    EXHIBIT 10.1

     SEVERANCE COMPENSATION AGREEMENT dated as of July 9, 2007, between O’Charley’s Inc., a
Tennessee corporation (the “Company”), and John R. Grady (the “Executive”).

     The Company’s Board of Directors has determined that it is appropriate to reinforce and
encourage the continued attention and dedication of certain members of the Company’s senior
management, including the Executive, to their assigned duties without distraction in potentially
disturbing circumstances arising from the possibility of a change in control of the Company.

     This Agreement sets forth the severance compensation which the Company agrees it will pay to
the Executive if the Executive’s employment with the Company terminates under one of the
circumstances described herein following a Change In Control of the Company (as defined herein).

     1. Term. This Agreement shall become effective upon the commencement of Executive’s
employment with the Company. This Agreement shall terminate, except to the extent that any
obligation of the Company hereunder remains unpaid as of such time, upon the earliest of (i) one
year from the date hereof if a Change in Control of the Company has not occurred prior to such
date; (ii) the termination of the Executive’s employment with the Company based on death,
Disability (as defined in Section 3(b)), Retirement (as defined in Section 3(c)) or Cause (as
defined in Section 3(d)) or by the Executive other than for Good Reason (as defined in Section
3(e)); and (iii) eighteen months from the date of a Change in Control of the Company.

     2. Change in Control. No compensation shall be payable under this Agreement unless and until
(a) there shall have been a Change in Control of the Company while the Executive is still an
employee of the Company and (b) the Executive’s employment by the Company thereafter shall have
been terminated in accordance with Section 3. For purposes of this Agreement, a Change in Control
means the happening of any of the following:

     (i) any person or entity, including a “group” as defined in Section 13(d)(3) of the
Securities Exchange Act of 1934, other than the Company, a wholly-owned subsidiary thereof,
any employee benefit plan of the Company or any of its Subsidiaries becomes the beneficial
owner of the Company’s securities having 30% or more of the combined voting power of the
then outstanding securities of the Company that may be cast for the election of directors of
the Company (other than as a result of an issuance of securities initiated by the Company in
the ordinary course of business); or

     (ii) as the result of, or in connection with, any cash tender or exchange offer, merger
or other business combination, sale of assets or contested election, or any combination of
the foregoing transactions, less than a majority of the combined voting power of the then
outstanding securities of the Company or any successor corporation or entity entitled to
vote generally in the election of the directors of the Company or such other corporation or
entity after such transaction are held in the aggregate by the holders

 

 

of the Company’s securities entitled to vote generally in the election of directors of
the Company immediately prior to such transaction; or

     (iii) during any period of two consecutive years, individuals who at the beginning of
any such period constitute the Board cease for any reason to constitute at least a majority
thereof, unless the election, or the nomination for election by the Company’s shareholders,
of each director of the Company first elected during such period was approved by a vote of
at least two-thirds of the directors of the Company then still in office who were directors
of the Company at the beginning of any such period.

     3. Termination Following Change in Control. (a) If a Change in Control of the Company shall
have occurred while the Executive is still an employee of the Company, the Executive shall be
entitled to the compensation provided in Section 4 upon the subsequent termination of the
Executive’s employment with the Company by the Executive or by the Company within eighteen months
of the Change in Control of the Company unless such termination is as a result of (i) the
Executive’s death; (ii) the Executive’s Disability (as defined in Section (3)(b) below); (iii) the
Executive’s Retirement (as defined in Section 3(c) below); (iv) the Executive’s termination by the
Company for Cause (as defined in Section 3(d) below); or (v) the Executive’s decision to terminate
employment other than for Good Reason (as defined in Section 3(e) below).

          (b) Disability. If, as a result of the Executive’s incapacity due to physical or mental
illness, the Executive shall have been absent from his duties with the Company on a full-time basis
for six months and within 30 days after written notice of termination is thereafter given by the
Company the Executive shall not have returned to the full-time performance of the Executive’s
duties, the Company may terminate this Agreement for “Disability.”

          (c) Retirement. The term “Retirement” as used in this Agreement shall mean termination by the
Company or the Executive of the Executive’s employment based on the Executive’s having reached age
65 or such other age as shall have been fixed in any arrangement established with the Executive’s
consent with respect to the Executive.

          (d) Cause. The Company may terminate the Executive’s employment for Cause. For purposes of
this Agreement only, the Company shall have “Cause” to terminate the Executive’s employment
hereunder only on the basis of fraud, misappropriation or embezzlement on the part of the
Executive. Notwithstanding the foregoing, the Executive shall not be deemed to have been
terminated for Cause unless and until there shall have been delivered to the Executive a copy of a
resolution duly adopted by the affirmative vote of not less than three-quarters of the membership
of the Company’s Board of Directors (excluding the Executive if the Executive is then a member of
the Board of Directors) at a meeting of the Board called and held for the purpose (after reasonable
notice to the Executive and an opportunity for the Executive, together with the Executive’s
counsel, to be heard before the Board), finding that in the good faith opinion of the Board the
Executive was guilty of conduct set forth in the second sentence of this Section 3(d) and
specifying the particulars thereof in detail.

2

 

          (e) Good Reason. The Executive may terminate the Executive’s employment for Good Reason at
any time during the term of this Agreement. For purposes of this Agreement “Good Reason” shall
mean any of the following (without the Executive’s express written consent):

     (i) the assignment to the Executive by the Company of duties inconsistent with the
Executive’s position, duties, responsibilities and status with the Company immediately prior
to a Change in Control of the Company, or a change in the Executive’s titles or offices as
in effect immediately prior to a Change in Control of the Company, or any removal of the
Executive from or any failure to reelect the Executive to any of such positions, except in
connection with the termination of his employment for Disability, Retirement or Cause or as
a result of the Executive’s death or by the Executive other than for Good Reason;

     (ii) a reduction by the Company in the Executive’s base salary as in effect on the date
hereof or as the same may be increased from time to time during the term of this Agreement;

     (iii) a relocation of the Company’s principal executive offices to a location outside
of Nashville, Tennessee, or the Executive’s relocation to any place other than the location
at which the Executive performed the Executive’s duties prior to a Change in Control of the
Company, except for required travel by the Executive on the Company’s business to an extent
substantially consistent with the Executive’s business travel obligations at the time of a
Change in Control of the Company;

     (iv) any material breach by the Company of any provision of this Agreement;

     (v) any failure by the Company to obtain the assumption of this Agreement by any
successor or assign of the Company; or

     (vi) any purported termination of the Executive’s employment by the Company which is
not effected pursuant to a Notice of Termination satisfying the requirements of Section
3(f), and for purposes of this Agreement, no such purported termination shall be effective.

          (f) Notice of Termination. Any termination by the Company pursuant to Section 3(b), 3(c) or
3(d) or by the Executive pursuant to Section 3(e) shall be communicated by a Notice of Termination.
For purposes of this Agreement, a “Notice of Termination” shall mean a written notice which
indicates those specific termination provisions in this Agreement relied upon and which sets forth
in reasonable detail the facts and circumstances claimed to provide a basis for termination of the
Executive’s employment under the provisions so indicated. For purposes of this Agreement, no such
purported termination by the Company or by the Executive shall be effective without such Notice of
Termination.

          (g) Date of Termination. “Date of Termination” shall mean (a) if this Agreement is terminated
by the Company for Disability, 30 days after Notice of Termination is given to the Executive
(provided that the Executive shall not have returned to the performance of

3

 

the Executive’s duties on a full-time basis during such 30-day period), (b) if the Executive’s
employment is terminated by the Company for any other reason, the date on which a Notice of
Termination is given, or (c) if the Executive terminates his employment pursuant to Section 3(e),
the date on which a Notice of Termination is given.

     4. Severance Compensation upon Termination of Employment. (a) If the Company shall terminate
the Executive’s employment within eighteen months following a Change in Control other than pursuant
to Section 3(b), 3(c) or 3(d) or if the Executive shall terminate his employment within eighteen
months following a Change in Control for Good Reason, then the Company shall pay to the Executive
as severance pay in a lump sum, in cash, on the fifth day following the Date of Termination, an
amount equal to the sum of (i) 150% of the average of the aggregate annual base salary paid to the
Executive by the Company during the three calendar years preceding the Change in Control of the
Company and (ii) 150% of the highest bonus compensation paid to the Executive for any of the three
calendar years preceding the Change in Control of the Company; provided, however, that if the lump
sum severance payment under this Section 4, either alone or together with other payments which the
Executive has the right to receive from the Company, would constitute a “parachute payment” (as
defined in Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”)), such lump
sum severance payment shall be reduced to the largest amount as will result in no portion of the
lump sum severance payment under this Section 4 being subject to the excise tax imposed by Section
4999 of the Code. For avoidance of doubt, for purposes of subsection (ii) of the preceding
sentence, the bonus compensation total shall not include any payments made by the Company to
Executive pursuant to the Company’s agreement with the former owners of Ninety Nine Restaurant &
Pub to pay a total of $1.0 million per year, plus accrued interest, through 2007 to certain key
employees of Ninety Nine who continue to be employed with the Company.

          (b) In addition to the lump sum payment provided in Section 4(a), if the Company shall
terminate the Executive’s employment within eighteen months following a Change in Control other
than pursuant to Section 3(b), 3(c) or 3(d) or if the Executive shall terminate his employment
within eighteen months following a Change in Control for Good Reason, then the Company shall
provide to the Executive health insurance equivalent to that provided to the Executive immediately
prior to termination until the earlier of: (i) eighteen months following the Date of Termination or
(ii) such time as Executive is employed by another employer and is covered or permitted to be
covered by benefit plans of another employer providing substantially similar coverage.

     5. No Obligation To Mitigate Damages; No Effect on Other Contractual Rights. (a) The
Executive shall not be required to mitigate damages or the amount of any payment provided for under
this Agreement by seeking other employment or otherwise, nor shall the amount of any payment
provided for under this Agreement be reduced by any compensation earned by the Executive as the
result of employment by another employer after the Date of Termination, or otherwise.

          (b) The provisions of this Agreement, and any payment provided for hereunder, shall not reduce
any amounts otherwise payable, or in any way diminish the Executive’s existing rights, or rights
which would accrue solely as a result of the passage of time,

4

 

under any benefit plan, incentive plan or stock option plan, employment agreement or other
contract, plan or arrangement.

     6. Successor to the Company. (a) The Company will require any successor or assign (whether
direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of
the business and/or assets of the Company, by agreement in form and substance satisfactory to the
Executive, expressly, absolutely and unconditionally to assume and agree to perform this Agreement
in the same manner and to the same extent that the Company would be required to perform it if no
such succession or assignment had taken place. Any failure of the Company to obtain such agreement
prior to the effectiveness of any such succession or assignment shall be a material breach of this
Agreement and shall entitle the Executive to terminate the Executive’s employment for Good Reason.
As used in this Agreement, “Company” shall mean the Company as hereinbefore defined and any
successor or assign to its business and/or assets as aforesaid which executes and delivers the
agreement provided for in this Section 6 or which otherwise becomes bound by all the terms and
provisions of this Agreement by operation of law. If at any time during the term of this Agreement
the Executive is employed by any corporation, a majority of the voting securities of which is then
owned by the Company, “Company” as used in Sections 3, 4, 11 and 12 hereof shall in addition
include such employer. In such event, the Company agrees that it shall pay or shall cause such
employer to pay any amounts owed to the Executive pursuant to Section 4 hereof.

          (b) This Agreement shall inure to the benefit of and be enforceable by the Executive’s
personal and legal representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees. If the Executive should die while any amounts are still payable to him
hereunder, all such amounts, unless otherwise provided herein, shall be paid in accordance with the
terms of this Agreement to the Executive’s devisee, legatee, or other designee or, if there be no
such designee, to the Executive’s estate.

     7. Notice. For purposes of this Agreement, notices and all other communications provided for
in the Agreement shall be in writing and shall be deemed to have been duly given when delivered or
mailed by United States registered mail, return receipt requested, postage prepaid, as follows:

or such other address as either party may have furnished to the other in writing in accordance
herewith, except that notices of change of address shall be effective only upon receipt.

     8. Miscellaneous. No provisions of this Agreement may be modified, waived or discharged
unless such waiver, modification or discharge is agreed to in a writing signed by the Executive and
the Company. No waiver by either party hereto at any time of any breach by the other party hereto
of, or compliance with, any condition or provision of this Agreement to be performed by such other
party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at
any prior or subsequent time. No agreements or representations, oral or otherwise, express or
implied, with respect to the subject matter hereof have been made by either party which are not set
forth expressly in this Agreement. This Agreement shall be governed by and construed in accordance
with the laws of the State of Tennessee.

     9. Validity. The invalidity or unenforceability of any provisions of this Agreement shall not
affect the validity or enforceability of any other provision of this Agreement, which shall remain
in full force and effect.

     10. Counterparts. This Agreement may be executed in one or more counterparts, each of which
shall be deemed to be an original but all of which together will constitute one and the same
instrument.

     11. Legal Fees and Expenses. In the event either party hereto shall institute litigation
against the other party hereto relating to the interpretation or enforcement of this Agreement, the
prevailing party in such litigation shall be entitled to recover from the other party any and all
attorneys’ and related fees and expenses incurred by the prevailing party in such litigation.

     12. Confidentiality. The Executive shall retain in confidence any and all confidential
information known to the Executive concerning the Company and its business so long as such
information is not otherwise publicly disclosed. The provisions of this Section 12 are not
intended to restrict the ability of the Executive following termination of employment for any
reason to engage in any business which is, directly or indirectly, competitive with the business
conducted by the Company.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first above
written.

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

     Any of the Notes may have such letters, numbers or other marks of identification and such
notations, legends, endorsements or changes as the officers executing the same may approve
(execution thereof to be conclusive evidence of

8

 

such approval) and as are not inconsistent with the
provisions of this Indenture, or as may be required by the Custodian, the Depositary or by the
National Association of Securities Dealers, Inc. or as may be required to comply with any
applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation
of any securities exchange or automated quotation system on which the Notes may be listed, or to
conform to usage, or to indicate any special limitations or restrictions to which any particular
Notes are subject.

     So long as the Notes are eligible for book-entry settlement with the Depositary, or unless
otherwise required by law, or otherwise contemplated by Section 2.05(a), all of the Notes will be
represented by one or more Notes in global form registered in the name of the Depositary or the

owners of a Global Note shall not be entitled to have certificates registered in their names, will
not receive or be entitled to receive physical delivery of certificates in definitive form and will
not be considered holders of such Global Note.

     Any Global Note shall represent such of the outstanding Notes as shall be specified therein
and shall provide that it shall represent the aggregate amount of outstanding Notes from time to
time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may
from time to time be increased or reduced to reflect redemptions, conversions, transfers or
exchanges permitted hereby. Any endorsement of a Global Note to reflect the amount of any increase

interest from the date specified on the face of the form of Note attached as Exhibit A hereto.
Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve
30-day months.

