 REGISTRATION RIGHTS AGREEMENT 
  
 This Registration Rights Agreement (the “Agreement”) is dated as of August 12, 2003, by and between PTEK
HOLDINGS, INC., a Georgia corporation (the “Company”) and CIBC WORLD MARKETS CORP. (“CIBC”) and UBS SECURITIES LLC (“UBS”, and together with CIBC, the “Initial Purchasers”).

  
 This Agreement is entered into in connection with the Purchase

Company’s 5% Convertible Subordinated Notes due 2008 (the “Firm Notes”), which are convertible into Common Stock of the Company, par value $0.01 per share (the “Underlying Shares”), plus up to an additional
$10,000,000 aggregate principal amount of the same that the Initial Purchasers may subsequently elect to purchase pursuant to the terms of the Purchase Agreement (the “Additional Notes” and, together with the Firm Notes, the

	2.	 	Shelf Registration. 

  
 (a) Shelf Registration. The Company shall file with the SEC a Registration Statement for an offering to be made on a continuous basis pursuant to
Rule 415 covering (except to the extent provided in Section 2(d)) all of the Registrable Securities (the “Initial Shelf Registration”) on or prior to the Filing Date. The Initial Shelf Registration shall be on  
  

 -4- 

 Form S-3 or another appropriate form permitting registration of such Registrable Securities for resale by Holders in the
manner or manners designated by them. The Company shall not permit any securities other than the Registrable Securities to be included in the Initial Shelf Registration or any Subsequent Shelf Registration (as defined below). 
  
 The Company shall use its commercially reasonable best efforts to cause the
Initial Shelf Registration to be declared effective under the Securities Act on or prior to the Effectiveness Date and to keep such Initial Shelf Registration continuously effective under the Securities Act until the date that is two years from the
Closing Date (as it may be shortened pursuant to clause (i) or clause (ii) immediately following, the “Effectiveness Period”), or such shorter period ending when (i) all the Registrable Securities covered by the Initial Shelf
Registration have been sold in the manner set forth and as contemplated in the Initial Shelf Registration, (ii) all the Registrable Securities (x) held by Persons who are not affiliates of the Company may be resold pursuant to Rule 144(k) under the
Securities Act or (y) cease to be outstanding or (iii) a Subsequent Shelf Registration (as defined below) covering all of the Registrable Securities has been declared effective under the Securities Act. 
  
 (b) Subsequent Shelf Registrations. If the Initial Shelf Registration
or any Subsequent Shelf Registration ceases to be effective for any reason at any time during the Effectiveness Period (other than because of the sale of all of the securities registered thereunder), the Company shall use its commercially reasonable
best efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall within 45 days of such cessation of effectiveness amend the Initial Shelf Registration or any subsequent Shelf Registration, as
the case may be, in a manner to obtain the withdrawal of the order suspending the effectiveness thereof, or file an additional “shelf” Registration Statement pursuant to Rule 415 covering all of the Registrable Securities (a
“Subsequent Shelf Registration”). If a Subsequent Shelf Registration is filed, the Company shall use its commercially reasonable best efforts to cause the Subsequent Shelf Registration to be declared effective under the Securities
Act as soon as practicable after such filing and to keep such Registration Statement continuously effective for a period equal to the number of days in the Effectiveness Period less the aggregate number of days during which the Initial Shelf
Registration or any Subsequent Shelf Registration was previously continuously effective. As used herein the term “Shelf Registration” means the Initial Shelf Registration and any Subsequent Shelf Registration and the term
“Shelf Registration Statement” means any Registration Statement filed in connection with a Shelf Registration. 
  
 (c) Supplements and Amendments. The Company shall promptly supplement and amend the Shelf Registration if required by the rules, regulations, or
instructions applicable to the registration form used for such Shelf Registration, if required by the Securities Act, or if reasonably requested by the Holders of the majority in Amount of Registrable Securities covered by such Registration
Statement or by any underwriter of such Registrable Securities. 
  

