)(i) hereof on the
appropriate form under the Securities Act, which form shall (i) be selected by the Company, (ii) be
available for the sale of the Registrable Securities by the selling Holders thereof, and
(iii) comply as to form in all material respects with the requirements of the applicable form and
include all financial statements required by the SEC to be filed therewith; the Company shall use
its reasonable best efforts to cause such Shelf Registration Statement to become effective and
remain effective and the Prospectus usable for resales in accordance with Section 2 hereof;
provided, however, that, before filing any Shelf Registration Statement or Prospectus or any
amendments or supplements thereto, the Company shall furnish to and afford in an electronic
transmission the Holders of the Registrable Securities covered by such Shelf Registration
Statement, their counsel and the managing underwriters, if any, a reasonable opportunity to review
copies of all such documents (including copies of any documents to be incorporated by reference
therein and all exhibits thereto) proposed to be filed; and the Company shall not file any Shelf
Registration Statement or Prospectus or any amendments or supplements thereto in respect of which
the Holders must be afforded an opportunity to review prior to the filing of such document if the
Majority Holders, their counsel or the managing underwriters, if any, shall reasonably object in a
timely manner;

(b) prepare and file with the SEC such amendments and post-effective amendments to the Shelf
Registration Statement as may be necessary to keep such Shelf Registration Statement effective for
the Effectiveness Period, and cause each Prospectus to be supplemented, if so determined by the
Company or requested by the SEC, by any required prospectus supplement and as so supplemented to be
filed pursuant to Rule 424 (or any similar provisions then in force) under the Securities Act, and
comply with the provisions of the Securities Act, the Exchange Act and the rules and regulations
promulgated thereunder applicable to it with respect to the disposition of all securities covered
by a Shelf Registration Statement during the Effectiveness Period in accordance with the intended
method or methods of distribution by the selling Holders thereof described in this Agreement;

(c) (i) furnish to each Holder of Registrable Securities included in the Shelf Registration
Statement and to each underwriter of an underwritten offering of Registrable Securities, if any,

reasonably request, in order to facilitate the public sale or other disposition of the Registrable
Securities and (ii) consent to the use of the Prospectus or any amendment or supplement thereto by
each of the selling Holders of Registrable Securities included in the Shelf Registration Statement
in connection with the offering and sale of the Registrable Securities covered by the Prospectus or
any amendment or supplement thereto in accordance with applicable law;

(d) register or qualify the Registrable Securities under all applicable state securities or
“blue sky” laws of such jurisdictions by the time the applicable Shelf Registration Statement has
become effective under the Securities Act as any Holder of Registrable Securities covered by a
Shelf Registration Statement and each underwriter of an underwritten offering of Registrable
Securities shall reasonably request in writing in advance of such date of effectiveness, and do any
and all other acts and things which may be reasonably necessary or advisable to enable such Holder
and underwriter to consummate the disposition in each such jurisdiction of such Registrable
Securities owned by such Holder; provided, however, that the Company shall not be required to
(i) qualify as a foreign entity or as a dealer in securities in any jurisdiction where it would not
otherwise be required to qualify but for this Section 3(d), (ii) file any general consent to
service of process in any jurisdiction where it would not otherwise be subject to such service of
process or (iii) subject itself to taxation in any such jurisdiction if it is not then so subject;

a Shelf Registration Statement or Prospectus or for additional information after the Shelf
Registration Statement has become effective, (iii) of the issuance by the SEC or any state

Statement or the qualification of the Registrable Securities in any jurisdiction described in
Section 3(d) hereof or the initiation of any proceedings for that purpose, (iv) if, between the
Effective Date and the closing of any sale of Registrable Securities covered thereby, any of the
representations and warranties of the Company contained in any purchase agreement, securities sales
agreement or other similar agreement entered into after the date hereof in relation to the sale of
the Registrable Securities cease to be true and correct in all material respects, (v) of the
happening of any event or the failure of any event to occur or the discovery of any facts, during
the Effectiveness Period, which makes any statement made in a Shelf Registration Statement or the
related Prospectus untrue in any material respect or which causes such Shelf Registration Statement
or Prospectus to omit to state a material fact necessary in order to make the statements therein,
in the light of the circumstances under which they were made, not misleading, and (vi) of the
reasonable determination of the Company that a post-effective amendment to the Shelf Registration
Statement would be appropriate;