     The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register
at the close of business on any record date with respect to any interest payment date shall be
entitled to receive the interest payable on such interest payment date, except that the interest
payable upon redemption upon the occurrence of a Designated Event will be payable to the Person to
whom principal

9

 

is payable pursuant to such redemption. Interest shall be payable at the office of
the Company maintained by the Company for such purposes in the Borough of Manhattan, City of New
York, which shall initially be an office or agency of the Trustee. The Company shall pay interest
(i) on any Notes in certificated form by check mailed to the address of the Person entitled thereto
as it appears in the Note Register (or upon written notice by such Person, by wire transfer in
immediately available funds, if such Person is entitled to interest on aggregate principal in
excess of $2 million) or (ii) on any Global Note by wire transfer of immediately available funds to
the account of the Depositary or its nominee. The term “record date” with respect to any interest
payment date shall mean the February 15 or August 15 preceding the applicable March 1 or September
1 interest payment date, respectively.

     Any interest on any Note which is payable, but is not punctually paid or duly provided for, on
any March 1 or September 1 (herein called “Defaulted Interest”) shall forthwith cease to be payable
to the Noteholder on the relevant record date by virtue of his having been such Noteholder, and
such Defaulted Interest shall be paid by the Company, at its election in each case, as provided in
clause (1) or (2) below:

     (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose
names the Notes (or their respective Predecessor Notes) are registered at the close of business 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 Note and the date of the proposed payment (which shall be not
less than twenty-five (25) days after the receipt by the Trustee of such notice, unless the Trustee
shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee
an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Interest
or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of
the proposed payment, such money when deposited to be held in trust for the benefit of the Persons
entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a
special record date for the payment of such Defaulted Interest which shall be not more than fifteen
(15) days and not less than ten (10) days prior to the date of the proposed payment, and not less
than ten (10) days after the receipt by the Trustee of the notice of the proposed payment.
The Trustee shall promptly notify the Company of such special record date and, in the name and
at the expense of the Company, 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 his address as it appears in the Note Register, not less than ten (10) days prior to such
special record date. Notice of the proposed payment of such Defaulted Interest and the special
record date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in
whose names the Notes (or their respective Predecessor Notes) are

10

 

registered at the close of
business on such special record date and shall no longer be payable pursuant to the following
clause (2) of this Section 2.03.

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

     Section 2.04. Execution of Notes. The Notes shall be signed in the name and on behalf of the
Company by the manual or facsimile signature of its Chairman of the Board, Chief Executive Officer,
President or any Vice President (whether or not designated by a number or numbers or word or words
added before or after the title “Vice President”) and attested by the manual or facsimile signature
of its Secretary or any of its Assistant Secretaries or its Treasurer or any of its Assistant
Treasurers (which may be printed, engraved or otherwise reproduced thereon, by facsimile or
otherwise). Only such Notes as shall bear thereon a certificate of authentication substantially in
the form set forth on the form of Note attached as Exhibit A hereto, manually executed by the
Trustee (or an authenticating agent appointed by the Trustee as provided by Section 17.11), shall
be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such
certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company
shall be conclusive evidence that the Note so authenticated has been duly authenticated and
delivered hereunder and that the holder is entitled to the benefits of this Indenture.

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

     Section 2.05. Exchange and Registration of Transfer of Notes . (a) The Company shall cause
to be kept at the Corporate Trust Office a register (the register maintained in such office and in
any other office or agency of the Company designated pursuant to Section 6.02 being herein
sometimes collectively referred to as the “Note Register”) in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration of Notes and of
transfers of Notes. The Note Register shall be in

11

 

written form or in any form capable of being
converted into written form within a reasonably prompt period of time. The Trustee is hereby
appointed “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein
provided. The Company may appoint one or more co-registrars in accordance with Section 6.02.

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

     Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate
principal amount, upon surrender of the Notes to be exchanged at any such office or agency
maintained by the Company pursuant to Section 6.02. Whenever any Notes are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes
which the Noteholder making the exchange is entitled to receive bearing registration numbers not
contemporaneously outstanding.

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

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

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

     Neither the Company nor the Trustee nor any Note Registrar shall be required to exchange or
register a transfer of (a) any Notes or portions thereof surrendered for conversion pursuant to
Article 16 or (b) any Notes or portions thereof tendered for redemption (and not withdrawn)
pursuant to Section 3.05.

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

12

 

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

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

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

     (iv) In the event of the occurrence of any of the events specified in clause (ii)
above, the Company will promptly make available to the

13

 

Trustee a reasonable supply of
certificated Notes in definitive, fully registered form, without interest coupons.

     (v) Neither any members of, or participants in, the Depositary (“Agent Members”) nor
any other Persons on whose behalf Agent Members may act shall have any rights under this
Indenture with respect to any Global Note registered in the name of the Depositary or any
nominee thereof, and the Depositary or such nominee, as the case may be, may be treated by
the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner
and holder of such Global Note for all purposes whatsoever. Notwithstanding the
foregoing, nothing herein shall prevent the 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 Note.

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

     (c) Reserved.

     (d) Reserved.

     (e) Reserved.

     (f) The Trustee shall have no responsibility or obligation to any Agent Members or any other
Person with respect to the accuracy of the books or records, or the acts or omissions, of the
Depository or its nominee or of any participant or member thereof, with respect to any ownership
interest in the Notes or with respect to the delivery to any Agent Member or other Person (other
than the Depositary) of any notice (including any notice of redemption) or the payment of any
amount, under or with respect to such Notes. All notices and

14

 

communications to be given to the
Noteholder and all payments to be made to Noteholders under the Notes shall be given or made only
to or upon the order of the registered Noteholders (which shall be the Depository or its nominee in
the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised
only through the Depository subject to the customary procedures of the Depository. The Trustee may
rely and shall be fully protected in relying upon information furnished by the Depository with
respect to its Agent Members.

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

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

     Following receipt by the Trustee or such authenticating agent, as the case may be, of
satisfactory security or indemnity and evidence, as described in the preceding paragraph, the
Trustee or such authenticating agent may authenticate any such substituted Note and make available
for delivery such Note. Upon the issuance of any substituted Note, the Company may require the
payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge
that may be imposed in relation thereto and any other expenses connected therewith. In case any
Note which has matured or is about to mature or has been tendered for redemption upon a Designated
Event (and not withdrawn) or is to be converted into Common Stock shall become mutilated or be
destroyed, lost or stolen, the Company may, instead of issuing a substitute Note, pay or authorize
the payment of or convert or authorize the conversion of the same (without

15

 

surrender thereof except
in the case of a mutilated Note), as the case may be, if the applicant for such payment or
conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating
agent such security or indemnity as may be required by them to save each of them harmless for any
loss, liability, cost or expense caused by or in connection with such substitution, and, in every
case of destruction, loss or theft, the applicant shall also furnish to the Company, the Trustee
and, if applicable, any paying agent or conversion agent evidence to their satisfaction of the
destruction, loss or theft of such Note and of the ownership thereof.

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

     Section 2.07. Temporary Notes. Pending the preparation of Notes in certificated form, the
Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon
the written request of the Company, authenticate and deliver temporary Notes (printed or
lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially
in the form of the Notes in
certificated form, but with such omissions, insertions and variations as may be appropriate
for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be
executed by the Company and authenticated by the Trustee or such authenticating agent upon the same
conditions and in substantially the same manner, and with the same effect, as the Notes in
certificated form. Without unreasonable delay, the Company will execute and deliver to the Trustee
or such authenticating agent Notes in certificated form and thereupon any or all temporary Notes
may be surrendered in exchange therefor, at each office or agency maintained by the Company
pursuant to Section 6.02 and the Trustee or such authenticating agent shall authenticate and make
available for delivery in exchange for such temporary Notes an equal aggregate principal amount of
Notes in certificated form. Such exchange shall be made by the Company at its own expense and
without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be
entitled to the same benefits and subject to the same limitations under this Indenture as Notes in
certificated form authenticated and delivered hereunder.

16

 

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

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

     Section 3.03. Reserved.

     Section 3.04. Reserved.

     Section 3.05. Redemption At Option of Holders Upon a Designated Event.

     (a) If there shall occur a Designated Event at any time prior to maturity of the Notes, then
each Noteholder shall have the right, at such holder’s option, to require the Company to redeem for
cash all of such holder’s Notes, or any portion thereof that is a multiple of $1,000 principal
amount, on the date (the “Designated Event Redemption Date”) that is thirty (30) days after the
date of the Designated Event Notice (as defined in Section 3.05(b)) of such Designated Event (or,
if such 30th day is not a Business Day, the next succeeding Business Day) at a redemption price
equal to 100% of the principal amount thereof, together with accrued interest to, but excluding,
the Designated Event

17

 

Redemption Date. Such redemption pursuant to this Section 3.05 shall be made
at the option of the Noteholder, upon:

     (i) delivery to the Trustee (or other paying agent appointed by the Company) by a
Noteholder of a duly completed form entitled “Option to Elect Repayment Upon A Designated
Event” (the “Redemption Notice”) in the form set forth on the reverse of the Note during
the period beginning at any time from the opening of business on the date the Designated
Event Notice is mailed until the close of business on the Designated Event Redemption
Date; and

     (ii) delivery or book-entry transfer of the Note or Notes to the Trustee (or other
paying agent appointed by the Company) at any time after delivery of the Designated Event
Notice (together with all necessary endorsements) at the Corporate Trust Office of the
Trustee (or other paying agent appointed by the Company) in the Borough of Manhattan as
provided in Section 6.02, such delivery being a condition to receipt by the holder of the
redemption price therefor; provided that such redemption price shall be so paid pursuant
to this Section 3.05 only if the Note so delivered to the Trustee (or other paying agent
appointed by the Company)
shall conform in all respects to the description thereof in the related Redemption
Notice.

     The Company shall redeem, pursuant to this Section 3.05, a portion of a Note, if the principal
amount of such portion is $1,000 or a whole multiple of $1,000. Provisions of this Indenture that
apply to the redemption of all of a Note also apply to the redemption of such portion of such Note.
Upon presentation of any Note redeemed in part only, the Company shall execute and, upon the
Company’s written direction to the Trustee, the Trustee shall authenticate and make available for
delivery to the holder thereof, at the expense of the Company, a new Note or Notes, of authorized
denominations, in aggregate principal amount equal to the unredeemed portion of the Notes
presented.

     Notwithstanding anything herein to the contrary, any holder delivering to the Trustee (or
other paying agent appointed by the Company) the Redemption Notice contemplated by this Section
3.05 shall have the right to withdraw such Redemption Notice at any time prior to the close of
business on the Designated Event Redemption Date by delivery of a written notice of withdrawal to
the Trustee (or other paying agent appointed by the Company) in accordance with Section 3.06.

     The Trustee (or other paying agent appointed by the Company) shall promptly notify the Company
of the receipt by it of any Redemption Notice or written notice of withdrawal thereof.

18

 

     (b) On or before the tenth day after the occurrence of a Designated Event, the Company or, at
its written request (which must be received by the Trustee at least five (5) Business Days prior to
the date the Trustee is requested to give notice as described below, unless the Trustee shall agree
in writing to a shorter period), the Trustee, in the name of and at the expense of the Company,
shall mail or cause to be mailed to all holders of record on the date of the Designated Event a
notice (the “Designated Event Notice”) of the occurrence of such Designated Event and of the
redemption right at the option of the holders arising as a result thereof. Such notice shall be
mailed by first class mail. The notice, if mailed in the manner herein provided, shall be
conclusively presumed to have been duly given, whether or not the holder receives such notice. If
the Company shall give such notice, the Company shall also deliver a copy of the Designated Event
Notice to the Trustee at such time as it is mailed to Noteholders. Concurrently with the mailing
of any Designated Event Notice, the Company shall issue a press release announcing such Designated
Event referred to in the Designated Event Notice, the form and content of which press release shall
be determined by the Company in its sole discretion. The failure to issue any such press release
or any defect therein shall not affect the validity of the Designated Event Notice or any
proceedings for the redemption of any Note
which any Noteholder may elect to have the Company redeem as provided in this Section 3.05.

     Each Designated Event Notice shall specify the circumstances constituting the Designated
Event, the Designated Event Redemption Date, the price at which the Company shall be obligated to
redeem Notes, that the holder must exercise the redemption right on or prior to the close of
business on the Designated Event Redemption Date (the “Designated Event Expiration Time”), that the
holder shall have the right to withdraw any Notes surrendered prior to the Designated Event
Expiration Time, a description of the procedure which a Noteholder must follow to exercise such
redemption right and to withdraw any surrendered Notes, the place or places where the holder is to
surrender such holder’s Notes, the amount of interest accrued on each Note to the Designated Event
Redemption Date and the CUSIP number or numbers of the Notes (if then generally in use).

     No failure of the Company to give the foregoing notices and no defect therein shall limit the
Noteholders’ redemption rights or affect the validity of the proceedings for the redemption of the
Notes pursuant to this Section 3.05.

     (c) In the case of a reclassification, change, consolidation, merger, combination, sale or
conveyance to which Section 16.06 applies, in which the Common Stock of the Company is changed or
exchanged as a result into the right to receive stock, securities or other property or assets
(including cash), which includes shares of Common Stock of the Company or shares of common stock of
another Person that are, or upon issuance will be, traded on a United States national securities
exchange or approved for trading on an established automated

19

 

over-the-counter trading market in the
United States and such shares constitute at the time such change or exchange becomes effective in
excess of 50% of the aggregate fair market value of such stock, securities or other property or
assets (including cash) (as determined by the Company, which determination shall be conclusive and
binding), then the Person formed by such consolidation or resulting from such merger or which
acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental
indenture (accompanied by an Opinion of Counsel that such supplemental indenture complies with this
Indenture and the Trust Indenture Act as in force at the date of execution of such supplemental
indenture) modifying the provisions of this Indenture relating to the right of holders of the Notes
to cause the Company to redeem the Notes following a Designated Event, including without limitation
the applicable provisions of this Section 3.05 and the definitions of Common Stock and Designated
Event, as appropriate, as determined in good faith by the Company (which determination shall be
conclusive and binding), to make such provisions apply to such other Person if different from the
Company and the common stock issued by such Person (in lieu of the Company and the Common Stock of
the Company).

     (d) The Company will comply with the provisions of Rule 13e-4 and any other tender offer rules
under the Exchange Act to the extent then applicable in connection with the redemption rights of
the holders of Notes in the event of a Designated Event.

     Section 3.06. Effect of Redemption Notice.