 -5- 

 (d) Information from Holders. The Company shall provide a notice and questionnaire (together, the
“Notice and Questionnaire”) containing substantially the information called for by the Notice and Questionnaire attached as Annex A to the Offering Circular of the Company dated August 7, 2003 relating to the Notes, requesting such
information as the Company may reasonably require for use in connection with the Shelf Registration Statement or Prospectus or preliminary Prospectus included therein and in any application to be filed with or under state securities laws not fewer
than 30 calendar days prior to the time the Company intends in good faith to have the Shelf Registration Statement declared effective (the “Notice and Questionnaire Deadline”). No Holder shall be entitled to be named as a selling
securityholder in the Shelf Registration Statement, and no Holder shall be entitled to use the Prospectus that is part of the Shelf Registration Statement for offers and resales of Registrable Securities at any time, unless such Holder has returned
a completed and signed Notice and Questionnaire to the Company by the deadline for response set forth therein. Holders shall, however, have at least 20 calendar days from the date on which the Questionnaire is first mailed to them to return a
completed and signed Questionnaire to the Company. Each Holder as to which any Shelf Registration is being effected agrees to furnish promptly to the Company all information required to be disclosed so that the information previously furnished to
the Company by such seller is not materially misleading and does not omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were
made. 
  
 Beneficial owners of Registrable Securities who
have not returned a Notice and Questionnaire by the Notice and Questionnaire Deadline may receive another Notice and Questionnaire upon request from the Company. Upon receipt of a completed and signed Notice and Questionnaire prior to the
Effectiveness Date, the Company will include the Registrable Securities covered thereby in the Shelf Registration Statement. 
  
 In connection with all such requests for information from Holders, the Company shall notify such Holders of the requirements set forth above. No Holder
shall be entitled to Liquidated Damages pursuant to Section 3 hereof unless such Holder shall have provided all such reasonably requested information. 
  
 3. Liquidated Damages. 
  
 (a) The Company and the Initial Purchasers agree that the Holders will suffer damages if the Company fails to fulfill its obligations under Section 2
hereof and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Company agrees to pay liquidated damages on the Registrable Securities (“Liquidated Damages”) under the circumstances
and to the extent set forth below (each of which shall be given independent effect; each a “Registration Default”): 
  
 (i) if the Initial Shelf Registration is not filed on or prior to the Filing Date, then commencing on the day after the Filing Date,
Liquidated Damages shall accrue on the Registrable Securities at a rate of 0.25% per annum on the Amount of 
  

 -6- 

 Registrable Securities for the first 90 days immediately following the Filing Date, such Liquidated
Damages increasing by an additional 0.25% per annum at the beginning of each subsequent 90-day period; 
  
 (ii) if the Initial Shelf Registration is not declared effective by the SEC on or prior to the Effectiveness Date, then commencing on the
day after the Effectiveness Date, Liquidated Damages shall accrue on the Registrable Securities at a rate of 0.25% per annum on the Amount of Registrable Securities for the first 90 days immediately following the day after such Effectiveness Date,
such Liquidated Damages increasing by an additional 0.25% per annum at the beginning of each subsequent 90-day period; and 
  
 (iii) if a Shelf Registration has been declared effective and such Shelf Registration ceases to be effective at any time during the
Effectiveness Period (other than as permitted under Section 3(b)), Liquidated Damages shall accrue on the Registrable Securities at a rate of 0.25% per annum on the Amount of Registrable Securities for the first 90 days commencing on the day such
Shelf Registration ceases to be effective, such Liquidated Damages increasing by an additional 0.25% per annum at the beginning of each such subsequent 90-day period; 
  
