EXHIBIT 10.21

INDEMNIFICATION AGREEMENT

     THIS AGREEMENT is made and entered into this            day of            ,             by and between
TITANIUM ASSET MANAGEMENT CORP., a Delaware corporation (the “Corporation”), and
            (“Agent”).

RECITALS

     WHEREAS, Agent performs a valuable service to the Corporation in his capacity as a
director/officer of the Corporation;

     WHEREAS, the Corporation has adopted provisions in its Certificate of Incorporation (the
“Charter”) and bylaws (the “Bylaws”) providing for the indemnification of the directors, officers,
employees and other agents of the Corporation, including persons serving at the request of the
Corporation in such capacities with other corporations or enterprises, as authorized by the
Delaware General Corporation Law, as amended (the “Code”);

     WHEREAS, the Charter, the Bylaws and the Code, by their non-exclusive nature, permit contracts
between the Corporation and its agents, officers, employees and other agents with respect to
indemnification of such persons; and

     WHEREAS, in order to induce Agent to serve as a director/officer of the Corporation, the
Corporation has determined and agreed to enter into this Agreement with Agent.

     NOW, THEREFORE, in consideration of Agent’s service as a director/officer of the Corporation
after the date hereof, the parties hereto agree as follows:

AGREEMENT

     1. Services to the Corporation. Agent will serve, at the will of the Corporation or under
separate contract, if any such contract exists, as a director/officer of the Corporation or as a
director, officer or other fiduciary of an affiliate of the Corporation (including any employee
benefit plan of the Corporation) faithfully and to the best of his ability so long as he is duly
elected and qualified in accordance with the provisions of the Bylaws or other applicable charter
documents of the Corporation or such affiliate; provided, however, that Agent may
at any time and for any reason resign from such position (subject to any contractual obligation
that Agent may have assumed apart from this Agreement) and that the Corporation or any affiliate
shall have no obligation under this Agreement to continue Agent in any such position.

     2. Indemnity of Agent. The Corporation hereby agrees to hold harmless and indemnify Agent to
the fullest extent authorized or permitted by the provisions of the Charter, the Bylaws and the
Code, as the same may be amended from time to time (but, only to the extent that such amendment
permits the Corporation to provide broader indemnification rights than the Charter, the Bylaws or
the Code permitted prior to adoption of such amendment).

     3. Additional Indemnity. In addition to and not in limitation of the indemnification
otherwise provided for herein, and subject only to the exclusions set forth in Section 4 hereof,
the Corporation hereby further agrees to hold harmless and indemnify Agent:

 

 

          (a) against any and all expenses (including attorneys’ fees), witness fees, damages,
judgments, fines and amounts paid in settlement and any other amounts that Agent becomes legally
obligated to pay because of any claim or claims made against or by him in connection with any
threatened, pending or completed action, suit or proceeding, whether civil, criminal,
arbitrational, administrative or investigative (including an action by or in the right of the
Corporation) to which Agent is, was or at any time, becomes a party or a witness, or is threatened
to be made a party or a witness, by reason of the fact that Agent is, was or at any time becomes a
director, officer, employee or other agent of Corporation, or is or was serving or at any time
serves at the request of the Corporation as a director, officer, employee or other agent of another
corporation, partnership, joint venture, trust, employee benefit plan or other enterprise; and

          (b) otherwise to the fullest extent as may be provided to Agent by the Corporation under the
non-exclusivity provisions of the Code, the Charter and the Bylaws.

     4. Limitations on Additional Indemnity. No indemnity pursuant to Section 3 hereof shall be
paid by the Corporation:

          (a) on account of any claim against Agent for an accounting of profits made from the purchase
or sale by Agent of securities of the Corporation pursuant to the provisions of Section 16(b) of
the Securities Exchange Act of 1934 and amendments thereto or similar provisions of any federal,
state or local statutory law;

          (b) on account of Agent’s conduct that is established by a final judgment as knowingly
fraudulent or deliberately dishonest or that constituted willful misconduct;

          (c) on account of Agent’s conduct that is established by a final judgment as constituting a
breach of Agent’s duty of loyalty to the Corporation or resulting in any personal profit or
advantage to which Agent was not legally entitled;

          (d) for which payment is actually made to Agent under a valid and collectible insurance policy
or under a valid and enforceable indemnity clause, bylaw or agreement, except in respect of any
excess beyond payment under such insurance, clause, bylaw or agreement;

          (e) if indemnification is not lawful (and, in this respect, both the Corporation and Agent
have been advised that the Securities and Exchange Commission believes that indemnification for
liabilities arising under the federal securities laws is against public policy and is, therefore,
unenforceable and that claims for indemnification should be submitted to appropriate courts for
adjudication); or

          (f) in connection with any proceeding (or part thereof) initiated by Agent, or any proceeding
by Agent against the Corporation or its directors, officers, employees or other agents, unless (i)
such indemnification is expressly required to be made by law, (ii) the proceeding was authorized by
the Board of Directors of the Corporation, (iii) such indemnification is provided by the
Corporation, in its sole discretion, pursuant to the powers vested in the Corporation under the
Code, or (iv) the proceeding is initiated pursuant to Section 9 hereof.

 

 

     5. Continuation of Indemnity. All agreements and obligations of the Corporation contained
herein shall continue during the period Agent is a director, officer, employee or other agent of
the Corporation (or is or was serving at the request of the Corporation as a director, officer,
employee or other agent of another corporation, partnership, joint venture, trust, employee benefit
plan or other enterprise) and shall continue thereafter so long as Agent shall be subject to any
possible claim or threatened, pending or completed action, suit or proceeding, whether civil,
criminal, arbitrational, administrative or investigative, by reason of the fact that Agent was
serving in the capacity referred to herein.

     6. Partial Indemnification. Agent shall be entitled under this Agreement to indemnification
by the Corporation for a portion of the expenses (including attorneys’ fees), witness fees,
damages, judgments, fines and amounts paid in settlement and any other amounts that Agent becomes
legally obligated to pay in connection with any action, suit or proceeding referred to in Section 3
hereof even if not entitled hereunder to indemnification for the total amount thereof, and the
Corporation shall indemnify Agent for the portion thereof to which Agent is entitled.

     7. Notification and Defense of Claim. Not later than thirty (30) days after Agent becomes
aware, by written or other overt communication, of any pending or threatened litigation, claim or
assessment, Agent will, if a claim in respect thereof is to be made against the Corporation under
this Agreement, notify the Corporation of such pending or threatened litigation, claim or
assessment; but the omission so to notify the Corporation will not relieve it from any liability
which it may have to Agent otherwise than under this Agreement. With respect to any such pending
or threatened litigation, claim or assessment as to which Agent notifies the Corporation of the
commencement thereof:

          (a) the Corporation will be entitled to participate therein at its own expense;

          (b) except as otherwise provided below, the Corporation may, at its option and jointly with
any other indemnifying party similarly notified and electing to assume such defense, assume the
defense thereof, with counsel reasonably satisfactory to Agent. After notice from the Corporation
to Agent of its election to assume the defense thereof, the Corporation will not be liable to Agent
under this Agreement for any legal or other expenses subsequently incurred by Agent in connection
with the defense thereof except for reasonable costs of investigation or otherwise as provided
below. Agent shall have the right to employ separate counsel in such action, suit or proceeding
but the fees and expenses of such counsel incurred after notice from the Corporation of its
assumption of the defense thereof shall be at the expense of Agent unless (i) the employment of
counsel by Agent has been authorized by the Corporation, (ii) Agent shall have reasonably
concluded, and so notified the Corporation, that there is an actual conflict of interest between
the Corporation and Agent in the conduct of the defense of such action or (iii) the Corporation
shall not in fact have employed counsel to assume the defense of such action, in each of which
cases the fees and expenses of Agent’s separate counsel shall be at the expense of the Corporation.
The Corporation shall not be entitled to assume the defense of any action, suit or proceeding
brought by or on behalf of the Corporation or as to which Agent shall have made the conclusion
provided for in clause (ii) above; and

          (c) the Corporation shall not be liable to indemnify Agent under this Agreement for any
amounts paid in settlement of any action or claim effected without its written

 

 

consent, which shall not be unreasonably withheld. The Corporation shall be permitted to
settle any action or claim except that it shall not settle any action or claim in any manner which
would impose any penalty or limitation on Agent without Agent’s written consent, which may be given
or withheld in Agent’s sole discretion.

     8. Expenses. The Corporation shall advance, prior to the final disposition of any proceeding,
promptly following request therefor, all expenses incurred by Agent in connection with such
proceeding upon receipt of an undertaking by or on behalf of Agent to repay said amounts if it
shall be determined ultimately that Agent is not entitled to be indemnified under the provisions of
this Agreement, the Charter, the Bylaws, the Code or otherwise.

     9. Enforcement. Any right to indemnification or advances granted by this Agreement to Agent
shall be enforceable by or on behalf of Agent in any court of competent jurisdiction if (i) the
claim for indemnification or advances is denied, in whole or in part, or (ii) no disposition of
such claim is made within ninety (90) days of request therefor. Agent, in such enforcement action,
if successful in whole or in part, shall be entitled to be paid also the expense of prosecuting his
claim. It shall be a defense to any action for which a claim for indemnification is made under
Section 3 hereof (other than an action brought to enforce a claim for expenses pursuant to Section
8 hereof, provided that the required undertaking has been tendered to the Corporation) that
Agent is not entitled to indemnification because of the limitations set forth in Section 4 hereof
Neither the failure of the Corporation (including its Board of Directors or its stockholders) to
have made a determination prior to the commencement of such enforcement action that indemnification
of Agent is proper in the circumstances, nor an actual determination by the Corporation (including
its Board of Directors or its stockholders) that such indemnification is improper shall be a
defense to the action or create a presumption that Agent is not entitled to indemnification under
this Agreement or otherwise.

     10. Subrogation. In the event of payment under this Agreement, the Corporation shall be
subrogated to the extent of such payment to all of the rights of recovery of Agent, who shall
execute all documents required and shall do all acts that may be necessary to secure such rights
and to enable the Corporation effectively to bring suit to enforce such rights.

     11. Non-Exclusivity of Rights. The rights conferred on Agent by this Agreement shall not be
exclusive of any other right which Agent may have or hereafter acquire under any statute, provision
of the Corporation’s Certificate of Incorporation or Bylaws, agreement, vote of
stockholders or directors, or otherwise, both as to action in his official capacity and as to
action in another capacity while holding office.

     12. Survival of Rights.

          (a) The, rights conferred on Agent by this Agreement shall continue after Agent has
ceased to be a director, officer, employee or other agent of the Corporation or to serve at the
request of the Corporation as a director, officer, employee or other agent of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise, and shall inure to
the benefit of Agent’s heirs, executors and administrators.

          (b) The Corporation shall require any successor (whether direct or indirect, by purchase,
merger, consolidation or otherwise) to all or substantially all of the business or assets

 

 

of the Corporation, expressly to assume and agree to perform this Agreement in the same manner
and to the same extent that the Corporation would be required to perform if no such succession had
taken place.

     13. Separability. Each of the provisions of this Agreement is a separate and distinct
agreement and independent of the others, so that if any provision hereof shall be held to be
invalid or unenforceable for any reason, such invalidity or unenforceability shall not affect the
validity or enforceability of the other provisions hereof. Furthermore, if this Agreement shall be
invalidated in its entirety on any ground, then the Corporation shall nevertheless indemnify Agent
to the fullest extent provided by the Charter, the Bylaws, the Code or any other applicable law.

     14. Governing Law. This Agreement shall be interpreted and enforced in accordance with the
laws of the State of Delaware.

     15. Amendment and Termination. No amendment, modification, termination or cancellation of
this Agreement shall be effective unless in writing signed by both parties hereto.

     16. Identical Counterparts. This Agreement may be executed in one or more counterparts, each
of which shall for all purposes be deemed to be an original but all of which together shall
constitute but one and the same Agreement. Only one such counterpart need be produced to evidence
the existence of this Agreement.

     17. Headings. The headings of the sections of this Agreement are inserted for convenience
only and shall not be deemed to constitute part of this Agreement or to affect the construction
hereof.

     18. Notices. Any notice, demand or request required or permitted to be given under this
Agreement shall be in writing and shall be deemed sufficient when delivered personally or sent by
fax or 48 hours after being sent by internationally-recognized courier or deposited in the U.S.
mail, as certified or registered mail, with postage prepaid, and addressed to the party to be
notified at such party’s address or fax number as set forth below or as subsequently modified by
written notice.

THE SECURITIES

     Section 2.01. Form and Dating.

     The Securities and the Trustee’s certificate of authentication shall be substantially in the
respective forms set forth in Exhibit A, which Exhibit is incorporated in and made part of this
Indenture. The Securities may include such letters, numbers or other marks of identification and
such notations, legends, endorsements or changes as the Officer 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 Trustee, the Depositary, 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 national securities exchange or automated quotation system on
which the Securities may be listed or quoted, or to conform to usage, or to indicate any special
limitations or restrictions to which any particular Securities are subject. Each Security shall be
dated the date of its authentication.

     (a) Global Securities. All of the Securities initially being offered and sold to the
Initial Purchasers shall be issued in the form of one or more Global Securities, which shall be
deposited on behalf of the purchasers of the Securities represented thereby with The Bank of New
York Mellon, at its Corporate Trust Office, as custodian for the depositary, The Depository Trust
Company (“DTC,” and such depositary, or any successor thereto, being hereinafter referred to as the
“Depositary”), and registered in the name of its nominee, Cede & Co. (or any successor thereto),
for the accounts of participants in the Depositary, duly executed by the Company and authenticated
by the Trustee as hereinafter provided. The aggregate principal amount of the Global Securities
may from time to time be increased or decreased by adjustments made on the records of the
Securities Custodian as hereinafter provided, subject in each case to compliance with the
Applicable Procedures.

     (b) Global Securities in General. The Global Security shall represent such of the
outstanding Securities as shall be specified therein and each shall provide that it shall represent
the aggregate principal amount of outstanding Securities from time to time endorsed thereon and
that the aggregate principal amount of outstanding Securities represented thereby may from time to
time be reduced or increased, as appropriate, to reflect exchanges, purchases or conversions of
such Securities.

11

 

     Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under
this Indenture with respect to any Global Security held on their behalf by the Depositary or under
the Global Security, and the Depositary (including, for this purpose, its nominee) may be treated
by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and
Holder of such Global Security for all purposes whatsoever. None of the Trustee, the Paying Agent
or any Registrar shall have any responsibility or obligation to any beneficial owner in a Global
Security, an Agent Member or other Person with respect to the accuracy of the records of the
Depositary or its nominee or of any Agent Member, with respect to any ownership interest in the
Securities or with respect to the delivery to any Agent Member, beneficial owner 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 Securities. All notices and communications to be given
to the Holders and all payments to be made to Holders under the Securities and this Indenture shall
be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of the Global Security). The rights of
beneficial owners in a Global Security shall be exercised only through the Depositary subject to
the Applicable Procedures. The Trustee, the Paying Agent and each Registrar shall be entitled to
rely and shall be fully protected in relying upon information furnished by the Depositary with
respect to its members, participants and any beneficial owners. The Trustee, the Paying Agent and
each Registrar shall be entitled to deal with the Depositary, and any nominee thereof, that is the
registered Holder of any Global Security for all purposes of this Indenture relating to such Global
Security (including the payment of principal, premium, if any, and interest and additional amounts,
if any, and the giving of instructions or directions by or to the owner or Holder of a beneficial
ownership interest in such Global Security) as the sole Holder of such Global Security and shall
have no obligations to the beneficial owners thereof. None of the Trustee, the Paying Agent or any
Registrar shall have any responsibility or liability for any acts or omissions of the Depositary
with respect to such Global Security, for the records of any such depositary, including records in
respect of beneficial ownership interests in respect of any such Global Security, for any
transactions between the Depositary and any Agent Member or between or among the Depositary, any
such Agent Member and/or any Holder or owner of a beneficial interest in such Global Security, or
for any transfers of beneficial interests in any such Global Security.

     Notwithstanding the foregoing, nothing herein shall (1) prevent the Company, the Trustee or
any agent of the Company or the Trustee from giving effect to any written certification, proxy or
other authorization furnished by the Depositary or (2) impair, as between the Depositary and its
Agent Members, the operation of customary practices governing the exercise of the rights of a
Holder of any Security.

     (c) Book Entry Provisions. The Company shall execute and the Trustee shall, in
accordance with this Section 2.01(c), authenticate and deliver initially one or more Global
Securities that (1) shall be registered in the name of the Depositary or its nominee, (2) shall be
delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions and (3)
shall bear legends substantially to the following effect:

     “UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY
TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT,
AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS
IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY
PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN
AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER
USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER
HEREOF, CEDE & CO., HAS

12

 

AN INTEREST HEREIN. THIS SECURITY IS A GLOBAL SECURITY WITHIN THE
MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A
DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN
THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED
CIRCUMSTANCES DESCRIBED IN THE INDENTURE AND, UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR
IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A
WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO
THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE
TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.”

     Section 2.02. Execution and Authentication.

     (a) The aggregate principal amount of Securities which may be authenticated and delivered
under this Indenture is limited to $575,000,000 aggregate principal amount, except as provided in
Sections 2.07, 2.08, 2.11 and 2.18.

     (b) The Securities shall be executed on behalf of the Company by one of its Officers. The
signatures of any of the Officers on the Securities may be manual or facsimile.

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

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

     (e) The Trustee shall authenticate and make available for delivery Securities for original
issue in the aggregate principal amount of $575,000,000 upon receipt of a Company Order. The
Company Order shall specify the amount of Securities to be authenticated, shall provide that all
such Securities will be represented by a Global Security and the date on which each original issue
of Securities is to be authenticated.

     (f) The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may
appoint an authenticating agent acceptable to the Company to authenticate Securities. An
authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in
this Indenture to authentication by the Trustee includes authentication by such agent. An
authenticating agent shall have the same rights as an Agent to deal with the Company or an
Affiliate of the Company.

     (g) The Securities shall be issuable only in registered form without coupons and only in
minimum denominations of $1,000 principal amount and any integral multiple thereof.

13

 

     Section 2.03. Registrar and Paying Agent.