     (a) Upon receipt by the Trustee (or other paying agent appointed by the Company) of the
Redemption Notice specified in Section 3.05(a), the holder of the Note in respect of which such
Redemption Notice was given shall (unless such Redemption Notice is validly withdrawn) thereafter
be entitled to receive solely the redemption price with respect to such Note. Such redemption
price shall be paid to such Noteholder, subject to receipt of funds and/or Notes by the Trustee (or
other paying agent appointed by the Company), promptly following the later of (x) the Designated
Event Redemption Date with respect to such Note (provided the holder has satisfied the conditions
in Section 3.05) and (y) the time of delivery of such Note to the Trustee (or other paying agent
appointed by the Company) by the holder thereof in the manner required by Section 3.05. Notes in
respect of which a Redemption Notice has been given by the holder thereof may not be converted
pursuant to Article 16 hereof on or after the date of the delivery of such Redemption Notice unless
such Redemption Notice has first been validly withdrawn.

     (b) A Redemption Notice may be withdrawn by means of a written notice of withdrawal delivered
to the office of the Trustee (or other paying agent appointed by the Company) in accordance with
the Redemption Notice at any

20

 

time prior to the close of business on the Designated Event Redemption
Date, specifying:

     (i) the certificate number, if any, of the Note in respect of which such notice of
withdrawal is being submitted, or the appropriate Depositary information if the Note in
respect of which such notice of withdrawal is being submitted is represented by a Global
Note,

     (ii) the principal amount of the Note with respect to which such notice of withdrawal
is being submitted, and

     (iii) the principal amount, if any, of such Note which remains subject to the
original Redemption Notice and which has been or will be delivered for redemption by the
Company.

     Section 3.07. Deposit of Redemption Price. (a) Prior to 10:00 a.m. (New York City Time) on
the Business Day following the Designated Event Redemption Date, the Company shall deposit with the
Trustee (or other paying
agent appointed by the Company; or, if the Company or a Subsidiary or an Affiliate of either
of them is acting as the paying agent, shall segregate and hold in trust as provided in Section
6.04) an amount of cash (in immediately available funds if deposited on such Business Day),
sufficient to pay the aggregate redemption price of all the Notes or portions thereof that are to
be redeemed as of the Designated Event Redemption Date.

     (b) If the Trustee or other paying agent appointed by the Company, or the Company or a
Subsidiary or Affiliate of either of them, if such entity is acting as the paying agent, holds cash
sufficient to pay the aggregate redemption price of all the Notes, or portions thereof, that are to
be redeemed as of the Designated Event Redemption Date, on or after the Designated Event Redemption
Date (i) the Notes will cease to be outstanding, (ii) interest on the Notes will cease to accrue,
and (iii) all other rights of the holders of such Notes will terminate, whether or not book-entry
transfer of the Notes has been made or the Notes have been delivered to the Trustee or paying
agent, other than the right to receive the redemption price upon delivery of the Notes.

     Section 3.08. Repayment to the Company. The Trustee (or other paying agent appointed by the
Company) shall return to the Company any cash that remains unclaimed as provided in Section 14.04.

the Notes and this Indenture may be served. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such office or agency not designated or
appointed by the Trustee. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust Office.

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

     The Company hereby initially designates the Trustee as paying agent, Note Registrar, Custodian
and conversion agent and the Corporate Trust Office shall be considered as one such office or
agency of the Company for each of the aforesaid purposes.

mailed, the notices set forth in Section 9.10(a) and the third paragraph of Section 9.11. If
co-registrars have been appointed in accordance with this Section, the Trustee shall mail such
notices only to the Company and the holders of Notes it can identify from its records.

22

 

     Section 6.03. Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever
necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided
in Section 9.10, a Trustee, so that there shall at all times be a Trustee hereunder.

     Section 6.04. Provisions as to Paying Agent. (a) If the Company shall appoint a paying agent

such paying agent to execute and deliver to the Trustee an instrument in which such agent shall
agree with the Trustee, subject to the provisions of this Section 6.04:

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

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

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

     The Company shall, on or before each due date of the principal of, premium, if any, or
interest on the Notes, deposit with the paying agent a sum (in funds which are immediately
available on the due date for such payment) sufficient to pay such principal, premium, if any, or
interest, and (unless such paying agent is the Trustee) the Company will promptly notify the
Trustee of any failure to take such action; provided that if such deposit is made on the due date,
such deposit shall be received by the paying agent by 10:00 a.m. New York City time, on such date.

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

     (c) Anything in this Section 6.04 to the contrary notwithstanding, the Company may, at any
time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other
reason, pay or cause to be paid to the

23

 

Trustee all sums held in trust by the Company or any paying
agent hereunder as required by this Section 6.04, such sums to be held by the Trustee upon the
trusts herein contained and upon such payment by the Company or any paying agent to the Trustee,
the Company or such paying agent shall be released from all further liability with respect to such
sums.

     (d) Anything in this Section 6.04 to the contrary notwithstanding, the agreement to hold sums
in trust as provided in this Section 6.04 is subject to Sections 14.03 and 14.04.

     The Trustee shall not be responsible for the actions of any other paying agents (including the
Company if acting as its own paying agent) and shall have no control of any funds held by such
other paying agents.

     Section 6.05. Existence. Subject to Article 13, the Company will do or cause to be done all
things
necessary to preserve and keep in full force and effect its existence and rights (charter and
statutory); provided that the Company shall not be required to preserve any such right if the
Company shall determine that the preservation thereof is no longer desirable in the conduct of the
business of the Company and that the loss thereof is not disadvantageous in any material respect to
the Noteholders.

     Section 6.06. Maintenance of Properties. The Company will cause all properties used or useful
in the conduct of its business or the business of any Significant Subsidiary to be maintained and
kept in good condition, repair and working order and supplied with all necessary equipment and will
cause to be made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times; provided that
nothing in this Section shall prevent the Company from discontinuing the operation or maintenance
of any of such properties if such discontinuance is, in the judgment of the Company, desirable in
the conduct of its business or the business of any subsidiary and not disadvantageous in any
material respect to the Noteholders.

     Section 6.07. Payment of Taxes and Other Claims. The Company will pay or discharge, or cause
to be paid or discharged, before the same may become delinquent, (i) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Significant Subsidiary or upon the
income, profits or property of the Company or any Significant Subsidiary, (ii) all claims for
labor, materials and supplies which, if unpaid, might by law become a lien or charge upon the
property of the Company or any Significant Subsidiary and (iii) all stamp taxes and other duties,
if any, which may be imposed by the United States or any political subdivision thereof or therein
in connection with the issuance, transfer, exchange, conversion or redemption of any Notes or with
respect to this

24

 

Indenture; provided that, in the case of clauses (i) and (ii), the Company shall
not be required to pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim (A) if the failure to do so will not, in the aggregate, have a material adverse
impact on the Company, or (B) if the amount, applicability or validity is being contested in good
faith by appropriate proceedings.

     Section 6.08. Reserved.

     Section 6.09. Stay, Extension and Usury Laws. The Company covenants (to the extent that it
may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay,
extension or usury law or other law which would prohibit or forgive the Company from paying

upon receipt of a new list so furnished.

     (b) The rights of Noteholders to communicate with other holders of Notes with respect to their

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

ARTICLE 8

order, rule or regulation of any administrative or governmental body) shall have occurred and be
continuing:

     (a) default in the payment of any installment of interest upon any of the Notes as and when
the same shall become due and payable, and continuance of such default for a period of thirty (30)
days; or

     (b) default in the payment of the principal of or premium, if any, on any of the Notes as and
when the same shall become due and payable either at maturity or in connection with any redemption
pursuant to Article 3, by acceleration or otherwise; or

     (c) default in the Company’s obligation to convert any Notes following the exercise by the
Noteholder of the right to convert such Notes into Common Stock pursuant to and in accordance with
Article 16; or

27

 

     (d) default in the Company’s obligation to provide a Designated Event Notice upon a Designated
Event as provided in Section 3.05; or

     (e) failure on the part of the Company duly to observe or perform any other of the covenants
or agreements on the part of the Company in the Notes or in this Indenture (other than a covenant
or agreement a default in whose performance or whose breach is elsewhere in this Section 8.01
specifically dealt with) continued for a period of sixty (60) days after the date on which written
notice of such failure, requiring the Company to remedy the same, shall have been given to the
Company by the Trustee, or the Company and a Responsible Officer of the Trustee by the holders of
at least twenty-five percent (25%) in aggregate principal amount of the Notes at the time
outstanding determined in accordance with Section 10.04; or

     (f) the Company shall commence a voluntary case or other proceeding seeking liquidation,
reorganization or other relief with respect to the Company or its debts under any bankruptcy,
insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee,
receiver, liquidator, custodian or other similar official of the Company or any substantial part of
the property of the Company, or shall consent to any such relief or to the appointment of or taking
possession by any such official in an involuntary case or other proceeding commenced against the
Company, or shall make a general assignment for the benefit of creditors, or shall fail generally
to pay its debts as they become due; or

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

     (h) default in the payment of principal when due at stated maturity or resulting in
acceleration of other Indebtedness of the Company for borrowed money where the aggregate principal
amount with respect to which the default or acceleration has occurred exceeds $10 million and such
acceleration has not been rescinded or annulled within a period of 30 days after written notice of
such failure, requiring the Company to remedy the same, shall have been given to the Company by the
Trustee, or to the Company and the Trustee by the holders of at least 25% in aggregate principal
amount of the Notes at the time outstanding determined in accordance with Section 10.04;

then, and in each and every such case (other than an Event of Default specified in Section 8.01(f)
or 8.01(g)), unless the principal of all of the Notes shall have

28

 

already become due and payable,
either the Trustee or the holders of not less than twenty-five percent (25%) in aggregate principal
amount of the Notes then outstanding hereunder determined in accordance with Section 10.04, by
notice in
writing to the Company (and to the Trustee if given by Noteholders), may declare the principal of
and premium, if any, on all the Notes and the interest accrued thereon to be due and payable
immediately, and upon any such declaration the same shall become and shall be immediately due and
payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding. If
an Event of Default specified in Section 8.01(f) or 8.01(g) occurs, the principal of all the Notes
and the interest accrued thereon shall be immediately and automatically due and payable without
necessity of further action. This provision, however, is subject to the conditions that if, at any
time after the principal of the Notes shall have been so declared due and payable, and before any
judgment or decree for the payment of the monies due shall have been obtained or entered as
hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to
pay all matured installments of interest upon all Notes and the principal of and premium, if any,
on any and all Notes which shall have become due otherwise than by acceleration (with interest on
overdue installments of interest (to the extent that payment of such interest is enforceable under
applicable law) and on such principal and premium, if any, at the rate borne by the Notes, to the
date of such payment or deposit) and amounts due to the Trustee pursuant to Section 9.06, and if
any and all defaults under this Indenture, other than the nonpayment of principal of and premium,
if any, and accrued interest on Notes which shall have become due by acceleration, shall have been
cured or waived pursuant to Section 8.07, then and in every such case the holders of a majority in
aggregate principal amount of the Notes then outstanding, by written notice to the Company and to
the Trustee, may waive all defaults or Events of Default and rescind and annul such declaration and
its consequences; but no such waiver or rescission and annulment shall extend to or shall affect
any subsequent default or Event of Default, or shall impair any right consequent thereon. The
Company shall notify in writing a Responsible Officer of the Trustee, promptly upon becoming aware
thereof, of any Event of Default.

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

     Section 8.02. Payments of Notes on Default; Suit Therefor. The Company covenants that (a) in
case default shall be made in the payment of any installment of interest upon any of the Notes as
and when the same shall become

29

 

due and payable, and such default shall have continued for a period
of thirty (30) days, or (b) in case default shall be made in the payment of the principal of or
premium, if
any, on any of the Notes as and when the same shall have become due and payable, whether at
maturity of the Notes or in connection with any redemption, by or under this Indenture, declaration
or otherwise, then, upon demand of the Trustee, the Company will pay to the Trustee, for the
benefit of the holders of the Notes, the whole amount that then shall have become due and payable
on all such Notes for principal and premium, if any, or interest as the case may be, with interest
upon the overdue principal and premium, if any, and (to the extent that payment of such interest is
enforceable under applicable law) upon the overdue installments of interest at the rate borne by
the Notes, plus 1% and, in addition thereto, such further amount as shall be sufficient to cover
the costs and expenses of collection, including reasonable compensation to the Trustee, its agents,
attorneys and counsel, and all other amounts due the Trustee under Section 9.06. Until such demand
by the Trustee, the Company may pay the principal of and premium, if any, and interest on the Notes
to the registered holders, whether or not the Notes are overdue.

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

     In case there shall be pending proceedings for the bankruptcy or for the reorganization of the
Company or any other obligor on the Notes under Title 11 of the United States Code, or any other
applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or taken possession of
the Company or such other obligor, the property of the Company or such other obligor, or in the
case of any other judicial proceedings relative to the Company or such other obligor upon the
Notes, or to the creditors or property of the Company or such other obligor, the Trustee,
irrespective of whether the principal of the Notes shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made
any demand pursuant to the provisions of this Section 8.02, shall be entitled and empowered, by
intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole
amount of principal, premium, if any, and interest owing and unpaid in respect of the Notes, and,
in case of any judicial proceedings, to file such proofs of claim and other papers or documents as
may be necessary or advisable in order to have the claims of the Trustee and of the Noteholders
allowed in such judicial

30

 

proceedings relative to the Company or any other obligor on the Notes, its
or their creditors, or its or their property, and to collect and receive any monies or other
property payable or deliverable on any such claims, and to distribute the same after the
deduction of any amounts due the Trustee under Section 9.06, and to take any other action with
respect to such claims, including participating as a member of any official committee of creditors,
as it reasonably deems necessary or advisable, and, unless prohibited by law or applicable
regulations, and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
custodian or similar official is hereby authorized by each of the Noteholders to make such payments
to the Trustee, and, in the event that the Trustee shall consent to the making of such payments
directly to the Noteholders, to pay to the Trustee any amount due it for reasonable compensation,
expenses, advances and disbursements, including counsel fees and expenses incurred by it up to the
date of such distribution. To the extent that such payment of reasonable compensation, expenses,
advances and disbursements out of the estate in any such proceedings shall be denied for any
reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all
distributions, dividends, monies, securities and other property which the holders of the Notes may
be entitled to receive in such proceedings, whether in liquidation or under any plan of
reorganization or arrangement or otherwise.