 provided, however, that Liquidated Damages on the Registrable Securities may not accrue under more than one of the foregoing
clauses (i), (ii) or (iii) at any one time and at no time shall the aggregate amount of Liquidated Damages accruing exceed in the aggregate 0.50% per annum of the Amount of Registrable Securities; provided, further, however,
that (1) upon the filing of the Shelf Registration as required hereunder (in the case of clause (a)(i) of this Section 3), (2) upon the effectiveness of the Shelf Registration as required hereunder (in the case of clause (a)(ii) of this Section 3)
or (3) upon the effectiveness of a Shelf Registration which had ceased to remain effective (in the case of (a)(iii) of this Section 3), Liquidated Damages on the Registrable Securities as a result of such clause, shall cease to accrue. It is
understood and agreed that, notwithstanding any provision to the contrary, so long as any Registrable Security is then covered by an effective Shelf Registration Statement, no Liquidated Damages shall accrue on such Registrable Security. The parties
have agreed that actual damages for the Company’s violation of its obligations under Section 2 are difficult to determine and that the sole monetary remedy for any such violation shall be Liquidated Damages. 
  
 (b) Notwithstanding any other provisions of this Agreement to the contrary,
if (i) the Company determines, in its good faith judgment, that the disclosure of an event or development, or the filing of a required filing with the SEC would have a material adverse impact on the Company or (ii) the disclosure of an event or
development, or the filing of a required filing with the SEC is otherwise related to a material business transaction that has not yet been publicly disclosed (each of the foregoing is referred to herein as a “Suspension Period”),
the Company shall be entitled to suspend any registration referred to in Section 2, provided, however, that a Suspension Period shall not prevent the accrual of Liquidated Damages from occurring or continuing to the extent a Suspension Period
exceeds 45 days in any 90-day 
  

 -7- 

 period (which can be extended to 75 days in any 90-day period if the Company possesses non-public information, the
disclosure of which would have a material adverse impact on the Company or such material relates to undisclosed proposal or pending transaction and the Company believes reasonably that the disclosure of such information would impede its ability to
consummate the transaction) or to the extent multiple Suspension Periods exceed 90 days in the aggregate in any 12-month period. 
  
 (c) So long as any Convertible Notes remain outstanding, the Company shall notify the Trustee within three Business Days after each and every date on
which an event occurs in respect of which Liquidated Damages is required to be paid. Any amounts of Liquidated Damages due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section 3 will be payable in cash semi-annually on each interest payment date
under the Indenture (each a “Damages Payment Date”), commencing with the first such date occurring after any such Liquidated Damages commences to accrue, to Holders to whom regular interest is payable on such Damages Payment Date
with respect to Convertible Notes that are Registrable Securities and to Persons that are registered Holders 15 days prior to such Damages Payment Date with respect to Underlying Shares that are Registrable Securities. The amount of Liquidated
Damages for Registrable Securities will be determined by multiplying the applicable rate of Liquidated Damages by the Amount of Registrable Securities outstanding on the Damages Payment Date following such Registration Default in the case of the
first such payment of Liquidated Damages with respect to a Registration Default (and thereafter at the next succeeding Damages Payment Date until the cure of such Registration Default), multiplied by a fraction, the numerator of which is the number
of days such Liquidated Damages rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months and, in the case of a partial month, the actual number of days elapsed), and the denominator of which
is 360. 
  

	4.	 	Registration Procedures. 

  
 In connection with the filing of any Registration Statement pursuant to Section 2 hereof, the Company shall effect such registrations to permit the resale
of the securities covered thereby in accordance with the intended method or methods of disposition thereof, and pursuant thereto and in connection with any Registration Statement filed by the Company hereunder the Company shall: 
  
 (a) Prepare and file with the SEC prior to the Filing Date a Registration
Statement or Registration Statements as prescribed by Section 2 hereof and use its commercially reasonable best efforts to cause each such Registration Statement to become effective and remain effective as provided herein; provided,
however, that before filing any Registration Statement or Prospectus or any amendments or supplements thereto, the Company shall furnish to and afford the Holders of the Registrable Securities covered by such Registration Statement, a single
counsel to such Holders (chosen in accordance with Section 5(b)), and the managing underwriter, if any, a reasonable opportunity to review copies of all such documents proposed to be filed (in each case, where possible, at least four Business Days
prior to 
  

 -8- 

 such filing, or such date as is reasonable under the circumstances). The Company shall not file any Registration
Statement or Prospectus or any amendments or supplements thereto if the Holders of a majority in Amount of Registrable Securities covered by such Registration Statement, their counsel, or the managing underwriter, if any, shall reasonably object.

