“Debentures”). All terms used in this Supplemental Indenture that are defined in the Indenture, either directly or by reference therein, have the respective meanings assigned to them therein, except to the extent such terms
are otherwise defined in this Supplemental Indenture or the context clearly requires otherwise. 
 RECITALS 
 WHEREAS, Section 9.02 of the Indenture provides that the Company and the Trustee may amend or supplement the Indenture with the consent of the
Holders of at least a majority in principal amount of the Debentures; 
 WHEREAS, the Company has offered to convert (the
“Offer”) each $1000 principal amount of the Debentures to (a) 242.6595 shares of Class A common stock, no par value per share, of the Company, (b) a premium of $193.85 payable in cash and (c) accrued and
unpaid interest from February 15, 2006 up to, but not including, the payment date for the Conversion Offer, on the terms and subject to the conditions set forth in then Company’s Prospectus and Solicitation Statement dated April 12,
2006, as amended and supplemented, and the related Letter of Transmittal and Consent, delivered to Holders; 
 WHEREAS, in connection with
the Offer, the Company has solicited consents (the “Consent Solicitation”) from the Holders to a proposed amendment to the Indenture to eliminate the Event of Default set forth in Section 6.01(7) of the Indenture (the
“Proposed Amendment”); 
 WHEREAS, pursuant to the Consent Solicitation, the Holders of at least majority in
principal amount of the Debentures have consented to the Proposed Amendment; 
 WHEREAS, the Company desires to execute and deliver, and has
requested the Trustee to join with the Company and the Guarantor in the execution and delivery of, this Supplemental Indenture for the purpose of amending the Indenture to effect the Proposed Amendment; 
 WHEREAS, the Company has been authorized by a resolution of its Board of Directors to execute and deliver this Supplemental Indenture; 
 WHEREAS, this Supplemental Indenture has been duly authorized by all necessary corporate action on the part of the Guarantor; and 
 WHEREAS, the Company has furnished, or caused to be furnished, to the Trustee, and the Trustee has received, (i) an Officers’ Certificate
complying with Sections 9.06 and 13.04 of the Indenture; and (ii) an Opinion of Counsel stating, among other things, that this Supplemental Indenture is authorized or permitted by the Indenture, as well as a certified copy of the 

  

 1 

 
resolutions of the Company’s Board of Directors authorizing the execution of this Supplemental Indenture. 
 NOW, THEREFORE, in consideration of the foregoing premises and for other good and valuable consideration, the receipt of which is hereby acknowledged,
the Company, the Guarantor and the Trustee mutually covenant and agree for the equal and proportionate benefit of the Holders as follows: 
 1. Proposed Amendment. Section 6.01(7) of the Indenture hereby is deleted in its entirety and replaced with the phrase “Intentionally Omitted.” Any references to such deleted section in the Indenture hereby also are
deleted in their entirety, except as otherwise provided in Section 2 below. 
 2. Defined Terms. The definition of the defined
term “Payment Default” used in the Indenture, which definition is set forth in the section that is eliminated by this Supplemental Indenture and which defined term is still used in the Indenture after giving effect to the amendment to the
Indenture set forth in this Supplemental Indenture, hereby is deemed a part of, and is deemed to be defined in, Section 1.01 (Definitions) of the Indenture, and hereby is deemed to be in alphanumeric order within Section 1.01 (Definitions)
of the Indenture. 
 3. Effect of Supplemental Indenture. Except as modified or amended by this Supplemental Indenture, all provisions
of the Indenture shall remain in full force and effect. In the event of conflict between the terms and conditions contained in the Debentures and those contained in the Indenture, as modified and amended by this Supplemental Indenture, the
provisions of the Indenture, as modified and amended by this Supplemental Indenture, shall control. 
 4. Interpretation. Upon the
execution and delivery of this Supplemental Indenture, the Indenture shall be modified and amended in accordance with this Supplemental Indenture, and all the terms and conditions of the Indenture and this Supplemental Indenture shall be read
together as though they constitute one instrument, except that, in case of conflict, the provisions of this Supplemental Indenture shall control. The Indenture, as modified and amended by this Supplemental Indenture, is hereby ratified and confirmed
in all respects and shall bind every Holder of the Debentures. 
 5. Trustee. 
 (a) Trustee’s Acceptance. Subject to Section 3 above, the Trustee hereby accepts this Supplemental Indenture and agrees to perform the
same under the terms and conditions set forth in the Indenture. 
 (b) Trustee Not Responsible for Recitals. The Trustee shall not be
responsible in any manner whatsoever for, or in respect of, the validity or sufficiency of this Supplemental Indenture, or for, or in respect of, the recitals contained herein, all of which recitals are made solely by the Company. 
 (c) Certain Duties and Responsibilities of the Trustee. In entering into this Supplemental Indenture, the Trustee shall be entitled to the benefit
of every provision of the 

  

 2 

 
Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee, whether or not elsewhere herein so provided.

 6. Severability. In the event any provision of this Supplemental Indenture shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions of this Supplemental Indenture shall not in any way be affected or impaired thereby. 
 7. Conflict with Trust Indenture Act. If any provision of this Supplemental Indenture limits, qualifies or conflicts with any provision of the Trust Indenture Act of 1939, as amended (the
“TIA”), that is required under the TIA to be a part of or govern any provision of this Supplemental Indenture, such provision of the TIA shall control. If any provision of this Supplemental Indenture modifies or excludes any
provision of the TIA that may be so modified or excluded, such provision of the TIA shall be deemed to apply to the Indenture as so modified or excluded by this Supplemental Indenture, as the case may be. 
 8. Benefits of this Supplemental Indenture. Nothing in this Supplemental Indenture or the Debentures, express or implied, shall give to any
Person, other than the parties hereto and thereto and their successors hereunder and thereunder and the Holders of the Debentures, any benefit or any legal or equitable right, remedy or claim under the Indenture, this Supplemental Indenture or the
Debentures. 
 9. Successors. All agreements of the Company, the Guarantor and the Trustee in this Supplemental Indenture shall bind
their respective successors. 
 10. Governing Law. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS
SUPPLEMENTAL INDENTURE WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. 
 11. Effect of Headings. The section headings in this Supplemental Indenture have been inserted for convenience of reference only, are not to be
considered a part of this Supplemental Indenture and shall in no way modify or restrict any of the terms or provisions hereof. 
 12.
Counterparts. The parties hereto may sign multiple counterparts of this Supplemental Indenture. Each signed counterpart shall be deemed an original, but all of them together shall constitute one and the same instrument.

(5) The Company may set any day as the record date for the purpose of determining the Holders entitled to give or take any request, demand,
authorization, direction, notice, consent, waiver or other action, or to vote on any action, authorized or permitted by this Indenture to be 

  

 13 

 
given or taken by Holders. Promptly and in any case not later than ten days after setting a record date, the Company shall notify the Trustee and the Holders
of such record date. If not set by the Company prior to the first solicitation of a Holder made by any Person in respect of any such action, or, in the case of any such vote, prior to such vote, the record date for any such action or vote shall be
the 30th day (or, if later, the date of the most recent list of Holders required to be provided pursuant to Section 15.1) prior to such first solicitation or vote, as the case may be. With regard to any record date, the Holders of Outstanding
Securities on such date (or their duly appointed agents or proxies), and only such Persons, shall be entitled to give or take, or vote on, the relevant action, whether or not such Holders remain Holders after such record date. Notwithstanding the
foregoing, the Company shall not set a record date for, and the provisions of this paragraph shall not apply with respect to, any notice, declaration or direction referred to in the next paragraph. 
 Upon actual receipt by a Responsible Officer of the Trustee from any Holder of (i) any notice of default or breach referred to in
Section 5.1(4), if such default or breach has occurred and is continuing and the Trustee shall not have given such a notice to the Company, (ii) any declaration of acceleration referred to in Section 5.2, if an Event of Default has
occurred and is continuing and the Trustee shall not have given such a declaration to the Company, or (iii) any direction referred to in Section 5.12, if the Trustee shall not have taken the action specified in such direction, then, with
respect to clauses (ii) and (iii), a record date shall automatically and without any action by the Company or the Trustee be set for determining the Holders entitled to join in such declaration or direction, which record date shall be the close
of business on the tenth day (or, if such day is not a Business Day, the first Business Day thereafter) following the day on which the Trustee so receives such declaration or direction, and, with respect to clause (i), the Trustee may set any day as
a record date for the purpose of determining the Holders entitled to join in such notice of default. Promptly after such receipt by the Trustee of any such declaration or direction referred to in clause (ii) or (iii), and promptly after setting
any record date with respect to clause (i), and as soon as practicable thereafter, the Trustee shall notify the Company and the Holders of any such record date so fixed. The Holders on such record date (or their duly appointed agents or proxies),
and only such Persons, shall be entitled to join in such notice, declaration or direction, whether or not such Holders remain Holders after such record date; provided that, unless such notice, declaration or direction shall have become
effective by virtue of Holders of the requisite aggregate principal amount of Securities on such record date (or their duly appointed agents or proxies) having joined therein on or prior to the 90th day after such record date, such notice,
declaration or direction shall automatically and without any action by any Person be canceled and of no further effect. Nothing in this paragraph shall be construed to prevent a Holder (or a duly appointed agent or proxy thereof) from giving, before
or after the expiration of such 90-day period, a notice, declaration or direction contrary to or different from, or, after the expiration of such period, identical to, the notice, declaration or direction to which such record date relates, in which
event a new record date in respect thereof shall be set pursuant to this paragraph. In addition, nothing in this paragraph shall be construed to render ineffective any notice, declaration or direction of the type referred to in this paragraph given
at any time to the Trustee and the Company by Holders (or their duly appointed agents or proxies) of the requisite aggregate principal amount of Securities on the date such notice, declaration or direction is so given. 
 (6) Any request, demand, authorization, direction, notice, consent, election, waiver or other Act of the Holder of any Security shall bind every future
Holder of the same Security and the 

  

 14 

 
Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or
suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security. 
 (7) The provisions of this Section 1.4 are subject to the provisions of Section 9.5. 
 SECTION 1.5
Notices, Etc. to the Trustee and Company. 
 Any request, demand, authorization, direction, notice, consent, election, waiver or other Act of
Holders of Securities or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, 
 (1)
the Trustee by any Holder of Securities or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing by first class mail postage prepaid (registered or certified, return receipt requested) or by
facsimile (receipt confirmed) or delivered by hand or by overnight courier guaranteeing next day delivery, to or with a Responsible Officer of the Trustee and actually received by the Trustee at 555 S.W. Oak Street, PDF-OR-P6TD, Portland, Oregon
97204, Attention: Corporate Trust Services (Merix Corporation 4% Convertible Senior Subordinated Notes due 2013), or at any other address previously furnished in writing by the Trustee, and 
 (2) the Company by the Trustee or by any Holder of Securities shall be sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing, mailed, first-class postage prepaid, or facsimile (receipt confirmed), or delivered by hand or overnight courier, addressed to the Company at 1521 Poplar Lane, Forest Grove, Oregon 97209, Attention: Chief Executive Officer,
Facsimile: (503) 357-1504, or at any other address previously furnished in writing to the Trustee by the Company. 
 All notices to the
Company will be deemed to have been duly given: at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when receipt confirmed, if facsimile; and the next Business Day
after timely delivery to the courier, if delivered by overnight delivery. All notices and communications to the Trustee will be deemed to have been duly given when actually received by a Responsible Officer of the Trustee. 
 SECTION 1.6 Notice to Holders of Securities; Waiver. 
 Except as otherwise expressly provided herein, where this Indenture provides for notice to Holders of Securities of any event, such notice shall be sufficiently given to Holders if in writing and mailed, first-class
postage prepaid, or facsimile (receipt confirmed), or delivered by an overnight delivery service, to each Holder of a Security affected by such event, at the address of such Holder as it appears in the Security Register, not earlier than the
earliest date and not later than the latest date prescribed for the giving of such notice. 
 Neither the failure to mail or deliver such
notice, nor any defect in any notice so mailed or delivered, to any particular Holder of a Security shall affect the sufficiency of such notice with respect to other Holders of Securities. In case by reason of the suspension of regular mail service
or by reason of any other cause it shall be impracticable to give such notice by mail, then such 

  

 15 

 
notification to Holders of Securities as shall be made with the approval of the Trustee shall constitute a sufficient notification to such Holders for every
purpose hereunder. 
 Such notice shall be deemed to have been given when such notice is mailed or delivered to the overnight delivery
service, as applicable, and shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice. 
 Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of
such notice. Waivers of notice by Holders of Securities shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. 
 SECTION 1.7 Effect of Headings and Table of Contents. 
 The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. 
 SECTION 1.8 Successors and Assigns. 
 All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not. All covenants and agreements in this Indenture by the Trustee shall bind its successors and assigns, whether
so expressed or not. 
 SECTION 1.9 Separability Clause. 
 In case any provision in this Indenture or the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby. 
 SECTION 1.10 Benefits of Indenture.

 Except as provided in the next sentence, nothing in this Indenture or in the Securities, express or implied, shall give to any Person,
other than the parties hereto and their successors and assigns hereunder and the Holders of Securities, any benefit or legal or equitable right, remedy or claim under this Indenture. The provisions of Article XIII are intended to be for the benefit
of, and shall be enforceable directly by, the holders of Senior Debt. 
 SECTION 1.11 Governing Law. 
 THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND 
 CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. 
 SECTION 1.12 Legal
Holidays. 
 In any case where any Interest Payment Date, Redemption Date, Repurchase Date or Stated Maturity of any Security or the last day
on which a Holder of a Security has a right to convert its Security shall not be a Business Day at a Place of Payment or Place of Conversion, as 

  

 16 

 
the case may be, then (notwithstanding any other provision of this Indenture or of the Securities) payment of principal of, premium, if any, or interest on,
or the payment of the Redemption Price, or Repurchase Price, or delivery for conversion of, such Security need not be made at such Place of Payment or Place of Conversion, as the case may be, on or by such day, but may be made on or by the next
succeeding Business Day at such Place of Payment or Place of Conversion, as the case may be, with the same force and effect as if made on the Interest Payment Date, Redemption Date or Repurchase Date, or at the Stated Maturity or by such last day
for conversion; provided, however, that in the case that payment is made on such succeeding Business Day, no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date, Repurchase
Date, Stated Maturity or last day for conversion, as the case may be. 
 SECTION 1.13 Conflict With Trust Indenture Act.

 If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act, the Trust Indenture Act shall control.
If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the Indenture provision so modifying or excluding such provision of the Trust Indenture Act shall be deemed to
apply.

 CUSIP NO. 590049 AA 0 
 MERIX CORPORATION, a corporation duly organized and existing under the laws of the State of Oregon (herein called the “Company”, which term
includes any successor Person under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of Sixty Million United States Dollars ($60,000,000 )
(which principal amount may from time to time be increased or decreased to such other principal amounts (which, taken together with the principal amounts of all other Outstanding Securities, shall not exceed $70,000,000) by adjustments made on the
records of the Trustee hereinafter referred to in accordance with the Indenture) on May 15, 2013 and to pay interest thereon, from May 16, 2006, or from the most recent Interest Payment Date (as defined below) to which interest has been
paid or duly provided for, semi-annually in arrears on May 15 and November 15 in each year (each, an “Interest Payment Date”), commencing November 15, 2006, at the rate of 4% per annum, until the principal hereof is
paid, and at the rate of 4% per annum on any overdue principal and premium, if any, and, to the extent permitted by law, on any overdue interest (including Additional Interest, if any). Interest and Additional Interest, if any, will be computed
on the basis of a 360-day year composed of twelve 30-day months and, in the case of an incomplete month, the actual number of days elapsed. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as
provided in the Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the May 1 or
November 1 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Except as otherwise provided in the Indenture, any such interest not so punctually paid or duly provided for will forthwith cease to be
payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such
Defaulted Interest to be fixed by the Company, notice whereof shall be given to Holders of Securities not less than 10 days prior to the Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of
any automated quotation system or securities exchange on which the Securities may be quoted or listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. Payments of principal shall be made upon
the surrender of this Security at the option of the Holder at any office or agency of the Company as may be designated by it for such purpose in the Borough of Manhattan, The City of New York, in such lawful monies of the United States of America as
at the time of payment shall be legal tender for the payment of public and private debts, by United States Dollar check drawn on, or wire transfer to, a United States Dollar account maintained in The City of New York (such a wire transfer to be made
only to a Holder of an aggregate principal amount of Securities in excess of $2,000,000 and only if such Holder shall have furnished wire instructions in writing to the Trustee no later than 15 days prior to the relevant payment date). 