(f) obtain the withdrawal of any order suspending the effectiveness of the Shelf Registration
Statement at the earliest possible moment;

(g) if requested, furnish to each Holder of Registrable Securities included within the
coverage of a Shelf Registration Statement, without charge, at least one conformed copy of the
Shelf Registration Statement relating to such Shelf Registration and any post-effective amendment
thereto (without documents incorporated therein by reference or exhibits thereto, unless
requested);

(h) cooperate with the selling Holders of Registrable Securities to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to be sold and not

Registrable Securities pursuant to the Shelf Registration Statement;

3(e)(v) (subject to the respective grace periods set forth in Section 2(a)(iv)) or 3(e)(vi) hereof,
prepare a supplement or post-effective amendment to the Shelf Registration Statement or the related
Prospectus or any document incorporated therein by reference or file any other required document so
that, as thereafter delivered to the purchasers of the Registrable Securities, such Prospectus will
not include any untrue statement of a material fact or omit to state a material fact necessary to
make the statements therein, in the light of the circumstances under which they were made, not
misleading; and the Company shall notify each Holder to suspend use of the Prospectus as promptly
as practicable after the occurrence of such an event, and each Holder hereby agrees to suspend use
of the Prospectus until the Company has amended or supplemented the Prospectus to correct such
misstatement or omission;

(j) subject to Section 5 hereof, enter into such agreements (including underwriting
agreements) as are customary in underwritten offerings and take all such other appropriate actions
in connection therewith as are reasonably requested by the Holders collectively holding at least
25% in aggregate principal amount or number, as the context requires, of the Registrable Securities
in order to expedite or facilitate the registration or the disposition of the Registrable
Securities;

(k) whether or not an underwriting agreement is entered into and whether or not the
registration is an underwritten registration, if requested by (x) any Initial Purchaser, in the
case where such Initial Purchaser holds Securities acquired by it as part of its initial placement
and (y) Holders collectively holding at least 25% in aggregate principal amount or number, as the
context requires, of the Registrable Securities covered thereby: (i) make such representations and
warranties to Holders of such Registrable Securities and the underwriters (if any), with respect to
the business of the Company and its subsidiaries as then conducted and with respect to the Shelf

by reference therein, in each case, as are customarily made by issuers to underwriters in
underwritten offerings, and confirm the same if and when requested; (ii) obtain opinions of counsel
to the Company and updates thereof (which may be in the form of a reliance letter) in form and
substance reasonably satisfactory to the managing underwriters (if any) and the Holders
collectively holding a majority in aggregate principal amount or number, as the context requires,
of the Registrable Securities being sold, addressed to each selling Holder and the underwriters (if
any) covering the matters customarily covered in opinions requested in underwritten offerings and
such other matters as may be reasonably requested by such underwriters (it being agreed that the
matters to be covered by such opinion may be subject to customary qualifications and exceptions);
(iii) obtain “cold comfort” letters and updates thereof in form and substance reasonably
satisfactory to the managing underwriters from the independent certified public accountants of the
Company (and, if necessary, any other independent certified public accountants of any business

be, included in the Registration Statement), addressed to each of the underwriters, such letters to
be in customary form and covering matters of the type customarily covered in “cold comfort” letters
in connection with underwritten offerings and such other matters as reasonably requested by such
underwriters in accordance with Statement on Auditing Standards No. 72; and (iv) if an underwriting
agreement is entered into, the same shall contain indemnification provisions and procedures no less
favorable than those set forth in Section 4 hereof (or such other provisions and procedures
acceptable to Holders collectively holding a majority in aggregate principal amount or number, as
the context requires, of Registrable Securities covered by such Shelf Registration Statement and
the managing underwriters) customary for such agreements with respect to all parties to be
indemnified pursuant to said Section (including, without limitation, such underwriters and selling
Holders); and in the case of an underwritten registration, the above requirements shall be
satisfied at each closing under the related underwriting agreement or as and to the extent required
thereunder;

