any regulation thereunder or with the rules and regulations of any securities exchange or automated quotation system upon which the Debentures may be listed or traded or designated for issuance or to conform with any usage with respect thereto, or

 (d) Every Debenture that bears or is required under this Section 2.06(d) to bear either of the legends set forth in this Section 2.06(d) (together with
any Common Stock issued upon conversion of the Debentures and required to bear either of the legends set forth in Section 2.06(e), collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in
this Section 2.06(d) (including one of the legends set forth below), unless such restrictions on transfer shall be waived by written consent of the Company, and the holder of each such Restricted Security, by such holder’s acceptance thereof,
agrees to be bound by all such restrictions on transfer. As used in Section 2.06(d) and Section 2.06(e), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security. 
  
 Until the date (the “Resale Restriction Termination Date”)
that is two (2) years after the last date of original issuance of the Debentures, any certificate evidencing such Debenture (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon
conversion thereof which shall bear the legend set forth in Section 2.06(e), if applicable) shall bear a legend in substantially the following form (unless such Debentures have been transferred pursuant to a registration statement that has been
declared effective under the Securities Act and which continues to be effective at the time of such transfer, pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless
otherwise agreed by the Company in writing, with notice thereof to the Trustee):

AS AMENDED 

  

 20 







 
(THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. NONE OF THIS DEBENTURE, THE SHARES OF COMMON STOCK ISSUABLE UPON CONVERSION OF THIS DEBENTURE
OR ANY INTEREST OR PARTICIPATION HEREIN OR THEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO,
REGISTRATION. 
  
 THE HOLDER OF THIS DEBENTURE, BY ITS ACCEPTANCE
HEREOF, AGREES TO OFFER, SELL OR OTHERWISE TRANSFER SUCH DEBENTURE, PRIOR TO THE DATE (THE “RESALE RESTRICTION TERMINATION DATE”) THAT IS TWO YEARS AFTER THE LAST DATE OF ORIGINAL ISSUANCE OF THIS DEBENTURE (OR ANY PREDECESSOR OF SUCH
SECURITY) ONLY (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) FOR SO LONG AS THE DEBENTURES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A
UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHICH NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (C) PURSUANT TO A REGISTRATION STATEMENT THAT HAS
BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, OR (D) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE RIGHTS OF THE COMPANY AND THE WITHIN MENTIONED TRUSTEE PRIOR TO ANY SUCH OFFER,
SALE OR TRANSFER PURSUANT TO CLAUSE (D) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM, AND IN EACH OF THE FOREGOING CASES WHERE REGISTRATION OR TRANSFER OF THIS DEBENTURE IS
REQUIRED, A CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THE OTHER SIDE OF THIS DEBENTURE COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE TRUSTEE. THIS LEGEND WILL BE REMOVED AFTER THE RESALE RESTRICTION TERMINATION DATE UPON THE REQUEST OF THE
HOLDER AND THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATES AND/OR OTHER INFORMATION SATISFACTORY TO THE COMPANY. 
  
 Any Debenture (or security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in accordance with
their terms may, upon surrender of such Debenture for exchange to the Debenture registrar in accordance with the provisions of this Section 2.06, be exchanged for 

  

 21 







 
a new Debenture or Debentures, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.06(d).

  
 Notwithstanding any other provisions of this Indenture (other
than the provisions set forth in this Section 2.06(d)), a Global Debenture may not be transferred as a whole or in part except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of
the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary, provided that a Global Debenture may be exchanged in whole or in part for a definitive Debenture registered in the
name of any Person other than the Depositary if (x) any holder of a beneficial interest in such Global Debenture through the Depositary requests to exchange such beneficial interest for a Debenture in registered form, in accordance with customary
procedures or (y) the Company determines, in its sole discretion, not to have Debentures represented by a Global Debenture. 
  
 The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as
Depositary with respect to the Global Debenture. Initially, the Global Debenture 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. 
  
 If at any time the Depositary for a Global Debenture
notifies the Company that it is unwilling or unable to continue as Depositary for such Debenture, the Company may appoint a successor Depositary with respect to such Debenture. If a successor Depositary for such Global Debenture is not appointed by
the Company within ninety (90) days after the Company receives such notice, the Company will execute, and the Trustee, upon receipt of an Officers’ Certificate for the authentication and delivery of Debentures, will authenticate and deliver
Debentures in definitive form in an aggregate principal amount equal to the principal amount of such Global Debenture, in exchange for such Global Debenture, and upon delivery of the Global Debenture to the Trustee such Global Debenture shall be
canceled. 
  
 Definitive Debentures issued in exchange for all or
a part of the Global Debenture pursuant to this Section 2.06(d) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct
the Trustee. Upon execution and authentication, the Trustee shall deliver such definitive Debentures to the persons in whose names such definitive Debentures are so registered. 
  
 At such time as all interests in a Global Debenture have been converted, canceled, repurchased or transferred, such Global
Debenture shall be, upon 

  

 22 







 
receipt thereof, canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any
time prior to such cancellation, if any interest in a Global Debenture is exchanged for definitive Debentures, converted, canceled, repurchased or transferred to a transferee who receives definitive Debentures therefor or any definitive Debenture is
exchanged or transferred for part of such Global Debenture, the principal amount of such Global Debenture shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced
or increased, as the case may be, and an endorsement shall be made on such Global Debenture, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase. 
  
 (e) Until the Resale Restriction Termination Date, any stock certificate
representing Common Stock issued upon conversion of such Debenture shall bear a legend in substantially the following form (unless the Debenture or such Common Stock has been sold pursuant to the exemption from registration provided by Rule 144
under the Securities Act or pursuant to a registration statement that has been declared effective under the Securities Act, and which continues to be effective at the time of such transfer, or such Common Stock has been issued upon conversion of
Debentures that have been transferred pursuant to a registration statement that has been declared effective under the Securities Act or pursuant to the exemption from registration provided by Rule 144 under the Securities Act, or unless otherwise
agreed by the Company with written notice thereof to the Trustee and any transfer agent for the Common Stock): 
  
 THE COMMON STOCK OF BLACKROCK, INC. EVIDENCED HEREBY (THE “SECURITY”) HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), OR ANY STATE SECURITIES LAWS, AND MAY NOT BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT
SUBJECT TO, REGISTRATION. 
  
 THE HOLDER OF THIS SECURITY, BY ITS
ACCEPTANCE HEREOF, AGREES TO OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE DATE (THE “RESALE RESTRICTION TERMINATION DATE”) THAT IS TWO YEARS AFTER THE LAST DATE OF ORIGINAL ISSUANCE OF THE COMPANY’S 2.625% CONVERTIBLE
DEBENTURES DUE 2035 ONLY (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN
RULE 144A UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A 

  

 23 







 
QUALIFIED INSTITUTIONAL BUYER TO WHICH NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (C) PURSUANT TO A REGISTRATION STATEMENT
THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, OR (D) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE RIGHTS OF THE COMPANY PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER
PURSUANT TO CLAUSE (D) TO REQUIRE THE DELIVERY TO THE COMPANY AND THE TRANSFER AGENT FOR THE COMMON STOCK OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO IT, AND IN EACH OF THE FOREGOING CASES WHERE REGISTRATION OR
TRANSFER OF THIS SECURITY IS REQUIRED, A CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THE OTHER SIDE OF THIS SECURITY COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE COMPANY AND THE TRANSFER AGENT FOR THIS COMMON STOCK. THIS LEGEND WILL BE
REMOVED AFTER THE RESALE RESTRICTION TERMINATION DATE UPON THE REQUEST OF THE HOLDER AND THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATES AND/OR OTHER INFORMATION SATISFACTORY TO THE COMPANY. 
  
 Any such Common Stock as to which such restrictions on transfer shall have
expired in accordance with their terms may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or
certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.06(e). 
  
 (f) Any Debenture or Common Stock issued upon the conversion or exchange of a Debenture that, prior to the expiration of the holding period applicable to
sales thereof under Rule 144(k) under the Securities Act (or any successor provision), is purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or such Affiliate unless registered under the Securities Act or
resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Debentures or Common Stock, as the case may be, no longer being “restricted securities” (as defined under Rule
144). 
  
 (g) Notwithstanding any provision of Section 2.06 to the
contrary, in the event Rule 144(k) as promulgated under the Securities Act (or any successor rule) is amended to change the two-year period under Rule 144(k) (or the corresponding period under any successor rule), from and after receipt by the
Trustee of the Officers’ Certificate and Opinion of Counsel provided for in this Section 2.06(g), (i) each reference in Section 2.06(d) to “two (2) years” and in the 

  

 24 







 
restrictive legend set forth in such paragraph to “TWO YEARS” shall be deemed for all purposes hereof to be references to such changed period, (ii)
each reference in Section 2.06(e) to “two (2) years” and in the restrictive legend set forth in such paragraph to “TWO YEARS” shall be deemed for all purposes hereof to be references to such changed period and (iii) all
corresponding references in the Debentures (including the definition of Resale Restriction Termination Date) and the restrictive legends thereon shall be deemed for all purposes hereof to be references to such changed period, provided that
such changes shall not become effective if they are otherwise prohibited by, or would otherwise cause a violation of, the then-applicable federal securities laws. The provisions of this Section 2.06(g) will not be effective until such time as the
Opinion of Counsel and Officers’ Certificate have been received by the Trustee hereunder. This Section 2.06(g) shall apply to successive amendments to Rule 144(k) (or any successor rule) changing the holding period thereunder. 
  
 Section 2.07. Mutilated, Destroyed, Lost or Stolen Debentures.
In case any Debenture shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver,
a new Debenture, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Debenture, or in lieu of and in substitution for the Debenture so destroyed, lost or stolen. In every case the applicant for a
substituted Debenture shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused
by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the
destruction, loss or theft of such Debenture and of the ownership thereof. 
  
 The Trustee or such authenticating agent may authenticate any such substituted Debenture and deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable, such
authenticating agent may require. Upon the issuance of any substituted Debenture, the Company or the Trustee may require the payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in
relation thereto and any other expenses connected therewith. In case any Debenture which has matured or is about to mature or has been called for redemption or has been tendered for repurchase upon a Designated Event or has been surrendered for
repurchase on a Repurchase Date or is about to be converted into Common Stock shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Debenture, pay or authorize the payment of or convert or authorize
the conversion of the same (without surrender thereof except in the case of a mutilated Debenture), as the case may be, if the applicant for such 

  

 25 







 
payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be
required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if
applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Debenture and of the ownership thereof. 
  
 Every substitute Debenture issued pursuant to the provisions of this Section 2.07 by virtue of the fact that any Debenture
is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Debenture shall be found at any time, and shall be entitled to all the benefits of (but shall be subject
to all the limitations set forth in) this Indenture equally and proportionately with any and all other Debentures duly issued hereunder. To the extent permitted by law, all Debentures shall be held and owned upon the express condition that the
foregoing provisions are exclusive with respect to the replacement or payment or conversion or redemption or repurchase of mutilated, destroyed, lost or stolen Debentures and shall preclude any and all other rights or remedies notwithstanding any
law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their surrender. 
  
 Section 2.08. Temporary Debentures. Pending the preparation of
Debentures in certificated form, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Debentures (printed or lithographed).
Temporary Debentures shall be issuable in any authorized denomination, and substantially in the form of the Debentures in certificated form but with such omissions, insertions and variations as may be appropriate for temporary Debentures, all as may
be determined by the Company. Every such temporary Debenture shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as
the Debentures in certificated form. Without unreasonable delay the Company will execute and deliver to the Trustee or such authenticating agent Debentures in certificated form (other than in the case of Debentures in global form) and thereupon any
or all temporary Debentures (other than any Global Debenture) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 5.02 and the Trustee or such authenticating agent shall authenticate and
deliver in exchange for such temporary Debentures an equal aggregate principal amount of Debentures in certificated form. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the
temporary Debentures shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Debentures in certificated form authenticated and delivered hereunder. 
  

 26 







 Section 2.09. Cancellation of Debentures Paid, Etc. All Debentures surrendered for the
purpose of payment, repurchase, conversion, exchange or registration of transfer, shall, if surrendered to the Company or any Paying Agent or any Debenture registrar or any Conversion Agent, be surrendered to the Trustee and promptly canceled by it,
or, if surrendered to the Trustee, shall be promptly canceled by it, and no Debentures shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall destroy canceled Debentures in
accordance with its customary procedures and, after such destruction, shall deliver a certificate of such destruction to the Company, at the Company’s written request. If the Company shall acquire any of the Debentures, such acquisition shall
not operate as satisfaction of the indebtedness represented by such Debentures unless and until the same are delivered to the Trustee for cancellation. 
  
 Section 2.10. CUSIP Numbers. The Company in issuing the Debentures may use “CUSIP” numbers (if then generally in use), and, if so, the
trustee shall use “CUSIP” numbers in Company Notices as a convenience to holders of the Debentures; provided, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the
Debentures or Company Notice and that reliance may be placed only on the other identification numbers printed on the Debentures. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 
  
 ARTI CLE 3 
 REDEMPTION OF DEBENTURES 
  
 Section 3.01. Company’s Right to Redeem; Notices to Trustee. Prior to February 20, 2010, the Debentures will not be redeemable at the
Company’s option. Beginning on February 20, 2010, the Company, at its option, may redeem the Debentures for cash at any time as a whole, or from time to time in part, at a redemption price (the “Redemption Price”) equal to 100%
of the principal amount of the Debentures to be redeemed plus accrued and unpaid interest, including Contingent Interest, if any, and accrued and unpaid Liquidated Damages, if any, on the Debentures to be redeemed to (but excluding) the Redemption
Date; provided, however, that, if the Redemption Date falls after a Record Date and on or prior to the succeeding Interest Payment Date, the Redemption Price shall be equal to 100% of the principal amount of the Debentures to be
redeemed. If the Company elects to redeem Debentures, it shall notify the Trustee in writing of the Redemption Date, the principal amount of Debentures to be redeemed and the Redemption Price. 
  
 The Company shall give the notice to the Trustee provided for in this Section
3.01 not less than thirty (30) days but not more than sixty (60) days before the Redemption Date, unless the Trustee consents to a shorter period, 

  

 27 







 
accompanied by an Officers’ Certificate to the effect that such redemption will comply with the conditions herein. 
  
 Section 3.02. Selection of Debentures to Be Redeemed. If fewer
than all the Debentures are to be redeemed, the Trustee shall select the Debentures to be redeemed pro rata or by lot or by a method that complies with applicable legal and securities exchange requirements, if any, and that the Trustee considers
appropriate and in accordance with methods generally used at the time of selection by trustees in similar circumstances. The Trustee shall make the selection from outstanding Debentures not previously called for redemption. Debentures and portions
of Debentures the Trustee selects shall be in principal amounts of $1,000 or a whole multiple of $1,000. Provisions of this Indenture that apply to Debentures called for redemption also apply to portions of Debentures called for redemption. The
Trustee shall notify the Company as promptly as practicable of the Debentures or portions of Debentures to be redeemed. 
  
 Debentures and portions of Debentures that are to be redeemed are convertible, pursuant to this Article 3, by the holder thereof until the close of
business one Business Day prior to the Redemption Date. If any Debenture selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Debenture so selected, the converted portion
of such Debenture shall be deemed (so far as may be) to be from the portion selected for redemption. Debentures that have been converted during a selection of Debentures to be redeemed may be treated by the Trustee as outstanding for the purpose of
such selection. 
  