  
 (b) Prepare and file with the SEC such amendments and
post-effective amendments to each Shelf Registration as may be necessary to keep such Registration Statement continuously effective for the Effectiveness Period; cause the related Prospectus to be supplemented by any Prospectus supplement required
by applicable law, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) promulgated under the Securities Act; and use all commercially reasonable best efforts to comply with the provisions of the
Securities Act and the Exchange Act applicable to it with respect to the disposition of all securities covered by such Registration Statement as so amended or in such Prospectus as so supplemented. The Company shall be deemed not to have used its
commercially reasonable best efforts to keep a Registration Statement effective during the Effectiveness Period if it voluntarily takes any action that would result in selling Holders of the Registrable Securities covered thereby not being able to
sell such Registrable Securities during that period unless such action is required by applicable law or unless the Company complies with this Agreement, including, without limitation, the provisions of Sections 4(c)(ii), 4(c)(iii), 4(c)(iv) and 4(k)
hereof. 
  
 (c) Notify the selling Holders, a single counsel to
such Holders (chosen in accordance with Section 5(b)), and the managing underwriter, if any, promptly (but in any event within three Business Days) and, confirm such notice in writing, (i) when a Prospectus or any Prospectus supplement or
post-effective amendment has been filed, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective under the Securities Act (including in such notice a written statement that any Holder may,
upon request, obtain, at the sole expense of the Company, one conformed copy of such Registration Statement or post-effective amendment including financial statements and schedules, documents incorporated or deemed to be incorporated by reference,
and exhibits), (ii) of the issuance by the SEC of any stop order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of any preliminary Prospectus or the initiation of any proceedings for that
purpose, (iii) of the happening of any event, the existence of any condition, or any information becoming known that makes any statement made in such Registration Statement or related Prospectus or any document incorporated or deemed to be
incorporated therein by reference untrue in any material respect or that requires the making of any changes in or amendments or supplements to such Registration Statement, Prospectus or documents so that, in the case of the Registration Statement,
it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the Prospectus, it will not contain any
untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, unless such event,
condition, or information has otherwise been publicly disclosed by the Company through a press 
  

 -9- 

 release or Exchange Act filing, and (iv) of the Company’s determination that a post-effective amendment to a
Registration Statement would be appropriate. 
  
 (d) Use its
commercially reasonable best efforts to prevent the issuance of any order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of a Prospectus and, if any such order is issued, to use its
commercially reasonable best efforts to obtain the withdrawal of any such order at the earliest possible moment. 
  
 (e) If requested by the managing underwriter or underwriters, if any, or the Holders of the majority in Amount of Registrable Securities being sold in
connection with an underwritten offering, (i) promptly incorporate in a Prospectus supplement or post-effective amendment such information as the managing underwriter or underwriters, if any, such Holders, or counsel for any of them reasonably
determine is necessary to be included therein, (ii) make all required filings of such Prospectus supplement of such post-effective amendment as soon as reasonably practicable after the Company has received notification of the matters to be
incorporated in such Prospectus supplement or post-effective amendment, and (iii) supplement or make amendment to such Registration Statement. 
  
 (f) Furnish to each selling Holder, a single counsel to such Holders (chosen in accordance with Section 5(b)), and each managing underwriter, if any, at
the sole expense of the Company, one conformed copy of the Registration Statement or post-effective amendment thereto, including financial statements but excluding schedules, and if requested in writing, all documents incorporated or deemed to be
incorporated therein by reference, and all exhibits. 
  
 (g)
Deliver to each selling Holder, a single counsel to such Holders (chosen in accordance with Section 5(b)), and the underwriters, if any, at the sole expense of the Company, as many copies of the Prospectus (including each form of preliminary
prospectus) and each amendment or supplement thereto and any documents incorporated by reference therein as such Persons may reasonably request; and, subject to the last paragraph of Section 4 hereof, the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling Holders and the underwriters or agents, if any, and dealers (if any), in connection with the offering and sale of the Registrable Securities covered by such Prospectus and
any amendment or supplement thereto. 
  