(l) make reasonably available for inspection by any selling Holder of Registrable Securities
who certifies to the Company that it has a current intention to sell Registrable Securities

selling Holder or underwriter (collectively, the “Inspectors”), at the offices where normally kept,
during the Company’s normal business hours, all financial and other records, pertinent
organizational and operational documents and properties of the Company and its subsidiaries

applicable due diligence responsibilities, and cause the officers, trustees and employees of the
Company and its subsidiaries to supply all relevant information in each case reasonably requested
by any such Inspector in connection with such Shelf Registration Statement; Records and information
which the Company, in good faith, deems to be confidential and any Records and information which it
notifies the Inspectors are confidential shall not be disclosed to any Inspector except where
(i) the disclosure of such Records or information is necessary to avoid or correct a material

made generally available to the public through no fault of an Inspector or a selling Holder and to
take such actions as are reasonably necessary to protect the confidentiality of such information;
and each selling Holder of such Registrable Securities will be required to further agree in writing
that it will, upon learning that disclosure of such Records or information is sought in a court of
competent jurisdiction, or in connection with any action, suit or proceeding, give notice to the

(or any similar rule promulgated under the Securities Act) no later than 45 days after the end of
any twelve-month period (or 90 days after the end of any twelve-month period if such period is a
fiscal year) (i) commencing at the end of any fiscal quarter in which Registrable Securities are
sold to underwriters in a firm commitment or best efforts underwritten offering and (ii) if not
sold to underwriters in such an offering, commencing on the first day of the first fiscal quarter
of the Company after the Effective Date, which statements shall cover said twelve-month periods,
provided that the obligations under this Section 3(m) shall be satisfied by the timely filing of
quarterly and annual reports on Forms 10-Q and 10-K under the Exchange Act;

(n) cooperate with each seller of Registrable Securities covered by a Shelf Registration
Statement and each underwriter, if any, participating in the disposition of such Registrable
Securities and its respective counsel in connection with any filings required to be made with the
NASD;

(o) take all other steps necessary to effect the registration of the Registrable Securities
covered by a Shelf Registration Statement contemplated hereby; and

(p) the Company may require each seller of Registrable Securities as to which any registration
is being effected to furnish to it such information regarding such seller as may be required by the
staff of the SEC to be included in a Shelf Registration Statement; the Company may exclude from
such registration the Registrable Securities of any seller who unreasonably fails to furnish such
information within a reasonable time after receiving such request; and the Company shall have no
obligation to register under the Securities Act the Registrable Securities of a seller who so fails
to furnish such information.

Each Holder agrees that, upon receipt of any notice from the Company of the occurrence of any
event specified in Section 3(e)(ii), 3(e)(iii), 3(e)(v) or 3(e)(vi) hereof, such Holder will
forthwith discontinue disposition of Registrable Securities pursuant to a Shelf Registration
Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 3(i) hereof or until it is advised in writing (the “Advice”) by the Company
that the use of the applicable Prospectus may be resumed, and, if so directed by the Company, such
Holder will deliver to the Company (at its expense) all copies in such Holder’s possession, other
than permanent file copies then in such Holder’s possession, of the Prospectus covering such
Registrable Securities current at the time of receipt of such notice. If the Company shall give
any such notice to suspend the disposition of Registrable Securities pursuant to a Shelf
Registration Statement, the Company shall use its reasonable best efforts to file and have declared
effective (if an amendment) as soon as practicable after the resolution of the related matters an
amendment or supplement to the Shelf Registration Statement and related Prospectus.

4. Indemnification and Contribution. (a) The Company hereby agrees to indemnify and hold
harmless the Initial Purchaser, each Holder, each underwriter who participates in an offering of
the Registrable Securities, each Person, if any, who controls any of such parties within the
meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act and each of their
trustees, officers, employees and agents, as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred,
arising out of any untrue statement or alleged untrue statement of a material fact contained in a
Shelf Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or
supplement thereto) or the omission or alleged omission therefrom of a material fact required to be
stated therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred,
to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or
proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever
based upon any such untrue statement or omission, or any such alleged untrue statement or omission,
provided that (subject to Section 4(d) hereof) such settlement is effected with the written consent
of the Company; and

