 THIS REGISTRATION RIGHTS AGREEMENT (this “Agreement”),

 WHEREAS, pursuant to that certain Asset Purchase Agreement by and among the Company, FKI Acquisition Corp. and the Shareholder, among others, dated
February 20, 2008 (the “Purchase Agreement”), the Shareholder is receiving, in partial consideration for the Company’s purchase of substantially all the assets of the Shareholder certain shares of common stock of the
Company (the “Acquired Securities”); and 
 WHEREAS, as a condition to the consummation of the transactions contemplated by
the Purchase Agreement, the Company and the Shareholder have entered into this Agreement to provide certain securities registration rights to the Shareholder. 
 NOW, THEREFORE, in consideration of the premises, the mutual covenants herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto
hereby agree as follows: 
 1. Definitions. As used in this Agreement:

 “Company” shall have the meaning set forth in the preamble hereto. 
 “Person” means an individual, a corporation, a partnership, a trust, a limited liability company, an unincorporated organization or a governmental organization or any agency or political subdivision thereof.

 “Prospectus” shall mean any prospectus that is a part of a Registration Statement, together with all amendments or supplements thereto.

 “Registrable Stock” shall mean the shares of common stock then outstanding issued by the Company to the Shareholder
pursuant to the Purchase Agreement; provided, however, that Registrable Stock shall not be deemed to include (i) any shares after such shares have been registered under the Securities Act and sold pursuant to a registration of such securities,
(ii) for purposes of Section 3, any shares that may be sold without registration under the Securities Act in compliance with Rule 144 without volume restrictions, (iii) any shares sold pursuant to any other exemption from registration
under the Securities Act to a Person who is free to resell such shares without registration under the Securities Act, or (iv) they are sold in a transaction in which rights under this Agreement are not assigned. 

 “Registration Statement” shall mean any registration statement filed with the SEC in
accordance with the Securities Act, together with all amendments or supplements thereto. 
 “SEC” shall mean the United
States Securities and Exchange Commission or any successor to the functions of such agency.

2. Transfer Restrictions. 
 2.1.
Transfer Restrictions. 
 (A) Prior to six (6) months after the Effective Date, no Transfers by any Shareholder shall be
permitted except for Permitted Transfers effected in compliance with Section 2.3. 
 (B) Any purported Transfer not permitted by this
Agreement will be null and void, and the Company shall not record on its share transfer books, register of stockholders or otherwise any such purported Transfer. 
 (C) Nothing in this Agreement shall be deemed to restrict any Transfer or other disposition of Acquired Securities pursuant to the terms of any merger, consolidation or other business combination transaction, or
pursuant to any tender or exchange offer. 
 2.2 Compliance with Securities Laws. Each of the Shareholders hereby agrees that it shall
not, directly or indirectly, Transfer any Acquired Securities unless such Transfer complies with the provisions hereof and, with respect to Shareholders subject thereto, the Company’s policies on insider trading, as in effect from time to time,
and (a) such Transfer is made pursuant to an effective Registration Statement and, if required, has been registered under all applicable state securities or blue sky laws or (b) no such registration is required because of the availability
of an exemption from registration under the Securities Act and all applicable state securities or blue sky laws, and, at the request of the Company, the transferor shall provide to the Company a legal opinion to such effect in form and substance,
and from counsel, reasonably satisfactory to the Company; provided, however, that no such legal opinion shall be necessary in order to effectuate a Transfer pursuant to a Public Offering. 
 2.3 Permitted Transfers. The following shall be considered “Permitted Transfers”: (a) Transfers by a Shareholder to a family
member or family trust or family limited partnership for bona fide estate planning purposes; (b) Transfers by a Shareholder by will or by intestate succession; or (c) Transfers by a Shareholder to an Affiliate, including a stockholder
thereof. Notwithstanding the foregoing, no Transfer by a Shareholder permitted by this Section 2.3 shall be consummated unless and until the proposed transferee agrees in writing to become a party to and be bound by the provisions of this
Agreement to the same extent as the transferring Shareholder (such writing, a “Joinder Agreement”). Upon consummation of any Permitted Transfer by a Shareholder, the Shareholder shall send to the Company a notice of the Permitted

  

 2 

 
Transfer, indicating the number of shares of Acquired Securities transferred, the date of the transfer, and the names and addresses of the transferees, along
with a copy of the Joinder Agreement. For all purposes under this Agreement, such transferee shall thereafter be considered a Stockholder. 
 2.4. Legend on Acquired Securities 
 (A) A copy of this Agreement shall be filed with the Secretary of the Company and kept
with the records of the Company. 
 (B) Each certificate representing Acquired Securities acquired by any Shareholder pursuant to the
Purchase Agreement shall bear legends substantially in the following forms: 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER JURISDICTION. THE SECURITIES MAY NOT BE TRANSFERRED EXCEPT PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN APPLICABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH LAWS OR IN A TRANSACTION OUTSIDE THE UNITED
STATES NOT SUBJECT TO THE SECURITIES ACT. 
 THE SALE, ASSIGNMENT, HYPOTHECATION, PLEDGE, ENCUMBRANCE OR OTHER DISPOSITION (EACH A
“TRANSFER”) OF ANY OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE RESTRICTED BY THE TERMS OF A REGISTRATION RIGHTS AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER NAMED THEREIN, A COPY OF WHICH IS ON FILE WITH THE SECRETARY
OF THE COMPANY. THE COMPANY WILL NOT REGISTER THE TRANSFER OF SUCH SECURITIES ON THE BOOKS OF THE COMPANY UNLESS AND UNTIL THE TRANSFER HAS BEEN MADE IN COMPLIANCE WITH THE TERMS OF THE REGISTRATION RIGHTS AGREEMENT. 
 (C) In the event that any such Acquired Securities are Transferred in a Public Offering, the Company shall promptly upon request, deliver a replacement
certificate not containing the legend set forth in Section 2.4(B) in connection with such Transfer. 
 (D) Upon the delivery to the
Company of a legal opinion reasonably satisfactory to the Company to the effect that the legend set forth in Section 2.4(B) is no longer 

  

 3 

 
required by the Securities Act and any applicable state securities law, the Company shall promptly upon request deliver a replacement certificate not
containing the legend in exchange for the legended certificate. 
 3. S-3 Registration Rights. 
 (A) Subject to the Transfer restrictions set forth in Sections 2.1 and 2.2 and to Sections 3(B), (C) and (D) below, if at any time
following six (6)months after the Effective Date, the Company is a registrant entitled to use Form S-3 or any successor thereto to register Registrable Stock, the Shareholder may request the Company in writing to use its diligent efforts to register
all of the Registrable Stock, as requested by the Shareholder, under the Securities Act on Form S-3 or a successor thereto (the “S-3 Registration Right”). 
 (B) Following exercise of the S-3 Registration Right, the Company will use its reasonable best efforts to effect the registration of all of the
Registrable Stock under the Securities Act and, provided an exemption from registration or qualification does not exist, the registration or qualification thereof under applicable state securities or blue sky laws, but only to the extent provided
for in the following provisions of this Agreement. Upon receipt of the notice pursuant to Section 3(A), the Company will use its reasonable best efforts to effect the registration under the Securities Act of the Registrable Stock, all to
the extent requisite to permit such sale or other disposition by such holders of the Registrable Stock so registered. 
 (C) The
Shareholder’s right to exercise the S-3 Registration Right shall be subject to the following limitations: 
 (1) The Company shall not
be required to effect a registration pursuant to the exercise of the S-3 Registration Right more than once. 
 (2) The number of shares of
Registrable Stock to be registered pursuant to the exercise of such right must equal or exceed $800,000 in value in the aggregate. 
 (D)
Notwithstanding anything to the contrary in this Section 3, (i) the Company shall not be required to effect the filing of a Registration Statement pursuant to this Section 3 during the period beginning 60 days prior to
the Company’s good faith estimate, as certified in writing by an executive officer of the Company to the Shareholder, of the proposed date of filing of, and ending 120 days or 180 days if requested by the underwriter, following the effective
date of, a Registration Statement relating to an offering of equity securities on account of the Company, and (ii) the Company shall be entitled to postpone or suspend the filing or effectiveness of the Registration Statement required under
this Section 3, as certified in writing by an executive officer of the Company to the Shareholder, that such registration and offering would interfere with any business interest or planned transaction of the Company, including any
financing, acquisition, disposition, corporate reorganization or other transaction involving the Company or that the filing would not be in the best interest of the Company or that the filing of a Registration Statement would require public
disclosure of any such event prior to the time that such disclosure would otherwise be required. 
  

 4 

 (E) The Company shall not be required to effect the filing of a Registration Statement pursuant to this
Section 3 in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance unless the
Company is already subject to service in such jurisdiction and except as may be required by the Securities Act. 
 4. Piggyback
Registration Rights. 
 (A) If at any time following six (6) months after the Effective Date and prior to 3 years after the
Effective Date, the Company proposes to register shares of Common Stock under the Securities Act for distribution for its account pursuant to a primary underwritten offering (other than a registration statement on Form S-8 or Form S-4 or any
successor forms to such Forms) and the Company may register such offering on a form that would also permit the registration of the Registrable Stock, the Company shall, each such time, promptly give the Shareholder written notice of such
determination. Upon the written request of the Shareholder given within fifteen (15) days following such notice by the Company, subject to Section 4(B), the Company shall use its reasonable best efforts to cause to be registered
under the Act (and any related qualification or registration under blue sky laws) and included within any underwriting involved therein, all of the Registrable Stock that the Shareholder has requested be registered. Such written request may specify
all or a part of the Shareholder’s Registrable Stock. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 4 prior to the effectiveness of such registration whether or not the
Shareholder has elected to include securities in such registration. 
 (B) If lead underwriters of an underwritten primary registration
advise the Company that, in their good faith judgment, the number of securities requested to be included in such registration exceeds the number which can be sold in such offering without materially and adversely affecting the marketability of the
offering, then the Company will include in the Registration Statement relating to such registration (i) first, the securities the Company proposes to sell, and (ii) second, the Registrable Stock requested to be included in such
registration by the Stockholder(s) and any other stockholders of the Company (“Other Security Holders”) reduced on a pro rata basis, based on the amount of Acquired Securities owned by the requesting Stockholder(s) and, if
applicable, the securities owned by each such Other Security Holders. 
 5. Registration Procedures. Promptly after the Company is
required by the provisions of this Agreement to use its reasonable best efforts to effect the registration of any Registrable Stock under the Securities Act, the Company will, as expeditiously as possible: 
 (A) prepare and file with the SEC a Registration Statement with respect to such Registrable Stock and use its reasonable best efforts to cause such
Registration Statement to become effective (unless delayed under Section 3(D)); 
 (B) prepare and file with the SEC such
post-effective amendments and supplements to such Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement effective for such time as necessary to permit the Shareholder to
dispose of all of its Registrable Stock covered by the Registration Statement (or such other time as is provided herein) and to comply with the provisions of the 

  

 5 

 
Securities Act with respect to the sale or other disposition of all securities covered by such Registration Statement during such period in accordance with
the intended method or methods of disposition by the Shareholder thereof set forth in such Registration Statement; 
 (C) furnish to the
Shareholder such number of copies of such Registration Statement, each amendment and supplement thereto, the Prospectus included in the Registration Statement (including each preliminary Prospectus), and such other documents, as the Shareholder may
reasonably request in order to facilitate the public sale or other disposition of the securities owned by the Shareholder; 
 (D) to the
extent an exemption from registration or qualification does not exist, use reasonable best efforts to register or qualify the Acquired Securities covered by such Registration Statement under such other securities or blue sky laws of such
jurisdictions as the Shareholder shall reasonably request, and do any and all other acts and things which may be necessary under such securities or blue sky laws to enable the Shareholder to consummate the public sale or other disposition in such
jurisdiction of the Acquired Securities owned by the Shareholder covered by such Registration Statement; provided, however, that the Company shall not be required to (i) qualify to do business as a foreign corporation in any jurisdiction
wherein it would not otherwise be required to qualify but for this subparagraph or (ii) subject itself to general service of process or taxation in any such jurisdiction. 
 (E) use its reasonable best efforts to cause all such Acquired Securities covered by such Registration Statement to be listed on each securities exchange
or national market system on which securities of the same class are then listed; 
 (F) provide a transfer agent and registrar for
Registrable Stock not later than the effective date of such Registration Statement; and 
 (G) comply with all applicable rules and
regulations of the SEC, and make available to its security holders an earnings statement satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) no
later than 45 days after the end of any 12-month period (or 90 days after the end of any 12-month period if such period is a fiscal year) (or in each case within such shorter period of time as may be required by the SEC for filing the applicable
report with the SEC) (i) commencing at the end of any fiscal quarter in which Acquired Securities are sold to underwriters in an underwritten offering or (ii) if not sold to underwriters in such an offering, commencing on the first day of
the first fiscal quarter of the Company after the effective date of a Registration Statement, which earnings statement shall cover said 12-month period. 
 (H) The Stockholders agree that, upon receipt of written notice from the Company of a happening of any event or the existence of any facts that make any statement made in a Registration Statement or prospectus untrue
in any material respect or that require the making of any changes in a Registration Statement or prospectus so that it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under which they were made (in the case of any prospectus), not misleading, the Stockholders will forthwith discontinue disposition of such Acquired Securities covered by such
Registration Statement until they are 