 (h) Prior to any public
offering of Registrable Securities, to use its commercially reasonable best efforts to register or qualify, to the extent required by applicable law, and to cooperate with the selling Holders, the managing underwriter or underwriters, if any, and
their respective counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities or offer and sale under the securities or Blue Sky laws of such jurisdictions within
the United States as any selling Holder, or the managing underwriter or underwriters, if any, reasonably request; provided, however, that where Registrable Securities are offered other than through an 

  

 -10- 

 
underwritten offering, the Company agrees to cause the Company’s counsel to perform Blue Sky investigations and file registrations and qualifications
required to be filed pursuant to this Section 4(h); keep each such registration or qualification (or exemption therefrom) effective during the period such Registration Statement is required to be kept effective and do any and all other acts or
things reasonably necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by the applicable Registration Statement; provided, however, that the Company shall not be required to (A)
qualify generally to do business in any jurisdiction where it is not then so qualified, (B) take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject, or (C) subject itself to
taxation in excess of a nominal dollar amount in any such jurisdiction where it is not then so subject. 
  
 (i) Cooperate with the selling Holders and the managing underwriter or underwriters, if any, to facilitate the timely preparation and delivery of
certificates representing shares of Registrable Securities to be sold, which certificates shall not bear any restrictive legends and shall be in a form eligible for deposit with The Depository Trust Company; and enable such shares of Registrable
Securities to be in such denominations and registered in such names as the managing underwriter or underwriters, if any, or Holders may reasonably request. 
  
 (j) Use its commercially reasonable best efforts to cause the Registrable Securities covered by any Shelf Registration Statement to be registered with or
approved by such other governmental agencies or authorities as may be reasonably necessary to enable the seller or sellers thereof or the underwriter or underwriters, if any, to consummate the disposition of such Registrable Securities, except as
may be required solely as a consequence of the nature of such selling Holder’s business, in which case the Company will cooperate in all reasonable respects with the filing of such Registration Statement and the granting of such approvals.

  
 (k) Upon the occurrence of any event contemplated by paragraph
4(c)(ii), 4(c)(iii) or 4(c)(iv) hereof, as promptly as practicable prepare and (subject to Section 4(a) hereof) file with the SEC, at the sole expense of the Company, a supplement or post-effective amendment to the Registration Statement or a
supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, or file any other required document so that, as thereafter delivered to the purchasers of the Registrable Securities being sold
thereunder, any such Prospectus will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they
were made, not misleading. 
  
 (l) Prior to the effective date of
the first Registration Statement relating to the Registrable Securities, provide the Trustee with certificates for the Registrable Securities in a form eligible for deposit with The Depository Trust Company and (ii) provide required CUSIP numbers
for the Registrable Securities. 
  

 -11- 

 (m) In connection with any underwritten offering of Registrable Securities pursuant to a Shelf
Registration, enter into an underwriting agreement as is customary in underwritten offerings of securities similar to the Registrable Securities and take all such other actions as are reasonably requested by the managing underwriter or underwriters
in order to expedite or facilitate the registration or the disposition of such Registrable Securities and, in such connection, (i) make such representations and warranties to, and covenants with, the underwriters with respect to the business of the
Company and its subsidiaries (including any acquired business, property, or entity, if applicable) and the Registration Statement, Prospectus, and documents, if any, incorporated or deemed to be incorporated by reference therein, in each case, as
are customarily made by issuers to underwriters in underwritten offerings of securities similar to the Registrable Securities and confirm the same in writing if and when requested; (ii) obtain the written opinion of counsel to the Company and
written updates thereof in form, scope, and substance reasonably satisfactory to the managing underwriter or underwriters, addressed to the underwriters, and covering the matters customarily covered in opinions requested in underwritten offerings of
securities similar to the Registrable Securities and such other matters as may be reasonably requested by the managing underwriter or underwriters; and (iii) obtain “cold comfort” letters and updates thereof in form, scope, and substance
reasonably satisfactory to the managing underwriter or underwriters from the independent certified public accountants of the Company (and, if necessary, any other independent certified public accountants of any subsidiary of the Company or of any
business acquired by the Company for which financial statements and financial data are, or are required to be, included or incorporated by reference in the Registration Statement), addressed to each of the underwriters, such letters to be in
customary form and covering matters of the type customarily covered in “cold comfort” letters in connection with underwritten offerings of securities similar to the Registrable Securities and such other matters as reasonably requested by
the managing underwriter or underwriters as permitted by the Statement on Auditing Standards No. 72. The above shall be done as and to the extent required by such underwriting agreement. 
  