     (a) The Company shall maintain one or more offices or agencies where Securities may be
presented for registration of transfer or for exchange (each, a “Registrar”), one or more offices
or agencies where Securities may be presented or surrendered for payment, including upon cash
conversion (each, a “Paying Agent”) and one or more offices or agencies where notices and demands
to or upon the Company in respect of the Securities and this Indenture may be served. The Company
will at all times maintain a Paying Agent, Registrar and an office or agency where notices and
demands to or upon the Company in respect of the Securities and this Indenture may be served in the
Borough of Manhattan, The City of New York. One of the Registrars (the “Primary Registrar”) shall
keep a register of the Securities (the “Security Register”) and of their transfer and exchange. At
the option of the Company, any payment of cash may be made by check mailed to the Holders at their
addresses set forth in the register of Holders.

     (b) The Company shall enter into an appropriate agency agreement with any Agent not a party to
this Indenture, provided that the Agent may be an Affiliate of the Trustee. The agreement shall
implement the provisions of this Indenture that relate to such Agent. The Company shall
notify the Trustee of the name and address, and any change in the name or address, of any Agent not
a party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent or agent for
service of notices and demands in any place required by this Indenture, or fails to give the
foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company may
act as Paying Agent (except for the purposes of Article 9).

     (c) The Company hereby initially designates The Bank of New York Mellon as Paying Agent,
Primary Registrar and Securities Custodian, and designates the Corporate Trust Office of the
Trustee as the office or agency of the Company for each of the aforesaid purposes and as the office
or agency where notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served.

     Section 2.04. Paying Agent To Hold Money in Trust.

     Unless otherwise specified herein, prior to 10:00 a.m., New York City time, on each due date
of the payment of principal of, interest on, or the Conversion Reference Value with respect to, the
Securities, the Company shall deposit a sum sufficient to pay such principal, interest or
Conversion Reference Value so becoming due. A Paying Agent shall hold in trust for the benefit of
Holders of Securities or the Trustee all money held by the Paying Agent for the payment of
principal of, interest on, or the Conversion Reference Value with respect to, the Securities, and
shall notify the Trustee of any failure by the Company (or any other obligor on the Securities) to
make any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it
shall, before 10:00 a.m., New York City time, on each due date of the principal of, interest on, or
the Conversion Reference Value with respect to, any Securities, segregate the money and hold it as
a separate trust fund for the benefit of the applicable Holders. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee, and the Trustee may at any time
during the continuance of any Default, upon written request to a Paying Agent, require such Paying
Agent to pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing
so, the Paying Agent (other than the Company) shall have no further liability for the money.

     Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of, interest on, or the Conversion Reference Value with
respect to, any Security and remaining unclaimed for two years after such principal, interest or
Conversion Reference Value has become due and payable shall promptly be paid to the Company or (if
then held by the Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an un-

14

 

secured general creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment, may at the expense
of the Company cause to be published once, in a newspaper published in the English language,
customarily published on each Business Day and of general circulation in The City of New York,
notice that such money remains unclaimed and that, after a date specified therein, which shall not
be less than 30 days from the date of such publication, any unclaimed balance of such money then
remaining will promptly be repaid to the Company.

     Section 2.05. [Reserved].

     
Section 2.06. Lists of Holders of Securities.

     The Trustee shall preserve in as current a form as is reasonably practicable the most recent
list available to it of the names and addresses of Holders of Securities. The Company shall
furnish or cause the Registrar to furnish to the Trustee (a) semiannually, not more than 10 days
after each Regular Record Date, a list, in such form as the Trustee may reasonably require, of the names and addresses
of the Holders as of such Regular Record Date; and (b) at such other times as the Trustee may
request in writing, within 30 days after receipt by the Company of any such request, a list of
similar form and content to that in subsection (a) hereof as of a date not more than 15 days prior
to the time such list is furnished; provided, however, that if and so long as the Trustee shall be
the Primary Registrar, no such list need be furnished.

     Section 2.07. Transfer and Exchange.

     (a) Subject to compliance with any applicable additional requirements contained below and in
Section 2.13, when a Security is presented to a Registrar with a request to register a transfer
thereof or to exchange such Security for an equal principal amount of Securities of other
authorized denominations, the Registrar shall register the transfer or make the exchange as
requested if its requirements for such transactions are met; provided, however, that every Security
presented or surrendered for registration of transfer or exchange shall be duly endorsed or
accompanied by an assignment form and, if applicable, a transfer certificate each substantially in
the form included in Exhibit A, and completed in a manner satisfactory to the Registrar and duly
executed by the Holder thereof or its attorney duly authorized in writing. To permit registration
of transfers and exchanges, upon surrender of any Security for registration of transfer or exchange
at an office or agency maintained pursuant to Section 2.03, the Company shall execute and the
Trustee shall authenticate Securities of a like aggregate principal amount at the Registrar’s
request. Any exchange or transfer shall be without charge, except that the Company or the
Registrar may require payment of a sum sufficient to cover any transfer tax or similar governmental
charge that may be imposed in relation thereto; provided that this sentence shall not apply to any
exchange pursuant to Section 2.11, 2.13(a), 4.02(d) or 10.06.

     (b) Neither the Company, any Registrar nor the Trustee shall be required to register the
transfer of or exchange any Securities or portions thereof in respect of which a Fundamental Change
Purchase Notice has been delivered and not withdrawn by the Holder thereof (except, in the case of
the purchase of a Security in part, the portion thereof not to be purchased).

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

15

 

     (d) Any Registrar appointed pursuant to Section 2.03 shall provide to the Trustee such
information as the Trustee may reasonably require in connection with the delivery by such Registrar
of Securities upon transfer or exchange of Securities.

     (e) Each Holder of a Security agrees to indemnify the Company and the Trustee against any
liability that may result from the registration of transfer, exchange or assignment of such
Holder’s Security in violation of any provision of this Indenture and/or applicable United States
federal or state securities law.

     (f) 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 Security (including any transfers between or
among Agent Members or other beneficial owners of interests in any Global Security) 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.

     (g) In the case of every Security that bears or is required under this Section 2.07(g) to bear
the legend set forth in this Section 2.07(g) (the “Restricted Securities”), such Security shall be
subject to the restrictions on transfer set forth in this Section 2.07(g) (including the legend set
forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by
written consent of the Company, and the Holder of each such Restricted Security, by such Holder’s
acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this
Section 2.07(g), the term “transfer” encompasses any sale, pledge, transfer or other disposition
whatsoever of any Restricted Security.

     Until the later of the date (the “Resale Restriction Termination Date”) that is (1) the date
that is one year after the Issue Date of the Securities and (2) such later date, if any, as may be
required by applicable laws, any certificate evidencing any Security (and all securities issued in
exchange therefor or substitution thereof) shall bear a legend in substantially the following form
(unless (i) such Security has been transferred (or exchanged for registered securities) pursuant to
a registration statement that was effective at the time of such transfer, (ii) such Security has
been transferred pursuant to the exemption from registration provided by Rule 144 under the
Securities Act or any similar provision then in force under the Securities Act, or (iii) unless
otherwise agreed by the Company in writing, with notice in writing thereof to the Trustee):

THE NOTES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES
SECURITIES ACT OF 1933 (THE “SECURITIES ACT”) AND MAY NOT BE OFFERED, SOLD, PLEDGED
OR OTHERWISE TRANSFERRED EXCEPT (A)(1) TO A PERSON WHO THE SELLER REASONABLY
BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A UNDER
THE SECURITIES ACT PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED
INSTITUTIONAL BUYER IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (2) TO
AN INSTITUTIONAL ACCREDITED INVESTOR IN A TRANSACTION EXEMPT FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT, (3) PURSUANT TO AN EXEMPTION FROM REGISTRATION
UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (4)
PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND (B) IN
ACCORDANCE WITH

16

 

ALL APPLICABLE SECURITIES LAWS OF THE STATES OF THE UNITED STATES.

     No transfer of any Security prior to the Resale Restriction Termination Date shall be
registered by the Registrar unless the applicable box on the completed Form of Assignment and
Transfer (Exhibit A hereto) has been checked and, if such transfer is being made to an
institutional accredited investor pursuant to clause (b) of the restricted securities legend on the
Securities or pursuant to Rule 144 under the Securities Act pursuant to clause (c) of the
restricted securities legend on the Securities, the transferor delivers to the Trustee and the
Company any additional information or documents (including, if requested by the Company, legal
opinions) as are reasonably requested by the Trustee or the Company so as to confirm that such
transfer is being made in compliance with the restrictions set forth in this Section 2.07.

     Any Security (or security issued in exchange or substitution therefor) as to which such
restrictions on transfer shall have expired in accordance with their terms may, upon surrender of
such Security for exchange to any Registrar in accordance with the provisions of this Section
2.07(g), be exchanged for a new Security or Securities, of like tenor and aggregate principal
amount, which shall not bear the restrictive legend required by this Section 2.07(g). The Company
shall notify the Trustee in writing upon the occurrence of the Resale Restriction Termination Date
and, if applicable, promptly after a registration statement with respect to the Securities has been
declared effective under the Securities Act.

     (h) Following the one year anniversary of the Issue Date, any Security that is purchased or
otherwise held by the Company or any affiliate (as defined in Rule 144 under the Securities Act)
thereof may not be sold or otherwise transferred by the Company or such affiliate unless (1) such
Security is sold or otherwise transferred to the Company or an affiliate (as defined in Rule 144
under the Securities Act) of the Company, (2) such transaction is registered under the Securities
Act, or (3) such transaction is made pursuant to an exemption from the registration requirements of
the Securities Act that results in such Security not being a “restricted security” (as defined in
Rule 144 under the Securities Act) in the hands of the acquirer thereof.

     Notwithstanding the foregoing, during the period of one year after the Issue Date, the Company
shall not, and shall not permit any of its “affiliates” (as defined in Rule 144 under the
Securities Act) to, resell any of the Securities that constitute “restricted securities” under Rule
144 under the Securities Act that are held by any of them.

     (i) Notwithstanding any provision of Section 2.07 to the contrary, in the event Rule 144 under
the Securities Act (or any successor rule) is amended to change the one-year holding period
thereunder (or the corresponding period under any successor rule), from and after receipt by the
Trustee of the Officers’ Certificate and Opinion of Counsel provided for in this Section 2.07(i),
(i) each reference in Section 2.07(g) to “one year” shall be deemed for all purposes hereof to be
references to such changed period and (ii) all corresponding references in the Securities
(including the definition of Resale Restriction Termination Date) shall be deemed for all purposes
hereof to be references to such changed period, provided that such changes shall not become
effective if they are otherwise prohibited by, or would otherwise cause a violation of, the
then-applicable U.S. securities laws. The provisions of this Section 2.07(i) shall not be
effective until such time as the Opinion of Counsel and Officers’ Certificate have been received by
the Trustee hereunder. This Section 2.07(i) shall apply to successive amendments to Rule 144 under
the Securities Act (or any successor rule) changing the holding period thereunder.

     Section 2.08. Replacement Securities.

     (a) If (1) any mutilated Security is surrendered to the Trustee, or (2) the Company and the
Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security,
and there is delivered to the Company and the Trustee, such security or indemnity, in each case, as
may be required by them to save each of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a protected purchaser, the Company
shall execute and upon a Company Request the Trustee shall authenticate and deliver, in exchange
for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a
replacement Security of like tenor and principal amount, bearing a number not contemporaneously
outstanding and each Guarantor shall execute a replacement Guarantee.

     (b) If any such mutilated, destroyed, lost or stolen Security has become or is about to become
due and payable, or is about to be purchased by the Company pursuant to Article 3, or cash
converted pursuant to Article 4, the Company in its discretion may, instead of issuing a new
Security, pay, purchase or cash convert such Security, as the case may be.

     (c) Upon the issuance of any new Securities under this Section 2.08, the Company may require
the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto and any other expenses (including the fees and expenses of counsel and the
Trustee) in connection therewith.

     (d) Every new Security and Guarantee issued pursuant to this Section 2.08 in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual
obligation of the Company and each Guarantor, whether or not the mutilated, destroyed, lost or stolen
Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this
Indenture equally and proportionately with any and all other Securities duly issued hereunder.

     (e) The provisions of this Section 2.08 are (to the extent lawful) exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

     Section 2.09. Outstanding Securities.

     (a) Securities outstanding (“Outstanding”) at any time are all Securities authenticated by the
Trustee, except for those canceled by it, those purchased pursuant to Article 3, those cash
converted pursuant to Article 4, those delivered to the Trustee for cancellation or surrendered for
transfer or exchange and those described in this Section 2.09 as not Outstanding.

     (b) If a Security is replaced pursuant to Section 2.08, such replaced Security ceases to be
Outstanding unless the Company receives proof satisfactory to it that the replaced Security is held
by a protected purchaser.

     (c) If a Paying Agent holds in respect of the Outstanding Securities on a Fundamental Change
Purchase Date, the Final Maturity Date or any date of any cash conversion money sufficient to pay
the principal of or Conversion Reference Value with respect to and accrued interest on Securities
(or portions thereof) payable on that date, then on and after such Fundamental Change Purchase
Date, Final Maturity Date or date of cash conversion, as the case may be, such Securities (or
portions thereof, as the case may be) shall cease to be Outstanding and interest on them shall
cease to accrue.

18

 

     (d) Subject to the restrictions contained in Section 2.10, a Security does not cease to be
Outstanding because the Company or an Affiliate of the Company holds the Security.

     Section 2.10. Treasury Securities.

     In determining whether the Holders of the required principal amount of Securities have
concurred in any request, demand, authorization, notice, direction, waiver or consent, Securities
owned by the Company or any other obligor on the Securities or by any Affiliate of the Company or
of such other obligor shall be disregarded, except that, for purposes of determining whether the
Trustee shall be protected in relying on any such request, demand, authorization, notice,
direction, waiver or consent, only Securities which a Trust Officer of the Trustee actually knows
are so owned shall be so disregarded.

     Section 2.11. Temporary Securities.

     Until Definitive Securities are ready for delivery, the Company may prepare and execute, and,
upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary Securities.
Temporary Securities shall be substantially in the form of Definitive Securities but may have
variations that the Company with the consent of the Trustee considers appropriate for temporary
Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate and deliver Definitive Securities in exchange for temporary Securities representing an
equal principal amount of Securities. The temporary Securities will be exchanged for Definitive
Securities in accordance with Sections 2.07 and 2.13 hereof. Until so exchanged, temporary
Securities shall have the same rights under this Indenture as the Definitive Securities.

     Section 2.12. Cancellation.

     The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar
and the Paying Agent shall forward to the Trustee any Securities surrendered to them for transfer,
exchange, purchase, payment or cash conversion. The Trustee and no one else shall cancel, in
accordance with its standard procedures, all Securities surrendered for transfer, exchange,
purchase, payment, cash conversion or cancellation and shall dispose of the canceled Securities in
accordance with its customary procedures or deliver the canceled Securities to the Company upon
request. All Securities which are purchased or otherwise acquired by the Company or any of its
Subsidiaries prior to the Final Maturity Date pursuant to Article 3 shall be delivered to the
Trustee for cancellation, and the Company may not hold or resell such Securities or issue any new
Securities to replace any such Securities or any Securities that any Holder has cash converted
pursuant to Article 4. The Trustee shall maintain a record of all canceled Securities. The
Trustee shall provide the Company a list of all Securities that have been canceled from time to
time as requested by the Company in writing.

     Section 2.13. Legend; Additional Transfer and Exchange Requirements.

     (a) A Global Security may not be transferred, in whole or in part, to any Person other than
the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person
may be registered; provided that the foregoing shall not prohibit any transfer of a Security that
is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a
Security to any Person shall be effective under this Indenture or the Securities unless and until
such Security has been registered in the name of such Person. Notwithstanding any other provisions
of this Indenture or the Securities, transfers of a Global Security, in whole or in part, shall be
made only in accordance with this Section 2.13.

19

 

     (b) The provisions below shall apply only to Global Securities:

     (1) Each Global Security 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 Security shall constitute a single
Security for purposes of this Indenture.

     (2) Notwithstanding any other provisions of this Indenture or the Securities, a Global
Security shall not be exchanged in whole or in part for a Security registered, and no
transfer of a Global Security in whole or in part shall be registered in the name of any
Person other than the Depositary or one or more nominees thereof; provided that a Global
Security may be exchanged for Securities registered in the names of any person designated by
the Depositary in the event that (A) the Depositary has notified the Company that it is
unwilling or unable to continue as Depositary for such Global Security or such Depositary
has ceased to be a “clearing agency” registered under the Exchange Act, and in either case a
successor Depositary is not appointed by the Company within 90 days after receiving such
notice or becoming aware that the Depositary has ceased to be a “clearing agency,” (B) an
Event of Default has occurred and is continuing with respect to the Securities or (C) the
Company executes and delivers to the Trustee and the Primary Registrar an Officer’s
Certificate stating that such Global Security shall be so exchangeable. Any Global Security
exchanged pursuant to the preceding sentence shall be so exchanged as directed by the
Depositary. Any Security issued in exchange for a Global Security or any portion thereof
shall be a Global Security; provided, however, that any such Security so issued that is
registered in the name of a Person other than the Depositary or a nominee thereof shall not
be a Global Security.

     (3) Securities issued in exchange for a Global Security or any portion thereof that are
not issued as a Global Security shall be issued in definitive, fully registered form,
without interest coupons, shall have a principal amount equal to that of such Global
Security or portion thereof to be so exchanged, shall be registered in such names and be in
such authorized denominations as the Depositary shall designate and shall bear the
applicable legends provided for herein. Any Global Security to be exchanged in whole shall
be surrendered by the Depositary to the Trustee or the Registrar. With regard to any Global
Security to be exchanged in part, either such Global Security shall be so surrendered for
exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with
respect to such Global Security, the principal amount thereof shall be reduced, by an amount
equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made
on the records of the Trustee and upon such Global Security. Upon any such surrender or
adjustment, the Trustee shall authenticate and deliver the Security issuable on such
exchange to or upon the order of the Depositary or an authorized representative thereof.

     (4) Subject to clause (6) of this Section 2.13(b), the registered Holder may grant
proxies and otherwise authorize any Person, including Agent Members and Persons that may
hold interests through Agent Members, to take any action which a Holder is entitled to take
under this Indenture or the Securities.

     (5) In the event of the occurrence of any of the events specified in clause (2) of this
Section 2.13(b), the Company will promptly make available to the Trustee a reasonable supply
of Certificated Securities in definitive, fully registered form, without interest coupons.