  

 6 

 
advised in writing by the Company that the use of the applicable prospectus may be resumed, and have received copies of any additional or supplemental
filings that are incorporated or deemed to be incorporated by reference in such prospectus, and, if so directed by the Company, such Stockholders will deliver to the Company all copies of the prospectus covering such Acquired Securities current at
the time of receipt of such notice. 
 6. Stockholder Holdback. If the Company registers shares of Common Stock in connection with an
underwritten public offering by the Company, the Stockholders, if so required by the lead underwriters of such underwritten offering, agree not to effect any public sale or distribution of any of the Acquired Securities, including any sale pursuant
to Rule 144 promulgated under the Securities Act (other than as a part of such underwritten public offering), without the consent of the Company or such lead underwriters during the period commencing on a date specified by the lead underwriters,
such date not to exceed 10 days prior to the effective date of such Registration Statement, and ending on the earlier of (i) 90 days after the pricing of such offering, unless the lead underwriters for such offering otherwise agree, and
(ii) the abandonment of such offering. 
 7. Information. Shareholder hereby agrees to (a) to cooperate with the Company and
to promptly provide such information and assistance as the Company may reasonably request and as may be reasonably necessary to complete any Registration Statement or other required filing pursuant to this Agreement and (b) to the extent
required by the Securities Act, to deliver or cause delivery of the prospectus contained in any Registration Statement, and any amendment or supplement thereto, to any purchaser from such Stockholder of the Acquired Securities covered by the
Registration Statement. It shall be a condition precedent to the inclusion of the Registrable Stock of any Stockholders in a Registration Statement effected pursuant to this Agreement that such Stockholder shall execute such indemnities,
underwriting agreements, lockups and other documents as the Company or the managing underwriter shall reasonably request in order to satisfy the requirements applicable to such Registration Statement. 
 8. Expenses. To the fullest extent allowable under applicable state securities and blue sky laws, all expenses incurred in effecting the S-3
Registration Right, including without limitation, all registration and filing fees, printing expenses, fees and related expenses of counsel for the Company, expenses of any audits incident to or required by any such registration (other than audits
with respect to financial statements required to be delivered by Seller (as defined in the Purchase Agreement) under the Purchase Agreement) and expenses of complying with the securities or blue sky laws of any jurisdictions pursuant to
Subsection (D) of Section 5 hereof, shall be borne and paid by the Company; provided, however, that the Shareholder shall be responsible for all fees and any related expenses of counsel selected by the Shareholder and for all
brokerage or underwriting commissions and taxes of any kind (including without limitation transfer taxes) with respect to the disposition, sale, or transfer of the Registrable Stock. 
 9. Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this
Agreement.

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

postage prepaid, to each holder at its address as it appears in the Note Register, not less than ten days prior to such special record date. Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been
so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the
following clause (2) of this Section 2.03. 
 (2) The Company may make payment of any Defaulted Interest in any

of the payment of “Additional Interest” provided for in the Registration Rights Agreement to the extent that, in such context, Additional Interest is, was or would be payable in respect thereof pursuant to the provisions of the

the Company by the manual or facsimile signature of its Chief Executive Officer, President, Treasurer, Secretary or any of its Executive or Senior Vice Presidents.

 At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance with such Company Order shall authenticate and
deliver such Notes, without any further action by the Company hereunder.

certificate of authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, executed manually or by facsimile by an authorized officer of the Trustee (or an authenticating agent appointed by the Trustee as
provided by Section 17.11), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be
conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture. 
 In case any officer of the Company who shall have signed any of the Notes shall cease to be such officer before the Notes so signed shall
have been authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such officer of the
Company; and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the proper officers of the Company, although at the date of the execution of this Indenture any such person
was not such an officer. 
 Section 2.06. Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary.
(a) The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 5.02 being herein sometimes collectively
referred to as the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or
in any form capable of being converted into written form within a reasonable period of time. The Trustee is hereby appointed “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The
Company may appoint one or more co-registrars in accordance with Section 5.02.

entitled to receive, bearing registration numbers not contemporaneously outstanding.

registration of transfer or for exchange, repurchase or conversion shall (if so required by the Company, the Trustee, the Note Registrar or any co-registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in
form satisfactory to the Company and duly executed, by the Noteholder thereof or its attorney-in-fact duly authorized in writing. 
 No service charge shall be charged to the Noteholder for any exchange or registration of transfer of Notes, but the Company or the Trustee may require payment of a sum sufficient to cover any tax, assessments or other governmental charges
that may be imposed in connection therewith as a result of the name of the Noteholder of the new Notes issued upon such exchange or registration of transfer of Notes being different from the name of the Noteholder of the old Notes presented or
surrendered for such exchange or registration of transfer. 
 None of the Company, the Trustee, the Note Registrar or any
co-registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion or (ii) any Notes, or
a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 16 hereof. 
 All Notes
issued upon any registration of transfer or exchange of Notes in accordance with this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered
upon such registration of transfer or exchange. 
 (b) So long as the Notes are eligible for book-entry settlement with the
Depositary, unless otherwise required by law, all Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and
exchange of beneficial interests in a Global Note that does not involve the issuance of a definitive Note, shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions
on transfer set forth herein) and the procedures of the Depositary therefor. 
 (c) [Reserved.] 
 (d) Every Note that bears or is required under this Section 2.06(d) to bear the legend set forth in this Section 2.06(d)
(together with any Common Stock issued upon conversion of the Notes and required to bear the legend 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 the legend set forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the holder of each such Restricted Security, by such
holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in 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.

Section 2.06(e), if applicable) shall bear a legend in substantially the following form (unless such Notes have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that

COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 No transfer of any Note prior to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable
box on the Form of Assignment and Transfer has been checked. 
 Any Note (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 Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.06, be exchanged for a
new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.06(d). The Company shall notify the Trustee upon the occurrence of the Resale Restriction Termination Date

 Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.06(d)), a Global Note
may not be transferred as a whole or in part except (i) 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 and (ii) for transfers of portions of a Global Note in certificated form made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a
beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section. 
 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 Note. Initially, the Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for
Cede & Co. 
 If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable
to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency 

  

 17 

 
under the Exchange Act and a successor depositary is not appointed within 90 days or (iii) an Event of Default in respect of the Notes has occurred and
is continuing, upon the request of the beneficial owner of the Notes, the Company will execute, and the Trustee, upon receipt of an Officers’ Certificate and a Company Order for the authentication and delivery of Notes, will authenticate and
deliver Notes in definitive form to each such beneficial owner of the related Notes (or a portion thereof) in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, and upon delivery of the
Global Note to the Trustee such Global Note shall be canceled. 
 Definitive Notes issued in exchange for all or a part of the
Global Note 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 Notes to the Persons in whose names such definitive Notes are so registered. 
 At such time as all interests in a Global Note have been converted, canceled, repurchased or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures
and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for definitive Notes, converted, canceled, repurchased or transferred to a transferee who
receives definitive Notes therefor or any definitive Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the
Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase.

 None of the Company, the Trustee nor any agent of the Company or the Trustee will have any responsibility or liability for
any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 
 (e) Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon conversion of such Note
shall bear a legend in substantially the following form (unless the Note or such Common Stock has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be

of Notes that have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer 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): 
 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE 

  

 18 

 
OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST
HEREIN, THE ACQUIRER: 
 (1) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN
THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND 
 (2) AGREES FOR THE BENEFIT OF THE COMPANY THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE
HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THEREUNDER, AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT: 
 (A) TO THE NASDAQ STOCK MARKET, INC. (THE “COMPANY”) OR ANY SUBSIDIARY THEREOF, OR

TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND
APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 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). 
  

 19 

 (f) Any Note or Common Stock issued upon the conversion or exchange of a Note that 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 Notes 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 as promulgated under the Securities Act (or any successor rule) is amended to change the one-year holding period thereunder
(or the corresponding period under any successor rule), from and after receipt by the Trustee of the Officers’ Certificate and Opinion of Counsel provided for in this Section 2.06(g), (i) each reference in Section 2.06(d) to
“one year” and in the restrictive legend set forth in such paragraph to “ONE YEAR” shall be deemed for all purposes hereof to be references to such changed period, (ii) each reference in Section 2.06(e) to “one
year” and in the restrictive legend set forth in such paragraph to “ONE YEAR” shall be deemed for all purposes hereof to be references to such changed period and (iii) all corresponding references in the Notes (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 (or any successor rule) changing the holding period thereunder. 
 Section 2.07. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the
Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a number not contemporaneously outstanding, in exchange and
substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such
authenticating agent such security or indemnity as may be required by them to save each of them harmless 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 Note and of the ownership thereof. 
 The Trustee or such authenticating agent may authenticate any such substituted Note 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 substitute Note, 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 Note that has matured or is about to mature or has been tendered for repurchase upon a Fundamental Change or is
about 

  

 20 

 
to be converted into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, shall become mutilated or be destroyed,
lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, 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 Note), as
the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for
any loss, liability, cost or expense caused by or 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 Note and of the ownership thereof. 
 Every substitute Note
issued pursuant to the provisions of this Section 2.07 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note
shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent
permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall
preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their
surrender. 
 Section 2.08. Temporary Notes. Pending the preparation of Notes in certificated form, the Company may execute and
the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and
substantially in the form of the Notes in certificated form but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the
Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Notes in certificated form. Without unreasonable delay the Company will execute and
deliver to the Trustee or such authenticating agent Notes in certificated form (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) 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 Notes an equal aggregate principal amount of Notes in certificated form. Such exchange
shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Notes in
certificated form authenticated and delivered hereunder. 
 Section 2.09. Cancellation of Notes Paid, Etc. All Notes 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 Note Registrar or any Conversion Agent, be surrendered to the Trustee and promptly canceled by
it, or, if surrendered to the Trustee, shall be promptly canceled by it, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this 

  

 21 

 
Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary procedures and, after such disposition, shall deliver a certificate
of such disposition to the Company, at the Company’s written request. If the Company shall acquire any of the Notes, such acquisition shall not operate as satisfaction of the indebtedness represented by such Notes unless and until the same are
delivered to the Trustee for cancellation. 
 Section 2.10. CUSIP Numbers. The Company in issuing the Notes may use
“CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Noteholders as a convenience to holders of the Notes; provided, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company will promptly notify the Trustee
in writing of any change in the “CUSIP” numbers. 
 Section 2.11. Additional Notes; Repurchases. The Company may,
without the consent of the Noteholders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes hereunder with the same terms and with the same CUSIP number as the Notes initially issued hereunder in an unlimited
aggregate principal amount, which will form the same series with the Notes initially issued hereunder, provided that no such additional Notes may be issued unless they will be fungible with the original Notes for U.S. federal income tax and
securities law purposes. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion of Counsel to
cover such matters, in addition to those required by Section 17.05, as the Trustee shall reasonably request. The Company may also from time to time repurchase the Notes in open market purchases or negotiated transactions without prior notice to
Noteholders.