  

 20 

 
Payment of interest on this Security may be made by United States Dollar check mailed to the address of the Person entitled thereto as such address shall
appear in the Security Register, or, upon written application by the Holder to the Security Registrar setting forth wire instructions not later than the relevant Record Date, by transfer to a United States Dollar account maintained in The City of
New York (such a transfer to be made only to a Holder of an aggregate principal amount of Securities in excess of $2,000,000 and only if such Holder shall have furnished wire instructions in writing to the Trustee no later than 15 days prior to the

with respect to any tax, assessment or other governmental charge imposed by any government or any political subdivision or taxing authority thereof or therein. 
 Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof or an Authenticating Agent by the
manual signature of one of their respective authorized signatories, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

 [FORM OF REVERSE OF SECURITY] 
 This Security is one of a duly authorized issue of securities of the Company designated as its “4% Convertible Senior Subordinated Notes due
2013” (herein called the “Securities”), limited in aggregate principal amount to $60,000,000, plus such increases to the extent the Initial Purchaser exercises its option to purchase up to an additional $10,000,000 in aggregate
principal amount of the Securities, issued and to be issued under an Indenture, dated as of May 16, 2006 (herein called the “Indenture”), between the Company and U.S. Bank National Association, as Trustee (herein called the
“Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee, the holders of Senior Debt and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. As provided in the Indenture and subject to
certain limitations therein set forth, Securities are exchangeable for a like aggregate principal amount of Securities of any authorized denominations as requested by the Holder surrendering the same upon surrender of the Security or Securities to
be exchanged, at the Corporate Trust Office of the Trustee. The Trustee upon such surrender by the Holder will issue the new Securities in the requested denominations. 
 No sinking fund is provided for the Securities. 
 Prior to May 20, 2010, the Securities shall not be
redeemable. On or after May 20, 2010 the Company may redeem the Securities if the Closing Price Per Share of the Common Stock exceeds 150% of the Conversion Price then in effect for at least 20 Trading Days within a period of 30
consecutive Trading Days ending on the Trading Day before the date of mailing of the notice of redemption as set forth in Section 11.5 of the Indenture for cash in whole, or from time to time in part (which must be equal to $1,000 or any
integral multiple thereof), at a Redemption Price equal to $1,000 per $1,000 aggregate principal amount of the Securities being redeemed, plus accrued and unpaid interest (including Additional Interest, if any) to, but excluding, the Redemption
Date. Interest installments on Securities whose Stated Maturity is on or prior to such Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, of record at the close of business on the relevant
Record Dates referred to on the face hereof, all as provided in the Indenture. Whenever in this Security there is a reference, in any context, to the principal of any Security as of any time, such reference shall be deemed to include reference to
the Redemption Price payable in respect of such Security to the extent that such Redemption Price is, was or would be so payable at such time, and express mention of the Redemption Price in any provision of this Security shall not be construed as
excluding the Redemption Price so payable in those provisions of this Security when such express mention is not made. 
 In the event of a
redemption of the Securities, the Company will not be required (a) to register the transfer or exchange of Securities for a period of 15 days immediately preceding the date notice is given identifying the serial numbers of the Securities called
for such redemption or (b) to register the transfer or exchange of any Security, or portion thereof, called for redemption. 
  

 23 

 In any case where the due date for the payment of the principal of, premium, if any, interest, including
Additional Interest, if any, on any Security or the last day on which a Holder of a Security has a right to convert their Security shall not be a Business Day, at any Place of Payment or Place of Conversion as the case may be, then payment of
principal, premium, if any, or interest, including Additional Interest, if any, or delivery for conversion of such Security need not be made on or by such date at such place but may be made on or by the next succeeding Business Day at such Place of
Payment or Place of Conversion, as the case may be, with the same force and effect as if made on the date for such payment or the date fixed for redemption or repurchase, or by such last day for conversion, and if the payment is made on such next
succeeding Business Day no interest shall accrue on the amount so payable for the period after such due date. 
 Subject to and upon
compliance with the provisions of the Indenture, the Holder of this Security is entitled, at their option, at any time on or before the close of business on the date of Maturity, or in case this Security or a portion hereof is called for redemption
or the Holder hereof has exercised their right to require the Company to repurchase this Security or such portion hereof, then in respect of this Security until, but (unless the Company defaults in making any payment due upon redemption or
repurchase, as the case may be, in which case the right will terminate at the close of business on the date such default is cured and the Security is redeemed or repurchased, as the case may be) not after, the close of business on the Business Day
immediately preceding the Redemption Date or the Repurchase Date, as the case may be, to convert this Security (or any portion of the aggregate principal amount hereof that is an integral multiple of $1,000, provided that the unconverted
portion of such aggregate principal amount is $1,000 or any integral multiple of $1,000 in excess thereof) into fully paid and nonassessable shares of Common Stock of the Company at an initial Conversion Rate equal to 65.8328 shares for each $1,000
aggregate principal amount of this Security surrendered for conversion (or at the current adjusted Conversion Rate if an adjustment has been made as provided in the Indenture) by surrender of this Security, duly endorsed or assigned to the Company
or in blank and, in case such surrender shall be made during the Record Date Period (except if this Security or portion thereof has been called for redemption or if a Fundamental Change has occurred and an offer to repurchase the Securities is
pending), also accompanied by payment in New York Clearing House or other funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the aggregate principal amount of this Security then being
converted, and also the conversion notice hereon duly executed, to the Company at the Corporate Trust Office of the Trustee, or at such other office or agency of the Company, subject to any laws or regulations applicable thereto and subject to the
right of the Company to terminate the appointment of any Conversion Agent (as defined below) as may be designated by it for such purpose in the Borough of Manhattan, The City of New York, or at such other offices or agencies as the Company may
designate (each a “Conversion Agent”). The interest that is payable on such Interest Payment Date with respect to any Security (or portion thereof, if applicable) that is surrendered for conversion during the Record Date Period shall be
paid to the Holder of such Security as of such Regular Record Date in an amount equal to the interest that would have been payable on such Security if such Security had been converted as of the close of business on such Interest Payment Date.
Subject to the provisions of the preceding sentence and the next paragraph and, in the case of a conversion during the Regular Record Period, to the right of the Holder of this Security (or any Predecessor Security of record as of such Regular
Record Date) to receive the related installment of interest to the extent and under the circumstances provided in the Indenture, no cash payment or adjustment 

  

 24 

 
is to be made on conversion for interest accrued hereon from the Interest Payment Date next preceding the day of conversion, or for dividends on the Common
Stock issued on conversion hereof. The Company shall thereafter deliver to the Holder the fixed number of shares of Common Stock (together with any cash adjustment, as provided in the Indenture) into which this Security is convertible and such
delivery will be deemed to satisfy the Company’s obligation to pay the aggregate principal amount of this Security. No fractions of shares or scrip representing fractions of shares will be issued on conversion, but instead of any fractional
interest (calculated to the nearest 1/100th of a share) the Company shall pay a cash adjustment as provided in the Indenture. The Conversion Rate is subject to adjustment as provided in the Indenture. In addition, the Indenture provides that in case
of certain consolidations or mergers to which the Company is a party (other than a consolidation or merger that does not result in any reclassification, conversion, exchange or cancellation of the Common Stock) or the conveyance, transfer, sale or
lease of all or substantially all of the property and assets of the Company, the Indenture shall be amended, without the consent of any Holders of Securities, so that this Security, if then Outstanding, will be convertible thereafter, during the
period this Security shall be convertible as specified above, only into the kind and amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, transfer, sale or lease by a holder of the number of shares of
Common Stock of the Company into which this Security could have been converted immediately prior to such consolidation, merger, conveyance, transfer, sale or lease (assuming such holder of Common Stock is not a Constituent Person or an Affiliate of
a Constituent Person, or failed to exercise any rights of election and received per share the kind and amount received per share by a plurality of Non-electing Shares). 
 If this Security is a Registrable Security (as defined in the Indenture), then the Holder of this Security (including any Person that has a beneficial interest in this Security) and the Common Stock of the Company
issuable upon conversion hereof is entitled to the benefits of a Registration Rights Agreement, dated as of May 16, 2006, executed by the Company and the Initial Purchaser (as amended from time to time, the “Registration Rights
Agreement”). 
 In accordance with the terms of the Registration Rights Agreement, during any period in which an Event of Default (as
defined in the Registration Rights Agreement) (each, a “Registration Default”) has occurred and is continuing, the Company will pay Additional Interest from and including the day following such Registration Default to but excluding the day
on which such Registration Default has been cured. Additional Interest will be paid semi-annually in arrears, with the first semi-annual payment due on the first Interest Payment Date, as applicable, in respect of the Registrable Securities
following the date on which such Additional Interest begins to accrue, and will accrue at a rate per annum equal to one-quarter of one percent (0.25%) of the aggregate principal amount of the Registrable Securities to and including the 90th day
following such Registration Default and at a rate per annum equal to one-half of one percent (0.50%) thereof from and after the 91st day following such Registration Default. In no event shall the Company be required to pay Additional Interest in
excess of the applicable maximum rate per annum of one-half of one percent (0.50%) set forth above regardless of whether one or multiple Registration Defaults exist. 
 Whenever in this Security there is a reference, in any context, to the payment of interest on, or in respect of, any Security as of any time, such reference shall be deemed to include reference to Additional Interest,
as described in the preceding paragraph, if any, payable in respect 

  

 25 

 
of such Security to the extent that such Additional Interest, if any, is, was or would be so payable at such time, and express mention of Additional
Interest, if any, in any provision of this Security shall not be construed as excluding Additional Interest, if any, so payable in those provisions of this Security when such express mention is not made. 
 If this Security is a Registrable Security and the Holder of this Security (including any Person that has a beneficial interest in this Security) elects
to sell this Security pursuant to the Shelf Registration Statement then, by its acceptance hereof, such Holder of this Security agrees to be bound by the terms of the Registration Rights Agreement relating to the Registrable Securities which are the
subject of such election. 
 If a Fundamental Change occurs, the Holder of this Security, at the Holder’s option, shall have the right,
in accordance with the provisions of the Indenture, to require the Company to repurchase this Security (or any portion of the aggregate principal amount hereof that is at least $1,000 or an integral multiple of $1,000 in excess thereof, provided
that the portion of the aggregate principal amount of this Security to be Outstanding after such repurchase is at least equal to $1,000) for cash at a Repurchase Price equal to 100% of the aggregate principal amount thereof plus interest accrued
to the Repurchase Date, as provided in the Indenture. Whenever in this Security there is a reference, in any context, to the principal of any Security as of any time, such reference shall be deemed to include reference to the Repurchase Price
payable in respect of such Security to the extent that such Repurchase Price is, was or would be so payable at such time, and express mention of the Repurchase Price in any provision of this Security shall not be construed as excluding the
Repurchase Price so payable in those provisions of this Security when such express mention is not made. 
 If a holder surrenders its
Securities (or any portion thereof) for conversion after receipt of a Company Notice in connection with a Fundamental Change and prior to the Repurchase Date, and the Fundamental Change constitutes a specified Fundamental Change defined in the
Indenture, the Company will increase the Conversion Rate as set forth in the Indenture. 
 In the event of a deposit or withdrawal of an
interest in this Security, including an exchange, transfer, redemption, repurchase or conversion of this Security in part only, the Trustee, as custodian of the Depositary, shall make an adjustment on its records to reflect such deposit or
withdrawal in accordance with the Applicable Procedures. 
 The indebtedness evidenced by this Security is, to the extent and in the manner
provided in the Indenture, subordinate and subject in right of payment to the prior payment in full in cash of all Senior Debt of the Company, and this Security is issued subject to such provisions of the Indenture with respect thereto. Each Holder
of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on their behalf to take such action as may be necessary or appropriate to effectuate the subordination so
provided and (c) appoints the Trustee their attorney-in-fact for any and all such purposes. 
 If an Event of Default shall occur and be
continuing, the principal of all the Securities, together with accrued interest to the date of declaration and any premium thereon, may be declared due and payable in the manner and with the effect provided in the Indenture. Upon payment (i) of
the amount of principal so declared due and payable, together with accrued interest to the date of 

  

 26 

 
declaration and any premium thereon, and (ii) of interest on any overdue principal and, to the extent permitted by applicable law, overdue interest and
premium, all of the Company’s obligations in respect of the payment of the principal of and interest on the Securities shall terminate. 
 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by
the Company and the Trustee with either (a) the written consent of the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities, or (b) by the adoption of a resolution, at a meeting of Holders of the
Outstanding Securities at which a quorum is present, by the Holders of at least 66 2/3% in aggregate principal amount of the Outstanding Securities represented and entitled to vote at such meeting. The Indenture also contains provisions permitting
the Holders of specified percentages in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Security or such other Security. Certain modifications or amendments to the Indenture require the consent of
the Holder of each Outstanding Security affected. 
 As provided in and subject to the provisions of the Indenture, the Holder of this
Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice
of a continuing Event of Default, the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and
offered the Trustee security or indemnity reasonably satisfactory to the Trustee and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of the Securities Outstanding a direction inconsistent with such
request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of security or indemnity (or if requested, receipt of security or indemnity). The foregoing shall not apply to any suit
instituted by the Holder of this Security for the enforcement of any payment of principal hereof, premium if any, or interest (including Additional Interest, if any) hereon on or after the respective due dates expressed herein or for the enforcement
of the right to convert this Security as provided in the Indenture. 
 No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair (without the consent of the Holder hereof) the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest (including Additional Interest, if any)
on this Security at the times, places and rate, and in the coin or currency, herein prescribed or to convert this Security as provided in the Indenture. 
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable on the Security Register upon surrender of this Security for registration of transfer at
the Corporate Trust Office of the Trustee or at such other office or 

  

 27 

 
agency of the Company as may be designated by it for such purpose in the Borough of Manhattan, The City of New York (which shall initially be an office or
agency of the Trustee), or at such other offices or agencies as the Company may designate, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the
Holder thereof or their attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees by the
Security Registrar. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee, any Agent and any agent of the Company, the Trustee
or any Agent may treat the Person in whose name such Security is registered as the owner thereof for all purposes, whether or not such Security be overdue, and neither the Company, the Trustee nor any Agent or other such agent shall be affected by
notice to the contrary. 
 No recourse for the payment of the principal (and premium, if any) or interest on this Security and no recourse
under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator,
shareholder, employee, agent, officer or director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any
constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of consideration for the issue hereof, expressly waived and released by the Holder
hereof. 
 THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

 All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

 ARTICLE III 
 THE SECURITIES 
 SECTION 3.1 Title and Terms. 
 The aggregate principal amount of Securities which may be authenticated and delivered under this Indenture is limited to $60,000,000 and shall be
increased to the extent the Initial Purchaser exercises its option to purchase up to an additional $10,000,000 in aggregate principal amount of Securities, such that the total aggregate principal amount of Securities which may be authenticated and
delivered under this Indenture shall not exceed $70,000,000 of Securities from the Company, except for Securities authenticated and delivered pursuant to Section 3.4, 3.5, 3.6, 8.5, 12.2 or 14.2(7) in exchange for, or in lieu of, other
Securities previously authenticated and delivered under this Indenture. 
 (1) The Securities shall be known and designated as the “4%
Convertible Senior Subordinated Notes due 2013” of the Company. The Stated Maturity with respect to the principal of the Securities shall be May 15, 2013 and they shall bear interest on their aggregate principal amount from May 16,
2006, payable semi-annually in arrears on May 15 and November 15 in each year, commencing November 15, 2006, at the rate of 4% per annum until the principal thereof is due and at the rate of 4% per annum on any overdue
principal and, to the extent permitted by law, on any overdue interest; provided, however, that payments shall only be made on a Business Day as provided in Section 1.12. 
 The principal of, premium, if any, and interest (including Additional Interest, if any) on the Securities shall be payable as provided in the form of
Securities set forth in Section 2.2, and the Repurchase Price, and the Redemption Price, shall be payable at such places in the Borough of Manhattan, The City of New York, as are identified in the Company Notice given pursuant to
Section 11.5 or Section 14.2, as appropriate (each location of any Paying Agent in the Borough of Manhattan, The City of New York, is being herein called a “Place of Payment”). 
 The Registrable Securities are entitled to the benefits of the Registration Rights Agreement and in the form of Security set forth in Section 2.2.
The Securities are entitled to the payment of Additional Interest as provided in the Registration Rights Agreement and in the form of Security set forth in Section 2.2. Whenever in this Indenture there is a reference, in any context, to the
payment of interest on, or in respect of, any Security as of any time, such reference shall be deemed to include reference to Additional Interest, if any, payable in respect of such Security to the extent that such Additional Interest, if any, is,
was or would be so payable at such time, and express mention of Additional Interest, if any, in any provision of this Indenture shall not be construed as excluding Additional Interest, if any, so payable in those provisions of this Indenture when
such express mention is not made. 
 The Securities shall be redeemable at the option of the Company at any time on or after May 20,
2010, in whole or in part, subject to the conditions and as otherwise provided in Article XI and in the form of Security set forth in Section 2.2. 
  

 33 

 The Securities shall be convertible as provided in Article XII (any city in which any Conversion
Agent is located being herein called a “Place of Conversion”). 
 The Securities shall be subordinated in right of payment to
Senior Debt of the Company as provided in Article XIII. The Securities shall be subject to repurchase by the Company at the option of the Holders as provided in Article XIV. 
 SECTION 3.2 Denominations. 
 The Securities shall be issuable only in registered form, without coupons, in denominations of $1,000 and integral multiples of $1,000 in excess thereof. 
 SECTION 3.3 Execution, Authentication, Delivery and Dating. 
 The Securities shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the Board, its Chief Executive Officer, its
President, any Vice President (whether or not such title is preceded by any modifier such as “Executive,” “Senior” or the like), and attested by its principal financial officer, Treasurer, Secretary or one of its Assistant
Secretaries. Any such signature may be manual or facsimile. 
 Securities bearing the manual or facsimile signature of individuals who were
at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at
the date of such Securities. 
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver
Securities executed by the Company to the Trustee or to its order for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with such Company Order shall authenticate and
make available for delivery such Securities as in this Indenture provided. 
 Each Security shall be dated the date of its authentication.

 No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature of an authorized signatory, and such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder. 
 SECTION 3.4 Global Securities;
Non-global Securities; Book-entry Provisions. 
 (1) Global Securities 
 (i) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated by the Company
for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture. 
  