(iii) against any and all expenses whatsoever, as incurred (including, without limitation, the
reasonable fees and disbursements of counsel chosen by the Initial Purchaser or such Holder),
reasonably incurred in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or threatened, or any
claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue
statement or omission, to the extent that any such expense is not paid under subparagraph (i) or
(ii) of this Section 4(a);

provided, however, that this indemnity does not apply to any loss, liability, claim, damage or
expense to the extent arising out of an untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with written information furnished in writing to
the Company by the Initial Purchaser or such Holder or underwriter expressly for use in the Shelf
Registration Statement (or any amendment thereto) or any Prospectus (or any amendment or supplement
thereto) and does not apply if the untrue statement or omission was corrected in a prospectus
supplement or free writing prospectus delivered to the person asserting such loss or claim prior to
the earlier of the applicable contract of sale or time of sale.

(b) The Initial Purchaser and each Holder or underwriter, severally and not jointly, agrees to
indemnify and hold harmless the Company, its trustees and officers (including each officer of the
Company who signed the Shelf Registration Statement), and each Person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act
against any and all loss, liability, claim, damage and expense whatsoever described in the
indemnity contained in Section 4(a) hereof, as incurred, but only with respect to untrue statements
or omissions, or alleged untrue statements or omissions, made in the Shelf Registration Statement
(or any amendment thereto) or the Prospectus (or any amendment or supplement thereto) in reliance
upon and in conformity with written information furnished to the Company by such Holder expressly
for use in such Shelf Registration Statement (or any amendment thereto) or such Prospectus (or any
amendment or supplement thereto); provided, however, that no Holder shall be liable for any claims
hereunder in excess of the amount of net proceeds received by such Holder from the sale of
Registrable Securities.

(c) Each indemnified party shall give notice as promptly as reasonably practicable to each
indemnifying party of any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party
from any liability which it may have under this Section 4 to the extent that it is not materially
prejudiced by such failure as a result thereof, and in any event shall not relieve it from
liability which it may have otherwise on account of this indemnity agreement. The indemnifying
party shall assume the defense of such action, including the employment of counsel and payment of
expenses; provided, however, that any failure or delay to so notify the indemnifying party will not
relieve the indemnifying party of any obligation hereunder, except to the extent that its ability
to defend is materially impaired by such failure or delay. The indemnified party or such
controlling person shall have the right to employ its or their own counsel in any such case, but
the fees and expenses of such counsel shall be at the expense of the indemnified party or such
controlling person unless the employment of such counsel shall have been authorized in writing by
the indemnifying party in connection with the defense of such action, or the indemnifying party
shall not have employed counsel to have charge of the defense of such action within a reasonable
time or such indemnified party or parties shall have reasonably concluded (based on the advice of
counsel) that there may be defenses available to it or them which are different from or additional
to those available to the indemnifying party (in which case the indemnifying party shall not have
the right to direct the defense of such action on behalf of the indemnified party or parties), in
any of which events such fees and expenses shall be borne by the indemnifying party and paid as
incurred (it being understood, however, that the indemnifying party shall not be liable for the
expenses of more than one separate firm of attorneys for the indemnified party or controlling
persons in any one action or series of related actions in the same jurisdiction (other than local
counsel in any such jurisdiction) representing the indemnified parties who are parties to such
action). No indemnifying party shall, without the prior written consent of the indemnified
parties, settle or compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever in respect of which indemnification or contribution could be
sought under this Section 4 (whether or not the indemnified parties are actual or potential parties
thereto), unless (x) such settlement, compromise or consent (i) includes an unconditional written
release of each indemnified party from all liability arising out of such litigation, investigation,
proceeding or claim and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act by or on behalf of any indemnified party and (y) the indemnifying
part confirms in writing its indemnification obligations hereunder with respect to such settlement,
compromise or judgment.