 Section 4.01. Satisfaction and Discharge. This Indenture shall
upon request of the Company contained in an Officers’ Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when
(a) (i) all Notes theretofore authenticated and delivered (other than (x) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.07 and (y) Notes for whose payment money
has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 5.04(d)) have been delivered to the Trustee for cancellation; and
(ii) the Company has deposited with the Trustee or delivered to Noteholders, as applicable, after the Notes have become due and payable, whether at the Maturity Date, any Fundamental Change Repurchase Date, upon conversion or otherwise, cash or
cash and shares of Common Stock, if any (solely to satisfy the Company’s Conversion Obligation, if applicable), sufficient to pay all of the outstanding Notes and all other sums due payable under this Indenture by the Company; and (b) the
Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.
Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 8.06 shall survive.

with an aggregate principal amount in excess of $1,000,000, at the application of such holder in writing to the Trustee and Paying Agent (if different from the Trustee) not later than the relevant Interest Record Date, accrued and unpaid interest
and Additional Interest, if any, on such holder’s Notes shall be paid by wire transfer in immediately available funds to such holder’s account in the United States, which application shall remain in effect until the Noteholder notifies the
Trustee and Paying Agent to the contrary; provided further that payment of accrued and unpaid interest and Additional Interest, if any, made to the Depositary shall be paid by wire transfer in immediately available funds in accordance with

the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office or the office or agency of the Trustee in the Borough of Manhattan, The City of New York. 
 The Company may also from time to time designate co-registrars one or more other offices or agencies where the Notes may be presented or

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

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

 Section 5.03. Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever
necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 8.10, a Trustee, so that there shall at all times be a Trustee hereunder. 
 Section 5.04. Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will
cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 5.04:

interest and Additional Interest, if any, on the Notes in trust for the benefit of the holders of the Notes;

Repurchase Price), if any, or accrued and unpaid interest or Additional Interest, if any, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action, provided that if such
deposit is made on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on such date. 
 (b) If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal of, premium (including the Fundamental Change Repurchase Price), if any, accrued and unpaid interest and Additional Interest, if any,

Interest, if any, so becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make any payment of the principal of, premium (including the Fundamental Change Repurchase
Price), if any, accrued and unpaid interest and Additional Interest, if any, on the Notes when the same shall become due and payable. 
 (c) Anything in this Section 5.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause
to be paid to the Trustee all sums held in trust by the Company or any Paying Agent hereunder as required by this Section 5.04, such sums to be held by the Trustee upon the trusts herein contained and upon such payment by the Company or any
Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability with respect to such sums.

 (d) Any money deposited with the Trustee or any Paying Agent, or then held by the
Company, in trust for the payment of the principal of or premium (including the Fundamental Change Repurchase Price), if any, accrued and unpaid interest and Additional Interest, if any, on any Note and remaining unclaimed for two years after such
principal, premium (including the Fundamental Change Repurchase Price), interest or Additional Interest has become due and payable shall be paid to the Company on request of the Company contained in an Officers’ Certificate, or (if then held by
the Company) shall be discharged from such trust; and the holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company
cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, The City of New York, New York, notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than thirty days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

force and effect its corporate existence. 
 Section 5.06. Rule 144A Information Requirement and Annual Reports. (a) At any
time the Company is not subject to Sections 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at such time, constitute “restricted
securities” within the meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and shall, upon written request, provide to any holder, beneficial owner or prospective purchaser of such Notes or any shares of Common
Stock issued upon conversion of such Notes, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A under the Securities
Act. The Company shall take such further action as any holder or beneficial owner of such Notes or such Common Stock may reasonably request to the extent required from time to time to enable such holder or beneficial holder to sell such Notes or
shares of Common Stock in accordance with Rule 144A under the Securities Act, as such rule may be amended from time to time. 
 (b) The Company shall deliver to the Trustee within three Business Days after the same is required to be filed with the Commission, copies of the quarterly and annual reports and of the information, documents and other reports, if any, that
the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, and, to the extent required by Section 17.08, the Company shall otherwise comply with the requirements of Trust Indenture Act section
314(a). Any such report, information or document that the Company files with the Commission through the Commission’s EDGAR database shall be deemed delivered to the Trustee for purposes of this Section 5.06(b) at the time of such filing
through the EDGAR database. 
 (c) Delivery of the reports, information and documents described in clause (b) above to
the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from 

  

 25 

 
information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to
conclusively rely exclusively on an Officers’ Certificate). 
 Section 5.07. Stay, Extension and Usury Laws. The Company
covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or
forgive the Company from paying all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture;
and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
 Section 5.08.
Compliance Certificate; Statements as to Defaults. 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, 2008) an Officers’

thereof. 
 In addition, the Company shall deliver to the Trustee, as soon as possible, and in any event within thirty days
after the Company becomes aware of the occurrence of any Event of Default or Default, an Officers’ Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company proposes to take with
respect thereto.

Registration Rights Agreement, the Company shall deliver to the Trustee an Officers’ Certificate to that effect stating (a) the amount of such Additional Interest that is payable and (b) the date on which such interest is payable.
Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid Additional Interest directly
to the Persons entitled to them, the Company shall deliver to the Trustee an Officers’ Certificate setting forth the particulars of such payment. 
 Section 5.10. Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to
carry out more effectively the purposes of this Indenture.

 (g) default by the
Company or any Subsidiary of the Company in the payment of the principal or interest on any mortgage, agreement or other instrument under which there may be outstanding, or by which there may be secured or evidenced, any debt for money borrowed in

 (i) the Company or any Subsidiary of the Company that is a “significant subsidiary” (as defined in Regulation S-X under the

other proceeding shall remain undismissed and unstayed for a period of thirty consecutive days. 
 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(i) or Section 7.01(j) with respect to the Company (and not solely with
respect to a “significant subsidiary” (as defined in Regulation S-X under the Exchange Act) of the Company, or a group of Subsidiaries of the Company that in aggregate would constitute a “significant subsidiary” of the Company),
unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 9.04, by
notice in writing to the Company (and to the Trustee if given by Noteholders), may declare 100% of the principal of and premium, if any, and accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on all the Notes to be due
and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding. If an Event of Default
specified in Section 7.01(i) or Section 7.01(j) with respect to the Company (and not solely with respect to a “significant subsidiary” (as defined in Regulation S-X under the Exchange Act) of the Company, or a group of
Subsidiaries of the Company that in aggregate would constitute a “significant subsidiary” of the Company) occurs and is continuing, the principal of all the Notes and accrued and unpaid interest and accrued and unpaid Additional Interest,
if any, shall be immediately due and payable. This provision, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment
of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest and accrued and unpaid Additional Interest, if
any, upon all Notes and the principal of and premium, if any, on any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest and accrued and unpaid Additional
Interest, 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 borne by the Notes at such time) and amounts due to the Trustee pursuant to Section 8.06,
and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all Events of Defaults under this Indenture, other than the nonpayment of principal of and premium, if any, and
accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on Notes that shall have become due solely by such 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 Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes (other than a Default or an Event of Default
resulting from a failure to repurchase any Notes when required upon a Fundamental Change or a failure to deliver, upon 

  

 29 

 
conversion, cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, due upon conversion) and rescind and annul such
declaration and its consequences (other than a declaration or consequences, as the case may be, resulting from a failure to repurchase any Notes when required upon a Fundamental Change or a failure to deliver, upon conversion, cash, shares of Common
Stock or a combination of cash and shares of Common Stock, as applicable, due upon conversion) and such Default (other than a Default resulting from a failure to repurchase any Notes when required upon a Fundamental Change or a failure to deliver,
upon conversion, cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, due upon conversion) shall cease to exist, and any Event of Default arising therefrom (other than a Default resulting from a failure to
repurchase any Notes when required upon a Fundamental Change or a failure to deliver, upon conversion, cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, due upon conversion) shall be deemed to have been
cured for every purpose of this Indenture; 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. 
 Notwithstanding anything in this Indenture or in the Notes to the contrary, for the first 360 days immediately following any violation of
any obligations the Company may be deemed to have pursuant to (1) Section 314(a)(1) of the Trust Indenture Act, or (2) Section 5.06(b), and the continuation thereof, the sole remedy for any such violation shall be the accrual of
additional interest on the Notes at a rate per year equal to 0.50% of the outstanding principal amount of the Notes (“Supplementary Interest”), payable semi-annually at the same time and in the same manner as regular interest on the
Notes pursuant to Section 2.03 and Section 5.01. In no event shall Supplementary Interest accrue at a rate per year in excess of 0.50%, regardless of the number of events or circumstances giving rise to the requirement to pay Supplementary
Interest. In addition to the accrual of Supplementary Interest, on and after the 360th day, any violation of any obligations the Company may be deemed to have pursuant to (1) Section 314(a)(1) of the Trust Indenture Act or
(2) Section 5.06(b), either the Trustee or the Noteholders of not less than 25% in aggregate principal amount of the Notes then outstanding may declare the principal amount of the Notes and any accrued and unpaid interest, including any
Additional Interest, through the date of such declaration, to be immediately due and payable. Whenever in this Indenture there is mentioned, in any context, the payment of interest on, or in respect of, any Note, such mention shall be deemed to
include mention of the payment of “Supplementary Interest” provided for in this paragraph to the extent that, in such context, Supplementary Interest is, was or would be payable in respect thereof pursuant to the provisions of this
paragraph, and express mention of the payment of Supplementary Interest (if applicable) in any provisions hereof shall not be construed as excluding Supplementary Interest in those provisions hereof where such express mention is not made.

 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 Noteholders, 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 Noteholders, and the Trustee shall continue as though no such proceeding had been
instituted.

 Section 7.02. Payments of Notes on Default; Suit Therefor. If an Event of Default described
in clause (a) or (b) of Section 7.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to it, for the benefit of the holders of the Notes, the whole amount then due and payable on the Notes for principal,
premium, if any, and interest and Additional Interest, if any, with interest on any overdue principal, premium, if any, interest and Additional Interest, if any, at the rate borne by the Notes at such time, and, in addition thereto, such further
amount as shall be sufficient to cover any amounts due to the Trustee under Section 8.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or
decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated. 
 In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under title 11 of the United States Code, or any other applicable law, or
in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other
obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the
Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 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 and accrued and unpaid Additional Interest, if any, in respect of the Notes, 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 Noteholders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their
property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due the Trustee under Section 8.06; and any receiver, assignee or trustee
in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Noteholders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the
making of such payments directly to the Noteholders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including 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 that the holders of the Notes may be entitled to receive in such proceedings, whether in
liquidation or under any plan of reorganization or arrangement or otherwise. 
  

 31 

 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent
to or accept or adopt on behalf of any Noteholder any plan of reorganization, arrangement, adjustment or composition affecting the Noteholder or the rights of any Noteholder thereof, or to authorize the Trustee to vote in respect of the claim of any
Noteholder in any such proceeding. 
 All rights of action and of asserting claims under this Indenture, or under any of the
Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the
holders of the Notes. 
 In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any
provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the holders of the Notes, and it shall not be necessary to make any holders of the Notes parties to any such proceedings. 
 Section 7.03. Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 7 with respect to the
Notes shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender
thereof, if fully paid: 
 First, to the payment of all amounts due the Trustee under Section 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,
including Additional Interest, if any, in default in the order of the date due 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 at such time, such payments to be made ratably to the Persons entitled thereto; 
 Third, in case the
principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount including the payment of the Fundamental Change Repurchase Price and the cash component of the Conversion
Obligation, if any, then owing and unpaid upon the Notes for principal and premium, if any, and interest, including Additional Interest, if any, with interest on the overdue principal and premium, if any, and (to the extent that such interest has
been collected by the Trustee) upon overdue installments of interest at the rate borne by the Notes at such time, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of
such principal and premium, if any, and interest without preference or priority of principal and premium, if any, over interest, or of interest over principal and premium, if any, or of any installment of interest over any other installment of
interest, or of any Note over any other Note, ratably to the aggregate of such principal and premium, if any, and accrued and unpaid interest; and 
  

 32 

 Fourth, to the payment of the remainder, if any, to the Company. 
 Section 7.04. Proceedings by Noteholders. No holder of any Note 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 Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such security or indemnity reasonably satisfactory
to it against any loss, liability or expense to be incurred therein or thereby, and the Trustee for sixty 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 that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the holders of a majority in principal amount of the Notes outstanding within such sixty-day period
pursuant to Section 7.07; it being understood and intended, and being expressly covenanted by the taker and holder of every Note with every other taker and holder and the Trustee that no one or more Noteholders shall have any right in any
manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Noteholder, 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 Noteholders (except as otherwise provided herein). For the protection and enforcement of this Section 7.04, each and every
Noteholder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 
 Notwithstanding any
other provision of this Indenture and any provision of any Note, the right of any Noteholder to receive payment of the principal of and premium, if any (including the Fundamental Change Repurchase Price upon repurchase pursuant to
Section 16.02), and accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the
enforcement of any such payment on or after such respective dates against the Company shall not be impaired or affected without the consent of such Noteholder. 
 Anything in this Indenture or the Notes to the contrary notwithstanding, the holder of any Note, without the consent of either the Trustee
or the holder of any other Note, in its own behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, its rights of conversion as provided herein. 
 Section 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.