 34 

 (ii) Except for exchanges of Global Securities for definitive, Non-global Securities at
the sole discretion of the Company, no Global Security may be exchanged in whole or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary
for such Global Security or a nominee thereof unless (A) such Depositary (i) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency
registered as such under the Exchange Act or announces an intention permanently to cease business or does in fact do so or (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security. In such event,
if a successor Depositary for such Global Security is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such ineligibility, the Company will execute, and the Trustee, upon actual receipt by a
Responsible Officer of an Officers’ Certificate directing the authentication and delivery of Securities and an Opinion of Counsel with respect thereto, will authenticate and deliver pursuant to such instructions, Securities, in any authorized
denominations in an aggregate principal amount equal to the aggregate principal amount of such Global Security in exchange for such Global Security. 
 (iii) If any Global Security is to be exchanged for other Securities or canceled in whole, it shall be surrendered by or on behalf of the Depositary or its nominee to the Trustee, as Security Registrar, for exchange
or cancellation, as provided in this Article III. If any Global Security is to be exchanged for other Securities or canceled in part, or if another Security is to be exchanged in whole or in part for a beneficial interest in any Global
Security, in each case, as provided in Section 3.5, then either (A) such Global Security shall be so surrendered for exchange or cancellation, as provided in this Article III, or (B) the aggregate principal amount thereof shall
be reduced or increased by an amount equal to the portion thereof to be so exchanged or canceled, or equal to the aggregate principal amount of such other Security to be so exchanged for a beneficial interest therein, as the case may be, by means of
an appropriate adjustment made on the records of the Trustee, as Security Registrar, whereupon the Trustee, in accordance with the Applicable Procedures, shall instruct the Depositary or its authorized representative to make a corresponding
adjustment to its records. Upon any such surrender or adjustment of a Global Security, the Trustee shall, subject to Section 3.5(3) and as otherwise provided in this Article III, authenticate and deliver any Securities issuable in exchange
for such Global Security (or any portion thereof) to or upon the order of, and registered in such names as may be directed by, the Depositary or its authorized representative. Upon the request of the Trustee in connection with the occurrence of any
of the events specified in the preceding paragraph, the Company shall promptly make available to the Trustee a reasonable supply of Securities that are not in the form of Global Securities. The Trustee shall be entitled to rely upon any order,
direction or request of the Depositary or its authorized representative which is given or made pursuant to this Article III and the Trustee may request an Officers’ Certificate directing the authentication and delivery of the Securities
and an Opinion of Counsel related thereto. 
 (iv) Every Security authenticated and delivered upon registration of transfer
of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Article III or otherwise, shall be authenticated and delivered in the form of, and shall be, a registered Global Security, unless such
Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof, in which case such Security shall be authenticated and delivered in definitive, fully registered form, without interest coupons.

  

 35 

 (v) The Depositary or its nominee, as registered owner of a Global Security, shall be the
Holder of such Global Security for all purposes under the Indenture and the Securities, and owners of beneficial interests in a Global Security shall hold such interests pursuant to the Applicable Procedures. Accordingly, any such owner’s
beneficial interest in a Global Security will be shown only on, and the transfer of such interest shall be effected only through, records maintained by the Depositary or its nominee or its Agent Members and such owners of beneficial interests in a
Global Security will not be considered the owners or holders thereof. 
 (2) Non-global Securities. Securities issued upon the events
described in Section 3.4(l)(ii) shall be in definitive, fully registered form, without interest coupons, and shall bear the Restricted Securities Legend if and as required by this Indenture. 
 SECTION 3.5 Registration; Registration of Transfer and Exchange; Restrictions on Transfer. 
 (1) The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office referred to as the
“Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Security
Registrar” for the purpose of registering Securities and transfers and exchanges of Securities as herein provided. 
 Subject to the
other provisions of this Section 3.5, upon surrender for registration of transfer of any Security at an office or agency of the Company designated pursuant to Section 10.2 for such purpose, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this
Indenture. 
 At the option of the Holder, and subject to the other provisions of this Section 3.5, Securities may be exchanged for
other Securities of any authorized denomination and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at any such office or agency. Whenever any Securities are so surrendered for exchange, and subject to the
other provisions of this Section 3.5, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities that the Holder making the exchange is entitled to receive. Every Security presented or surrendered for registration
of transfer or for exchange shall (if so required by the Company or the Security Registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company, the Trustee and the Security Registrar, duly
executed by the Holder thereof or its attorney duly authorized in writing. 
 All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Company, evidencing the same debt and entitled to the same benefits under this Indenture as the Securities surrendered upon such registration of transfer or exchange. 
 No service charge shall be made to a Holder for any registration of transfer or exchange of Securities except as provided in Section 3.6, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with 

  

 36 

 
any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.4, 8.5, 12.2 or 14.2 (other than where the shares of
Common Stock are to be issued or delivered in a name other than that of the Holder of the Security) not involving any transfer and other than any stamp and other duties, if any, which may be imposed in connection with any such transfer or exchange
by the United States or any political subdivision thereof or therein, which shall be paid by the Company. 
 In the event of a redemption of
the Securities, neither the Company nor the Securities Registrar will be required (a) to register the transfer of or exchange Securities for a period of 15 days immediately preceding the date notice is given identifying the serial numbers of
the Securities called for such redemption or (b) to register the transfer of or exchange any Security, or portion thereof, called for redemption, except for the unredeemed portion of any Securities being redeemed in part. 
 (2) Certain Transfers and Exchanges. Notwithstanding any other provision of this Indenture or the Securities, transfers and exchanges of
Securities and beneficial interests in a Global Security of the kinds specified in this Section 3.5(2) shall be made only in accordance with this Section 3.5(2). 
 (i) Restricted Global Security to Restricted Non-global Security. In the event that Non-global Securities are to be issued pursuant
to Section 3.4(1)(ii) in connection with any transfer of Securities, such transfer may be effected only in accordance with the provisions of this Clause (2)(i) and subject to the Applicable Procedures. Upon actual receipt by a Responsible
Officer of the Trustee, as Security Registrar, of (A) a Company Order from the Company directing the Trustee, as Security Registrar, to (x) authenticate and deliver pursuant to such Order one or more Securities of the same aggregate
principal amount as the beneficial interest in the Restricted Global Security to be transferred, such instructions to contain the name or names of the designated transferee or transferees, the authorized denomination or denominations of the
Securities to be so issued and appropriate delivery instructions and (y) decrease the beneficial interest of a specified Agent Member’s account in a Restricted Global Security by a specified aggregate principal amount not greater than the
aggregate principal amount of such Restricted Global Security, and (B) such other certifications, legal opinions or other information as the Company or the Trustee may require for any reason, including to confirm that such transfer is being
made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and/or that the transfer is being made pursuant to the terms of this Indenture, then the Trustee, as Security Registrar,
shall decrease the aggregate principal amount of the Restricted Global Security by the specified amount and authenticate and deliver Securities in accordance with such instructions from the Company as provided in Section 3.4(1)(iii).

 (ii) Restricted Non-global Security to Restricted Global Security. If the Holder of a Restricted Security (other
than a Global Security) wishes at any time to transfer all or any portion of such Restricted Security to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Security, such transfer may be
effected only in accordance with the provisions of this Clause (2)(ii) and subject to the Applicable Procedures. Upon actual receipt by a Responsible Officer of the Trustee, as Security Registrar, of (A) such Restricted Security as
provided in Section 3.5(1) and instructions from the Company directing that a beneficial interest in the Restricted Global Security in a specified aggregate principal amount not 

  

 37 

 
greater than the aggregate principal amount of such Security be credited to a specified Agent Member’s account, and (B) a Restricted Securities
Certificate, satisfactory to the Trustee, and duly executed by such Holder or its attorney duly authorized in writing, then the Trustee, as Security Registrar, shall cancel such Restricted Security (and issue a new Restricted Security in respect of
any untransferred portion thereof) as provided in Section 3.5(1) and increase the aggregate principal amount of the Restricted Global Security by the specified aggregate principal amount as provided in Section 3.4(1)(iii). 
 (iii) Exchanges Between Global Security and Non-global Security. A beneficial interest in a Global Security may be exchanged for a
Security that is not a Global Security only as provided in Section 3.4 or only if such exchange occurs in connection with a transfer effected in accordance with Clause 2(i) above, provided that, if such interest is a beneficial interest
in the Restricted Global Security, then such interest shall be exchanged for a Restricted Security (subject in each case to Section 3.5(3)). A Security that is not a Global Security may be exchanged for a beneficial interest in a Global
Security only if such exchange occurs in connection with a transfer effected in accordance with Clause (2)(ii) above. 
 (3)
Securities Act Legends. All Securities issued pursuant to this Indenture, and all Successor Securities, shall bear the Restricted Securities Legend, subject to the following: 
 (i) subject to the following Clauses of this Section 3.5(3), a Security or any portion thereof which is exchanged, upon transfer or
otherwise, for a Global Security or any portion thereof shall bear the Restricted Securities Legend borne by such Global Security for which the Security was exchanged; 
 (ii) subject to the following Clauses of this Section 3.5(3), a new Security that is not a Global Security and is issued in exchange
for another Security (including a Global Security) or any portion thereof, upon transfer or otherwise, shall bear the Restricted Securities Legend borne by the Security for which the new Security was exchanged; 
 (iii) any Securities that are sold or otherwise disposed of pursuant to an effective registration statement under the Securities Act
(including the Shelf Registration Statement), together with their Successor Securities shall not bear a Restricted Securities Legend; the Company shall inform the Trustee in writing of the effective date of any such registration statement
registering the Securities under the Securities Act and shall notify the Trustee in writing at any time when prospectuses must be delivered with respect to Securities to be sold pursuant to such registration statement. Neither the Trustee nor any of
its agents shall be liable, and the Company shall indemnify the Trustee and each such agent, for any action taken or omitted to be taken by it in good faith in accordance with the aforementioned registration statement; 
 (iv) at any time after the Securities may be freely transferred without registration under the Securities Act or without being subject to
transfer restrictions pursuant to the Securities Act, a new Security that does not bear a Restricted Securities Legend may be issued in exchange for or in lieu of a Security (other than a Global Security) or any portion thereof that bears such a
legend if a Responsible Officer of the Trustee has actually received an Unrestricted Securities Certificate, satisfactory to the Trustee and duly executed by, or on behalf of, the Holder of such Security bearing a Restricted Securities Legend or its
attorney duly authorized in writing, 

  

 38 

 
and after such date and receipt of such certificate, the Trustee shall at the direction of the Company in a Company Order authenticate and deliver such new
Security in exchange for or in lieu of such other Security as provided in this Article III; 
 (v) a new Security that
does not bear a Restricted Securities Legend may be issued in exchange for or in lieu of a Security or any portion thereof that bears such a legend if, in the Company’s judgment, placing such a legend upon such new Security is not necessary to
ensure compliance with the registration requirements of the Securities Act, and the Trustee, at the direction of the Company in a Company Order to such effect, shall authenticate and deliver such a new Security as provided in this Article III;
and 
 (vi) notwithstanding the foregoing provisions of this Section 3.5(3), a Successor Security of a Security that does
not bear a Restricted Securities Legend shall not bear such legend unless the Company has reasonable cause to believe that such Successor Security is a “restricted security” within the meaning of Rule 144, in which case the Trustee,
at the direction of the Company in a Company Order to such effect, shall authenticate and deliver a new Security bearing a Restricted Securities Legend in exchange for such Successor Security as provided in this Article III. 
 (4) Any stock certificate representing shares of Common Stock issued upon conversion of the Securities shall bear the Restricted Securities Legend borne
by such Securities, to the extent required by this Indenture, unless such shares of Common Stock have been sold pursuant to a registration statement that has been declared effective under the Securities Act (including the Shelf Registration
Statement) (and that continues to be effective at the time of such transfer) or sold pursuant to Rule 144(k) of the Securities Act, or unless otherwise agreed by the Company in writing with written notice thereof to the transfer agent for the
Common Stock. With respect to the transfer of shares of Common Stock issued upon conversion of the Securities that are restricted hereunder, any deliveries of certificates, legal opinions or other instruments that would be required to be made to the
Security Registrar in the case of a transfer of Securities, as described above, shall instead be made to the transfer agent for the Common Stock. 
 (5) Neither the Trustee, the Paying Agent, the Security Registrar, the Conversion Agent or any other Agent nor any of their respective agents shall (i) have any duty to monitor compliance with or with respect to any federal or state or
other securities or tax laws or (ii) have any duty to obtain documentation on any transfers or exchanges other than as specifically and expressly required hereunder. 
 SECTION 3.6 Mutilated, Destroyed, Lost or Stolen Securities. 
 If any mutilated Security is surrendered to the Trustee (together with such security or indemnity as may be satisfactory to the Company and the Trustee to
fully protect each of them and any Agent or other agent of either of them or any Agent, from any loss, damage, liability, cost or expense which any of them may suffer or incur if the Security is replaced), the Company shall execute and, upon actual
receipt by a Responsible Officer of the Trustee of a Company Request to such effect, the Trustee shall authenticate and deliver in exchange therefor a new Security of like tenor and aggregate principal amount and bearing a number not
contemporaneously outstanding. 
  

 39 

 If there be delivered to the Company and to the Trustee: 
 (1) evidence to their satisfaction of the destruction, loss or theft of any Security, and 
 (2) such security, indemnity bond or other indemnity as may be satisfactory to the Company and the Trustee to fully protect and hold harmless each of
them and any Agent or other agent of either of them or any Agent from any loss, damage, liability, cost or expense which any of them may suffer or incur, if the Security is replaced, 
 then, in the absence of actual notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and, upon actual receipt by a Responsible Officer of the
Trustee of a Company Request to such effect, the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and aggregate principal amount and bearing a number not contemporaneously
Outstanding. If, after the delivery of such new Security, a bona fide purchaser of the original Security in lieu of which such new Security was issued presents for payment or registration such original Security, the Trustee shall be entitled to
recover such new Security from the party to whom it was delivered or any party taking therefrom, except a bona fide purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage,
liability, cost or expense incurred by the Company and the Trustee in connection therewith. 
 In case any Security which has become, or is
about to become, due and payable is submitted for redemption or repurchase pursuant to Article XI or Article XIV, respectively, or is about to be converted into Common Stock pursuant to Article XII shall become mutilated, destroyed, lost or stolen,
the Company in its discretion, but subject to any conversion rights, may, instead of issuing a new Security, pay or authorize the payment of or convert or authorize the conversion of such Security (without surrender thereof, except in the case of a
mutilated Security), upon satisfaction of the conditions set forth in the preceding paragraph. 
 Upon the issuance of any new Security under
this Section 3.6, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto (other than any stamp and other duties, if any, which may be imposed in connection
therewith by the United States or any political subdivision thereof or therein, which shall be paid by the Company) and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
 Every new Security issued pursuant to this Section 3.6 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and such new Security shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities duly issued, authenticated and delivered hereunder. 
 The provisions of this
Section 3.6 are exclusive and shall preclude (to the extent lawful) all other rights and remedies of any Holder with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
  

 40 

 SECTION 3.7 Payment of Interest; Interest Rights Preserved. 
 Subject to the last paragraph of this Section, interest, including Additional Interest, if any, on any Security that is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. 
 Any interest, including Additional Interest, if any, on any Security that is payable, but is not punctually paid or duly provided for, on any Interest
Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in Clause (1) or (2) below: 
 (1) The Company may elect to make payment of any Defaulted
Interest to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on a “Special Record Date” for the payment of such Defaulted Interest, which shall be fixed in the
following manner. The Company shall promptly notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security, the date of the proposed payment and the Special Record Date, and at the same time the Company shall
deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the 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. The Special Record Date for the payment of such Defaulted Interest shall be not more than 15 days and not
less than 10 days prior to the date of the proposed payment and not less than 10 days after the actual receipt by a Responsible Officer of the Trustee of the notice of the proposed payment. The Trustee, in the name and at the expense of the Company,
shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder at such Holder’s address as it appears in the Security Register, not less than
10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities (or
their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2). 
 (2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange
or automated quotation system on which the Securities may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee. 
 Subject to the provisions of
this Section 3.7 and Section 3.5, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which
were carried by such other Security. 
  

 41 

 Interest on any Security that is converted in accordance with Section 12.2 during a Record Date
Period shall be payable in accordance with the provisions of Section 12.2. 
 SECTION 3.8 Persons Deemed Owners.

 Prior to due presentment of a Security for registration of transfer, the Company, the Trustee, the Securities Registrar, any Paying Agent
or Conversion Agent and any other Agent, and any agent of the Company, the Trustee, the Securities Registrar, any Paying Agent or Conversion Agent or any other Agent may treat the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of, premium, if any, and (subject to Section 3.7) interest including any Additional Interest, if any, on such Security and for all other purposes whatsoever, whether or not such
Security be overdue, and none of the Company, the Trustee, the Securities Registrar, any Paying Agent or Conversion Agent nor any other Agent nor any agent of the Company, the Trustee, the Securities Registrar, any Paying Agent or Conversion Agent
or any other Agent, shall be affected by notice to the contrary. No holder of any beneficial interest in any Global Security held on its behalf by a Depositary (including through its nominee) shall have any rights under this Indenture with respect
to such Global Security, and such Depositary (including through its nominee) may be treated by the Company, the Trustee and each Agent and any agent of the Company or the Trustee or any Agent, as the owner of such Global Security for all purposes
whatsoever. None of the Company, the Trustee or any Agent or any agent of the Company or the Trustee or any Agent 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 Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 
 SECTION 3.9 Cancellation. 
 All Securities surrendered for payment, redemption, repurchase, registration of
transfer or exchange or conversion shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Securities so delivered to the Trustee shall be canceled promptly by the Trustee. The Company may at any time deliver to
the Trustee for cancellation any Security which the Company may have acquired in any manner. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section 3.9. The Trustee shall dispose
of all canceled Securities held by the Trustee in accordance with applicable law and its customary practices in effect from time to time. Upon written request of the Company actually received by a Responsible Officer of the Trustee, the Trustee
shall deliver certification of the disposal of all cancelled Securities to the Company. 
 SECTION 3.10 Computation of
Interest. 
 Interest on the Securities (including any Additional Interest) shall be computed on the basis of a 360-day year of twelve 30-day
months and, in the case of an incomplete month, the actual number of days elapsed. 
 SECTION 3.11 CUSIP Numbers.