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

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

     Section 8.03. Application of Monies Collected By Trustee. Any monies collected by the Trustee
pursuant to this Article 8 shall be applied in the order following, at the date or dates fixed by
the Trustee for the distribution of such monies, upon presentation of the several Notes, and
stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 9.06;

31

 

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

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

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

     Section 8.04. Proceedings by Noteholder. No Noteholder shall have any right by virtue of or
by reference to any provision of this Indenture to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Indenture, or for the appointment of a
receiver, trustee, liquidator, custodian or other similar official, or for any other remedy
hereunder, unless such holder previously shall have given to the Trustee written notice of an Event
of Default and of the continuance thereof, as hereinbefore provided, and unless also the holders of
not less than twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding
shall have made written request upon the Trustee to institute such action, suit or proceeding in
its own name as Trustee hereunder and shall have offered to the Trustee such reasonable security or
indemnity as it may require against the costs, expenses and liabilities to be incurred therein or
thereby, and the Trustee for sixty (60) days after its receipt of such notice, request and offer of
indemnity, shall have neglected or refused to institute any such action, suit or proceeding and no
direction inconsistent with such written request shall have been given to the Trustee pursuant to
Section 8.07; it being understood and intended, and being expressly covenanted by the taker and
holder of every Note with every other taker and holder and the Trustee, that no one or more
Noteholders shall have any right in any manner whatever by virtue of or by reference to any
provision of this Indenture to affect, disturb or prejudice the rights of any other holder of
Notes, or to obtain or seek to obtain priority over or

32

 

preference to any other such holder, or to
enforce any right under this Indenture,
except in the manner herein provided and for the equal, ratable and common benefit of all
Noteholders (except as otherwise provided herein). For the protection and enforcement of this
Section 8.04, each and every Noteholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

     Notwithstanding any other provision of this Indenture and any provision of any Note, the right
of any Noteholder to receive payment of the principal of and premium, if any (including the
redemption price upon redemption pursuant to Article 8), and accrued interest on such Note, on or
after the respective due dates expressed in such Note or in the event of redemption, or to
institute suit for the enforcement of any such payment on or after such respective dates against
the Company shall not be impaired or affected without the consent of such Noteholder.

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

     Section 8.05. Proceedings By Trustee. In case of an Event of Default, the Trustee may, in its
discretion, proceed to protect and enforce the rights vested in it by this Indenture by such
appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either
by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the
specific enforcement of any covenant or agreement contained in this Indenture or in aid of the
exercise of any power granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law.

     Section 8.06. Remedies Cumulative And Continuing. Except as provided in Section 2.06, all
powers and remedies given by this Article 8 to the Trustee or to the Noteholders shall, to the
extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other
powers and remedies available to the Trustee or the Noteholders, by judicial proceedings or
otherwise, to enforce the performance or observance of the covenants and agreements contained in
this Indenture, and no delay or omission of the Trustee or of any Noteholder to exercise any right
or power accruing upon any default or Event of Default occurring and continuing as aforesaid shall
impair any such right or power, or shall be construed to be a waiver of any such default or any
acquiescence therein, and, subject to the provisions of Section 8.04, every power and remedy given
by this Article 8 or by law to the Trustee or to the Noteholders may be exercised
from time to time, and as often as shall be deemed expedient, by the Trustee or by the
Noteholders.

33

 

     Section 8.07. Direction of Proceedings and Waiver of Defaults By Majority of Noteholders. The
holders of a majority in aggregate principal amount of the Notes at the time outstanding determined
in accordance with Section 10.04 shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising any trust or power
conferred on the Trustee; provided that (a) such direction shall not be in conflict with any rule
of law or with this Indenture, (b) the Trustee may take any other action which is not inconsistent
with such direction, (c) the Trustee may decline to take any action that would benefit some
Noteholder to the detriment of other Noteholders and (d) the Trustee may decline to take any action
that would involve the Trustee in personal liability. The holders of a majority in aggregate
principal amount of the Notes at the time outstanding determined in accordance with Section 10.04
may, on behalf of the holders of all of the Notes, waive any past default or Event of Default
hereunder and its consequences except (i) a default in the payment of Interest or premium, if any,
on, or the principal of, the Notes, (ii) a failure by the Company to convert any Notes into Common
Stock, (iii) a default in the payment of the redemption price pursuant to Article 3 or (iv) a
default in respect of a covenant or provisions hereof which under Article 12 cannot be modified or
amended without the consent of the holders of each or all Notes then outstanding or affected
thereby. Upon any such waiver, the Company, the Trustee and the holders of the Notes shall be
restored to their former positions and rights hereunder; but no such waiver shall extend to any
subsequent or other default or Event of Default or impair any right consequent thereon. Whenever
any default or Event of Default hereunder shall have been waived as permitted by this Section 8.07,
said default or Event of Default shall for all purposes of the Notes and this Indenture be deemed
to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

     Section 8.08. Notice of Defaults. The Trustee shall, within ninety (90) days after a
Responsible Officer of the Trustee has knowledge of the occurrence of a default, mail to all
Noteholders, as the names and addresses of such holders appear upon the Note Register, notice of
all defaults known to a Responsible Officer, unless such defaults shall have been cured or waived
before the giving of such notice; provided that except in the case of Default in the payment of the
principal of, or premium, if any, or interest on any of the Notes, the Trustee shall be protected
in withholding such notice if and so long as a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determines that the withholding of such notice is in the
interests of the Noteholders.

     Section 8.09. Undertaking To Pay Costs. All parties to this Indenture agree, and each
Noteholder by his acceptance thereof shall be deemed to have agreed, that any court may, in its
discretion, require, in any suit for the enforcement of any right or remedy under this Indenture,
or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by
any party

34

 

litigant in such suit of an undertaking to pay the costs of such suit and that such court
may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses,
against any party litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; provided that the provisions of this Section 8.09
(to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit
instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than ten
percent in principal amount of the Notes at the time outstanding determined in accordance with
Section 10.04, or to any suit instituted by any Noteholder for the enforcement of the payment of
the principal of or premium, if any, or interest on any Note on or after the due date expressed in
such Note or to any suit for the enforcement of the right to convert any Note in accordance with
the provisions of Article 16.

ARTICLE 9

The Trustee

     Section 9.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of
an Event of Default and after the curing of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set forth in this
Indenture. In case an Event of Default has occurred (which has not been cured or waived), the
Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the
same degree of care and skill in their exercise, as a prudent person would exercise or use under
the circumstances in the conduct of his own affairs.

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

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

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

     (ii) in the absence of bad faith and willful misconduct on the part of the Trustee,
the Trustee may conclusively rely as to the truth of the statements and the correctness of
the opinions expressed therein, upon any certificates or opinions furnished to the Trustee
and conforming to the requirements of this Indenture; but, in the case of any such
certificates or

35

 

opinions which by any provisions hereof are specifically required to be
furnished to the Trustee, the Trustee shall be under a duty to examine the same to
determine whether or not they conform to the requirements of this Indenture (but need not
confirm or investigate the accuracy of mathematical calculations or other facts stated
therein);

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

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

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

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

     (f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to
this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its
failure to receive such notice as reason to act as if no such event occurred; and

     (g) the Trustee shall not be deemed to have knowledge of any Default or Event of Default
hereunder unless it shall have been notified in writing of such Default or Event of Default by the
Company or the holders of at least 10% in aggregate principal amount of the Notes.

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

     Section 9.02. Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section
9.01:

36

 

     (a) the Trustee may conclusively rely and shall be protected in acting upon any resolution,

     (d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in
it by this Indenture at the request, order or direction of any of the Noteholders pursuant to the

security or indemnity satisfactory to it against the costs, expenses and liabilities which may be
incurred therein or thereby;

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

     (f) the Trustee may execute any of the trusts or powers hereunder or perform any duties

and the Trustee shall not be responsible for any misconduct or negligence on the part of any

other Person employed to act hereunder;

     (i) the Trustee may request that the Company deliver an Officers’ Certificate setting forth
the names of individuals and/or titles of officers authorized at such time to take specified

irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action.

     Section 9.03. No Responsibility For Recitals, Etc. The recitals contained herein and in the
Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of
the Company, and the Trustee assumes no responsibility for the correctness of the same. The
Trustee makes no representations as to the validity or sufficiency of this Indenture or of the
Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes
or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the
provisions of this Indenture.

     Section 9.04. Trustee, Paying Agents, Conversion Agents or Registrar May Own Notes. The
Trustee, any paying agent, any conversion agent or Note Registrar, in its individual or any other
capacity, may become the owner or pledgee of Notes with the same rights it would have if it were

     Section 9.05. Monies to Be Held in Trust. Subject to the provisions of Section 14.04, all
monies received by the Trustee shall, until used or applied as herein provided, be held in trust
for the purposes for which they were received. Money held by the Trustee in trust hereunder need

under no liability for interest on any money received by it hereunder except as may be agreed in
writing from time to time by the Company and the Trustee.

     Section 9.06. Compensation and Expenses of Trustee. The Company covenants and agrees to pay
to the Trustee from time to time, and the Trustee shall be entitled to, such compensation for all
services rendered by it hereunder in any capacity (which shall not be limited by any provision of
law in regard to the compensation of a trustee of an express trust) as mutually agreed to from time
to

38

 

time in writing between the Company and the Trustee, and the Company will pay or reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances reasonably
incurred or made by the Trustee in accordance with any of the provisions of this Indenture
(including the reasonable compensation and the expenses and disbursements of its counsel and of all
Persons not regularly in its employ) except any such expense, disbursement or advance as may arise
from its negligence or bad faith. The Company also covenants to indemnify the Trustee and any
predecessor Trustee (and any officer, director or employee of the Trustee), in any capacity under
this Indenture and its agents and any authenticating agent for, and to hold them harmless against,
any and all loss, liability, damage, claim or expense including taxes (other than taxes based on
the income of the Trustee) incurred without negligence or bad faith on the part of the Trustee or
such officers, directors, employees and agent or authenticating agent, as the case may be, and
arising out of or in connection with the acceptance or administration of this trust or in any other
capacity hereunder, including the costs and expenses of defending themselves against any claim
(whether asserted by the Company, any holder or any other Person) or liability in connection with
enforcing the provisions of the Section 9.06, except to the extent that such loss, damage, claim,
liability or expense is due to its own negligence or bad faith. The obligations of the Company
under this Section 9.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee
for expenses, disbursements and advances shall be secured by a lien prior to that of the Notes upon
all property and funds held or collected by the Trustee as such, except funds held in trust for the
benefit of the holders of particular Notes. The obligation of the Company under this Section shall
survive the satisfaction and discharge of this Indenture.

     When the Trustee and its agents and any authenticating agent incur expenses or render services
after an Event of Default specified in Section 8.01(f) or (g) with respect to the Company occurs,
the expenses and the compensation for
the services are intended to constitute expenses of administration under any bankruptcy,
insolvency or similar laws.

     Section 9.07. Officers’ Certificate As Evidence. Except as otherwise provided in Section
9.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or omitting any
action hereunder, such matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of bad faith or willful misconduct on the part of the Trustee, be
deemed to be conclusively proved and established by an Officers’ Certificate delivered to the
Trustee.

     Section 9.08. Conflicting Interests of Trustee. If the Trustee has or shall acquire a
conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the

39

 

manner provided by, and subject to the
provisions of, the Trust Indenture Act and this Indenture.

     Section 9.09. Eligibility of Trustee. There shall at all times be a Trustee hereunder which
shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a
combined capital and surplus of at least $50,000,000 (or if such Person is a member of a bank
holding company system, its bank holding company shall have a combined capital and surplus of at
least $50,000,000). If such Person publishes reports of condition at least annually, pursuant to
law or to the requirements of any supervising or examining authority, then for the purposes of this
Section the combined capital and surplus of such Person shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this Section 9.09, it shall
resign immediately in the manner and with the effect hereinafter specified in this Article.

     Section 9.10. Resignation or Removal of Trustee.

     (a) The Trustee may at any time resign by giving written notice of such resignation to the
Company and to the holders of Notes. Upon receiving such notice of resignation, the Company shall
promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the
Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and
one copy to the successor trustee. If no successor trustee shall have been so appointed and have
accepted appointment sixty (60) days after the mailing of such notice of resignation to the
Noteholders, the resigning Trustee
may, upon ten (10) Business Days’ notice to the Company and the Noteholders, appoint a
successor identified in such notice or may petition, at the expense of the Company, any court of
competent jurisdiction for the appointment of a successor trustee, or, if any Noteholder who has
been a bona fide holder of a Note or Notes for at least six (6) months may, subject to the
provisions of Section 8.09, on behalf of himself and all others similarly situated, petition any
such court for the appointment of a successor trustee. Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

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

     (i) the Trustee shall fail to comply with Section 9.08 after written request therefor
by the Company or by any Noteholder who has been a bona fide holder of a Note or Notes for
at least six (6) months; or

     (ii) the Trustee shall cease to be eligible in accordance with the provisions of
Section 9.09 and shall fail to resign after written request therefor by the Company or by
any such Noteholder; or

40

 

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

then, in any such case, the Company may remove the Trustee and appoint a successor trustee by
written instrument, in duplicate, executed by order of the Board of Directors, one copy of which
instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or,
subject to the provisions of Section 8.09, any Noteholder who has been a bona fide holder of a Note
or Notes for at least six (6) 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; provided that if no successor Trustee shall have been appointed and have
accepted appointment sixty (60) days after either the Company or the Noteholders has removed the
Trustee, or the Trustee resigns, the Trustee so removed may petition, at the expense of the
Company, any court of competent jurisdiction for an appointment of a successor trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee
and appoint a successor trustee.

     (c) The holders of a majority in aggregate principal amount of the Notes at the time
outstanding may at any time remove the Trustee and nominate a successor trustee which shall be
deemed appointed as successor trustee unless, within ten (10) days after notice to the Company of
such nomination, the Company objects thereto, in which case the Trustee so removed or any
Noteholder, or if such Trustee so removed or any Noteholder fails to act, the Company, upon
the terms and conditions and otherwise as in Section 9.10(a) provided, may petition any court of
competent jurisdiction for an appointment of a successor trustee.

     (d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant
to any of the provisions of this Section 9.10 shall become effective upon acceptance of appointment
by the successor trustee as provided in Section 9.11.

     (e) Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s
obligations under Section 9.06 shall continue for the benefit of the retiring Trustee.

     Section 9.11. Acceptance by Successor Trustee. Any successor trustee appointed as provided in
Section 9.10 shall execute, acknowledge and deliver to the Company and to its predecessor trustee
an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without any

41

 

further act,
deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as trustee herein; but,
nevertheless, on the written request of the Company or of the successor trustee, the trustee
ceasing to act shall, upon payment of any amount then due it pursuant to the provisions of Section
9.06, execute and deliver an instrument transferring to such successor trustee all the rights and
powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company
shall execute any and all instruments in writing for more fully and certainly vesting in and
confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall,
nevertheless, retain a lien upon all property and funds held or collected by such trustee as such,
except for funds held in trust for the benefit of holders of particular Notes, to secure any
amounts then due it pursuant to the provisions of Section 9.06.