  

 33 

 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 Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to
the Trustee or the holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any holder of any of
the Notes to exercise any right or power accruing upon any Default or Event of Default 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 Noteholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders. 
 Section 7.07. Direction of Proceedings and Waiver of Defaults by Majority of Noteholders. The holders of a majority in aggregate principal
amount of the Notes at the time outstanding determined in accordance with Section 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 Notes; 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 Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other holder or that would involve the Trustee in personal liability.
The holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 9.04 may on behalf of the holders of all of the Notes waive any past Default or Event of Default hereunder and
its consequences except (i) a default in the payment of premium, accrued and unpaid interest or accrued and unpaid Additional Interest, if any, on, or the principal (including any Fundamental Change Repurchase Price) of, the Notes when due that
has not been cured pursuant to the provisions of Section 7.01, (ii) a failure by the Company to deliver cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, upon conversion of the Notes or
(iii) a default in respect of a covenant or provision hereof which under Article 11 cannot be modified or amended without the consent of each holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the holders
of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default
hereunder shall have been waived as permitted by this Section 7.07, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend
to any subsequent or other Default or Event of Default or impair any right consequent thereon. 
 Section 7.08. Notice of
Defaults. The Trustee shall, within ninety days after the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, mail to all Noteholders as the names and addresses of such holders appear upon the Note
Register, notice of all Defaults known to a Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice; and provided that, except in the case of a Default in the payment of the principal of, or
premium, if any, accrued and unpaid interest or accrued and unpaid Additional Interest, if any, on any of the Notes, including without limiting the generality of the foregoing any Default in the payment of any Fundamental Change Repurchase Price,
then in any such event the Trustee shall be protected in withholding such notice if and so long as a committee of Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Noteholders.

  

 34 

 Section 7.09. Undertaking to Pay Costs. All parties to this Indenture agree, and each holder
of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action
taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and
expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 7.09 (to the extent permitted by law)
shall not apply to any suit instituted by the Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with
Section 9.04, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or premium, if any, accrued and unpaid interest or accrued and unpaid Additional Interest, if any, on any Note (including, but not
limited to, the Fundamental Change Repurchase Price with respect to the Notes being repurchased as provided in this Indenture) on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert
any Note in accordance with the provisions of Article 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 that 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; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the
rights or powers under this Indenture at the request or direction of any of the holders unless such holders have offered to the Trustee reasonable indemnity or security against the costs, expenses and liabilities that might be incurred by it in
compliance with such request or direction. 
 No provision of this Indenture shall be construed to relieve the Trustee from
liability for its own grossly negligent action, its own grossly 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 that 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 

  

 35 

 
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 that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this
Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein); 
 (b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was grossly 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 Notes at the time outstanding determined as provided in Section 9.04 relating to the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; 
 (d)
whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section; 
 (e) the Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other
matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-registrar with respect to the Notes; 
 (f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive
such notice as reason to act as if no such event occurred, 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, and 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 investment prior to its maturity date or the failure of the party directing such investments prior to its maturity
date 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, Note 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, Note 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. 
  

 36 

 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 Board Resolution 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 Noteholders pursuant to the provisions of this Indenture, unless such Noteholders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities that 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 at the expense
of the Company and shall incur no liability of any kind by reason of such inquiry or investigation; 
 (f) the Trustee may
execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, custodians, nominees or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any
agent, custodian, nominee or attorney appointed by it with due care hereunder; and 
 (g) the permissive rights of the Trustee
enumerated herein shall not be construed as duties. 
 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 any such loss or damage caused by the
Trustee’s willful misconduct or gross negligence. The Trustee 

  

 37 

 
shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, 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 Notes. 
 Section 8.03. No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate
of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes.
The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. 
 Section 8.04. Trustee, Paying Agents, Conversion Agents or Registrar May Own Notes. The Trustee, any Paying Agent, any Conversion Agent or
Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not the Trustee, Paying Agent, Conversion Agent or Note Registrar. 
 Section 8.05. Monies to Be Held in Trust. 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 and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture in any capacity thereunder (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 shall have been caused by its gross 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, claim, damage, liability or expense
incurred without gross 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 senior claim to which the Notes are hereby made subordinate on all money or property held or collected by the
Trustee, except, subject to the effect of Section 7.03, funds held in trust herewith for the benefit of the holders of particular Notes. 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 Notes may be so subordinated). The obligation of the Company under this Section 8.06 shall survive the satisfaction and discharge of 

  

 38 

 
this Indenture and the earlier resignation or removal or the Trustee. The Company need not pay for any settlement made without its consent, which consent
shall not be unreasonably withheld. The indemnification provided in this Section 8.06 shall extend to the officers, directors, agents and employees of the Trustee. 
 Without prejudice to any other rights available to the Trustee under applicable law, 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(i) or Section 7.01(j) 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 gross 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 gross 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. 
 Section 8.08.
Conflicting Interests of Trustee. After qualification of this Indenture 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
(a) eliminate such interest within ninety days, (b) apply to the Commission for permission to continue as Trustee or (c) 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 Noteholders at their addresses as they shall appear on the Note 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 within sixty days after the mailing of such notice of resignation to the Noteholders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Noteholders, petition any court of competent jurisdiction for the
appointment of a successor trustee, or any Noteholder who has been a bona fide holder of a Note or Notes 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. 
  

 39 

 (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 Noteholder who has been a bona fide holder of a Note or Notes for at least six months, or 
 (ii) the Trustee shall cease
to be eligible in accordance with the provisions of Section 8.09 and shall fail to resign after written request therefor by the Company or by any such Noteholder, or 
 (iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its
property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
 then, in any such case, the 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 Noteholder who has been a bona fide
holder of a Note or Notes for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 
 (c) The holders of a majority in aggregate principal amount of the Notes at the time outstanding, as determined in accordance with Section 9.04, may at any time remove the Trustee and nominate a successor trustee that shall be deemed
appointed as successor trustee unless within ten days after notice to the Company of such nomination the Company objects thereto, in which case the Trustee so removed or any Noteholder, 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. 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 
  

 40 

 
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 rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for the
benefit of holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 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 successor 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 Noteholders at their addresses as
they shall appear on the Note Register. If the Company fails to mail such notice within ten 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 or other entity 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 or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or other entity 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 Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by
such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may
authenticate such Notes 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 Notes 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 Notes in the name of any predecessor 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 Notes), 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). 
  

 41 

 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 Notes under this Indenture) 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 Business Days after the date any officer that the
Company has indicated to the Trustee should receive such application 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 accordance with this Indenture in response to such application specifying the action to be taken or omitted. 
 ARTICLE 9 
 CONCERNING THE NOTEHOLDERS 
 Section 9.01. Action by Noteholders. Whenever in this Indenture it is provided that the holders of a specified percentage in aggregate
principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the holders of
such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in writing, or (b) by the record of the
Noteholders voting in favor thereof at any meeting of Noteholders 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
Noteholders. Whenever the Company or the Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee may fix, but shall not be required to, in advance of such solicitation, a date as the record date for
determining Noteholders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action. 
 Section 9.02. Proof of Execution by Noteholders. Subject to the provisions of Section 8.01, Section 8.02 and Section 10.05,
proof of the execution of any instrument by a Noteholder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the
Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. The record of any Noteholders’ 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 Note Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of
ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of, premium, if any, and (subject to Section 2.03) accrued and unpaid
interest and accrued and unpaid Additional Interest, if 

  

 42 

 
any, on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion
Agent nor any Note Registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon its order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and
discharge the liability for monies payable upon any such Note. Notwithstanding anything to the contrary in this Indenture or the Notes following an Event of Default, any holder of a beneficial interest in a Global Note may directly enforce against
the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the
provisions of this Indenture. 
 Section 9.04. Company-Owned Notes Disregarded. In determining whether the holders of the
requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company or by any Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, consent, waiver or other action only Notes that a Responsible Officer knows are so owned shall be so disregarded. Notes 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 so act with respect to such Notes and that the pledgee is not the Company or a Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee,
the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to
Section 8.01, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such
determination. 
 Section 9.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the
evidencing to the Trustee, as provided in Section 9.01, of the taking of any action by the holders of the percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action, any holder of a Note
that is shown by the evidence to be included in the Notes the holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 9.02,
revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the holder of any Note shall be conclusive and binding upon such holder and upon all future holders and owners of such Note and of any Notes issued in
exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer
thereof.

 Any record so signed and verified shall be conclusive evidence of the matters therein stated. 
 Section 10.07. No Delay of Rights by Meeting. Nothing contained in this Article 10 shall be deemed or construed to authorize or permit, by
reason of any call of a meeting of Noteholders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to the Trustee or to the Noteholders

 Section 12.01. Company May Consolidate, Etc. on Certain Terms. 
 Subject to the provisions of Section 12.02, the Company shall not consolidate with, merge with or into, or convey, transfer or lease

(if not the Company) shall expressly assume, by supplemental indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of the Company under the Notes, this Indenture and, to the extent that it is
otherwise still operative, the Registration Rights Agreement; and 
  

 48 

 (b) immediately after giving effect to such transaction, no Default or Event of Default

assets, if held by the Company instead of such Subsidiaries, would constitute the properties and assets of the Company substantially as an entirety on a consolidated basis, shall be deemed to be the transfer of the properties and assets of the
Company substantially as an entirety to another Person.

the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company, such Successor Company 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 Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have
been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company 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 be authenticated and delivered, any Notes that previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall
cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of
this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, conveyance or transfer (but not in the case of a lease), the Person named as the “Company” in
the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 12 may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such
Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture. 
 In case of any such consolidation, merger, conveyance, transfer or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate. 
 Section 12.03. Opinion of Counsel to Be Given Trustee. No merger, 

  

 49 

 
consolidation, conveyance, transfer or lease shall be effective unless the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as
conclusive evidence that any such consolidation, merger, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the
provisions of this Article 12.

present or future, of the Company or of any successor corporation or entity, either directly or through the Company or any successor corporation or entity, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issue of the Notes.

period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes for each day of such Measurement Period was less than 98% of the product of the then-applicable Conversion Rate on such Trading Day
and the Last Reported Sale Price of the Common Stock on such Trading Day. The Trading Prices shall be determined by the Trustee pursuant to this clause and the definition of Trading Price set forth in this 

  

 50 

 
Indenture. The Company shall provide written notice to the Trustee of the three independent nationally recognized securities dealers selected by the Company
pursuant to the definition of Trading Price, along with appropriate contact information for each. The Trustee shall have no obligation to determine the Trading Price of the Notes unless requested by the Company, and the Company shall have no
obligation to make such request unless a Noteholder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of the Notes would be less than 98% of the product of the then-applicable Conversion Rate and the
Last Reported Sale Price of the Common Stock at such time, at which time the Company shall instruct the Trustee to determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price
per Note is greater than or equal to 98% of the product of the then-applicable Conversion Rate and the Last Reported Sale Price of the Common Stock on such Trading Day. If the Company does not, when obligated to, instruct the Trustee to determine
the Trading Price of the Notes as provided in the preceding sentence, or if the Company gives such instruction to the Trustee, and the Trustee fails to make such determination, then the Trading Price per $1,000 principal amount of Notes will be
deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the then-applicable Conversion Rate. If the Trading Price condition set forth above has been met, the Company shall so notify the Noteholders, the
Trustee and the Conversion Agent. If, at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than 98% of the product of the then-applicable Conversion Rate and
the Last Reported Sale Price of the Common Stock on such Trading Day, the Company shall so notify the holders of the Notes, the Trustee and the Conversion Agent. In either case, the Company shall promptly publish a notice indicating that the Trading
Price condition set forth above has been met or, at any time after the Trading Price condition set forth above has been met, that the Trading Price per $1,000 principal amount of Notes is greater than 98% of the product of the then-applicable
Conversion Rate and the Last Reported Sale Price of the Common Stock on the relevant Trading Day, as the case may be, in a newspaper of general circulation in The City of New York or publish such information on its website or through such other
public medium as the Company may use at that time. 
 (ii) In the event that the Company elects to: 
 (A) distribute to all or substantially all holders of its Common Stock rights, options or warrants entitling them, for a period of not
more than sixty calendar days from the declaration date of such distribution, to subscribe for or purchase its Common Stock, at a price per share less than the Last Reported Sale Price of the Common Stock for the Trading Day immediately preceding
the declaration date for such distribution; or 
 (B) distribute to all or substantially all holders of its Common Stock the
Company’s assets, debt securities, or rights to purchase securities of the Company, which distribution has a per share value (as determined by the Board of Directors) exceeding 10% of the Last Reported Sale Price of the Common Stock on the
Trading Day immediately preceding the date of declaration for such distribution, 