     (6) Neither 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 Security registered in
the name of the Depositary or any nominee thereof, or under any such Global Security, and
the

20

 

Depositary or such nominee, as the case may be, may be treated by the Company, the
Trustee and any agent of the Company, the Trustee and any agent of the Company or the
Trustee as the absolute owner and Holder of such Global Security for all purposes
whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the
Company or the Trustee from giving effect to any written certification, proxy or other
authorization furnished by the 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 Security.

     (7) At such time as all interests in a Global Security have been converted, canceled or
exchanged for Securities in certificated form, such Global Security shall, upon receipt
thereof, be canceled by the Trustee in accordance with standing procedures and instructions
existing between the Depositary and the Securities Custodian, subject to Section 2.12 of
this Indenture. At any time prior to such cancellation, if any interest in a Global
Security is converted, canceled or exchanged for Securities in certificated form, the
principal amount of such Global Security shall, in accordance with the standing procedures
and instructions existing between the Depositary and the Securities Custodian, be
appropriately reduced, and an endorsement shall be made on such Global Security, by the
Trustee or the Securities Custodian, at the direction of the Trustee, to reflect such
reduction.

     Section 2.14. CUSIP Numbers.

     The Company in issuing the Securities may use one or more “CUSIP,” “ISIN” or other similar
numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP,” “ISIN” or other
similar numbers in a Fundamental Change Purchase Notice as a convenience to Holders; provided that
any such notice may state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any Fundamental Change Purchase Notice and
that reliance may be placed only on the other identification numbers printed on the Securities, and
any such purchase shall not be affected by any defect in or omission of such numbers. The Company
will notify the Trustee in writing of any change in the “CUSIP,” “ISIN” or other similar numbers.

     Section 2.15. Calculations.

     Except as otherwise specifically stated herein or in the Securities, all calculations to be
made in respect of the Securities shall be the obligation of the Company. All calculations made by
the Company or its agent as contemplated pursuant to the terms hereof and of the Securities shall
be made in good faith and be final and binding on the Holders absent manifest error. The Company
shall provide a schedule of calculations to the Trustee upon the Trustee’s request, and the Trustee
shall be entitled to conclusively rely upon the accuracy of the calculations by the Company without
independent verification. The Trustee shall forward calculations made by the Company to any Holder
of Securities upon request.

     Section 2.16. Payment of Interest; Interest Rights Preserved.

     Interest on any Security which is payable, and is punctually paid or duly provided for, on the
Stated Maturity of such interest shall be paid to the Person in whose name the Security is
registered at the close of business on the Regular Record Date for such interest payment.

     Any interest on any Security which is payable, but is not punctually paid or duly provided
for, on the Stated Maturity of such interest, and interest on such defaulted interest at the then
applicable interest

21

 

rate borne by the Securities, to the extent lawful (such defaulted interest and
interest thereon herein collectively called “Defaulted Interest”), shall forthwith cease to be
payable to the Holder on the Regular Record Date; and such Defaulted Interest may be paid by the
Company, at its election in each case, as provided in subsection (a) or (b) below:

     (a) The Company may elect to make payment of any Defaulted Interest to the Persons in
whose names the Securities are registered at the close of business on a Special Record Date
for the payment of such Defaulted Interest, which shall be fixed in the following manner.
The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed
to be paid on each Security and the date (not less than 20 days after such notice) of the
proposed payment (the “Special Payment Date”), and on the date of payment the Company shall
deposit with the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the
Trustee for such deposit prior to the Special Payment Date, such money when deposited to be
held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this
subsection provided. There upon the Trustee shall fix a Special Record Date for the payment
of such Defaulted Interest which shall be not more than 15 days and not less than 10 days
prior to the date of the Special Payment Date and not less than 10 days after the receipt by
the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the
Company in writing of such Special Record Date. Unless the Company issues a press release
to the same effect, in the name and at the expense of the Company, the Trustee 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 Security Register, not less than 10 days prior to such Special Record Date or
notify in such other manner as the Trustee determines, including in accordance with any
Applicable Procedures. Notice of the proposed payment of such Defaulted Interest and the
Special Record Date and Special Payment Date therefor having been so mailed or otherwise
conveyed, such Defaulted Interest shall be paid to the Persons in whose names the Securities
are registered on such Special Record Date and shall no longer be payable pursuant to the
following paragraph (b).

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

     Subject to the foregoing provisions of this Section 2.16, each Security delivered under this
Indenture upon registration of transfer of or in exchange for or in lieu of any other Security
shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

     Section 2.17. Computation of Interest.

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

     Section 2.18. Deemed Removal of Restricted Securities Legend; Unrestricted CUSIP.

     At any time on or after the Resale Restriction Termination Date, the Company shall have the
option, exercisable in its sole discretion, to remove the restricted securities legend on any
Security provided

22

 

for by Section 2.07(g) by delivering a certificate to the Trustee substantially
in the form of Exhibit D hereto. Upon receipt of such certificate by the Trustee, the restricted
securities legend on any such Securities shall be deemed removed and an unrestricted CUSIP number
shall be deemed substituted for the restricted CUSIP number thereon.

ARTICLE 3

PURCHASE

     Section 3.01. Purchase of Securities by the Company for Cash
at Option of the Holder upon a Fundamental Change.

     (a) If a Fundamental Change occurs prior to the Final Maturity Date, each Holder of a Security
shall have the right, at the option of the Holder, to require the Company to purchase for cash in
whole or in part (in principal amounts of $1,000 and integral multiples thereof) the Securities of
such Holder at the Fundamental Change Purchase Price on the date specified by the Company that is
not less than 30 days and not more than 45 days after the date of the Issuer Fundamental Change
Notice (the “Fundamental Change Purchase Date”).

     (b) Not later than 10 Business Days after the Fundamental Change Effective Date, the Company
shall mail a written notice of the Fundamental Change and of the resulting purchase right to the
Trustee, Paying Agent and to each Holder of record of Securities (an “Issuer Fundamental Change
Notice”). The Issuer Fundamental Change Notice shall include the form of a Fundamental Change
Purchase Notice (defined below) to be completed by the Holder and shall state:

     (1) the events causing such Fundamental Change;

     (2) the date (or expected date) of such Fundamental Change;

     (3) the last date by which the Fundamental Change Purchase Notice must be delivered to
elect the purchase option pursuant to this Section 3.01;

     (4) the Fundamental Change Purchase Date;

     (5) the Fundamental Change Purchase Price;

     (6) the Holder’s right to require the Company to purchase the Securities;

     (7) the name and address of the Paying Agent;

     (8) the then effective Conversion Reference Rate and any adjustments to the Conversion
Reference Rate resulting from such Fundamental Change;

     (9) the procedures that the Holder must follow to exercise rights under Article 4 of
this Indenture and that the Securities as to which a Fundamental Change Purchase Notice has
been given may be cash converted pursuant to Article 4 of this Indenture only to the extent
that the Fundamental Change Purchase Notice has been withdrawn in accordance with the terms
of this Indenture;

23

 

     (10) the procedures that the Holder must follow to exercise rights under this Section
3.01;

     (11) the procedures for withdrawing a Fundamental Change Purchase Notice;

     (12) that, unless the Company fails to pay such Fundamental Change Purchase Price,
Securities covered by any Fundamental Change Purchase Notice will cease to be outstanding
and interest will cease to accrue on and after the Fundamental Change Purchase Date; and

     (13) the CUSIP, ISIN or other similar number of the Securities.

     At the Company’s written request, the Trustee shall give such Issuer Fundamental Change Notice
in the Company’s name and at the Company’s expense; provided that, in all cases, the text of such
Issuer Fundamental Change Notice shall be prepared by the Company. In connection with the delivery
of the Issuer Fundamental Change Notice to the Holders, the Company shall publish a notice
containing substantially the same information that is required in the Issuer Fundamental Change
Notice in a newspaper of general circulation in the City of New York or publish information on a
website of the Company or through such other public medium the Company may use at that time. If
any of the Securities is in the form of a Global Security, then the Company shall modify such
notice to the extent necessary to accord with the Applicable Procedures relating to the purchase of
Global Securities.

     (c) A Holder may exercise its rights specified in Section 3.01(a) upon delivery of a written
notice (which shall be in substantially the form set forth in the form of Security attached as
Exhibit A under the heading “Fundamental Change Purchase Notice” and which may be delivered by
letter, overnight courier, hand delivery, facsimile transmission or in any other written form and,
in the case of Global Securities, may be delivered electronically or by other means in accordance
with the Depositary’s Applicable Procedures) of the exercise of such rights (a “Fundamental Change
Purchase Notice”) to the Paying Agent at any time prior to the close of business on the Business
Day immediately preceding the Fundamental Change Purchase Date, subject to extension to comply with
applicable law.

     (1) The Fundamental Change Purchase Notice shall state: (A) if the Securities are in
certificated form, the certificate numbers of the Securities which the Holder will deliver
to be purchased (or, if the Security is held in global form, any other items required to
comply with the Applicable Procedures), (B) the portion of the principal amount of the
Securities which the Holder will deliver to be purchased, which portion must be a principal
amount of $1,000 or any integral multiple thereof and (C) that such Security shall be
purchased as of the Fundamental Change Purchase Date pursuant to the terms and conditions
specified in the Securities and in this Indenture.

     (2) The delivery of a Security for which a Fundamental Change Purchase Notice has been
timely delivered to any Paying Agent and not validly withdrawn prior to, on or after the
Fundamental Change Purchase Date (together with all necessary endorsements) at the office of
such Paying Agent shall be a condition to the receipt by the Holder of the Fundamental
Change Purchase Price therefor.

     (3) The Company shall only be obliged to purchase, pursuant to this Section 3.01, a
portion of a Security if the principal amount of such portion is $1,000 or an integral
multiple thereof. Provisions of this Indenture that apply to the purchase of all of a
Security also apply to the purchase of such portion of such Security.

24

 

     (4) Notwithstanding anything herein to the contrary, any Holder delivering to a Paying
Agent the Fundamental Change Purchase Notice contemplated by this Section 3.01(c) shall have
the right to withdraw such Fundamental Change Purchase Notice in whole or in a portion
thereof that is a principal amount of $1,000 or in an integral multiple thereof at any time
prior to the close of business on the Business Day prior to the Fundamental Change Purchase
Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with
Section 3.02(b).

     (5) A Paying Agent shall promptly notify the Company of the receipt by it of any
Fundamental Change Purchase Notice or written withdrawal thereof.

     (6) Anything herein to the contrary notwithstanding, in the case of Global Securities,
any Fundamental Change Purchase Notice shall be delivered or withdrawn and such Securities
shall be surrendered or delivered for purchase in accordance with the Applicable Procedures
as in effect from time to time.

     Section 3.02. Effect of Fundamental Change Purchase Notice.

     (a) Upon receipt by any Paying Agent of a properly completed Fundamental Change Purchase
Notice from a Holder, the Holder of the Security in respect of which such Fundamental Change
Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn as
specified in Section 3.02(b)) thereafter be entitled to receive the Fundamental Change Purchase
Price with respect to such Security. Such Fundamental Change Purchase Price shall be paid to such
Holder promptly following the later of (1) the Fundamental Change Purchase Date (provided that the
conditions in Section 3.01 have been satisfied) and (2) the time of delivery of such Security to a
Paying Agent by the Holder thereof in the manner required by Section 3.01(c). Securities in
respect of which a Fundamental Change Purchase Notice has been given by the Holder thereof may not
be cash converted in accordance with the provisions of Article 4 on or after the date of the
delivery of such Fundamental Change Purchase Notice unless such Fundamental Change Purchase Notice
has first been validly withdrawn in accordance with Section 3.02(b) with respect to the Securities
to be cash converted.

     (b) A Fundamental Change Purchase Notice may be withdrawn by means of a written notice (which
may be delivered by mail, overnight courier, hand delivery, facsimile transmission or in any other
written form and, in the case of Global Securities, may be delivered electronically or by other
means in accordance with the Applicable Procedures) of withdrawal delivered by the Holder to a
Paying Agent at any time prior to the close of business on the Business Day immediately prior to
the Fundamental Change Purchase Date, specifying (1) the principal amount of the Security or
portion thereof (which must be a principal amount of $1,000 or an integral multiple of $1,000 in
excess thereof) with respect to which such notice of withdrawal is being submitted, (2) if the
Securities are in certificated form, the certificate numbers of the Security being withdrawn in
whole or in part and (3) the portion of the principal amount of the Security that will remain
subject to the Fundamental Change Purchase Notice, which portion must be a principal amount of
$1,000 or an integral multiple thereof. Anything herein to the contrary notwithstanding, in the
case of Global Securities, any Fundamental Change Purchase Notice shall be withdrawn in accordance
with the Applicable Procedures as in effect from time to time.

     Section 3.03. Deposit of Fundamental Change Purchase Price.

     (a) On or before 10:00 a.m. New York City time on the applicable Fundamental Change Purchase
Date, the Company shall deposit with the Trustee or with a Paying Agent (or if the Company or an
Affiliate of the Company is acting as the Paying Agent, shall segregate and hold in trust as
provided in Section 2.04) an amount of money (in immediately available funds if deposited on or
after such Funda-

25

 

mental Change Purchase Date), sufficient to pay the aggregate Fundamental Change
Purchase Price of all the Securities or portions thereof that are to be purchased as of the
Fundamental Change Purchase Date.

     (b) If a Paying Agent or the Trustee holds on the Fundamental Change Purchase Date in
accordance with the terms hereof an amount of money sufficient to pay the Fundamental Change
Purchase Price of any Security (or portion thereof) for which a Fundamental Change Purchase Notice
has been tendered and not withdrawn in accordance with this Indenture then, immediately following
the applicable Fundamental Change Purchase Date, whether or not the Security is delivered to the
Paying Agent for purchase, such Security shall cease to be outstanding, interest, shall cease to
accrue, and the rights of the Holder in respect of the Security shall terminate (other than the
right to receive the Fundamental Change Purchase Price upon delivery of the Security as aforesaid).

     (c) The Paying Agent will promptly return to the respective Holders thereof any Securities
with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with
this Indenture.

     (d) If a Fundamental Change Purchase Date falls after a Regular Record Date and on or before
the related Interest Payment Date, then interest on the Securities payable on such Interest Payment
Date, together with the interest due on the Securities to, but excluding, such Fundamental Change
Purchase Date, will be payable to the Holders in whose names the Securities are registered at the
close of business on such Regular Record Date.

     Section 3.04. Repayment to the Company.

     To the extent that the aggregate amount of cash deposited by the Company pursuant to Section
3.03 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions thereof
that the Company is obligated to purchase, then promptly after the Fundamental Change Purchase Date
the Trustee or a Paying Agent, as the case may be, shall return any such excess cash to the
Company, or if such money is then held by the Company in trust, it shall be discharged from the
trust.

     Section 3.05. Securities Purchased in Part.

     Any Security that is to be purchased only in part shall be surrendered at the office of a
Paying Agent, and promptly after the Fundamental Change Purchase Date, as the case may be, the
Company shall execute and the Trustee shall authenticate and deliver to the Holder of such
Security, without service charge, a new Security or Securities, of such authorized denomination or
denominations as may be requested by such Holder (which must be equal to $1,000 principal amount or
any integral multiple thereof), in aggregate principal amount equal to, and in exchange for, the
portion of the principal amount of the Security so surrendered that is not purchased.

     Section 3.06. Compliance with Securities Laws upon Purchase of Securities.

     In connection with any offer to purchase Securities under Section 3.01, the Company shall (a)
comply with the provisions of the tender offer rules under the Exchange Act which may then be
applicable, (b) file the related Schedule TO (or any successor or similar schedule, form or report)
if required under the Exchange Act, and (c) otherwise comply with all federal and state securities
laws in connection with such offer to purchase or purchase of Securities, all so as to permit the
rights of the Holders and obligations of the Company under Sections 3.01 through 3.04 to be
exercised in the time and in the manner specified therein. To the extent that compliance with any
such laws, rules and regulations would result in

26

 

a conflict with any of the terms hereof, this
Indenture is hereby modified to the extent required for the Company to comply with such laws, rules
and regulations.

     Section 3.07. Purchase of Securities in Open Market.

     The Company may purchase Securities in the open market or by tender at any price or pursuant
to private agreements. The Company shall surrender any Security purchased by the Company pursuant
to this Article 3 to the Trustee for cancellation. Any Securities surrendered to the Trustee for
cancellation may not be reissued or resold by the Company and will be canceled promptly in
accordance with Section 2.12.

ARTICLE 4

CASH CONVERSION

     Section 4.01. Cash Conversion Privilege and Conversion Reference Rate.

     (a) Any Security or portion thereof that is an integral multiple of $1,000 principal amount
may be cash converted by the Holder thereof in accordance with the provisions of this Article 4.
Upon cash conversion, Holders shall be entitled to receive the amount of cash determined in the
manner provided in Section 4.12. Securities may be cash converted prior to the close of business
on the third Business Day immediately preceding the Final Maturity Date at the Conversion Reference
Rate in effect at the time of such conversion only under the following circumstances:

     (1) on any Business Day in any calendar quarter commencing at any time after December
31, 2008, and only during such calendar quarter, if, as of the last day of the immediately
preceding calendar quarter, the Closing Price of the Common Stock for at least 20 Trading
Days in the period of 30 consecutive Trading Days ending on the last Trading Day of such
preceding calendar quarter was more than 130% of the applicable Conversion Reference Price
on the last day of such preceding calendar quarter;

     (2) on any Business Day during the five Business Day period after any five consecutive
Trading Day period in which the Trading Price per $1,000 principal amount of Securities, as
determined by the Trustee following a request by a Holder in accordance with the procedures
described in Section 4.01(b), for each Trading Day of that period was less than 98% of the
product of the Closing Price of the Common Stock on such day and the then applicable
Conversion Reference Rate per $1,000 principal amount of Securities.

     (3) if the Company distributes to all holders of Common Stock any rights entitling them
to purchase, for a period expiring within 45 days of such distribution, Common Stock, or
securities convertible into Common Stock, at less than, or having a conversion price per
share less than, the Closing Price of the Common Stock on the Trading Day immediately
preceding the declaration date for such distribution;

     (4) if the Company distributes to all holders of Common Stock assets, cash, debt
securities or rights to purchase the Company’s securities, which distribution has a per
share value as determined by the Board of Directors exceeding 15% of the Closing Price per
share of the Common Stock on the Trading Day immediately preceding the declaration date for
such distribution;

27

 

     (5) if the Company is a party to any transaction or event (including any consolidation,
merger or binding share exchange, other than changes resulting from a subdivision or
combination) that is not otherwise a Fundamental Change pursuant to which all or
substantially all shares of the Common Stock would be converted into cash, securities or
other property (provided that the Securities shall not become cash convertible by reason of
a merger, consolidation or other transaction effected by the Company with one of its direct
or indirect Subsidiaries for the purpose of changing the Company’s state of incorporation or
organization to any other state within the United States or the District of Columbia);

     (6) if a Fundamental Change occurs; or

     (7) at any time during the period beginning on June 15, 2015 and ending at the close of
business on the third Business Day immediately preceding the Final Maturity Date.