     No successor trustee shall accept appointment as provided in this Section 9.11 unless, at the
time of such acceptance, such successor trustee shall be qualified under the provisions of Section
9.08 and be eligible under the provisions of Section 9.09.

     Upon acceptance of appointment by a successor trustee as provided in this Section 9.11, the
Company (or the former trustee, at the written direction of the Company) shall mail or cause to be
mailed notice of the succession of such trustee hereunder to the holders of Notes at their
addresses as they shall appear on the Note Register. If the Company fails to mail such notice
within ten (10) days after
acceptance of appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Company.

     Section 9.12. Succession By Merger. Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to
all or substantially all of the corporate trust business of the Trustee (including any trust
created by this Indenture), shall be the successor to the Trustee hereunder without the execution
or filing of any paper or any further act on the part of any of the parties hereto, provided that
in the case of any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, such corporation shall be qualified under the provisions of Section 9.08
and eligible under the provisions of Section 9.09.

     In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to
the Trustee may adopt the certificate of authentication of any predecessor trustee or
authenticating agent appointed by such predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been authenticated, any
successor to the

42

 

Trustee or any authenticating agent appointed by such successor trustee may
authenticate such Notes in the name of the successor trustee; and in all such cases such
certificates shall have the full force that is provided in the Notes or in this Indenture; provided
that the right to adopt the certificate of authentication of any predecessor Trustee or
authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or
successors by merger, conversion or consolidation.

     Section 9.13. Preferential Collection of Claims. If and when the Trustee shall be or become a
creditor of the Company (or any other obligor upon the Notes), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of the claims against the Company
(or any such other obligor).

ARTICLE 10

The Noteholders

     Section 10.01. Action By Noteholders. Whenever in this Indenture it is provided that the
holders of a specified percentage in aggregate principal amount of the Notes may take any action
(including the making of any demand or request, the giving of any notice, consent or waiver or the
taking of any other action), the fact that at the
time of taking any such action, the holders of such specified percentage have joined therein
may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by
Noteholders in person or by agent or proxy appointed in writing, or (b) by the record of the
holders of Notes voting in favor thereof at any meeting of Noteholders duly called and held in
accordance with the provisions of Article 11, or (c) by a combination of such instrument or
instruments and any such record of such a meeting of Noteholders. Whenever the Company or the
Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee
may fix in advance of such solicitation, a date as the record date for determining holders entitled
to take such action. The record date shall be not more than fifteen (15) days prior to the date of
commencement of solicitation of such action.

     Section 10.02. Proof of Execution by Noteholders. Subject to the provisions of Sections 9.01,
9.02 and 11.05, proof of the execution of any instrument by a Noteholder or its agent or proxy
shall be sufficient if made in accordance with such reasonable rules and regulations as may be
prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding
of Notes shall be proved by the registry of such Notes or by a certificate of the Note Registrar.

     The record of any Noteholders’ meeting shall be proved in the manner provided in Section
11.06.

43

 

     Section 10.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any paying agent,
any conversion agent and any Note Registrar may deem the Person in whose name such Note shall be
registered upon the Note Register to be, and may treat it as, the absolute owner of such Note
(whether or not such Note shall be overdue and notwithstanding any notation of ownership or other
writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of
receiving payment of or on account of the principal of, premium, if any, and interest on such Note,
for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor
any paying agent nor any conversion agent nor any Note Registrar shall be affected by any notice to
the contrary. All such payments so made to any holder for the time being, or upon his order, shall
be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for monies payable upon any such Note.

     Section 10.04. Company-owned Notes Disregarded. In determining whether the holders of the
requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or
other action under this Indenture, Notes which are owned by the Company or any other obligor on the
Notes or any Affiliate of
the Company or any other obligor on the Notes shall be disregarded and deemed not to be
outstanding for the purpose of any such determination; provided that for the purposes of
determining whether the Trustee shall be protected in relying on any such direction, consent,
waiver or other action, only Notes which a Responsible Officer actually knows are so owned shall be
so disregarded. Notes so owned which have been pledged in good faith may be regarded as
outstanding for the purposes of this Section 10.04 if the pledgee shall establish to the
satisfaction of the Trustee the pledgee’s right to vote such Notes and that the pledgee is not the
Company, any other obligor on the Notes or any Affiliate of the Company or any such other obligor.
In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of
counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall
furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any,
known by the Company to be owned or held by or for the account of any of the above described
Persons, and, subject to Section 9.01, the Trustee shall be entitled to accept such Officers’
Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes
not listed therein are outstanding for the purpose of any such determination.

     Section 10.05. Revocation Of Consents, Future Holders Bound. At any time prior to (but not
after) the evidencing to the Trustee, as provided in Section 10.01, of the taking of any action by
the holders of the percentage in aggregate principal amount of the Notes specified in this
Indenture in connection with such action, any holder of a Note which is shown by the evidence to be
included in the Notes the holders of which have consented to such action may, by filing written
notice with the Trustee at its Corporate Trust Office and upon proof of holding as

44

 

provided in
Section 10.02, revoke such action so far as concerns such Note. Except as aforesaid, any such
action taken by the holder of any Note shall be conclusive and binding upon such holder and upon
all future holders and owners of such Note and of any Notes issued in exchange or substitution
therefor, irrespective of whether any notation in regard thereto is made upon such Note or any Note
issued in exchange or substitution therefor.

ARTICLE 11

meeting and the establishment of any record date pursuant to Section 10.01, shall be mailed to
holders of Notes at their addresses as they shall appear on the Note Register. Such notice shall
also be mailed to the Company. Such notices shall be mailed not less than twenty (20) nor more
than ninety (90) days prior to the date fixed for the meeting.

     Any meeting of Noteholders shall be valid without notice if the holders of all Notes then

proxies, certificates and other evidence of the right to vote, and such other matters concerning

proxy to vote on behalf of other Noteholders. Any meeting of Noteholders duly called pursuant to
the provisions of Section 11.02 or 11.03 may be adjourned from time to time by the holders of a
majority of the aggregate principal amount of Notes represented at the meeting, whether or not
constituting a quorum, and the meeting may be held as so adjourned without further notice.

more persons having knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was mailed as provided in Section 11.02. The record shall show the

enforcement of all or any of the several remedies provided in this Indenture as herein set forth;
provided that in respect of any such additional covenant, restriction or condition, such

be shorter or longer than that allowed in the case of other defaults) or may provide for an
immediate enforcement upon such default or may limit the remedies available to the Trustee upon
such default;

     (e) to provide for the issuance under this Indenture of Notes in coupon form (including Notes

of Directors certified by its Secretary or Assistant

48

 

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

     Any supplemental indenture authorized by the provisions of this Section 12.01 may be executed
by the Company and the Trustee without the consent of the holders of any of the Notes at the time
outstanding, notwithstanding any of the provisions of Section 12.02.

     Section 12.02. Supplemental Indenture With Consent Of Noteholders. With the consent
(evidenced as provided in Article 10) of the holders of at least a majority in aggregate principal
amount of the Notes at the time outstanding, the Company, when authorized by the resolutions of the
Board of Directors, and the Trustee may, from time to time and at any time, enter into an indenture
or indentures supplemental hereto for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Indenture or any supplemental indenture or of
modifying in any manner the rights of the holders of the Notes; provided that no such supplemental
indenture shall, without the consent of the holder of each Note so affected, (i) extend the fixed
maturity of any Note, (ii) reduce the rate or extend the time of payment of interest thereon, (iii)
reduce the principal amount thereof or premium, if any, thereon, or reduce any amount payable on
redemption thereof, (iv) impair the right of any Noteholder to institute suit for the payment
thereof, (v) make the principal thereof or interest or premium, if any, thereon payable in any coin
or currency other than that provided in the Notes, (vi) change the obligation of the Company to
redeem any Note upon the happening of a Designated Event in a manner adverse to the Noteholders,
(vii) impair the right to convert the Notes or
reduce the number of shares of Common Stock or the amount of any other property receivable
upon conversion, subject to the terms set forth herein, including Section 16.06, in each case,
(viii) modify any of the provisions of this Section 12.02 or Section 8.07, except to increase any
such percentage or to provide that certain other provisions of this Indenture cannot be modified or
waived without the consent of the holder of each Note so affected, (ix) change any obligation of
the Company to maintain an office or agency in the places and for the purposes set forth in Section
6.02, (x) reduce the quorum or voting requirements set forth in Article 11 or (xi) reduce the
aforesaid percentage of Notes, the holders of which are required to consent to any such
supplemental indenture.

     Upon the written request of the Company, accompanied by a copy of the resolutions of the Board
of Directors certified by its Secretary or Assistant Secretary authorizing the execution of any
such supplemental indenture, and upon

49

 

the filing with the Trustee of evidence of the consent of
Noteholders as aforesaid, the Trustee shall join with the Company in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties
or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion,
but shall not be obligated to, enter into such supplemental indenture.

     It shall not be necessary for the consent of the Noteholders under this Section 12.02 to
approve the particular form of any proposed supplemental indenture, but it shall be sufficient if
such consent shall approve the substance thereof.

     Section 12.03. Effect Of Supplemental Indenture. Any supplemental indenture executed pursuant
to the provisions of this Article 12 shall comply with the Trust Indenture Act, as then in effect,
provided that this Section 12.03 shall not require such supplemental indenture or the Trustee to be
qualified under the Trust Indenture Act prior to the time such qualification is in fact required
under the terms of the Trust Indenture Act or the Indenture has been qualified under the Trust
Indenture Act, nor shall it constitute any admission or acknowledgment by any party to such
supplemental indenture that any such qualification is required prior to the time such qualification
is in fact required under the terms of the Trust Indenture Act or the Indenture has been qualified
under the Trust Indenture Act. Upon the execution of any supplemental indenture pursuant to the
provisions of this Article 12, this Indenture shall be and be deemed to be modified and amended in
accordance therewith and the respective rights, limitation of rights, obligations, duties and
immunities under this Indenture of the Trustee, the Company and the holders of Notes shall
thereafter be determined, exercised and enforced hereunder, subject in all respects to such
modifications and amendments and all the terms
and conditions of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

     Section 12.04. Notation On Notes. Notes authenticated and delivered after the execution of
any supplemental indenture pursuant to the provisions of this Article 12 may bear a notation in
form approved by the Trustee as to any matter provided for in such supplemental indenture. If the
Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of
the Trustee and the Board of Directors, to any modification of this Indenture contained in any such
supplemental indenture may, at the Company’s expense, be prepared and executed by the Company,
authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to
Section 17.10) and delivered in exchange for the Notes then outstanding, upon surrender of such
Notes then outstanding.

     Section 12.05. Evidence Of Compliance Of Supplemental Indenture To Be Furnished To Trustee.
Prior to entering into any supplemental indenture, the

50

 

Trustee shall be provided with an Officers’
Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture
executed pursuant hereto complies with the requirements of this Article 12 and is otherwise
authorized or permitted by this Indenture.

ARTICLE 13

Consolidation, Merger, Sale, Conveyance And Lease

     Section 13.01. Company May Consolidate On Certain Terms. Subject to the provisions of Section
13.02, the Company shall not consolidate or merge with or into any other Person or Persons (whether
or not affiliated with the Company), nor shall the Company or its successor or successors be a
party or parties to successive consolidations or mergers, nor shall the Company sell, convey,
transfer or lease the property and assets of the Company substantially as an entirety, to any other
Person (whether or not affiliated with the Company), unless: (i) the Company is the surviving
Person, or the resulting, surviving or transferee Person is organized and existing under the laws
of the United States of America, any state thereof or the District of Columbia; (ii) upon any such
consolidation, merger, sale, conveyance, transfer or lease, the due and punctual payment of the
principal of and premium, if any, and interest on all of the Notes, according to their tenor and
the due and punctual performance and observance of all of the covenants and conditions of this
Indenture to be performed by the Company, shall be expressly assumed, by supplemental indenture
satisfactory in form to the Trustee, executed and delivered to the Trustee, by the Person (if other
than the Company) formed by such consolidation, or into which the Company shall have been
merged, or by the Person that shall have acquired or leased such property, and such supplemental
indenture shall provide for the applicable conversion rights set forth in Section 16.06; and (iii)
immediately after giving effect to the transaction described above, no Event of Default, and no
event which, after notice or lapse of time or both, would become an Event of Default, shall have
happened and be continuing.

     Section 13.02. Successor To Be Substituted. In case of any such consolidation, merger, sale,
conveyance, transfer or lease and upon the assumption by the successor Person, by supplemental
indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the
due and punctual payment of the principal of and premium, if any, and interest on all of the Notes
and the due and punctual performance of all of the covenants and conditions of this Indenture to be
performed by the Company, such successor Person shall succeed to and be substituted for the
Company, with the same effect as if it had been named herein as the party of this first part. Such
successor Person thereupon may cause to be signed, and may issue either in its own name or in the
name of AtheroGenics, Inc. any or all of the Notes, issuable hereunder that theretofore shall not
have been signed by the Company and delivered to the Trustee; and, upon the order of such successor
Person instead of the Company and subject to all the terms, conditions and limitations in this
Indenture prescribed, the

51

 

Trustee shall authenticate and shall deliver, or cause to be
authenticated and delivered, any Notes that previously shall have been signed and delivered by the
officers of the Company to the Trustee for authentication, and any Notes that such successor Person
thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes
so issued shall in all respects have the same legal rank and benefit under this Indenture as the
Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all
of such Notes had been issued at the date of the execution hereof. In the event of any such
consolidation, merger, sale, conveyance, transfer or lease, upon compliance with the provisions of
this Article 13, the Person named as the “Company” in the first paragraph of this Indenture or any
successor that shall thereafter have become such in the manner prescribed in this Article 13 may be
dissolved, wound up and liquidated at any time thereafter and such Person shall be released from
its liabilities as obligor and maker of the Notes and from its obligations under this Indenture.

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

     Section 13.03. Opinion Of Counsel To Be Given To Trustee. The Trustee
shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that
any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption
complies with the provisions of this Article 13.

