Issue, Description, Execution, Registration and Exchange of Notes


 


Section 2.01. Scope of Supplemental Indenture.
This Supplemental Indenture supplements the provisions of the Base Indenture, to which provisions reference is hereby made. The
changes, modifications and supplements to the Base Indenture effected by this Supplemental Indenture shall be applicable only with
respect to, and shall only govern the terms of, the Notes, which may be issued from time to time, and shall not apply to any other
Securities that may be issued under the Base Indenture unless a supplemental indenture with respect to such other Securities specifically
incorporates such changes, modifications and supplements. For all purposes under the Base Indenture, the Notes shall constitute
a single series of Securities, and with regard to any matter requiring the consent under the Base Indenture of Holders of multiple
series of Securities voting together as a single class, the consent of Holders of the Notes voting as a separate class shall also
be required and the same threshold shall apply. The provisions of this Supplemental Indenture shall supersede any conflicting provisions
in the Base Indenture. 


 


Section 2.02. Designation and Amount.
The Notes are hereby created and authorized as a single series of Securities under the Base Indenture. The Notes shall be designated
as the “3.375% Convertible Senior Notes due 2018.” The aggregate principal amount of Notes that may be authenticated
and delivered under the Indenture is initially limited to $150,000,000, subject to Section 2.07 and except for Notes authenticated
and delivered upon registration or transfer of, or in exchange for, or in lieu of other Notes pursuant to Section 3.04, Section
3.05, Section 3.06 and Section 9.06 of the Base Indenture and
Section 8.02 and Section 9.04 of this Supplemental Indenture.


 


Section 2.03. Form of Notes. The
Notes shall be substantially in the form set forth in Exhibit A, the terms and provisions of which shall constitute, and are hereby
expressly incorporated in and made a part of the Indenture. To the extent applicable, the Company and the Trustee, by their execution
and delivery of the Indenture, expressly agree to such terms and provisions and to be bound thereby.


 


Any Global Note may be endorsed with or
have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of the Indenture
as may be required by the Note Custodian or the Depositary, or as may be required to comply with any applicable law or any regulation
thereunder or with the rules and regulations of any securities exchange or automated quotation system upon which the Notes may
be listed or traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any special limitations
or restrictions to which any particular Notes are subject.


 


Each Global Note shall represent such principal
amount of the Outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate principal
amount of Outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of Outstanding Notes represented
thereby may from time to time be increased or reduced to reflect redemptions, repurchases, conversions, transfers or exchanges
permitted hereby. Any endorsement of the Global Note to reflect the amount of any increase or decrease in the amount of Outstanding
Notes represented thereby shall be made on the Schedule of Exchanges of Notes to such Global Note by the Trustee or the Note Custodian,
at the direction of the Trustee, in such manner and upon instructions given by the Holder of such Notes in accordance with the
Indenture. Payment of principal (including the Fundamental Change Repurchase Price, if applicable) of, the Redemption Price of
(if applicable), accrued and unpaid interest on, and the consideration due upon conversion of, the Global Note shall be made to
the Holder of such Note (or, in the case of consideration due upon conversion, such Holder or its designee, as the case may be)
on the date of payment, unless a record date or other means of determining Holders of the Notes eligible to receive payment is
provided for herein.

Section 2.04. Depositary.


 


(a)           
So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, all
Notes shall be represented by one or more global Securities to which the provisions of Section 2.03 of the Base Indenture apply
(each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer
and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note, shall be effected
through the Depositary (but not the Trustee or the Note Custodian) in accordance with the Indenture (including the restrictions
on transfer set forth herein) and the Applicable Procedures of the Depositary therefor.


 


(b)           
The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints DTC to act
as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the
name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co.


 


(c)           
The fourth sentence of the fifth paragraph of Section 3.05 of the Base Indenture is hereby amended and restated in full,
with respect to the Notes, to read as follows:


 


“Definitive Securities shall
be issued and delivered by the Company (i) to each person that DTC identifies as a beneficial owner of the related Securities only
if (a) DTC has notified the Company that it is unwilling or unable to continue as depositary for the global Securities of the relevant
series and a successor depositary is not appointed within 90 calendar days or (b) DTC ceases to be registered as a clearing agency
under the Exchange Act and a successor depositary is not appointed within 90 calendar days or (ii) if an Event of Default with
respect to the Securities of any series has occurred and is continuing, to each beneficial owner who requests that its beneficial
interests in the Securities be exchanged for Securities in definitive form.”


 


(d)           
Notwithstanding anything to the contrary in the Indenture (including, without limitation, Sections 1.01, 2.03 and 3.08
of the Base Indenture) or the Notes, following the occurrence and during the continuance of an Event of Default, any beneficial
owner of a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any
other action of the Depositary or any other Person, such beneficial owner’s right to exchange its beneficial interest in
such Global Note for a Physical Note in accordance with Section 3.05 of the Base Indenture.


 






    	12



    	 



    
 


(e)           
At such time as all interests in a Global Note have been converted, canceled, repurchased or transferred, such Global Note
shall be, upon receipt thereof, canceled by the Trustee in accordance with Applicable Procedures. At any time prior to such cancellation,
if any interest in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased or transferred to a transferee
who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal
amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary
and the Note Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on the Schedule
of Exchanges of Notes to such Global Note, by the Trustee or the Note Custodian, at the direction of the Trustee, to reflect such
reduction or increase.


 


Section 2.05. Cancellation of Surrendered
Notes. The Company shall cause all Notes surrendered for payment, repurchase (including pursuant to Section 2.07, but excluding
Notes repurchased pursuant to cash-settled swaps or other derivatives), redemption, registration of transfer or exchange or conversion,
if surrendered to any Person other than the Trustee (including any of the Company’s Agents, Subsidiaries or Affiliates),
to be delivered to the Trustee for cancellation pursuant to Section 3.09 of the Base Indenture. All Notes delivered to the Trustee
shall be cancelled promptly by the Trustee. No Notes shall be authenticated in exchange for any Notes cancelled hereunder or under
the Base Indenture. For purposes of the Notes, the third to last sentence in Section 3.09 of the Base Indenture shall be deemed
to be deleted.


 


Section 2.06. Notice of Defaults. The
Company shall deliver to the Trustee, at its Corporate Trust Office, in accordance with Section 1.05 of the Base Indenture, within
30 calendar days after the occurrence thereof, an Officers’ Certificate containing notice of any events that would constitute
Defaults, the status thereof and what action the Company is taking or proposes to take in respect thereof, which notice shall make
express reference to the Company, the Indenture and the Notes.


 


Section 2.07. Additional Notes; Repurchases.
The Company may, without the consent of the Holders of the Notes and notwithstanding Section 2.01, reopen this Supplemental Indenture
and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder in an unlimited aggregate principal
amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal
income tax purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes,
the Company shall deliver to the Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’
Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 1.02 of the Base Indenture,
as the Trustee shall reasonably request. In addition, the Company may, to the extent permitted by law, and directly or indirectly
(regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by
the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements,
including by cash-settled swaps or other derivatives.

(h)           
default by the Company or any of its Subsidiaries that do not constitute Immaterial Foreign Subsidiaries with respect to
any mortgage, agreement or other instrument under which there may be outstanding, or by which there may be secured or evidenced,

and/or any such Subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness

similar official of the Company or any such Significant Subsidiary or any substantial part of its property, 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 it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts

similar official of the Company or such Significant Subsidiary or any substantial part of its property, and such involuntary case
or other proceeding shall remain undismissed and unstayed for a period of 30 consecutive calendar days.


 


Section 5.03. Acceleration of Maturity.
If an Event of Default (other than an Event of Default specified in Section 5.02(j) or Section 5.02(k)) shall occur and be

in writing to the Company (and to the Trustee if given by Holders of the Notes), may declare 100% of the principal of and accrued
and unpaid interest, if any, on all the Notes to be immediately due and payable, and upon any such declaration such principal and
accrued and unpaid interest, if any, shall be due and payable immediately. If an Event of Default specified in Section 5.02(j)
or Section 5.02(k) occurs, 100% of the principal of and accrued and unpaid interest on the Notes shall automatically become due
and payable without necessity of further action.


 


Section 5.04. Additional Interest. Notwithstanding
Section 5.03, to the extent elected by the Company, the sole remedy for an Event of Default relating to (i) the failure by the
Company to file with the Trustee pursuant to Section 314(a)(1) of the Trust Indenture Act any documents or reports that the Company
is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act or (ii) the failure to comply with
the reporting obligations under Section 4.02, shall for the first 120 calendar days after the occurrence of such an Event of Default
consist exclusively of the right to receive additional interest (“Additional Interest”) on the Notes at a rate
equal to (x) 0.25% per annum of the principal amount of the Notes Outstanding for each day during the first 60 calendar
days of such 120 calendar day period on which such Event of Default is continuing and (y) 0.50% per annum of the principal
amount of the Notes Outstanding for the remaining 60 calendar days of such 120 calendar day period on which such Event of Default
is continuing.