 The Company in issuing Securities may use CUSIP numbers (if then generally in use) in addition to serial numbers; if so, the Trustee shall
use such CUSIP numbers in addition to serial 

  

 42 

 
numbers in notices of redemption or repurchase as a convenience to Holders; provided that any such notice may state that no representation is made as
to the correctness of such CUSIP numbers either as printed on the Securities or as contained in any notice of a redemption or repurchase and that reliance may be placed only on the serial or other identification numbers printed on the Securities,
and any such redemption or repurchase shall not be affected by any defect in or omission of such CUSIP numbers. 
 ARTICLE IV

 SECTION 5.2 Acceleration of Maturity; Rescission and Annulment. 

If an Event of Default (other than an Event of Default specified in Section 5.1(6) or 5.1(7) with respect to the Company) occurs and is
continuing, then in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities may, subject to the provisions of Article XIII, declare the principal of, premium, if any, and accrued
and unpaid interest (including Additional Interest, if any) on all the Securities to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any such declaration such principal,
premium, if any, and accrued and unpaid interest (including Additional Interest, if any) thereon shall become immediately due and payable. If an Event of Default specified in Section 5.1(6) or 5.1(7) with respect to the Company occurs, the
principal of, premium, if any, and accrued and unpaid interest (including Additional Interest, if any) on, all the Securities shall, subject to the provisions of Article XIII, ipso facto become immediately due and payable without any declaration or
other Act of the Holders or any act on the part of the Trustee. 
 At any time after such declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article V provided, the Holders of a majority in aggregate principal amount of the Outstanding Securities, by written notice to the
Company and the Trustee, may, on behalf of all Holders, rescind and annul such declaration and its consequences if: 
 (1) the Company has
paid or deposited with the Trustee a sum sufficient to pay 
 (i) all overdue interest on all Securities, 
  

 46 

 (ii) the principal of and premium, if any, on any Securities that have become due
otherwise than by such declaration of acceleration and any interest, including Additional Interest, if any, thereon at the rate borne by the Securities, 
 (iii) to the extent permitted by applicable law, interest upon overdue interest at a rate of 4% per annum, and 
 (iv) all sums paid or advanced by the Trustee or any Agent hereunder and the reasonable compensation, expenses, disbursements and advances of each of the Trustee and such Agents and their respective agents and
counsel; 
 (2) all Events of Default, other than the nonpayment of the principal of and any premium, and interest, including Additional
Interest, if any, on, Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13; and 
 (3) such rescission and annulment would not conflict with any judgment or decree issued in appropriate judicial proceedings regarding the payment by the Trustee to the Holders of the amounts referred to in 5.2(1).

 No rescission or annulment referred to above shall affect any subsequent default or impair any right consequent thereon. 
 SECTION 5.3 Collection of Indebtedness and Suits for Enforcement by Trustee.
 The Company covenants that if: 
 (1) default is made in the payment of any interest (including any
Additional Interest, if any), on any Security when it becomes due and payable and such default continues for a period of 30 days, or 
 (2)
default is made in the payment of the principal of or premium, if any, on any Security at the Maturity thereof, the Company will, upon written demand of the Trustee, but subject to the provisions of Article XIII, pay to the Trustee for the benefit
of the Holders of such Securities the whole amount then due and payable on such Securities for principal (and premium, if any), and interest (including any Additional Interest, if any), as applicable, and interest on any overdue principal and
premium, if any, and, to the extent permitted by applicable law, on any overdue interest (including any Additional Interest, if any), at a rate of 4% per annum, and in addition thereto, such further amount as shall be sufficient to cover the
reasonable costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Securities and collect 

  

 47 

 
the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Securities,
wherever situated. 
 If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its
rights and the rights of the Holders of Securities by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 
 SECTION 5.4 Trustee May File Proofs of
Claim.
 In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment,
composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or the creditors of either, the Trustee (irrespective of whether the principal of, and
any interest on, the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest)
shall be entitled and empowered, by intervention in such proceeding or otherwise, 
 (1) to file a proof of claim for the whole amount of
principal, premium, if any, and interest owing and unpaid in respect of the Securities and take such other actions, including participating as a member, voting or otherwise, of any official committee of creditors appointed in such matter, and to
file such other papers or documents, in each of the foregoing cases, as may be necessary or advisable, and to take any and all actions authorized under the Trust Indenture Act, in order to have the claims of the Trustee (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders of Securities allowed in such judicial proceeding, and 
 (2) to collect and receive any moneys or other property payable or deliverable on any such claim and to distribute the same; and any custodian, receiver,
assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder of Securities to make such payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders of Securities to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the
Trustee under Section 6.7. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or
adopt on behalf of any Holder of a Security any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder of
a Security in any such proceeding; provided, however, that the Trustee may, on behalf of such Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee.

  

 48 

 SECTION 5.5 Trustee May Enforce Claims Without Possession of Securities.
 All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the
payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which judgment has been recovered. 
 SECTION 5.6 Application of Money Collected.
 Subject to
Article XIII, any money or property collected or to be applied by the Trustee pursuant to this Article V shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money or
property on account of principal, premium, if any, or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 
 FIRST: To the payment of all amounts due the Trustee under Section 6.7; 
 SECOND: To the payment of the amounts then due and unpaid for principal of, premium, if any, or accrued and unpaid interest (including Additional
Interest, if any) on, the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal,
premium, if any, and accrued and unpaid interest (including Additional Interest), respectively; 
 THIRD: To such other Person or Persons, if
any, to the extent entitled thereto; and 
 FOURTH: Any remaining amounts shall be repaid to the Company. 
 The Trustee shall notify the Company in writing of the payment date or dates fixed by the Trustee pursuant to this Section. 
 SECTION 5.7 Limitation on Suits.
 Subject to Section 5.8
below, no Holder of any Security shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: 
 (1) such Holder has previously given written notice to the Trustee of an Event of Default and such Event of Default is continuing at the time of such
institution; 
 (2) the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities shall have made written
request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
  

 49 

 (3) such Holder or Holders have offered to the Trustee, and if requested, shall have provided to the
Trustee, security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request; 
 (4) the Trustee for 60 days after its actual receipt by a Responsible Officer of such notice under Section 5.7(1), request under 5.7(2) and offer of security or indemnity (or if requested, actual receipt of
security or indemnity) under Section 5.7(3) has failed to institute any such proceeding; and 
 (5) no direction inconsistent with such
written request has been given to the Trustee during such 60 day period by the Holders of a majority in aggregate principal amount of the Outstanding Securities, 
 it being understood and intended that no one or more of such Holders 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 of
such Holders, or to obtain or seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders.

 SECTION 5.8 Unconditional Right of Holders to Receive Principal, Premium and Interest and to Convert.
 Notwithstanding any other provision in this Indenture, but subject to the provisions of Article XIII, the Holder of any Security shall have the right,
which is absolute and unconditional, to receive payment of the principal of, premium, if any, and (subject to Section 3.7) interest (including Additional Interest, if any) on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption or repurchase, on the Redemption Date or Repurchase Date, as the case may be), and to convert such Security in accordance with Article XII, and to institute suit for the enforcement of any such payment
and right to convert, and such rights shall not be impaired without the consent of such Holder. 
 SECTION 5.9 Restoration of Rights and Remedies.

If the Trustee or any Holder of a Security has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has
been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders of Securities
shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and such Holders shall continue as though no such proceeding had been instituted. 
 SECTION 5.10 Rights and Remedies Cumulative.
 Except as
otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.6, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of
Securities is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted 

  

 50 

 
by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 SECTION 5.11 Delay or Omission Not Waiver.
 No delay or omission of the Trustee or of any Holder of any
Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or any acquiescence therein. Every right and remedy given by this Article V or
by law to the Trustee or to the Holders of Securities may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or (subject to the limitations contained in this Indenture) by the Holders of Securities as the case
may be. 
 SECTION 5.12 Control by Holders of Securities.
 Subject to Section 6.3, the Holders of a majority in aggregate principal amount of the Outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on the Trustee, provided that 
 (1) such direction shall not be in conflict with
any rule of law or with this Indenture, and 
 (2) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction, and 
 (3) the Trustee need not take any action that might involve it in personal liability or be unjustly
prejudicial to the Holders of Securities not consenting or that it in good faith believes would otherwise be contrary to applicable law. 
 SECTION 5.13
Waiver of Past Defaults.
 The Holders, either (i) through the written consent of not less than a majority in aggregate principal amount
of the Outstanding Securities or (ii) by the adoption of a resolution, at a meeting of Holders of the Outstanding Securities at which a quorum is present, by the Holders of at least 66-2/3% in aggregate principal amount of the Outstanding
Securities represented at such meeting, may on behalf of the Holders of all the Securities waive any past default hereunder and its consequences, except a default (A) in the payment of the principal of, premium, if any, or interest (including
Additional Interest, if any) on any Security, or (B) in respect of a covenant or provision hereof which under Article VIII cannot be modified or amended without the consent of the Holder of each Outstanding Security affected. 

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 
  

 51 

 SECTION 5.14 Undertaking for Costs.
 All parties to this Indenture agree, and each Holder of any Security 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, suffered or omitted by it as Trustee or otherwise, 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; but the provisions of this Section 5.14 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in aggregate principal amount of the
Outstanding Securities, or to any suit instituted by any Holder of any Security for the enforcement of the payment of the principal of, premium, if any, or interest (including Additional Interest, if any) on any Security on or after the respective
Stated Maturity or Maturities or such other dates when due as expressed herein or in such Security (or, in the case of redemption or repurchase, on or after the Redemption Date or Repurchase Date, as the case may be) or for the enforcement of the
right to convert any Security in accordance with Article XII. 
 SECTION 5.15 Waiver of Stay, Usury or Extension Laws.
 The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, usury or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do
so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede by reason of any such law 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 6.1 Certain Duties and Responsibilities.
 (1) Except during the continuance of an Event of Default, 
 (i) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture with respect to the Securities, and no implied covenants or obligations shall be read into this
Indenture against the Trustee; and 
 (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture, but in the case of any such certificates or opinions
which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they substantially conform to the requirements of this 

  

 52 

 
Indenture, but not to confirm or investigate the accuracy of mathematical calculations or otherwise verify or investigate the facts stated therein or the
contents thereof. 
 (2) In case an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers
vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of its own affairs. 
 (3) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to
act, or its own willful misconduct, except that 
 (i) this paragraph (3) shall not be construed to limit the effect of
paragraph (1) of this Section; 
 (ii) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; 
 (iii)
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 a majority in aggregate principal amount of the Outstanding Securities relating to the

 (iv) no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability
in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if a Responsible Officer of the Trustee shall not have actually received security or indemnity satisfactory to the Trustee against any such risk,
claim, loss, liability, damage, cost or expense. 
 (4) Whether or not therein expressly so 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 6.1.

 Within 90 days after the occurrence of any default hereunder as to which a Responsible Officer of
the Trustee has actually received written notice, the Trustee shall give to all Holders of Securities, in the manner provided in Section 1.6, notice of such default, unless such default shall have been cured or waived; provided,
however, that, except in the case of a default in the payment of the principal of, premium, if any, or interest on any Security, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive
committee or a trust committee of directors or any Responsible Officer of the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders; and provided, further, that in the case of any default of
the character specified in Section 5.1(4), no such notice to Holders of Securities shall be given until at least 60 days after the occurrence thereof or, if applicable, the cure period 

  

 53 

 
specified therein. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or both would

request and rely upon an Officers’ Certificate or Opinion of Counsel; 
 (4) the Trustee may consult with counsel of its selection and
the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 
 (5) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of
the Holders of Securities pursuant to this Indenture, unless such Holders shall have offered, and, if requested by the Trustee, delivered to the Trustee security or indemnity reasonably satisfactory to the Trustee against the risks, claims, losses,
liabilities, damages, costs and expenses which might be incurred by it in compliance with such request or direction; 
 (6) 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, note, coupon, other evidence of indebtedness

the supervision of officers or employees of any of such agents or attorneys; 
 (8) the Company shall deliver an Officers’ Certificate

Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded; 
 (9) the
Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; 
 (10) the Trustee shall not be deemed to have notice or actual knowledge of any default or Event of Default unless a Responsible Officer of the Trustee
has actual knowledge thereof or unless written notice of any event which is in fact such a default or Event of Default is actually received by a Responsible Officer of the Trustee at the Corporate Trust Office of the Trustee and such notice
references the Securities and this Indenture; 
 (11) the rights, privileges, protections, immunities and benefits given to the Trustee,
including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each Agent and each other agent, custodian and other Person employed to act hereunder; and
without limiting the foregoing, the Trustee shall be entitled to the rights and protections afforded to the Trustee pursuant to this Article VI in acting as a Paying Agent, Conversion Agent, or Security Registrar hereunder; and 
 (12) neither the Trustee nor any Agent, nor any agent of any such Person, will have any responsibility for any action taken or not taken by the
Depositary. 
 SECTION 6.4 Not Responsible for Recitals or Issuance of Securities.
 The recitals contained herein and in the Securities (except the Trustee’s certificates of authentication) shall be taken as the statements of the
Company, and neither the Trustee nor any Agent, assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture, of the Securities or of the Common Stock issuable upon the

Authenticating Agent, Paying Agent, Conversion Agent or other Agent, or any such other agent or Affiliate. 
 The Trustee may become and act as trustee under other indentures under which other securities, or certificates of interest or participation in other
securities, of the Company are outstanding in the same manner as if it were not Trustee hereunder. 
 SECTION 6.6 Money Held in Trust.
 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 otherwise agreed in writing with the Company.

Reimbursement.
 The Company agrees: 
 (1) to pay to the Trustee from time to time such compensation as the Company and the Trustee shall from time to time agree in writing for its acceptance of this Indenture and for all services rendered by it hereunder in its various
capacities (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 
 (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee (including costs and expenses of enforcing this Indenture
and defending itself against any claim (whether asserted by the Company, any Holder of Securities or any other Person) or liability in connection with the exercise of any of its powers or duties hereunder) in accordance with any provision of this
Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its own negligence or bad faith; and 
 (3) to fully indemnify each of the Trustee, any Agent and any predecessor of the same (and each of their respective directors, officers, employees and

including the costs, expenses and attorneys’ fees and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. 
 Without limiting any rights available to the Trustee under applicable law, when the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 5.1(6) or Section 5.1(7), the expenses (including the charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of the administration under any
applicable Federal or state bankruptcy, insolvency or other similar law. 
 The provisions of this Section shall survive the termination
or satisfaction and discharge of this Indenture or the payment in full of the Securities or the earlier resignation or removal of the Trustee. 
  

 56 

 SECTION 6.8 Corporate Trustee Required; Eligibility.
 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, having (or be
part of a holding company group with) a combined capital and surplus of at least $50,000,000, subject to supervision or examination by federal or state authority, and in good standing. The Trustee or an Affiliate of the Trustee shall maintain an
established place of business in the Borough of Manhattan, The City of New York. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. The Trustee shall not be an obligor upon the
Securities or an Affiliate of any obligor thereon. 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 VI and a successor shall be appointed pursuant to Section 6.9. 
 SECTION 6.9 Resignation and Removal; Appointment of Successor.

(1) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article VI shall become effective until
the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 6.10. 
 (2) The
Trustee may resign at any time by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.10 shall not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may, at the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor Trustee. 
 (3) The Trustee may be removed at any time by an Act of the Holders of a majority in aggregate principal amount of the Outstanding Securities, delivered to the Trustee and the Company. If the instrument of acceptance
by a successor Trustee required by Section 6.10 shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the removed Trustee may, at the expense of the Company, petition any court of competent
jurisdiction for the appointment of a successor Trustee. 
 (4) If at any time: 
 (i) the Trustee shall cease to be eligible under Section 6.8 and shall fail to resign after written request therefor by the Company
or by any Holder of a Security who has been a bona fide Holder of a Security for at least six months, or 
 (ii) 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 (i) the Company by a Board Resolution may remove the Trustee, or
(ii) subject to Section 5.14, any Holder of a Security who has been a bona fide Holder of a 

  

 57 

 
Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of
the Trustee and the appointment of a successor Trustee. 
 (5) If the Trustee shall resign, be removed or become incapable of acting, or if a
vacancy shall occur in the office of Trustee for any cause, the Company, by a Board Resolution, shall promptly appoint a successor Trustee and shall comply with the applicable requirements of this Section and Section 6.10. If, within one
year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in aggregate principal amount of the Outstanding Securities delivered to the Company
and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 6.10, become the successor Trustee and supersede the successor
Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders of Securities and accepted appointment in the manner required by this Section and Section 6.10, any Holder of a Security
who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee. 
 (6) The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders of
Securities in the manner provided in Section 1.6. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. 
 SECTION 6.10 Acceptance of Appointment by Successor.
 Every successor Trustee appointed hereunder shall execute, acknowledge and
deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon
request of any such successor Trustee, the Company and the retiring Trustee shall execute any and all instruments to more fully and with more certainty vest in and confirm to such successor Trustee all such rights, powers and trusts. 
 No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be eligible under this Article VI.