ARTICLE 14

Satisfaction And Discharge Of Indenture

     Section 14.01. Discharge Of Indenture. When the Company shall deliver to the Trustee for
cancellation all Notes theretofore authenticated (other than any Notes that have been destroyed,
lost or stolen and in lieu of or in substitution for which other Notes shall have been
authenticated and delivered) and not theretofore canceled, or all the Notes not theretofore
canceled or delivered to the Trustee for cancellation shall have become due and payable, and the
Company shall deposit with the Trustee, in trust, funds sufficient to pay all of the Notes (other
than any Notes that shall have been mutilated, destroyed, lost or stolen and in lieu of or in
substitution for which other Notes shall have been authenticated and delivered) not theretofore
canceled or delivered to the Trustee for cancellation, including principal and premium, if any, and
interest due, and if the Company shall also pay or cause to be paid all other sums payable
hereunder by the Company, then this Indenture shall cease to be of further effect (except as to (i)
rights hereunder of Noteholders to receive payments of principal of and premium, if any, and
interest on, the Notes and the other rights, duties and obligations of Noteholders, as
beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee and (ii)
the rights, obligations and immunities

52

 

of the Trustee hereunder), and the Trustee, on written
demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel as required
by Section 17.05 and at the cost and expense of the Company, shall execute proper instruments
acknowledging satisfaction of and discharging this Indenture; the Company, however, hereby agrees
to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred by
the Trustee and to compensate the Trustee for any services thereafter reasonably and properly
rendered by the Trustee in connection with this Indenture or the Notes.

     Section 14.02. Deposited Monies To Be Held In Trust By Trustee. Subject to Section 14.04, all
monies deposited with the Trustee pursuant to Section 14.01, shall be held in trust for the sole
benefit of the Noteholders, and such monies shall be applied by the Trustee to the payment, either
directly or through any paying agent (including the Company if acting as its own paying agent), to
the holders of the particular Notes for the payment or redemption of which such monies have been
deposited with the Trustee, of all sums due and to become due thereon for principal and interest
and premium, if any.

     Section 14.03. Paying Agent To Repay Monies Held. Upon the satisfaction and discharge of this
Indenture, all monies then held by any paying agent of the Notes (other than the Trustee) shall,
upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such
paying agent shall be released from all further liability with respect to such monies.

     Section 14.04. Return Of Unclaimed Monies. Subject to the requirements of applicable law, any
monies deposited with or paid to the Trustee for payment of the principal of, premium, if any, or
interest on Notes and not applied but remaining unclaimed by the holders of Notes for two years
after the date upon which the principal of, premium, if any, or interest on such Notes, as the case
may be, shall have become due and payable, shall be repaid to the Company by the Trustee on demand
and all liability of the Trustee shall thereupon cease with respect to such monies; and the holder
of any of the Notes shall thereafter look only to the Company for any payment that such holder may
be entitled to collect unless an applicable abandoned property law designates another Person.

     Section 14.05. Reinstatement. If the Trustee or the paying agent is unable to apply any money
in accordance with Section 14.02 by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the Company’s
obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit
had occurred pursuant to Section 14.01 until such time as the Trustee or the paying agent is
permitted to apply all such money in accordance with Section 14.02; provided that if the Company
makes any payment of interest on or principal of any Note following the reinstatement of its
obligations, the Company shall be

53

 

subrogated to the rights of the holders of such Notes to receive
such payment from the money held by the Trustee or paying agent.

ARTICLE 15

Immunity Of Incorporators, Stockholders, Officers And Directors

     Section 15.01. Indenture And Notes Solely Corporate Obligations. No recourse for the payment
of the principal of or premium, if any, or Interest on any Note, or for any claim based thereon or
otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement
of the Company in this Indenture or in any supplemental indenture or in any Note, or because of the
creation of any indebtedness represented thereby, shall be had
against any incorporator, stockholder, employee, agent, officer, director or subsidiary, as
such, past, present or future, of the Company or of any successor corporation, either directly or
through the Company or any successor corporation, whether by virtue of any constitution, statute or
rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released as a condition of, and
as a consideration for, the execution of this Indenture and the issue of the Notes.

ARTICLE 16

Conversion Of Notes

     Section 16.01. Right To Convert.

     (a) Subject to and upon compliance with the provisions of this Indenture, at any time prior to
the close of business on March 1, 2011, the holder of any Note shall have the right, at such
holder’s option, to convert the principal amount of the Note, or any portion of such principal
amount which is a multiple of $1,000, into fully paid and non-assessable shares of Common Stock (as
such shares shall then be constituted) at the Conversion Rate in effect at such time, by surrender
of the Note so to be converted in whole or in part, together with any required funds, in the manner
provided in Section 16.02.

     (b) A Note in respect of which a holder is electing to exercise its option to require
redemption upon a Designated Event pursuant to Section 3.05 may be converted only if such holder
withdraws its Redemption Notice in accordance with Section 3.06. A holder of Notes is not entitled
to any rights of a holder of Common Stock until such holder has converted his Notes to Common
Stock, and only to the extent such Notes are deemed to have been converted to Common Stock under
this Article 16.

54

 

     Section 16.02. Exercise Of Conversion Privilege; Issuance Of Common Stock On Conversion; No
Adjustment For Interest Or Dividends.

     (a) In order to exercise the conversion privilege with respect to any Note in certificated
form, the Company must receive at the office or agency of the Company maintained for that purpose
or, at the option of such holder, the Corporate Trust Office, such Note with the original or
facsimile of the form entitled “Conversion Notice” on the reverse thereof, duly completed and
manually signed, together with such Notes duly endorsed for transfer, accompanied by the funds, if
any, required by Section 16.02(c). Such notice shall also state the name or names (with address or
addresses) in which the certificate
or certificates for shares of Common Stock which shall be issuable on such conversion shall be
issued, and shall be accompanied by transfer or similar taxes, if required pursuant to Section
16.07.

     In order to exercise the conversion privilege with respect to any interest in a Global Note,
the beneficial holder must complete, or cause to be completed, the appropriate instruction form for
conversion pursuant to the Depositary’s book-entry conversion program, deliver, or cause to be
delivered, by book-entry delivery an interest in such Global Note, furnish appropriate endorsements
and transfer documents if required by the Company or the Trustee or conversion agent, and pay the
funds, if any, required by Section 16.02(c) and any transfer taxes if required pursuant to Section
16.07.

     (b) As promptly as practicable after satisfaction of the requirements for conversion set forth
above, subject to compliance with any restrictions on transfer if shares issuable on conversion are
to be issued in a name other than that of the Noteholder (as if such transfer were a transfer of
the Note or Notes (or portion thereof) so converted), the Company shall issue and shall deliver to
such Noteholder at the office or agency maintained by the Company for such purpose pursuant to
Section 6.02, a certificate or certificates for the number of full shares of Common Stock issuable
upon the conversion of such Note or portion thereof as determined by the Company in accordance with
the provisions of this Article 16 and a check or cash in respect of any fractional interest in
respect of a share of Common Stock arising upon such conversion, calculated by the Company as
provided in Section 16.03. In case any Note of a denomination greater than $1,000 shall be
surrendered for partial conversion, and subject to Section 2.03, the Company shall execute and the
Trustee shall authenticate and deliver to the holder of the Note so surrendered, without charge to
him, a new Note or Notes in authorized denominations in an aggregate principal amount equal to the
unconverted portion of the surrendered Note.

     Each conversion shall be deemed to have been effected as to any such Note (or portion thereof)
on the date on which the requirements set forth above in this Section 16.02 have been satisfied as
to such Note (or portion thereof), and the

55

 

Person in whose name any certificate or certificates for
shares of Common Stock shall be issuable upon such conversion shall be deemed to have become on
said date the holder of record of the shares represented thereby; provided that any such surrender
on any date when the stock transfer books of the Company shall be closed shall constitute the
Person in whose name the certificates are to be issued as the record holder thereof for all
purposes on the next succeeding day on which such stock transfer books are open, but such
conversion shall be at the Conversion Rate in effect on the date upon which such Note shall be
surrendered.

     (c) Any Note or portion thereof surrendered for conversion during the period from the close of
business on the record date for any interest payment date
to the close of business on the Business Day preceding the following interest payment date
shall be accompanied by payment, in immediately available funds or other funds acceptable to the
Company, of an amount equal to the interest otherwise payable on such interest payment date on the
principal amount being converted; provided that no such payment need be made (1) if the Company has
specified a redemption date following a Designated Event that is during such period, or (2) to the
extent of any overdue interest at the time of conversion with respect to such Note. Except as
provided above in this Section 16.02, no payment or other adjustment shall be made for interest
accrued on any Note converted or for dividends on any shares issued upon the conversion of such
Note as provided in this Article 16.

     Upon the conversion of a Note, that portion of the accrued but unpaid interest, with respect
to the converted Note shall not be cancelled, extinguished or forfeited, but rather shall be deemed
to be paid in full to the holder thereof through delivery of the Common Stock (together with the
cash payment, if any, in lieu of fractional shares) in exchange for the Note being converted
pursuant to the provisions hereof; and the fair market value of such shares of Common Stock
(together with any such cash payment in lieu of fractional shares) shall be treated as issued, to
the extent thereof, first in exchange for and in satisfaction of our obligation to pay the
principal amount of the converted Note, the accrued but unpaid interest, and the balance, if any,
of such fair market value of such Common Stock (and any such cash payment) shall be treated as
issued in exchange for and in satisfaction of the right to convert the Note being converted
pursuant to the provisions hereof.

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

56

 

     Section 16.03. Cash Payments in Lieu of Fractional Shares. No fractional shares of Common
Stock or scrip certificates representing fractional shares shall be issued upon conversion of
Notes. If more than one Note shall be surrendered for conversion at one time by the same holder,
the number of full shares that shall be issuable upon conversion shall be computed on the basis of
the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted
hereby) so surrendered. If any fractional share of stock would be issuable upon the conversion of
any Note or Notes, the Company shall make an adjustment and payment therefor in cash at the current
price thereof to the holder of Notes. The current price of a share of Common Stock shall be the
Closing Sale
Price on the last Trading Day immediately preceding the day on which the Notes (or specified
portions thereof) are deemed to have been converted.

     Section 16.04. Conversion Rate. Each $1,000 principal amount of the Notes shall be
convertible into 65.1890 shares of Common Stock (herein called the “Conversion Rate”), subject to
adjustment as provided in this Article 16.

     Section 16.05. Adjustment Of Conversion Rate. The Conversion Rate shall be adjusted from time
to time by the Company as follows:

     (a) In case the Company shall hereafter pay a dividend or make a distribution to all holders
of the outstanding Common Stock in shares of Common Stock, the Conversion Rate shall be increased
so that the same shall equal the rate determined by multiplying the Conversion Rate in effect at
the opening of business on the date following the date fixed for the determination of stockholders
entitled to receive such dividend or other distribution by a fraction,

     (i) the numerator of which shall be the sum of the number of shares of Common Stock
outstanding at the close of business on the date fixed for the determination of
stockholders entitled to receive such dividend or other distribution plus the total number
of shares of Common Stock constituting such dividend or other distribution; and

     (ii) the denominator of which shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such determination,

such increase to become effective immediately after the opening of business on the day following
the date fixed for such determination. For the purpose of this clause (a), the number of shares of
Common Stock at any time outstanding shall not include shares held in the treasury of the Company.
The Company will not pay any dividend or make any distribution on shares of Common Stock held in
the treasury of the Company. If any dividend or distribution of the type described in this Section
16.05(a) is declared but not so paid or made, the Conversion Rate

57

 

shall again be adjusted to the
Conversion Rate that would then be in effect if such dividend or distribution had not been
declared.

     (b) In case the Company shall issue rights or warrants to all holders of its outstanding
shares of Common Stock entitling them (for a period expiring within forty-five (45) days after the
date fixed for determination of stockholders entitled to receive such rights or warrants) to
subscribe for or purchase shares of Common Stock at a price per share less than the Current Market
Price on the date fixed for determination of stockholders entitled to receive such rights or
warrants, the Conversion Rate shall be increased so that the same shall equal the rate
determined by multiplying the Conversion Rate in effect immediately prior to the date fixed
for determination of stockholders entitled to receive such rights or warrants by a fraction,

     (i) the numerator of which shall be the number of shares of Common Stock outstanding
on the date fixed for determination of stockholders entitled to receive such rights or
warrants plus the total number of additional shares of Common Stock offered for
subscription or purchase, and

     (ii) the denominator of which shall be the sum of the number of shares of Common
Stock outstanding at the close of business on the date fixed for determination of
stockholders entitled to receive such rights or warrants plus the number of shares that
the aggregate offering price of the total number of shares so offered would purchase at
such Current Market Price.

     Such adjustment shall be successively made whenever any such rights or warrants are issued,
and shall become effective immediately after the opening of business on the day following the date
fixed for determination of stockholders entitled to receive such rights or warrants. To the extent
that shares of Common Stock are not delivered after the expiration of such rights or warrants, the
Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the
adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of
only the number of shares of Common Stock actually delivered. If such rights or warrants are not
so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be
in effect if such date fixed for the determination of stockholders entitled to receive such rights
or warrants had not been fixed. In determining whether any rights or warrants entitle the holders
to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in
determining the aggregate offering price of such shares of Common Stock, there shall be taken into
account any consideration received by the Company for such rights or warrants and any amount
payable on exercise or conversion thereof, the value of such consideration, if other than cash, to
be determined by the Board of Directors.

58

 

     (c) In case outstanding shares of Common Stock shall be subdivided into a greater number of
shares of Common Stock, the Conversion Rate in effect at the opening of business on the day
following the day upon which such subdivision becomes effective shall be proportionately increased,
and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number
of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day
following the day upon which such combination becomes effective shall be proportionately reduced,
such increase or reduction, as the case may be, to become effective immediately after the opening
of business on the day
following the day upon which such subdivision or combination becomes effective.

     (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its
Common Stock shares of any class of capital stock of the Company or evidences of its indebtedness
or assets (including securities, but excluding any rights or warrants referred to in Section
16.05(b), and excluding any dividend or distribution (x) paid exclusively in cash or (y) referred
to in Section 16.05(a) (any of the foregoing hereinafter in this Section 16.05(d)) called the
“Securities”)), then, in each such case, the Conversion Rate shall be increased so that the same
shall be equal to the rate determined by multiplying the Conversion Rate in effect on the Record
Date with respect to such distribution by a fraction,

     (i) the numerator of which shall be the Current Market Price on such Record Date; and

     (ii) the denominator of which shall be the Current Market Price on such Record Date
less the Fair Market Value (as determined by the Board of Directors, whose determination
shall be conclusive, and described in a resolution of the Board of Directors) on the
Record Date of the portion of the Securities so distributed applicable to one share of
Common Stock,

such adjustment to become effective immediately prior to the opening of business on the day
following such Record Date; provided that if the then fair market value (as so determined) of the
portion of the Securities so distributed applicable to one share of Common Stock is equal to or
greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment,
adequate provision shall be made so that each Noteholder shall have the right to receive upon
conversion the amount of Securities such holder would have received had such holder converted each
Note on the Record Date. If such dividend or distribution is not so paid or made, the Conversion
Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such
dividend or distribution had not been declared. If the Board of Directors determines the Fair
Market Value of any distribution for purposes of this Section 16.05(d) by reference to the actual
or when issued trading

59

 

market for any securities, it must in doing so consider the prices in such
market over the same period used in computing the Current Market Price on the applicable Record
Date.