 


If the Company so elects to pay Additional
Interest, any such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable
on the Notes. On the 121st calendar day after such Event of Default (if the Event of Default relating to the reporting
obligations is not cured or waived prior to such 121st  calendar day), the Notes shall be subject to acceleration under
Section 5.03. The provisions of this Section 5.04 shall not affect the rights of Holders of the Notes in the event of the occurrence
of any other Event of Default. In the event the Company does not elect to pay the Additional Interest following an Event of Default
in accordance with this Section 5.04 or the Company elected to make such payment but does not pay the Additional Interest when
due, the Notes shall be immediately subject to acceleration under Section 5.03.


 






    	17



    	 



    
  


In order to elect to pay the Additional
Interest as the sole remedy during the first 120 calendar days after the occurrence of an Event of Default relating to the failure
to comply with its reporting obligations under Section 314(a)(1) of the TIA or under Section 4.02, in accordance with this Section
5.04, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning
of such 120-day period. Upon the Company’s failure to timely give such notice, the Notes shall be immediately subject to
acceleration under Section 5.03. Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office
such a notice, the Trustee may assume without inquiry that no such Additional Interest is payable.


 


Section 5.05. Rescission and Annulment.
Holders of a majority in principal amount of the Outstanding Notes, by written notice to the Company and to the Trustee, may
rescind any acceleration under Section 5.03 with respect to the Notes and its consequences if:


 


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


 


(b)          all
existing Events of Default, other than the nonpayment of the principal of and interest on the Notes that have become due solely
by such declaration of acceleration, have been cured or waived; and


 


(c)          all
amounts owing to the Trustee hereunder have been paid.


 


No such rescission and annulment shall extend
to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon.


 


In case the Trustee shall have proceeded
to enforce any right under the 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 the 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 the Notes, and the Trustee shall continue as though
no such proceeding had been taken.


 


Section
5.06. Payments of Notes on Default; Suit Therefor. Payments of the Redemption Price, the Fundamental Change Repurchase
Price, principal and interest that are not made when due shall accrue interest per annum at the then-applicable interest
rate plus one percent from the required payment date. For the avoidance of doubt, any such interest on overdue interest
shall be included, to the extent lawful, in the term “Defaulted Interest” for purposes of the Base Indenture.


 


The Company covenants that in the
case of an Event of Default pursuant to Section 5.02 (a)or Section
5.02(b), upon demand of the Trustee, the Company shall pay to the Trustee, for the benefit of the Holders of the
Notes, (i) the whole amount that then shall be due and payable on all such Notes for principal, including the Fundamental
Change Repurchase Price, if applicable, the Redemption Price, if applicable, or interest, as the case may be, with interest
upon the overdue principal and (to the extent that payment of such interest is enforceable under applicable law) upon the
overdue installments of accrued and unpaid interest determined in accordance with the first paragraph of this Section
5.06 and (ii) any amounts due the Trustee under Section 6.06 of the Base Indenture.


 






    	18



    	 



    
 


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 any
Bankruptcy Law, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, Custodian 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 5.06, 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 (including the Fundamental Change Repurchase Price, if applicable), the
Redemption Price, if applicable, and accrued and unpaid interest in respect of the Notes, and, in case of any judicial
proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee and of the Holders of the Notes allowed in such judicial 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 6.06 of the Base Indenture, and to take any other action with respect to such claims,
including participating as a member of any official committee of creditors, as it reasonably deems necessary or advisable,
unless prohibited by law or applicable regulations, and any receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, Custodian or similar official is hereby authorized by each of the Holders of the Notes to make such payments to
the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of the
Notes, 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.

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


 


All rights of action and of asserting claims
under the 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 the 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.


 


In case the Trustee shall have proceeded
to enforce any right under the 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 the Notes, and the Trustee shall, subject to any determination in such proceeding, be restored
respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders of
the Notes, and the Trustee shall continue as though no such proceeding had been instituted.


 


Section 5.07. Application of
Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 5 with respect to the Notes and
any other monies or property distributable in respect of the Company’s obligations under this Indenture following an
Event of Default specified in Section 5.02(j) or Section 5.02(k) with respect to the Company 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 (or in accordance
with Applicable Procedures, with respect to Global Notes):


 


First, to the payment of all amounts
due the Trustee and any predecessor Trustee under Section 6.06 of the
Base Indenture;


 


Second, in case the principal of
the Outstanding Notes shall not have become due and be unpaid, to the payment of accrued and unpaid interest on, and any cash due
upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion,
as the case may be, with interest (to the extent that such interest has been collected by the Trustee) upon such overdue payments
at the rate borne by the Notes at such time plus one percent, such payments to be made ratably to the Persons entitled thereto;


 






    	20



    	 



    
 


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 (including
the Redemption Price or Fundamental Change Repurchase Price and any cash due upon conversion, if applicable) then owing and unpaid
upon the Notes for principal and interest, if any, and any cash due upon conversion other amounts then payable on the Notes, with
interest on the overdue principal and, to the extent that such interest has been collected by the Trustee, upon overdue installments
of accrued and unpaid interest and any such cash due upon conversion or other amounts at the rate borne by the Notes at such time
plus one percent, 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 such interest without preference or priority of principal over interest, or
of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other
Note, ratably to the aggregate of such principal and such accrued and unpaid interest; and


 


Fourth, to the payment of the remainder,
if any, to the Company.


 


Section 5.08. Proceedings by Holders
of the Notes. No Holder of any Note shall have any right by virtue of or by availing of any provision of the Indenture to institute
any suit, action or proceeding in equity or at law upon or under or with respect to the Indenture, or for the appointment of a
receiver, trustee, liquidator, Custodian or other similar official, or for any other remedy hereunder, except to enforce the right
to receive payment of principal or interest on the Notes when due or the right to receive payment or delivery of the consideration
due upon conversion of the Notes, unless:


 


(a)          such
Holder shall have given to the Trustee written notice of an Event of Default and of the continuance thereof;


 


(b)          the
Holders of at least 25% in principal amount of the Notes then Outstanding shall have made written request upon the Trustee to institute
such action, suit or proceeding;


 


(c)          such
Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability
or expense;


 


(d)          the
Trustee shall not have complied with such request within 60 calendar days after the receipt of the request and the offer of security
or indemnity; and


 


(e)          the
Holders of a majority in principal amount of the Outstanding Notes have not given the Trustee a direction that, in the opinion
of the Trustee, is inconsistent with such request within such 60-day period pursuant to Section 5.11;


 


it being understood and intended, and being
expressly covenanted by the taker and Holder of every Note with every other taker and Holder of the Notes and the Trustee that
no one or more Holders of the Notes shall have any right in any manner whatever by virtue of or by availing of any provision of
the Indenture to affect, disturb or prejudice the rights of any other Holder of the Notes, or to obtain or seek to obtain priority
over or preference to any other such Holder of the Notes, or to enforce any right under the Indenture, except in the manner herein
provided and for the equal, ratable and common benefit of all Holders of the Notes (except as otherwise provided herein). For
the protection and enforcement of this Section 5.08, each and every Holder of the Notes and the Trustee shall be entitled to such
relief as can be given either at law or in equity.


 






    	21



    	 



    
 


Notwithstanding any other provision of the
Indenture and any provision of the Notes, the right of the Holder of any Note to receive payment or delivery, as the case may be,
of (w) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (x) accrued and unpaid interest, if
any, on, (y) if applicable, the Redemption Price of and (z) the consideration due upon conversion of, such Note, on or after
the respective due dates expressed or provided for in such Note or in the Indenture, or to institute suit for the enforcement of
any such payment or delivery, as the case may be, on or after such respective dates against the Company shall not be impaired or
affected without the consent of such Holder.


 


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


 


Section 5.09. 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 the
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 the Indenture or in aid of the exercise of any power granted in the Indenture, or to enforce any other legal
or equitable right vested in the Trustee by the Indenture or by law.


 


Section 5.10. Remedies Cumulative
and Continuing. Except as provided in the last paragraph of Section 3.06 of the Base Indenture, all powers and remedies
given by this Article 5 to the Trustee or to the Holders of the Notes shall, to the extent permitted by law, be deemed
cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of
the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements
contained in the Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any
right or power accruing upon any Default or Event of Default occurring and continuing as aforesaid shall impair any such
right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein;
and, subject to the provisions of Section 5.08, every power and remedy given by this Article 5 or by law to the Trustee or to
the Holders of the Notes may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by
the Holders of the Notes.