  

 51 

 
then, in each case, the Company shall notify all holders of the Notes, the Trustee and the Conversion Agent not less than thirty-five Business Days prior to
the Ex-Dividend Date for such distribution. Once the Company has given such notice, the Notes may be surrendered for conversion at any time until the earlier of (1) the close of business on the Business Day immediately prior to such Ex-Dividend
Date and (2) the Company’s announcement that such distribution will not take place, even if the Notes are not otherwise convertible at such time. 
 (iii) In the event of a Fundamental Change, a Noteholder may surrender Notes for conversion at any time from and after the thirty-fifth Business Day prior to the anticipated effective date of such Fundamental Change
until the Business Day immediately preceding the Fundamental Change Repurchase Date corresponding to such Fundamental Change. The Company shall give notice of the anticipated effective date of any Fundamental Change as promptly as practicable after
the Company first determines the anticipated effective date of such Fundamental Change, but in any event at least thirty-five Business Days prior to such anticipated effective date. 
 (iv) The Notes may be surrendered for conversion in any Fiscal Quarter after the Fiscal Quarter ending June 30, 2008, and only during
such Fiscal Quarter, if the Last Reported Sale Price of the Common Stock for at least twenty Trading Days in a period of thirty consecutive Trading Days ending on the last Trading Day of the immediately preceding Fiscal Quarter is equal to or more
than 130% of the then-applicable Conversion Price on the last day of such preceding Fiscal Quarter (such price, the “Conversion Trigger Price”). The Conversion Agent, on behalf of the Company, shall determine at the beginning of
each Fiscal Quarter commencing after June 30, 2008 whether the Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify the Company and the Trustee. 
 Section 15.02. Conversion Procedure. 
 (a) [Reserved]. 
 (b) Subject to this Section 15.02, upon any conversion of any Note,
the Company shall deliver to converting Noteholders, in respect of each $1,000 principal amount of Notes being converted, solely cash, solely shares of Common Stock or a combination of cash and Common Stock (the “Settlement
Amount”), at its election, as set forth in this Section 15.02. 
 (i) All conversions after May 15, 2013
will be settled using the same Settlement Method. 
 (ii) Prior to May 15, 2013, the Company will elect (or be deemed to
have elected) the same Settlement Method for all conversions occurring on any given Conversion Date. Except for any conversions that occur on or after May 15, 2013, the Company need not elect the same Settlement Method with respect to
conversions that occur on different Trading Days. 
 (iii) If, in respect of any Conversion Date (or the period beginning on,
but excluding, May 15, 2013 and ending on, and including, the Business Day immediately preceding the Maturity Date, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant
Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company, through the Trustee, shall deliver such Settlement Notice to 

  

 52 

 
converting Noteholders no later than the second Trading Day immediately following the relevant Conversion Date. Such Settlement Notice shall specify whether
the Company shall satisfy its Conversion Obligation by (A) delivering solely shares of Common Stock, (B) paying solely cash or (C) paying and delivering, as the case may be, a combination of cash and shares of Common Stock. In the
case of an election to pay and deliver, as the case may be, a combination of cash and shares of Common Stock, the relevant Settlement Notice shall indicate the Specified Dollar Amount. If the Company does not deliver a Settlement Notice, the Company
will be deemed to have elected to deliver a combination of cash and shares of Common Stock in respect of its Conversion Obligation, and the Specified Dollar Amount shall be deemed to be equal to $1,000. If the Company delivers a Settlement Notice
electing to pay and deliver, as the case may be, a combination of cash and shares of Common Stock in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount in such Settlement Notice, the Specified Dollar Amount shall be
deemed to be equal to $1,000. 
 (iv) The Settlement Amount in respect of any conversion of Notes shall be computed as
follows: 
 (A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by delivering solely
Common Stock, the Company will deliver to the converting Noteholder a number of shares of Common Stock equal to (1) the aggregate principal amount of Notes to be converted, divided by $1,000, multiplied by (2) the
then-applicable Conversion Rate; 
 (B) if the Company elects to satisfy its Conversion Obligation in respect of such
conversion by paying solely cash, the Company shall pay to the converting Noteholder cash in an amount per $1,000 principal amount of Notes being converted equal to the sum of the Daily Conversion Values for each of the thirty consecutive Trading
Days during the related Cash Settlement Averaging Period; and 
 (C) if the Company elects to satisfy its Conversion
Obligation in respect of such conversion by paying and delivering, as the case may be, a combination of cash and shares of Common Stock, if any, the Company shall pay and deliver, as the case may be, in respect of each $1,000 principal amount of
Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the thirty consecutive Trading Days during the related Cash Settlement Averaging Period. 
 (v) The Company will also deliver to each converting Noteholder cash in lieu of fractional shares of Common Stock as set forth pursuant to
clause (l) below. 
 (vi) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable)
shall be determined by the Company promptly following the last day of the Cash Settlement Averaging Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash
deliverable 

  

 53 

 
in lieu of fractional shares (if any), the Company shall notify the Trustee and the Conversion Agent of the Daily Settlement Amounts or the Daily Conversion
Values, as the case may be, and the amount of cash deliverable in lieu of fractional shares of Common Stock. The Trustee and the Conversion Agents shall have no responsibility for any such determination. 
 (c) [Reserved.] 
 (d) Before any holder of a Note shall be entitled to convert the same as set forth above, such holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay
funds equal to interest payable on the next Interest Payment Date to which such holder is not entitled as set forth in Section 15.02(j) and, if required, all transfer or similar taxes, if any, and (ii) in the case of a Note issued in
certificated form, (1) complete and manually sign and deliver an irrevocable notice to the Conversion Agent in the form on the reverse of such certificated Note (or a facsimile thereof) (Exhibit B hereto) (a “Notice of
Conversion”) at the office of the Conversion Agent and shall state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such holder wishes the certificate or certificates for any
shares of Common Stock, if any, to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer
documents), at the office of the Conversion Agent, (3) if required, pay funds equal to interest payable on the next Interest Payment Date to which such holder is not entitled as set forth in Section 15.02(j), (4) if required, furnish
appropriate endorsements and transfer documents, and (5) if required, pay all transfer or similar taxes, if any as set forth in Section 15.02(g). The Trustee (and if different, the relevant Conversion Agent) shall notify the Company of any
conversion pursuant to this Article 15 on the date of such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a holder thereof if such holder has also delivered a Fundamental Change Repurchase Notice to the Company
in respect of such Notes and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 16.03. 
 If more than one Note shall be surrendered for conversion at one time by the same holder, the Conversion Obligation with respect to such Notes, if any, that shall be payable upon conversion shall be computed on the basis of the aggregate
principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 
 (e) A Note
shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”) that the holder has complied with the requirements set forth in clause (d). The Company shall pay and deliver, as
the case may be, the cash and/or shares of Common Stock due in respect of it Conversion Obligation on the third Trading Day immediately following the relevant Conversion Date, if the Company elects to satisfy the related Conversion Obligation solely
in shares of Common Stock, or by the third Trading Day immediately following the last Trading Day of the Cash Settlement Averaging Period, in the case of any other Settlement Method. If any shares of Common Stock are due to converting Noteholders,
the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Noteholder, or such Noteholder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of
Common Stock to which such Noteholder shall be entitled in satisfaction of such Conversion Obligation. 
  

 54 

 (f) In case any Note 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 Note so surrendered, without charge to such holder, a new Note or Notes in authorized denominations in an aggregate principal amount equal to
the unconverted portion of the surrendered Note. 
 (g) If a holder submits a Note for conversion, the Company shall pay all
stamp and other duties, if any, that 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 Common Stock, if any, upon the conversion. However, the
holder shall pay any such tax that is due because the holder requests any shares of Common Stock to be issued in a name other than the holder’s name. The Conversion Agent may refuse to deliver the certificates representing the shares of Common
Stock being issued in a name other than the holder’s name until the Trustee receives a sum sufficient to pay any tax that 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. 
 (h) Except as provided in Section 15.04, no adjustment shall be
made for dividends on any shares issued upon the conversion of any Note as provided in this Article. 
 (i) Upon the
conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the
Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee. 
 (j) Upon
conversion, a Noteholder shall not receive any separate cash payment for accrued and unpaid interest and Additional Interest, if any, except as set forth below. The Company’s settlement of the Conversion Obligations as described above shall be
deemed to satisfy its obligation to pay the principal amount of the Note and accrued and unpaid interest and Additional Interest, if any, to, but not including, the Conversion Date. As a result, accrued and unpaid interest and Additional Interest,
if any, to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the preceding sentence, if Notes are converted after the close of business on a Interest Record
Date, holders of such Notes as of the close of business on the Interest Record Date will receive the interest and Additional Interest, if any, payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes
surrendered for conversion during the period from the close of business on any Interest 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 and
Additional Interest, if any, payable on the Notes so converted; provided, however, that no such payment shall be required (1) if the Company has specified a Fundamental Change Repurchase Date that is after a Interest Record Date
but on or prior to the corresponding Interest Payment Date, (2) to the extent of any Defaulted Interest, if any, existing at the time of conversion with respect to such Note or (3) if the Notes are surrendered for conversion after the
close of business on the Interest Record Date immediately preceding the Maturity Date. Except as described above, no payment or adjustment will be made for accrued and unpaid interest and Additional Interest, if any, on converted Notes. 

 

 55 

 (k) The Person in whose name the certificate for any shares of Common Stock delivered
upon conversion is registered shall be treated as a stockholder of record as of the close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation solely in shares of Common Stock) or the last
Trading Day of the related Cash Settlement Averaging Period (in the case of any other Settlement Method), as the case may be; provided, however, if such Conversion Date or such last Trading Day of the Cash Settlement Averaging Period
occurs on any date when the stock transfer books of the Company shall be closed, such occurrence shall not be effective to constitute the Person or Persons entitled to receive any such shares of Common Stock due upon conversion as the record holder
or holders of such shares of Common Stock on such date, but such occurrence shall be effective to constitute the Person or Persons entitled to receive such shares of 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. Upon conversion of Notes, such Person shall no longer be a Noteholder. 
 (l) For each Note surrendered for conversion, if the Company has elected to deliver a combination of cash and shares of Common Stock in respect of its Conversion Obligation, the number of full shares that shall be
issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the applicable Cash Settlement Averaging Period and any fractional shares remaining after such computation shall be paid in cash. If more
than one Note shall be surrendered for conversion at one time by the same holder, the number of full shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Notes (or specified
portions thereof) so surrendered. The Company shall not issue fractional shares of Common Stock upon conversion of Notes. Instead, the Company shall pay cash in lieu of fractional shares based on the Daily VWAP on the relevant Conversion Date (if
the Company elects to satisfy its Conversion Obligation solely in shares of Common Stock) or based on the Daily VWAP on the last Trading Day of the relevant Cash Settlement Averaging Period (in the case of any other Settlement Method). 