 Section 3.03. Notice of Redemption.
At least 30 days but not more than 60 days before a Redemption Date, the Company or the Trustee (provided that the Company provided the notice specified in Section 3.01 to the Trustee not less than 45 days before the Redemption Date) shall mail
a notice of redemption by first-class mail, postage prepaid, to the holders of each Debenture to be redeemed. 
  
 The notice shall identify the Debentures to be redeemed and shall state: 
  
 (1) the Redemption Date; 
  
 (2) the Redemption Price; 
  
 (3) the then existing Conversion Rate; 
  
 (4) the name and address of the Paying Agent and the Conversion Agent; 
  

 28 







 (5) that Debentures called for redemption may be converted at any time before the close of business on
the date that is one Business Day immediately prior to the Redemption Date; 
  
 (6) that holders who want to convert their Debentures must satisfy the requirements for conversion set forth in the Debentures and this Indenture; 
  
 (7) that Debentures called for redemption must be surrendered to the Paying Agent to collect the Redemption Price;

  
 (8) if fewer than all of the outstanding Debentures are to be
redeemed, the certificate numbers, if any, and principal amounts of the particular Debentures to be redeemed; and 
  
 (9) the CUSIP number(s) of the Debentures. 
  
 At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense, provided that
the Company makes such request at least three Business Days prior to the date by which such notice of redemption must be given to holders in accordance with this Section 3.03. 
  
 Section 3.04. Effect of Notice of Redemption. Once notice of redemption is given, Debentures called for
redemption become due and payable on the Redemption Date and at the Redemption Price stated in the notice except for Debentures which are converted in accordance with the terms of this Indenture. Upon surrender to the Paying Agent, such Debentures
shall be paid at the Redemption Price stated in the notice. 
  
 Section 3.05. Deposit of Redemption Price. Prior to 10:00 a.m. (New York City time) on the Redemption Date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary thereof is the Paying Agent, shall
segregate and hold in trust) money sufficient to pay the Redemption Price of all Debentures to be redeemed on that date other than Debentures or portions of Debentures called for redemption which on or prior thereto have been delivered by the
Company to the Trustee for cancellation or have been converted. Subject to receipt of funds and/or Debentures by the Paying Agent, payment for Debentures surrendered for redemption will be made promptly after the later of (x) the Redemption Date
with respect to such Debenture and (y) the time of delivery of such Debenture to the Paying Agent by the holder thereof, by mailing checks for the amount payable to the holders of such Debentures entitled thereto as they shall appear in the
Debenture 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 Paying Agent shall as promptly as practicable
return to the Company any money not required for that purpose because of conversion of Debentures pursuant to Section 15.01. If such money is 

  

 29 







 
then held by the Company in trust and is not required for such purpose it shall be discharged from such trust. 
  
 If the Trustee (or other Paying Agent appointed by the Company) holds money
sufficient to redeem on the Redemption Date all the Debentures or portions thereof that are to be redeemed as of the Redemption Date, then on and after the Business Day following the Redemption Date (i) such Debentures will cease to be outstanding,
(ii) interest, including Contingent Interest, if any, and Liquidated Damages, if any, will cease to accrue on such Debentures, and (iii) all other rights of the holders of such Debentures will terminate, whether or not book-entry transfer of the
Debentures has been made or the Debentures have been delivered to the Trustee or Paying Agent, other than the right to receive the Redemption Price upon delivery of the Debentures. 
  
 Section 3.06. Debentures Redeemed in Part. Upon surrender of a Debenture that is redeemed in part, the Company
shall execute and the Trustee shall authenticate and deliver to the holder a new Debenture in an authorized denomination equal in principal amount to the unredeemed portion of the Debenture surrendered. In the event of any redemption in part, the
Company will not be required to (i) issue, register the transfer of or exchange any Debenture during a period beginning at the opening of business 15 days before any selection of Debentures for redemption and ending at the close of business on the
earliest date on which the relevant notice of redemption is deemed to have been given to all holders of Debentures to be so redeemed, or (ii) register the transfer of or exchange any Debenture so selected for redemption, in whole or in part, except
the unredeemed portion of any Debenture being redeemed in part. 
  
 Section 3.07. No Redemption Upon Acceleration. Notwithstanding the foregoing, the Company may not redeem the Debentures if it failed to pay any interest, including Contingent Interest, if any, and Liquidated Damages, if any, and such
failure to pay is continuing, or if the principal amount of the Debentures has been accelerated, and such acceleration has not been rescinded, on or prior to such Redemption Date.  
  
 ARTICLE 4 
 CONTINGENT INTEREST 
  
 Section 4.01. Contingent Interest. Beginning with the six-month interest period commencing February 15, 2010, the Company will pay contingent interest to the Debentureholders during a six month interest period if the Trading
Price for each $1,000 principal amount of Debentures for each of the ten Trading Days immediately preceding the first day of the applicable six-month interest period equals or exceeds $1,200. During any six-month interest period when contingent
interest is payable, the contingent interest payable on each $1,000 

  

 30 







 
principal amount of Debentures shall equal 0.25% of the average Trading Price per $1,000 principal amount of Debentures during the ten Trading Days
immediately preceding the first day of applicable six-month interest period. 
  
 The Trustee’s sole responsibility pursuant to this Section 4.01 hereof shall be to obtain the Trading Price of the Debentures for each of the ten Trading Days immediately preceding the first day of the applicable
six-month interest period and to provide such information to the Company. The Company shall determine whether holders are entitled to receive Contingent Interest, and if so, provide notice pursuant to Section 4.03. Notwithstanding any term contained
in this Indenture or any other document to the contrary, the Trustee shall have no responsibilities, duties or obligations for or with respect to (i) determining whether the Company must pay Contingent Interest or (ii) determining the amount of
Contingent Interest, if any, payable by the Company. 
  
 Section
4.02. Payment of Contingent Interest. Contingent Interest for any six-month interest period shall be paid on the applicable interest payment date to the Person in whose name any Debenture (or its Predecessor Debenture) is registered on the
Debenture Register at the corresponding Record Date. Contingent Interest due under this Article 4 shall be treated for all purposes of this Indenture like any other interest accruing on the Debentures. 
  
 Section 4.03. Contingent Interest Notification. By the first Business
Day of a six-month interest period during which Contingent Interest will be paid, the Company will disseminate a press release through Dow Jones & Company, Inc. or Bloomberg Business News stating that Contingent Interest will be paid on the
Debentures and identifying the six-month interest period (or publish the information on its website or through such other public medium it may use at that time). 
  
 ARTICLE 5 
 PARTICULAR COVENANTS OF THE COMPANY 
  
 Section 5.01. Payment of Principal, Premium, Interest and Liquidated Damages. The Company covenants and agrees that it will
duly and punctually pay or cause to be paid the principal of and premium, if any (including the redemption price upon redemption pursuant to Article 3), accrued and unpaid interest, including Contingent Interest, if any, and Liquidated Damages, if
any, on each of the Debentures at the places, at the respective times and in the manner provided herein and in the Debentures. Each installment of accrued and unpaid interest, including Contingent Interest, if any, and Liquidated Damages, if any, on
the Debentures due on any Payment Date (as defined in the Registration Rights Agreement) may be paid by mailing checks for the amount payable to or upon the written order of the Debentureholders entitled thereto as they shall appear on the registry
books of the Company, provided that, with respect to any Debentureholder with an aggregate principal amount equal to or in excess of 

  

 31 







 
$2,000,000, at the request of such holder in writing to the Company, accrued and unpaid interest, including Contingent Interest, if any, and Liquidated
Damages, if any, on such holder’s Debentures shall be paid by wire transfer in immediately available funds in accordance with the wire transfer instructions supplied by such holder from time to time to the Trustee and Paying Agent (if different
from Trustee) at least two days prior to the applicable record date; provided further that payment of accrued and unpaid interest, including Contingent Interest, if any, and Liquidated Damages, if any, made to the Depositary shall be paid by
wire transfer in immediately available funds in accordance with such wire transfer instructions and other procedures provided by the Depositary from time to time. 
  
 Section 5.02. Maintenance of Office or Agency. The Company will maintain in the Borough of Manhattan, The City of New
York, an office or agency where the Debentures may be surrendered for registration of transfer or exchange or for presentation for payment, redemptions or repurchase (“Paying Agent”) or for conversion (“Conversion
Agent”) and where notices and demands to or upon the Company in respect of the Debentures and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such
office or agency not designated or appointed by the Trustee. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices

The Company may also from time to time designate one or more other offices or agencies where the Debentures may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The
City of New York, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms Paying Agent and Conversion Agent
include any such additional or other offices or agencies, as applicable. 
  
 The Company hereby initially designates the Trustee as the Paying Agent, Debenture registrar, Custodian and Conversion Agent and the Corporate Trust Office and the office of agency of the Trustee in the Borough of
Manhattan shall be considered as one such office or agency of the Company for each of the aforesaid purposes.

third paragraph of Section 8.11.

promptly notify the Trustee of any failure to take such action, provided that if such deposit is made on the due date, such deposit must be received by the Paying Agent by 10:00 a.m., New York City time, on such date. 
  
 (b) If the Company shall act as its own Paying Agent, it will, on or before

all to the extent required from time to time to enable such holder or beneficial holder to sell its Debentures or Common Stock without registration under the Securities Act within the limitation of the exemption provided by Rule 144A, as such rule
may be amended from time to time. Upon the written request of any holder or any beneficial holder of the Debentures or such Common Stock, the Company will deliver to such holder a written statement as to whether it has complied with such

permit the execution of every such power as though no such law had been enacted. 
  
 Section 5.08. Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31,
2005) an Officers’ Certificate stating whether or not to the best of their knowledge the signers know of any default or Event of Default that occurred during such period. If they do, such Officers’ Certificate shall describe the default or
Event of Default and its status.

 (j) acceleration of Indebtedness of the Company that, in the aggregate, is equal to or exceeds
$25,000,000 and such Indebtedness is not discharged, or such acceleration is not rescinded or annulled, within a period of thirty (30) days after the date on which written notice of such failure, requiring the Company to remedy the same, shall have
been given to the Company by the Trustee, or to the Company and a Responsible Officer of the Trustee by the holders of at least 25% in aggregate principal amount of Debentures at the time outstanding, determined in accordance with Section 9.04.

  
 In case one or more Events of Default shall have occurred and
be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 7.01(g) or Section 7.01(h) with respect to the Company), unless the principal of all of the Debentures shall have
already become due and payable, either the Trustee or the holders of not less than 25% in aggregate principal amount of the Debentures then outstanding determined in accordance with Section 9.04, by notice in writing to the Company (and to the

payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Debentures contained to the contrary notwithstanding. If an Event of Default specified in Section

interest, including Contingent Interest, if any, and accrued and unpaid Liquidated Damages, if any, (to the extent that payment of such interest is enforceable under applicable law) and on such principal and premium, if any, at the rate of 3.625%
per year) and amounts due to the Trustee pursuant to Section 8.06, and if any and all defaults under this Indenture, other than the nonpayment of principal of and premium, if any, and accrued and unpaid interest, including Contingent Interest, if
any, and accrued and unpaid Liquidated Damages, if any, on Debentures that shall 

  

 39 







 
have become due by acceleration, shall have been cured or waived pursuant to Section 7.07, then and in every such case the holders of a majority in aggregate
principal amount of the Debentures then outstanding, by written notice to the Company and to the Trustee, may waive all defaults or Events of Default with respect to the Debentures and rescind and annul such declaration and its consequences; but no
such waiver or rescission and annulment shall extend to or shall affect any subsequent default or Event of Default, or shall impair any right consequent thereon. The Company shall notify the Responsible Officer of the Trustee, promptly upon becoming
aware thereof, of any Event of Default by delivering to the Trustee a statement specifying such Event of Default. 
  
 In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because
of such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Debentureholders, 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 Debentureholders, and the Trustee shall continue as though no such proceeding had been instituted.

  
 Section 7.02. Payments of Debentures on Default; Suit
Therefor. In the event that the Trustee or the holders of not less than twenty-five percent (25%) in aggregate principal amount of the Debentures then outstanding hereunder have declared the principal of and premium, if any, on all
Debentures (including accrued and unpaid interest, including Contingent Interest, if any, and accrued and unpaid Liquidated Damages, if any) to be due and payable immediately in accordance with Section 7.01, and the Company shall have failed
forthwith to pay such amounts, 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 (including
such further amounts as shall be sufficient to cover the reasonable costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel, and any expenses or liabilities incurred by the Trustee
hereunder other than through its negligence or bad faith), and may prosecute any such action or proceeding to judgment or final degree, and may enforce any such judgment or final decree against the Company or any other obligor on the Debentures and
collect in the manner provided by law out of the property of the Company or any other obligor on the Debentures wherever situated the monies adjudged or decreed to be payable. 
  
 In the case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other
obligor on the Debentures under title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, 

  

 40 







 
sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such
other obligor, or in the case of any other judicial proceedings relative to the Company or such other obligor upon the Debentures, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the
principal of the Debentures 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 7.02, shall be entitled and
empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal premium, if any, and accrued and unpaid interest, including Contingent Interest, if any, and accrued and unpaid
Liquidated Damages, if any, in respect of the Debentures, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Debentureholders allowed in such judicial proceedings relative to the Company or any
other obligor on the Debentures, 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 8.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Debentureholders to make such payments to the Trustee, as
administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Debentureholders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements,
including agents and counsel fees, and including any other amounts due to the Trustee under Section 8.06 hereof, 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 Debentures 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 Debentureholder any plan of reorganization, arrangement, adjustment or composition affecting the Debentureholder or the rights of any Debentureholder thereof, or to authorize the Trustee to vote in respect of the claim of any Debentureholder in
any such proceeding. 
  
 All rights of action and of asserting
claims under this Indenture, or under any of the Debentures, may be enforced by the Trustee without the possession of 

  

 41 







 
any of the Debentures, 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 Debentures. 
  
 In any
proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the holders of the Debentures, and it shall
not be necessary to make any holders of the Debentures parties to any such proceedings. 
  
 Section 7.03. Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 7 with respect to the Debentures 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 Debentures, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 
  
 First, to the payment of all amounts due the Trustee under Section 8.06;

  
 Second, in case the principal of the outstanding Notes shall
not have become due and be unpaid, to the payment of interest on the Notes in default in the order of the maturity of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the
overdue installments of interest at the rate borne by the Notes, such payments to be made ratably to the Persons entitled thereto; 
  
 Third, in case the principal of the outstanding Debentures shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole
amount then owing and unpaid upon the Debentures for principal and premium, if any, and interest, with interest on the overdue principal and premium, if any, and (to the extent that such interest has been collected by the Trustee) upon overdue
installments of interest at the rate borne by the Debentures, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Debentures, then to the payment of such principal and premium, if any, and
interest without preference or priority of principal and premium, if any, over interest, or of interest over principal and premium, if any, or of any installment of interest over any other installment of interest, or of any Debenture over any other
Debenture, ratably to the aggregate of such principal and premium, if any, and accrued and unpaid interest; and 
  
 Fourth, to the payment of the remainder, if any, to the Company or any other Person lawfully entitled thereto. 
  