  


Section 5.11. Direction of Proceedings
and Waiver of Defaults by Majority of Holders of the Notes. The Holders of not less than a majority in aggregate principal
amount of the Notes at the time Outstanding shall have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee with respect to Notes; provided,
however, that Article 1 such direction shall not be in conflict with any rule of law or with the Indenture, and Article
2 the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee
may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder of the Notes or
that would involve the Trustee in personal liability. The Holders of a majority in aggregate principal amount of the Notes at
the time Outstanding may, on behalf of the Holders of all of the Notes, waive any past Default or Event of Default hereunder and
its consequences except (i) a default in the payment of principal of, or interest on, any Note when due; (ii) a failure by the
Company to convert any Notes in accordance with the provisions of the Indenture; (iii) a failure by the Company to pay the Redemption
Price on the Redemption Date in connection with a redemption by the Company or the Fundamental Change Repurchase Price on the
Fundamental Change Repurchase Date in connection with a repurchase by the Company in connection with a Fundamental Change, in
each case, in accordance with the Indenture; or (iv) a failure the Company to comply with any of the provisions of the Indenture
the non-compliance with which would require the consent of the Holder of each Outstanding Note 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 5.11, said Default or Event of Default shall for all purposes of the Notes and the Indenture be deemed to have
been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or
impair any right consequent thereon.


 






    	22



    	 



    
 


Section 5.12. Notice of Defaults.
If a Default has occurred and is continuing and is known to the Trustee, the Trustee shall mail to each Holder of the Notes, at
the address of such Holder included in the Security Register, notice of such Default within 90 calendar days after it occurs; provided
that, except in the case of a Default in the payment of the principal of, or interest on, any of the Notes or a Default in the
payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and
so long as a committee of Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in
the interests of the Holders of the Notes.


 


Section 6.01 of the Base Indenture shall
not apply to the Notes. Instead this Section 5.12 shall, with respect to the Notes, supersede in its entirety Section 6.01 of
the Base Indenture, and all references in the Base Indenture to Section 6.01 thereof and the notice provisions therein, as the
case may be, shall, with respect to the Notes, be deemed to be references to this Section 5.12 and the notice provisions set forth
in this Section 5.12, respectively.


 


Section 5.13. Undertaking to Pay Costs.
All parties to the Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed,
that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under the Indenture, or
in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit
of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable
attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of
the claims or defenses made by such party litigant; provided that the provisions of this Section 5.13 (to the extent permitted
by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder of the Notes, or group of
Holders of the Notes, holding in the aggregate more than 10% in principal amount of the Notes at the time Outstanding, or to any
suit instituted by any Holder of the Notes for the enforcement of the payment of the principal (including the Fundamental Change
Repurchase Price, if applicable) of, the Redemption Price, if applicable, of, or accrued and unpaid interest, if any, on, any
Note on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert
any Note in accordance with the provisions of Article 8.

    	25



    	 



    
 


(a)          the
resulting, surviving, or transferee person (the “Successor Company”), if not the Company, shall be a corporation
organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and the Successor
Company (if not the Company) shall expressly assume, by supplemental indenture all of the obligations of the Company under the
Notes and the Indenture; and


 


(b)          immediately

such supplemental indenture, complies with the provisions of this Article 7.


 


Article

Conversion of Notes


 


Section 8.01. Conversion Privilege.
Article 10 Subject to and upon compliance with the provisions of this Article 8, each Holder of the Notes shall have the right,
at such Holder’s option, to irrevocably convert all or any portion (if the portion to be converted is $1,000 principal amount
or an integral multiple thereof) of such Note (i) subject to satisfaction of the conditions described in Section 8.01(b), at any
time prior to the close of business on the Business Day immediately preceding November 1, 2017 under the circumstances and during
the periods set forth in Section 8.01(b), and (ii) irrespective of the conditions described in Section 8.01(b), on or after November
1, 2017 until the close of business on the second Business Day immediately preceding the Maturity Date, in each case, at an initial
conversion rate of 85.4372 shares of Common Stock (subject to adjustment as provided in Section
8.04, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to the settlement provisions
of Section 8.02, the “Conversion Obligation”).


 






    	26



    	 



    
 


(b)          Article
11 Prior to the close of business on the Business Day immediately preceding November 1, 2017, the Notes may be surrendered for
conversion during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement
Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder
of the Notes in accordance with this subsection (b)(i) and the definition of “Trading Price” in Section 1.01, for each
Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and
the Conversion Rate on each such Trading Day (the “Trading Price Condition”).


 


(A)          The
Trading Prices shall be determined by the Company based on bids, if any, received by the Bid Solicitation Agent pursuant to this
subsection (b)(i) and the definition of Trading Price set forth in this Supplemental Indenture.


 


(B)          The
Bid Solicitation Agent shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes or whether
the Trading Price Condition has been met. The Bid Solicitation Agent shall have no obligation to solicit bids from nationally recognized
securities dealers the Company selects unless the Company has requested such solicitation in writing providing the name and contact
information for the nationally recognized securities dealers the Company has chosen and the determination dates for which such
market bid quotations are to be solicited, and the Company shall have no obligation to make such request or determine the Trading
Price unless a Holder of the Notes provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount
of Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate, at
which time the Company shall instruct the Bid Solicitation Agent to solicit bids pursuant to this subsection (b)(i) and the definition
of Trading Price, and based upon such bids the Company shall determine the Trading Price per $1,000 principal amount of Notes beginning
on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater
than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate.


 


(C)          If
(x) the Company does not, when it is required to, instruct the Bid Solicitation Agent to solicit bids as described above,
(y) the Company gives such instruction to the Bid Solicitation Agent to solicit bids and the Bid Solicitation Agent fails
to obtain such bids or (z) the Bid Solicitation Agent obtains such bids and the Company fails to determine the Trading Price
based upon such bids, then, in each case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than
98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure.


 






    	27



    	 



    
 


(D)          If
the Trading Price Condition has been met on any Trading Day, the Company shall provide notice thereof to the Holders of the Notes,
the Trustee and the Conversion Agent (if other than the Trustee) in writing on such Trading Day, subject to Section 1.05 and the
last paragraph of Section 1.06 of the Base Indenture. If, at any time after the Trading Price Condition has been met, the Trading
Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the
Common Stock and the Conversion Rate for such Trading Day, the Company shall promptly provide notice thereof to the Holders of
the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing, subject to Section 1.05 and the last paragraph
of Section 1.06 of the Base Indenture.


 


(ii)          If,
prior to the close of business on the Business Day immediately preceding November 1, 2017, the Company elects to:


 


(A)          issue
to all or substantially all holders of its Common Stock any rights, options or warrants entitling them, for a period of not more
than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of Common Stock at a price
per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day
period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or


 


(B)          distribute
to all or substantially all holders of its Common Stock the Company’s assets, debt securities or rights to purchase securities
of the Company, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of
the Last Reported Sale Price of the shares of Common Stock on the Trading Day preceding the date of announcement for such distribution,


 


then, in either case, the Company shall notify all Holders of
the Notes, the Trustee and the Conversion Agent (if other than the Trustee) at least 30 Scheduled Trading Days prior to the Ex-Dividend
Date for such issuance or distribution. Once the Company has given such notice, Holders may surrender their Notes for conversion
at any time until the earlier of (1) the close of business on the Business Day immediately preceding the Ex-Dividend Date for such
issuance or distribution and (2) the Company’s announcement that such issuance or distribution will not take place, even
if the Notes are not otherwise convertible at such time.


 


(iii)          If
a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close of business
on the Business Day immediately preceding November 1, 2017, regardless of whether a Holder of the Notes has the right to require
the Company to repurchase the Notes pursuant to Section 9.02, or if the Company is a party to a consolidation, merger, binding
share exchange or similar transaction, or transfer or lease of all or substantially all of its assets, pursuant to which the Common
Stock would be converted into cash, securities or other assets, the Notes may be surrendered for conversion at any time from or
after the date that is 30 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the
Business Day after the Company gives notice of such transaction) until 35 Trading Days after the actual effective date of such
transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date.
The Company shall notify Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) (i) as promptly
as practicable following the date the Company publicly announces such transaction but in no event less than 30 Scheduled Trading
Days prior to the anticipated effective date of such transaction or (ii) if the Company does not have knowledge of such transaction
at least 30 Scheduled Trading Days prior to the anticipated effective date of such transaction, within three Business Days of the
date upon which the Company receives notice, or otherwise becomes aware, of such transaction but in no event later than the actual
effective date of such transaction.

to the close of business on the Business Day immediately preceding November 1, 2017, a Holder may surrender all or a portion of
its Notes (that is $1,000 principal amount or an integral multiple thereof) for conversion during any calendar quarter commencing
after the calendar quarter ending on June 30, 2012 (and only during such calendar quarter), if the Last Reported Sale Price of
the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending
on the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price
on each applicable Trading Day. The Company shall determine at the beginning of each calendar quarter commencing after June 30,
2012 whether the Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify the Holders of the
Notes, the Trustee and the Conversion Agent if the Notes become convertible in accordance with this clause (iv).