Section 15.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes.
(a) Notwithstanding anything herein to the contrary, the Conversion Rate applicable to each Note that is surrendered for conversion, in accordance with this Article 15, at any time from, and including, the effective date of a Make-Whole
Fundamental Change until, and including, the close of business on the Business Day immediately prior to the related Fundamental Change Repurchase Date corresponding to such Make-Whole Fundamental Change, shall be increased to an amount equal to the
Conversion Rate that would, but for this Section 15.03, otherwise apply to such Note pursuant to this Article 15, plus an amount equal to the Make-Whole Conversion Rate Adjustment. 
 As used herein, “Make-Whole Conversion Rate Adjustment” shall mean, with respect to a Make-Whole Fundamental Change, the
amount set forth in the following table that corresponds to the effective date of such Make-Whole Fundamental Change (the “Effective Date”) and the Stock Price for such Make-Whole Fundamental Change, all as determined by the
Company:

 provided, however, that: 
 (i) if the actual Stock Price of such Make-Whole Fundamental Change is between two Stock Prices listed in the table above under the column
titled “Stock Price,” or if the actual Effective Date of such Make-Whole Fundamental Change is between two Effective Dates listed in the table above in the row immediately below the title “Effective Date,” then the Make-Whole
Conversion Rate Adjustment for such Make-Whole Fundamental Change shall be determined by the Company by linear interpolation between the Make-Whole Conversion Rate Adjustment set forth for such higher and lower Stock Prices, or for such earlier and
later Effective Dates based on a 365 day year, as applicable; 
 (ii) if the actual Stock Price of such Make-Whole Fundamental
Change is greater than $105.00 per share (subject to adjustment in the same manner as the Stock Price as provided in clause (iii) below), or if the actual Stock Price of such Make-Whole Fundamental Change is less than $39.10 per share (subject
to adjustment in the same manner as the Stock Price as provided in clause (iii) below), then the Make-Whole Conversion Rate Adjustment shall be equal to zero and this Section 15.03 shall not require the Company to increase the Conversion
Rate with respect to such Make-Whole Fundamental Change; 
 (iii) if an event occurs that requires, pursuant to this Article
15 (other than solely pursuant to this Section 15.03), an adjustment to the Conversion Rate, then, on the date and at the time such adjustment is so required to be made, each price set forth in the table above under the column titled
“Stock Price” shall be deemed to be adjusted so that such Stock Price, at and after such time, shall be equal to the product of (1) such Stock Price as in effect immediately before such adjustment to such Stock Price and (2) a
fraction whose numerator is the Conversion Rate in effect immediately before such adjustment to the Conversion Rate and whose denominator is the Conversion Rate to be in effect, in accordance with this Article 15, immediately after such adjustment
to the Conversion Rate; 
 (iv) [Reserved.]; 
 (v) each Make-Whole Conversion Rate Adjustment set forth in the table above shall be adjusted in the same manner in which, and for the
same events for which, the Conversion Rate is to be adjusted pursuant to Section 15.04; and 
  

 57 

 (vi) in no event will the total number of shares of Common Stock issuable upon conversion
of the Notes exceed 25.5754 per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 15.04. 
 (b) As soon as practicable after the Company determines the anticipated Effective Date of any proposed Make-Whole Fundamental Change, but
in any event at least thirty-five Business Days prior to such anticipated Effective Date, the Company shall mail to each Noteholder, the Trustee and the Conversion Agent written notice of, and shall issue a press release indicating, and publicly
announce, through a public medium that is customary for such announcements, and publish on the Company’s website, the anticipated effective date of such proposed Make-Whole Fundamental Change. Each such press release notice, announcement and
publication shall also state that in connection with such Make-Whole Fundamental Change, the Company shall increase, in accordance herewith, the Conversion Rate applicable to Notes entitled as provided herein to such increase (along with a
description of how such increase shall be calculated and the time periods during which Notes must be surrendered in order to be entitled to such increase). No later than the actual Effective Date of each Make-Whole Fundamental Change, the Company
shall mail to each Noteholder, the Trustee and the Conversion Agent written notice of, and shall issue a press release indicating, and publicly announce, through a public medium that is customary for such announcements, and publish on the
Company’s website, such Effective Date and the amount by which the Conversion Rate has been so increased. 
 Nothing in
this Section 15.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 15.04 in respect of a Make-Whole Fundamental Change. 
 Section 15.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows: 
 (a) If the Company issues shares of Common Stock as a dividend or distribution to all holders of the outstanding Common Stock on shares of
Common Stock, or if the Company effects a share split or share combination, the Conversion Rate will be adjusted based on the following formula: 
  

								
	 CR'
	 	=	 	CR0	×	 	OS'    
	 	 	 	OS0    

 where 
  

					
	 CR0
	 	=	 	the Conversion Rate in effect immediately prior to the open of business on
the Ex-Dividend Date for such dividend or distribution,
or the open of
business on the effective date of such share split or share combination, as
the case may be;
			
	 CR'
	 	=	 	the Conversion Rate in effect immediately after the open of business on
the Ex-Dividend Date for such dividend or distribution, or the open of
business on the effective date of
such share split or share combination, as
the case may be;

  

 58 

					
	OS0	 	=	 	the number of shares of Common Stock outstanding immediately prior to the open of business on the Ex-Dividend Date for such dividend or
distribution, or the open of business on the effective date of such share split or share combination, as the case may be; and
			
	OS'	 	=	 	the number of shares of Common Stock outstanding immediately after such dividend or distribution, or the effective date of such share split or share combination, as the case may
be.

 Such adjustment shall become effective immediately after the opening of business on the
Ex-Dividend Date for such dividend or distribution, or the effective date for such share split or share combination. If any dividend or distribution of the type described in this Section 15.04(a) is declared but not so paid or made, or the
outstanding shares of Common Stock are not split or combined, as the case may be, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, or split or
combine the outstanding shares of Common Stock, as the case may be, to the Conversion Rate that would then be in effect if such dividend, distribution, share split or share combination had not been declared or announced. 
 (b) In case the Company shall distribute to all or substantially all holders of its Common Stock any rights, options or warrants entitling
them for a period of not more than sixty days after the declaration date of such distribution to subscribe for or purchase shares of the Common Stock, at a price per share less than the Last Reported Sale Price of the Common Stock on the Trading Day
immediately preceding the declaration date for such distribution, the Conversion Rate shall be adjusted based on the following formula: 
  

								
	 CR'
	 	=	 	CR0	×	 	OS0+X    
	 	 	 	OS0+Y    

 where 
  

					
	 CR0
	 	=	 	the Conversion Rate in effect immediately prior to the open of business on
the Ex-Dividend Date for such
distribution;
			
	 CR'
	 	=	 	the Conversion Rate in effect immediately after the open of business on
the Ex-Dividend Date for such distribution;
			
	 OS0
	 	=	 	the number of shares of the Common Stock that are outstanding
immediately prior to the open of business on the Ex-Dividend Date for
such distribution;
			
	 X
	 	=	 	the total number of shares of the Common Stock issuable pursuant to such
rights, options or warrants; and

  

 59 

					
			
	Y	 	=	 	the number of shares of the Common Stock equal to the aggregate price
payable to exercise such rights, options or
warrants, divided by the
average of the Last Reported Sale Prices of Common Stock over the
ten consecutive Trading Day period ending on the Trading Day
immediately preceding the Ex-Dividend Date relating to such
distribution of such
rights, options or warrants.

 Such adjustment shall be successively made whenever any such rights, options or warrants are
distributed and shall become effective immediately after the opening of business on the Ex-Dividend Date for such distribution. The Company shall not issue any such rights, options or warrants in respect of shares of the Common Stock held in
treasury by the Company. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options 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, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate
shall again be adjusted to be the Conversion Rate that would then be in effect if such Ex-Dividend Date for such distribution had not been fixed. 
 In determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than such Last Reported Sale Price of the Common Stock, and in determining the
aggregate offering price of such shares of the Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such
consideration, if other than cash, to be determined by the Board of Directors. In no event shall the Conversion Rate be decreased pursuant to this Section 15.04(b). 
 (c) In case the Company shall distribute shares of its Capital Stock, evidences of its indebtedness or other of its assets or property
other than (i) dividends or distributions covered by Section 15.04(a) and Section 15.04(b), (ii) dividends or distributions paid exclusively in cash, and (iii) Spin-Offs to which the provisions set forth below in this
Section 15.04(c) shall apply (any of such shares of Capital Stock, indebtedness, or other asset or property hereinafter in this Section 15.04(c) called the “Distributed Property”), to all or substantially all holders of
its Common Stock, then, in each such case the Conversion Rate shall be adjusted based on the following formula: 
  

								
	 CR'
	 	=	 	CR0	×	 	SP0    
	 	 	 	SP0-FMV    

 where 
  

					
	 CR0
	 	=	 	the Conversion Rate in effect immediately prior to the open of business on
the Ex-Dividend Date for such
distribution;
			
	 CR'
	 	=	 	the Conversion Rate in effect immediately after the open of business on
the Ex-Dividend Date for such distribution;

  

 60 

					
	SP0	 	=	 	the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Trading Day
immediately preceding the Ex-Dividend Date for such distribution; and
			
	FMV	 	=	 	 the fair market value (as determined by the Board of Directors) of the
 shares of Capital Stock, evidences of indebtedness, assets or property
 distributed with respect to each outstanding share of
the Common Stock as of the open of business on the Ex-Dividend Date for such distribution.

 Such adjustment shall become effective
immediately prior to the opening of business on the Ex-Dividend Date for such distribution; provided that if “FMV” as set forth above is equal to or greater than “SP0” as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall receive on the date on which the Distributed Property is
distributed to holders of Common Stock, for each $1,000 principal amount of Notes the amount of Distributed Property such holder would have received had such holder owned a number of shares of Common Stock equal to the Conversion Rate on the Record
Date for such distribution. If such 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 “FMV” for purposes of this Section 15.04(c) 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 Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution. 
 With respect to an adjustment pursuant to this Section 15.04(c) where there has been a dividend or other distribution on the Common
Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company (a “Spin-Off”), the Conversion Rate in effect immediately before the close of
business on the tenth Trading Day immediately following, and including, the effective date of the Spin-Off will be increased based on the following formula: 
  

								
	 CR'
	 	=	 	CR0	×	 	FMV0+MP0    
	 	 	 	MP0    

 where 
  

					
	CR0	 	=	 	the Conversion Rate in effect immediately prior to the close of business on the tenth Trading Day immediately following, and including, the effective date of the Spin-Off;
			
	CR'	 	=	 	the Conversion Rate in effect immediately after the close of business on the tenth Trading Day immediately following, and including, the effective date of the Spin-Off;
			
	FMV0	 	=	 	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock over the
first ten consecutive Trading Day period immediately following, and including, the effective date of the Spin-Off; and

  

 61 

					
	MP0	 	=	 	the average of the Last Reported Sale Prices of the Common Stock over the first ten consecutive Trading Day period immediately following and including the effective date of the
Spin-Off.

 The adjustment to the Conversion Rate under the preceding paragraph shall become effective at the
close of business on the tenth Trading Day immediately following, and including, the effective date of the Spin-Off; provided that, for purposes of determining the Conversion Rate, in respect of any conversion during the ten Trading Days
immediately following, and including, the effective date of any Spin-Off, references in the portion of this Section 15.04(c) related to Spin-Offs to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have
elapsed between the effective date of such Spin-Off and the Conversion Date for such conversion. 
 Subject in all respect to
Section 15.10, rights, options or warrants distributed by the Company to all holders of its Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either
initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common Stock;
(ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 15.04 (and no adjustment to the Conversion Rate under
this Section 15.04 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 15.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights,
options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with
respect to new rights, options or warrants with such rights (and a termination or expiration of the existing rights, options or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed
distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the 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 15.04 was made, (1) in the case of any such rights, options 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 Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of
such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued. 
  

 62 

 For purposes of this Section 15.04(c), Section 15.04(a), and
Section 15.04(b), any dividend or distribution to which this Section 15.04(c) is applicable that also includes shares of Common Stock, or rights, options or warrants to subscribe for or purchase shares of Common Stock to which
Section 15.04(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 Common Stock or rights, options or warrants to
which Section 15.04(c) applies (and any Conversion Rate adjustment required by this Section 15.04(c) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such
shares of Common Stock or such rights, options or warrants (and any further Conversion Rate adjustment required by Section 15.04(a) and Section 15.04(b) with respect to such dividend or distribution shall then be made), except (A) the
Ex-Dividend Date of such dividend or distribution shall be substituted as “the Ex-Dividend Date,” “the Ex-Dividend Date relating to such distribution of such rights, options or warrants” and “the Ex-Dividend Date for such
distribution” within the meaning of Section 15.04(a) and Section 15.04(b) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding immediately prior to the Ex-Dividend
Date for such dividend or distribution, or the effective date of such share split or share combination, as the case may be” within the meaning of Section 15.04(a) or “outstanding immediately prior to the Ex-Dividend Date for such
dividend or distribution” within the meaning of Section 15.04(b). 
 In no event shall the Conversion Rate be
decreased pursuant to this Section 15.04(c). 
 (d) If any cash dividend or distribution is made to all or substantially
all holders of its Common Stock, the Conversion Rate shall be adjusted based on the following formula: 
  

								
	 CR'
	 	=	 	CR0	×	 	SP0    
	 	 	 	SP0-C    

 where 
  

					
	CR0	 	=	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	CR'	 	=	 	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	 	=	 	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
			
	C	 	=	 	the amount in cash per share the Company distributes to holders of its Common Stock.