 SECTION 6.11 Merger, Conversion, Consolidation or Succession to Business. 
 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party,
or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee (including the trust created by this Indenture), shall be the 

  

 58 

 
successor of the Trustee hereunder, provided such corporation shall be otherwise eligible under this Article VI, without the execution or filing of
any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. 
 SECTION 6.12 Authenticating Agents.
 The Trustee may, upon
notice to the Company, appoint an “Authenticating Agent” or Agents reasonably acceptable to the Company with respect to the Securities, which Authenticating Agent shall be authorized to act on behalf of the Trustee to authenticate
Securities issued upon exchange or substitution pursuant to this Indenture. 
 Securities authenticated by an Authenticating Agent shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder, and every reference in this Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee’s certificate of authentication shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be subject to acceptance not to be unreasonably withheld by the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the
District of Columbia, authorized under such laws to act as Authenticating Agent and subject to supervision or examination by government or other fiscal authority. If at any time an Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section 6.12, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section 6.12. 
 Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all the corporate agency or corporate trust business of an Authenticating Agent (including the authenticating agency contemplated by this Indenture), shall
continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section 6.12, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating
Agent. 
 An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may
at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon actual receipt by a Responsible Officer of the Trustee of such a notice of resignation or upon such a
termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 6.12, the Trustee may appoint a successor Authenticating Agent which shall be subject to acceptance not
to be unreasonably withheld by the Company. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally
named as an Authenticating Agent. No 

  

 59 

 
successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section 6.12. 
 The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section 6.12.

 If an Authenticating Agent is appointed with respect to the Securities pursuant to this Section 6.12, the Securities may have
endorsed thereon, in addition to or in lieu of the Trustee’s certification of authentication, an alternative certificate of authentication in the following form: 
 This is one of the Securities referred to in the within-mentioned Indenture.

or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. 
 SECTION 6.14 Preferential Collection of Claims Against Company.

and an Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture comply with this Article
VII and that all conditions precedent herein provided for relating to such transaction have been complied with, together with any documents required under Section 8.3. 
 SECTION 7.2 Successor Substituted.

successor Person formed by such consolidation or into or with which the Company is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor Person had been named as the Company herein, and thereafter, except in the case of a lease, the predecessor Person shall be relieved of all obligations and covenants under this Indenture and

will not, in the aggregate, have a material adverse impact on the Company and its Subsidiaries, taken as a whole, or (B) if the amount, applicability or validity is being contested in good faith by appropriate proceedings. 
 SECTION 10.6 Statement by Officers as to Default. 
 The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate, stating whether or not, to the best knowledge of

 ARTICLE XI 
 REDEMPTION OF SECURITIES 
 SECTION 11.1 Right of Redemption. 
 Prior to May 20, 2010, the Securities shall not be redeemable. On or after May 20, 2010 the Company may redeem the Securities if the Closing
Price Per Share of the Common Stock exceeds 150% of the Conversion Price then in effect for at least 20 Trading Days within a period of 30 consecutive Trading Days ending on the Trading Day before the date of mailing of the notice of redemption
as set forth in Section 11.5 hereof for cash in whole, or from time to time in part (which must be equal to $1,000 or any integral multiple thereof), at a Redemption Price equal to $1,000 per $1,000 aggregate principal amount of the Securities
being redeemed, plus accrued and unpaid interest (including Additional Interest, if any) to, but excluding, the Redemption Date. Whenever in this Indenture (including Sections 2.2, 3.1, 5.1(1) and 5.8) there is a reference, in any context, to the
principal of any Security as of any time, such reference shall be deemed to include reference to the Redemption Price payable in respect of such Security to the extent that such Redemption Price is, was or would be so payable at such time, and
express mention of the Redemption Price in any provision of this Indenture shall not be construed as excluding the Redemption Price in those provisions of this Indenture when such express mention is not made. 
 Interest installments on Securities whose Stated Maturity is on or prior to a Redemption Date will be payable to the Holders of such Securities, or one
or more Predecessor Securities, of record at the close of business on the relevant Record Dates. 
 Securities or portions of the Securities
called for redemption shall be convertible by the Holder in accordance with the provisions of Article XII until the close of business on the Business Day prior to the Redemption Date. 
  

 71 

 SECTION 11.2 Applicability of Article. 
 Redemption of Securities at the election of the Company or otherwise, as permitted or required by any provision of the Securities or this Indenture, shall
be made in accordance with such provision and this Article XI. 
 SECTION 11.3 Election to Redeem; Notice to Trustee.

 The election of the Company to redeem any Securities shall be evidenced by a Board Resolution. Subject to Section 11.5, in case of any
redemption at the election of the Company of any of the Securities, the Company shall, at least 30 days but no more than 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee in writing of such Redemption Date. 
 SECTION 11.4 Selection by Trustee of Securities to Be Redeemed.

 If less than all the Securities are to be redeemed, the particular Securities to be redeemed shall be selected by the Trustee within five
Business Days after the actual receipt by a Responsible Officer of the Trustee the notice described in Section 11.3, from the Outstanding Securities not previously called for redemption, on a pro rata basis, by lot or by such other method as
the Trustee may deem fair and appropriate. 
 If any Security selected for partial redemption is converted in part before termination of the
conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted during a selection of
Securities to be redeemed may be treated by the Trustee as Outstanding for the purpose of such selection. The Trustee shall notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for
partial redemption, the aggregate principal amount thereof to be redeemed. 
 For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the aggregate principal amount of such Securities which has been or is
to be redeemed. 
 SECTION 11.5 Notice of Redemption. 
 Notice of redemption shall be given in the manner provided in Section 1.6 to the Holders of Securities to be redeemed not less than 30 nor more

Redemption Price, and accrued interest, if any (including Additional Interest, if any), to, but excluding, the Redemption Date, 
  

 72 

 (3) if less than all Outstanding Securities are to be redeemed, the aggregate principal amount of
Securities to be redeemed and the aggregate principal amount of Securities which will be outstanding after such partial redemption, 
 (4)
that on the Redemption Date the Redemption Price, and accrued but unpaid interest, if any (including Additional Interest, if any), to, but excluding, the Redemption Date, will become due and payable upon each such Security to be redeemed, and that
interest thereon shall cease to accrue on and after said date, 
 (5) the Conversion Rate, the date on which the right to convert the
Securities to be redeemed will terminate and the places where such Securities may be surrendered for conversion, 
 (6) the place or places
where such Securities are to be surrendered for payment of the Redemption Price and accrued interest, if any (including Additional Interest, if any), to, but excluding, the Redemption Date, and 
 (7) that no representation is made as to the correctness or accuracy of the CUSIP number that is listed in such notice or printed on the Securities.

 In case of a partial redemption, the notice shall specify the serial and CUSIP numbers (if any) and the portions thereof called for
redemption and that transfers and exchanges may occur on or prior to the Redemption Date. 
 Notice of redemption of Securities to be
redeemed at the election of the Company shall be given by the Company or, at the Company’s written request, by the Trustee in the name of and at the expense of the Company; provided that, in the event the Trustee is to give such notice,
the Company has delivered to the Trustee at least 45 days prior to the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee) a Company Order requesting the Trustee to give such notice and setting forth all the information to
be included in such notice including information required by this Section 11.5. 
 SECTION 11.6 Deposit of Redemption
Price. 
 On or prior to 10:00 a.m. (New York City time) on the Redemption Date, the Company shall deposit with the Trustee (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.3) an amount of money (which shall be in immediately available funds on such Redemption Date) sufficient to pay the Redemption Price of, and
(except if the Redemption Date shall be an Interest Payment Date) accrued interest (including Additional Interest, if any) to, but excluding, the Redemption Date on, all the Securities which are to be redeemed on that date other than any Securities
called for redemption on that date which have been converted prior to the date of such deposit. 
 If any Security called for redemption is
converted, any money deposited with the Trustee or so segregated and held in trust for the redemption of such Security shall (subject to any right of the Holder of such Security or any Predecessor Security to receive interest as provided in the last
paragraph of Section 3.7) be paid to the Company or, if then held by the Company, shall be discharged from such trust. 
  

 73 

 SECTION 11.7 Securities Payable on Redemption Date. 
 Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified and from and after such date (unless the Company shall default in the payment of the Redemption Price, including accrued interest) such Securities shall cease to bear interest. Upon surrender of any Security for
redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price together with accrued and unpaid interest (including Additional Interest, if any) to, but excluding, the Redemption Date, provided,
however, that installments of interest on Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the relevant Record
Date according to their terms and the provisions of Section 3.7. 
 If any Security called for redemption shall not be so paid on the
Redemption Date, the aggregate principal amount of, premium, if any, and, to the extent permitted by applicable law, accrued interest (including Additional Interest, if any), on such Security shall, until paid, bear interest from the Redemption Date
at a rate of 4% per annum and such Security shall remain convertible until the Redemption Price of such Security (or portion thereof, as the case may be) shall have been paid or duly provided for. 
 Any Security that is to be redeemed only in part shall be surrendered at the Corporate Trust Office or an office or agency of the Company designated for
that purpose pursuant to Section 10.2 (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or its
attorney duly authorized in writing), and the Company shall execute, and, upon its actual receipt by a Responsible Officer of a Company Order to such effect, the Trustee shall authenticate and make available for delivery to the Holder of such
Security without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so
surrendered. 
 SECTION 11.8 Conversion Arrangement on Call for Redemption. 
 In connection with any redemption of Securities, the Company may arrange for the purchase and conversion of any Securities by an agreement with one or
more investment bankers or other purchasers (the “Purchasers”) to purchase such Securities by paying to the Trustee in trust for the Holders, on or before 10:00 a.m. (New York City time) on the Redemption Date, an amount not less than the
applicable Redemption Price, together with interest accrued to, but excluding, the Redemption Date of such Securities. Notwithstanding anything to the contrary contained in this Article XI, the obligation of the Company to pay the Redemption
Price, together with interest accrued to, but excluding, the Redemption Date shall be deemed to be satisfied and discharged to the extent such amount is so paid by such Purchasers. If such an agreement is entered into (a copy of which shall be filed
with the Trustee prior to the close of business on the Business Day immediately prior to the Redemption Date), any Securities called for redemption that are not duly surrendered for conversion by the Holders thereof may, at the option of the
Company, be deemed, to the fullest extent permitted by law, and consistent with any agreement or agreements with such Purchasers, to be acquired by such Purchasers from such Holders and 

  

 74 

 
(notwithstanding anything to the contrary contained in Article XII) surrendered by such Purchasers for conversion, all as of immediately prior to the
close of business on the Redemption Date (and the right to convert any such Securities shall be extended through such time), subject to payment of the above amount as aforesaid. At the direction of the Company, pursuant to a written Company Order,
the Trustee shall hold and dispose of any such amount paid to it by the Purchasers to the Holders in the same manner as it would monies deposited with it by the Company for the redemption of Securities. Without the Trustee’s prior written
consent expressly authorizing a change, no arrangement between the Company and such Purchasers for the purchase and conversion of any Securities shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the
Trustee as set forth in this Indenture, and the Company agrees to indemnify the Trustee from, and hold it harmless against, any loss, liability or expense arising out of or in connection with any such arrangement for the purchase and conversion of
any Securities between the Company and such Purchasers, including the costs and expenses, including reasonable legal fees, incurred by the Trustee in the defense of any claim or liability arising out of or in connection with the exercise or
performance of any of its powers, duties, responsibilities or obligations under this Indenture. 
 ARTICLE XII 
 CONVERSION OF SECURITIES 
 SECTION 12.1 Conversion Right and Conversion Rate. 
 Subject to and upon compliance with the provisions of this Article XII, at the
option of the Holder thereof, any Security may be converted, in whole or in part, into fully paid and nonassessable shares (calculated as to each conversion to the nearest 1/100th of a share) of Common Stock of the Company at the Conversion Rate,
determined as hereinafter provided, in effect at the time of conversion. Such conversion right shall commence on the Issue Date and expire at the close of business on the date of Maturity, subject, in the case of conversion of any Global Security,
to any Applicable Procedures. In case a Security or portion thereof is called for redemption at the election of the Company or the Holder thereof exercises its right to require the Company to repurchase the Security, such conversion right in respect
of the Security, or portion thereof so called for redemption or submitted for repurchase, shall expire at the close of business on the Business Day immediately preceding the Redemption Date or the Repurchase Date, as the case may be, unless the
Company defaults in making the payment due upon redemption or repurchase, as the case may be, in which case the conversion right will terminate at the close of business on the date such default is cured and the Securities are redeemed or
repurchased, as the case may be (in each case subject as aforesaid to any Applicable Procedures with respect to any Global Security). 
 If a
holder surrenders its Securities (or any portion thereof) for conversion after receipt of a Company Notice in connection with a Fundamental Change and prior to the Repurchase Date, the Company will make an adjustment to the Conversion Rate to the
shares of Common Stock deliverable upon conversion of the Securities in accordance with Section 12.4(14). 
 The rate at which shares of
Common Stock shall be delivered upon conversion (herein called the “Conversion Rate”) shall be initially equal to 65.8328 shares for each $1,000 aggregate 

  

 75 

 
principal amount of Securities. The Conversion Rate shall be adjusted in certain instances as provided in this Article XII. All calculations under this
Article XII shall be made to the nearest 1/10th cent or to the nearest 1/10,000ths of a share, as the case may be. 
 SECTION 12.2 Exercise of Conversion Right. 
 In order to exercise the Conversion Right, the Holder of any Security to be converted
shall surrender such Security, duly endorsed or assigned to the Company or in blank, at any office or agency of the Company maintained for that purpose pursuant to Section 10.2, accompanied by a duly signed conversion notice substantially in
the form set forth in Section 2.5 stating that the Holder elects to convert such Security or, if less than the entire aggregate principal amount thereof is to be converted, the portion thereof to be converted. Each Security surrendered for
conversion (in whole or in part) during the Record Date Period shall (except in the case of any Security or portion thereof which has been called for redemption or if a Fundamental Change has occurred and an offer to repurchase the Securities is
pending) be accompanied by payment to the Trustee in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest payable (including Additional Interest, if any) on such Interest Payment Date on the
aggregate principal amount of such Security (or part thereof, as the case may be) being surrendered for conversion. The interest (including Additional Interest, if any) so payable on such Interest Payment Date with respect to any Security (or
portion thereof, if applicable) that is surrendered for conversion during the Record Date Period shall be paid to the Holder of such Security as of such Regular Record Date in an amount equal to the interest (including Additional Interest, if any)
that would have been payable on such Security if such Security had been converted as of the close of business on such Interest Payment Date. Interest (including Additional Interest, if any) payable on any Interest Payment Date in respect of any
Security surrendered for conversion on or after such Interest Payment Date shall be paid to the Holder of such Security as of the Regular Record Date next preceding such Interest Payment Date, notwithstanding the exercise of the right of conversion.
Except as provided in this paragraph or in Section 11.1 and subject to the last paragraph of Section 3.7, no cash payment or adjustment shall be made upon any conversion on account of any interest (including Additional Interest, if any)
accrued from the Interest Payment Date next preceding the conversion date, in respect of any Security (or part thereof, as the case may be) surrendered for conversion, or on account of any dividends on the Common Stock issued upon conversion. The
Company’s delivery to the Holder of the number of shares of Common Stock (and cash in lieu of fractions thereof, as provided in this Indenture) into which a Security is convertible will be deemed to satisfy the Company’s obligation to pay
the aggregate principal amount of the Security. 
 Securities shall be deemed to have been converted immediately prior to the close of
business on the day of surrender of such Securities for conversion in accordance with the foregoing provisions, and at such time the rights of the Holders of such Securities as Holders shall cease, and the Person or Persons entitled to receive the
Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such Common Stock at such time. As promptly as practicable on or after the conversion date, the Company shall issue and deliver to the
Trustee, for delivery to the Holder, a certificate or certificates for the number of full shares of Common Stock issuable upon conversion, together with payment in lieu of any fraction of a share, as provided in Section 12.3. The Company shall
determine such number of shares and the amounts of the required cash with respect to any fractional share, and shall set forth such 

  

 76 

 
information in an Officers’ Certificate delivered to the Conversion Agent and the Trustee. The Conversion Agent shall have no duties under this Article
XII unless and until it has actually received such Officers’ Certificate. In the event the Trustee is no longer the Conversion Agent, the Trustee will deliver the certificate or certificates for the number of full shares of Common Stock
issuable upon conversion, together with payment in lieu of any fraction of a share, as provided in Section 12.3, to the Conversion Agent for delivery to the Holder. 
 All shares of Common Stock delivered upon such conversion of Restricted Securities shall bear restrictive legends substantially in the form of the legends required to be set forth on the Restricted Securities pursuant
to Section 3.5 and shall be subject to the restrictions on transfer provided in such legends. Neither the Trustee nor any agent maintained for the purpose of such conversion shall have any responsibility for the inclusion or content of any such
restrictive legends on such Common Stock; provided, however, that the Trustee or any agent maintained for the purpose of such conversion shall have provided, to the Company or to the Company’s transfer agent for such Common Stock, prior
to or concurrently with a request to the Company to deliver such Common Stock, written notice that the Securities delivered for conversion are Restricted Securities. 
 In the case of any Security which is converted in part only, upon such conversion the Company shall execute and, upon Company Order to such effect, the Trustee shall authenticate and deliver to the Holder thereof, at
the expense of the Company, a new Security or Securities of authorized denominations in an aggregate principal amount equal to the unconverted portion of the aggregate principal amount of such Security. A Security may be converted in part, but only
if the aggregate principal amount of such Security to be converted is any integral multiple of $1,000 and the aggregate principal amount of such security to remain Outstanding after such conversion is equal to $1,000 or any integral multiple of
$1,000 in excess thereof. 
 If shares of Common Stock to be issued upon conversion of a Restricted Security, or Securities to be issued upon
conversion of a Restricted Security in part only, are to be registered in a name other than that of the beneficial owner of such Restricted Security, then such Holder must deliver to the Conversion Agent a Surrender Certificate, dated the date of
surrender of such Restricted Security and signed by such beneficial owner, as to compliance with the restrictions on transfer applicable to such Restricted Security. Neither the Trustee nor any Conversion Agent, Registrar or Transfer Agent shall be
required to register in a name other than that of the beneficial owner, shares of Common Stock or Securities issued upon conversion of any such Restricted Security not so accompanied by a properly completed Surrender Certificate. 
 SECTION 12.3 Fractions of Shares. 
 No fractional shares of Common Stock shall be issued upon conversion of any Security or Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be
issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock that would otherwise be issuable upon
conversion of any Security or Securities (or specified portions thereof), the Company shall calculate and pay a cash adjustment in respect of such fraction (calculated to the 

  

 77 

 
nearest 1/100th of a share) in an amount equal to the same fraction of the Closing Price Per Share on the last Trading Day prior to the day of conversion.