 


(v)          If
the Company calls the Notes for redemption pursuant to Article 10, Holders may convert their Notes at any time prior to the close
of business on the Business Day immediately preceding the Redemption Date, even if the Notes are not otherwise convertible at such
time. After that time, Holders will no longer have the right to convert their Notes on account of the Company’s delivery
of the relevant Redemption Notice, unless the Company defaults in the payment of the Redemption Price, in which case a Holder of
the Notes may convert its Notes until the Redemption Price has been paid or duly provided for.


 


Section 8.02. Conversion Procedure; Settlement
Upon Conversion.


 


(a)          Subject
to this Section 8.02, Section 8.03(b) and Section 8.07(a), upon conversion of any Note, the Company shall pay or deliver, as the
case may be, to the converting Holder of the Notes, in respect of each $1,000 principal amount of Notes being converted, cash (“Cash
Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock
in accordance with subsection (i) of this Section 8.02 (“Physical Settlement”) or a combination of cash and
shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with subsection
(i) of this Section 8.02 (“Combination Settlement”), at its election, as set forth in this Section 8.02.


 






    	29



    	 



    
 


(i)          All
conversions occurring on or after November 1, 2017 and all conversions occurring after the Company’s issuance of a Redemption
Notice with respect to the Notes and prior to the related Redemption Date shall be settled using the same Settlement Method.


 


(ii)          Except
for any conversions that occur after the Company’s issuance of a Redemption Notice with respect to the Notes but prior to
the related Redemption Date and any conversions occurring on or after November 1, 2017, the Company shall use the same Settlement
Method for all conversions occurring on the same Conversion Date, but the Company shall not have any obligation to use the same
Settlement Method with respect to conversions that occur on different Conversion Dates.


 


(iii)          Subject
to the two immediately succeeding sentences, if, in respect of any Conversion Date, the Company elects a Settlement Method in respect
of such Conversion Date, the Company, through the Trustee, shall deliver the relevant Settlement Notice to converting Holders of
the Notes no later than the close of business on the Trading Day immediately following the relevant Conversion Date. In the case
of any conversions occurring on or after the date of issuance of a Redemption Notice with respect to the Notes and prior to the
related Redemption Date, if the Company elects a Settlement Method, the Company shall notify Holders of the Notes of the relevant
Settlement Method in such Redemption Notice. In the case of any conversions on or after November 1, 2017, if the Company elects
a Settlement Method, the Company, through the Trustee, shall deliver a Settlement Notice to all Holders of the Notes no later than
November 1, 2017. If the Company does not elect a Settlement Method prior to the relevant deadline set forth in the three immediately
preceding sentences, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company
shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount
per $1,000 principal amount of Notes shall be equal to $1,000. The Settlement Notice shall specify the relevant Settlement Method
and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount.
If the Company elects Combination Settlement, but does not timely notify converting Holders of the Specified Dollar Amount, such
Specified Dollar Amount shall be deemed to be $1,000.


 


(iv)          The
cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any conversion of Notes (the “Settlement
Amount”) shall be computed by the Company as follows:


 


(A)          if
the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall
deliver to the converting Holder a number of shares of Common Stock equal to the product of Article 12 the aggregate principal
amount of Notes to be converted, divided by $1,000, and Article 13 the Conversion Rate in effect on the Conversion
Date;


 






    	30



    	 



    
 


(B)          if
the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay
to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum
of the Daily Conversion Values for each of the 20 consecutive Trading Days during the related Observation Period; and


 


(C)          if
the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination
Settlement, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal
amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 20 consecutive
Trading Days during the relevant Observation Period.


 


(v)          The
Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly
following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily
Conversion Values, as the case may be, and the amount of cash payable in lieu of any fractional share, the Company shall notify
the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values,
as the case may be, and the amount of cash payable in lieu of fractional shares of Common Stock. The Trustee and the Conversion
Agent (if other than the Trustee) shall have no responsibility for any such determination.


 


(b)          Subject
to Section 8.02(e), before any Holder of a Note shall be entitled
to convert a Note as set forth above, such Holder shall Article 14 in the case of a Global Note, comply with the procedures of
the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to
which such Holder is not entitled as set forth in Section 8.02(g) and Article 15 in the case of a Physical Note (1) complete, manually
sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile
thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal
amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates
for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such
Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office
of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds
equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 8.02(g).
The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 8 on the
Conversion Date for such conversion. No Holder may surrender Notes for conversion if such Holder has also delivered a Fundamental
Change Repurchase Notice to the Company in respect of such Notes and not validly withdrawn such Fundamental Change Repurchase Notice
in accordance with Section 9.03.


 


If more than one Note shall be surrendered
for conversion at one time by the same Holder of the Notes, the Conversion Obligation with respect to such Notes shall be computed
on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so
surrendered.


 






    	31



    	 



    
 


(c)          A
Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”)
that the Holder of the Notes has complied with the requirements set forth in subsection (b) above. The Company shall pay or deliver,
as the case may be, the consideration due (including any cash in lieu of fractional shares) in respect of the Conversion Obligation
on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on
the third Business Day immediately following the last Trading Day of the relevant Observation Period, in the case of any other
Settlement Method (subject to the provisions of Section 8.03(b) and Section 8.07(a)). If any shares of Common Stock are due to
converting Holders of the Notes, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such
Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number
of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation.


 


(d)          In
case any Note shall be surrendered for partial conversion, in $1,000 principal amount or an integral multiple thereof, the Company
shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered
a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered
Note, without payment of any service charge by the converting Holder of the Notes but, if required by the Company or Trustee, with
payment of a sum sufficient to cover any transfer tax or similar governmental charge required by law or that may be imposed in
connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the
name of the Holder of the old Notes surrendered for such conversion.


 


(e)          If
a Holder of the Notes submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer
tax due on the issuance of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares
of Common Stock to be issued in a name other than such Holder’s name, in which case such Holder shall pay that tax. The Conversion
Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than such Holder’s
name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding
sentence.


 


(f)          Upon
the conversion of an interest in a Global Note, the Trustee, or the Note Custodian at the direction of the Trustee, 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 conversion of Notes effected through any Conversion Agent other than the Trustee.


 






    	32



    	 



    
 


(g)          Upon
conversion, a Holder of the Notes shall not receive any separate cash payment for accrued and unpaid interest, if any, except as
set forth below. The Company’s payment or delivery, as the case may be, of the Settlement Amount upon conversion of any Note
shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any,
to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the
Conversion Date shall be deemed to be paid in full rather than canceled, extinguished or forfeited. Upon a conversion of Notes
into a combination of cash and shares of Common Stock, accrued and unpaid interest shall be deemed to be paid first out of the
cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular
Record Date, Holders of such Notes as of the close of business on such Regular Record Date shall receive the full amount of interest
payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion
during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest
Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that
no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity Date;
(2) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the corresponding Interest
Payment Date; (3) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on
or prior to the corresponding Interest Payment Date; or (4) to the extent of any Defaulted Interest, if any Defaulted Interest
exists at the time of conversion with respect to such Note.


 


(h)          The
Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as
the holder of record of such shares as of the close of business on the relevant Conversion Date (if the Company elects to satisfy
the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company
elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes,
such Person shall no longer be a Holder of such Notes surrendered for conversion; provided that (a) the converting
Holder shall have the right to receive the Settlement Amount due upon conversion and (b) in the case of a conversion between
a Regular Record Date and the corresponding Interest Payment Date, the Holder of record as of the close of business on such Regular
Record Date shall have the right to receive the interest payable on such Interest Payment Date, in accordance with clause (g) above.


 


(i)          The
Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of
any fractional share of Common Stock issuable upon conversion based on the Daily VWAP on the relevant Conversion Date (in the case
of Physical Settlement) or based on the Daily VWAP on the last Trading Day of the relevant Observation Period (in the case of Combination
Settlement). For each Note surrendered for conversion, if the Company has elected Combination Settlement, the full number of shares
that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the applicable
Observation Period and any fractional shares remaining after such computation shall be paid in cash.


 


Section 8.03. Adjustment to Conversion
Rate upon Conversion upon a Make-Whole Fundamental Change. Article 16 If the Effective Date of a Make-Whole Fundamental Change
occurs prior to the Maturity Date and a Holder of the Notes elects to convert its Notes in connection with such Make-Whole Fundamental
Change, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for
conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. A
conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change
if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole
Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or,
in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b)
of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change).


 






    	33



    	 



    
 


(b)          Upon
surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall, at its option, satisfy
the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section
8.02; provided, however, that if, as of the Effective Date of a Make-Whole Fundamental Change described in clause
(b) of the definition of Fundamental Change, the Reference Property is composed entirely of cash, for any conversion of Notes following
the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock
Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the
Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion
Obligation shall be determined and paid to Holders of the Notes in cash on the third Business Day following the Conversion Date.
The Company shall notify the Holders of Notes, the Trustee and the Conversion Agent in writing of the Effective Date of any Make-Whole
Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective
Date.