 42 







 Section 7.04. Proceedings by Debentureholders. No holder of any Debenture shall have any
right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator,
custodian or other similar official, or for any other remedy hereunder, unless such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, and unless also the
holders of not less than 25% in aggregate principal amount of the Debentures then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered
to the Trustee such indemnity it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for sixty (60) days after its receipt of such notice, request and offer of indemnity, shall have neglected or
refused to institute any such action, suit or proceeding and no direction inconsistent with such written request shall have been given to the Trustee by the Debentureholders pursuant to Section 7.07; it being understood and intended, and being
expressly covenanted by the taker and holder of every Debenture with every other taker and holder and the Trustee, that no one or more Debentureholders shall have any right in any manner whatever by virtue of or by availing of any provision of this
Indenture to affect, disturb or prejudice the rights of any other Debentureholder, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein
provided and for the equal, ratable and common benefit of all Debentureholders (except as otherwise provided herein). For the protection and enforcement of this Section 7.04, each and every Debentureholder and the Trustee shall be entitled to such
relief as can be given either at law or in equity. 
  
 Notwithstanding any other provision of this Indenture and any provision of any Debenture, the right of any Debentureholder to receive payment of the principal of and premium, if any (including the redemption price upon redemption pursuant
to Article 3), and accrued and unpaid interest, including Contingent Interest, and accrued and unpaid Liquidated Damages, if any, on such Debenture, on or after the respective due dates expressed in such Debenture or in the notice of redemption, or
to institute suit for the enforcement of any such payment on or after such respective dates against the Company shall not be impaired or affected without the consent of such Debentureholder. 
  
 Anything in this Indenture or the Debentures to the contrary notwithstanding,
the holder of any Debenture, without the consent of either the Trustee or the holder of any other Debenture, in his own behalf and for his own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, his rights of
conversion as provided herein. 
  

 43 







 Section 7.05. Proceedings by Trustee. In case of an Event of Default the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the
Trustee by this Indenture or by law. 
  
 Section 7.06. Remedies
Cumulative and Continuing. Except as provided in the last paragraph of Section 2.07, all powers and remedies given by this Article 7 to the Trustee or to the Debentureholders 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 Debentures, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in
this Indenture, and no delay or omission of the Trustee or of any holder of any of the Debentures to exercise any right or power accruing upon any default or Event of Default shall impair any such right or power, or shall be construed to be a waiver
of any such default or any acquiescence therein; and, subject to the provisions of Section 7.04, every power and remedy given by this Article 7 or by law to the Trustee or to the Debentureholders may be exercised from time to time, and as often as
shall be deemed expedient, by the Trustee or by the Debentureholders. 
  
 Section 7.07. Direction of Proceedings and Waiver of Defaults by Majority of Debentureholders. The holders of a majority in aggregate principal amount of the Debentures at the time outstanding determined in accordance with
Section 9.04 shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to Debentures; provided,
however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The holders of a
majority in aggregate principal amount of the Debentures at the time outstanding determined in accordance with Section 9.04 may on behalf of the holders of all of the Debentures waive any past default or Event of Default hereunder and its
consequences except (i) a default in the payment of premium, accrued and unpaid interest, including Contingent Interest, if any, or accrued and unpaid Liquidated Damages, if any, on, or the principal of, the Debentures when due which has not been
cured pursuant to the provisions of Section 7.01, (ii) a failure by the Company to convert any Debentures into Common Stock or (iii) a default in respect of a covenant or provisions hereof which under Article 11 cannot be modified or amended without
the consent of the holders of all Debentures then outstanding. Upon any such waiver the Company, the Trustee and the holders of the Debentures shall be restored to their former positions and rights hereunder; 

  

 44 







 
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 7.07, said default or Event of Default shall for all purposes of the Debentures and this Indenture be deemed to have been cured and to be not continuing; but no such waiver
shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. 
  
 Section 7.08. Notice of Defaults. The Trustee shall, within ninety (90) days after the occurrence of a default of which a Responsible
Officer has actual knowledge, mail to all Debentureholders as the names and addresses of such holders appear upon the Debenture register, notice of all defaults known to a Responsible Officer, unless such defaults shall have been cured or waived
before the giving of such notice; and provided that, except in the case of default in the payment of the principal of, or premium, if any, accrued and unpaid interest, including Contingent Interest, if any, or accrued and unpaid Liquidated Damages,
if any, on any of the Debentures, including without limiting the generality of the foregoing any default in the payment of any Repurchase Price or Designated Event Repurchase Price, then in any such event the Trustee shall be protected in
withholding such notice if and so long as a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Debentureholders. 
  
 Section 7.09. Undertaking to Pay Costs. All parties to this
Indenture agree, and each holder of any Debenture by his acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including
reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 7.09 (to the extent
permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Debentureholder, or group of Debentureholders, holding in the aggregate more than 10% in principal amount of the Debentures at the time
outstanding determined in accordance with Section 9.04, or to any suit instituted by any Debentureholder for the enforcement of the payment of the principal of or premium, if any, accrued and unpaid interest, including Contingent Interest, if any,
or accrued and unpaid Liquidated Damages, if any, on any Debenture (including, but not limited to, the Repurchase Price or Designated Event Repurchase Price with respect to the Debentures being repurchased as provided in this Indenture) on or after
the due date expressed in such Debenture or to any suit for the enforcement of the right to convert any Debenture in accordance with the provisions of Article 15.

 ARTICLE 8 
 CONCERNING THE TRUSTEE 
  
 Section 8.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of
Default and after the curing or waiver of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not
been cured or waived) the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the
conduct of such person’s own affairs. 
  
 No provision of
this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that 
  
 (a) prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have
occurred: 
  
 (i) the duties and obligations of
the Trustee shall be determined solely by the express provisions of this Indenture and, after it has been qualified thereunder, the Trust Indenture Act, and the Trustee shall not be liable except for the performance of such duties and obligations as
are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture and the Trust Indenture Act against the Trustee; and 
  
 (ii) in the absence of bad faith and willful misconduct on the part of the Trustee, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such
certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture;

  
 (b) the Trustee shall not be liable for any error of judgment
made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be established by a court of competent jurisdiction that the Trustee was negligent in ascertaining the pertinent facts; 
  
 (c) the Trustee shall not be liable with respect to any action taken or
omitted to be taken by it in good faith in accordance with the direction of the holders of not less than a majority in principal amount of the Debentures at the time outstanding determined as provided in Section 9.04 relating to the time, 

  

 46 







 
method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under
this Indenture; 
  
 (d) whether or not therein provided, every
provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section; 
  
 (e) the Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or
any other matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-registrar with respect to the Debentures; 
  
 (f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires
notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred, unless such Responsible Officer of the Trustee had actual knowledge of such event; 

 
 (g) in the absence of written investment direction from the Company, all
cash received by the Trustee shall be placed in a non-interest bearing trust account. In no event shall the Trustee be liable for the selection of investments or for investment losses incurred thereon or for losses incurred as a result of the
liquidation of any such investments prior to its stated maturity or the failure of the party directing such investments prior to its stated maturity or the failure of the party directing such investment to provide timely written investment
direction, and the Trustee shall have no obligation to invest or reinvest any amounts held hereunder in the absence of such written investment direction from the Company; and 
  
 (h) in the event that the Trustee is also acting as Custodian, Debenture Registrar, Paying Agent, Conversion Agent or
transfer agent hereunder, the rights and protections afforded to the Trustee pursuant to this Article 8 shall also be afforded to such Custodian, Debenture Registrar, Paying Agent, Conversion Agent or transfer agent. 
  
 None of the provisions contained in this Indenture shall require the Trustee
to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds
or adequate indemnity against such risk or liability is not assured to it. 
  

 47 







 Section 8.02. Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section
8.01: 
  
 (a) the Trustee may conclusively rely and shall be fully
protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, note, coupon or other paper or document believed by it in good faith to be genuine and to have been signed or
presented by the proper party or parties; 
  
 (b) any request,
direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officers’ Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors
may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company; 
  
 (c) the Trustee may consult with counsel and require an opinion of counsel and any advice of such counsel or Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 
  

(d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction
of any of the Debentureholders pursuant to the provisions of this Indenture, unless such Debentureholders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which may be incurred
therein or thereby; 
  
 (e) the Trustee shall not be bound to make
any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion,
may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the
Company, personally or by agent or attorney; provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the
opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require indemnity satisfactory to the Trustee from the Debentureholders against such expenses or liability
as a condition to so proceeding; the reasonable expenses of every such examination shall be paid by the Company or, if paid by the Trustee or any predecessor Trustee, shall be repaid by the Company upon demand; and 
  
 (f) the Trustee may execute any of the trusts or powers hereunder or perform
any duties hereunder either directly or by or through agents, custodians, nominees or attorneys and the Trustee shall not be responsible for any misconduct 

  

 48 







 
or negligence on the part of any agent, custodian, nominee or attorney appointed by it with due care hereunder. 
  
 In no event shall the Trustee be liable for any consequential loss or damage
of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action other than through the Trustee’s willful misconduct or gross
negligence. The Trustee shall not be charged with knowledge of any default or Event of Default with respect to the Debentures, unless either (1) a Responsible Officer shall have actual knowledge of such default or Event of Default or (2) written
notice of such default or Event of Default shall have been given to the Trustee by the Company or by any holder of the Debentures; and the permissive rights of the Trustee enumerated herein shall not be construed as duties. 
  
 Section 8.03. No Responsibility for Recitals, Etc. The recitals
contained herein and in the Debentures (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the Debentures. The Trustee shall not be accountable for the use or application by the Company of any Debentures or the proceeds of any Debentures authenticated and delivered
by the Trustee in conformity with the provisions of this Indenture. 
  
 Section 8.04. Trustee, Paying Agents, Conversion Agents or Registrar May Own Debentures. The Trustee, any Paying Agent, any Conversion Agent or Debenture registrar, in its individual or any other capacity, may become the owner or
pledgee of Debentures with the same rights it would have if it were not Trustee, Paying Agent, Conversion Agent or Debenture registrar. 
  
 Section 8.05. Monies to Be Held in Trust. Subject to the provisions of Section 13.04, all monies received by the Trustee shall, until used or
applied as herein provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as may be agreed from time to time by the Company and the Trustee. 
  
 Section 8.06. Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the
Trustee shall be entitled to, reasonable compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to
in writing between the Trustee and the Company, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements 

  

 49 







 
and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and
the expenses and disbursements of its agents and counsel and of all persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence, willful misconduct or bad faith. The Company also covenants
to indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and its agents and any authenticating agent for, and to hold them harmless against, any loss, liability or
expense incurred without negligence, willful misconduct or bad faith on the part of the Trustee, its officers, directors, agents or employees, or such agent or authenticating agent, as the case may be, and arising out of or in connection with the
acceptance or administration of this trust or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim of liability in the premises. The obligations of the Company under this Section 8.06 to
compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a lien prior to that of the Debentures upon all property and funds held or collected by the Trustee as such, except,
subject to the effect of Section 7.06, funds held in trust herewith for the benefit of the holders of particular Debentures prior to the date of the accrual of such unpaid compensation or indemnifiable claim. The Trustee’s right to receive
payment of any amounts due under this Section 8.06 shall not be subordinate to any other liability or indebtedness of the Company (even though the Debentures may be so subordinated). The obligation of the Company under this Section 8.06 shall
survive the satisfaction and discharge of this Indenture and the earlier resignation or removal or the Trustee. The indemnification provided in this Section 8.06 shall extend to the officers, directors, agents and employees of the Trustee.

  
 When the Trustee and its agents and any authenticating agent
incur expenses or render services after an Event of Default specified in Section 7.01(g) or Section 7.01(h) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy,
insolvency or similar laws. 
  
 Section 8.07. Officers’
Certificate as Evidence. Except as otherwise provided in Section 8.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to
taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, be deemed
to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee, and such Officers’ Certificate, in the absence of negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, shall
be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof. 
  

 50 







 Section 8.08. Conflicting Interests of Trustee. After qualification under the Trust
Indenture Act, if the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the
provisions of, the Trust Indenture Act and this Indenture. 
  
 Section 8.09. Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at
least $50,000,000. If such person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such
person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this Article. 
  
 Section 8.10. Resignation or Removal of Trustee. 
  
 (a) The Trustee may at any time resign by giving written notice of such resignation to the Company and by mailing notice thereof to the Debentureholders at their addresses as they shall appear on the Debenture
register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the
resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment sixty (60) days after the mailing of such notice of resignation to the Debentureholders, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee, or any Debentureholder who has been a bona fide holder of a Debenture or Debentures for at least six months may, subject to the provisions of
Section 7.09, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor
trustee. 
  
 (b) In case at any time any of the following shall
occur: 
  
 (i) the Trustee shall fail to comply
with Section 8.08 within a reasonable time after written request therefor by the Company or by any Debentureholder who has been a bona fide holder of a Debenture or Debentures for at least six (6) months, or 
  
 (ii) the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.09 and shall fail to resign after written request therefor by the Company or by any such Debentureholder, or 
  

 51 







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

  
 then, in any such case, the Company may by a Board Resolution remove the
Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to
the provisions of Section 7.09, any Debentureholder who has been a bona fide holder of a Debenture or Debentures for at least six (6) months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 
  
 (c) The holders of a majority in aggregate principal amount of the Debentures
at the time outstanding may at any time remove the Trustee and nominate a successor trustee which shall be deemed appointed as successor trustee unless within ten (10) days after notice to the Company of such nomination the Company objects thereto,
in which case the Trustee so removed or any Debentureholder, upon the terms and conditions and otherwise as in Section 8.10(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee. 
  
 (d) Any resignation or removal of the Trustee and appointment of a successor
trustee pursuant to any of the provisions of this Section 8.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.11. 
  
 Section 8.11. Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 8.10
shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor
trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written
request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 8.06, execute and deliver an instrument transferring to such successor trustee all
the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all
such 

  

 52 







 
rights and powers. Any trustee ceasing to act shall, nevertheless, retain a lien upon all property and funds held or collected by such trustee as such,
except for funds held in trust for the benefit of holders of particular Debentures, to secure any amounts then due it pursuant to the provisions of Section 8.06. 
  
 No successor trustee shall accept appointment as provided in this Section 8.11 unless at the time of such acceptance such
successor trustee shall be qualified under the provisions of Section 8.08 and be eligible under the provisions of Section 8.09. 
  
 Upon acceptance of appointment by a successor trustee as provided in this Section 8.11, each of the Company and the former trustee, at the written
direction and at the expense of the Company shall mail or cause to be mailed notice of the succession of such trustee hereunder to the Debentureholders at their addresses as they shall appear on the Debenture register. If the Company fails to mail
such notice within ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 
  
 Section 8.12. Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged
or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all of the
corporate trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto,
provided that in the case of any corporation succeeding to all or substantially all of the corporate trust business of the Trustee such corporation shall be qualified under the provisions of Section 8.08 and eligible under the provisions of Section
8.09. 
  
 In case at the time such successor to the Trustee shall
succeed to the trusts created by this Indenture, any of the Debentures shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent
appointed by such predecessor trustee, and deliver such Debentures so authenticated; and in case at that time any of the Debentures shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such
successor trustee may authenticate such Debentures either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the
Debentures or in this Indenture provided that the certificate of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Debentures in the name
of any predecessor 

  

 53 







 
Trustee shall apply only to its successor or successors by merger, conversion or consolidation. 
  
 Section 8.13. Limitation on Rights of Trustee as Creditor. If and when the Trustee shall be or become a
creditor of the Company (or any other obligor upon the Debentures), after qualification under the Trust Indenture Act, the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of the claims against the
Company (or any such other obligor). 
  
 Section 8.14.
Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee
that affects the rights of the holders of the Debentures under this Indenture, including, without limitation, under Article IV hereof) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee
under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in
such application on or after the date specified in such application (which date shall not be less than three (3) Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented
in writing to any earlier date), unless, prior to taking any such action (or the effective date in the case of any omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or
omitted. 
  