     (b) The Trustee shall have no obligation to determine the Trading Price of the Securities and
whether the Securities are cash convertible pursuant to clause (2) of Section 4.01(a) unless the
Company has requested such determination and the Company shall have no obligation to make such
request unless a Holder of the Securities provides the Company with reasonable evidence that the
Trading Price per $1,000 principal amount of Securities would be less than 98% of the product of
the Closing Price of the Common Stock and the then applicable Conversion Reference Rate per $1,000
principal amount of Securities. At such time, the Company shall instruct the Trustee to determine
the Trading Price of the Securities beginning on the next Trading Day and on each successive
Trading Day until the Trading Price per $1,000 principal amount of the Securities is greater than
98% of the product of the Closing Price of the Common Stock and the then applicable Conversion
Reference Rate per $1,000 principal amount of the Securities.

     (c) In the case of a distribution contemplated by clause (3) or (4) of Section 4.01(a), the
Company shall notify Holders and the Trustee at least 35 days prior to the ex-dividend date for
such distribution (the “Distribution Notice”). Once the Company has given the Distribution Notice,
Holders may surrender their Securities for cash conversion at any time until the earlier of the
close of business on the Business Day prior to the ex-dividend date or the Company’s announcement
that such distribution will not take place. In the event of a distribution contemplated by clause
(3) or (4) of Section 4.01(a), Holders may not cash convert the Securities if the Holders will
otherwise participate in such distribution on an “as converted” basis (i.e., as though such
Holder had exchanged each $1,000 principal amount of its Securities immediately prior to the record
date for such distribution for a number of shares of Common Stock equal to the then applicable
Conversion Reference Rate). “ex-dividend date” is the first date upon which a sale of the Common
Stock does not automatically transfer the right to receive the relevant distribution from the
seller of the Common Stock to its buyer. The Company will provide written notice to the Paying
Agent as soon as reasonably practicable of any anticipated or actual event or transaction that will
cause or causes the Securities to become cash convertible pursuant to clauses (3) or (4) of Section
4.01(a).

     (d) In the case of a transaction contemplated by clause (5) of Section 4.01(a), the Company
will notify Holders and the Trustee as promptly as practicable following the date the Company
publicly announces such transaction (but in no event less than 15 days prior to the anticipated
effective date of such transaction). Holders may surrender Securities for cash conversion at any
time from and after the date which is 15 days prior to the anticipated effective date of such
transaction until the earlier of the date which is 15 days after the actual effective date of such
transaction or the date of the Company’s announcement that such transaction will not take place.

28

 

     (e) In the case of a Fundamental Change, the Company shall provide notice thereof (a
“Fundamental Change Conversion Notice”) to the Holders of Securities and the Trustee not more than
10 Business Days after the date that is the Fundamental Change Effective Date. Holders may
surrender Securities for cash conversion at any time after receipt of such notice and until the
close of business on the Trading Day prior to the Fundamental Change Purchase Date.

     (f) The cash conversion rights pursuant to this Article 4 shall commence on the Issue Date and
expire at the close of business on the third Business Day immediately preceding the Final Maturity
Date, but shall be exercisable only during the time periods specified with respect to each
circumstance pursuant to which the Securities become cash convertible, subject, in the case of cash
conversion of any Global Security, to any Applicable Procedures.

     (g) Securities in respect of which a Fundamental Change Purchase Notice has been delivered may
not be surrendered for cash conversion pursuant to this Article 4 prior to a valid withdrawal of
such Fundamental Change Notice, in accordance with the provisions of Article 3.

     (h) Provisions of this Indenture that apply to cash conversion of all of a Security also apply
to cash conversion of a portion of a Security.

     (i) The Conversion Reference Rate shall be adjusted in certain instances as provided in
Section 4.01(j) and Section 4.06.

     (j) If a Fundamental Change occurs prior to the Final Maturity Date as a result of a
transaction described in clauses (1), (2) or (4) of the definition of the term “Change of Control”
and a Holder elects to cash convert its Securities in connection with such transaction, the Company
shall pay a “Make Whole Premium” if and as required by the below by increasing the applicable
Conversion Reference Rate for the Securities surrendered for cash conversion by a number of
additional shares of Common Stock as provided in this Section 4.01(j) (the “Additional Shares”). A
cash conversion of Securities shall be deemed for these purposes to be “in connection with” such a
transaction if the notice of cash conversion is received by the Paying Agent from and including the
Fundamental Change Effective Date and prior to the close of business on the Business Day prior to
the Fundamental Change Purchase Date.

     The number of Additional Shares per $1,000 principal amount of Securities constituting the
Make Whole Premium, if any, shall be determined by reference to the table below and shall be based
on the date on which the Fundamental Change Effective Date occurs and the price (the “Stock Price”)
paid, or deemed to be paid, per share of Common Stock in such transaction. If holders of Common
Stock receive only cash in the Fundamental Change transaction, the Stock Price shall be the cash
amount paid per share of Common Stock. Otherwise, the Stock Price shall be the average of the
Closing Prices of the Common Stock for each of the ten consecutive Trading Days prior to but
excluding the Fundamental Change Effective Date.

     The following table sets forth the Additional Share amounts, if any, by which the applicable
Conversion Reference Rate shall be increased for each Stock Price and Fundamental Change Effective
Date.

     If the actual Stock Price or Fundamental Change Effective Date is not set forth in the table
above, then:

     (i) if the actual Stock Price on the Fundamental Change Effective Date is between two
Stock Price amounts in the table or the actual Fundamental Change Effective Date is between
two Fundamental Change Effective Dates in the table, the Additional Share amounts will be
determined by a straightline interpolation between the Additional Share amounts set forth
for the higher and lower Stock Prices and the two Fundamental Change Effective Dates on the
table based on a 365-day year;

     (ii) if the actual Stock Price on the Fundamental Change Effective Date exceeds $70.00
per share of Common Stock, subject to adjustment as set forth herein, no adjustment to the
Conversion Reference Rate shall be made; and

     (iii) if the actual Stock Price on the Fundamental Change Effective Date is less than
$11.10 per share of Common Stock, subject to adjustment as set forth herein, no adjustment
to the Conversion Reference Rate shall be made.

     The Stock Prices set forth in the first column of the table above and in clauses (ii) and
(iii) above will be adjusted as of any date on which the Conversion Reference Rate of the
Securities is adjusted pursuant to Section 4.06 hereof. The adjusted Stock Prices will equal the
Stock Prices applicable immediately prior to such adjustment multiplied by a fraction, the
numerator of which is the Conversion Reference Rate immediately prior to the adjustment giving rise
to the Stock Price adjustment and the denominator of which is the Conversion Reference Rate as so
adjusted. The number of Additional Share amounts set forth in the table above will be adjusted in
the same manner as the Conversion Reference Rate as set forth in Section 4.06 hereof.

     Notwithstanding the foregoing, in no event shall the Conversion Reference Rate exceed 90.0900
shares of Common Stock per $1,000 principal amount of Securities, subject to adjustment in the same
manner as the Conversion Reference Rate as set forth in subsections (a) through (e) of Section 4.06
hereof.

     Section 4.02. Conversion Procedure.

     (a) To cash convert a Security, a Holder must (1) complete and manually sign the cash
conversion notice on the back of the Security (which shall be substantially in the form set forth
in the form of Security attached as Exhibit A under the heading “Cash Conversion Notice”) and
deliver such notice to the Paying Agent, (2) surrender the Security to the Paying Agent, (3)
furnish appropriate endorsements and transfer documents if required by the Paying Agent, (4) pay an
amount equal to the interest payable on the next Interest Payment Date if and as required by
Section 4.02(c) and (5) pay all transfer or similar taxes required in connection therewith. The
date on which the Holder of a Security satisfies all of the foregoing requirements is the “Cash
Conversion Trigger Date” with respect to such Security. Upon the cash conversion of a Security, the
Company shall deliver cash in the amounts determined in accordance with Section 4.12 which shall be
owing upon such cash conversion as promptly as practicable after the applicable Conversion
Reference Period but in any event not later than the third Business Day following

30

 

the last Trading
Day of such Conversion Reference Period. Anything herein to the contrary notwithstanding, in the
case of Global Securities, such Securities shall be surrendered in accordance with the Applicable
Procedures of the Depositary as in effect from time to time.

     (b) A Holder shall not be entitled to convert Securities into shares of Common Stock or any
other security, nor shall a Holder be entitled to any rights as a holder of Common Stock.

     (c) Holders of Securities surrendered for cash conversion (in whole or in part) during the
period from the close of business on any Regular Record Date to the opening of business on the next
succeeding Interest Payment Date will receive the semiannual interest payable on such Securities on
the corresponding Interest Payment Date notwithstanding the cash conversion of such Securities, and
such interest shall be payable on the corresponding Interest Payment Date to the Holder of the
Security as of the close of business on the Regular Record Date. Upon surrender of any such
Securities for cash conversion after the close of business on such Regular Record Date, such
Securities shall also be accompanied by payment by the Holders of such Securities in funds to the
Paying Agent acceptable to the Company of an amount equal to the interest payable on such
corresponding Interest Payment Date; provided that no such payment need be made: (1) in connection with a cash conversion following the Regular Record
Date preceding the Final Maturity Date; (2) if the Company has specified a Fundamental Change
Purchase Date that is after a Regular Record Date and on or prior to the first Scheduled Trading
Day following the corresponding Interest Payment Date; or (3) to the extent of any overdue
interest, if any overdue interest exists at the time of cash conversion with respect to such
Security. Except as otherwise provided in this Section 4.02(c), no payment or adjustment will be
made for accrued and unpaid interest on a cash converted Security. Accrued and unpaid interest
shall be deemed paid in full, rather than canceled, extinguished or forfeited, upon payment of the
cash amount due upon conversion pursuant to Section 4.02(a). The Company shall not be required to
cash convert any Securities which are surrendered for cash conversion without payment of interest
as required by this Section 4.02(c).

     (d) In the case of any Security which is cash converted in part only, upon such cash
conversion the Company shall execute and the Trustee shall authenticate and deliver to the Holder
thereof, without service charge, a new Security or Securities of authorized denominations in an
aggregate principal amount equal to, and in exchange for, the unconverted portion of the principal
amount of such Security.

     Section 4.03. [Reserved].

     Section 4.04. [Reserved].

     Section 4.05. [Reserved].

     Section 4.06. Adjustment of Conversion Reference Rate.

     The Conversion Reference Rate shall be adjusted from time to time by the Company as follows:

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

	 	 	 	 	 	 
	 	CR1 =  
	 	CR0 x OS1
 

OS0
	 	   

     where

31

 

	 	CR0 =	 	the Conversion Reference Rate in effect immediately prior to the adjustment relating to such event
	 
	 	CR1 =	 	the new Conversion Reference Rate in effect taking such event into account
	 
	 	OS0 =	 	the number of shares of Common Stock outstanding immediately prior to such event
	 
	 	OS1 =	 	the number of shares of Common Stock outstanding immediately after such event.

Any adjustment made pursuant to this Section 4.06(a) shall become effective on the date that
is immediately after (x) the date fixed for the determination of stockholders 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 Section 4.06(a) is declared but not so paid or made, the new Conversion
Reference Rate shall be readjusted to the Conversion Reference Rate that would then be in
effect if such dividend or distribution had not been declared.

     (b) If the Company issues to all holders of Common Stock 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 Stock, or if the Company issues to all
holders of Common Stock securities convertible into Common Stock for a period of not more
than 45 days after the date of issuance thereof, in either case at an exercise price per
share of Common Stock or a conversion reference price per share of Common Stock less than
the Closing Price of the Common Stock on the Business Day immediately preceding the time of
announcement of such issuance, the Conversion Reference Rate will be adjusted based on the
following formula:

	 	 	 	 	 	 
	 	CR1 =  
	 	CR0 x (OS0 + X)
 

(OS0 + Y)
	 	   

     where

	 	CR0 =	 	the Conversion Reference Rate in effect immediately prior to the adjustment relating to such event
	 
	 	CR1 =	 	the new Conversion Reference Rate taking such event into account
	 
	 	OS0 =	 	the number of shares of Common Stock outstanding immediately prior to such event
	 
	 	X =	 	the total number of shares of Common Stock issuable pursuant to such rights,
warrants, options, other securities or convertible securities
	 
	 	Y =	 	the number of shares of Common Stock 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 Prices of the Common Stock
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 Section 4.06(b), in determining whether any rights, warrants, options,
other securities or convertible securities entitle the holders to subscribe for or purchase,
or exercise a

32

 

conversion right for, Common Stock at less than the applicable Closing Price
of the Common Stock, and in determining the aggregate exercise or conversion price payable
for such Common Stock, there shall be taken into account any consideration received by the
Company 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 Directors of the Company. Any
adjustment made pursuant to this Section 4.06(b) shall become effective on the date that is
immediately after the date fixed for the determination of shareholders entitled to receive
such rights, warrants, options, other securities or convertible securities. If any right,
warrant, option, other security or convertible security described in this Section 4.06(b) is
not exercised or converted prior to the expiration of the exercisability or convertibility
thereof, the new Conversion Reference Rate shall be readjusted to the Conversion Reference
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 Company distributes capital stock, evidences of indebtedness or other assets
or property of the Company to all holders of Common Stock, excluding:

     (1) dividends, distributions, rights, warrants, options, other securities or
convertible securities referred to in Section 4.06(a) or (b) above,

     (2) dividends or distributions paid exclusively in cash, and

     (3) Spin-Offs described below in this Section 4.06(c),

     then the Conversion Reference Rate will be adjusted based on the following formula:

	 	 	 	 	 	 
	 	CR1 =  
	 	CR0 x SP0
 

(SP0 – FMV)
	 	   

     where

	 	CR0 =	 	the Conversion Reference Rate in effect immediately prior to the adjustment relating to such event
	 
	 	CR1 =	 	the new Conversion Reference Rate taking such event into account
	 
	 	SP0 =	 	the Closing Price of the Common Stock on the Trading Day immediately
preceding the ex-dividend date for such distribution
	 
	 	FMV =	 	the fair market value (as determined in good faith by the Board of Directors of
the Company) of the capital stock, evidences of indebtedness, assets or property
distributed with respect to each outstanding share of Common Stock on the earlier of
the record date or the ex-dividend date for such distribution.

An adjustment to the Conversion Reference Rate made pursuant to the foregoing provisions of
this Section 4.06(c) shall be made successively whenever any such distribution is made and
shall become effective on the ex-dividend date for such distribution.

     If the Company distributes to all holders of Common Stock capital stock of any class or
series, or similar equity interest, of or relating to a subsidiary or other business unit of
the Com-

33

 

pany (a “Spin-Off”), the Conversion Reference Rate in effect immediately before the
close of business on the date fixed for determination of holders of Common Stock entitled to
receive such distribution will be adjusted based on the following formula:

	 	 	 	 	 	 
	 	CR1 =  
	 	CR0 x (FMV0 + MP0)
 

MP0
	 	   

     where

	 	CR0 =	 	the Conversion Reference Rate in effect immediately prior to the adjustment relating to such event
	 
	 	CR1 =	 	the new Conversion Reference Rate taking such event into account
	 
	 	FMV0 =	 	the average of the Closing Prices of the capital stock or similar equity
interest distributed to holders of Common Stock applicable to one share of Common Stock
over the first 10 consecutive Trading Days after the effective date of the Spin-Off
	 
	 	MP0 =	 	the average of the Closing Prices of the Common Stock over the first 10
consecutive Trading Days after the effective date of the Spin-Off.

     An adjustment to the Conversion Reference Rate made pursuant to the foregoing paragraph
will occur on the 10th Trading Day from and including the effective date of the Spin-Off;
provided that for any cash conversion with respect to any Security that has a Cash
Conversion Trigger Date within the 10 Trading Days from and including the effective date of
any Spin-Off, the Conversion Reference Rate for such Security shall be adjusted based on the
number of Trading Days between the effective date of such Spin-Off and the Cash Conversion
Trigger Date with respect to such Security.

     If any such dividend or distribution described in this Section 4.06(c) is declared but
not paid or made, the new Conversion Reference Rate shall be readjusted to be the Conversion
Reference Rate that would then be in effect if such dividend or distribution had not been
declared.

     (d) If the Company pays or makes any dividend or distribution consisting exclusively of
cash to all holders of Common Stock, the Conversion Reference Rate will be adjusted based on
the following formula:

	 	 	 	 	 	 
	 	CR1 =  
	 	CR0 x SP0
 

(SP0 – C)
	 	   

     where

	 	CR0 =	 	the Conversion Reference Rate in effect immediately prior to the adjustment relating to such event
	 
	 	CR1 = 	 	the new Conversion Reference Rate taking such event into account
	 
	 	SP0 =	 	the average of the Closing Prices of the Common Stock over the 10
consecutive Trading-Day period ending on the Trading Day immediately preceding the
ex-dividend date for such distribution

34

 

	 	C =	 	the amount in cash per share of Common Stock that the Company distributes to
holders of Common Stock.

     An adjustment to the Conversion Reference Rate made pursuant to this Section 4.06(d)
shall become effective on the ex-dividend date for such dividend or distribution. If any
dividend or distribution described in this Section 4.06(d) is declared but not so paid or
made, the new Conversion Reference Rate shall be readjusted to the Conversion Reference Rate
that would then be in effect if such dividend or distribution had not been declared.

     (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender
offer or exchange offer for Common Stock to the extent that the cash and value of any other
consideration included in the payment per share of Common Stock exceeds the Closing Price of
the Common Stock 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 Reference Rate will be adjusted based on the following formula:

	 	 	 	 	 	 	 
	   

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

SP1 x OS0
	 	   

     where

	 	CR0 =	 	the Conversion Reference Rate in effect immediately prior to the adjustment relating to such event
	 
	 	CR1 =	 	the new Conversion Reference Rate taking such event into account
	 
	 	AC =	 	the aggregate value of all cash and any other consideration (as determined by
the Board of Directors of the Company) paid or payable for Common Stock purchased in
such tender or exchange offer
	 
	 	OS0 =	 	the number of shares of Common Stock outstanding immediately prior to the
date such tender or exchange offer expires
	 
	 	OS1 =	 	the number of shares of Common Stock 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 Prices of Common Stock 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
Reference Rate, no adjustment to the Conversion Reference Rate will be made.