 


(c)          The
number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table
below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”)
and the price (the “Stock Price”) paid (or deemed to be paid) per share of Common Stock in the Make-Whole Fundamental
Change. If the holders of Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change
described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise,
the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending
on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change.


 


(d)          The
Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate
of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such
adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment
giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional
Shares set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth
in Section 8.04.


 






    	34



    	 



    
 


(e)          The
following table sets forth the number of Additional Shares to be added to the Conversion Rate per $1,000 principal amount of Notes
pursuant to this Section 8.03 for each Stock Price and Effective Date set forth below:


 


	 	 Stock Price
	
Effective Date	$8.67	$10.00	$12.50	$15.00	$17.50	$20.00	$25.00	$30.00	$40.00	$50.00	$75.00	$100.00
	April 18, 2012	29.9030	23.2177	15.7806	11.6903	9.1938	7.5407	5.5024	4.2910	2.8939	2.0993	1.0901	0.6322
	May 1, 2013	29.9030	22.5850	14.7925	10.6703	8.2495	6.6989	4.8511	3.7834	2.5675	1.8762	0.9903	0.5825
	May 1, 2014	29.9030	21.7126	13.5209	9.3982	7.0993	5.6927	4.0918	3.1984	2.1921	1.6177	0.8730	0.5244
	May 1, 2015	29.9030	20.5348	11.8719	7.8045	5.7043	4.5047	3.2254	2.5395	1.7680	1.3224	0.7369	0.4572
	May 1, 2016	29.9030	18.8812	9.6473	5.7689	4.0162	3.1274	2.2644	1.8139	1.2934	0.9863	0.5783	0.3792
	May 1, 2017	29.9030	16.6042	6.4677	3.1305	2.0458	1.6244	1.2473	1.0317	0.7659	0.6066	0.3942	0.2885
	May 1, 2018	29.9030	14.5628	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000


 


The exact Stock Prices and Effective Dates
may not be set forth in the table above, in which case:


 


(i)          if
the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in the table,
the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set
forth for the higher and lower Stock Prices and the earlier and later Effective Dates based on a 365-day year, as applicable;


 


(ii)          if
the Stock Price is greater than $100.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the
column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate;
and


 


(iii)          if
the Stock Price is less than $8.67 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column
headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate.


 


Notwithstanding the foregoing, in no event
shall the Conversion Rate per $1,000 principal amount of Notes exceed 115.3402, subject to adjustment in the same manner as the
Conversion Rate pursuant to Section 8.04.


 


(f)          Nothing
in this Section 8.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 8.04 in respect of a Make-Whole Fundamental
Change.


 


Section 8.04. Adjustment of Conversion
Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except
that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case
of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock and solely as a
result of holding the Notes, in any of the transactions described in this Section 8.04, without having to convert their Notes,
as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed
in thousands) of Notes held by such Holder of the Notes.


 






    	35



    	 



    
 


(a)          If
the Company exclusively issues shares of Common Stock as a dividend or distribution on its shares of Common Stock, or if the Company
effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula:


 





 


where,


 


	CR0	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the Effective Date of such share split or share combination, as applicable;
	 	 
	CR1	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or Effective Date;
	 	 
	OS0	=	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date; and
	 	 
	OS1	=	the number of shares of Common Stock that will be outstanding immediately after giving effect to such dividend, distribution, share split or share combination.




 


Any adjustment made under this Section 8.04(a) shall become
effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after
the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution
of the type described in this Section 8.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted,
effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that
would then be in effect if such dividend or distribution had not been declared.


 






    	36



    	 



    
 


(b)          If
the Company issues to all or substantially all holders of its shares of Common Stock any rights, options or warrants (other than
rights issued pursuant to a stockholder rights plan) entitling them, for a period of not more than 45 calendar days after the announcement
date of such issuance, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of
the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading
Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the following
formula:


 





 


where,


 


	CR0	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;
	 	 	 
	CR1	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
	 	 	 
	OS0	=	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;
	 	 	 
	X	=	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
	 	 	 
	Y	=	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.




 


Any increase made under this Section 8.04(b) shall be made successively
whenever any such rights, options or warrants are issued and shall become effective immediately after the open of business on the
Ex-Dividend Date for such issuance. To the extent that shares of Common Stock are not delivered after the expiration of such rights,
options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase
with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares
of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased
to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.


 


For purposes of this Section 8.04(b) and
Section 8.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase
shares of Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading
Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, 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, options 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.


 






    	37



    	 



    
 


(c)          If
the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or
rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common
Stock, excluding Article 17 dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 8.04(a)
or Section 8.04(b), Article 18 dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant
to Section 8.04(d), and Article 19 Spin-Offs as to which the provisions set forth below in this Section 8.04(c) shall apply (any
of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire
Capital Stock or other securities of the Company, the “Distributed Property”), then the Conversion Rate shall
be increased based on the following formula:


 





 


where,


 


	CR0	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
	 	 	 
	CR1	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
	 	 	 
	SP0	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and
	 	 	 
	FMV	=	the fair market value (as determined by the Board of Directors) of the Distributed Property with respect to each outstanding share of Common Stock on the Ex-Dividend Date for such distribution.




 


Any increase made under the portion of this
Section 8.04(c) above shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution.
If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in
effect if such distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal
to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall
receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common
Stock receive the Distributed Property, the amount and kind of Distributed Property such Holder would have received if such Holder
owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If
the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 8.04(c)
by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market
over the same period used in computing SP0.


 






    	38



    	 



    
 


With respect to an adjustment pursuant to
this Section 8.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital
Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company,
that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”),
the Conversion Rate shall be increased based on the following formula:


 





 


where,


 


	CR0	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such Spin-Off;
	 	 
	CR1	=	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such Spin-Off;
	 	 
	FMV0	=	the average of the Last Reported
    Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share
    of Common Stock (determined by reference to the definition of Last Reported Sale Price as set forth in Section 1.01 as if
    references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading
    Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and
	 	 
	MP0	=	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.




 


The adjustment to the Conversion Rate under the preceding paragraph
shall be determined on the last Trading Day of the Valuation Period but shall be given effect at the open of business on the Ex-Dividend
Date for such Spin-Off. Notwithstanding the foregoing, in respect of any conversion during the Valuation Period, references in
the portion of this Section 8.04(c) related to Spin-Offs to 10 consecutive Trading Days shall be deemed to be replaced with such
lesser number of Trading Days as have elapsed from, and including the Ex-Dividend Date of such Spin-Off to, but excluding, the
Conversion Date in determining the Conversion Rate. In addition, if the Ex-Dividend Date for the Spin-Off is less than 10 consecutive
Trading Days prior to, and including, the end of the Observation Period in respect of any conversion, references in the portion
of this Section 8.04(c) related to Spin-Offs to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion,
with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including,
the last Trading Day of such Observation Period.


 


If any such distribution that constitutes
a Spin-Off is declared but not made, and such distribution has resulted in an adjustment to the Conversion Rate, the Conversion
Rate shall be re-adjusted, effective as of the date the Board of Directors determines not to make such distribution, to be the
Conversion Rate that would then be in effect if such distribution had not been declared.

For purposes of this Section 8.04(c) (and
subject in all respects to Section 8.11), rights, options or warrants
distributed by the Company to all holders of its shares of Common Stock entitling them to subscribe for or purchase shares of the
Company’s Capital Stock, including shares of Common Stock (either initially or under certain circumstances), which rights,
options 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 the shares of Common Stock, shall be deemed not to have been distributed for purposes of this Section 8.04(c) (and no adjustment
to the Conversion Rate under this Section 8.04(c) will be required)
until the occurrence of the earliest Trigger Event, whereupon such rights, options or 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 8.04(c). If any such
right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Supplemental
Indenture, are subject to events, upon the occurrence of which such rights, options 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 Ex-Dividend Date with respect to new rights, options or warrants with such rights
(in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by
any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants,
or any Trigger Event or other event (of the type described in the immediately 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 8.04(c)
was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise
by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options
or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution,
deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption
or purchase price received by a holder or holders of shares of Common Stock with respect to such rights, options or warrants (assuming
such holder had retained such rights, options or warrants), made to all holders of shares of Common Stock as of the date of such
redemption or purchase, and (2) in the case of such rights, options 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, options and warrants had not been issued.