 ARTICLE 9 
 CONCERNING THE DEBENTUREHOLDERS 
  
 Section 9.01. Action by Debentureholders. Whenever in this Indenture it is provided that the holders of
a specified percentage in aggregate principal amount of the Debentures may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of
taking any such action, the holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Debentureholders in person or by agent or proxy appointed in
writing, or (b) by the record of the Debentureholders voting in favor thereof at any meeting of Debentureholder duly called and held in accordance with the provisions of Article 10, or (c) by a combination of such instrument or instruments and any
such record of such a meeting of Debentureholders. Whenever the Company or the Trustee solicits the taking of any action by the holders of the Debentures, the Company or the Trustee may fix in advance of such solicitation, a date as the record date
for determining Debentureholders entitled to take such action. The record date shall 

  

 54 







 
be not more than fifteen (15) days prior to the date of commencement of solicitation of such action. 
  
 Section 9.02. Proof of Execution by Debentureholders. Subject
to the provisions of Section 8.01, Section 8.02 and Section 10.05, proof of the execution of any instrument by a Debentureholder or his agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be
prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Debentures shall be proved by the Debenture register or by a certificate of the Debenture registrar. The record of any Debentureholders’ meeting
shall be proved in the manner provided in Section 10.06. 
  
 Section 9.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Debenture registrar may deem the person in whose name such Debenture shall be registered
upon the Debenture register to be, and may treat him as, the absolute owner of such Debenture (whether or not such Debenture shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the
Company or any Debenture registrar) for the purpose of receiving payment of or on account of the principal of, premium, if any, accrued and unpaid interest, including Contingent Interest, if any, and accrued and unpaid Liquidated Damages, if any, on
such Debenture, for conversion of such Debenture and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Debenture registrar shall be affected by any notice to the contrary. All such
payments so made to any holder for the time being, or upon his order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such Debenture. Notwithstanding
anything to the contrary in this Indenture or the Debentures following an event which, after notice or passage of time or both, would become a Default, any holder of a beneficial interest in a Global Debenture may directly enforce against the
Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other person, such holder’s right to exchange such beneficial interest for a Debenture in certificated form in accordance with the
provisions of this Indenture. 
  
 Section 9.04. Company-Owned
Debentures Disregarded. In determining whether the holders of the requisite aggregate principal amount of Debentures have concurred in any direction, consent, waiver or other action under this Indenture, Debentures that are owned by the Company
or any other obligor on the Debentures or by any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any other obligor on such Debentures shall be disregarded and deemed not to be
outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, 

  

 55 







 
waiver or other action only Debentures that a Responsible Officer knows are so owned shall be so disregarded. Debentures so owned that have been pledged in
good faith may be regarded as outstanding for the purposes of this Section 9.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to vote such Debentures and that the pledgee is not the Company, any other
obligor on the Debentures or a person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any such other obligor. In the case of a dispute as to such right, any decision by the Trustee
taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Debentures, if any, known by the
Company to be owned or held by or for the account of any of the above described persons; and, subject to Section 8.01, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and

included in the Debentures the holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 9.02, revoke such action so far as concerns
such Debenture. Except as aforesaid, any such action taken by the holder of any Debenture shall be conclusive and binding upon such holder and upon all future holders and owners of such Debenture and of any Debentures issued in exchange or
substitution therefor, irrespective of whether any notation in regard thereto is made upon such Debenture or any Debenture issued in exchange or substitution therefor.

meeting and one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting.

such additional covenant, restriction or condition such supplemental indenture may provide for a particular period of grace 

  

 59 







 
after default (which period may be shorter or longer than that allowed in the case of other defaults) or may provide for an immediate enforcement upon such
default or may limit the remedies available to the Trustee upon such default; 
  
 (e) to increase, from time to time, the per annum interest rate on the Debentures for any period;

transfer and assignment of any property thereunder, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or
otherwise. 
  
 Any supplemental indenture authorized by the
provisions of this Section 11.01 may be executed by the Company and the Trustee without the consent of the holders of any of the Debentures at the time outstanding, notwithstanding any of the provisions of Section 11.02. 
  
 Notwithstanding any other provision of the Indenture or the Debentures, the
Registration Rights Agreement and the obligation to pay Liquidated Damages thereunder may be amended, modified or waived solely in accordance with the provisions of the Registration Rights Agreement.

 Section 11.02. Supplemental Indentures With Consent of Debentureholders. With the consent
(evidenced as provided in Article 9) of the holders of not less than a majority in aggregate principal amount of the Debentures at the time outstanding (determined in accordance with Article 9), the Company, when authorized by the resolutions of the

which the Debentures are payable, or impair the right to convert the Debentures into Common Stock, cash or other property receivable upon conversion, subject to the terms set forth herein, including Section 15.05, or reduce the number of shares of
Common Stock or the amount of any other property receivable upon conversion of the Debentures, reduce the quorum or voting requirement for the Debentures as set forth in this Indenture, modify the provisions of this Section 11.02, except to increase

by such modification or waiver without the consent of the holder of each such Debenture so affected, or (ii) reduce the aforesaid percentage of Debentures, the holders of which are required to consent to any such supplemental indenture, without the
consent of the holders of all Debentures then outstanding. 
  
 Upon the written request of the Company, accompanied by a copy of the Board Resolutions authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Debentureholders as

Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 
  

 61 







 It shall not be necessary for the consent of the Debentureholders under this Section 11.02 to approve the
particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. 
  
 Section 11.03. Effect of Supplemental Indentures. Any supplemental indenture executed pursuant to the provisions of this Article 11 shall
comply with the Trust Indenture Act, as then in effect, provided that this Section 11.03 shall not require such supplemental indenture or the Trustee to be qualified under the Trust Indenture Act prior to the time such qualification is in fact
required under the terms of the Trust Indenture Act or the Indenture has been qualified under the Trust Indenture Act, nor shall it constitute any admission or acknowledgment by any party to such supplemental indenture that any such qualification is
required prior to the time such qualification is in fact required under the terms of the Trust Indenture Act or the Indenture has been qualified under the Trust Indenture Act. Upon the execution of any supplemental indenture pursuant to the

this Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section
17.11) and delivered in exchange for the Debentures then outstanding, upon surrender of such Debentures then outstanding. 
  
 Section 11.05. Evidence of Compliance of Supplemental Indenture to Be Furnished Trustee. In addition to the documents required by Section

 ARTICLE 12 
 CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 
  
 Section 12.01. Company May Consolidate, Etc. on Certain Terms.
Subject to the provisions of Section 12.02 and notwithstanding anything to the contrary in this Indenture, the Company shall not consolidate or merge with or into any other Person (whether or not affiliated with the Company), or sell, convey or
lease its assets and properties substantially as an entirety to any Person unless the Company is the surviving Person or the Person formed by such consolidation or into which the Company is merged or the Person that acquires by conveyance or
transfer, or that leases the assets and properties of the Company substantially as an entirety shall be a corporation organized under the laws of the United States of America, any state thereof or the District of Columbia; and unless, after giving
effect to any such consolidation, merger, sale, conveyance or lease, there shall be no Event of Default under this Indenture, and no event which, after notice or passage of time or both, would become an Event of Default. Further, upon any such
consolidation, merger, sale, conveyance or lease, the due and punctual payment of the principal of and premium, if any, accrued and unpaid interest, including Contingent Interest, if any, and accrued and unpaid Liquidated Damages, if any, on all of
the Debentures, according to their terms, and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed by the Company, shall be expressly assumed by supplemental indenture satisfactory
in form to the Trustee, executed and delivered to the Trustee by the Person (if other than the Company) formed by such consolidation, or into which the Company shall have been merged, or which shall have acquired or leased the Company’s assets
or properties substantially as an entirety, and such supplemental indenture shall provide for the applicable conversion rights set forth in Article 15. 
  
 Section 12.02. Successor Corporation to Be Substituted. In case of any such consolidation, merger, sale, conveyance or lease and upon the
assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and premium, if any, accrued and unpaid interest,
including Contingent Interest, if any, and accrued and unpaid Liquidated Damages, if any, on all of the Debentures and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company, such
successor Person shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such successor Person thereupon may cause to be signed, and may issue either in its own name or
in the name of BlackRock, Inc. any or all of the Debentures issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor corporation instead of the Company and
subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to 

  

 63 







 
be authenticated and delivered, any Debentures which previously shall have been signed and delivered by the officers of the Company to the Trustee for
authentication, and any Debentures which such successor corporation thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Debentures so issued shall in all respects have the same legal rank and benefit under this
Indenture as the Debentures theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Debentures had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale,
conveyance or lease, the person named as the “Company” in the first paragraph of this Indenture or any successor which shall thereafter have become such in the manner prescribed in this Article 12 may be dissolved, wound up and liquidated
at any time thereafter and such person shall be released from its liabilities as obligor and maker of the Debentures and from its obligations under this Indenture. 
  
 In case of any such consolidation, merger, sale, conveyance or lease, such changes in phraseology and form (but not in
substance) may be made in the Debentures thereafter to be issued as may be appropriate. 
  
 Section 12.03. Opinion of Counsel to Be Given Trustee. The Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale,
conveyance or lease and any such assumption complies with the provisions of this Article 12.

Debentures shall have been authenticated and delivered) and not theretofore canceled, or (b) all the Debentures not theretofore canceled or delivered to the Trustee for cancellation shall have become due and payable, and the Company shall deposit
with the Trustee, in trust, funds sufficient to pay at maturity or at redemption all of the Debentures (other than any Debentures that shall have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Debentures

 64 







 
then this Indenture shall cease to be of further effect except as to (i) the right to receive payments of principal of and premium, if any, and accrued and
unpaid interest, including Contingent Interest, if any, and accrued and unpaid Liquidated Damages, if any, on, the Debentures and the other rights, duties and obligations of Debentureholders, as beneficiaries hereof with respect to the amounts, if
any, so deposited with the Trustee, (ii) the rights, obligations and immunities of the Trustee hereunder and (iii) the obligations of the Company under Section 8.06, and the Trustee, on written demand of the Company accompanied by an Officers’
Certificate and an Opinion of Counsel as required by Section 17.05 and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture; the Company, however, hereby agrees to
reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred by the Trustee and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this Indenture or
the Debentures. 
  
 Section 13.02. Deposited Monies to Be Held
in Trust by Trustee. Subject to Section 13.04, all monies deposited with the Trustee pursuant to Section 13.01 shall be held in trust and applied by it to the payment, either directly or through any Paying Agent (including the Company if
acting as its own Paying Agent), to the holders of the particular Debentures for the payment of which such monies have been deposited with the Trustee, of all sums due and to become due thereon for principal and premium and accrued and unpaid
interest, including Contingent Interest, if any, and accrued and unpaid Liquidated Damages, if any. 
  
 Section 13.03. Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of this Indenture, all monies then held by any Paying
Agent of the Debentures (other than the Trustee) shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such Paying Agent shall be released from all further liability with respect to such monies.

  
 Section 13.04. Return of Unclaimed Monies.
Subject to the requirements of applicable law, any monies deposited with or paid to the Trustee for payment of the principal of, premium, if any, or accrued and unpaid interest, including Contingent Interest, if any, and accrued and unpaid
Liquidated Damages, if any, on Debentures (including any Principal Return, Redemption Price, Repurchase Price or Designated Event Repurchase Price) and not applied but remaining unclaimed by the Debentureholders for two years after the date upon
which the principal of, premium, if any, or accrued and unpaid interest, including Contingent Interest, if any, or accrued and unpaid Liquidated Damages, if any, on such Debentures, as the case may be, shall have become due and payable, shall be
repaid to the Company by the Trustee on written request and all liability of the Trustee shall thereupon cease with respect to such monies; and the holder of any of the Debentures shall thereafter look only to the Company for any payment which such
holder may be entitled to collect unless an applicable abandoned 

  

 65 







 
property law designates another person. The Trustee shall, promptly after such payment of the principal of, premium, if any, or accrued and unpaid interest,
including Contingent Interest, if any, or accrued and unpaid Liquidated Damages, if any, on Debentures (including any Principal Return, Redemption Price, Repurchase Price or Designated Event Repurchase Price), as described in this Section 13.04 and
upon written request of the Company, return to the Company any funds in excess of the amount required for such payment. 
  
 Section 13.05. Reinstatement. If (i) the Trustee or the Paying Agent is unable to apply any money in accordance with Section 13.02 by reason
of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application and (ii) the holders of at least a majority in principal amount of the then outstanding Debentures so request by written
notice to the Trustee, the Company’s obligations under this Indenture shall be revived and reinstated as though no deposit had occurred pursuant to Section 13.01 until such time as the Trustee or the Paying Agent is permitted to apply all such
money in accordance with Section 13.02; provided, however, that if the Company makes any payment of interest, including Contingent Interest, or Liquidated Damages on or principal of any Debenture following the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Debentureholders to receive such payment from the money held by the Trustee or Paying Agent.

 ARTICLE 15 
 CONVERSION OF DEBENTURES 
  
 Section 15.01. Conversion Privilege.  
  
 (a) Subject to the conditions described below, and upon compliance with the provisions of this Article 15, a Debentureholder
shall have the right, at such holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Debenture at any time prior to the close of business on the
Business Day immediately preceding February 15, 2035 into cash and fully paid and shares of Class A Common Stock, if any, at a rate (the “Conversion Rate”) of 9.7282 shares of Class A Common Stock (subject to adjustment as provided
in this Indenture) per $1,000 principal amount of Debenture (the “Conversion Obligation”); provided that, prior to the close of business on the Business Day immediately preceding February 15, 2009 holders may convert their
Debentures only as described below: 
  
 (i)
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 Debentures for each day of such Measurement Period
was less than 103% of the product of the Last Reported Sale Price on such date and the Conversion Rate on such date, all as determined by the Trustee, as provided below. 
  
 (ii) as provided in Section 15.01(b), Section 15.01(c), and Section 15.01(d). 
  
 The Trustee shall not determine the Trading Price of the Debentures unless
requested by the Company to do so in writing, and the Company shall have no obligation to make such request unless a Debentureholder provides the Company with reasonable evidence that the Trading Price of the Debentures would be less than 103% of
the product of (a) the then-applicable Conversion Rate of the Debentures and (b) the Last Reported Sale Price at such time, at which time the Company shall instruct the Trustee to determine the Trading Price of the Debentures beginning on the next
Trading Day and on each successive Trading Day until the Trading Price per Debenture is greater than or equal to 103% of the product of (a) the then-applicable Conversion Rate of the Debentures and (b) the Last Reported Sale Price on such date.

  
 If the condition set forth in Section 15.01(a)(i) above has
been met, the Company shall so notify the Debentureholders. If after the condition in Section 15.01(a)(i) has been met, the Trading Price per $1,000 principal amount of Debentures is greater than 103% of the product of the Last Reported Sale Price
of Class A Common Stock and the Conversion Rate for such date, the Company shall so notify the Debentureholders. The Company shall disseminate a press release through Dow Jones & Company, Inc. or Bloomberg Business News 

  

 67 







 
stating that the condition in Section 15.01(a)(i) has been met or ceased to be met (or publish the information on its website or through such other public
medium it may use at that time). 
  