     Any adjustment to the Conversion Reference Rate made pursuant to this Section 4.06(e)
shall become effective on the date immediately following the determination of the average of
the Closing Prices of Common Stock for purposes of SP1 above. If the Company or
one of its Subsidiaries is obligated to purchase Common Stock pursuant to any such tender or
exchange offer but is permanently prevented by applicable law from effecting any such
purchase or all such pur-

35

 

chases are rescinded, the new Conversion Reference Rate shall be
readjusted to be the Conversion Reference Rate that would be in effect if such tender or
exchange offer had not been made.

     (f) [Reserved].

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

     (h) If the Company has in effect a rights plan while any Securities remain outstanding,
and if the rights provided for in the rights plan adopted by the Company have separated from
the Common Stock in accordance with the provisions of the applicable stockholder rights
agreement, the Conversion Reference Rate will be adjusted at the time of separation as if
the Company had distributed to all holders of Common Stock, capital stock, evidences of
indebtedness or other assets or property pursuant to Section 4.06(c) above, subject to
readjustment of the Conversion Reference Rate upon the subsequent expiration, termination
or redemption of the rights to be the Conversion Reference Rate that would be in effect had
such separation not occurred.

     (i) For purposes of this Section 4.06, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of
Common Stock.

     Section 4.07. No Adjustment.

     (a) The Company shall not be required to make any adjustment to the Conversion Reference Rate
in accordance with the provisions of Section 4.06 if Holders of the Securities are permitted to
participate, on an as-converted basis (i.e., as though each Holder had exchanged each
$1,000 principal amount of its Securities immediately prior to the record date of or the date to
determine the Persons entitled to participate in such distribution or other transaction for a
number of shares of Common Stock equal to the Conversion Reference Rate at such time), in the
transactions described in Section 4.06.

     (b) No adjustment in the Conversion Reference Rate shall be required to be made unless the
adjustment would require an increase or decrease of at least 1% of the Conversion Reference Price.
If the adjustment is not made because the adjustment does not change the Conversion Reference Price
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 1/10,000th
of a share, as the case may be. Notwithstanding the foregoing, all adjustments not previously made
shall have effect with respect to any cash conversion of Securities that is made prior to the time
such adjustment is made, as if such adjustment had been made.

36

 

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

     (d) Notwithstanding anything in this Section 4.07 to the contrary, in no event shall the
Conversion Reference Rate be adjusted so that the Conversion Reference Price would be less than
$0.01.

     Section 4.08. Notice of Adjustment.

     Whenever the Conversion Reference Rate is adjusted as herein provided, the Company shall
promptly file with the Trustee and any Paying Agent other than the Trustee, an Officer’s
Certificate setting forth the Conversion Reference Rate after such adjustment and setting forth a
brief statement of the facts requiring such adjustment. Unless and until a Trust Officer of the
Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have
knowledge of any adjustment of the Conversion Reference Rate and may assume that the last
Conversion Reference Rate of which it has knowledge is still in effect. Promptly after delivery of
such certificate, the Company shall prepare a notice of such adjustment of the Conversion Reference
Rate setting forth the adjusted Conversion Reference Rate and the date on which each adjustment
becomes effective and shall mail such notice of such adjustment of the Conversion Reference Rate to
Holders 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.

     Section 4.09. Notice of Certain Transactions.

     In the event that the Company takes any action which would require an adjustment to the
Conversion Reference Rate, the Company takes any action that requires the execution of a
supplemental indenture in accordance with the provisions of Section 4.10 or if there is a
dissolution or liquidation of the Company, the Company shall mail to Holders and file with the
Trustee a notice stating the proposed record or effective date, as the case may be. If reasonably
practicable, the Company shall mail such notice at least 20 days before such proposed effective
date. Failure to mail such notice or any defect therein shall not affect the validity of any
transaction referred to in this Section 4.09.

     Section 4.10. Effect of Reclassification, Consolidation, Merger
or Sale on Conversion Privilege.

     (a) If any of following events occur (each, a “Business Combination”), namely:

     (1) any recapitalization, reclassification or change of the Common Stock, other than
(A) a change in par value, or from par value to no par value, or from no par value to par
value, or (B) as a result of subdivision or a combination,

     (2) a consolidation, merger or combination of the Company with another Person,

37

 

     (3) a sale, lease or other transfer to a third Person of all or substantially all of
the consolidated assets of the Company and its Subsidiaries, or

     (4) any statutory share exchange of the Company with another Person,

in each case as a result of which holders of Common Stock are entitled to receive stock, other
securities, other property or assets (including cash or any combination thereof) with respect to or
in exchange for Common Stock, the Company or the successor or purchasing corporation, as the case
may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as
in force at the date of execution of such supplemental indenture if such supplemental indenture is
then required to so comply) providing that from and after the effective date of such Business
Combination, upon cash conversion of Securities, the cash settlement of the Conversion Reference
Value in accordance with the provisions of Section 4.12 shall be based on the value over the
applicable Conversion Reference Period of the shares of stock, other securities or other property
or assets (including cash or any combination thereof) which holders of Common Stock are entitled to
receive in respect of each share of Common Stock upon such Business Combination. For purposes of
the foregoing, where a Business Combination involves a transaction
that causes the Common Stock to be converted into the right to receive more than a single type of
consideration based upon any form of stockholder election, such consideration will be deemed to be
the weighted average of the types and amounts of consideration received by the holders of Common
Stock that affirmatively make such an election. If, in the case of any such Business Combination,
the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock
includes shares of stock or other securities and assets of a corporation other than the successor
or purchasing corporation, as the case may be, in such Business Combination, then such supplemental
indenture shall also be executed by such other corporation and shall contain such additional
provisions to protect the interests of the Holders of the Securities as the Board of Directors
shall reasonably consider necessary by reason of the foregoing, including to the extent practicable
the provisions providing for the repurchase rights set forth in Article 3 hereof. The Company
shall not become a party to any Business Combination unless its terms are materially consistent
with the provisions of this Section 4.10. The above provisions of this Section 4.10 shall
similarly apply to successive Business Combinations. None of the provisions of this Section 4.10
shall affect the right of a Holder of Securities to require the Company to cash convert its
Securities in accordance with the provisions of this Article 4 prior to the effective date of a
Business Combination.

     If this Section 4.10(a) applies to any event or occurrence, Section 4.06 hereof shall not
apply to the extent the application of such Section would result in a duplicative adjustment.

     (b) In the event the Company shall execute a supplemental indenture pursuant to this Section
4.10, the Company shall promptly file with the Trustee (1) an Officer’s Certificate briefly stating
the reasons therefore and that all conditions precedent have been complied with and (2) an Opinion
of Counsel to the effect that all conditions precedent thereto and hereunder have been complied
with, and shall promptly mail notice of the execution of such supplemental indenture to all
Holders. Failure to mail such notice or any defect therein shall not affect the validity of such
transaction and such supplemental indenture.

     Section 4.11. Trustee’s Disclaimer.

     (a) Neither the Trustee nor any Agent shall have any duty to calculate the Conversion
Reference Price or to make any computation or determination in connection therewith or to determine
when an adjustment under this Article 4 should be made, how it should be made or what such
adjustment should be, but may accept as conclusive evidence of the same or the correctness of any
such adjustment, and shall be protected in relying upon, an Officer’s Certificate and Opinion of
Counsel, including the Offi-

38

 

cer’s Certificate with respect thereto which the Company is obligated to
file with the Trustee pursuant to Section 4.08. Neither the Trustee nor any Agent makes any
representation as to the validity or value of any securities or assets issued upon conversion of
Securities, and neither the Trustee nor any Agent shall be responsible for the Company’s failure to
comply with any provisions of this Article 4, including whether or not a supplemental indenture is
required to be executed.

     (b) The Trustee shall not be under any responsibility to determine the correctness of any
provisions contained in any supplemental indenture executed pursuant to Section 4.10, but may
accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying
upon, the Officer’s Certificate and Opinion of Counsel, with respect thereto which the Company is
obligated to file with the Trustee pursuant to Section 4.10.

     (c) Neither the Trustee nor any Paying Agent or any other Agent shall be responsible for
determining whether any event contemplated by this Article 4 has occurred which makes the
Securities eligible for cash conversion until the Company has delivered to the Trustee and any
Paying Agent and each other Agent an Officer’s Certificate stating that such event has occurred, on
which Officer’s Certificate the Trustee and any such Paying Agent and other Agent may conclusively
rely, and the Company agrees to deliver such Officer’s Certificate to the Trustee and any such Paying Agent and each other
Agent promptly after the occurrence of any such event.

     Section 4.12. Settlement Upon Cash Conversion.

     (a) Holders surrendering Securities for cash conversion shall be entitled to receive, for each
$1,000 principal amount of Securities surrendered for cash conversion, cash in an amount equal to
the Conversion Reference Value for the applicable Conversion Reference Period, appropriately
adjusted to reflect events occurring during such Conversion Reference Period that would result in
an adjustment to Conversion Reference Rate in accordance with the provisions of Section 4.06. The
Company will deliver such cash to such Holder in accordance with Section 4.02(a), and such delivery
shall be deemed to satisfy the Company’s obligation to pay the principal amount and all accrued and
unpaid interest on the Securities so cash converted. The Company shall determine the Conversion
Reference Value at the end of the applicable Conversion Reference Period and shall notify the
Trustee and the Paying Agent.

     (b) In the event that the Conversion Reference Value with respect to any $1,000 principal
amount of Securities cash converted following the 45th Scheduled Trading Day prior to the Final
Maturity Date would be less than $1,000, in lieu of the Conversion Reference Value, the Company
will pay to the converting Holder $1,000 on the Final Maturity Date.

     (c) For the purposes of Section 4.12(a), in the event that any of Conversion Reference Value,
Daily Conversion Reference Value, or Volume Weighted Average Price is not calculable for all
portions of the Conversion Reference Period, the Company’s Board of Directors shall in good faith
determine the values necessary to calculate the Conversion Reference Value, Daily Conversion
Reference Value, and Volume Weighted Average Price (which calculations shall be evidenced by an
Officer’s Certificate delivered to the Trustee).

ARTICLE 5

COVENANTS

     Section 5.01. Payment of Securities.

     (a) The Company shall promptly make all payments in respect of the Securities on the dates and
in the manner provided in the Securities and this Indenture. A payment of principal, interest,
Fundamental Change Purchase Price or the Conversion Reference Value shall be considered paid on the
date it is due if the Paying Agent (other than the Company) (or if the Company is the Paying Agent,
the segregated account or separate trust fund maintained by the Company pursuant to Section 2.04)
holds by 10:00 a.m., New York City time, on that date money, deposited by or on behalf of the
Company sufficient to make the payment. Accrued and unpaid interest on any Security that is
payable (whether or not punctually paid or duly provided for) on any Interest Payment Date shall be
paid to the Person in whose name that Security is registered at the close of business on the
Regular Record Date for such interest at the office or agency of the Company maintained for such
purpose. The Company shall, to the fullest extent permitted by law, pay interest in immediately
available funds on overdue principal and interest at the annual rate borne by the Securities
compounded semiannually, which interest shall accrue from the date such overdue amount was
originally due to the day preceding the date payment of such amount, including interest thereon,
has been made or duly provided for.

     (b) Payment of the principal of and interest, if any, on the Securities, and the Conversion
Reference Value and Fundamental Change Purchase Price with respect thereto shall be made at the
office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City
of New York (which shall initially be the Corporate Trust Office of the Trustee) in such coin or
currency of the United States of America as at the time of payment is legal tender for payment of
public and private debts; provided, however, that at the option of the Company payment of interest
on any Certificated Securities having an aggregate principal amount of $5,000,000 or less may be
made by check mailed to the address of the Person entitled thereto as such address appears in the
Register; provided further that a Holder of a Certificated Security having an aggregate principal
amount of more than $5,000,000 will be paid by wire transfer in immediately available funds at the
election of such Holder if such Holder has provided wire transfer instructions to the Trustee at
least 10 Business Days prior to the payment date. Any wire transfer instructions received by the
Trustee will remain in effect until revoked by the Holder. In the case of a permanent Global
Security, interest payable on any applicable payment date will be paid to the Depositary, with
respect to that portion of such permanent Global Security held for its account by Cede & Co. for
the purpose of permitting such party to credit the interest received by it in respect of such
permanent Global Security to the accounts of the beneficial owners thereof.

     Section 5.02. Reports by Company and the Guarantors.

     (a) Whether or not required by the rules and regulations of the SEC, the Company shall deliver
to the Trustee, within 15 days after the date such reports would be required to be filed with the
SEC if the Company were required to file such reports pursuant to Section 13 or 15(d) of the
Exchange Act, copies of all annual and quarterly reports and of the information, documents and
other reports (or copies of such portions of any of the foregoing as the SEC may by rules and
regulations prescribe) that it would be required to file with the SEC pursuant to Section 13 or
15(d) of the Exchange Act if the Company were required to file such reports. To the extent
required by law or the rules and regulations of the SEC, the Company also shall comply with the
provisions of TIA Section 314(a).

40

 

     (b) For so long as any Restricted Securities are outstanding, the Company agrees that, in
order to render such Restricted Securities eligible for resale pursuant to Rule 144A under the
Securities Act,
it will make available, upon request, to any Holder of Restricted Securities or prospective
purchasers of Restricted Securities the information specified in Rule 144A(d)(4), unless the
Company files or furnishes such information to the SEC pursuant to Section 13 or 15(d) of the
Exchange Act.

     (c) Delivery of such reports 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 compliance by
each of the Company and the Guarantors with any of its covenants hereunder (as to which the Trustee
is entitled to rely exclusively on Officer’s Certificates).

     Section 5.03. Compliance Certificates.

     The Company shall deliver to the Trustee, within one hundred twenty (120) days after the end
of each fiscal year of the Company (beginning with the fiscal year ending December 31, 2008), an
Officer’s Certificate as to the signer’s knowledge of the Company’s compliance with all conditions
and covenants on its part contained in this Indenture and stating whether or not the signer knows
of any Default or Event of Default. If such signer knows of such a Default or Event of Default,
the Officer’s Certificate shall describe the Default or Event of Default and the efforts to remedy
the same. For the purposes of this Section 5.03, compliance shall be determined without regard to
any grace period or requirement of notice provided pursuant to the terms of this Indenture. Such
certificates need not comply with Section 12.04 of this Indenture.

     The Company shall deliver to the Trustee, as soon as possible and in any event within five
days after the Company becomes aware of the occurrence of any Default or Event of Default an
Officer’s Certificate setting forth the details of such Default or Event of Default and the action
which the Company proposes to take with respect thereto.

     Section 5.04. Further Instruments and Acts.

     Upon request of the Trustee, the Company and the Guarantors will execute and deliver such
further instruments and do such further acts as may be reasonably necessary or proper to carry out
more effectively the purposes of this Indenture.

     Section 5.05. Maintenance of Corporate Existence.

     Subject to Article 6, the Company will do or cause to be done all things necessary to preserve
and keep in full force and effect its corporate existence.

     Section 5.06. Stay, Extension and Usury Laws.

     The Company covenants (to the extent that they 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 Company from paying
all or any portion of the principal of or accrued but unpaid interest on the Securities 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 Company (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

41

 

impede the execution of any power herein granted
to the Trustee, but will suffer and permit the execution of every such power as though no such law
had been enacted.

     Section 5.07. Maintenance of Office or Agency.

     The Company shall maintain an office or agency where Securities may be presented or
surrendered for payment. The Company also will maintain an office or agency where Securities may
be surrendered for registration of transfer or exchange and where notices and demands to or upon
the Company in respect of the Securities and this Indenture may be served. The office of the
Trustee, at its Corporate Trust Office, will be such office or agency of the Company, unless the
Company shall designate and maintain some other office or agency for one or more of such purposes.
The Company will give prompt written notice to the Trustee of the location and any change in the
location of any such offices or agencies. If at any time the Company shall fail to maintain any
such required offices or agencies or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the office of the
Trustee and the Company hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands.

     The Company may from time to time designate one or more other offices or agencies (in or
outside of The City of New York) where the Securities may be presented or surrendered for any or
all such purposes, and may from time to time rescind such designation. The Company will give
prompt written notice to the Trustee of any such designation or rescission and any change in the
location of any such office or agency.

     Section 5.08. Guarantees.

     If any Domestic Subsidiary of the Company (including any Domestic Subsidiary of the Company
formed or acquired after the Issue Date) that is not a Guarantor shall become a guarantor of the
Company’s obligations under the Senior Credit Facility, other Credit Facility Debt or any Capital
Markets Debt, then such Domestic Subsidiary shall (i) execute and deliver to the Trustee a
supplemental indenture pursuant to which such Domestic Subsidiary shall unconditionally Guarantee
all of the Company’s obligations under the Securities and this Indenture on the terms set forth in
Article 11 and (ii) deliver to the Trustee an Opinion of Counsel to the effect that such
supplemental indenture has been duly authorized, executed and delivered by such Domestic Subsidiary
and constitutes a legal, valid, binding and enforceable obligation of such Domestic Subsidiary,
subject to customary exceptions. Such opinion need not comply with Section 12.04 of this
Indenture.

(if other than the Company) shall be a corporation or limited liability company organized
and validly existing under the laws of the United States of America or any State thereof or
the District of

42

 

Columbia, and shall, in any such case, expressly assume by a supplemental
indenture, the due and punctual payment of the principal of and interest on all the
Securities and the performance and observance of every covenant of this Indenture to be
performed or observed on the part of the Company;

     (2) after giving effect to the transaction, no Default or Event of Default shall have

Certificate and an Opinion of Counsel, each stating that such transaction complies with this
Article 6.01 and, if a supplemental indenture is required in connection with such
transaction, such supplemental indenture complies with this Article, and that all conditions
precedent herein provided for relating to such transaction have been complied with.

     Section 6.02. Successor Substituted.

     Upon any consolidation of the Company with, or merger of the Company into, any other Person or
any sale, conveyance, assignment, transfer, lease or other disposition of all or substantially all
of the Company’s assets in accordance with Section 6.01, the successor Person formed by such
consolidation or into which the Company is merged or to which such sale, conveyance, assignment,

exercise every right and power of, the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein, and thereafter, except in the case of a
lease, the predecessor Person shall be relieved of all obligations and covenants under this
Indenture and the Securities.