 SECTION 12.4 Adjustment of Conversion Rate. 
 The Conversion Rate shall be subject to adjustments from time to time as follows: 
 (1) In case the Company
shall pay or make a dividend or other distribution on shares of Common Stock payable in shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the date fixed for the determination of shareholders
entitled to receive such dividend or other distribution shall be increased by dividing such Conversion Rate by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for
such determination and the denominator shall be the sum of such number of shares of Common Stock outstanding at the close of business on the date fixed for such determination and the total number of shares of Common Stock constituting such dividend
or other distribution, such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. If, after any such date fixed for determination, any dividend or distribution is not in
fact paid, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would have been in effect if such determination date had
not been fixed. For the purposes of this paragraph (1), 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. 
 (2) In case the Company shall issue rights, options or warrants to all holders of its Common Stock (other than rights issued pursuant to the Rights Plan
(as defined in paragraph (13) of this Section 12.4), except as specified in paragraph (13) of this Section 12.4) entitling them for a period of not more than 60 days to subscribe for or purchase shares of Common Stock at a price
per share less than the current market price per share (determined as provided in paragraph (8) of this Section 12.4) of the Common Stock on the date fixed for the determination of shareholders entitled to receive such rights, options or
warrants (other than any rights, options or warrants that by their terms will also be issued to any Holder upon conversion of a Security into shares of Common Stock without any action required by the Company or any other Person), the Conversion Rate
in effect at the opening of business on the day following the date fixed for such determination shall be increased by dividing such Conversion Rate by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the
close of business on the date fixed for such determination plus the number of shares of Common Stock that the aggregate offering price of the total number of shares of Common Stock so offered for subscription or purchase would purchase at such
current market price and the denominator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock so offered for subscription or purchase,
such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. If, after any such date fixed for determination, any such rights, options or warrants are not in fact issued, or
are not exercised prior to the expiration thereof, the Conversion Rate shall be immediately readjusted, effective as of the date such rights, options or warrants 

  

 78 

 
expire, or the date the Board of Directors determines not to issue such rights, options or warrants, to the Conversion Rate that would have been in effect if
the unexercised rights, options or warrants had never been granted or such determination date had not been fixed, as the case may be. For the purposes of this paragraph (2), 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 issue any rights, options or warrants in respect of
shares of Common Stock held in the treasury of the Company. 
 (3) In case outstanding shares of Common Stock shall be subdivided into a
greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and, conversely, in case outstanding
shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision or combination becomes effective shall be
proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. 
 (4) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness, shares of any class
of capital stock or other property (including cash or assets or securities, but excluding (i) any rights, options or warrants referred to in paragraph (2) of this Section, (ii) any dividend or distribution paid exclusively in cash
referred to in paragraph (5) of this Section, (iii) any dividend or distribution referred to in paragraph (1) of this Section, and (iv) any rights issued pursuant to the Rights Plan (as defined in paragraph (13) of this
Section 12.4) except as specified in paragraph (13) of this Section 12.4), the Conversion Rate shall be adjusted so that the same shall equal the rate determined by dividing the Conversion Rate in effect immediately prior to the close
of business on the date fixed for the determination of shareholders entitled to receive such distribution by a fraction of which the numerator shall be the current market price per share (determined as provided in paragraph (8) of this
Section 12.4) of the Common Stock on the date fixed for such determination less the then fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution filed with the
Trustee) of the portion of the evidences of indebtedness, shares of any class of capital stock or other property so distributed applicable to one share of Common Stock and the denominator shall be such current market price per share of the Common
Stock, such adjustment to become effective immediately prior to the opening of business on the day following the date fixed for the determination of shareholders entitled to receive such distribution. If after any such date fixed for determination,
any such distribution is not in fact made, the Conversion Rate shall be immediately readjusted, effective as of the date of the Board of Directors determines not to make such distribution, to the Conversion Rate that would have been in effect if
such determination date had not been fixed. 
 (5) In case the Company shall, by dividend or otherwise, make one or more dividends or
distributions in cash during any fiscal quarter of the Company to all or substantially all holders of its Common Stock (other than in connection with the Company’s liquidation, dissolution or winding up), then in such case the Conversion Rate
shall be adjusted so that the same shall equal the rate determined by dividing such Conversion Rate in effect immediately prior to the close of 

  

 79 

 
business on such date fixed for determination by a fraction the numerator of which shall be equal to the current market price per share (determined as
provided in paragraph (8) of this Section 12.4) of the Common Stock and the denominator of which shall be equal to such current market price per share of the Common Stock plus the amount per share of such dividend or distribution. The
adjustment will be made successively whenever any such event occurs. 
 (6) In case the Company or any Subsidiary purchases all or any
portion of the Common Stock and the cash and the fair market value of any other consideration included in the payment per share of Common Stock exceeds the current market price per share of the Common Stock immediately prior to contracting to
purchase such Common Stock, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to close of business on the date of such purchase or purchases of
Common Stock are made by the sum of (i) one plus (ii) the quotient of (x) the product of the amount by which the cash and fair market value of any other consideration included in the payment per share of Common Stock exceeds the
current market price per share of Common Stock immediately prior to contracting to purchase such Common Stock, and the number of shares of Common Stock purchased, over (y) the product of the current market price per share of Common Stock
immediately prior to contracting to purchase such Common Stock and the total number of shares of Common Stock outstanding immediately prior to contracting to purchase such Common Stock, such adjustment to become effective immediately after the
opening of business on the day following the date of such purchase. For purposes of the preceding sentence only current market price means, with respect to the Common Stock, at any time, (i) the last reported sale price regular way on the
Nasdaq National Market or, (ii) if the Common Stock is not listed on the Nasdaq National Market, the last reported sale price regular way per share or, in case no such reported sale takes place on such day, the average of the reported closing
bid and asked prices regular way on the day prior to such purchase, in either case, on the principal national securities exchange on which the Common Stock is listed or admitted to trading, or (iii) if the Common Stock is not listed on the
Nasdaq National Market or listed or admitted to trading on any national securities exchange, the average of the bid prices in the over-the-counter market as furnished by any New York Stock Exchange member firm selected from time to time by the
Company for that purpose. In the event of a tender offer in which the cash and the fair market value of any other consideration included in the payment per share of Common Stock exceeds the current market price per share (determined as provided in
paragraph (8) of this Section 12.4) of the Common Stock on the Trading Day next succeeding the last day tenders could have been made pursuant to such tender offer (as it may be amended), the Conversion Rate shall be adjusted so that the
same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to close of business on the Trading Day next succeeding the last day tenders could have been made pursuant to such tender offer (as it may be
amended) (provided that the Conversion Rate in effect at such time shall not include the adjustment provided for in this sentence) by the sum of (i) one plus (ii) the quotient of (x) the product of the amount by which the cash
and fair market value of any other consideration included in the payment per share of Common Stock exceeds current market price per share (determined as provided in paragraph (8) of this Section 12.4) of the Common Stock on the Trading Day
next succeeding the last day tenders could have been made pursuant to such tender offer (as it may be amended), and the number of shares of Common Stock validly tendered and not withdrawn, over (y) the product of current market price per share
(determined as provided in paragraph (8) of this Section 12.4) of the Common Stock on the Trading Day next succeeding the last day tenders could have been made pursuant to such tender 

  

 80 

 
offer (as it may be amended) and the total number of shares of Common Stock outstanding (including shares of Common Stock validly tendered and not withdrawn)
immediately prior to the last day tenders could have been made pursuant to such tender offer (as it may be amended), such adjustment to become effective immediately prior to the opening of business on the Trading Day next succeeding the last day
tenders could have been made pursuant to such tender offer (as it may be amended). If the Company is obligated to purchase shares of the Common Stock pursuant to any such tender offer, but the Company is permanently prevented by applicable law from
effecting any or all such purchases or any or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate which would have been in effect based on the number of shares actually purchased. 
 (7) The reclassification of Common Stock into securities other than Common Stock (other than any reclassification upon a consolidation or merger to which
Section 12.11 applies) shall be deemed to involve (a) a distribution of such securities other than Common Stock to all holders of Common Stock (and the effective date of such reclassification shall be deemed to be “the date fixed for
the determination of shareholders entitled to receive such distribution” and “the date fixed for such determination” within the meaning of paragraph (4) of this Section), and (b) a subdivision or combination, as the case may
be, of the number of shares of Common Stock outstanding immediately prior to such reclassification into the number of shares of Common Stock outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be
“the day upon which such subdivision becomes effective” or “the day upon which such combination becomes effective”, as the case may be, and “the day upon which such subdivision or combination becomes effective” within
the meaning of paragraph (3) of this Section 12.4). 
 (8) For the purpose of any computation under paragraphs (2), (4) or
(6) (but only in the event of a tender offer under paragraph (6)) of this Section 12.4 and Section 14.1, the current market price per share of Common Stock on any date shall be calculated by the Company and be the average of the
daily Closing Prices Per Share for the five consecutive Trading Days selected by the Company commencing not more than five Trading Days before, and ending not later than the earlier of the day in question and the day before the “ex date”
with respect to the issuance or distribution requiring such computation. For the purpose of any computation under paragraph (5) of this Section 12.4, the current market price per share of Common Stock shall be the average of the daily
Closing Prices Per Share for the first five Trading Days from and including the “ex date.” For purposes of this paragraph, the term “ex date,” when used with respect to any issuance or distribution, means the first date on which
the Common Stock trades regular way in the applicable securities market or on the applicable securities exchange without the right to receive such issuance or distribution. 
 (9) All calculations under this Article XII shall be made to the nearest cent or to the nearest ten-thousandth (1/10,000th) of a share, as the case may be. Additionally, no adjustment need be made for a change in the par value of the Common
Stock. 
 (10) The Company may make such increases in the Conversion Rate, for the remaining term of the Securities or any shorter term, in
addition to those required by paragraphs (1), (2), (3), (4), (5) and (6) of this Section 12.4, as it considers to be advisable in order to avoid or diminish any income tax to any holders of shares of Common Stock resulting from any
dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from 

  

 81 

 
any event treated as such for income tax purposes. The Company shall have the power to resolve any ambiguity or correct any error in this paragraph
(10) and its actions in so doing shall, absent manifest error, be final and conclusive. 
 (11) Notwithstanding the foregoing provisions
of this Section, no adjustment of the Conversion Rate shall be required to be made upon the issuance of shares of Common Stock pursuant to any present or future plan for the reinvestment of dividends. 
 (12) To the extent permitted by applicable law and so long as such an increase is in accordance with the rules of the Nasdaq National Market or other
applicable over-the-counter trading market or national securities exchange where the Common Stock is then listed or traded, the Company from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least
twenty (20) days, the increase is irrevocable during such period, and the Board of Directors shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive; provided,
however, that no such increase shall be taken into account for purposes of determining whether the Closing Price Per Share of the Common Stock equals or exceeds 105% of the Conversion Price in connection with an event which would otherwise be a
Fundamental Change pursuant to Section 14.3. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall give notice of the increase to the Holders in the manner provided in Section 1.6 and to the
Trustee at least fifteen (15) days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 
 (13) Pursuant to rights issued under any rights plan of the Company (the “Rights Plan”), to the extent the Rights Plan is still in effect, upon
conversion of any Security by the holder thereof, such holders will receive, in addition to the Common Stock issuable upon such conversion, the rights described in the Rights Plan, whether or not the rights have separated from the underlying Common
Stock at the time of conversion, unless the distribution of such rights would cause certain tax implications as specified in the Rights Plan, in which case the holder shall not receive such rights upon conversion, and in lieu thereof, the Conversion
Rate will be adjusted effective immediately prior to conversion pursuant paragraph (4) of this Section 12.4, as though such rights had been distributed to holders of Common Stock on the day immediately preceding the conversion date.

 (14) In case of a Fundamental Change as specified in clauses (ii), (iii) or (iv) of the definition thereof, solely upon receipt
by the Conversion Agent of any Holder’s Conversion Notice on or after the Effective Date of the Fundamental Change and prior to the 45th day following such Effective Date (or, if earlier and to the extent applicable, the close of business on
the second Business Day immediately preceding the Fundamental Change Repurchase Date (as specified in the Fundamental Change Repurchase Right Notice)), the Company shall increase the Conversion Rate for the Securities surrendered for conversion by
such Holder by the number of Additional Shares determined in accordance with this Section 12.4; provided, however, that no increase shall be made in the case of a Fundamental Change if at least 90% of the consideration paid for
the Common Stock (excluding cash payments for fractional shares and cash payments made pursuant to dissenters’ appraisal rights) in such Fundamental Change transaction consists of shares of capital stock traded on New York Stock Exchange or
another United States national securities exchange or quoted on the Nasdaq National Market or another established automated 

  

 82 

 
over-the-counter trading market in the United States (or that will be so traded or quoted immediately following the transaction) and as a result of such
transaction or transactions the Securities become convertible solely into such common stock. The number of Additional Shares will be determined by reference to the table below. 
 The following table sets forth number of Additional Shares issuable per $1,000 initial principal amount of Securities as a result of a Fundamental Change
that occurs in the corresponding period:

 The Stock Prices set forth in the first row of the table above shall be adjusted as of any date on
which the Conversion Rate of the Securities is adjusted in accordance with Section 12.4 hereof. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by an adjustment factor equal to
a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares shall be
adjusted in the same manner and for the same events as the Conversion Rate as set forth in Section 12.4 hereof. 
 The exact Stock Price
and conversion dates may not be set forth on the table; in which case, if: 
 (A) the Stock Price is between two Stock Price amounts on
the table or the conversion date is between two dates on the table, the number of Additional Shares will be determined by straight-line interpolation between the number of Additional Shares set forth for the higher and lower stock price amounts and
the two dates, as applicable, based on a 365-day year; 
 (B) the Stock Price is more than $68.00 per share (subject to adjustment), no
further adjustment will be made to the Conversion Rate as a result of the Fundamental Change; and 
 (C) the Stock Price is less than
$13.50 per share (subject to adjustment), no further adjustment will be made to the Conversion Rate as a result of the Fundamental Change. 
 Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock issuable upon conversion of a Security exceed 74.0328 per $1,000 initial principal amount of the Securities, subject to proportional adjustment
in the same manner as the Conversion Rate as set forth in Section 12.4 hereof. 
  

 83 

 SECTION 12.5 Notice of Adjustments of Conversion Rate. 
 Whenever the Conversion Rate is adjusted as herein provided: 
 (1) the Company shall compute the adjusted Conversion Rate in accordance with Section 12.4 and shall prepare a certificate signed by the principal financial officer of the Company setting forth the adjusted
Conversion Rate and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall promptly be filed with the Trustee and with each Conversion Agent; and 
 (2) upon each such adjustment, a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted Conversion Rate shall be
required, and as soon as reasonably practicable after it is required, such notice shall be provided by the Company to all Holders in accordance with Section 1.6 and to the Trustee. 
 Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such certificate or the information and
calculations contained therein, except to exhibit the same to any Holder of Securities desiring inspection thereof at its office during normal business hours, and shall not be deemed to have knowledge of any adjustment in the Conversion Rate unless
and until a Responsible Officer of the Trustee shall have actually received such a certificate. Until a Responsible Officer of the Trustee so receives such a certificate, the Trustee and each Conversion Agent may assume without inquiry that the last
Conversion Rate of which the Trustee has knowledge of remains in effect. 
 SECTION 12.6 Notice of Certain Corporate Action.