 “Trading
Price” means, with respect to each $1,000 principal amount of Debentures (as used in this definition, a “Debenture”) as of any date (each such date a “date of determination”), the average of the secondary market bid
quotations per Debenture obtained by the Trustee for $2,000,000 principal amount of Debentures at approximately 3:30 p.m., New York City time, on such determination date from three independent nationally recognized securities dealers selected by the
Company; provided that if three such bids cannot reasonably be obtained by the trustee, but two such bids are obtained, then the average of the two bids shall be used, and if only one such bid can reasonably be obtained by the Trustee, that
one bid shall be used. If the Trustee cannot reasonably obtain at least one such bid for $2,000,000 principal amount of Debentures from a nationally recognized securities dealer, then the Trading Price of a Debenture will be deemed to be less than
103% of the product of (a) the then-applicable Conversion Rate of the Debentures and (b) the Last Reported Sale Price on such date of determination. 
  
 (b) In the event that: 
  
 (i) the Company distributes to all holders of Class A Common Stock rights entitling them to purchase, for a period expiring within 45 days
after such distribution, Class A Common Stock at less than the average of the Last Reported Sale Prices of Class A Common Stock for the 10 Trading Days preceding the announcement of such distribution; or 
  
 (ii) the Company distributes to all holders of Common Stock
assets or debt securities of the Company or rights to purchase the Company’s securities, which distribution has a per share value exceeding 10% of the Last Reported Sale Price of the Class A Common Stock on the Trading Day immediately preceding
the date of declaration of such distribution, 
  
 then, in each case, the
Debentures may be surrendered for conversion at any time on and after the date that the Company gives notice to the holders of such right, which shall be not less than 20 days prior to the Ex-Dividend Date for such distribution, until the earlier of
the close of business on the Business Day immediately preceding the Ex-Dividend Date or the date the Company announces that such distribution will not take place. Notwithstanding the foregoing, the Debentures will not be convertible pursuant to
clauses (i) or (ii) above if the Company provides that Debentureholders shall participate in such distribution without conversion. 
  

 68 







 (c) In the event that the Company is party to a consolidation, merger, binding share exchange or sale or
transfer of all or substantially all of the Company’s assets, in each case pursuant to which the Class A Common Stock would be converted into cash, securities or other property, a Debentureholder may surrender Debentures for conversion at any
time from and after the date that is 15 days prior to the anticipated effective date of the transaction until 15 days after the actual date of such transaction, unless such transaction occurs on or prior to February 15, 2010 and also constitutes a
Change of Control (regardless of whether such transaction is excluded from the definition pursuant to the penultimate paragraph thereof) (in which case the Debentures will instead be convertible in accordance with Section 15.01(d) below). The
Company shall notify Debentureholders and the Trustee (whether or not such transaction also constitutes a Change of Control) at the same time the Company publicly announces such transaction (but in no event less than 15 days prior to the effective
date of such transaction). Following the effective date of such transaction, the right to convert the Debentures at the Conversion Rate, and the settlement thereof, shall be modified as set forth under Section 15.05. 
  
 (d)(i) In the event that a Change of Control (regardless of
whether such transaction is excluded from the definition pursuant to the penultimate paragraph thereof and disregarding for this purpose the exception set forth in clause (ii)(B) of the definition of Change of Control) occurs on or prior to February
15, 2010, a Debentureholder may surrender Debentures for conversion at any time from and after the date that is 15 days before the anticipated effective date of such Change of Control until the Designated Event Repurchase Date relating to such
Change of Control. The Company shall give notice to all record Debentureholders and the Trustee at least 20 Trading Days prior to the anticipated effective date of any such Change of Control. Such notice will also specify whether the Company made
the election specified in Section 15.01(e)(i) hereof. 
  
 (ii) If a Debentureholder elects to convert Debentures in connection with a Change of Control (disregarding for this purpose the exception set forth in clause (ii)(B) of the definition of Change of Control) pursuant to this subsection at
any time from and after the date that is 15 days prior to the anticipated effective date of the transaction until 15 days after the actual date of such transaction, the Conversion Rate for such converting Debentureholder shall be increased by an
additional number of shares of Common Stock (the “Additional Shares”) as described below. 
  
 The number of Additional Shares shall be determined by reference to the table attached as Schedule A hereto, based on the effective date of such Change of
Control transaction (the “Effective Date”) and the Stock Price; provided that if the Stock Price is between two Stock Price amounts in the table or such Effective Date is between two Effective Dates in the table, the number
of Additional Shares 

  

 69 







 
shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the next higher and next lower Stock Price amounts
and the two nearest Effective Dates, as applicable, based on a 365-day year; provided further that if the Stock Price is above $300.00 per share of Common Stock (subject to adjustment), no Additional Shares will be added to the Conversion
Rate; and provided that if the Stock Price is below $77.58 per share (subject to adjustment), no Additional Shares will be added to the Conversion Rate. 
  

The Stock Prices set forth in the first row of the table in Schedule A hereto shall be adjusted as of any date on which the Conversion Rate of the
Debentures is 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 the 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 within the table shall be adjusted in the same manner as the Conversion Rate as set forth in Section 15.03 (other than
by operation of an adjustment to the Conversion Rate by adding Additional Shares). 
  
 Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock issuable upon conversion exceed 12.8882 shares per $1,000 principal amount of Debentures, subject to adjustment in the same
manner as the Conversion Rate as set forth in Section 15.03. 
  
 Any conversion of Debentures in connection with a Change of Control as provided in this subsection, and the settlement thereof, shall be as set forth in Section 15.05. 
  
 (e) Notwithstanding the foregoing, and in lieu of adjusting the Conversion Rate as set forth in Section 15.01(a)(ii), in the
case of a Public Acquirer Change of Control, the Company may elect that, from and after the Effective Date of such Public Acquirer Change of Control, the right to convert a Debenture will be changed into a right to convert a Debenture into a number
of shares of Acquirer Common Stock specified below. The Conversion Rate on and following the Effective Date of such Public Acquirer Change of Control shall be a number of shares of Acquirer Common Stock equal to the product of: 
  
 (i) the Conversion Rate in effect immediately prior to the
Effective Date of such Public Acquirer Change of Control, times 
  
 (ii) the average of the quotients obtained, for each Trading Day in the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Effective Date of such Public Acquirer Change of Control
(the “Valuation Period”), of: 
  
 (A) the Acquisition Value of Class A Common Stock on each such Trading Day in the Valuation Period, divided by 
  

 70 







 (B) the Last Reported Sale Price of the Acquirer Common Stock on each such Trading Day in
the Valuation Period. 
  
 Section 15.02. Conversion
Procedure. 
  
 (a) Upon conversion of any Debenture,
subject to this Section 15.02 and Section 15.01 and Section 15.05, the Company shall satisfy the Conversion Obligation with respect to such Debenture by payment and delivery of cash and, if applicable, shares of Class A Common Stock, the aggregate
value of which (the “Conversion Value”) shall be equal to the product of: 
  
 (i)(A) the aggregate principal amount of Debentures to be converted divided by 1,000 multiplied by (B) the then applicable Conversion Rate
(plus Additional Shares, if any); and 
  
 (ii)
the average of the daily Volume Weighted Average Price of Class A Common Stock for each of the ten consecutive Trading Days (appropriately adjusted to take into account the occurrence during such period of stock splits and similar events) beginning
on the second Trading Day immediately following the day the Debentures are tendered for conversion (the “Ten Day Weighted Average Price”). 
  
 (b) The Company shall deliver the Conversion Value to converting holders as follows: 
  
 (i) an amount in cash (the “Principal Return”) equal to the lesser of (A) the Conversion
Value of the Debentures to be converted and (B) the aggregate principal amount of the Debentures to be converted; 
  
 (ii) if the Conversion Value of the Debentures to be converted is greater than the Principal Return, an amount in whole shares of Class A
Common Stock (the “Net Shares”), determined as set forth below, equal to such aggregate Conversion Value less the Principal Return (the “Net Share Amount”); and 
  
 (iii) an amount in cash, in lieu of any fractional shares of
Class A Common Stock as set forth below. 
  
 The number of Net
Shares to be paid shall be determined by dividing the Net Share Amount by the Ten Day Weighted Average Price. Debentureholders will not receive fractional shares upon conversion of Debentures. In lieu of 

  

 71 







 
fractional shares, holders will receive cash for the value of the fractional shares, which cash payment shall be based on the Ten Day Weighted Average Price.

  
 The Conversion Value, Principal Return, number of Net Shares
and Net Share Amount shall be determined by the Company at the end of the ten consecutive Trading Day period (the “Determination Date”) beginning on the second Trading Day immediately following the day the Debentures are tendered
for conversion; provided that with respect to any Debentures surrendered for conversion pursuant to Section 15.01(d) above, the Determination Date shall be the last Trading Day in the period on which the applicable Stock Price is determined
(pursuant to the definition thereof) in connection with the determination of Additional Shares, if any, to be added to the Conversion Rate. 
  
 (c) Before any holder of a Debenture shall be entitled to convert the same as set forth above, such holder shall (1) in the case of a Global Debenture,
comply with the procedures of the Depositary in effect at that time and furnish appropriate endorsement and transfer documents, and (2) in the case of a Debenture issued in certificated form, surrender such Debentures, duly endorsed to the Company
or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, and give irrevocable written notice to the Conversion Agent in the form on the reverse of such certificated Debenture (or a
facsimile thereof) (a “Notice of Conversion”) at said office or place that such holder elects to convert the same and shall state in writing therein the principal amount of Debentures to be converted and the name or names (with
addresses) in which such holder wishes the certificate or certificates for the Net Shares, if any, included upon settlement the Conversion Obligation, if any, to be registered. No Notice of Conversion with respect to any Debentures may be tendered
by a holder thereof if such holder has also tendered a Repurchase Notice or Designated Event Repurchase Notice and not validly withdrawn such Repurchase Notice or Designated Event Repurchase Notice in accordance with Section 16.03. 
  
 If more than one Debenture shall be surrendered for conversion at one time by
the same holder, the Conversion Obligation with respect to such Debentures, if any, that shall be payable upon conversion shall be computed on the basis of the aggregate principal amount of the Debentures (or specified portions thereof to the extent
permitted thereby) so surrendered. 
  
 (d) A Debenture shall be
deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”) that is the later of: (i) the date the holder has complied with the requirements set forth in clause (c) above or (ii) the
Determination Date. Payment of the cash and Net Shares, if any, in satisfaction of the Conversion Obligation shall be made by the Company promptly following the Determination Date, but in no event later than three Business Days thereafter (the
“Conversion Settlement Date”) by paying in cash 

  

 72 







 
the Principal Return (together with any cash in lieu of fractional shares) to the holder of a Debenture surrendered for conversion, or such holder’s
nominee or nominees, and 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 number of full shares of
Class A Common Stock equal to the Net Shares, if any, to which such holder shall be entitled as part of such Conversion Obligation. 
  
 (e) In case any Debenture shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon
the written order of the holder of the Debenture so surrendered, without charge to such holder, a new Debenture or Debentures in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered
Debentures. 
  
 (f) If a holder submits a Debenture for
conversion, the Company shall pay all stamp and other duties, if any, which may be imposed by the United States or any political subdivision thereof or taxing authority thereof or therein with respect to the issuance of shares of Class A Common
Stock, if any, upon the conversion. However, the holder shall pay any such tax which is due because the holder requests any Net Shares to be issued in a name other than the holder’s name. The Trustee may refuse to deliver the certificates
representing the shares of Class A Common Stock being issued in a name other than the holder’s name until the Trustee receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the
holder’s name. Nothing herein shall preclude any tax withholding required by law or regulations. 
  
 (g) Except as provided in Section 15.03, no adjustment shall be made for dividends on any shares issued upon the conversion of any Debenture as provided
in this Article. 
  
 (h) Upon the conversion of an interest in a
Global Debenture, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Debenture as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any
conversion of Debentures effected through any Conversion Agent other than the Trustee. 
  
 (i) (i) Debentureholders at the close of business on a record date will receive payment of interest payable on the corresponding interest payment date notwithstanding the conversion of such Debentures at any time
after the close of business on such record date. Debentures surrendered for conversion during the period from the close of business on any record date to the opening of business on the corresponding interest payment date must be accompanied by
payment of an amount equal to the interest that the holder is to receive on the Debentures; provided, however, that no such payment need be made (1) if the Company has 

  

 73 







 
specified a Redemption Date that is after a record date but on or prior to the next interest payment date, (2) if the Company has specified a Repurchase Date
following a Designated Event that is after a record date but on or prior to the next succeeding interest payment date or (3) to the extent of any overdue interest, overdue Contingent Interest or Liquidated Damages, if any, at the time of conversion
with respect to such Debenture. Except as described above, no payment or adjustment will be made for accrued interest on converted Debentures. 
  
 (ii) The Person in whose name the certificate for such shares of Class A Common Stock is registered shall be treated as a stockholder of
record on and after the Conversion Date; provided, however, that no surrender of Debentures on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the Person or Persons entitled to receive
the shares of Class A Common Stock upon such conversion as the record holder or holders of such shares of Class A Common Stock on such date, but such surrender shall be effective to constitute the Person or Persons entitled to receive such shares of
Class A Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; such conversion shall be at the Conversion Rate in effect on the date that
such Debentures shall have been surrendered for conversion, as if the stock transfer books of the Company had not been closed. Upon conversion of Debentures, such Person shall no longer be a Debentureholder. 
  
 Section 15.03. Adjustment of Conversion Rate. The Conversion
Rate shall be adjusted from time to time by the Company as follows: 
  
 (a) In case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Class A Common Stock in shares of Class A Common Stock, the Conversion Rate shall be increased so that the same shall equal the
rate determined by multiplying the Conversion Rate in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution by a fraction, 
  
 (i) the numerator of which shall be the sum of the number of
shares of Class A Common Stock outstanding at the close of business on the date fixed for the determination of stockholders entitled to receive such dividend or other distribution plus the total number of shares of Class A Common Stock constituting
such dividend or other distribution; and 
  
 (ii)
the denominator of which shall be the number of shares of Class A Common Stock outstanding at the close of business on the date fixed for such determination, 

  

 74 







 
such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. If any dividend or
distribution of the type described in this Section 15.03(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

  
 (b) In case the Company shall issue rights or warrants to all
holders of its outstanding shares of Class A Common Stock entitling them (for a period expiring within forty-five (45) days after the record date fixed for such issuance) to subscribe for or purchase shares of Class A Common Stock at a price per
share less than the average of the Last Reported Sale Prices of the Class A Common Stock for the ten (10) Trading Days immediately preceding the declaration date for such distribution, the Conversion Rate shall be increased so that the same shall
equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the declaration date for such distribution by a fraction, 
  
 (i) the numerator of which shall be the number of shares of Class A Common Stock outstanding at the close of business on the declaration
date for such distribution plus the total number of additional shares of Class A Common Stock offered for subscription or purchase, and 
  
 (ii) the denominator of which shall be the sum of the number of shares of Class A Common Stock outstanding at the close of business on the
declaration date for such distribution plus the number of shares that the aggregate offering price of the total number of shares so offered would purchase at a price equal to the average of the Last Reported Sale Prices of the Class A Common Stock
for the 10 Trading Days immediately preceding the declaration date for such distribution. 
  
 Such adjustment shall be successively made whenever any such rights or warrants are issued, and shall become effective immediately after the opening of business on the day following the declaration date for such
distribution. To the extent that shares of Class A Common Stock are not delivered after the expiration of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made
upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Class A Common Stock actually delivered. If such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be
the Conversion Rate that would then be in effect if such declaration date for such distribution had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Class A Common Stock at a
price less than the average of the Last Reported Sale Prices of the Class A Common Stock for the 10 Trading Days immediately preceding the declaration date for such distribution, and in determining the aggregate offering price of such shares of
Class A Common Stock, there shall be taken into account any consideration received by 

  

 75 







 
the Company for such rights or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be
determined by the Board of Directors. 
  