 Such adjustment shall become effective immediately after the opening of business on the Ex-Dividend
Date for such dividend or distribution; provided that if “C” as set forth above is equal 

  

 63 

 
to or greater than “SP0” as set forth above,
in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive on the date on which the relevant cash dividend or distribution is distributed to holders of Common Stock, for each $1,000
principal amount of Notes, the amount of cash such holder would have received had such holder owned a number of shares equal to the Conversion Rate on the Record Date for such distribution. 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. 
 For the avoidance of doubt, for purposes of this Section 15.04(d), in the event of any reclassification of the Common Stock, as a result of which the Notes become convertible into more than one class of Common
Stock, if an adjustment to the Conversion Rate is required pursuant to this Section 15.04(d), references in this Section to one share of Common Stock or Last Reported Sale Price of one share of 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 Notes are then convertible equal to the numbers of shares of such class issued in respect of one share of Common Stock in such reclassification.
The above provisions of this paragraph shall similarly apply to successive reclassifications. 
 In no event shall the
Conversion Rate be decreased pursuant to this Section 15.04(d). 
 (e) If the Company or any of its Subsidiaries makes a
payment in respect of a tender offer or exchange offer for the Common Stock and the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the average of the Last Reported Sale Prices of the Common
Stock over the ten consecutive Trading-Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased
based on the following formula: 
  

								
	 CR'
	 	=	 	CR0  	×	 	 AC+(SP'×OS')

	 	 	 	OS0×SP'

 where 
  

					
	 CR0
	 	=	 	the Conversion Rate in effect at the close of business on the last Trading Day of the period of ten consecutive Trading Days commencing on, and including, the Trading Day next succeeding the
date such tender or exchange offer expires;
			
	 CR'
	 	=	 	the Conversion Rate in effect at the open of business on first day following the last Trading Day of the period of ten consecutive Trading Days commencing on, and including, the Trading Day
next succeeding the date such tender or exchange offer expires;
			
	 AC
	 	=	 	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;

  

 64 

					
	OS0	 	=	 	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to such tender offer or exchange
offer);
			
	OS’	 	=	 	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to such tender offer or exchange offer);
and
			
	SP’	 	=	 	the average of the Last Reported Sale Prices of Common Stock over the ten consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or
exchange offer expires.

 Such adjustment shall become effective at the close of business on the tenth Trading Day next
succeeding the date such tender or exchange offer expires; provided that, for purposes of determining the Conversion Rate, in respect of any conversion during the ten Trading Days following the date that any such tender or exchange offer
expires, references in this Section 15.04(e) to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date that such tender or exchange offer expires and the Conversion Date for such
conversion. 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 or all or any portion of 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 or had been made only in respect of the purchases that had been effected. In no event
shall the Conversion Rate be decreased pursuant to this Section 15.04(e). 
 (f) The term “Record Date”
shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock (or other security) have the right to receive any cash, securities or other property or in which the Common Stock (or other
applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed
by the Board of Directors or by statute, contract or otherwise). 
 (g) Except as stated herein, the Company shall not adjust
the Conversion Rate for the issuance of shares of its Common Stock or any securities convertible into or exchangeable for shares of its Common Stock or the right to purchase shares of its Common Stock or such convertible or exchangeable securities.

 (h) Notwithstanding this Section 15.03 or any other provision of this Indenture or the Notes, if any Conversion Rate
adjustment becomes effective, or any Ex-Dividend Date for any issuance, dividend or distribution (relating to a required Conversion Rate adjustment) occurs, during the period beginning on, and including, the open of business on a Conversion Date and
ending on, and including, (x) the close of business on the third Trading Day immediately 

  

 65 

 
following the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation solely in shares of Common Stock) or (y) the
close of business on the last Trading Day of a related Cash Settlement Averaging Period (in the case of any other Settlement Method), the Board of Directors shall make adjustments to the Conversion Rate and the amount of cash or number of shares of
Common Stock issuable upon conversion of the Notes, as the case may be, as is be necessary or appropriate to effect the intent of this Section 15.03 and the other provisions of Article 15 and to avoid unjust or inequitable results, as
determined in good faith by the Board of Directors. Any adjustment made pursuant to this Section 15.03(h) shall apply in lieu of the adjustment or other term that would otherwise be applicable. 
 (i) In addition to those required by clauses (a), (b), (c), (d) and (e) of this Section 15.04, and to the extent permitted
by applicable law and subject to the applicable rules of the Nasdaq Global Select Market, the Company from time to time may increase the Conversion Rate by any amount for a period of at least twenty Business Days if the Board of Directors determines
that such increase would be in the Company’s best interest. In addition, the Company may also (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common
Stock in connection with any dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the holder of each Note at its
last address appearing on the Note Register provided for in Section 2.06 a notice of the increase at least fifteen days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and
the period during which it will be in effect. 
 (j) The applicable Conversion Rate will not be adjusted: 
 (i) upon the issuance of any shares of the Common Stock pursuant to any present or future plan providing for the reinvestment of dividends
or interest payable on the Company’s securities and the investment of additional optional amounts in shares of the Common Stock under any plan; 
 (ii) upon the issuance of any shares of the Common Stock pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of the Company’s
Subsidiaries; 
 (iii) upon the issuance of any shares of the Common Stock pursuant to any option, warrant, right or
exercisable, exchangeable or convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued; 
 (iv) for a change in the par value of the Common Stock; 
 (v) for accrued and unpaid interest, including Additional Interest, if any; or 
 (vi) for any transactions described in this Section 15.04 if Noteholders participate (as a result of holding the Notes, and at the
same time as holders of Common Stock participate) in such transactions as if such Noteholders held a number shares of Common Stock equal to the Conversion Rate at the time such adjustment would be required, multiplied by the principal amount
(expressed in thousands) of Notes held by such Noteholder, without having to convert their Notes. 
  

 66 

 (k) All calculations and other determinations under this Article 15 shall be made by the
Company and shall be made to the nearest one-ten thousandth (1/10,000) of a share. 
 (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 Note at its last address appearing on the Note Register provided for in
Section 2.06 of this Indenture, within ten days of the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 
 (m) For purposes of this Section 15.04, the number of shares of Common Stock at any time outstanding shall not include shares held in
the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in
the treasury of the Company. 
 Section 15.05. 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 Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion. 
 Section 15.06. Effect of Reclassification, Consolidation, Merger or Sale. Upon the occurrence of (i) any reclassification or change of
the outstanding shares of 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 covered by Section 15.04(a)), (ii) any
consolidation, merger or combination involving the Company, or (iii) any sale or conveyance of all or substantially all of the property and assets of the Company to any other Person, in each case as a result of which holders of Common Stock
shall be entitled to receive cash, securities or other property or assets with respect to or in exchange for such Common Stock (any such event a “Merger Event”), then: 
 (a) the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which
shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) permitted under Section 11.01(f) providing for the conversion and
settlement of the Notes as set forth in this Indenture. Such supplemental indenture shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 15. If, in the case of any
Merger Event, the 

  

 67 

 
Reference 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 Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent required by the Board of Directors and practicable the provisions providing for the repurchase rights set
forth in Article 16 herein. 
 In the event the Company shall execute a supplemental indenture pursuant to this
Section 15.06, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefore, the kind or amount of cash, securities or property or asset that will comprise the Reference Property after any
such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Noteholders. The Company shall cause notice of the execution of such
supplemental indenture to be mailed to each Noteholder, at its address appearing on the Note Register provided for in this Indenture, within twenty days after execution thereof. Failure to deliver such notice shall not affect the legality or
validity of such supplemental indenture. 
 (b) Notwithstanding the provisions of Section 15.02(b), and subject to the
provisions of Section 15.01 and Section 15.03, at and after the effective time of such Merger Event, (i) the right to convert each $1,000 principal amount of Notes into cash, shares of Common Stock or a combination of cash and shares
of Common Stock at the Company’s election as set forth in Section 15.02 will be changed to a right to convert such Note into cash, the kind and amount of shares of stock, securities or other property or assets (including cash or any
combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such transaction would have owned or been entitled to receive (the “Reference Property”) or a combination of
cash and Reference Property at the Company’s election and (ii) the related Conversion Obligation shall be settled as set forth under clause (c) below, it being understood and agreed that for purposes of Section 15.01(b),
references therein to “the Last Reported Sale Price of the Common Stock” shall be deemed at and after the effective time of such Merger Event to be references to “the Last Reported Sale Price of a unit of Reference Property comprised
of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been entitled to
receive based on the Weighted Average Consideration.” The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 15.06. None of the foregoing provisions shall affect the right of a holder of
Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set forth in Section 15.01 and Section 15.02 prior to the effective date of such Merger Event. 

(c) With respect to each $1,000 principal amount of Notes surrendered for conversion after the effective date of any such Merger Event,
the Company’s Conversion Obligation shall be settled in cash or units of Reference Property, at the Company’s election, in accordance with Section 15.02(b) as follows: 
  

 68 

 (i) (A) if the Company elects to satisfy its Conversion Obligation in respect of such
conversion by delivering solely Reference Property, the Company shall deliver to the converting Noteholder a number of units of Reference Property (each such unit comprised of the kind and amount of shares of stock, securities or other property or
assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been entitled to receive based on the Weighted Average Consideration) equal to (1) the
aggregate principal amount of Notes to be converted, divided by $1,000, multiplied by (2) the then-applicable Conversion Rate; (B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by
paying solely cash, the Company shall pay to the converting Noteholder cash in an amount, per $1,000 principal amount of Notes equal to the sum of the Daily Conversion Values for each of the thirty consecutive Trading Days during the related Cash
Settlement Averaging Period, such Daily Conversion Values determined as if the reference to “the Daily VWAP of the Common Stock” in definition thereof were instead a reference to “the Daily VWAP of a unit of Reference Property
comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been
entitled to receive based on the Weighted Average Consideration”; and (C) if the Company elects to satisfy its Conversion Obligation through delivery of a combination of cash and Reference Property, the Company shall deliver in respect of
each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the thirty consecutive Trading Days during the Cash Settlement Averaging Period for such Note, such Daily
Settlement Values determined as if the reference to “the Daily VWAP of the Common Stock” in definition of Daily Conversion Value and Daily Share Amount were instead a reference to “the Daily VWAP of a unit of Reference Property
comprised of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of one share of Common Stock immediately prior to such Merger Event would have owned or been
entitled to receive based on the Weighted Average Consideration.” 
 (ii) The Company will deliver the cash in lieu of
fractional units of Reference Property as set forth pursuant to Section 15.02(l) (provided that the amount of such cash shall be determined as if references in such Section to “the Last Reported Sale Price of the Common Stock”
were instead a reference to “the Last Reported Sale Price of a unit of Reference Property composed of the kind and amount of shares of stock, securities or other property or assets (including cash or any combination thereof) that a holder of
one share of Common Stock immediately prior to such Merger Event would have owned or been entitled to receive based on the Weighted Average Consideration”). 
 (iii) The Daily Settlement Amounts (if applicable) and Daily Conversion Values (if applicable) shall be determined by the Company promptly
following the last day of the Cash Settlement Averaging Period. 
 (iv) For purposes of this Section 15.06, the
“Weighted Average Consideration” shall mean the weighted average of the types and amounts of consideration received by the holders of the Common Stock entitled to receive cash, securities or other property or assets with respect to
or in exchange for such Common Stock in any Merger Event who affirmatively make such an election. 
  