 


For purposes of Section 8.04(a),
Section 8.04(b) and this Section 8.04(c), if any dividend or distribution
to which this Section 8.04(c) is applicable also includes one or both of:


 


(A)          a
dividend or distribution of shares of Common Stock to which Section 8.04(a) is applicable (the “Clause A Distribution”);
or


 


(B)          a
dividend or distribution of rights, options or warrants to which Section 8.04(b) is applicable (the “Clause B Distribution”),


 


then (1) such dividend or distribution, other
than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section
8.04(c) is applicable (the “Clause C Distribution”)
and any Conversion Rate adjustment required by this Section 8.04(c) with respect to such Clause C Distribution shall then be made,
and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and
any Conversion Rate adjustment required by Section 8.04(a) and Section 8.04(b) with respect thereto shall then be made, except
that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution
shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause
A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business
on such Ex-Dividend Date or effective date” within the meaning of Section 8.04(a) or “outstanding immediately prior
to the open of business on such Ex-Dividend Date” within the meaning of Section 8.04(b).


 






    	40



    	 



    
 


(d)          If
any cash dividend or distribution is made to all or substantially all holders of the shares of Common Stock (other than dividends
or distributions made in connection with the Company’s liquidation, dissolution, or winding up), the Conversion Rate shall
be adjusted based on the following formula:


 





 


where,


 


	CR0	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;
	 	 	 
	CR1	=	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
	 	 	 
	SP0	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
	 	 	 
	C	=	the amount of cash per share of Common Stock the Company distributes to all or substantially all holders of Common Stock.




 


Any increase pursuant to this Section 8.04(d)
shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution.
If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of
Directors determines not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if
such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal
to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall
receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of Common Stock,
the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion
Rate on the Ex-Dividend Date for such cash dividend or distribution. For the avoidance of doubt, there will not be any adjustment
to the Conversion Rate under this Section 8.04(d) as a result of any distribution of Reference Property to holders of the Common
Stock in connection with any Merger Event.


 






    	41



    	 



    
 


(e)          If
the Company or any of its Subsidiaries makes a payment in respect of a tender or exchange offer for the Common Stock, to the extent
that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Last Reported
Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant
to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula:


 





 


where,


 


	CR0	=	the Conversion Rate
    in effect immediately prior to the open of business on the Trading Day next succeeding the date such tender or exchange offer
    expires (the “Expiration Date”);
	 	 	 
	CR1	=	the Conversion Rate in effect immediately after the open of business on the Trading Day next succeeding the Expiration Date;
	 	 	 
	AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;
	 	 	 
	OS0	=	the number of shares of Common Stock outstanding immediately prior to the open of business on the date such tender or exchange offer is consummated (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);
	 	 	 
	OS1	=	the number of shares of Common Stock outstanding immediately after the open of business on the date such tender or exchange offer is consummated (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and
	 	 	 
	SP1	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.




 


The adjustment to the Conversion Rate under this Section 8.04(e)
shall be determined at the close of business on the 10th Trading Day immediately following, and including, the Trading Day
next succeeding the Expiration Date but shall be given effect at the open of business on the Trading Day next succeeding the Expiration
Date. Notwithstanding the foregoing, in respect of any conversion within the 10 Trading Days immediately following, and including,
the Trading Day next succeeding any Expiration Date, references in this Section 8.04(e) with respect to 10 Trading Days shall be
deemed replaced with such lesser number of Trading Days as have elapsed between such Expiration Date and the Conversion Date in
determining the Conversion Rate. In addition, if the Trading Day next succeeding the Expiration Date is less than 10 Trading Days
prior to, and including, the end of the Observation Period in respect of any conversion, references in this Section 8.04(e)
to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion, with such lesser number of Trading
Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, and including, the last Trading
Day of such Observation Period. For the avoidance of doubt, no adjustment under this Section 8.04(e) shall be made if such adjustment
would result in a decrease in the Conversion Rate.


 


(f)          Notwithstanding
anything to the contrary in this Section 8.04, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a
Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated
as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section 8.02(h) based on
an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this
Section 8.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead,
such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate
in the related dividend, distribution or other event giving rise to such adjustment.


 






    	42



    	 



    
 


(g)          Except
as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of Common Stock or any securities
convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible
or exchangeable securities.


 


(h)          In
addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 8.04, and to the extent permitted
by applicable law and subject to the applicable rules of The New York Stock Exchange, (i) the Company may increase the Conversion
Rate of the Notes by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase
would be in the Company’s best interest and (ii) the Company may (but is not required to) increase the Conversion Rate
to avoid or diminish any income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with
a dividend or distribution of shares (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate
is increased pursuant to the preceding sentence, the Company shall mail to the Holder of each Note at its last address appearing
on the Security Register a notice of the increase at least 15 calendar 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.


 


(i)          Notwithstanding
anything to the contrary in Section 8.04, the Conversion Rate shall not be adjusted:


 


(i)          upon
the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or
interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock
under any plan;


 


(ii)          upon
the issuance of any shares of Common Stock or options or rights to purchase shares of Common Stock pursuant to any present or future
employee, director or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries;


 


(iii)          upon
the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security
not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued, subject to Section
8.11;


 


(iv)          solely
for a change in the par value of the Common Stock; or


 


(v)          for
accrued and unpaid interest, if any.


 






    	43



    	 



    
 


(j)          All
calculations and other determinations under this Article 8 shall be made by the Company and all calculations of the Conversion
Rate shall be made to the nearest one-ten thousandth (1/10,000) of a share.


 


(k)          Whenever
the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent
if not 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 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 without
inquiry 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 each Holder
of the Notes at its last address appearing on the Security Register. Failure to deliver such notice shall not affect the legality
or validity of any such adjustment.


 


(l)          For
purposes of this Section 8.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the
treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held
in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions
of shares of Common Stock.


 


Section 8.05. Adjustments of Prices.
Whenever any provision of the Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the
Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and, if applicable,
the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make
appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring
an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or Expiration Date, as the case may be, of the
event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or
the Daily Settlement Amounts are to be calculated.


 


Section 8.06. Shares to be Fully Paid.
The Company shall provide, free from preemptive rights, out of its authorized but unissued shares that are not reserved for other
purposes or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time
as such Notes are presented for conversion (assuming that at the time of computation of such number of shares, all such Notes would
be converted by a single Holder of the Notes and that Physical Settlement is applicable, and including the maximum number of Additional
Shares that could be included in the Conversion Rate for a conversion in connection with a Make-Whole Fundamental Change).


 


Section 8.07. Effect of Recapitalizations,
Reclassifications and Changes of the shares of Common Stock.


 


(a)          In
the case of:


 






    	44



    	 



    
 


(i)          any
recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination),


 


(ii)          any
consolidation, merger, combination or similar transaction involving the Company,


 


(iii)          any
sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s Subsidiaries substantially
as an entirety, or


 


(iv)          any
statutory share exchange,


 


in each case, as a result of which the shares
of Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or
any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger
Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount
of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination
thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event
would have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference
Property” meaning the kind and amount of Reference Property that a holder of one share of Common Stock would have received)
upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing
Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 6.01(c)
providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however,
that at and after the effective time of the Merger Event (A) the Company shall continue to have the right to determine the form
of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 8.02 and (B)
(I) any amount payable in cash upon conversion of the Notes in accordance with Section 8.02 shall continue to be payable in cash,
(II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance
with Section 8.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares
of Common Stock would have been entitled to receive in such Merger Event and (III) the Daily VWAP shall be calculated based on
the value of a unit of Reference Property.


 


If the Merger Event causes the Common Stock
to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part
upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed
to be (A) the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively
make such an election or (B) if no holders of the shares of Common Stock affirmatively make such an election, the types and amounts
of consideration actually received by the holders of Common Stock, and (ii) the unit of Reference Property for purposes of the
immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common
Stock. If the holders receive only cash in such Merger Event, then for all conversions that occur after the effective date of such
Merger Event (x) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount
equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section
8.03), multiplied by the price paid per share of Common Stock in such Merger Event and (y) the Company shall satisfy the
Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the Conversion Date.
The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as
soon as practicable after such determination is made.


 






    	45



    	 



    
 


Such supplemental indenture described in
the second immediately preceding paragraph shall provide for adjustments that shall be as nearly equivalent as is possible to the
adjustments provided for in this Article 8. If, in the case of any Merger Event, the Reference Property includes shares of stock,
securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing
corporation, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person
and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall
reasonably consider necessary by reason of the foregoing, including to the extent required by the Board of Directors and practicable
the provisions providing for the purchase rights set forth in Article 9. Following any Merger Event, each reference herein to a
share of Common Stock shall be deemed to refer to a Unit of Reference Property, subject to the provisions of such supplemental
indenture.


 


(b)          In
the event the Company shall execute a supplemental indenture pursuant to subsection (a) of this Section 8.07, the Company shall
promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefore, the kind or amount of cash,
securities or property or asset that will comprise the Reference Property after any such Merger Event, any adjustment to be made
with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders
of the Notes. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder of the
Notes, at its address appearing on the Security Register, within 20 Business Days after execution thereof. Failure to deliver such
notice shall not affect the legality or validity of such supplemental indenture.