 (c) In case outstanding
shares of Class A Common Stock shall be subdivided into a greater number of shares of Class A Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be
proportionately increased, and conversely, in case outstanding shares of Class A Common Stock shall be combined into a smaller number of shares of Class A Common Stock, the Conversion Rate in effect at the opening of business on the day following
the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such
subdivision or combination becomes effective. 
  
 (d) In case the
Company shall, by dividend or otherwise, distribute to all holders of its Class A Common Stock shares of any class of Capital Stock of the Company or evidences of its indebtedness, cash or other assets (including securities, but excluding (1) any
Class A Common Stock, rights or warrants referred to in Section 15.03(a) or Section 15.03(b), (2) dividends and distributions (A) in connection with the liquidation, dissolution or winding up of the Company or (B) paid exclusively in cash and (3)
any Capital Stock, evidences of indebtedness, cash or assets distributed upon a merger or consolidation to which Section 15.05 applies) (any of such shares of Capital Stock, indebtedness, cash (excluding any such cash dividends to the extent that
the amount of such cash together with any cash dividends paid on the Class A Common Stock during the quarter in which the distribution referred to in Section 15.03(e) occurs, do not exceed the Dividend Threshold Amount) or other property hereinafter
in this Section 15.03(d)) called the “Distributed Property”)), then, in each such case (unless the Company distributes such Distributed Property for distribution to the Debentureholders on such dividend or distribution date (as if
each Debentureholder had converted such Debenture entirely into Class A Common Stock immediately prior to the Record Date (as defined in Section 15.03(h)(iii) for such distribution or dividend of Distributed Property)) the Conversion Rate shall be
increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect on the Record Date with respect to such distribution by a fraction, 
  
 (i) the numerator of which shall be the Current Market Price on such Record Date; and 
  
 (ii) the denominator of which shall be the Current Market
Price on such Record Date less the fair market value (as determined by the Board of Directors, whose determination shall be conclusive, and 

  

 76 







 
described in a resolution of the Board of Directors) on the Record Date of the portion of the Distributed Property so distributed applicable to one share of
Class A Common Stock, 
  
 such adjustment to become effective immediately prior to
the opening of business on the day following such Record Date; provided that if the then fair market value (as so determined) of the portion of the Distributed Property so distributed applicable to one share of Class A Common Stock is equal
to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Debentureholder shall have the right to receive upon conversion the amount of Distributed Property
such holder would have received had such holder converted each Debenture entirely into Class A Common Stock on the Record Date. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion
Rate that would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 15.03(d) by reference to the actual or when issued
trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price on the applicable Record Date. 
  
 Notwithstanding the foregoing, if the Distributed Property distributed by the Company to all holders of its Class A Common
Stock consist of Capital Stock of, or similar equity interests in, a Subsidiary or other business unit of the Company, the Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate
in effect on the Record Date with respect to such distribution by a fraction, 
  
 (i) the numerator of which shall be the sum of (A) the average of the Last Reported Sale Prices of the Class A Common Stock for the ten (10) Trading Days commencing on and including the fifth Trading Day after the
Ex-Dividend Date plus (B) the fair market value of the securities distributed in respect of each share of Class A Common Stock for which this Section 15.03(d) applies, which shall equal the number of securities distributed in respect of each share
of Class A Common Stock multiplied by the average of the Last Reported Sale Prices of those securities distributed for the ten (10) Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Date; and 
  
 (ii) the denominator of which shall be the average of the
Last Reported Sale Prices of the Class A Common Stock for the ten (10) Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Date, 
  

 77 







 such adjustment to become effective immediately prior to the opening of business on the day following such Record Date;
provided that the Company may in lieu of the foregoing adjustment make adequate provision so that each Debentureholder shall have the right to receive upon conversion the amount of Distributed Property such holder would have received had such holder
converted its Debentures entirely into Class A Common Stock on the Record Date with respect to such distribution. 
  
 Rights or warrants distributed by the Company to all holders of Class A Common Stock entitling the holders thereof to subscribe for or purchase shares of
the Company’s Capital Stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares
of Class A Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Class A Common Stock, shall be deemed not to have been distributed for purposes of this Section 15.03 (and no adjustment to the Conversion
Rate under this Section 15.03 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate
shall be made under this Section 15.03(d). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights or warrants
become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or
warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any
Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 15.03 was made,
(1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such
distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Class A Common Stock with respect to such rights or warrants (assuming
such holder had retained such rights or warrants), made to all holders of Class A Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated without
exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued. 
  

 78 







 For purposes of this Section 15.03(d), Section 15.03(a), and Section 15.03(b), any dividend or
distribution to which this Section 15.03(d) is applicable that also includes shares of Class A Common Stock, or rights or warrants to subscribe for or purchase shares of Class A Common Stock to which Section 15.03(b) applies (or both), shall be
deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or shares of capital stock other than such shares of Class A Common Stock or rights or warrants to which Section 15.03(b) applies (and any Conversion Rate
adjustment required by this Section 15.03(d) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Class A Common Stock or such rights or warrants (and any further
Conversion Rate adjustment required by Section 15.03(a) and Section 15.03(b) with respect to such dividend or distribution shall then be made), except (A) the Record Date of such dividend or distribution shall be substituted as “the date fixed
for the determination of stockholders entitled to receive such dividend or other distribution”, “the date fixed for the determination of stockholders entitled to receive such rights or warrants” and “the date fixed for such
determination” within the meaning of Section 15.03(a) and Section 15.03(b) and (B) any shares of Class A Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on the date fixed for
such determination” within the meaning of Section 15.03(a). 
  
 (e) In case the Company shall, by dividend or otherwise, distribute cash to all holders of its Class A Common Stock (excluding (I) any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary, or (II) any cash dividends paid on the Class A Common Stock to the extent that the aggregate cash dividends per share of Class A Common Stock in such quarter, together with the amount of cash, if any, excluded from
the definition of Distributed Property with respect to any distribution referred to in Section 15.03(d) occurring in such quarter, do not exceed $0.30, subject to adjustment as set forth below (the “Dividend Threshold Amount”)) then
the Conversion Rate shall be adjusted by multiplying the Conversion Rate in effect immediately prior to the close of business on the Record Date for such dividend or distribution by a fraction, 
  
 (i) the numerator of which shall be the Current Market Price
on such record date minus the Dividend Threshold Amount; and 
  
 (ii) the denominator of which shall be the Current Market Price on such record date minus the amount of cash so distributed applicable to one share of Class A Common Stock, 
  
 such adjustment to be effective immediately prior to the opening of business on the day
following the record date; provided that if the portion of the cash so distributed applicable to one share of Class A Common Stock is equal to or 

  

 79 







 
greater than the Current Market Price on the record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Debentureholder
shall have the right to receive upon conversion of a Debenture (or any portion thereof) the amount of cash such holder would have received had such holder converted such Debenture (or portion thereof) entirely into Class A Common Stock on the Record
Date. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
  
 The Dividend Threshold Amount shall be subject to adjustments from time to
time in a manner inversely proportional to adjustments to the Conversion Rate, provided that following any transaction or event described in Section 15.05 as a result of which the Debentures are convertible, into property that includes shares
of Common Stock other than Class A Common Stock, the Dividend Threshold Amount will be the Dividend Threshold Amount immediately prior to the effective date of such transaction or event multiplied by a fraction, 
  
 (x) the numerator of which shall be (A) if such shares of Common Stock are
traded on a United States national or regional securities exchange or quoted on the Nasdaq National Market, the average of the Last Reported Sale Prices of such shares for the five Trading Day period commencing on the Trading Day immediately
following such effective date and (B) otherwise, the fair market value of such shares as determined in good faith by the Board of Directors, and 
  
 (y) the denominator of which shall be the average of the Last Reported Sale Prices of the Class A Common Stock for the five Trading Day period ending on
the Trading Day immediately preceding such effective date. 
  
 For
the avoidance of doubt, for purposes of this Section 15.03(e), in the event of any reclassification of the Class A Common Stock, as a result of which the Debentures become convertible into more than one class of Common Stock, whether cash dividends
or distributions in any quarter exceed the Dividend Threshold Amount shall be determined based on the aggregate cash dividends or distributions paid in such quarter on all classes of Common Stock into which the Debentures are convertible and if an
adjustment to the Conversion Rate is required pursuant to this Section 15.03(e), references in this Section to one share of Class A Common Stock or to the Current Market Price or Last Reported Sale Price of one share of Class A Common Stock shall be
deemed to refer to a unit or to the price of a unit consisting of the number of shares of each class of Common Stock into which the Debentures are then convertible equal to the numbers of shares of such class issued in respect of one share of Class
A Common Stock in such reclassification. The above provisions of this paragraph shall similarly apply to successive reclassifications. 
  

 80 







 (f) In case a tender or exchange offer made by the Company or any Subsidiary for all or any portion of
the Class A Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of consideration per share of Class A Common Stock having a Fair Market Value (as determined
by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors) that as of the last time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or
exchange offer (as it may be amended) exceeds the Last Reported Sale Price of a share of Class A Common Stock on the Trading Day next succeeding the Expiration Time, the Conversion Rate shall be increased so that the same shall equal the rate
determined by multiplying the Conversion Rate in effect immediately prior to the Expiration Time by a fraction, 
  
 (i) the numerator of which shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the aggregate consideration payable
to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted up to any such
maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of shares of Class A Common Stock outstanding (less any Purchased Shares) at the Expiration Time and the Last Reported Sale Price of a share of
Class A Common Stock on the Trading Day next succeeding the Expiration Time, and 
  
 (ii) the denominator of which shall be the number of shares of Class A Common Stock outstanding (including any Purchased Shares) at the
Expiration Time multiplied by the Last Reported Sale Price of a share of Class A Common Stock on the Trading Day next succeeding the Expiration Time, 
  
 such adjustment to become effective immediately prior to the opening of business on the day following the Expiration Time. If the Company is obligated to purchase shares
pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate
that would then be in effect if such tender or exchange offer had not been made. 
  
 (g) In case of a tender or exchange offer made by a Person other than the Company or any Subsidiary for an amount that increases the offeror’s ownership of Class A Common Stock to more than 25% of the Class A
Common Stock outstanding and shall involve the payment by such Person of consideration per share of Class A Common Stock having a Fair Market Value (as determined 

  

 81 







 
by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) that as of the last time (the
“Offer Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it shall have been amended) that exceeds the Closing Price of a share of Class A Common Stock on the Trading Day next succeeding
the Offer Expiration Time, and in which, as of the Offer Expiration Time the Board of Directors is not recommending rejection of the offer, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the
Conversion Rate in effect immediately prior to the Offer Expiration Time by a fraction 
  
 (i) the numerator of which shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the aggregate consideration payable
to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Offer Expiration Time (the shares deemed so accepted, up to
any such maximum, being referred to as the “Accepted Purchased Shares”) and (y) the product of the number of shares of Class A Common Stock outstanding (less any Accepted Purchased Shares) at the Offer Expiration Time and the Last
Reported Sale Price of a share of Class A Common Stock on the Trading Day next succeeding the Offer Expiration Time, and 
  
 (ii) the denominator of which shall be the number of shares of Class A Common Stock outstanding (including any Accepted Purchased Shares)
at the Offer Expiration Time multiplied by the Last Reported Sale Price of a share of Class A Common Stock on the Trading Day next succeeding the Offer Expiration Time, 
  
 such adjustment to become effective immediately prior to the opening of business on the day following the Offer Expiration Time. If such
Person is obligated to purchase shares pursuant to any such tender or exchange offer, but such Person is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again
be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made. Notwithstanding the foregoing, the adjustment described in this Section 15.03(g) shall not be made if, as of the Offer Expiration
Time, the offering documents with respect to such offer disclose a plan or intention to cause the Company to engage in any transaction described in Article 12. 
  

(h) For purposes of this Section 15.03, the following terms shall have the meaning indicated: 
  
 (i) “Current Market Price” shall have the
meaning set forth in Section 1.01, except that if another issuance, distribution, subdivision or 

  

 82 







 
combination to which Section 15.03 applies occurs during the period applicable for calculating “Current Market Price” pursuant to the definition
thereof, “Current Market Price” shall be calculated for such period in a manner determined by the Board of Directors to reflect the impact of such issuance, distribution, subdivision or combination on the Last Reported Sale Price of the
Class A Common Stock during such period. 
  
 (ii)
“Fair Market Value” shall mean the amount which a willing buyer would pay a willing seller in an arm’s-length transaction. 
  
 (iii) “Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the
holders of Class A Common Stock have the right to receive any cash, securities or other property or in which the Class A Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other
property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). 
  
 (i) The Company may make such increases in the Conversion Rate, in addition
to those required by clauses (a), (b), (c), (d), (e), (f) or (g) of this Section 15.03 as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting
from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. 
  
 (j) To the extent permitted by applicable law, the Company from time to time may increase the Conversion Rate by any amount if the Board of Directors
shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the
holder of each Debenture at his last address appearing on the Debenture register provided for in Section 2.06 a notice of the increase at least one full Business Day 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. 
  
 (k) All calculations under this Article 15 shall be made by the Company and shall be made to the nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be. No adjustment shall be made
for the Company’s issuance of rights to purchase Class A Common Stock pursuant to a Company plan for reinvestment of dividends or interest or for any issuance of Class A Common Stock or convertible or exchangeable securities or rights to


  

 83 







 
purchase Common Stock or convertible or exchangeable securities, other than as provided in this Section 15.03. To the extent the Debentures become
convertible into cash, assets, property or securities, no adjustment need be made thereafter upon the issuance of the cash, assets, property or such securities or upon the issuance of any cash, assets, property or securities that are issued upon
exercise or conversion of any securities issued upon the conversion of the Debentures. Interest will not accrue on any cash into which the Debentures are convertible. 
  
 (l) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any
Conversion Agent other than the Trustee an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the
Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume 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 the holder of each Debenture at his last address appearing on the Debenture register provided for in Section 2.06 of this Indenture, within twenty (20) days of the effective date of such
adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 
  
 (m) In any case in which this Section 15.03 provides that an adjustment shall become effective immediately after (1) a record date or Record Date for an
event, (2) the date fixed for the determination of stockholders entitled to receive a dividend or distribution pursuant to Section 15.03(a), (3) a date fixed for the determination of stockholders entitled to receive rights or warrants pursuant to
Section 15.03(b), or (4) the Expiration Time or Offer Expiration Time, as the case may be, for any tender or exchange offer pursuant to Section 15.03(f) or Section 15.03(g), (each an “Adjustment Determination Date”), the Company may
elect to defer until the occurrence of the applicable Adjustment Event (as hereinafter defined) (x) issuing to the holder of any Debenture converted after such Adjustment Determination Date and before the occurrence of such Adjustment Event, the
additional shares of Common Stock or other securities issuable upon such conversion by reason of the adjustment required by such Adjustment Event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment
and (y) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 15.03. For purposes of this Section 15.03(m), the term “Adjustment Event” shall mean: 
  
 (i) in any case referred to in clause (1) hereof, the
occurrence of such event, 
  

 84 







 (ii) in any case referred to in clause (2) hereof, the date any such dividend or
distribution is paid or made, 
  
 (iii) in any
case referred to in clause (3) hereof, the date of expiration of such rights or warrants, and 
  
 (iv) in any case referred to in clause (4) hereof, the date a sale or exchange of Common Stock pursuant to such tender or exchange offer
is consummated and becomes irrevocable. 
  