 69 

 (v) The Company shall notify the holders of the Weighted Average Consideration as soon as
practicable after the Weighted Average Consideration is determined. 
 (d) The above provisions of this Section shall
similarly apply to successive Merger Events. 
 Section 15.07. Certain Covenants. (a) The Company covenants that all shares
of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 
 (b) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require
registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the Commission,
secure such registration or approval, as the case may be. 
 (c) The Company further covenants that if at any time the Common
Stock shall be listed on any national securities exchange or automated quotation system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common Stock issuable
upon conversion of the Notes. 
 Section 15.08. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not
at any time be under any duty or responsibility to any Noteholder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with
respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion
Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the
Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock
certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the
generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 15.06 relating
either to the kind or amount of shares of stock or securities or property (including cash) receivable by Noteholders upon the conversion of their Notes after any event referred to in such Section 15.06 or to any adjustment to be made with
respect thereto, but, subject to the provisions of Section 8.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’
Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any
event contemplated by Section 15.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in
Section 15.01(b) with respect to the commencement or termination of such conversion rights, on which notices 

  

 70 

 
the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent
immediately after the occurrence of any such event or at such other times as shall be provided for in Section 15.01(b). 
 Section 15.09. Notice to Holders Prior to Certain Actions. In case: (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Conversion Rate pursuant
to Section 15.04; or 
 (b) the Company shall authorize the granting to all of the holders of its Common Stock of rights,
options or warrants to subscribe for or purchase any share of any class or any other rights, options or warrants; or 
 (c) of
any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any
consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or 
 (d) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company; 
 the Company shall cause to be filed with the Trustee and to be mailed to each Noteholder at its address appearing on the Note Register, provided for in
Section 2.06 of this Indenture, as promptly as possible but in any event at least twenty days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such
dividend, distribution or rights, options or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or (ii) the date
on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled
to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not
affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. 
 Section 15.10. Stockholder Rights Plans. To the extent that the Company has a stockholder rights plan or other “poison pill” in effect upon conversion of the Notes, each share of Common Stock, if
any, issued upon such conversion 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 such stockholder rights plan or poison pill, 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 stockholder rights agreement so that the holders of the Notes would not be entitled to receive any rights in respect of Common Stock, if any, issuable upon conversion of the Notes, the Conversion Rate will be adjusted at the time of
separation as if the Company has distributed to all holders of Common Stock, shares of Capital Stock of the Company, evidence of indebtedness or assets as provided in Section 15.04(c), subject to readjustment in the event of the expiration,
termination or redemption of such rights. 
  

 71 

 Section 15.11. Exchange in Lieu of Conversion. When a holder surrenders its Notes for
conversion, the Company may, at its election, direct the Conversion Agent to surrender, on or prior to the second Business Day following the relevant Conversion Date, such Notes to a financial institution designated by the Company (the
“Designated Institution”) for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion for exchange in lieu of conversion, the Designated Institution must agree to timely deliver, in exchange for such
Notes, the shares of Common stock and/or cash that would otherwise be due upon conversion as described in Section 15.02 above and in respect of which the Company has notified to converting Noteholders. If the Company makes the election
described above, the Company shall, by the close of business on the second Business Day following the relevant Conversion Date as part of its Settlement Notice, notify the holder surrendering its Notes for conversion that it has made such election.
In addition, the Company shall concurrently notify the Designated Institution of the Settlement Method (and, if applicable, the Specified Dollar Amount) that Company has elected with respect to such conversion and the relevant deadline for delivery
of the consideration due upon conversion. Any Notes exchanged by the Designated Institution will remain outstanding. 
 (a) If
the Designated Institution agrees to accept any Notes for exchange but does not timely deliver the related consideration due upon conversion to the Conversion Agent, or if the Designated Institution does not accept such Notes for exchange, the
Company shall, within the time period specified in Section 15.02(e), convert such Notes into cash and/or shares of Common Stock, as applicable in accordance with the provisions of Section 15.02. 
 (b) For the avoidance of doubt, in no event will the Company’s designation of a Designated Institution pursuant to this
Section 15.11 require the Designated Institution to accept any Notes for exchange. 
 Section 15.12. Limit on Issuance of
Shares of Common Stock upon Conversion. Notwithstanding anything contained elsewhere in this Indenture, if and to the extent required by the shareholder approval rules or listing standards of any national or regional securities exchange that are
applicable to the Company at the time any Notes are converted hereunder, in no event will the aggregate number of shares of Common Stock issuable upon conversion of the Notes exceed 19.99% of the Common Stock outstanding as of February 20, 2008
(which is equivalent to issuing upon conversion approximately 65.4050 shares of Common Stock per $1,000 principal amount of Notes (if the Initial Purchasers do not exercise their option to purchase additional Notes in full as set forth in the
Purchase Agreement) or approximately 58.5203 shares per $1,000 principal amount of Notes (if the Initial Purchasers exercise their option to purchase additional Notes in full as set forth in the Purchase Agreement) (as applicable, the
“Conversion Rate Cap,” and subject to pro rata adjustment for any partial exercise by the Initial Purchasers of their option to purchase additional Notes as set forth in the Purchase Agreement) and if an event occurs that
would otherwise result in an increase in the Conversion Rate above the Conversion Rate Cap, if and to the extent required by the shareholder approval rules or listing standards of any national or regional securities exchange that are applicable to
the Company at the time any Notes are converted hereunder, the Company will either obtain stockholder approval of any issuance of Common Stock upon conversion of the Notes in excess such limitations or deliver cash in lieu of any shares of Common
Stock otherwise deliverable upon conversions in excess of such limitations (based on the Last Reported Sale Price of the Company’s Common Stock on the Trading Day immediately prior to the relevant Conversion Date).

 ARTICLE 16 
 REPURCHASE OF NOTES AT OPTION OF HOLDERS 
 Section 16.01. [Reserved.] 
 Section 16.02. Repurchase at Option of Holders upon a Fundamental Change. (a) If there shall occur a Fundamental Change at any time
prior to the Maturity Date, then each Noteholder shall have the right, at such holder’s option, to require the Company to repurchase for cash all of such holder’s Notes, or any portion thereof that is an integral multiple of $1,000
principal amount, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than twenty Business Days and not more than thirty five Business Days after the date of the Fundamental Change
Company Notice (as defined below) at a repurchase price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, including unpaid Additional Interest, if any, thereon to, but excluding, the Fundamental Change
Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date is after an Interest Record Date and on or prior to the related Interest Payment Date, in which case interest accrued to the
Interest Payment Date will be paid to holders of the Notes as of the preceding Interest Record Date and the Fundamental Change Repurchase Price payable to the holder surrendering the Note for repurchase pursuant to this Article 16 shall be equal to
the principal amount of Notes subject to repurchase. Repurchases of Notes under this Section 16.02 shall be made, at the option of the holder thereof, upon: 
 (i) delivery to the Paying Agent by a holder of a duly completed notice (the “Fundamental Change Repurchase Notice”) in
the form set forth on the reverse of the Note as Exhibit C thereto on or prior to the Business Day immediately preceding the Fundamental Change Repurchase Date; and 
 (ii) delivery or book-entry transfer of the Notes to the Paying Agent at any time after delivery of the Fundamental Change Repurchase
Notice (together with all necessary endorsements) at the Corporate Trust Office of the Paying Agent in The Borough of Manhattan, such delivery being a condition to receipt by the holder of the Fundamental Change Repurchase Price therefor;
provided that such Fundamental Change Repurchase Price shall be so paid pursuant to this Section 16.02 only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Fundamental
Change Repurchase Notice. 
 The Fundamental Change Repurchase Notice shall state: 
 (A) if certificated, the certificate numbers of Notes to be delivered for repurchase; 
 (B) the portion of the principal amount of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and 

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

  

 73 

 provided, however, that if the Notes are not in certificated form, the Fundamental Change
Repurchase Notice must comply with appropriate Depositary procedures. 
 Any repurchase by the Company contemplated pursuant
to the provisions of this Section 16.02 shall be consummated by the payment of the Fundamental Change Repurchase Price on the later of the Fundamental Change Repurchase Date and the time of the book-entry transfer or delivery of the Note as
described in Section 16.04(a). 
 Notwithstanding anything herein to the contrary, any holder delivering to the Paying
Agent the Fundamental Change Repurchase Notice contemplated by this Section 16.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day
immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 16.03 below. 
 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of
withdrawal thereof. 
 (b) On or before the twentieth day after the occurrence of the effective date of a Fundamental Change,
the Company shall mail or cause to be mailed to all holders of record of the Notes a notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of the Fundamental Change and of the repurchase right at
the option of the holders arising as a result thereof. Such mailing shall be by first class mail. The Company shall also deliver a copy of the Fundamental Change Company Notice to the Trustee, the Paying Agent and the Conversion Agent within five
Business Days after the effective date of the Fundamental Change. Simultaneously with the providing of such notice, the Company will also publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper
of general circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the Company may use at that time. Each Fundamental Change Company Notice shall specify: 
 (i) the events causing the Fundamental Change; 
 (ii) the effective date of the Fundamental Change; 
 (iii) the last date on which a holder may exercise the repurchase right pursuant to this Article 16; 
 (iv) the Fundamental Change Repurchase Price; 
 (v) the Fundamental Change Repurchase Date; 
 (vi) the name and address of the Paying Agent and the Conversion Agent, if applicable; 
 (vii) if applicable, the applicable Conversion Rate, any adjustments to the applicable Conversion Rate; 
  

 74 

 (viii) if applicable, that the Notes with respect to which a Fundamental Change
Repurchase Notice has been delivered by a holder may be converted only if the holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of the Indenture; 
 (ix) that the holder must exercise the repurchase right on or prior to the close of business on the Business Day immediately preceding the
Fundamental Change Repurchase Date (the “Fundamental Change Expiration Time”); 
 (x) that the holder shall
have the right to withdraw any Notes surrendered prior to the Fundamental Change Expiration Time; and 
 (xi) the procedures
that holders must follow to require the Company to repurchase their Notes. 
 No failure of the Company to give the foregoing
notices and no defect therein shall limit the Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 16.02. 
 (c) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of the holders upon a Fundamental Change if
the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Repurchase Date (except in the case of an acceleration resulting from a default by the Company in the payment
of the Fundamental Change Repurchase Price with respect to such Notes). 
 (d) In connection with any purchase offer, the
Company will: 
 (i) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange
Act, if required under the Exchange Act, 
 (ii) file a Schedule TO or any successor or similar schedule, if required under
the Exchange Act, and 
 (iii) otherwise comply with all federal and state securities laws in connection with any offer by the
Company to purchase the Notes. 
 Section 16.03. Withdrawal of Fundamental Change Repurchase Notice. (a) A Fundamental
Change Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 16.03 at any time prior to the close of business on the Business
Day immediately preceding the Fundamental Change Repurchase Date, specifying: 
 (i) the certificate number, if any, of the
Note in respect of which such notice of withdrawal is being submitted, or the appropriate Depositary information if the Note in respect of which such notice of withdrawal is being submitted is represented by a Global Note, 
  

 75 

 (ii) the principal amount of the Note with respect to which such notice of withdrawal is
being submitted, and 
 (iii) the principal amount, if any, of such Note that remains subject to the original Fundamental
Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 
 provided,
however, that if the Notes are not in certificated form, the notice must comply with appropriate procedures of the Depositary. 
 Section 16.04. Deposit of Fundamental Change Repurchase Price. (a) 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) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate
Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to the Fundamental Change Expiration
Time) will be made on the later of (i) the Fundamental Change Repurchase Date with respect to such Note (provided the holder has satisfied the conditions in Section 16.02) and (ii) the time of book-entry transfer or the
delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the holder thereof in the manner required by Section 16.02 by mailing checks for the amount payable to the holders of such Notes entitled thereto as they
shall appear in the Note Register, provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such
payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price. 
 (b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions
thereof that are to be repurchased as a result of the corresponding Fundamental Change, then (i) such Notes will cease to be outstanding, (ii) interest, including Additional Interest, if any, will cease to accrue on such Notes, and
(iii) all other rights of the holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price, and previously accrued but unpaid interest, including Additional Interest, if any, upon delivery of the
Notes), whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent. 
 (c) Upon surrender of a Note that is to be repurchased in part pursuant to 16.02, the Company shall execute and the Trustee shall authenticate and deliver to the holder a new Note in an authorized denomination equal
in principal amount to the unrepurchased portion of the Note surrendered.

 78 

 
authorized by this Indenture and those Sections to authenticate and deliver Notes. For all purposes of this Indenture, the authentication and delivery of
Notes by the authenticating agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a certificate of authentication executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy
any requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such authenticating agent shall at all times be a Person eligible to serve as trustee hereunder pursuant to Section 8.09.

or the authenticating agent or such successor corporation or other entity. 
 Any authenticating agent may at any time resign
by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon

 as Authenticating Agent, certifies that this is one of the Notes described 
 in the within-named Indenture. 
 By:

APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY. 
 Section 17.15. Force Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its
obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural
catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts that are consistent with accepted
practices in the banking industry to resume performance as soon as practicable under the circumstances.