     If the dividend or distribution requiring an adjustment pursuant to this clause (d) consists
of capital stock of any class or series, or similar equity interests, of or relating to a
Subsidiary or other business unit of the Company, for purposes of making such adjustment, (i) the
Current Market Price shall be determined as of the date (the “Ex-Dividend Date”) on which
“ex-dividend
trading” commences for such distribution on the NASDAQ Global Market or such other national or
regional exchange or market on which such securities are then listed or quoted, based on the
average of the Closing Sale Prices of the Common Stock for the ten (10) Trading Days commencing on
and including the fifth Trading Day after the Ex-Dividend Date and (ii) the Fair Market Value of
such dividend or distribution shall equal the number of securities distributed in respect of each
share of Common Stock multiplied by the average of the closing sale prices of those securities
distributed for the ten (10) Trading Days commencing on and including the fifth Trading Day after
the Ex-Dividend Date.

     Rights or warrants distributed by the Company to all holders of Common Stock entitling the
holders thereof to subscribe for or purchase shares of the Company’s capital stock (either
initially or under certain circumstances), which rights or warrants, until the occurrence of a
specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of
Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of
Common Stock, shall be deemed not to have been distributed for purposes of this Section 16.05 (and
no adjustment to the Conversion Rate under this Section 16.05 will be required) until the
occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to
have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate
shall be made under this Section 16.05(d). If any such right or warrant, including any such
existing rights or warrants distributed prior to the date of this Indenture, are subject to events,
upon the occurrence of which such rights or warrants become exercisable to purchase different
securities, evidences of indebtedness or other assets, then the date of the occurrence of any and
each such event shall be deemed to be the date of distribution and record date with respect to new
rights or warrants with such rights (and a termination or expiration of the existing rights or
warrants without exercise by any of the holders thereof). In addition, in the event of any
distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event
(of the type described in the preceding sentence) with respect thereto that was counted for
purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under
this Section 16.05 was made, (1) in the case of any such rights or warrants that shall all have
been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be
readjusted upon such final redemption or repurchase to give effect to such

60

 

distribution or Trigger
Event, as the case may be, as though it were a cash distribution, equal to the per share redemption
or repurchase price received by a holder or holders of Common Stock with respect to such rights or
warrants (assuming such holder had retained such rights or warrants), made to all holders of Common
Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or
warrants that shall have expired or been terminated without exercise by any holders thereof, the
Conversion Rate shall be readjusted as if such rights and warrants had not been issued.

     For purposes of this Section 16.05(d) and Section 16.05(a) and (b), any dividend or
distribution to which this Section 16.05(d) is applicable that also includes shares of Common
Stock, or such rights or warrants to subscribe for or purchase shares of Common Stock of the type
described in Section 16.05(b) (or both), shall be deemed instead to be (1) a dividend or
distribution of the evidences of indebtedness, assets or shares of capital stock other than such
shares of Common Stock or rights or warrants (and any Conversion Rate adjustment required by this
Section 16.05(d) with respect to such dividend or distribution shall then be made) immediately
followed by (2) a dividend or distribution of such shares of Common Stock or such rights or
warrants (and any further Conversion Rate adjustment required by Sections 16.05(a) and 16.05(b)
with respect to such dividend or distribution shall then be made), except (A) the Record Date of
such dividend or distribution shall be substituted as “the date fixed for the determination of
stockholders entitled to receive such dividend or other distribution”, “the date fixed for the
determination of stockholders entitled to receive such rights or warrants” and “the date fixed for
such determination” within the meaning of Section 16.05(a) and 16.05(b) and (B) any shares of
Common Stock included in such dividend or distribution shall not be deemed “outstanding at the
close of business on the date fixed for such determination” within the meaning of Section 16.05(a).

     (e) In case the Company shall, by dividend or otherwise, distribute to all holders of its
Common Stock cash, then, in such case, the Conversion Rate shall be increased so that the same
shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to
the close of business on such Record Date by a fraction,

     (i) the numerator of which shall be the Current Market Price on such Record Date; and

     (ii) the denominator of which shall be the Current Market Price on such Record Date
less the amount of cash so distributed (and not excluded as provided above) applicable to
one share of Common Stock,

such adjustment to be effective immediately prior to the opening of business on the day following
the record date; provided that if the portion of the cash so

61

 

distributed applicable to one share of
Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of
the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the
right to receive upon conversion the amount of cash such holder would have received had such holder
converted each Note on the Record Date. If such dividend or distribution is not so paid or made,
the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect
if such dividend or distribution had not been declared. If any adjustment is required to be made
as set forth in this Section 16.05(e) as a result of a distribution that is a quarterly
dividend, such adjustment shall be based upon the amount by which such distribution exceeds the
amount of the quarterly cash dividend permitted to be excluded pursuant hereto. If an adjustment
is required to be made as set forth in this Section 16.05(e) above as a result of a distribution
that is not a quarterly dividend, such adjustment shall be based upon the full amount of the
distribution.

     (f) In case a tender or exchange offer made by the Company or any Subsidiary for all or any
portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the
expiration thereof) shall require the payment to stockholders of consideration per share of Common
Stock having a Fair Market Value (as determined by the Board of Directors, whose determination
shall be conclusive, and described in a resolution of the Board of Directors) that as of the last
time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange
offer (as it may be amended) exceeds the Closing Sale Price of a share of Common Stock on the
Trading Day next succeeding the Expiration Time, the Conversion Rate shall be increased so that the
same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior
to the Expiration Time by a fraction,

     (i) the numerator of which shall be the sum of (x) the Fair Market Value (determined
as aforesaid) of the aggregate consideration payable to stockholders based on the
acceptance (up to any maximum specified in the terms of the tender or exchange offer) of
all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted up to any such maximum, being referred to as the “Purchased
Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any
Purchased Shares) at the Expiration Time and the Closing Sale Price of a share of Common
Stock on the Trading Day next succeeding the Expiration Time, and

     (ii) the denominator of which shall be the number of shares of Common Stock
outstanding (including any tendered or exchanged shares) at the Expiration Time multiplied
by the Closing Sale Price of a share of Common Stock on the Trading Day next succeeding
the Expiration Time,

62

 

such adjustment to become effective immediately prior to the opening of business on the day
following the Expiration Time. If the Company is obligated to purchase shares pursuant to any such
tender or exchange offer, but the Company is permanently prevented by applicable law from effecting
any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted
to be the Conversion Rate that would then be in effect if such tender or exchange offer had not
been made.

     (g) In case of a tender or exchange offer made by a Person other than the Company or any
Subsidiary for an amount that increases the offeror’s
ownership of Common Stock to more than twenty-five percent (25%) of the Common Stock
outstanding and shall involve the payment by such Person of consideration per share of Common Stock
having a Fair Market Value (as determined by the Board of Directors, whose determination shall be
conclusive, and described in a resolution of the Board of Directors) that as of the last time (the
“Offer Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer
(as it shall have been amended) exceeds the Closing Price of a share of Common Stock on the Trading
Day next succeeding the Offer Expiration Time, and in which, as of the Offer Expiration Time the
Board of Directors is not recommending rejection of the offer, the Conversion Rate shall be
increased so that the same shall equal the rate determined by multiplying the Conversion Rate in
effect immediately prior to the Offer Expiration Time by a fraction

     (i) the numerator of which shall be the sum of (x) the Fair Market Value (determined
as aforesaid) of the aggregate consideration payable to stockholders based on the
acceptance (up to any maximum specified in the terms of the tender or exchange offer) of
all shares validly tendered or exchanged and not withdrawn as of the Offer Expiration Time
(the shares deemed so accepted, up to any such maximum, being referred to as the “Accepted
Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding
(less any Accepted Purchased Shares) at the Offer Expiration Time and the Closing Sale
Price of a share of Common Stock on the Trading Day next succeeding the Offer Expiration
Time, and

     (ii) the denominator of which shall be the number of shares of Common Stock
outstanding (including any tendered or exchanged shares) at the Offer Expiration Time
multiplied by the Closing Sale Price of a share of Common Stock on the Trading Day next
succeeding the Offer Expiration Time,

such adjustment to become effective immediately prior to the opening of business on the day
following the Offer Expiration Time. If such Person is obligated to purchase shares pursuant to
any such tender or exchange offer, but such Person is

63

 

permanently prevented by applicable law from
effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again
be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer
had not been made. Notwithstanding the foregoing, the adjustment described in this Section
16.05(g) shall not be made if, as of the Offer Expiration Time, the offering documents with respect
to such offer disclose a plan or intention to cause the Company to engage in any transaction
described in Article 13.

     (h) For purposes of this Section 16.05, the following terms shall have the meaning indicated:

     (i) “Current Market Price” shall mean the average of the daily Closing Sale Prices
per share of Common Stock for the ten consecutive Trading Days ending on the earlier of
such date of determination and the day before the “ex” date with respect to the issuance,
distribution, subdivision or combination requiring such computation immediately prior to
the date in question. For purpose of this clause (i), the term “ex” date, (1) when used
with respect to any issuance or distribution, means the first date on which the Common
Stock trades, regular way, on the relevant exchange or in the relevant market from which
the Closing Sale Price was obtained without the right to receive such issuance or
distribution, and (2) when used with respect to any subdivision or combination of shares
of Common Stock, means the first date on which the Common Stock trades, regular way, on
such exchange or in such market after the time at which such subdivision or combination
becomes effective.

     If another issuance, distribution, subdivision or combination to which Section 16.05 applies
occurs during the period applicable for calculating “Current Market Price” pursuant to the
definition in the preceding paragraph, “Current Market Price” shall be calculated for such period
in a manner determined by the Board of Directors to reflect the impact of such issuance,
distribution, subdivision or combination on the Closing Sale Price of the Common Stock during such
period.

     (ii) “Fair Market Value” shall mean the amount which a willing buyer would pay a
willing seller in an arm’s-length transaction.

     (iii) “Record Date” shall mean, with respect to any dividend, distribution or other
transaction or event in which the holders of Common Stock have the right to receive any
cash, securities or other property or in which the Common Stock (or other applicable
security) is exchanged for or converted into any combination of cash, securities or other
property, the date fixed for determination of stockholders entitled to receive such cash,

64

 

securities or other property (whether such date is fixed by the Board of Directors or by
statute, contract or otherwise).

     (iv) “Trading Day” shall mean (x) if the applicable security is listed or admitted
for trading on the NASDAQ Global Market or another national securities exchange, a day on
which the NASDAQ Global Market or another national securities exchange is open for
business or (y) if the applicable security is not so listed or admitted for trading, any
day other than a Saturday or Sunday or a day on which banking institutions in the State of
New York are authorized or obligated by law or executive order to close.

     (i) The Company may make such increases in the Conversion Rate, in addition to those required
by Section 16.05(a), (b), (c), (d), (e), (f) or (g) as the Board of Directors considers to be
advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase
Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or
from any event treated as such for income tax purposes.

     To the extent permitted by applicable law, the Company from time to time may increase the
Conversion Rate by any amount for any period of time if the period is at least twenty (20) days,
the increase is irrevocable during the period and the Board of Directors shall have made a
determination that such increase would be in the best interests of the Company, which determination
shall be conclusive. Whenever the Conversion Rate is increased pursuant to the preceding sentence,
the Company shall mail to holders of record of the Notes a notice of the increase at least fifteen
(15) days prior to the date the increased Conversion Rate takes effect, and such notice shall state
the increased Conversion Rate and the period during which it will be in effect.

     (j) No adjustment in the Conversion Rate shall be required unless such adjustment would
require an increase or decrease of at least one percent (1%) in such rate; provided that any
adjustments that by reason of this Section 16.05(j) are not required to be made shall be carried
forward and taken into account in any subsequent adjustment. All calculations under this Article
16 shall be made by the Company and shall be made to the nearest cent or to the nearest one-ten
thousandth (1/10,000) of a share, as the case may be. No adjustment need be made for rights to
purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest or for
any issuance of Common Stock or convertible or exchangeable securities or rights to purchase Common
Stock or convertible or exchangeable securities. To the extent the Notes become convertible into
cash, assets, property or securities (other than capital stock of the Company), no adjustment need
be made thereafter as to the cash, assets, property or such securities. Interest will not accrue
on any cash into which the Notes are convertible.

65

 

     (k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly
file with the Trustee and any conversion agent other than the Trustee an Officers’ Certificate
setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the
facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have
received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any
adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has
knowledge is still in effect. Promptly after delivery of such certificate, the Company shall
prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion
Rate and the date on which each adjustment becomes effective and shall mail such notice
of such adjustment of the Conversion Rate to the holder of each Note at his last address
appearing on the Note Register provided for in Section 2.05 of this Indenture, within twenty (20)
days after execution thereof. Failure to deliver such notice shall not affect the legality or
validity of any such adjustment.

     (l) In any case in which this Section 16.05 provides that an adjustment shall become effective
immediately after (1) a Record Date for an event, (2) the date fixed for the determination of
stockholders entitled to receive a dividend or distribution pursuant to Section 16.05(a), (3) a
date fixed for the determination of stockholders entitled to receive rights or warrants pursuant to
Section 16.05(b), (4) the Expiration Time for any tender or exchange offer pursuant to Section
16.05(f), or (5) the Offer Expiration Time for a tender or exchange offer pursuant to Section
16.05(g)(i) (each a “Determination Date”), the Company may elect to defer until the occurrence of
the applicable Adjustment Event (as hereinafter defined) (x) issuing to the holder of any Note
converted after such Determination Date and before the occurrence of such Adjustment Event, the
additional shares of Common Stock or other securities issuable upon such conversion by reason of
the adjustment required by such Adjustment Event over and above the Common Stock issuable upon such
conversion before giving effect to such adjustment and (y) paying to such holder any amount in cash
in lieu of any fraction pursuant to Section 16.03. For purposes of this Section 16.05(l), the term
“Adjustment Event” shall mean:

     (i) in any case referred to in clause (1) hereof, the occurrence of such event,

     (ii) in any case referred to in clause (2) hereof, the date any such dividend or
distribution is paid or made,

     (iii) in any case referred to in clause (3) hereof, the date of expiration of such
rights or warrants, and

66

 

     (iv) in any case referred to in clause (4) or clause (5) hereof, the date a sale or
exchange of Common Stock pursuant to such tender or exchange offer is consummated and
becomes irrevocable.

     (m) For purposes of this Section 16.05, 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.
The Company will not pay any dividend or make any distribution on shares of Common Stock held in
the treasury of the Company.