 (n) For purposes of
this Section 15.03, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of
Common Stock. The Company will not pay any dividend or make any distribution on shares of Class A Common Stock held in the treasury of the Company. 
  
 Section 15.04 Shares to Be Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or
shares held in treasury, sufficient shares of Class A Common Stock to provide for conversion of the Debentures from time to time as such Debentures are presented for conversion. 
  
 Section 15.05. Effect of Reclassification, Consolidation, Merger or Sale. If any of the following events
occur, namely (i) any reclassification or change of the outstanding shares of Class A Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a split, subdivision or
combination), (ii) any consolidation, merger or combination of the Company with another Person as a result of which holders of Class A Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with
respect to or in exchange for such Class A Common Stock, or (iii) any sale or conveyance of all or substantially all of the properties and assets of the Company to any other Person as a result of which holders of Class A Common Stock shall be
entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Class A Common Stock, then: 
  
 (a) the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall
comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing for the conversion and settlement of the Debentures as set forth in this
Indenture. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article or pursuant to Section 15.01(e), as the case may be. If, in the case of
any such reclassification, change, consolidation, merger, 

  

 85 







 
combination, sale or conveyance, the Exchange Property includes shares of stock or other securities and assets of a corporation other than the successor or
purchasing corporation, as the case may be, in such reclassification, change, consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional
provisions to protect the interests of the holders of the Debentures 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 repurchase rights set forth in Article 16 herein. 
  
 In the event the Company shall execute a supplemental indenture pursuant to this Section 15.05, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefore, the kind or amount of
shares of stock or other securities or property (including cash) that will constitute the Exchange Property after any such reclassification, change, combination, consolidation, merger, sale or conveyance, 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 Debentureholders. 
  
 (b) Notwithstanding the provisions of Section 15.02(a), and subject to the provisions of Section 15.01, including, without limitation, Section 15.01(e),
the Conversion Value with respect to each $1,000 principal amount of Debentures tendered for conversion on or after the second Trading Day immediately preceding the effective date of any such transaction, shall be calculated (as provided in clause
(d) below) based on the kind and amount of shares of stock and other securities or property or assets (including cash) or any combination thereof received upon such reclassification, change, consolidation, merger, combination, sale or conveyance by
a holder of Class A Common Stock holding, immediately prior to the transaction, a number of shares of Class A Common Stock equal to the Conversion Rate (plus Additional Shares, to the extent that the holder is entitled to Additional Shares in
accordance with Section 15.01(d) upon conversion) immediately prior to such transaction (the “Exchange Property”), assuming such holder of Class A Common Stock did not exercise his rights of election, if any, as to the kind or
amount of securities, cash or other property receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance (provided that, if the kind or amount of securities, cash or other property receivable upon such
reclassification, change, consolidation, merger, combination, sale or conveyance is not the same for each share of Class A Common Stock in respect of which such rights of election shall not have been exercised (“non-electing
share”), then for the purposes of this Section 15.05 the kind and amount of securities, cash or other property receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance for each non-electing share
shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). 
  

 86 







 (c) The Conversion Value in respect of any Debentures tendered for conversion on or after the second
Trading Day immediately preceding the effective date of any such transaction shall be equal to the average of the daily values of the Exchange Property pertaining to such Debentures as determined in the next sentence (the “Exchange Property
Value”) for each of the ten consecutive Trading Days (appropriately adjusted to take into account the occurrence during such period of stock splits and similar events) beginning on the later of (A) the second Trading Day immediately
following the day the Debentures are tendered for conversion and (B) the effective date of such transaction (the “Exchange Property Weighted Average Price”). For the purpose of determining the value of any Exchange Property:

  
 (i) Any shares of common stock of the
successor or purchasing corporation or any other corporation that are included in the Exchange Property shall be valued as set forth in Section 15.02 as if such shares were “Common Stock” using the procedures set forth in the definition of
“Last Reported Sale Price” in Section 1.01; and 
  
 (ii) Any other property (other than cash) included in the Exchange Property shall be valued in good faith by the Board of Directors or by a New York Stock Exchange member firm selected by the Board of Directors.

  
 (d) The Company shall deliver such Conversion Value to
holders of Debentures so converted as follows: 
  
 (i) An amount equal to the Principal Return, determined as set forth in Section 15.02(b)(i); and 
  
 (ii) If the Conversion Value of the Debentures so converted is greater than the Principal Return, an amount of Exchange Property,
determined as set forth below, equal to such aggregate Conversion Value less the Principal Return (the “Net Exchange Property Amount”). 
  
 The amount of Exchange Property to be delivered shall be determined by dividing the Net Exchange Property Amount by the Exchange Property Weighted Average
Price. If the Exchange Property includes more than one kind of property, the amount of Exchange Property of each kind to be delivered shall be in the proportion that the Exchange Property Value of such kind of Exchange Property bears to the Exchange
Property Value of all the Exchange Property. If the foregoing calculations would require the Company to deliver a fractional share or unit of Exchange Property to a holder of Debentures being converted, the Company shall deliver cash in lieu of such
fractional share or unit based on its Exchange Property Weighted Average Price. 
  

 87 







 (e) Notwithstanding clauses (b), (c) and (d) above, if the Debentures are tendered for conversion prior
to the effective date of any such transaction pursuant to Section 15.01(d) above, and the Principal Return and Net Shares, if any, have been determined, but have not been delivered prior to the effective date of such transaction, then the Company
shall (i) pay the Principal Return in cash and (ii) subject to Section 15.01(e), instead of delivering Net Shares, if applicable, deliver an amount of Exchange Property that a holder of Common Stock, holding, immediately prior to the transaction, a
number of shares of Common Stock equal to the Net Shares, would receive, assuming such holder of Common Stock did not exercise his rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such
reclassification, change, consolidation, merger, combination, sale or conveyance (provided that, if the kind or amount of securities, cash or other property receivable upon such reclassification, change, consolidation, merger, combination, sale or
conveyance is not the same for each non-electing share, then for the purposes of this Section 15.05 the kind and amount of securities, cash or other property receivable upon such reclassification, change, consolidation, merger, combination, sale or
conveyance for each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). If the foregoing calculations would require the Company to deliver a fractional share or unit of
Exchange Property to a holder of Debenture being converted, the Company shall deliver cash in lieu of such fractional share or unit based on the Exchange Property Value (as so determined). 
  
 (f) Notwithstanding clauses (b), (c), (d) and (e) above, if Debentures are
tendered for conversion at a time when neither of the ten day weighted averaging periods contemplated in clause (c) or clause (e) applies in full to the determination of the Conversion Value, then the Conversion Value and the amount of cash and
Exchange Property comprising the Principal Return and the Net Shares will be determined proportionally, with the weighted average amount relating to the portion of the ten day period falling prior to the effective date being valued as contemplated
by clause (e) and with the weighted average amount relating to the portion of that period falling on or after the effective date being valued as contemplated by clause (c). 
  
 (g) The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Debentureholder, at
his address appearing on the Debenture register provided for in this Indenture, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 
  
 (h) The above provisions of this Section shall similarly apply to successive
reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. 
  

 88 







 Section 15.06. Certain Covenants. 
  
 (a) Before taking any action which would cause an adjustment reducing the Conversion Rate below the then par value, if any,
of the shares of Common Stock issuable upon conversion of the Debentures, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common
Stock at such adjusted Conversion Rate. 
  
 The Company covenants
that all shares of Common Stock issued upon conversion of Debentures will be fully paid and non-assessable by the Company and free from all taxes, liens and changes 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 Debentures hereunder require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will in good faith and as
expeditiously as possible, to the extent then permitted by the rules and interpretations of the Commission (or any successor thereto), endeavor to secure such registration or approval, as the case may be. 
  
 (c) The Company further covenants that if at any time the Common Stock shall
be listed on any other national securities exchange or automated quotation system the Company will, if permitted and required by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so
listed on such exchange or automated quotation system, all Common Stock issuable upon conversion of the Debentures. 
  
 Section 15.07. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to
any Debentureholder to determine the Conversion Rate or whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the
method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares
of Common Stock, or of any securities or property, which may at any time be issued or delivered upon the conversion of any Debenture; 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 

  

 89 







 
Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into
pursuant to Section 15.05 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Debentureholders upon the conversion of their Debentures after any event referred to in such Section 15.05 or
to any adjustment to be made with respect thereto, but, subject to the provisions of Section 8.01, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate
(which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. 
  
 Section 15.08. Notice to Holders Prior to Certain Actions. In case: 
  
 (a) the Company shall declare a dividend (or any other distribution) on its Class A Common Stock that would
require an adjustment in the Conversion Rate pursuant to Section 15.03; or 
  
 (b) the Company shall authorize the granting to all of the holders of its Class A Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants; or 

 
 (c) of any reclassification of the Class A Common Stock
of the Company (other than a subdivision or combination of its outstanding Class A Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company
is a party and for which approval of any shareholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or 
  
 (d) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company; 
  
 the Company shall cause to be filed with the Trustee and to be mailed to each Debentureholder
at his address appearing on the Debenture register, provided for in Section 2.06 of this Indenture, as promptly as possible but in any event at least ten days prior to the applicable date hereinafter specified, a notice stating (x) the date on which
a record is to be taken for the purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Class A Common Stock of record to be entitled to such dividend, distribution or
rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders
of Class A Common Stock of record shall be entitled to exchange their Class A Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up.
Failure to give such notice, or any defect therein, shall 

  

 90 







 
not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or
winding-up. 
  
 Section 15.09. Shareholder Rights Plans.
Each share of Common Stock issued upon conversion of Debentures pursuant to this Article 15 shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion
shall bear such legends, if any, in each case as may be provided by the terms of any shareholder rights plan adopted by the Company, as the same may be amended from time to time. If at the time of conversion, however, the rights have separated from
the shares of Common Stock in accordance with the provisions of the applicable shareholder rights agreement so that the holders of the Debentures would not be entitled to receive any rights in respect of Common Stock issuable upon conversion of the
Debentures, the Conversion Rate will be adjusted as provided in Section 15.03(d). 
  
 ARTICLE 16 
 REPURCHASE OF DEBENTURES AT
OPTION OF HOLDERS 
  
 Section 16.01. Repurchase at Option of Holders.  
  
 (a) Debentures shall be purchased by the Company at the option of the holder for cash on February 15, 2010, 2015, 2020, 2025, 2030, or the next Business Day after each such date if any such date is not a Business Day (each, a
“Repurchase Date”), at a purchase price (the “Repurchase Price”) equal to 100% of the principal amount of the Debentures to be repurchased. The Company shall pay any accrued and unpaid interest, including Contingent
Interest, if any, and Liquidated Damages, if any, thereon to (but excluding) such Repurchase Date to the holders of such Debentures on the record date immediately preceding such Repurchase Date. Unless the Company has issued a notice of redemption
to redeem the Debentures as set forth in Section 3.01, not later than 20 Business Days prior to any Repurchase Date, the Company shall mail a notice (the “Company Notice”) by first class mail to the Trustee and to each holder (and
to beneficial owners as required by applicable law). The notice shall include a form of repurchase notice to be completed by a holder and shall state: 
  
 (i) the Repurchase Price and the Conversion Rate; 
  
 (ii) the name and address of the Paying Agent and the Conversion Agent; 
  
 (iii) that Debentures as to which a Repurchase Notice has
been given may be converted if they are otherwise convertible only in accordance with Article 15 hereof and the terms of the Debentures if the 

  

 91 







 
applicable Repurchase Notice has been withdrawn in accordance with the terms of this Indenture; 
  
 (iv) that Debentures must be surrendered to the Paying Agent
to collect payment; 
  
 (v) that the Repurchase
Price for any Debenture as to which a Repurchase Notice has been given and not withdrawn will be paid promptly following the later of the Repurchase Date and the time of surrender of such Debenture as described in (iv); 
  
 (vi) the procedures the holder must follow to exercise its
repurchase rights under this Section 16.01 and a brief description of those rights; 
  
 (vii) briefly, the conversion rights, if any, with respect to the Debentures; 
  
 (viii) the procedures for withdrawing a Repurchase Notice;
and 
  
 (ix) the CUSIP number of the Securities.

  
 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 Company Notice shall be prepared by the Company. 
  
 Purchases of Debentures hereunder shall be made, at the option of the holder thereof, upon: 
  
 (A) delivery to the Paying Agent by the holder of a written
notice of repurchase (a “Repurchase Notice”) during the period beginning at any time from the opening of business on the date that is 20 Business Days prior to the relevant Repurchase Date until the close of business on the last
Business Day prior to the Repurchase Date stating: 
  
 (1) the certificate number of the Debentures which the holder will deliver to be purchased or the appropriate Depositary procedures if certificated Debentures have not been issued for such Debenture, 
  
 (2) the portion of the principal amount of the Debenture
which the holder will deliver to be purchased, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000, and 
  

 92 







 (3) that such Debenture shall be purchased by the Company as of the Repurchase Date
pursuant to the terms and conditions specified in the Securities and in this Indenture; and 
  
 (B) delivery of such Debenture to the Paying Agent at any time after delivery of the Repurchase Notice (together with all necessary
endorsements) at the offices of the Paying Agent, such delivery being a condition to receipt by the holder of the Repurchase Price therefor; provided, however, that such Repurchase Price shall be so paid pursuant to this Section 16.01 only if
the Debenture so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Repurchase Notice. 
  
 The Company shall purchase from the holder thereof, pursuant to this Section 16.01, a portion of a Debenture, if the principal amount of such portion is

 Section 16.02.
Repurchase at Option of Holders Upon a Designated Event. 
  
 (a) If there shall occur a Designated Event at any time prior to maturity of the Debentures, then each Debentureholder shall have the right, at such 

  

 93 







 
holder’s option, to require the Company to repurchase all of such holder’s Debentures for cash, or any portion thereof that is a multiple of $1,000
principal amount, on the date (the “Designated Event Repurchase Date”) specified by the Company that is not less than twenty (20) Business Days and not more than thirty five (35) Business Days after the date of the Designated Event
Notice of such Designated Event at a repurchase price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, including Contingent Interest, if any, and accrued and unpaid Liquidated Damages, if any, thereon to, but
excluding, the Designated Event Repurchase Date (the “ Designated Event Repurchase Price”). If such Designated Event Repurchase Date falls after a record date for the payment of interest, Contingent Interest or Liquidated Damages
and on or prior to the corresponding interest payment date, the Company shall instead pay the principal amount to the Debentureholders, and pay the full amount of accrued and unpaid interest, including Contingent Interest, if any, and accrued and
unpaid Liquidated Damages, if any, payable on such interest payment date to the holder of record on the close of business on the corresponding record date. Repurchases of Debentures under this Section 16.02 shall be made, at the option of the holder
thereof, upon: 
  
 (i) delivery to the Trustee
(or other Paying Agent appointed by the Company) by a holder of a duly completed notice (the “Designated Event Repurchase Notice”) in the form set forth on the reverse of the Debenture prior to the close of business on the
Designated Event Repurchase Date; and 
  
 (ii)
delivery or book-entry transfer of the Debentures to the Trustee (or other Paying Agent appointed by the Company) at any time after delivery of the Designated Event Repurchase Notice (together with all necessary endorsements) at the Corporate Trust
Office of the Trustee (or other Paying Agent appointed by the Company) in the Borough of Manhattan, such delivery being a condition to receipt by the holder of the Designated Event Repurchase Price therefor; provided that such Designated
Event Repurchase Price shall be so paid pursuant to this Section 16.02 only if the Debenture so delivered to the Trustee (or other Paying Agent appointed by the Company) shall conform in all respects to the description thereof in the related
Designated Event Repurchase Notice. 
  