 In case: 
 (1) the Company
shall declare a dividend (or any other distribution) on its Common Stock payable otherwise than exclusively in cash; or 
 (2) the Company
shall authorize the granting to all or substantially all of the holders of its Common Stock of rights, options or warrants to subscribe for or purchase any shares of capital stock of any class or of any other rights; or 
 (3) of any reclassification of the Common Stock, or of any consolidation, merger or share exchange to which the Company is a party and for which approval
of any shareholders of the Company is required, or of the conveyance, sale, transfer or lease of all or substantially all of the assets of the Company; or 
 (4) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; 
 then the Company shall cause to
be filed at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 10.2, and shall cause to be provided to all Holders in accordance with Section 1.6, at least 10 days prior to the applicable
record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, rights, options or warrants, or, if a record is not to be taken, the date 

  

 84 

 
as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights, options or warrants are to be determined or
(y) the date on which such reclassification, consolidation, merger, conveyance, transfer, sale, lease, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock
of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, conveyance, transfer, sale, lease, dissolution, liquidation or winding up.
Neither the failure to give such notice or the notice referred to in the following paragraph nor any defect therein shall affect the legality or validity of the proceedings described in clauses (1) through (4) of this Section 12.6. If
at the time the Trustee shall not be the Conversion Agent, a copy of such notice shall also forthwith be filed by the Company with the Trustee. 
 The Company shall cause to be filed at the Corporate Trust Office and each office or agency maintained for the purpose of conversion of Securities pursuant to Section 10.2, and shall cause to be provided to all Holders in accordance
with Section 1.6, notice of any purchase by the Company or any Subsidiary of all or any portion of the Common Stock at or about the time that such notice of purchase, if any, is provided to the public generally. 
 SECTION 12.7 Company to Reserve Common Stock.
 The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of Securities, the full number of
shares of Common Stock then issuable upon the conversion of all Outstanding Securities. 
 SECTION 12.8 Taxes on
Conversions.
 Except as provided in the next sentence, the Company will pay any and all taxes and duties that may be payable in respect of
the issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any tax or duty that may be payable in respect of (i) income of the Holder, or (ii) any
transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made unless and until the Person requesting such
issue has paid to the Company the amount of any such tax or duty, or has established to the satisfaction of the Company that such tax or duty has been paid. 
 SECTION 12.9 Covenant as to Common Stock.
 Before taking any action which would cause an adjustment reducing the Conversion Price below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Securities, the Company shall take
all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common Stock at such adjusted Conversion Price. 
 The Company agrees that all shares of Common Stock that may be delivered upon conversion of Securities, upon such delivery, will have been duly
authorized and validly issued and will be fully paid and nonassessable and free of any lien or adverse claim created by the 

  

 85 

 
Company and, except as provided in Section 12.8, the Company will pay all taxes, liens and charges with respect to the issue thereof. 
 The Company further covenants that as long as the Common Stock is listed on the Nasdaq National Market, the Company shall use its best efforts to cause
all Common Stock issuable upon conversion of the Securities to be listed on the Nasdaq National Market in accordance with, and at the times required under, the requirements of the Nasdaq National Market, and if at any time the Common Stock becomes
listed or admitted to trading on any other national securities exchange, or quoted on any other automated quotation system, the Company shall use its best efforts to cause all Common Stock issuable upon conversion of the Securities to be so listed
or quoted and kept so listed or quoted. 
 SECTION 12.10 Cancellation of Converted Securities.
 All Securities delivered for conversion shall be delivered to the Trustee or its agent to be canceled by or at the direction of the Trustee, which shall
dispose of the same as provided in Section 3.9. 
 SECTION 12.11 Provision in Case of Reclassification, Consolidation,
Merger or Sale of Assets.
 In case 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 subdivision or combination), (ii) any consolidation or merger of the Company with or into any other Person, any merger of another Person
with or into the Company (other than a merger that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock of the Company), or (iii) any conveyance, sale, transfer or lease of all or
substantially all of the assets of the Company (other than a sale of all or substantially all of the assets of the Company that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock of
the Company), in each case as a result of which holders of Common Stock shall be entitled to receive stock, other securities, other property, assets or cash for such holders’ Common Stock, the Person formed by such consolidation or resulting
from such merger or which acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then Outstanding shall have the right thereafter, during the period such
Security shall be convertible as specified in Section 12.1, to convert such Security only into the kind and amount of securities, cash and other property receivable upon such reclassification, change, consolidation, merger, conveyance, sale,
transfer or lease by a holder of the number of shares of Common Stock of the Company into which such Security might have been converted immediately prior to such reclassification, change, consolidation, merger, conveyance, sale, transfer or lease,
assuming such holder of Common Stock of the Company (x) is not (A) a Person with which the Company consolidated or merged with or into or which merged into or with the Company or to which such conveyance, sale, transfer or lease was made,
as the case may be (a “Constituent Person”), or (B) an Affiliate of a Constituent Person and (y) failed to exercise its rights of election, if any, as to the kind or amount of securities, cash and other property receivable upon
such reclassification, change, consolidation, merger, conveyance, sale, transfer or lease (provided that, if the kind or amount of securities, cash and other property receivable upon such reclassification, 

  

 86 

 
change, consolidation, merger, conveyance, sale, transfer, or lease is not the same for each share of Common Stock of the Company held immediately prior to
such reclassification, change, consolidation, merger, conveyance, sale, transfer or lease by others than a Constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised (“Non-electing
Share”), then for the purpose of this Section 12.11, the kind and amount of securities, cash and other property receivable upon such reclassification, change, consolidation, merger, conveyance, sale, transfer or lease by the holders of
each Non-electing Share shall be deemed to be the kind and amount elected by a majority of the Company’s shareholders in any of (i) through (iii) above). Such supplemental indenture shall provide for adjustments that, for events
subsequent to the effective date of such supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article XII. The above provisions of this Section 12.11 shall similarly apply to
successive consolidations, mergers, conveyances, sales, transfers or leases. Notice of the execution of such a supplemental indenture shall be given by the Company to the Holder of each Security as provided in Section 1.6 promptly upon such
execution. 
 Neither the Trustee nor any Conversion Agent shall be under any responsibility to determine whether a supplemental indenture
under this Article XII need be entered into or the correctness of any provisions contained in any such supplemental indenture relating either to the kind or amount of shares of stock or other securities or property or cash receivable by Holders of
Securities upon the conversion of their Securities after any such consolidation, merger, conveyance, transfer, sale or lease or to any such adjustment or as to any other provisions of any such supplemental indenture relating to this Article XII, but
may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, an Opinion of Counsel with respect thereto, which the Company shall cause to be furnished to the Trustee upon request. 

SECTION 12.12 Rights Issued in Respect of Common Stock.
 In the event of any distribution of rights or warrants by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s capital stock (either
initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): 
  

	 	(i)	are deemed to be transferred with such shares of Common Stock, 

  

	 	(ii)	are not exercisable, and 

  

	 	(iii)	are also issued in respect of future issuance of Common Stock 

 shall not
be deemed distributed for purposes of Section 12.4(2) until the occurrence of the earliest Trigger Event. In addition, in the event of any distribution of rights or warrants, or any Trigger Event with respect thereto, shall have resulted in an
adjustment to the Conversion Rate under Section 12.4(2), (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon
such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder of Common Stock with
respect to such rights or warrants (assuming 

  

 87 

 
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 any such rights or warrants all of which shall have expired without exercise by any holder thereof, the Conversion Price shall be readjusted as if such issuance had not occurred. 
 SECTION 12.13 Responsibility of Trustee for Conversion Provisions.
 The Trustee and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Securities to determine whether any facts
exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed, herein or in any supplemental indenture provided to be employed, in
making the same, or whether a supplemental indenture need be entered into or whether any provisions of any such supplemental indenture are correct. Neither the Trustee nor any Conversion Agent shall be accountable with respect to the validity or
value (or the kind or amount) of any Common Stock, or of any other securities or property or cash, which may at any time be issued or delivered upon the conversion of any Security; and it or they do not make any representation with respect thereto.
Neither the Trustee, nor any Conversion Agent shall be responsible for any failure of the Company to make or calculate any cash payment or to issue, transfer or deliver any shares of Common Stock or share certificates or other securities or property
or cash upon the surrender of any Security for the purpose of conversion; and the Trustee and any Conversion Agent shall not be responsible for any failure of the Company to comply with any provisions contained in this Article XII. 
 ARTICLE XIII 
 SUBORDINATION OF SECURITIES

 SECTION 13.1 Securities Subordinate to Senior Debt.
 Notwithstanding any other provision of this Indenture, the Company covenants and agrees, and each Holder, by its acceptance of a Security, likewise
covenants and agrees, that all Securities shall be issued subject to the provisions of this Article XIII and each Person holding any Security, whether upon original issue or upon transfer, assignment or exchange thereof, accepts and agrees that the
Securities shall, to the extent set forth in this Article XIII, be subordinated in right of payment to the prior payment in full, in cash, of all amounts that constitute Senior Debt. 
 The Securities will be on parity in the right of payment with the Company’s other existing and future liabilities that are not otherwise
subordinated in favor of the Securities. 
 The Securities will be senior in the right of payment to all other Indebtedness of the Company
that by its terms is expressly subordinate to the Securities. 
 SECTION 13.2 No Payment in Certain Circumstances, Payment
over of Proceeds upon Dissolution, Etc.
 (1) No direct or indirect payment on account of the Securities (including, but not limited to, the
Redemption Price with respect to the Securities to be called for redemption in accordance with Article XI or the Repurchase Price with respect to Securities submitted for 

  

 88 

 
repurchase in accordance with Article XIV) by or on behalf of the Company shall be made, without the consent of the holders of such Senior Debt, if, at the
time of such payment, there shall have occurred and be continuing a default in any payment in respect of the Senior Debt (including upon acceleration of the maturity thereof) when due (a “Senior Payment Default”). 
 (2) In addition, if any default (other than a Senior Payment Default) with respect to any Senior Debt permitting, or which with the giving of notice or
lapse of time (or both) would permit, the holders thereof (or an agent or a trustee on behalf thereof) to accelerate the maturity thereof (a “Senior Non-monetary Default”) has occurred and is continuing and the Company and the Trustee have
received written notice thereof from an authorized person on behalf of Senior Debt, then the Company may not make any payments on account of the Securities (including, but not limited to, the Redemption Price with respect to the Securities to be
called for redemption in accordance with Article XI or the Repurchase Price with respect to Securities submitted for repurchase in accordance with Article XIV) for a period (a “Payment Blockage Period”) commencing on the date the Company
and the Trustee receive such written notice and ending on the earlier of (i) 179 days after such date or on the date on which the Trustee receives notice from any authorized person on behalf of the Senior Debt for which the blockage notice was
given rescinding such notice and (ii) the date, if any, on which the Senior Debt to which such default relates is discharged or such default is waived or otherwise cured provided that no other default then exists except, in each case,
any acceleration of the Senior Debt. 
 (3) Not more than one Payment Blockage Period pursuant to Section 13.2(2) may be commenced with
respect to the Securities during any period of 360 consecutive days. Notwithstanding anything in this Indenture to the contrary, there must be 180 consecutive days in any 360-day period in which no Payment Blockage Period is in effect. For all
purposes of Section 13.2(2) and this Section 13.2(3), no event of default that existed or was continuing (provided that any subsequent action that would give rise to an event of default pursuant to any provision under which an event
of default previously existed or was continuing shall constitute a new event of default for this purpose; and provided that the failure to repay the Senior Debt upon acceleration shall constitute a Senior Payment Default subject to the terms
of Section 13.2(1)) on the date of the commencement of any Payment Blockage Period with respect to the Senior Debt initiating such Payment Blockage Period shall be, or shall be made, the basis for the commencement of a second Payment Blockage
Period by the representative for, or the holders of, such Senior Debt, whether or not within a period of 360 consecutive days, unless such event of default shall have been cured or waived for a period of not less than 90 consecutive days.

 (4) Upon any payment or distribution of assets or securities of the Company to creditors of any kind or character, whether in cash,
property or securities, in connection with any dissolution or winding up or total or partial liquidation or reorganization of the Company, whether voluntary or involuntary, or in a bankruptcy, insolvency, receivership or other proceedings, the
holders of Senior Debt will first be entitled to receive payment in full in cash of principal of (and premium, if any) and interest on, and all other payment obligations payable on such Senior Debt (whether or not allowed in such proceeding) before
the Holders are entitled to receive any payment on account of the Securities (including, but not limited to, the Redemption Price with respect to the Securities to be called for redemption in accordance with Article XI or the Repurchase Price with
respect to Securities submitted for repurchase in accordance with Article XIV). 
  

 89 

 (5) To the extent any payment of Senior Debt (whether by or on behalf of the Company, as proceeds of
security or enforcement of any right of setoff or otherwise) is declared to be fraudulent or preferential, set aside or required to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent or other similar Person under any
bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then if such payment is recovered by, or paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent or other similar Person, the Senior Debt or part
thereof originally intended to be satisfied shall be deemed to be reinstated and outstanding as if such payment had not occurred. To the extent the obligation to repay any Senior Debt is declared to be fraudulent, invalid or otherwise set aside
under any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then the obligations so declared fraudulent, invalid or otherwise set aside (and all other amounts that would come due with respect thereto had such obligation not
been so affected) shall be deemed to be reinstated and outstanding as Senior Debt for all purposes of this Indenture as if such declaration, invalidity or setting aside had not occurred. 
 (6) If, notwithstanding the foregoing provision prohibiting such payment or distribution, any payment or distribution of assets or securities of the
Company of any kind or character (excluding shares of the Company’s common stock or securities provided for in a plan reorganization or readjustment which are subordinate in right of payment to all Senior Debt to substantially the same extent
as, or to a greater extent than, the Securities are so subordinated), whether in cash, property or securities, shall be received by the Trustee or any Holder at a time when such payment or distribution is prohibited by Section 13.2(1) or
Section 13.2(2) and before all obligations in respect of Senior Debt are paid in full, in cash, such payment or distribution shall be received and held in trust for the benefit of, and shall be paid over or delivered to, the holders of Senior
Debt (pro rata to such holders on the basis of the respective amounts of Senior Debt held by such holders) or their representatives or to the trustee or trustees under any indenture pursuant to which any such Senior Debt may have been issued, as
their respective interests appear, for application to the payment of Senior Debt remaining unpaid until all such Senior Debt has been paid in full, in cash, after giving effect to any concurrent payment, distribution or provision therefor to or for
the holders of such Senior Debt. 
 (7) The consolidation of the Company with, or the merger of the Company with or into, another Person or
the liquidation or dissolution of the Company following the sale, conveyance, transfer, lease or other disposition of all or substantially all of its property and assets to another Person upon the terms and conditions provided in Article VII shall
not be deemed a dissolution, winding up, liquidation or reorganization for the purposes of this Section 13.2 if such other Person shall, as a part of such consolidation, merger, sale, conveyance, transfer, lease or other disposition, comply (to
the extent required) with the conditions stated in Article VII. 
 SECTION 13.3 Payment Permitted If No Default.

Nothing contained in this Article or elsewhere in this Indenture or in any of the Securities shall prevent (a) the Company, at any time except
during the pendency of any case, proceeding, dissolution, liquidation or other winding up, assignment for the benefit of creditors or other marshaling of assets and liabilities of the Company referred to in Section 13.2, or during the
circumstances referred to in the first two paragraphs of Section 13.2, from making payments at any time of principal of (and premium, if any) or interest (including Additional Interest, if any) on 

  

 90 

 
the Securities, or (b) the application by the Trustee of any money deposited with it hereunder to the payment of or on account of the principal of (and
premium, if any) or interest (including Additional Interest, if any) on the Securities or the retention of such payment by the Holders, if, at the time of such application by the Trustee, a Responsible Officer had not received actual notice that
such payment would have been prohibited by the provisions of this Article. 
 SECTION 13.4 Subrogation to Rights of Holders
of Senior Debt.
 Subject to the payment in full in cash of all Senior Debt, the Holders of the Securities shall be subrogated to the extent
of the payments or distributions made to the holders of such Senior Debt pursuant to the provisions of this Article to the rights of the holders of such Senior Debt to receive payments and distributions of cash, property and securities applicable to
the Senior Debt until the principal of (and premium, if any) and interest (including Additional Interest, if any) on the Securities shall be paid in full. For purposes of such subrogation, no payments or distributions to the holders of the Senior
Debt of any cash, property or securities to which the Holders of the Securities would be entitled except for the provisions of this Article, and no payments over pursuant to the provisions of this Article to the holders of Senior Debt by Holders of
the Securities or the Trustee, shall, as among the Company, its creditors other than holders of Senior Debt and the Holders of the Securities, be deemed to be a payment or distribution by the Company to or on account of the Senior Debt. 

SECTION 13.5 Provisions Solely to Define Relative Rights.
 The provisions of this Article are and are intended solely for the purpose of defining the relative rights of the Holders of the Securities on the one
hand and the holders of Senior Debt on the other hand. Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall (i) impair, as among the Company, its creditors other than holders of Senior
Debt and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Securities the principal of (and premium, if any) and interest (including Additional Interest, if any) on the
Securities as and when the same shall become due and payable in accordance with their terms; or (ii) affect the relative rights against the Company of the Holders of the Securities and creditors of the Company other than the holders of Senior
Debt; or (iii) prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article of the holders of Senior
Debt to receive cash, property and securities otherwise payable or deliverable to such Holder; or (iv) affect the rights of the Trustee or any Agent against the Company or prevent the Trustee or any Agent from exercising all remedies otherwise
permitted by applicable law upon breach of this Indenture. 
 SECTION 13.6 Trustee to Effectuate Subordination.

Each Holder of a Security by its acceptance thereof authorizes and directs the Trustee on its behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and appoints the Trustee its attorney-in-fact for any and all such purposes. 
  