ARTICLE 7

DEFAULT AND REMEDIES

     Section 7.01. Events of Default.

     (a) An “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):

receipt by the Company of a Notice of Default specifying such failure; or

     (6) one or more defaults shall have occurred under any of the agreements, indentures or
instruments under which the Company or any Significant Subsidiary of the Company then has
outstanding indebtedness in excess of $50 million, individually or in the aggregate, and
either:

     (A) such default results from the failure to pay such indebtedness at its
stated final maturity and such default has not been cured or the indebtedness repaid
in full within ten days of the default; or

     (B) such default or defaults have resulted in the acceleration of the maturity
of such indebtedness and such acceleration has not been rescinded or such
indebtedness repaid in full within ten days of the acceleration;

     (7) one or more judgments or orders that exceed $50 million in the aggregate (net of
amounts covered by insurance or bonded) for the payment of money have been entered by a

full force and effect and enforceable in accordance with its terms, except to the extent

constitute an Event of Default under this Section 7.01(a)(9); or

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

44

 

     (A) is for relief against the Company or any Subsidiary of the Company that is

aggregate principal amount of the Securities then Outstanding notify the Company and the Trustee in
writing, of the Default (a “Notice of Default”), and the Company does not cure the Default within
the time specified in clause (5) of Section 7.01(a), or obtain a waiver, after receipt of such
notice. A notice given pursuant to this Section 7.01 shall be given by registered or certified
mail, must specify the Default, demand that it be remedied and state that the notice is a Notice of
Default. When any Default under this Section 7.01 is cured, it ceases.

     (c) The Company will deliver to the Trustee, within 30 days after becoming aware of the
occurrence of a Default or Event of Default, written notice thereof.

Indenture, the Trustee or the Holders of not less than 25% in aggregate principal amount of the
Securities then Outstanding may, and the Trustee at the request of such Holders shall, declare all
unpaid principal of and accrued interest on all Securities to be due and payable, by a notice in
writing to the Company (and to the Trustee if given by the Holders of the Securities). Upon any
such declaration, such principal and interest shall become due and payable immediately. If an
Event of Default specified in clause (9) or (10) of Section 7.01(a) occurs and is continuing with
respect to the Company, then all the Securities shall ipso facto become and be due and payable
immediately in an amount equal to the principal amount of the Securities, together with accrued and
unpaid interest, if any, to the date the Securities become due and payable, without any declaration
or other act on the part of the Trustee or any Holder. Thereupon, the Trustee may, at its
discretion, proceed to protect and enforce the rights of the Holders of the Securities by
appropriate judicial proceedings.

     (b) After a declaration of acceleration with respect to the Securities, but before a judgment
or decree for payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in aggregate principal amount of the Securities
Outstanding, by written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if:

45

 

     (i) the Company has paid or deposited with the Trustee a sum sufficient to pay

     (1) all sums paid or advanced by the Trustee under this Indenture and the
reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel,

     (2) all overdue interest on all Outstanding Securities,

     (3) the principal of any Outstanding Securities which have become due otherwise
than by such declaration of acceleration and interest thereon at the rate borne by
the Securities, and

     (4) to the extent that payment of such interest is lawful, interest upon
overdue interest at the rate borne by the Securities;

     (ii) the rescission would not conflict with any judgment or decree of a court of
competent jurisdiction; and

     (iii) all Defaults or Events of Default, other than the non-payment of principal of and
interest on the Securities which have become due solely by such declaration of acceleration,
have been cured or waived as provided in Section 7.13. No such rescission shall affect any
subsequent Default or impair any right consequent thereon.

     (c) Notwithstanding clause (a) of this Section 7.02, to the extent elected by the Company,
except as provided in clauses (d) and (e) below, the sole remedy for an Event of Default relating
to the failure by the Company to comply with the provisions of Section 5.02 of this Indenture
shall, 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 Securities at an annual rate
equal to 0.50% of the principal amount of the Securities. Such Special Interest shall be paid
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 began to accrue on the Securities. Special
Interest shall accrue on all Outstanding Securities from and including the date on which an Event
of Default relating to a failure to comply with the provisions of Section 5.02 shall first occur 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 the Event of Default relating
to the failure to comply with Section 5.02 is cured or waived prior to such 365th day), such
Special Interest shall cease to accrue and, if the Event of Default relating to the failure to
comply with Section 5.02 shall not have been cured or waived prior to such 365th day, the
Securities shall be subject to acceleration as provided in this Section 7.02. Delivery by the
Company of any report or other information required to be filed or otherwise delivered by it
pursuant to Section 5.02 shall constitute a cure of any failure to file or otherwise deliver such
report pursuant to Section 5.02. The provisions of 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 Company
shall not elect to pay Special Interest upon an Event of Default resulting from the failure of the
Company to comply with the provisions of Section 5.02, the Securities shall be subject to
acceleration as provided above in this Section 7.02.

     If the Company shall elect to pay Special Interest in connection with an Event of Default
relating to its failure to comply with the requirements of Section 5.02, (1) the Company shall
notify all Holders 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 shall first occur, and (2) all references
herein to interest accrued or payable as of

46

 

any date shall include any Special Interest accrued or
payable as of such date as provided in this Section 7.02.

     (d) Subject to clause (g) of this Section 7.02, if, at any time during the six-month period
beginning on, and including, the date which is six months after the Issue Date and ending on the
date which is the one-year anniversary of the Issue Date, the Company fails to timely file any
document or report that the Company is required to file with the SEC pursuant to Section 13 or
15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods
thereunder and other than current reports on
Form 8-K), or the Securities are not otherwise freely tradable by Holders other than the
Company’s Affiliates as a result of restrictions pursuant to U.S. securities law or the terms of
this Indenture or the Securities, the Company shall pay additional interest (“Additional Interest”)
on the Securities which shall accrue on the Securities at a rate of 0.25% per annum of the
principal amount of Securities outstanding for each day during such period for which the Company’s
failure to file, or the failure of the Securities to be freely tradable, as described above, has
occurred and is continuing, which rate shall be increased by an additional 0.25% per annum
following the 90th day on which such Additional Interest has commenced accruing, provided that the
rate at which such Additional Interest under this Section 7.02(d) accrues may in no event exceed
0.50% per annum; and provided further that the Company shall have 14 calendar days, in the
aggregate, to cure any such late filings or failures of the Securities to be freely tradable before
any such Additional Interest shall accrue.

     (e) Following the one-year anniversary of the Issue Date, if, and for so long as, the
restrictive legend on the Securities has not been removed in accordance with Section 2.07 or
Section 2.18 or the Securities are not otherwise freely tradable by Holders other than the
Company’s Affiliates without restrictions pursuant to U.S. securities laws or the terms of this
Indenture or the Securities, the Company shall pay Additional Interest on the Securities which
shall accrue on the Securities at a rate of 0.25% per annum of the principal amount of Securities
outstanding for each day after the one-year anniversary of the Issue Date of any Securities until
the restrictive legend on the Securities has been removed and the Securities are otherwise freely
tradable by Holders other than the Company’s Affiliates without restrictions pursuant to U.S.
securities law or the terms of this Indenture or the Securities, which rate shall be increased by
an additional 0.25% per annum following the 90th day on which such Additional Interest has
commenced accruing, provided that the rate at which such Additional Interest under this Section
7.02(e) accrues may in no event exceed 0.50% per annum; and provided further that the Company shall
have 14 calendar days, in the aggregate, to remove the restricted securities legend or otherwise
cause the Securities to be freely tradeable before any such Additional Interest shall accrue.

     (f) Additional Interest payable in accordance with Sections 7.02(d) and/or 7.02(e) shall be
payable in arrears on each Interest Payment Date for the Securities following accrual in the same
manner as regular interest on the Securities. All references herein to interest accrued or
payable as of any date shall include any Additional Interest accrued or payable as of such date as
provided in this Section 7.02.

     (g) Notwithstanding the foregoing, if the Company is required to pay Additional Interest
pursuant to this Section 7.02, the Company shall have the right, in its sole discretion, to
designate an effective shelf registration statement for the resale by the Holders of the Securities
or, to the extent permitted by applicable U.S. securities laws, consummate a registered exchange
offer for the Securities. Additional Interest shall not accrue for each day on which such
registration statement remains effective and usable by Holders for the resale of the Securities or
following consummation of such exchange offer, as applicable. Any such registration or exchange
offer shall be effected on terms customary for securities generally offered in reliance upon Rule
144A under the Securities Act.

47

 

     Section 7.03. Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if:

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

     (b) default is made in the payment of (i) the principal of any Security at the Stated
Maturity thereof or (ii) the Fundamental Change Purchase Price of any Security required to
be purchased on any Fundamental Change Purchase Date, or

     (c) default is made in the payment of the Conversion Reference Value of any Security
when required to be paid pursuant to Section 4.02 and such default continues for a period of
15 days,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such
Securities, the whole amount then due and payable on such Securities for principal and interest and
Conversion Reference Value and Fundamental Change Purchase Price and, to the extent that payment of
such interest shall be legally enforceable, interest upon overdue principal and installments of
interest, at the rate borne by the Securities; and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

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

     If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders under this Indenture or any Guarantee
by such appropriate private or judicial proceedings as the Trustee shall deem most effectual to
protect and enforce such rights, whether for the specific enforcement of any covenant or agreement
in this Indenture or in any Guarantee or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy, subject however to Section 7.12. No recovery of any such judgment
upon any property of the Company or any Guarantor shall affect or impair any rights, powers or
remedies of the Trustee or the Holders.

     Section 7.04. Trustee May File Proofs of Claim.

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

     (a) to file and prove a claim for the whole amount of principal and interest owing and
unpaid in respect of the Securities and to file such other papers or documents as may be
nec-

48

 

essary or advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel) and of the Holders allowed in such judicial proceeding, and

     (b) to collect and receive any moneys or other property payable or deliverable on any
such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any
such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments directly to the
Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 8.07.

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

     Section 7.05. Trustee May Enforce Claims Without Possession of Securities.

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

     Section 7.06. Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article 7 or otherwise on behalf of the
Holders or the Trustee pursuant to this Article 7 or through any proceeding or any arrangement or
restructuring in anticipation or in lieu of any proceeding contemplated by this Article 7 and any
money or other property distributable in respect of the Company’s obligations under this Indenture
after an Event of Default shall be applied, subject to applicable law, in the following order, at
the date or dates fixed by the Trustee and, in case of the distribution of such money on account of
principal, Conversion Reference Value, Fundamental Change Purchase Price or interest, upon
presentation of the Securities and the notation thereon of the payment if only partially paid and
upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee (or any predecessor trustee)
under Section 8.07;

     SECOND: To the payment of the amounts then due and unpaid upon the Securities for
principal, Conversion Reference Value, Fundamental Change Purchase Price and interest, in
respect of which or for the benefit of which such money has been collected, ratably, without
preference or priority of any kind, according to the amounts due and payable on such
Securities for principal, Conversion Reference Value, Fundamental Change Purchase Price and
interest; and

49

 

     THIRD: The balance, if any, to the Person or Persons entitled thereto, including the
Company, provided that all sums due and owing to the Holders and the Trustee have been paid
in full as required by this Indenture.

     Section 7.07. Limitation on Suits.

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

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

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

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

     (d) the Trustee for 15 days after its receipt of such notice, request and offer (and if
requested, provision) of indemnity has failed to institute any such proceeding; and

     (e) no direction inconsistent with such written request has been given to the Trustee
during such 15-day period by the Holders of a majority in principal amount of the
Outstanding Securities;

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

     Section 7.08. Unconditional Right of Holders To Receive Payment and To Cash Convert.

     Notwithstanding any other provision of this Indenture, the right of any Holder of a Security
to receive payment of the principal amount, interest or Fundamental Change Purchase Price, if any,
in respect of the Securities held by such Holder, on or after the respective due dates expressed in
the Securities and this Indenture (whether upon repurchase or otherwise), and to cash convert such
Security in accordance with Article 4, and to bring suit for the enforcement of any such payment on
or after such respective due dates or for the right to cash convert in accordance with Article 4,
is absolute and unconditional and shall not be impaired or affected without the consent of the
Holder.

     Section 7.09. Restoration of Rights and Remedies.

     If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee or to such Holder, then and in every such case the
Company, any other obligor on the Securities, the Trustee and the Holders shall, subject to any
determination in such proceed-

50

 

ing, be restored severally and respectively to their former positions
hereunder, and thereafter all rights and remedies of the Trustee and the Holders shall continue as
though no such proceeding had been instituted.

     Section 7.10. Rights and Remedies Cumulative.

     No right or remedy herein conferred upon or reserved to the Trustee or to the Holders is
intended to be exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

     Section 7.11. Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Security to exercise any right or
remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by
this Article 7 or by law to the Trustee or to the Holders may be exercised from time to time, and
as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

     Section 7.12. Control by Holders.

     The Holders of not less than a majority in aggregate principal amount of the Outstanding
Securities shall have the right to direct the time, method and place of conducting any proceeding
for exercising 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, expose the Trustee to personal liability, or be unduly prejudicial to Holders not
joining therein; and

     (b) subject to the provisions of Section 315 of the TIA (which shall be applicable
hereunder), the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

     Section 7.13. Waiver of Past Defaults.

     Subject to Section 7.08, the Holders of a majority in aggregate principal amount of the
Securities then Outstanding by notice to the Trustee may waive an existing Default or Event of
Default and its consequences, except an uncured Default or Event of Default in the payment of the
principal of or any accrued but unpaid interest on any Security or Fundamental Change Purchase
Price, an uncured failure by the Company to cash convert any Securities, or any Default or Event of
Default in respect of any provision of this Indenture or the Securities which, under Section 10.02,
cannot be modified or amended without the consent of the Holder of each Security affected. When a
Default or Event of Default is waived, it is cured and ceases to exist.

     Section 7.14. Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof
shall be deemed to have agreed, that any court may in its discretion require, in any suit for the
enforce-

51

 

ment of any right or remedy under this Indenture, or in any suit against the Trustee for any
action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit
of an undertaking to pay the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by such party
litigant, but the provisions of this Section shall not apply to any suit instituted by the Trustee,
to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10%
in principal amount of the Outstanding Securities, or to any suit instituted by any Holder for the
enforcement of the payment of the principal of or interest on, any Security on or after the
respective Stated Maturities expressed in such Security (or, in the case of purchase pursuant to
Article 3 hereof, on the Fundamental Change Purchase Date) or for the enforcement of its right to
cash convert its Securities in accordance with Article 4.

     Section 7.15. Remedies Subject to Applicable Law.

     All rights, remedies and powers provided by this Article 7 may be exercised only to the extent
that the exercise thereof does not violate any applicable provision of law in the premises, and all
the provisions of this Indenture are intended to be subject to all applicable mandatory provisions
of law which may be controlling in the premises and to be limited to the extent necessary so that
they will not render this Indenture invalid, unenforceable or not entitled to be recorded,
registered or filed under the provisions of any applicable law.

ARTICLE 8

TRUSTEE

     Section 8.01. Duties of Trustee.

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

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

     (1) the Trustee undertakes to perform those duties and only those duties as are
specifically set forth in this Indenture, and no implied covenants or obligations shall be
read into this Indenture against the Trustee; and

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

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

     (1) this clause (c) does not limit the effect of clause (b) or (d) of this Section
8.01;

52

take in good faith in accordance with a direction of the Holders of a majority in principal
amount of Outstanding Securities 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) No provision of this Indenture shall require the Trustee to expend or risk its own funds
or otherwise incur any financial liability in the performance of any of its duties hereunder, or in
the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is not reasonably
assured to it;

     (e) Whether or not therein expressly so provided, every provision of this Indenture that in
any way relates to the Trustee is subject to clauses (a), (b), (c), (d) and (f) of this Section
8.01; and

     Within 90 days after the occurrence of any Default, the Trustee shall transmit by mail to all
Holders and any other Persons that would be or are entitled to receive reports in accordance with
Section 313(c) of the TIA, as their names and addresses appear in the Security Register, notice of
such Default hereunder known to the Trustee, unless such Default shall have been cured or waived;
provided, however, that, except in the case of a Default in the payment of the principal of or
interest on any Security or the failure to deliver amounts owing upon cash conversion of a Security
in accordance with the provisions of Article 4 or in the failure to pay any Fundamental Change
Purchase Price, the Trustee shall be protected in withholding such notice if and so long as a trust
committee of Trust Officers of the Trustee in good faith determines that the withholding of such
notice is in the interest of the Holders.

     Section 8.03. Certain Rights of Trustee.

     Subject to the provisions of Section 8.01 hereof:

     (a) the Trustee may conclusively rely and shall be fully protected in acting or

security or other paper or document, but the Trustee, in its discretion, may make such
further inquiry or investigation into such facts or matters as it may deem fit, and, if the
Trustee shall determine to make such further inquiry or investigation, it shall be entitled

attorney at the sole cost of the Company and shall incur no liability or additional
liability of any kind by reason of such inquiry or investigation;

Indenture and the Securities;

     (i) the permissive rights of the Trustee enumerated herein shall not be construed as
duties of the Trustee;

     (j) whenever in the administration of this Indenture the Trustee shall deem it

in the absence of bad faith on its part, conclusively rely upon an Officer’s Certificate;

     (k) the rights, privileges, protections, immunities and benefits given to the Trustee,

54

 

ized to sign an Officer’s Certificate, including any person specified as so
authorized in any such certificate previously delivered and not superseded; and

     (m) the Trustee shall not be responsible or liable for any failure or delay in the

     Section 8.04. Trustee Not Responsible for Recitals, Dispositions of Securities or Application of Proceeds Thereof.

     The recitals contained herein and in the Securities, except the Trustee’s certificates of
authentication, shall be taken as the statements of the Company, and the Trustee assumes no

or any other capacity, may become the owner or pledgee of Securities, with the same rights it would
have if it were not the Trustee, Paying Agent, Registrar or such other agent and, subject to the
requirements that would be or are applicable pursuant to TIA Sections 310 and 311, may otherwise
deal with the Company and receive, collect, hold and retain collections from the Company with the
same rights it would have if it were not the Trustee, Paying Agent, Registrar or such other agent.

     Section 8.06. Money Held in Trust.

     All moneys received by the Trustee shall, until used or applied as herein provided, be held in
trust for the purposes for which they were received, but need not be segregated from other funds
except to the extent required by mandatory provisions of law.