 Any purchase by the
Company contemplated pursuant to the provisions of this Section 16.02 shall be consummated by the delivery of the consideration to be received by the holder promptly following the later of the Designated Event Repurchase Date and the time of the
book-entry transfer or delivery of the Debenture. 
  
 Notwithstanding anything herein to the contrary, any holder delivering to the Trustee (or other Paying Agent appointed by the Company) the Designated 

  

 94 







 
Event Repurchase Notice contemplated by this Section 16.02 shall have the right to withdraw such Designated Event Repurchase Notice at any time prior to the
close of business on the Designated Event Repurchase Date by delivery of a written notice of withdrawal to the Trustee (or other Paying Agent appointed by the Company) in accordance with Section 16.03 below. 
  
 The Trustee (or other Paying Agent appointed by the Company) shall promptly
notify the Company of the receipt by it of any Designated Event Repurchase Notice or written notice of withdrawal thereof. 
  
 (b) On or before the fifteenth day after the occurrence of a Designated Event, the Company shall mail to all holders of record of the Debentures a notice
(the “Designated Event Notice”) of the occurrence of such Designated Event and of the repurchase right at the option of the holders arising as a result thereof. Such mailing shall be by first class mail. The Company shall also
deliver a copy of the Designated Event Notice to the Trustee and cause a copy of such Designated Event Notice, or a summary of the information contained therein, to be published once in a newspaper of general circulation in The City of New York.
Concurrently with the mailing of any Designated Event Notice, the Company shall issue a press release announcing such Designated Event referred to in the Designated Event Notice, the form and content of which press release shall be determined by the
Company in its sole discretion. The failure to issue any such press release or any defect therein shall not affect the validity of the Designated Event Notice or any proceedings for the repurchase of any Debenture that any Debentureholder may elect
to have the Company repurchase as provided in this Section 16.02. 
  
 Each Designated Event Notice shall specify the circumstances constituting the Designated Event, the Designated Event Repurchase Date, the Designated Event Repurchase Price, that the holder must exercise the repurchase right on or prior to
the close of business on the Designated Event Repurchase Date (the “Designated Event Expiration Time”), that the holder shall have the right to withdraw any Debentures surrendered prior to the Designated Event Expiration Time, a
description of the procedure which a Debentureholder must follow to exercise such repurchase right and to withdraw any surrendered Debentures, the place or places where the holder is to surrender such holder’s Debentures and the CUSIP number or
numbers of the Debentures (if then generally in use) and include a form of Designated Event Repurchase Notice. 
  
 No failure of the Company to give the foregoing notices and no defect therein shall limit the Debentureholders’ repurchase rights or affect the
validity of the proceedings for the repurchase of the Debentures pursuant to this Section 16.02. 
  

 95 







 (c) Notwithstanding the foregoing, no Debentures may be repurchased by the Company at the option of the
holders upon a Designated Event if the principal amount of the Debentures has been accelerated, and such acceleration has not been rescinded, on or prior to the Designated Event Repurchase Date. 
  
 Section 16.03. Withdrawal of Repurchase Notice or Designated Event
Repurchase Notice.  
  
 (a) A Repurchase Notice or Designated
Event Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Trustee (or other Paying Agent appointed by the Company) in accordance with the Repurchase Notice or Designated Event
Repurchase Notice at any time prior to the close of business on the Business Day prior to the Repurchase Date or prior to the close of business on the Designated Event Repurchase Date, specifying:

which such notice of withdrawal is being submitted, and 
  
 (iii) the principal amount, if any, of such Debenture that remains subject to the original Repurchase Notice or Designated Event Repurchase Notice. 
  
 Section 16.04. Deposit of Repurchase Price or Designated Event Repurchase Price. 
  
 (a) On or prior to the Repurchase Date or Designated Event Repurchase Date,
the Company will 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 5.04) an amount of money sufficient to
repurchase on the Repurchase Date or Designated Event Repurchase Date all of the Debentures to be repurchased on such date at the appropriate Repurchase Price or Designated Event Repurchase Price; provided that if such payment is made on the
Repurchase Date or Designated Event Repurchase Date it must be received by the Trustee or Paying Agent, as the case may be, by 10:00 a.m. New York City time, on such date. Subject to receipt of funds and/or Debentures by the Trustee (or other Paying
Agent appointed by the Company), payment for Debentures surrendered for repurchase (and not withdrawn) prior to the Designated Event Expiration Time will be made promptly after the later of (x) the Repurchase Date or Designated Event Repurchase Date
with respect to such Debenture (provided the holder has satisfied the conditions in 

  

 96 







 
Section 16.01 or Section 16.02, as applicable) and (y) the time of delivery of such Debenture to the Trustee (or other Paying Agent appointed by the Company)
by the holder thereof in the manner required by Section 16.01 or Section 16.02, as applicable) by mailing checks for the amount payable to the holders of such Debentures entitled thereto as they shall appear in the Debenture Register,

the Company, return to the Company any funds in excess of the Repurchase Price or Designated Event Repurchase Price. 
  
 (b) If the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to repurchase on the Repurchase Date or Designated Event
Repurchase Date all the Debentures or portions thereof that are to be purchased as of the Repurchase Date or Designated Event Repurchase Date, then on and after the Business Day following the Repurchase Date or Designated Event Repurchase Date (i)
such Debentures will cease to be outstanding, (ii) interest, including Contingent Interest, if any, and Liquidated Damages, if any, will cease to accrue on such Debentures, and (iii) all other rights of the holders of such Debentures will terminate,
whether or not book-entry transfer of the Debentures has been made or the Debentures have been delivered to the Trustee or Paying Agent, other than the right to receive the Repurchase Price or Designated Event Repurchase Price upon delivery of the

Debentures hereunder, including under Section 2.05, Section 2.06, Section 2.07, Section 2.08 and Section 3.06, as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those Sections
to authenticate and deliver Debentures. For all purposes of this Indenture, the authentication and delivery of Debentures by the authenticating agent shall be deemed to be authentication and delivery of such Debentures “by the Trustee” and
a certificate of authentication executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any requirement hereunder or in the Debentures for the Trustee’s certificate of authentication. Such authenticating agent
shall at all times be a person eligible to serve as trustee hereunder pursuant to Section 8.09. 
  
 Any corporation into which any authenticating agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any

resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of

notice of such appointment to the Company and shall mail notice of such appointment to all Debentureholders as the names and addresses of such holders appear on the Debenture register.

 The provisions of Section 8.02, Section 8.03, Section 8.04, Section 9.03 and this Section 17.11 shall be applicable to any authenticating agent.

  
 Section 17.12. Execution in Counterparts. This
Indenture may be executed in any number of counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument. 
  
 Section 17.13. Tax Treatment of the Debentures. The Company agrees, and by acceptance of a beneficial interest
in a Debenture each holder and any beneficial owner of a Debenture shall be deemed to agree, to treat, for United States federal income tax purposes, the Debentures as debt instruments that are subject to Treasury regulation section 1.1275-4 or any
successor provision (the “contingent payment regulations”). For United States federal income tax purposes, the Company further agrees, and by acceptance of a beneficial interest in a Debenture each holder and any beneficial owner of a
Debenture shall be deemed to agree (i) to treat the cash and the fair market value of any Common Stock received upon the conversion of a Debenture as a contingent payment for purposes of the contingent payment regulations, (ii) to accrue interest
with respect to outstanding Debentures as original issue discount for United States federal income tax purposes (i.e. Tax Original Issue Discount) according to the “noncontingent bond method” set forth in the contingent payment
regulations, using the comparable yield of 5.70% compounded semi-annually, and (iii) to be bound by the Company’s determination of the “projected payment schedule,” within the meaning of the contingent payment regulations, with
respect to the Debentures. Holders or beneficial owners may obtain the issue price, amount of Tax Original Issue Discount, issue date, comparable yield and projected payment schedule, by submitting a written request for it to the Company at the
following address: 40 East 52nd Street, New York, NY 10022, Attention: Chief Financial Officer. 
  
 The Company acknowledges and agrees, and by acceptance of a beneficial
interest in a Debenture each holder and any beneficial owner of a Debenture shall be deemed to acknowledge and agree, that (i) the comparable yield means the annual yield the Company would pay, as of the issue date, on a noncontingent,
nonconvertible, fixed-rate debt instrument with terms and conditions otherwise similar to those of the Debentures and (ii) the comparable yield and the projected payment schedule that a holder or beneficial owner may obtain as described above do not
constitute a representation by the Company regarding the actual amounts that will be paid on the Debentures or the value of the Common Stock into which the Debentures may be converted.

 [FORM OF REVERSE OF
DEBENTURE] 
  
 BLACKROCK, INC. 
 2.625% Convertible Debentures due 2035 
  
 This Debenture is one of a duly authorized issue of Debentures of the Company, designated as its 2.625% Convertible Debentures due 2035 (herein called the
“Debentures”), limited to the aggregate principal amount of $250,000,000 all issued or to be issued under and pursuant to an Indenture dated as of February 23, 2005 (herein called the “Indenture”), between the Company and
JPMorgan Chase Bank, N.A. (herein called the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities
thereunder of the Trustee, the Company and the holders of the Debentures. Additional Debentures 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, premium, if any, and interest, including Contingent Interest, if any, and Liquidated Damages, if any, on all Debentures may be declared, and upon said declaration shall become, due and payable, in the manner,
with the effect and subject to the conditions provided in the Indenture. 
  
 The Company shall pay additional interest (“Contingent Interest”) to the Debentureholders for the periods, at the rates and subject to the conditions set forth in the Indenture. The Company will pay
Contingent Interest, if any, in the same manner and at the same time as it will pay interest as described above. 
  
 Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Redemption Price, Repurchase
Price, and the principal amount on the maturity date, as the case may be, to the holder who surrenders a Debenture to a Paying Agent to collect such payments in respect of the Debenture. The Company will 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 Debentures, and in other circumstances, with the consent of the holders of
not less than a majority in aggregate principal amount of the Debentures at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the
provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Debentures; provided, however, that no such supplemental indenture shall make any of the changes set forth in 

  

 A-7 







 
Section 11.02 of the Indenture, without the consent of the holders of all Debentures then outstanding. It is also provided in the Indenture that, prior to
any declaration accelerating the maturity of the Debentures, the holders of a majority in aggregate principal amount of the Debentures at the time outstanding may on behalf of the holders of all of the Debentures waive any past default or Event of
Default under the Indenture and its consequences except as provided in the Indenture. Any such consent or waiver by the holder of this Debenture (unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and upon
all future holders and owners of this Debenture and any Debentures which may be issued in exchange or substitution hereof, irrespective of whether or not any notation thereof is made upon this Debenture or such other Debentures. 
  
 No reference herein to the Indenture and no provision of this Debenture or of
the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and accrued and unpaid interest, including Contingent Interest, if any, and Liquidated Damages, if any,
on this Debenture at the place, at the respective times, at the rate and in the lawful money herein prescribed. 
  
 The Debentures 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, without payment of any service charge but with payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration or exchange of Debentures, Debentures may be exchanged for a like aggregate principal amount of Debentures of other authorized denominations. 
  
 The Debentures are not subject to redemption through the operation of any
sinking fund. Prior to February 20, 2010, the Debentures will not be redeemable at the Company’s option. Subject to the terms and conditions of the Indenture, beginning on February 20, 2010, the Company, at its option, may redeem the Debentures
for cash at any time as a whole, or from time to time in part, at a price equal to the principal amount of the Debentures redeemed plus accrued and unpaid interest, including Contingent Interest, if any, and Liquidated Damages, if any, on the
Debentures redeemed to (but excluding) the Redemption Date. 
  
 Subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase, at the option of the holder, all or any portion of Debentures held by such holder on February 15, 2010, 2015, 2020, 2025 and 2030, in
integral multiples of $1,000 at a Repurchase Price equal to the principal amount of the Debentures repurchased plus accrued and unpaid interest, including Contingent Interest, if any, and accrued and unpaid Liquidated Damages, if any, on the
Debentures repurchased to (but excluding) the Repurchase Date. 
  

 A-8 







 Upon the occurrence of a “Designated Event,” the holder has the right, at such holder’s
option, to require the Company to repurchase all of such holder’s Debentures or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Designated Event Purchase Date at a price equal to 100% of the principal
amount of the Debentures such holder elects to require the Company to repurchase, together with accrued and unpaid interest, including Contingent Interest, if any, and accrued and unpaid Liquidated Damages, if any, to but excluding the date fixed
for repurchase. The Company or, at the written request of the Company, the Trustee shall mail to all holders of record of the Debentures a notice of the occurrence of a Designated Event and of the repurchase right arising as a result thereof on or
before the fifteenth calendar day after the occurrence of such Designated Event. 
  
 Subject to the provisions of the Indenture, the holder hereof has the right, at its option, upon the occurrence of certain conditions specified in the Indenture and prior to the close of business on the business day
immediately preceding February 15, 2035, to convert any Debentures or portion thereof which is $1,000 or an integral multiple thereof, into cash and, if applicable, shares of Class A Common Stock, at a Conversion Rate specified in the Indenture, as
adjusted from time to time as provided in the Indenture, upon surrender of this Debenture, together with a conversion notice as provided in the Indenture and this Debenture, to the Company at the office or agency of the Company maintained for that
purpose in the Borough of Manhattan, The City of New York, or at the option of such holder, the Corporate Trust Office, and, unless the shares issuable on conversion are to be issued in the same name as this Debenture, duly endorsed by, or
accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the holder or by his duly authorized attorney. The initial Conversion Rate shall be 9.7282 shares for each $1,000 principal amount of Debentures. No
fractional shares of Common Stock will be issued upon any conversion, but an adjustment in cash will be paid to the holder, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of
any Debenture or Debentures for conversion. No adjustment shall be made for dividends or any shares issued upon conversion of such Debenture except as provided in the Indenture. 
  
 Upon due presentment for registration of transfer of this Debenture at the office or agency of the Company in the Borough of
Manhattan, The City of New York, a new Debenture or Debentures of authorized denominations for an equal aggregate principal amount will be issued to the transferee in exchange thereof, subject to the limitations provided in the Indenture, without
charge except for any tax, assessments or other governmental charge imposed in connection therewith. 
  
 The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Debenture registrar may deem and treat the registered
holder hereof as the absolute owner of this Debenture (whether or not this Debenture shall be overdue and notwithstanding any notation of ownership or 

  

 A-9 







 
other writing hereon), for the purpose of receiving payment hereof, or on account hereof, for the conversion hereof and for all other purposes, and neither
the Company nor the Trustee nor any other authenticating agent nor any Paying Agent nor any other Conversion Agent nor any Debenture registrar shall be affected by any notice to the contrary. Notwithstanding the foregoing, the Indenture provides
that following an event which, after notice or passage of time or both, would become a Default, owners of beneficial interests in a Global Debenture may directly enforce against the Company such owners’ right to exchange such beneficial
interest for Debentures in certificated form. All payments made to or upon the order of such registered holder shall, to the extent of the sum or sums paid, satisfy and discharge liability for monies payable on this Debenture. 
  
 No recourse for the payment of the principal of or any premium or accrued and
unpaid interest, including Contingent Interest, if any, or Liquidated Damages, if any, on this Debenture, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the
Company in the Indenture or any indenture supplemental thereto or in any Debenture, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer, director or
subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of
any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released. 
  
 Terms used in this Debenture and defined in the Indenture are used herein as therein defined.