 


(c)          The
Company shall not become a party to any Merger Event unless its terms are consistent with this Section 8.07. None of the foregoing
provisions shall affect the right of a Holder of the Notes to convert its Notes into cash, shares of Common Stock or a combination
of cash and shares of Common Stock, as applicable, as set forth in Section 8.01 and Section 8.02 prior to the effective date of
such Merger Event.


 


(d)          The
above provisions of this Section shall similarly apply to successive Merger Events.


 


Section 8.08. Certain Covenants.
Article 20 The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable
by the Company and free from all taxes, liens and charges with respect to the issue thereof.


 


(b)          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, to the extent then permitted by the rules and interpretations of the Commission, secure such registration or
approval, as the case may be.


 






    	46



    	 



    
 


(c)          The
Company further covenants that if at any time the shares of Common Stock shall be listed on any national securities exchange or
automated quotation system the Company will list and keep listed, so long as the shares of Common Stock shall be so listed on such
exchange or automated quotation system, any share of Common Stock issuable upon conversion of the Notes.


 


Section 8.09. 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 the Notes
to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including
any increase) 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, property or cash that 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. 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 8.07 relating either to the kind or amount
of shares of stock or securities or property (including cash) receivable by Holders of the Notes upon the conversion of their Notes
after any event referred to in such Section 8.07 or to any adjustment to be made with respect thereto, but, subject to the provisions
of Section 6.02 of the Base Indenture, may accept (without any
independent investigation) 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. Neither the Trustee nor the Conversion Agent shall be responsible for determining
whether any event contemplated by Section 8.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible
therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 8.01(b) with
respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may
conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent promptly after the occurrence
of any such event or at such other times as shall be provided for in Section 8.01(b).


 


Section 8.10. Notice to Holders of the
Notes Prior to Certain Actions. In case of any:


 


(a)          action
by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section 8.04
or Section 8.11;


 






    	47



    	 



    
 


(b)          Merger
Event or Consolidation Transaction; or


 


(c)          voluntary
or involuntary dissolution, liquidation or winding-up of the Company or any of its Subsidiaries;


 


then, in each case (unless notice of such event is otherwise
required pursuant to another provision of the Indenture, excluding for the avoidance of doubt Section 8.04(k)), the Company shall
cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be mailed to each Holder of the
Notes at its address appearing on the Security Register, as promptly as possible and at least 20 calendar days prior to the applicable
date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the
Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of shares of Common Stock
of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which
such Merger Event, Consolidation Transaction, dissolution, liquidation or winding-up is expected to become effective or occur,
and, if applicable, the date as of which it is expected that holders of shares of Common Stock of record shall be entitled to exchange
their shares of Common Stock for securities or other property deliverable upon such Merger Event, Consolidation Transaction, dissolution,
liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such
action by the Company or one of its Subsidiaries, Merger Event, Consolidation Transaction, dissolution, liquidation or winding-up.


 


Section 8.11. Shareholder Rights Plans.
If the Company has a rights plan in effect upon conversion of the Notes into Common Stock, each share of Common Stock, if any,
issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and any certificate representing
the share of Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms
of any such shareholder rights plan, as the same may be amended from time to time. If however, prior to any conversion, the rights
have separated from the shares of Common Stock in accordance with the provisions of the applicable shareholder rights plan, the
Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of
shares of Common Stock shares of Capital Stock of the Company, evidences of its indebtedness, assets, property, rights, options
or warrants to acquire its Capital Stock or other securities as provided in Section 8.04(c), subject to readjustment in the event
of the expiration, termination or redemption of such rights.

Section 9.02. Repurchase at Option
of Holders of the Notes Upon a Fundamental Change. Article 21 If a Fundamental Change occurs at any time, each Holder of the
Notes shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s
Notes, or any portion of the principal thereof that is equal to $1,000 principal amount or an integral multiple of $1,000 principal
amount, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than
20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice at a repurchase price
equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding,
the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”); provided that if
the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which
such Regular Record Date relates, then the Company shall instead pay the full amount of accrued and unpaid interest to the Holder
of record on such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount
of Notes to be repurchased pursuant to this Article 9.


 






(b)          On
or before the 20th calendar day after the occurrence of a Fundamental Change, the Company shall provide to all Holders
of the Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “Fundamental
Change Company Notice”) of the occurrence of the effective date of the Fundamental Change and of the repurchase right
at the option of the Holders of the Notes arising as a result thereof. Each Fundamental Change Company Notice shall specify:


 


(i)          the
events causing the Fundamental Change;


 


(ii)          the
date of the Fundamental Change;


 


(iii)          the
last date on which a Holder of the Notes may exercise the repurchase right pursuant to this Article 9;


 


(iv)          the
Fundamental Change Repurchase Price;


 


(v)          the
Fundamental Change Repurchase Date;


 


(vi)          the
name and address of the Paying Agent and the Conversion Agent, if applicable;


 


(vii)          if
applicable, the Conversion Rate and any adjustments to the Conversion Rate;


 


(viii)          that
the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder of the Notes may be converted
only if such Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of the Indenture; and


 


(ix)          the
procedures that Holders of the Notes must follow to require the Company to repurchase their Notes.


 






    	49



    	 



    
 


At the Company’s request, the Trustee
shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in
all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company.


 


Such notice shall be by first class mail
to the Trustee, to the Paying Agent and to each Holder of the Notes at its address shown in the Security Register (and to beneficial
owners as required by applicable law) or, in the case of Global Notes, in accordance with Applicable Procedures. Simultaneously
with providing such notice, the Company shall publish a notice containing the information set forth in the Fundamental Change Company
Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website
or through such other public medium as the Company may use at that time.


 


No failure of the Company to give the foregoing
notices and no defect therein shall limit the repurchase rights of the Holders of the Notes or affect the validity of the proceedings
for the repurchase of the Notes pursuant to this Section 9.02.


 


(c)          Repurchases
of Notes under this Section 9.02 shall be made, at the option of the Holder of the Notes thereof, upon:


 


(i)          delivery
to the Paying Agent by a Holder of the Notes of a duly completed notice (the “Fundamental Change Repurchase Notice”)
in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in
compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global Notes, in
each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date;
and


 


(ii)          delivery
of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the Fundamental Change Repurchase
Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry
transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case such delivery
being a condition to receipt by the Holder of the Notes of the Fundamental Change Repurchase Price therefor.


 


(d)          The
Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall state:


 


(i)          in
the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase;


 


(ii)          the
portion of the principal amount of the Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and


 


(iii)          that
the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and the Indenture;


 


provided, however, that if the Notes are Global
Notes, the Fundamental Change Repurchase Notice must comply with Applicable Procedures.


 






    	50



    	 



    
 


Notwithstanding anything herein to the contrary,
any Holder of the Notes delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 9.02
shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close
of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of
withdrawal to the Paying Agent in accordance with Section 9.03.


 


The Paying Agent shall promptly notify the
Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.


 


(e)          Notwithstanding
the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders of the Notes upon a Fundamental
Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to
such date (except in the case of an acceleration resulting from a default by the Company in the payment of the Fundamental Change
Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders of the Notes thereof
any Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from a default
by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry
transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been canceled, and, upon such
return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have
been withdrawn.


 


Section 9.03. Withdrawal of Fundamental
Change Repurchase Notice. A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written
notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 9.03 at any time
prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying:


 


(i)          the
principal amount of the Notes with respect to which such notice of withdrawal is being submitted;


 


(ii)          if
Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is being submitted;
and


 


(iii)          the
principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice which portion
must be in principal amounts of $1,000 or an integral multiple of $1,000;


 


provided, however, that if the Notes are Global
Notes, the notice must comply with Applicable Procedures.


 


Section 9.04. Deposit of Fundamental
Change Repurchase Price. Article 22 The Company shall deposit with the Trustee (or other Paying Agent appointed by the Company,
or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 10.03 of
the Base Indenture) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of
money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject
to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered
for repurchase (and not withdrawn prior to the close of business on the Business Day immediately preceding the Fundamental Change
Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date with respect to such Note (provided
the Holder of the Notes has satisfied the conditions in Section 9.02) and (ii) the time of book-entry transfer or the 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
9.02 by mailing checks for the amount payable to the Holders of
such Notes entitled thereto as they shall appear in the Security Register; provided, however, that payments to the
Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee
shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental
Change Repurchase Price.


 






    	51



    	 



    
 


(b)          If
by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date the Trustee (or other Paying Agent appointed by the
Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental
Change Repurchase Date then:


 


(i)          such
Notes shall cease to be Outstanding,


 


(ii)          interest
shall cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered
to the Trustee or Paying Agent), and


 


(iii)          all
other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price
and, if the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the related Interest Payment
Date, the right of the Holder of record on such Regular Record Date to receive the related interest payment).