     Section 16.06. Effect Of Reclassification, Consolidation, Merger or Sale. If any of the
following events occur, namely (i) any reclassification
or change of the outstanding shares of Common Stock (other than a subdivision or combination
to which Section 16.05(c) applies), (ii) any consolidation, merger or combination of the Company
with another Person as a result of which holders of Common Stock shall be entitled to receive
stock, other securities or other property or assets (including cash) with respect to or in exchange
for such Common Stock, or (iii) any sale or conveyance of all or substantially all of the
properties and assets of the Company to any other Person as a result of which holders of Common
Stock shall be entitled to receive stock, other securities or other property or assets (including
cash) with respect to or in exchange for such Common Stock, then the Company or the successor or
purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture
(which shall comply with the Trust Indenture Act as in force at the date of execution of such
supplemental indenture) providing that each Note shall be convertible into the kind and amount of
shares of stock, other securities or other property or assets (including cash) receivable upon such
reclassification, change, consolidation, merger, combination, sale or conveyance by a holder of a
number of shares of Common Stock issuable upon conversion of such Notes (assuming, for such
purposes, a sufficient number of authorized shares of Common Stock are available to convert all
such Notes) immediately prior to such reclassification, change, consolidation, merger, combination,
sale or conveyance assuming such holder of Common Stock did not exercise his rights of election, if
any, as to the kind or amount of stock, other securities or other property or assets (including
cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or
conveyance (provided that, if the kind or amount of stock, other securities or other property or
assets (including cash) receivable upon such reclassification, change, consolidation, merger,
combination, sale or conveyance is not the same for each share of Common Stock in respect of which
such rights of election shall not have been exercised (“non-electing share”), then for the purposes
of this Section 16.06 the kind and amount of stock, other securities or other property or assets
(including cash) receivable upon such reclassification, change, consolidation, merger, combination,
sale or conveyance for each non-electing share shall be deemed to be the kind and amount so
receivable per share by a plurality of the non-electing shares). Such

67

 

supplemental indenture shall
provide for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article 16.

     The Company shall cause notice of the execution of such supplemental indenture to be mailed to
each holder of Notes, at its address appearing on the Note Register provided for in Section 2.05 of
this Indenture, within twenty (20) days after execution thereof. Failure to deliver such notice
shall not affect the legality or validity of such supplemental indenture.

     The above provisions of this Section shall similarly apply to successive reclassifications,
changes, consolidations, mergers, combinations, sales and conveyances.

     If this Section 16.06 applies to any event or occurrence, Section 16.05 shall not apply.

     Section 16.07. Taxes On Shares Issued. The issue of stock certificates on conversions of
Notes shall be made without charge to the converting Noteholder for any documentary, stamp or
similar issue or transfer tax in respect of the issue thereof. The Company shall not, however, be
required to pay any such tax which may be payable in respect of any transfer involved in the issue
and delivery of stock in any name other than that of the holder of any Note converted, and the
Company shall not be required to issue or deliver any such stock certificate unless and until the
Person or Persons requesting the issue thereof shall have paid to the Company the amount of such
tax or shall have established to the satisfaction of the Company that such tax has been paid.

     Section 16.08. Reservation of Shares, Shares to Be Fully Paid; Compliance With Governmental
Requirements; Listing of Common Stock. The Company shall provide, free from preemptive rights, out
of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock
to provide for the conversion of the Notes from time to time as such Notes are presented for
conversion.

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

     The Company covenants that all shares of Common Stock which may be issued upon conversion of
Notes will upon issue be fully paid and non-assessable

68

 

by the Company and free from all taxes,
liens and charges with respect to the issue thereof.

     The Company covenants that, if any shares of Common Stock to be provided for the purpose of
conversion of Notes hereunder require registration with or approval of any governmental authority
under any federal or state law before such shares may be validly issued upon conversion, the
Company will in good faith and as expeditiously as possible, to the extent then permitted by the
rules and interpretations of the Commission (or any successor thereto), endeavor to secure such
registration or approval, as the case may be.

     The Company further covenants that, if at any time the Common Stock shall be listed on the
NASDAQ Global Market or any other national securities exchange or automated quotation system, the
Company will, if permitted by the rules of such exchange or automated quotation system, list and
keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation
system, all Common Stock issuable upon conversion of the Note; provided that if the rules of such
exchange or automated quotation system permit the Company to defer the listing of such Common Stock
until the first conversion of the Notes into Common Stock in accordance with the provisions of this
Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Notes in
accordance with the requirements of such exchange or automated quotation system at such time.

     Section 16.09. Responsibility Of Trustee. The Trustee and any other conversion agent shall
not at any time be under any duty or responsibility to any holder of Notes to determine the
Conversion Rate or whether any facts exist which may require any adjustment of the Conversion Rate,
or with respect to the nature or extent or calculation of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture provided to be employed,
in making the same. The Trustee and any other conversion agent shall not be accountable with
respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any
securities or property, which may at any time be issued or delivered upon the conversion of any
Note; and the Trustee and any other conversion agent make no representations with respect thereto.
Neither the Trustee nor any conversion agent shall be responsible for any failure of the Company to
issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or
property or cash upon the surrender of any Note for the purpose of conversion or to comply with any
of the duties, responsibilities or covenants of the Company contained in this Article 16. Without
limiting the generality of the foregoing, neither the Trustee nor any conversion agent shall be
under any responsibility to determine the correctness of any provisions contained in any
supplemental indenture entered into pursuant to Section 16.06 relating either to the kind or amount
of shares of stock or securities or property (including cash) receivable by Noteholders upon the
conversion of

69

 

their Notes after any event referred to in such Section 16.06 or to any adjustment to
be made with respect thereto, but, subject to the provisions of Section 9.01, may accept as
conclusive evidence of the correctness of any such provisions, and shall be protected in relying
upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee
prior to the execution of any such supplemental indenture) with respect thereto.

     Section 16.10. Notice To Holders Prior To Certain Actions. In case:

     (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that
would require an adjustment in the Conversion Rate pursuant to Section 16.05; or

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

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

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

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

70

 

     Section 16.11. Stockholder Rights Plans. If the rights provided for in the Company’s Rights
Agreement dated November 9, 2001, as amended, or in any future rights plan adopted by the Company
have separated from the shares of Common Stock in accordance with the provisions of the applicable
stockholder rights agreement so that the holders of the Notes would not be entitled to receive
any rights in respect of Common Stock issuable upon conversion of the Notes, the Conversion
Rate will be adjusted as provided in Section 16.05(d).

provided further that this Section 17.07 shall not require this Indenture or the Trustee to be
qualified under the Trust Indenture Act prior to the time such qualification is in fact required
under the terms of the Trust Indenture Act, nor shall it constitute any admission or acknowledgment
by any party to the Indenture that any such qualification is required prior to the time such
qualification is in fact required under the terms of the Trust Indenture Act. If any provision
hereof limits, qualifies or conflicts with another provision hereof which is required to be
included in an indenture qualified under the Trust Indenture Act, such required provision shall
control.

     Section 17.08. No Security Interest Created. Nothing in this Indenture or in the Notes,
expressed or implied, shall be construed to constitute a security interest under the Uniform
Commercial Code or similar legislation, as now or hereafter enacted and in effect, in any
jurisdiction in which property of the Company or its subsidiaries is located.

     Section 17.09. Benefits Of Indenture. Nothing in this Indenture or in the Notes, express or
implied, shall give to any Person, other than the parties hereto, any paying agent, any
authenticating agent, any Note Registrar and their successors hereunder and the holders of Notes
any benefit or any legal or equitable right, remedy or claim under this Indenture.

     Section 17.10. Table Of Contents, Headings, Etc. The table of contents and the titles and
headings of the Articles and Sections of this Indenture have been inserted for convenience of
reference only, are not to be considered a part hereof, and shall in no way modify or restrict any

     Section 17.11. Authenticating Agent. The Trustee may appoint an authenticating agent that
shall be authorized to act on its behalf, and subject to its direction, in the authentication and
delivery of Notes in connection with the original issuance thereof and transfers and exchanges of
Notes hereunder, including under Sections 2.04, 2.05, 2.06, 2.07 and 3.05, as fully to all intents
and purposes as though the authenticating agent had been expressly authorized by this Indenture and
those Sections to authenticate and deliver Notes. For all purposes of this Indenture, the
authentication and delivery of Notes by the authenticating agent shall be deemed to be
authentication and delivery of such Notes “by the Trustee” and a certificate of authentication
executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any
requirement hereunder or in the Notes for the
Trustee’s certificate of authentication. Such authenticating agent shall at all times be a
Person eligible to serve as trustee hereunder pursuant to Section 9.09.

73

 

     Any corporation into which any authenticating agent may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, consolidation or conversion
to which any authenticating agent shall be a party, or any corporation succeeding to the corporate
trust business of any authenticating agent, shall be the successor of the authenticating agent
hereunder, if such successor corporation is otherwise eligible under this Section 17.11, without
the execution or filing of any paper or any further act on the part of the parties hereto or the
authenticating agent or such successor corporation.

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

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

     The provisions of Sections 9.02, 9.03, 9.04 and 10.03 and this Section 17.11 shall be
applicable to any authenticating agent.

     Section 17.12. Execution In Counterparts. This Indenture may be executed in any number of
counterparts, each of which shall be an original, but such counterparts shall together constitute
but one and the same instrument.

     Section 17.13. Severability. In case any provision in this Indenture or in the Notes shall be
invalid, illegal or unenforceable, then (to the extent permitted by law) the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

     The Trustee hereby accepts the trusts in this Indenture declared and provided, upon the terms
and conditions herein above set forth.

FORM OF REVERSE OF NOTE

ATHEROGENICS, INC.

41/2% CONVERTIBLE NOTE DUE 2011

     This Note is one of a duly authorized issue of Notes of the Company, designated as its 41/2%
Convertible Notes Due 2011 (herein called the “Notes”), limited in aggregate principal amount to
$100,000,000, issued and to be issued under and pursuant to an
Indenture dated as of July 11,
2007 (herein called the “Indenture”), between the Company and The Bank of New York Trust Company of
Florida N.A., as trustee (herein called the “Trustee”), to which Indenture and all indentures
supplemental thereto reference is hereby made for a description of the rights, limitations of
rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders
of the Notes.

     The Notes are issuable in fully registered form, without coupons, in denominations of $1,000
principal amount and any multiple of $1,000. Upon due presentment for registration of transfer of
this Note at the office or agency of the Company maintained for that purpose in accordance with the
terms of the Indenture, a new Note or Notes of authorized denominations for an equal aggregate
principal amount will be issued to the transferee in exchange thereof, subject to the limitations
provided in the Indenture, without charge except for any tax, assessment or other governmental
charge imposed in connection therewith.

     The Notes are not subject to redemption through the operation of any sinking fund and may not
be redeemed at the option of the Company prior to maturity.

     If a Designated Event occurs at any time prior to maturity of the Notes, this Note will be
redeemable at the option of the holder of this Note at a redemption price equal to 100% of the
principal amount hereof, together with accrued interest to (but excluding) the redemption date, as
provided in Article 3 of the Indenture.

     Subject to compliance with the provisions of the Indenture, prior to the close of business on
the final maturity date of the Notes, the holder hereof has the right, at its option, to convert
each $1,000 principal amount of this Note into 65.1890 shares (the “Conversion Rate”) of the
Company’s Common Stock, as such shares shall be constituted at the date of conversion and subject
to adjustment from time to time as provided in the Indenture.

     No adjustment in respect of interest on any Note converted or dividends on any shares issued
upon conversion of such Note will be made upon any conversion except as set forth in the next
sentence. If this Note (or portion

A-6

 

hereof) is surrendered for conversion during the period from the close of business on any
record date for the payment of interest to the close of business on the Business Day preceding the
following interest payment date, this Note (or portion hereof being converted) must be accompanied
by payment, in immediately available funds or other funds acceptable to the Company, of an amount
equal to the interest otherwise payable on such interest payment date on the principal amount being
converted; provided that no such payment shall be required (1) if the Company has specified a
redemption date following a Designated Event that is after a record date and on or prior to the
next interest payment date or (2) to the extent of any overdue interest at the time of conversion
with respect to this Note.

     No fractional shares will be issued upon any conversion, but an adjustment and payment in cash
will be made, as provided in the Indenture, in respect of any fraction of a share which would
otherwise be issuable upon the surrender of any Note or Notes for conversion.

     A Note in respect of which a holder is exercising its right to require redemption upon a
Designated Event may be converted only if such holder withdraws its Redemption Notice in accordance
with the terms of the Indenture.

     In case an Event of Default shall have occurred and be continuing, the principal of, premium,
if any, and accrued interest, on all Notes may be declared by either the Trustee or the holders of
not less than 25% in aggregate principal amount of the Notes then outstanding, and upon said
declaration shall become, due and payable, in the manner, with the effect and subject to the
conditions provided in the Indenture.

     The Indenture contains provisions permitting the Company and the Trustee, with the consent of
the holders of at least a majority in aggregate principal amount of the Notes at the time
outstanding, to execute supplemental indentures adding any provisions to or changing in any manner
or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying
in any manner the rights of the holders of the Notes, subject to the exceptions set forth in
Section 12.02 of the Indenture. Subject to the provisions of the Indenture, the holders of a
majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the
holders of all of the Notes waive any past default or Event of Default, subject to the exceptions
set forth in the Indenture. Any such consent or waiver by the holder of this Note (unless revoked
as provided in the Indenture) shall be conclusive and binding upon such holder and upon all future
holders and owners of this Note and any Notes which may be issued in exchange or substitution
hereof, irrespective of whether or not any notation thereof is made upon this Note or such other
Notes.

     No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, which is

A-7

 

absolute and unconditional, to pay the principal of and any premium and interest, on this Note
at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

     The Company, the Trustee, any authenticating agent, any paying agent, any conversion agent and
any Note Registrar may deem and treat the registered holder hereof as the absolute owner of this
Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or
other writing hereon made by anyone other than the Company or any Note Registrar) for the purpose
of receiving payment hereof, or on account hereof, for the conversion hereof and for all other
purposes, and neither the Company nor the Trustee nor any other authenticating agent nor any paying
agent nor other conversion agent nor any Note Registrar shall be affected by any notice to the
contrary. All payments made to or upon the order of such registered holder shall, to the extent of
the sum or sums paid, satisfy and discharge liability for monies payable on this Note.

     No recourse for the payment of the principal of or any premium or interest on this Note, or
for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any
obligation, covenant or agreement of the Company in the Indenture or any supplemental indenture or
in any Note, or because of the creation of any indebtedness represented thereby, shall be had
against any incorporator, stockholder, employee, agent, officer or director or subsidiary, as such,
past, present or future, of the Company or of any successor corporation, either directly or through
the Company or any successor corporation, whether by virtue of any constitution, statute or rule of
law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by
acceptance hereof and as part of the consideration for the issue hereof, expressly waived and
released.

     Terms used in this Note and defined in the Indenture are used herein as therein defined.