     Section 8.07. Compensation and Indemnification of Trustee and Its Prior Claim.

     The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee
shall be entitled to, such compensation as the parties shall agree in writing from time to time for
all services rendered by it hereunder (which compensation shall not be limited by any provision of
law in regard to the compensation of a trustee of an express trust) and the Company covenants and
agrees to pay or reimburse the Trustee and each predecessor Trustee upon its request for all
reasonable expenses, disbursements and advances incurred or made by or on behalf of the Trustee in
accordance with any of the provisions of this Indenture (including the reasonable compensation and
the expenses and disbursements of its counsel and of all agents and other persons not regularly in
its employ) except any such expense, disbursement or advance as may arise from its gross negligence
or willful misconduct. The Company also covenants and agrees to indemnify the Trustee and each
predecessor Trustee for, and to hold it harmless

55

 

against, any claim, loss, liability, tax,
assessment or other governmental charge (other than taxes applicable to the Trustee’s compensation
hereunder) or expense incurred without gross negligence or willful misconduct on its part, arising
out of or in connection with the acceptance or administration of this Indenture or the trusts
hereunder and its duties hereunder, including enforcement of this Section 8.07 and also including
any liability which the Trustee may incur as a result of failure to withhold, pay or report any
tax, assessment or other governmental charge, and the costs and expenses of defending itself
against or investigating any claim or liability in connection with the exercise or performance of
any of its powers or duties hereunder. The obligations of the Company under this Section 8.07 to
compensate and indemnify the Trustee and each predecessor Trustee and to pay or reimburse the
Trustee and each predecessor Trustee for reasonable expenses, disbursements and advances shall
constitute an additional obligation hereunder and, together with the lien referred in the next
sentence, shall survive the satisfaction and discharge, and termination for any reason, of this
Indenture and the resignation or removal of the Trustee and each predecessor Trustee. To secure
the Company’s obligations in this Section 8.07, the Trustee shall have a lien prior to the
Securities on all money and property held or collected by the Trustee, other than money or property
held in trust for the payment of principal of or interest on particular Securities.

     “Trustee” for purposes of this Section shall include any predecessor Trustee; provided,
however, that the negligence, willful misconduct or bad faith of any Trustee hereunder shall not
affect the rights of any other Trustee hereunder.

     Without prejudice to its other rights hereunder, when the Trustee incurs expenses or renders
services in connection with an Event of Default specified in Section 7.01(a)(9) or Section
7.01(a)(10), the expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of administration under any applicable Federal or
State bankruptcy, insolvency or other similar law.

     Section 8.08. Conflicting Interests.

     The Trustee shall comply with the provisions of Section 310(b) of the TIA. For purposes of
Section 310(b)(1) of the TIA and to the extent permitted thereby, the Trustee, in its capacity as
trustee in respect of the Securities, shall not be deemed to have a conflicting interest arising
from its capacity as trustee in respect of the 1.25% Convertible Notes due 2012 issued pursuant to
the indenture dated as of March 7, 2007, among the Company, the guarantors named therein, and The
Bank of New York Mellon (formerly The Bank of New York), as trustee, or any indenture or indentures
pursuant to which other securities or certificates of interest or participation in other securities
of the Company are outstanding if the requirements for such exclusion set forth in said Section
310(b)(1) are met. If the TIA is then required by law or the rules and regulations of the SEC to
be applicable to this Indenture, nothing herein shall preclude the Trustee from making the
application referred to in the penultimate paragraph of Section 310(b) of the TIA.

     Section 8.09. Trustee Eligibility.

     There shall at all times be a Trustee hereunder which shall be eligible to act as trustee
under TIA Section 310(a) and which shall have a combined capital and surplus of at least
$50,000,000, to the extent there is an institution eligible and willing to serve. If the Trustee
does not have a Corporate Trust Office in The City of New York, the Trustee may appoint an agent in
The City of New York reasonably acceptable to the Company to conduct any activities which the
Trustee may be required under this Indenture to conduct in The City of New York. If such Trustee
publishes reports of condition at least annually, pursuant to law or to the requirements of
federal, state, territorial or District of Columbia supervising or examining authority, then for
the purposes of this Section 8.09, the combined capital and surplus of such cor-

56

 

poration 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 8.09, the Trustee shall resign immediately in the manner and with the
effect hereinafter specified in this Article 8.

     Section 8.10. Resignation and Removal; Appointment of Successor Trustee.

     (a) No resignation or removal of the Trustee and no appointment of a successor trustee
pursuant to this Article 8 shall become effective until the acceptance of appointment by the
successor trustee under Section 8.11.

     (b) The Trustee, or any trustee or trustees hereafter appointed, may at any time resign by
giving written notice thereof to the Company. Such resignation shall take effect upon the
appointment of a successor Trustee and the acceptance of such appointment by such successor
Trustee. If the instrument of acceptance by a successor Trustee required by Section 8.11 shall not
have been delivered to the Trustee within 30 days after the giving of such notice of resignation or
of any removal of the Trustee as hereinafter provided, the resigning or removed Trustee may
petition any court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities.

     (c) The Trustee may be removed at any time for any cause or for no cause by an Act of the
Holders of not less than a majority in aggregate principal amount of the Outstanding Securities,
delivered to the Trustee and to the Company.

     (d) If at any time:

     (1) the Trustee shall fail to comply with the provisions of TIA Section 310(b) after
written request therefor by the Company or by any Holder who has been a bona fide Holder of
a Security for at least six months,

     (2) the Trustee shall cease to be eligible under Section 8.09 and shall fail to resign
after written request therefor by the Company or by any Holder who has been a bona fide
Holder of a Security for at least six months, or

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

then, in any case, (i) the Company may remove the Trustee, or (ii) subject to Section 7.14, the
Holder of any Security who has been a bona fide Holder of a Security for at least six months may,
on behalf of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee
and appoint a successor trustee.

     (e) If the Trustee shall be removed or become incapable of acting, or if a vacancy shall occur
in the office of Trustee for any cause, the Company shall promptly appoint a successor trustee and
shall comply with the applicable requirements of Section 8.11. If, within 60 days after such
removal or incapability, or the occurrence of such vacancy, the Company has not appointed a
successor Trustee, a successor trustee shall be appointed by the Act of the Holders of a majority
in principal amount of the Outstanding Securities delivered to the Company and the retiring
Trustee. Such successor trustee so ap-

57

 

pointed shall forthwith upon its acceptance of such
appointment become the successor trustee. If no successor trustee shall have been so appointed by
the Company or the Holders of the Securities and accepted appointment in the manner hereinafter
provided, the Trustee or the Holder of any Security who has been a bona fide Holder for at least
six months may, subject to Section 7.14, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the appointment of a successor trustee.

     (f) The Company shall give notice of each resignation and each removal of the Trustee and each
appointment of a successor trustee by mailing written notice of such event by first-class mail,
postage prepaid, to the Holders of Securities as their names and addresses appear in the register
of the Registrar. Each notice shall include the name of the successor trustee and the address of
its Corporate Trust Office or agent hereunder.

     Section 8.11. Acceptance of Appointment by Successor.

     (a) Every successor trustee appointed hereunder shall execute, acknowledge and deliver to the
Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such successor trustee,
without any further act, deed or conveyance, shall become vested with all the rights, powers,
trusts and duties of the retiring Trustee as if originally named as Trustee hereunder; but,
nevertheless, on the written request of the Company or the successor trustee, upon payment of its
charges pursuant to Section 8.07 then unpaid, such retiring Trustee shall pay over to the successor
trustee all moneys at the time held by it hereunder, subject nevertheless to its lien provided for
in Section 8.07, and shall execute and deliver an instrument transferring to such successor trustee
all such rights, powers, trusts and duties. Upon request of any such successor trustee, the
Company shall execute any and all instruments for more fully and certainly vesting in and
confirming to such successor trustee all such rights and powers.

     (b) No successor trustee with respect to the Securities shall accept appointment as provided
in this Section 8.11 unless at the time of such acceptance such successor trustee shall be eligible
to act as trustee under the provisions of TIA Section 310(a) and this Article 8 and shall have a
combined capital and surplus of at least $50,000,000 and have a Corporate Trust Office or an agent
selected in accordance with Section 8.09.

     (c) Upon acceptance of appointment by any successor trustee as provided in this Section 8.11,
the Company shall give notice thereof to the Holders of the Securities, by mailing such notice to
such Holders at their addresses as they shall appear on the Security Register. If the acceptance
of appointment is substantially contemporaneous with the appointment, then the notice called for by
the preceding sentence may be combined with the notice called for by Section 8.10. If the Company
fails to give such notice within 10 days after acceptance of appointment by the successor trustee,
the successor trustee shall cause such notice to be given at the expense of the Company.

     Section 8.12. Merger, Conversion, Consolidation or Succession to Business.

     Any Person into which the Trustee may be merged or converted or with which it may be
consolidated, or any Person resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any Person succeeding to all or substantially all of the corporate
trust business of the Trustee (including the trust created by this Indenture) shall be the
successor of the Trustee hereunder, provided that such Person shall be eligible under TIA Section
310(a) and this Article 8 and shall have a combined capital and surplus of at least $50,000,000 and
have a Corporate Trust Office or an agent selected in accordance with Section 8.09, without the
execution or filing of any paper or any further act on the part of any of the parties hereto.

58

 

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

     Section 8.13. Preferential Collection of Claims Against Company.

     If and when the Trustee shall be or become a creditor of the Company (or other obligor under
the Securities), the Trustee shall be subject to the provisions of the TIA regarding the collection
of claims against the Company (or any such other obligor). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein, including, if the
TIA does not then apply to this Indenture, as if the TIA then applied to this Indenture.

     Section 8.14. Reports by Trustee.

     (a) Within 60 days after June 15 of each year commencing with the first June 15 after the
issuance of Securities, the Trustee, if so required under the TIA, including, if the TIA does not
then apply to this Indenture, as if the TIA then applied to this Indenture, shall transmit by mail
to all Holders, in the manner and to the extent provided in TIA Section 313(c), a brief report
dated as of such June 15 in accordance with and with respect to the matters required by TIA Section
313(a). The Trustee shall also transmit by mail to all Holders, in the manner and to the extent
provided in TIA Section 313(c), including, if the TIA does not then apply to this Indenture, as if
the TIA then applied to this Indenture, a brief report in accordance with and with respect to the
matters required by TIA Section 313(b)(2).

     (b) A copy of each report transmitted to Holders pursuant to this Section 8.14 shall, at the
time of such transmission, be mailed to the Company and filed with each national securities
exchange, if any, upon which the Securities are listed and if the TIA shall then apply to this
Indenture, also with the SEC. The Company will notify the Trustee promptly if the Securities are
listed on any national securities exchange.

ARTICLE 9

SATISFACTION AND DISCHARGE OF INDENTURE

     Section 9.01. Satisfaction and Discharge of Indenture.

     (a) This Indenture shall cease to be of further force and effect (except as to any surviving
rights of cash conversion, registration of transfer or exchange of Securities herein expressly
provided for and except as further provided below), and the Trustee, on demand of and at the
expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge
of this Indenture, when either:

     (1) all Securities theretofore authenticated and delivered (other than (i) Securities
which have been destroyed, lost or stolen and which have been replaced or paid as provided
in Section 2.08 and (ii) Securities for whose payment money has theretofore been deposited
in trust

59

 

and thereafter repaid to the Company as provided in Section 2.04) have been delivered
to the Trustee for cancellation; or

     (2) all such Securities not theretofore delivered to the Trustee for cancellation have
become due and payable, whether on the Final Maturity Date or a Fundamental Change Purchase
Date, upon cash conversion or otherwise,

provided that

     (i) the Company has deposited with the Trustee or a Paying Agent (other than the
Company or any of its Affiliates), immediately available funds, in trust for the purpose of
and in an amount sufficient to pay and discharge all indebtedness and obligations related to
such Securities not theretofore delivered to the Trustee for cancellation, for principal and
interest to the date of such deposit and/or for the payment of amounts due upon cash
conversion;

     (ii) the Company has paid or caused to be paid all other sums payable hereunder by the
Company; and

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

     (b) Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the
Company with respect to the Trustee under Section 8.07 and, if money shall have been deposited with
the Trustee pursuant to clause (2) of Section 9.01(a), the provisions of Sections 2.03, 2.04, 2.06,
2.07, 2.08, 2.13, 2.18 and 5.01 and this Article 9 shall survive until the Securities have been
paid in full.

     Section 9.02. Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 2.04, all United States dollars
deposited with the Trustee pursuant to Section 9.01 shall be held in trust and applied by it, in
accordance with the provisions of the Securities and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal of and interest on, and
Conversion Reference Value and Fundamental Change Purchase Price with respect to, the Securities
for whose payment such United States dollars have been deposited with the Trustee.

     Section 9.03. Reinstatement.

     If the Trustee or any Paying Agent is unable to apply any money in accordance with Section
9.02 by reason of any legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, then the
Company’s obligations under this Indenture and the Securities shall be revived and reinstated as
though no deposit had occurred pursuant to Section 9.01 until such time as the Trustee or such
Paying Agent is permitted to apply all such money in accordance with Section 9.02; provided,
however, that if the Company has made any payment of the principal of or interest on, or
Fundamental Change Purchase Price or Conversion Reference Value in respect of, any Securities
because of the reinstatement of its obligations, the Company shall be subrogated to the rights of
the Holders of such Securities to receive any such payment from the money held by the Trustee or
such Paying Agent.

ARTICLE 11

NOTE GUARANTEES

     Section 11.01. Guarantees.

     (a) Each Guarantor hereby jointly and severally, absolutely, unconditionally and irrevocably
guarantees the Securities and obligations of the Company hereunder and thereunder, and guarantees
to

63

 

each Holder of a Security authenticated and delivered by the Trustee, and to the Trustee on
behalf of such Holder, that (i) the principal of and interest on, and Fundamental Change Purchase
Price and Conversion Reference Value with respect to, the Securities will be paid in full when due,
whether at the Final Maturity Date or a Fundamental Change Purchase Date or upon cash conversion of
the Securities, by acceleration or otherwise (including 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 Company 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 Securities 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 Final Maturity Date or a Fundamental Change
Purchase Date or upon a cash conversion of the Securities, by acceleration or otherwise, subject,
however, in the case of clauses (i) and (ii) above, to the limitations set forth in Section 11.03
hereof.

     Each Guarantor hereby agrees that its obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Securities or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder of Securities with
respect to any provisions hereof or thereof, any release of any other Guarantor, the recovery of
any judgment against the Company, 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 Company, any right to require a proceeding first against the Company or any other
Person, protest, notice and all demands whatsoever and covenants that the Guarantee of such
Guarantor shall not be discharged as to Securities 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, or Fundamental
Change Purchase Price or Conversion Reference Value with respect to, such Security, whether at the
Final Maturity Date or a Fundamental Change Purchase Date or upon cash conversion of the
Securities, by acceleration or otherwise, legal proceedings may be instituted by the Trustee on
behalf of, or by, the Holder of such Security, 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 Company 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 Securities, to collect interest on the Securities, or to enforce or exercise
any other right or remedy with respect to the Securities, 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
Company or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in
relation to either the Company 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 11, the maturity of the obligations guaranteed hereby may be accelerated as provided in
Article 7 hereof for the purposes of the Guarantee of such Guarantor, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in

64

 

respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such
obligations as provided in Article 7 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 Company for liquidation or reorganization, should the
Company 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 Company’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 Securities are, pursuant to applicable law, rescinded or
reduced in amount, or must otherwise be restored or returned by any obligee on the Securities,
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 or other duly
authorized representative of such Guarantor on each Security authenticated and delivered to the
Trustee and that this Indenture or a supplemental indenture to this Indenture in substantially the
form of Exhibit C hereto will be executed on behalf of such Guarantor by one of its Officers or
another duly authorized representative. Each Guarantor hereby agrees that its Guarantee will
remain in full force and effect notwithstanding any failure to endorse on each Security a Notation
of Guarantee. The delivery of any Security 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 11.02. 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 11.03. 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
11, result in the obligations of such Guarantor under its Guarantee constituting such fraudulent
transfer or conveyance.

     Section 11.04. 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,

65

 

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 11.05. Subrogation.

     Each Guarantor shall be subrogated to all rights of Holders against the Company in respect of
any amounts paid by any Guarantor pursuant to the provisions of Section 11.01; 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 Company under this Indenture or the Securities shall have been
paid in full.

     Section 11.06. Reinstatement.

     Each Guarantor hereby agrees (and each Person who becomes a Guarantor shall agree) that the
Guarantee provided for in Section 11.01 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 Company upon the bankruptcy or
insolvency of the Company or any Guarantor.

     Section 11.07. Release of a Guarantor.

     Notwithstanding the foregoing, each Guarantee by a Guarantor of the Securities shall be, and
shall provide by its terms that it is automatically and unconditionally released and discharged (i)
upon any sale, exchange, transfer or other disposition (including by way of merger or
consolidation) of the Capital Stock of such Guarantor, following which the Company and its
Subsidiaries cease to own at least a majority of the Voting Stock of such Guarantor, which
transaction is in compliance with the terms of this Indenture, (ii) if such Subsidiary ceases (or
would cease after giving effect to the release of such Guarantee and any concurrent release
pursuant to any other agreement relating to Indebtedness of the Company) to be a guarantor of the
Company’s obligations under the Senior Credit Facility, any other Credit Facility Debt or any
Capital Markets Debt (other than by reason of a payment under a guarantee of any such debt by any
Subsidiary following an occurrence and during the continuance of an event of default under such
debt) or (iii) payment in full of all principal and interest on the Securities.

     Section 11.08. 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.

MISCELLANEOUS

     Section 12.01. Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with any provision of the TIA or
another provision which is required to be included in this Indenture by any of the provisions of
the TIA, the provision or requirement of the TIA shall control. If any provision of this Indenture
modifies or excludes any provision of the TIA that may be so modified or excluded, the latter
provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case
may be.

     Section 12.02. Notices.

     Any demand, authorization notice, request, consent or communication shall be given in writing
and mailed by first-class mail, postage prepaid, or delivered by recognized overnight courier
addressed as follows or transmitted by facsimile transmission (confirmed by delivery in person or

or at any other address previously furnished in writing to the Holders or the Company or any
other obligor on the Securities by the Trustee.

     Such notices or communications shall be effective only when actually received.

     The Company or the Trustee by notice to the other may designate additional or different
addresses for subsequent notices or communications.