 


(c)          Upon
surrender of a Note that is to be repurchased in part pursuant to Section 9.02, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased
portion of the Note surrendered, without payment of any service charge.


 


Section 9.05. Covenant to Comply with
Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer pursuant to a Fundamental Change Company
Notice, the Company shall, if required:


 


(a)          comply
with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable;


 


(b)          file
a Schedule TO or any other required schedule under the Exchange Act; and


 


(c)          otherwise
comply with all federal and state securities laws in connection with any offer by the Company to repurchase the Notes;


 


in each case, so as to permit the rights and
obligations under this Article 9 to be exercised in the time and in the manner specified in this Article 9.

Optional Redemption


 


Section 10.01. Applicability of Article
XI of the Base Indenture. Article XI of the Base Indenture shall not apply to the Notes. Instead the redemption provisions
set forth in this Article 10 shall, with respect to the Notes, supersede in their entirety Article XI of the Base Indenture, and
all references in the Base Indenture to Article XI thereof and the redemption provisions therein, as the case may be, shall, with
respect to the Notes, be deemed to be references to this Article 10 or the redemption provisions set forth in this Article 10,
respectively.


 


Section 10.02. Optional Redemption.
No sinking fund is provided for the Notes. If the purchase and sale agreement relating to the Company’s pending acquisition
of Walker Group Holdings LLC terminates, the Company may redeem (an “Optional Redemption”) all, but not less
than all, of the outstanding Notes for cash on a Redemption Date to occur on or prior to August 31, 2012, at a redemption price
(the “Redemption Price”) for each $1,000 principal amount of Notes to be redeemed equal to the sum of (i) $1,010,
(ii) accrued and unpaid interest on such Notes to, but excluding, the Redemption Date and (iii) 75% of the excess, if any, of the
Redemption Conversion Value over the Initial Conversion Value (unless the Redemption Date falls after a Regular Record Date but
on or prior to the immediately succeeding Interest Payment Date, in which case the Company shall pay the full amount of accrued
and unpaid interest to Holders of record of such Notes as of the close of business on such Regular Record Date, and the Redemption
Price shall not include any accrued and unpaid interest on the Notes). Following August 31, 2012, the Notes shall not be redeemable
at the Company’s option.


 


Section 10.03. Notice of Optional Redemption;
Selection of Notes.


 


(a)          In
case the Company exercises its Optional Redemption right to redeem the Notes pursuant to Section 10.02, it shall fix a date, which
must be a Business Day, for redemption (each, a “Redemption Date”), and it or, at its written request received
by the Trustee not less than 60 calendar days prior to the Redemption Date (or such shorter period of time as may be acceptable
to the Trustee), the Trustee, in the name of and at the expense of the Company, shall provide or cause to be provided by mail or
electronic delivery a notice of such Optional Redemption (a “Redemption Notice”) not less than 45 nor more than
60 calendar days prior to the Redemption Date to the Paying Agent, the Conversion Agent and each Holder of Notes so to be redeemed
at its last address as the same appears on the Security Register; provided, however, that if the Company shall give
such notice, it shall also give written notice of the Redemption Date to the Trustee.


 


(b)          The
Redemption Notice, if sent by mail or electronic delivery in the manner herein provided, shall be conclusively presumed to have
been duly given, whether or not the Holder of any Note receives such notice. In any case, failure to give such Redemption Notice
by mail or electronic delivery or any defect in the Redemption Notice to the Holder of any Note designated for redemption shall
not affect the validity of the proceedings for the redemption of any other Note.


 






    	53



    	 



    
 


(c)          Each
Redemption Notice shall specify:


 


(i)          the
Redemption Date;


 


(ii)          the
Redemption Price (or manner of calculation if not then known);


 


(iii)          that
on the Redemption Date, the Redemption Price will become due and payable upon each such Note, and that interest thereon, if any,
shall cease to accrue on and after said date;


 


(iv)          the
place or places where such Notes are to be surrendered for payment of the Redemption Price;


 


(v)          that
Holders of the Notes may surrender their Notes for conversion at any time prior to the close of business on the Business Day immediately
preceding the Redemption Date;


 


(vi)          the
procedures a converting Holder of the Notes must follow to convert its Notes and the Settlement Method and Specified Cash Amount,
if applicable;


 


(vii)          the
Conversion Rate and, if applicable, the number of Additional Shares added to the Conversion Rate in accordance with Section 8.03;
and


 


(viii)          the
CUSIP, ISIN or other similar numbers, if any, assigned to such Notes.


 


A Redemption Notice shall be irrevocable.


 


Section 10.04. Payment of Notes Called
for Redemption.


 


(a)          If
any Redemption Notice has been given in respect of the Notes in accordance with Section 10.03, the Notes shall become due and payable
on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price. On presentation
and surrender of the Notes at the place or places stated in the Redemption Notice, the Notes shall be paid and redeemed by the
Company at the applicable Redemption Price.


 


(b)          Prior
to 11:00 a.m. on the Redemption Date, the Company shall deposit with the Paying Agent or, if the Company or a Subsidiary of the
Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 10.03 of the Base Indenture an
amount of cash (in immediately available funds if deposited on the Redemption Date), sufficient to pay the Redemption Price of
all of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds by the Paying Agent, payment for the Notes
to be redeemed shall be made promptly after the later of:


 


(i)          the
Redemption Date for such Notes; and


 






    	54



    	 



    
 


(ii)          the
time of presentation of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the
manner required by this Section 10.04.


 


The Paying Agent shall, promptly after such
payment and upon written demand by the Company, return to the Company any funds in excess of the Redemption Price.


 


Section 10.05. Restrictions on Redemption.
The Company may not redeem any Notes if the principal amount of the Notes has been accelerated under Section 5.03, and such acceleration
has not been rescinded, on or prior to the Redemption Date (except in the case of an acceleration resulting from a Default by the
Company in the payment of the Redemption Price with respect to such Notes). Except in the case of an acceleration resulting from
a Default by the Company in the payment of the Redemption Price with respect to such Notes, the Paying Agent will promptly return
to the respective Holders of the Notes thereof any Physical Notes held by it during the acceleration of the Notes, or any instructions
for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been canceled,
and, upon such return or cancellation, as the case may be, the Redemption Notice with respect thereto shall be deemed to have been
withdrawn.

3.375% Convertible Senior Note due 2018


 


This Note is one of a duly authorized issue
of Securities of the Company, designated as its 3.375% Convertible Senior Notes due 2018 (the “Notes”), limited
to the aggregate principal amount of $150,000,000 all issued or to be issued under and pursuant to an Indenture dated as of April
23, 2012 (the “Base Indenture”), as amended and supplemented by the First Supplemental Indenture dated as of
April 23, 2012 (herein called the “Supplemental Indenture”; the Base Indenture, as amended and supplemented
by the Supplemental Indenture, and as it may be further amended or supplemented from time to time, the “Indenture”),
by and between the Company and Wells Fargo Bank, National Association (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. Additional Notes may be issued in an
unlimited aggregate principal amount, subject to certain conditions specified in the Indenture.


 


In case an Event of Default, as defined
in the Indenture, shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either
the Trustee or Holders of at least 25% in aggregate principal amount of Notes then Outstanding, and upon said declaration shall
become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture.


 


Subject to the terms and conditions of the
Indenture, the Company will make all payments and deliveries in respect of the Redemption Price, the Fundamental Change Repurchase
Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent
to collect such payments in respect of the Note. The Company shall pay cash amounts in money of the United States that at the time
of payment is legal tender for payment of public and private debts.


 


The Indenture contains provisions permitting
the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances,
with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time Outstanding,
evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as
described therein. It is also provided in the Indenture that, subject to certain exceptions, 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 under the Indenture and its consequences.


 


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 absolute and unconditional,
to pay the principal (including the Fundamental Change Repurchase Price, if applicable) of, the Redemption Price, if applicable,
of, and accrued and unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the respective
times, in the amounts and, if applicable, in the lawful money herein prescribed.

The Notes are issuable in registered form
without coupons in denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of the Company
referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged
for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if
required by the Company or Trustee, with payment of a sum sufficient to cover any transfer tax or similar governmental charge required
by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange
of Notes being different from the name of the Holder of the old Notes surrendered for such exchange.


 


The Notes shall be redeemable at the Company’s
option in accordance with the terms and conditions specified in the Indenture.


 


Upon the occurrence of a Fundamental Change,
the Holder has the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s
Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase

Subject to the provisions of the Indenture,
the Holder hereof has the right, at its option, during certain periods and upon the occurrence of certain conditions specified
in the Indenture, prior to the close of business on the second Business Day immediately preceding the Maturity Date, to irrevocably
convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into cash, shares of Common Stock or a combination
of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to
time as provided in the Indenture.