(d) In order to provide for just and equitable contribution in circumstances in which the
indemnity agreement set forth in this Section 4 is for any reason held to be unenforceable by an
indemnified party although applicable in accordance with its terms, the Company, on the one hand,
and the Holders, on the other hand, shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by such indemnity agreement incurred by the Company
and the Holders, as incurred; provided, however, that no Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person that was not guilty of such fraudulent misrepresentation. As between
the Company, on the one hand, and the Holders, on the other hand, such parties shall contribute to
such aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by such
indemnity agreement in such proportion as shall be appropriate to reflect the relative fault of the
Company, on the one hand, and the Holders, on the other hand, with respect to the statements or
omissions which resulted in such loss, liability, claim, damage or expense, or action in respect
thereof, as well as any other relevant equitable considerations. The relative fault of the
Company, on the one hand, and of the Holders, on the other hand, shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information supplied by the
Company, on the one hand, or by or on behalf of the Holders, on the other, and the parties’
relative intent, knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company and the Holders of the Registrable Securities agree that it
would not be just and equitable if contribution pursuant to this Section 4 were to be determined by
pro rata allocation or by any other method of allocation that does not take into account the
relevant equitable considerations. For purposes of this Section 4, each Affiliate of a Holder, and
each trustee, officer and employee and Person, if any, who controls a Holder or such Affiliate
within the meaning of Section 15 of the Securities Act shall have the same rights to contribution
as such Holder, and each trustee and officer of the Company and each Person, if any, who controls
the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act shall have the same rights to contribution as the Company.

5. Underwritten Registration; Participation Therein. (a) In no event will the method of
distribution of the Registrable Securities take the form of an underwritten offering without the
prior written consent of the Company. No Holder may participate in an underwritten registration
hereunder unless such Holder (i) agrees to sell such Holder’s Registrable Securities on the basis
provided in the underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements and (ii) completes and executes all reasonable questionnaires, powers of
attorney, indemnities, underwriting agreements, lock-up letters and other documents reasonably
required under the terms of such underwriting arrangements.

(b) Selection of Underwriters. The Holders of Registrable Securities covered by the Shelf
Registration Statement who desire to do so may sell the Securities covered by such Shelf
Registration in an underwritten offering, subject to the provisions of Sections 3(k) and 5(a)
hereof. In any such underwritten offering, the underwriter or underwriters and manager or managers
that will administer the offering will be selected by the Holders of a majority in aggregate
principal amount or number, as the context requires, of the Registrable Securities included in such
offering;  provided, however, that such underwriters and managers must be reasonably satisfactory
to the Company.

6. Miscellaneous.

(a) Rule 144 and Rule 144A. For so long as it is subject to the reporting requirements of
Section 13 or 15 of the Exchange Act and any Registrable Securities remain outstanding, the Company
will file the reports required to be filed by it under the Securities Act and Section 13(a) or
15(d) of the Exchange Act and the rules and regulations adopted by the SEC thereunder; provided,
however, that if the Company ceases to be so required to file such reports, it will, upon the
request of any Holder of Registrable Securities (a) make publicly available such information as is
necessary to permit sales of its securities pursuant to Rule 144 under the Securities Act,
(b) deliver such information to a prospective purchaser as is necessary to permit sales of its
securities pursuant to Rule 144A under the Securities Act, and (c) take such further action that is
reasonable in the circumstances, in each case, to the extent required from time to time to enable
such Holder to sell its Registrable Securities without registration under the Securities Act within
the limitation of the exemptions provided by (i) Rule 144 under the Securities Act, as such rule
may be amended from time to time, (ii) Rule 144A under the Securities Act, as such rule may be
amended from time to time, or (iii) any similar rules or regulations hereafter adopted by the SEC.
Upon the request of any Holder of Registrable Securities, the Company will deliver to such Holder a
written statement as to whether it has complied with such requirements.

(b) No Inconsistent Agreements. The Company has not entered into, and will not enter into,
any agreement which is inconsistent with the rights granted to the Holders of Registrable
Securities in this Agreement or otherwise conflicts with the provisions hereof. The rights granted
to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights
granted to the holders of the Company’s other issued and outstanding securities under any such
agreements.