     Where this Indenture provides for notice to Holders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, or delivered by recognized overnight courier, to each Holder affected
by such event, at its address as it appears in the register kept by the Primary Registrar, not
later than the latest date, and not earlier than the earliest date, prescribed for the giving of
such notice or by any other manner deemed acceptable to the Trustee. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other
Holders. Any notice when mailed to a Holder in the aforesaid manner shall be conclusively deemed
to have been received by such Holder whether or not actually received by such Holder. Where this
Indenture provides for notice in any manner, such notice may be waived in writing by the Per-

67

 

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

     In case by reason of the suspension of regular mail service or by reason of any other cause,
it shall be impracticable to mail notice of any event as required by any provision of this
Indenture, then any method of giving such notice as shall be reasonably satisfactory to the Trustee
shall be deemed to be a sufficient giving of such notice.

     If the Company mails any notice to a Holder of a Security, it shall mail a copy to the Trustee
and each Registrar and Paying Agent.

     Section 12.03. Disclosure of Names and Addresses of Holders.

     Holders may communicate in accordance with TIA Section 312(b) with other Holders with respect
to their rights under this Indenture or the Securities, and the Trustee shall comply with TIA
Section 312(b). The Company, the Trustee, the Registrar and any other Person shall have the
protection of TIA 312(c). Further, every Holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee or any agent of
either of them shall be held accountable by reason of the disclosure of any information as to the
names and addresses of the Holders in accordance with TIA Section 312, regardless of the source
from which such information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under TIA Section 312.

     Section 12.04. Compliance Certificates and Opinions.

     (a) Upon any application or request by the Company to the Trustee to take any action under any
provision of this Indenture and as may be requested by the Trustee, the Company shall furnish to
the Trustee an Officer’s Certificate stating that all conditions precedent, if any, provided for in
this Indenture relating to the proposed action have been complied with, and an Opinion of Counsel
stating that in the opinion of such counsel all such conditions precedent, if any, have been
complied with, except that, in the case of any such application or request as to which the
furnishing of such certificates or opinions is specifically required by any provision of this
Indenture relating to such particular application or request, no additional certificate or opinion
need be furnished.

     (b) Every certificate or Opinion of Counsel with respect to compliance with a condition or
covenant provided for in this Indenture shall include:

     (1) a statement that the Person signing such certificate or opinion has read and
understands such covenant or condition and the definitions herein relating thereto;

     (2) a brief statement as to the nature and scope of the examination or investigation
upon which the statements or opinions contained in such certificate or opinion are based;

     (3) a statement that, in the opinion of such Person, such Person has made such
examination or investigation as is necessary to enable such Person to express an informed
opinion as to whether or not such covenant or condition has been complied with; and

     (4) a statement as to whether, in the opinion of such Person, such condition or
covenant has been complied with.

68

 

     Section 12.05. Acts of Holders.

     (a) Any request, demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one
or more instruments of substantially similar tenor signed by such Holders in person or by an agent
duly appointed in writing; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the Trustee and, where it is
hereby expressly required, to the Company. Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in
favor of the Trustee and the Company, if made in the manner provided in this Section 12.05.

     (b) The ownership of Securities shall be proved by the register maintained by the Primary
Registrar.

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

     (d) The fact and date of the execution by any Person of any such instrument or writing may be
proved by the affidavit of a witness of such execution or by a certificate of a notary public or
other officer authorized by law to take acknowledgments of deeds, certifying that the individual
signing such instrument or writing acknowledged to him the execution thereof. Where such execution
is by a signer acting in a capacity other than his individual capacity, such certificate or
affidavit shall also constitute sufficient proof of his authority. The fact and date of the
execution of any such instrument or writing, or the authority of the Person executing the same, may
also be proved in any other manner which the Trustee deems sufficient.

     (e) If the Company shall solicit from the Holders any request, demand, authorization,
direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to
a Board Resolution, fix in advance a record date for the determination of such Holders entitled to
give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the
Company shall have no obligation to do so. Any such record date shall be the record date specified
in or pursuant to such Board Resolution, which shall be a date not more than 30 days prior to the
first solicitation of Holders generally in connection therewith and no later than the date such
first solicitation is completed.

     (f) If such a record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act may be given before or after such record date, but only the Holders of
record at the close of business on such record date shall be deemed to be Holders for purposes of
determining whether Holders of the requisite proportion of Securities then Outstanding have
authorized or agreed or consented to such request, demand, authorization, direction, notice,
consent, waiver or other Act, and for this purpose the Securities then Outstanding shall be
computed as of such record date; provided that no such request, demand, authorization, direction,
notice, consent, waiver or other Act by the Holders on such record date shall be deemed effective
unless it shall become effective pursuant to the provisions of this Indenture not later than six
months after such record date.

69

 

     (g) For purposes of this Indenture, any action by the Holders which may be taken in writing
may be taken by electronic means or as otherwise reasonably acceptable to the Trustee.

     Section 12.06. Benefits of Indenture.

     Nothing in this Indenture or in the Securities or the Guarantees, express or implied, shall
give to any Person (other than the parties hereto and their successors hereunder, any Paying Agent
and the Holders) any benefit or any legal or equitable right, remedy or claim under this Indenture.

     Section 12.07. Legal Holidays.

     In any case where any Interest Payment Date, Fundamental Change Purchase Date, Final Maturity
Date or required cash conversion date of any Security shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Securities) payment of interest,
principal or Fundamental Change Purchase Price or the Conversion Reference Value need not be made
on such date, but may be made on the next succeeding Business Day with the same force and effect as
if made on such Interest Payment Date, Fundamental Change Purchase Date, Final Maturity Date or
required cash conversion date, and no interest shall accrue with respect to such payment for the
period from and after such Interest Payment Date, Fundamental Change Purchase Date, Final Maturity
Date or the required cash conversion date, as the case may be, to the next succeeding Business Day.

     Section 12.08. Governing Law; Waiver of Trial by Jury.

     THIS INDENTURE, THE SECURITIES AND THE GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

     EACH PARTY HERETO, AND EACH HOLDER OF A SECURITY BY ITS ACCEPTANCE THEREOF, HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT
OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS
INDENTURE.

     Section 12.09. No Adverse Interpretation of Other Agreements.

     This Indenture may not be used to interpret another indenture, loan or debt agreement of the
Company or a Subsidiary of the Company. Any such indenture, loan or debt agreement may not be used
to interpret this Indenture.

     Section 12.10. No Personal Liability of Directors, Officers, Employees and
Stockholders.

     No director, officer, employee, stockholder, incorporator or agent of the Company or any
Guarantor, as such, will have any liability for any obligations of the Company or such Guarantor
under the Securities, the Guarantees, the Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of the Securities by accepting a
Security waives and releases all such liability.

     Section 12.11. Successors and Assigns.

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

70

 

     Section 12.12. Multiple Counterparts.

     The parties may sign multiple counterparts of this Indenture. Each signed counterpart shall
be deemed an original, but all of them together represent the same agreement.

     Section 12.13. Separability Clause.

     In case any provision in this Indenture or in the Securities or Guarantees 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 12.14. Schedules and Exhibits.

     All schedules and exhibits attached hereto are by this reference made a part hereof with the
same effect as if herein set forth in full.

     Section 12.15. Effect of Headings and Table of Contents.

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

[FORM OF REVERSE SIDE OF SECURITY]

Mylan Inc.

3.75% Cash Convertible Notes Due 2015

     1. Interest

     Mylan Inc., a Pennsylvania corporation (the “Company,” which term shall include any successor
company under the Indenture hereinafter referred to), promises to pay interest on the principal
amount of this Security at the rate of 3.75% per annum. The Company shall pay interest
semiannually on March 15 and September 15 of each year (each, an “Interest Payment Date”),
commencing March 15, 2009. Interest payable on any Interest Payment Date shall include interest
accrued from and including the immediately preceding Interest Payment Date (or if none, from and
including September 15, 2008) to but excluding the relevant Interest Payment Date. Cash interest
will be computed on the basis of a 360-day year comprised of twelve 30-day months. Any payment
required to be made on a day that is not a Business Day shall be made on the next succeeding
Business Day with the same force and effect as if made on such day and without any interest in
respect of the delay. The Company shall, to the fullest extent permitted by law, pay interest in
immediately available funds on overdue principal and interest at the rate of 3.75% per annum,
compounded semiannually, which interest shall accrue from the date such overdue amount was
originally due to the day preceding the date payment of such amount, including interest thereon,
has been made or duly provided for.

     Any reference herein to interest accrued or payable as of any date shall include any Special
Interest or Additional Interest that may be payable in accordance with the provisions of Section
7.02 of the Indenture.

     2. Method of Payment

     The Company shall pay interest on this Security (except defaulted interest) to the Person who
is the Holder of this Security at the close of business on March 1 or September 1, as the case may
be (each, a “Regular Record Date”), next preceding the related Interest Payment Date. The Holder
must surrender this Security to a Paying Agent to collect payment of principal. The Company will
pay principal and interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts.

     3. Paying Agent and Registrar

     Initially, The Bank of New York Mellon (the “Trustee,” which term shall include any successor
trustee under the Indenture hereinafter referred to) will act as Paying Agent and Registrar. The
Company may change any Paying Agent or Registrar without notice to the Holders. The Company or any
of its Affiliates may, subject to certain limitations set forth in the Indenture, act as Paying
Agent.

     4. Indenture

     This Security is one of a duly authorized issue of Securities of the Company designated as its
3.75% Cash Convertible Notes Due 2015 (the “Securities”), issued under an Indenture, dated as of
September 15, 2008 (together with any supplemental indentures thereto, the “Indenture”), among the
Company, the Guarantors named therein and the Trustee. The terms of this Security include those
stated in the Indenture and those required by or made part of the Indenture by reference to the
Trust Indenture Act of

A-3

 

1939, as amended (the “TIA”), as in effect on the date of the Indenture. This Security is subject to all
such terms, and the Holder of this Security is referred to the Indenture and the TIA for a
statement of them. The Securities are limited to $575,000,000 aggregate principal amount. The
Indenture does not limit other debt of the Company, secured or unsecured.

     5. Purchase of Securities at Option of Holder upon a Fundamental Change

     Upon a Fundamental Change, at the option of the Holder and subject to the terms and conditions
of the Indenture, the Company shall become obligated to purchase for cash all or any part specified
by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of
$1,000) of the Securities held by such Holder on the date specified by the Company in accordance
with the provisions of Article 3 of the Indenture. The purchase price of any Securities so
purchased shall equal 100% of the principal amount thereof together with accrued and unpaid
interest, if any, to, but excluding, the Fundamental Change Purchase Date. If the Fundamental
Change Purchase Date falls on a day that is after the Regular Record Date and on or prior to the
Scheduled Trading Day following the corresponding Interest Payment Date, interest, accrued and
unpaid hereon to, but not including, the applicable Fundamental Change Purchase Date, together with
the interest due on the Securities to, but excluding, such Fundamental Change Purchase Date, will
be paid to the Holder in whose name such Security is registered at the close of business on the
Regular Record Date immediately preceding the applicable Fundamental Change Purchase Date.

     6. Cash Conversion

     The Securities are not convertible into shares of Common Stock or any other securities.
Subject to and upon compliance with the provisions of the Indenture and upon the occurrence of the
events specified in the Indenture, the Holder may surrender for cash conversion all or any portion
of this Security that is in an integral multiple of $1,000. Upon cash conversion, the Holder shall
be entitled to receive the consideration specified in the Indenture. The initial Conversion
Reference Rate of the Securities shall be 75.0751 shares of Common Stock per $1,000 principal
amount of Securities, subject to adjustment in accordance with the provisions of Article 4 of the
Indenture. If a Holder cash converts all or any portion of this Security in connection with the
occurrence of certain Fundamental Change transactions, the Conversion Reference Rate shall be
increased in the manner and to the extent described in Section 4.01(i) of the Indenture.

     Securities surrendered for cash conversion (in whole or in part) during the period from the
close of business on any Regular Record Date to the opening of business on the next succeeding
Interest Payment Date shall be accompanied by payment by the Holders of such Securities in funds to
the Paying Agent acceptable to the Company of an amount equal to the interest payable on such
corresponding Interest Payment Date; provided that no such payment need be made: (1) in connection
with a conversion following the Regular Record Date preceding the Final Maturity Date; (2) if the
Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on
or prior to the first Scheduled Trading Day following the corresponding Interest Payment Date; or
(3) to the extent of any overdue interest, if any overdue interest exists at the time of cash
conversion with respect to such Security.

     A Security in respect of which a Holder has submitted a Fundamental Change Purchase Notice may
be cash converted only if such Holder validly withdraws such Fundamental Change Purchase Notice in
accordance with the terms of the Indenture.

A-4

 

     7. Denominations, Transfer, Exchange

     The Securities are in registered form, without coupons, in minimum denominations of $1,000
principal amount and integral multiples of $1,000 principal amount. A Holder may register the
transfer of or exchange Securities in accordance with the Indenture. The Registrar may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes
or other governmental charges that may be imposed in relation thereto by law or permitted by the
Indenture.

     8. Persons Deemed Owners

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

     9. Unclaimed Money

     If money for the payment of principal or interest remains unclaimed for two years, the Trustee
and any Paying Agent will pay the money back to the Company, subject to the provisions of the
Indenture. After that, Holders entitled to money must look to the Company for payment as general
creditors.

     10. Amendment, Supplement and Waiver

     Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented
with the consent of the Holders of at least a majority in aggregate principal amount of the
Securities then outstanding, and an existing Default or Event of Default and its consequence or
compliance with any provision of the Indenture or the Securities may be waived subject to certain
exceptions with the consent of the Holders of a majority in aggregate principal amount of the
Securities then Outstanding. Without the consent of or notice to any Holder, the Company, the
Guarantors and the Trustee may amend or supplement the Indenture or the Securities to, among other
things, (x) cure any ambiguity, omission, mistake, defect or inconsistency or (y) make any other
change that does not adversely affect the interests of the Holders in any material respect.

     11. Successor Entity

     When a successor Person assumes all the obligations of its predecessor under the Securities
and the Indenture in accordance with the terms and conditions of the Indenture, the predecessor
Person (except in certain circumstances specified in the Indenture) shall be released from those
obligations.

     12. Defaults and Remedies

     An Event of Default shall occur upon the occurrence of any of the events specified in Section
7.01(a) of the Indenture. Subject to the provisions of Section 7.02(c) of the Indenture, if an
Event of Default shall occur and be continuing with respect to the Securities (other than an Event
of Default specified in clause (9) or (10) of Section 7.01(a) of the Indenture with respect to the
Company), the Trustee or the Holders of not less than 25% in aggregate principal amount of the
Securities then Outstanding may, and the Trustee at the request of such Holders shall, declare all
unpaid principal of and accrued interest on all Securities to be due and payable, by a notice in
writing to the Company (and to the Trustee if given by the Holders of the Securities). Upon any
such declaration, such principal and interest shall become due and payable immediately. If an
Event of Default specified in clauses (9) or (10) of Section 7.01(a) of the Indenture occurs and is
continuing with respect to the Company, then all the Securities shall ipso facto become and be due
and payable immediately in an amount equal to the principal amount of the Securities,

A-5

 

together with accrued and unpaid interest, if any, to the date the Securities become due and payable, without any
declaration or other act on the part of the Trustee or any Holder.

     The Holders of a majority in aggregate principal amount of the Securities Outstanding, by
written notice to the Company and the Trustee, may rescind and annul an acceleration and its
consequences if: (a) the Company has paid or deposited with the Trustee a sum sufficient to pay (1)
all sums paid or advanced by the Trustee under the Indenture and the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, (2) all overdue interest on all Outstanding
Securities, (3) the principal of any Outstanding Securities which have become due otherwise than by
such declaration of acceleration and interest thereon at the rate borne by the Securities, and (4)
to the extent that payment of such interest is lawful, interest upon overdue interest at the rate
borne by the Securities; (b) the rescission would not conflict with any judgment or decree of a
court of competent jurisdiction; and (c) all Defaults and Events of Default, other than the
nonpayment of principal of and interest on the Securities which have become due solely by such
declaration of acceleration, have been cured or waived. No such rescission shall affect any
subsequent Default or impair any right consequent thereon.

     Holders may not enforce the Indenture or the Securities except as provided in the Indenture.
The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the
Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of
the Securities then outstanding may direct the Trustee in its exercise of any trust or power. The
Trustee may, in accordance with the provisions of the Indenture, withhold from Holders notice of
any continuing Default (except a Default in payment of principal or interest or to deliver amounts
owing upon conversion) if and so long as it determines that withholding notice is in their
interests. The Company is required to file periodic certificates with the Trustee as to the
Company’s compliance with the Indenture and knowledge or status of any Default.

     13. Trustee Dealings with the Company

     The Bank of New York Mellon, the initial Trustee under the Indenture, or any of its
Affiliates, in its individual or any other capacity, may make loans to, accept deposits from and
perform services for the Company or an Affiliate of the Company, and may otherwise deal with the
Company or an Affiliate of the Company, as if it were not the Trustee.

     14. No Recourse Against Others

     No director, officer, employee, stockholder, incorporator or agent of the Company, as such,
will have any liability for any obligations of the Company under the Securities, the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or their creation. Each
Holder of the Securities by accepting a Security waives and releases all such liability.

     15. Authentication

     This Security shall not be valid until the Trustee or an authenticating agent manually signs
the certificate of authentication on the other side of this Security.

     16. Abbreviations and Definitions

     Customary abbreviations may be used in the name of the Holder or an assignee, such as: TEN COM
(= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right

A-6

 

of survivorship and not as tenants in common), CUST (= Custodian) and UGMA (= Uniform Gifts to Minors
Act).

Holders. 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

Re: Restricted Securities Legend Removal

Restricted CUSIP:                    

Dear Sir/Madam:

     Whereas the 3.75% Cash Convertible Notes due 2015 (the “Securities”) of Mylan Inc. (the
“Company”) have become freely tradable without restriction under the U.S. securities laws by
non-affiliates of the Company pursuant to Rule 144 under the Securities Act of 1933, as amended, in
accordance with Section 2.18 of the indenture (the “Indenture”) dated as of September 15, 2008
between the Company, the Bank of New York Mellon, as Trustee (the “Trustee”), and the guarantors
party thereto pursuant to which the Securities were issued, the Company hereby instructs you that:

	 	(i)	 	the restrictive securities legend described in Section 2.07(g) of the Indenture and set
forth on the Securities shall be deemed removed from the Global Securities (as defined in