 91 

 SECTION 13.7 No Waiver of Subordination Provisions.
 No right of any present or future holder of any Senior Debt to enforce subordination as herein provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company, or by any non-compliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise
charged with. 
 Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Debt may, at any time and from
time to time, without the consent of or notice to the Trustee or the Holders of the Securities, without incurring responsibility to the Holders of the Securities and without impairing or releasing the subordination provided in this Article or the
obligations hereunder of the Holders of the Securities to the holders of Senior Debt, do any one or more of the following, and each Holder hereby consents to: (i) any amendment, modification, supplement, renewal, restatement or extensions of
time of payment of or increase or decrease in the amount of any of the Senior Debt or to any of the agreements entered into with respect thereto or any collateral at the time granted to or held by or on behalf of any holder of Senior Debt,
(ii) the taking, exchange, surrender and releasing of collateral at any time granted to or held by or on behalf of any holder of Senior Debt or guarantees now or at any time held by or available to any holder of Senior Debt or any other person
at any time liable for or in respect of the Senior Debt, (iii) the exercise of, or refraining from the exercise of any rights against the Company or any other obligor or any collateral at any time granted to or held by or on behalf of any
holder of Senior Debt and/or (iv) the settlement, compromise or release of, or the waiver of any default with respect to, any of the Senior Debt. 
 SECTION 13.8 Notice to Trustee.
 The Company shall give prompt written notice to the Trustee of any fact
known to the Company that would prohibit the making of any payment to or by the Trustee in respect of the Securities. Notwithstanding the provisions of this Article or any other provision of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts which would prohibit the making of any payment by the Trustee in respect of the Securities, unless and until a Responsible Officer of the Trustee shall have actually received written notice thereof from the
Company or a Representative or a holder of Senior Debt and, prior to such actual receipt by a Responsible Officer of any such written notice, the Trustee, subject to the provisions of Section 6.1, shall be entitled in all respects to assume
that no such facts exist; provided, however, that if the Trustee shall not have received the notice provided for in this Section 13.8 at least five Business Days prior to the date upon which by the terms hereof any money may become
payable for any purpose (including, without limitation, the payment of the principal of (and premium, if any) or interest (including Additional Interest, if any) on any Security), then, anything herein contained to the contrary notwithstanding, the
Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money was received and shall not be affected by any notice to the contrary which may be received by it within five Business Days
prior to such date. 
  

 92 

 Notwithstanding anything in this Article XIII to the contrary, nothing shall prevent any payment by the
Trustee to the Holders of monies deposited with it pursuant to Section 4.1, and any such payment shall not be subject to the provisions of Section 13.2. 
 Subject to the provisions of Section 6.1, the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a Representative or a holder of Senior Debt to
establish that such notice has been given by a Representative or a holder of Senior Debt. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Debt to
participate in any payment or distribution pursuant to this Article, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Debt held by such Person, the extent to which such
Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article, and if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment. 
 SECTION 13.9 Reliance on Judicial Order or
Certificate of Liquidating Agent.
 Upon any payment or distribution of assets of the Company referred to in this Article, the Trustee,
subject to the provisions of Section 6.1, and the Holders of the Securities shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which such insolvency, bankruptcy, receivership, liquidation,
reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such
payment or distribution, delivered to the Trustee or to the Holders of Securities, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Debt and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article. 
 SECTION 13.10 Trustee Not Fiduciary for Holders of Senior Debt.
 With respect to the holders of Senior Debt, the Trustee undertakes to perform only such obligations on the part of the Trustee as are expressly and
specifically set forth in this Article XIII, and no implied covenants or obligations on the part of the Trustee with respect to the holders of the Senior Debt shall be implied or read into this Indenture against the Trustee. The Trustee shall not be
deemed to owe any fiduciary duty to the holders of Senior Debt and shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Company or to any other Person cash, property
or securities to which any holders of Senior Debt shall be entitled by virtue of this Article or otherwise. 
 SECTION 13.11
Reliance by Holders of Senior Debt on Subordination Provisions.
 Each Holder by accepting a Security acknowledges and agrees that the
foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each holder of any Senior Debt, whether such Senior Debt was created or acquired before or after the issuance of the Securities, to acquire and
continue to hold, or to continue to hold, such Senior Debt 

  

 93 

 
and such holder of Senior Debt shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in
continuing to hold, such Senior Debt, and no amendment or modification of the provisions contained herein shall diminish the rights of such holders of Senior Debt unless such holders shall have agreed in writing thereto. 
 SECTION 13.12 Rights of Trustee as Holder of Senior Debt; Preservation of Trustee’s Rights.
 The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article with respect to any Senior Debt which may at any time
be held by it, to the same extent as any other holder of Senior Debt, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. 
 Nothing in this Article shall apply to claims of, or payments to, the Trustee, in any of its various capacities, under or pursuant to Section 6.7. 
 SECTION 13.13 Article Applicable to Paying Agents.
 In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article shall in such case (unless the
context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article in addition to or in place of the Trustee;
provided, however, that this Section 13.13 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. 
 SECTION 13.14 Certain Conversions and Repurchases Deemed Payment.
 For the purposes of this Article only, (i) the issuance and delivery of junior securities upon conversion of Securities in accordance with Article
XII shall not be deemed to constitute a payment or distribution on account of the principal of or premium or interest (including Additional Interest, if any) on Securities or on account of the purchase or other acquisition of Securities, and
(ii) the payment, issuance or delivery of cash (except in satisfaction of fractional shares pursuant to Section 12.3), property or securities (other than junior securities) upon conversion of a Security shall be deemed to constitute
payment on account of the principal of such Security. For the purposes of this Section, the term “junior securities” means (a) shares of any stock of any class of the Company and securities into which the Securities are convertible
pursuant to Article XII and (b) securities of the Company which are subordinated in right of payment to all Senior Debt that may be outstanding at the time of issuance or delivery of such securities to substantially the same extent as, or
to a greater extent than, the Securities are so subordinated as provided in this Article. Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other
than holders of Senior Debt and the Holders of the Securities, the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article XII. 
  

 94 

 ARTICLE XIV 
 REPURCHASE OF SECURITIES AT THE OPTION OF THE HOLDER 
 SECTION 14.1 Right to Require
Repurchase Upon a Fundamental Change.
 In the event that a Fundamental Change (as hereinafter defined) shall occur, then each Holder shall
have the right, at the Holder’s option, to require the Company to repurchase, and upon the exercise of such right the Company shall repurchase, all of such Holder’s Securities not theretofore converted or called for redemption, or any
portion of the aggregate principal amount thereof that is equal to $1,000 or any integral multiple of $1,000 in excess thereof (provided that no single Security may be repurchased in part unless the portion of the aggregate principal amount
of such Security to be Outstanding after such repurchase is equal to $1,000 or integral multiples of $1,000 in excess thereof), on the date (the “Repurchase Date”) that is 30 Business Days after the date of the Company Notice (as defined
in Section 14.2) at a purchase price equal to 100% of the aggregate principal amount of the Securities to be repurchased plus interest accrued but unpaid to, but excluding, the Repurchase Date (the “Repurchase Price”), as provided
below; provided, however, that installments of interest on Securities whose Stated Maturity is on or prior to the Repurchase Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on
the relevant Record Date according to their terms and the provisions of Section 3.7. Such right to require the repurchase of the Securities shall not continue after a discharge of the Company from its obligations with respect to the Securities
in accordance with Article IV, unless a Fundamental Change shall have occurred prior to such discharge. Whenever in this Indenture (including Sections 2.2, 3.1, 5.1(1) and 5.8) there is a reference, in any context, to the principal of any
Security as of any time, such reference shall be deemed to include reference to the Repurchase Price payable in respect of such Security to the extent that such Repurchase Price is, was or would be so payable at such time, and express mention of the
Repurchase Price in any provision of this Indenture shall not be construed as excluding the Repurchase Price in those provisions of this Indenture when such express mention is not made. 
 SECTION 14.2 Notices; Method of Exercising Repurchase Right, Etc.
 (1) Unless the Company shall have theretofore called for redemption all of the Outstanding Securities, at least 20 Business Days prior to the anticipated
date on which a Fundamental Change will become effective or, if the Company does not have actual notice of a Fundamental Change on or before the 20th Business Day prior to the effective date of the Fundamental Change, as soon as the Company has
actual notice of a Fundamental Change, the Company or, at the request in a Company Order and expense of the Company on or before the 20th Business Day prior to the effective date of the Fundamental Change, the Trustee, shall give to all Holders of
Securities, in the manner provided in Section 1.6, notice (the “Fundamental Change Company Notice”) of the occurrence of the Fundamental Change and of the repurchase right set forth herein arising as a result thereof. The Company
shall also deliver a copy of such Company Notice to the Trustee. If such notice is to be given by the Trustee, the Company shall deliver, on or before the fifth Business Day prior to the effective date of the Fundamental Change, a Company Order
requesting the Trustee to give such notice and setting forth all the information to be included in such notice including the information set forth below. 
  

 95 

 Each Fundamental Change Company Notice shall state: 
 (i) if applicable, whether the Conversion Rate will be adjusted as described under Section 12.4, 
 (ii) the anticipated date on which the Fundamental Change will become effective, and 
 (iii) whether the Company expects that Holders of the Securities will have the right to require the Company to repurchase the Securities.

 (2) In addition to the Fundamental Change Company Notice, on or before the 20th Trading Day after the date on which a Fundamental Change
becomes effective (which Fundamental Change results in the Holders of Securities having the right to cause the Company to repurchase their Securities), the Company shall give to all Holders of Securities, the Trustee and Paying Agent and Conversion
Agent, in the manner provided in Section 1.5, notice (the “Company Notice”) of the occurrence of the Fundamental Change and of the repurchase right set forth herein arising as a result thereof. 
 Each Company Notice shall state: 
 (i) the events giving rise to a Fundamental Change, 
 (ii) if the Company will adjust the Conversion Rate pursuant
to a Fundamental Change that falls under clause (ii), (iii) or (iv) of the definition of a Fundamental Change, the Conversion Rate and any adjustments to the Conversion Rate, 
 (iii) the effective date of the Fundamental Change, if applicable, 
 (iv) the last date by which a Holder may exercise the repurchase right, 
 (v) the Repurchase Price, 
 (vi) the Repurchase Date, 
 (vii) the name and address of the Paying Agent and the Conversion
Agent, 
 (viii) that the Securities with respect to which the Company Notice has been given to the Holder may be converted
only if the Holder withdraws any repurchase notice previously delivered by the Holder in accordance with the terms of the Indenture, and 
 (ix) a description of the procedure that a Holder must follow to require the Company to repurchase the Securities. 
 No failure of the Company to give the foregoing notices or defect therein shall limit any Holder’s right to exercise a repurchase right or affect the validity of the proceedings for the repurchase of Securities. 
  

 96 

 If any of the foregoing provisions or other provisions of this Article XIV are inconsistent with
applicable law, such law shall govern. 
 (3) To exercise a repurchase right, a Holder shall deliver to the Paying Agent before the close of
business on the second Business Day immediately preceding the Repurchase Date (i) the Securities with respect to which the repurchase right is being exercised, and (ii) written notice of the Holder’s exercise of such right, duly
completed, to the Paying Agent. 
 The repurchase notice must state: 
 (i) if certificated, the certificate numbers of the Securities to be delivered to repurchase, 
 (ii) the portion of the principal amount of Securities to be repurchased, which must be $1,000 or an integral multiple of $1,000 in excess
thereof, and 
 (iii) that the Securities are to be repurchased by the Company as of the Repurchase Date pursuant to the
applicable provisions of the Securities and the Indenture. 
 Such written notice shall be irrevocable, except that the right of the Holder
to convert the Securities with respect to which the repurchase right is being exercised shall continue until the close of business on the Business Day immediately preceding the Repurchase Date. If the Securities are not in certificated form, the
repurchase notice must comply with appropriate DTC procedures. 
 (4) If the Holder exercises the right to have any portion of the principal
amount of the Securities repurchased, the Holder may not surrender that portion of the Securities for conversion unless the Holder withdraws the repurchase notice in accordance with this Section 14.2(4). The Holder may withdraw any repurchase
notice (in whole or in part) by a written notice of withdrawal delivered to the Paying Agent prior to 5:00 p.m. (Easter time), on the second Business Day prior to the Repurchase Date. 
 The notice of withdrawal must state: 
 (i) the principal amount of the withdrawn Securities, 
 (ii) if certificated, the certificate numbers of the
withdrawn Securities, and 
 (iii) the principal amount of the Securities, if any, that remains subject to the repurchase
notice. 
 If the Securities are not in certificated form, the notice of withdrawal must comply with appropriate DTC procedures. 

(5) In the event a repurchase right shall be exercised in accordance with the terms hereof, the Company will be required to repurchase the Securities
on a date chosen by the Company in its sole discretion that is not less than 20 and no more than 35 Business Days after the date of the Company’s mailing of the relevant Fundamental Change Company Notice, subject to 

  

 97 

 
extension to comply with applicable law. To receive payment of the Repurchase Price, the Holder must either effect book-entry transfer or deliver the
Securities, together with necessary endorsements, to the office of the Paying Agent after delivery of the repurchase notice. Holders will receive payment of the Repurchase Price promptly following the later of the Repurchase Date or the time of
book-entry transfer or the delivery of the Securities. If the Paying Agent, other than the Company or a subsidiary of the Company, holds money or securities sufficient to pay the Repurchase Price of the Securities on the Business Day following the
Repurchase Date, then: 
 (i) the Securities will cease to be outstanding, and interest, if any, will cease to accrue (whether
or not book-entry transfer of the Securities is made and whether or not the Securities are delivered to the Paying Agent), and 
 (ii) all other rights of the Holder will terminate (other than the right to receive the Repurchase Price upon delivery or transfer of the Securities). 
 The Company will: 
 (i) comply with the provisions of Rule 13e-4 and Rule 14e-1, if
applicable, 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 applicable federal and state securities laws in connection with any offer
by the Company to repurchase the Securities upon a Fundamental Change. 
 (6) If any Security (or portion thereof) surrendered for repurchase
shall not be so paid on the Repurchase Date, the aggregate principal amount of such Security (or portion thereof, as the case may be), shall, until paid, bear interest to the extent permitted by applicable law from the Repurchase Date at the rate of
4% per annum, and each Security shall remain convertible into Common Stock until the principal of such Security (or portion thereof, as the case may be) shall have been paid or duly provided for. 
 (7) Any Security that is to be repurchased only in part shall be surrendered to the Trustee (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or its attorney duly authorized in writing), and the Company shall execute, and upon its actual receipt by a
Responsible Officer of a Company Order to such effect, the Trustee shall authenticate and make available for delivery to the Holder of such Security pursuant to such Company Order without service charge, a new Security or Securities, containing
identical terms and conditions, each in an authorized denomination in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Security so surrendered. 
 (8) All Securities delivered for repurchase shall be delivered to the Trustee to be canceled at the direction of the Trustee, which shall dispose of the
same as provided in Section 3.9. 
  

 98

 U.S. BANK NATIONAL ASSOCIATION 
 555 S.W. Oak Street, PDF-OR-P6TD 
 Portland, OR 97204 
 Attention: Corporate Trust Services 
  

	 	Re:	4% CONVERTIBLE SENIOR SUBORDINATED NOTES DUE 2013 OF MERIX CORPORATION (THE “SECURITIES”) 

 Reference is made to the Indenture, dated as of May 16, 2006 (the “Indenture”), between MERIX CORPORATION (the “Company”) and
U.S. BANK NATIONAL ASSOCIATION, as Trustee. Terms used herein and defined in the Indenture or Rule 144 under the United States Securities Act of 1933, as amended (the “Securities Act”), are used herein as so defined. 
 This certificate relates to $             aggregate principal amount of Securities,
which are evidenced by the following certificate(s) (the “Specified Securities”): 
 CUSIP No.
                                        
             
 CERTIFICATE No(s).
                                 
 The person in whose name this certificate is executed below (the “Undersigned”) hereby certifies that either (i) it is the sole beneficial
owner of the Specified Securities or (ii) it is acting on behalf of all the beneficial owners of the Specified Securities and is duly authorized by them to do so. Such beneficial owner or owners are referred to herein collectively as the
“Owner”. If the Specified Securities are represented by a Global Security, they are held through the Depositary or an Agent Member in the name of the Undersigned, as or on behalf of the Owner. If the Specified Securities are not
represented by a Global Security, they are registered in the name of the Undersigned, as or on behalf of the Owner. 
 The Owner has
requested that the Specified Securities be transferred to a person (the “Transferee”) who will take delivery in the form of a Restricted Security. In connection with such transfer, the Owner hereby certifies that, unless such transfer is
being effected pursuant to an effective registration statement under the Securities Act, it is being effected in accordance with Rule 144A, to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2),
(3) or (7), or pursuant to another exemption from registration under the Securities Act (if available) or Rule 144 under the Securities Act and all applicable securities laws of the states of the United States and other jurisdictions.
Accordingly, the Owner hereby further certifies as: 
 (1) RULE 144A TRANSFERS. If the transfer is being effected in accordance with
Rule 144A: 
 (A) the Specified Securities are being transferred to a person that the Owner and any person acting on its
behalf reasonably believe is a “qualified institutional buyer” within the meaning of Rule 144A, acquiring for its own account or for the account of a qualified institutional buyer; and 

 (B) the Owner and any person acting on its behalf have taken reasonable steps to ensure
that the Transferee is aware that the Owner may be relying on Rule 144A in connection with the transfer; and 
 (2) RULE 144 TRANSFERS. If
the transfer is being effected pursuant to Rule 144: 
 (A) the transfer is occurring after a holding period of at least one
year (computed in accordance with paragraph (d) of Rule 144) has elapsed since the date the Specified Securities were acquired from the Company or from an affiliate (as such term is defined in Rule 144) of the Company, whichever is later, and
is being effected in accordance with the applicable amount, manner of sale and notice requirements of paragraphs (e), (f) and (h) of Rule 144; or 
 (B) the transfer is occurring after a period of at least two years has elapsed since the date the Specified Securities were acquired from the Company or from an affiliate (as such term is defined in Rule 144) of the
Company, whichever is later, and the Owner is not, and during the preceding three months has not been, an affiliate of the Company.

not, and during the preceding three months has not been, an affiliate of the Company. The Owner also acknowledges that any future transfers of the Specified Securities must comply with all applicable securities laws of the states of the United