(c) Amendments and Waivers. The provisions of this Agreement, including the provisions of
this sentence, may not be amended, modified or supplemented, and waivers or consents to departures
from the provisions hereof may not be given, unless the Company has obtained the written consent of
the Holders holding at least a majority in aggregate principal amount or number, as the context
requires, of the Registrable Securities outstanding and affected by such amendment, modification,
supplement, waiver or departure; provided that no amendment, modification or supplement or waiver
or consent to the departure with respect to the provisions of Section 4 hereof shall be effective
as against any Holder of Registrable Securities unless consented to in writing by such Holder of
Registrable Securities. Notwithstanding the foregoing sentence, (i) this Agreement may be amended,
without the consent of any Holder of Registrable Securities, by written agreement signed by the
Company and the Initial Purchaser, to cure any ambiguity, correct or supplement any provision of
this Agreement that may be inconsistent with any other provision of this Agreement or to make any
other provisions with respect to matters or questions arising under this Agreement which shall not
be inconsistent with other provisions of this Agreement, (ii) this Agreement may be amended,
modified or supplemented, and waivers and consents to departures from the provisions hereof may be
given, by written agreement signed by the Company and the Initial Purchaser to the extent that any
such amendment, modification, supplement, waiver or consent is, in their reasonable judgment,
necessary or appropriate to comply with applicable law (including any interpretation of the Staff
of the SEC) or any change therein and (iii) to the extent any provision of this Agreement relates
to the Initial Purchaser, such provision may be amended, modified or supplemented, and waivers or
consents to departures from such provisions may be given, by written agreement signed by the
Initial Purchaser and the Company.

(d) Notices. All notices and other communications provided for or permitted hereunder shall
be made in writing by hand-delivery, registered first-class mail, telex, telecopier, or any courier
guaranteeing overnight delivery (i) if to a Holder, at the most current address given by such
Holder to the Company by means of a notice given in accordance with the provisions of this
Section 6(d), which address initially is, with respect to the Initial Purchaser, the Initial
Purchaser’s address set forth in the Purchase Agreement; and (ii) if to the Company, initially at
the Company’s address set forth in the Purchase Agreement and thereafter at such other address,
notice of which is given in accordance with the provisions of this Section 6(d).

All such notices and communications shall be deemed to have been duly given: at the time
delivered by hand, if personally delivered; five Business Days after being deposited in the mail,
postage prepaid, if mailed; when answered back, if telexed; when receipt is acknowledged, if
telecopied; and on the next Business Day, if timely delivered to an air courier guaranteeing
overnight delivery.

(e) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon
the successors, assigns and transferees of the Initial Purchaser, including, without limitation and
without the need for an express assignment, subsequent Holders;  provided, however, that nothing
herein shall be deemed to permit any assignment, transfer or other disposition of Registrable
Securities in violation of the terms of the Purchase Agreement, the Indenture relating to the Notes
or the amended and restated declaration of trust of the Company. If any transferee of any Holder
shall acquire Registrable Securities, in any manner, whether by operation of law or otherwise, such
Registrable Securities shall be held subject to all of the terms of this Agreement, and by taking
and holding such Registrable Securities, such Person shall be conclusively deemed to have agreed to
be bound by and to perform all of the terms and provisions of this Agreement and such Person shall
be entitled to receive the benefits hereof.

(f) Third Party Beneficiaries. Each Holder shall be a third party beneficiary of the
agreements made hereunder between the Company and the Initial Purchaser, and the Initial Purchaser
shall have the right to enforce such agreements directly to the extent it deems such enforcement
necessary or advisable to protect its rights or the rights of Holders hereunder.

(g) Counterparts. This Agreement may be executed in any number of counterparts and by the
parties hereto in separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same agreement.

(h) Headings. The headings in this Agreement are for convenience of reference only and shall
not limit or otherwise affect the meaning hereof.

(i) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK.

(j) Severability. In the event that any one or more of the provisions contained herein, or
the application thereof in any circumstance, is held invalid, illegal or unenforceable, the
validity, legality and enforceability of any such provision in every other respect and of the
remaining provisions contained herein shall not be affected or impaired thereby.

(k) Securities Held by the Company or its Affiliates. Whenever the consent or approval of
Holders of a specified percentage of Registrable Securities is required hereunder, Registrable
Securities held by the Company or any Affiliates shall not be counted in determining whether such
consent or approval was given by the Holders of such required percentage.