 (n) Make available for inspection by any selling Holder, any underwriter participating in any such disposition of
Registrable Securities, if any, and any attorney, accountant, or other agent retained by any such selling Holder or underwriter (collectively, the “Inspectors”), at the offices where normally kept, during reasonable business hours
at such time or times as shall be mutually convenient for the Company and the Inspectors as a group, all relevant financial and other records, pertinent corporate documents, and instruments of the Company and its subsidiaries (collectively, the
“Records”) as shall be reasonably necessary to enable them to exercise any applicable due diligence responsibilities, and cause the officers, directors, and employees of the Company and its subsidiaries to supply all information
reasonably requested by any such Inspector in connection with such Registration Statement. Records that the Company determines, in good faith, to be confidential and any Records that it notifies the Inspectors are confidential shall not be disclosed
by any Inspector unless (i) the disclosure of such Records is necessary to avoid or correct a material misstatement or material omission in such Registration Statement, (ii) the release of such Records is ordered pursuant to a subpoena or other
order from a court of competent jurisdiction, (iii) disclosure of such information is, in the opinion of counsel for any Inspector, necessary or advisable in 

  

 -12- 

 
connection with any action, claim, suit, or proceeding directly involving or potentially involving such Inspector and arising out of, based upon, relating
to, or involving this Agreement or any transactions contemplated hereby or arising hereunder, (iv) the information in such Records has been made generally available to the public other than through the acts of such Inspector; provided,
however, that prior notice shall be provided as soon as practicable to the Company of the potential disclosure of any information by such Inspector pursuant to clause (ii) or (iii) of this sentence to permit the Company to obtain a protective
order (or waive the provisions of this paragraph (n)) and that such Inspector shall take such actions as are reasonably necessary to protect the confidentiality of such information (if practicable) to the extent such action is otherwise not
inconsistent with, an impairment of, or in derogation of the rights and interests of any Holder or Inspector, or (v) the information in such Records has been made generally available to the public other than as a result of a breach of this
Agreement. 
  
 (o) Provide (i) the Holders to be included in such
Registration Statement and not more than one counsel for all such Holders, (ii) the underwriters, if any, thereof, (iii) the sales or placement agent, if any, thereof, and (iv) one counsel for such underwriters or agents, reasonable opportunity to
participate in the preparation of such Registration Statement, each prospectus included therein or filed with the SEC, and each amendment or supplement thereto. 
  

(p) Comply with all applicable rules and regulations of the SEC and make generally available to its securityholders earning statements satisfying the
provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) no later than 45 days after the end of any 12-month period (or 90 days after the end of any 12-month period if such
period is a fiscal year) (i) commencing at the end of any fiscal quarter in which Registrable Securities are sold to underwriters in a firm commitment or best efforts underwritten offering and (ii) if not sold to underwriters in such an offering,
commencing on the first day of the first fiscal quarter of the Company after the effective date of a Registration Statement, which statements shall cover said 12-month periods. 
  
 (q) Cooperate with each seller of Registrable Securities covered by any Registration Statement and each underwriter, if any,
participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with the National Association of Securities Dealers, Inc. (the “NASD”), including, if
the Conduct Rules of the NASD or any successor thereto as amended from time to time so require, engaging a “qualified independent underwriter” (“QIU”) as contemplated therein and making Records available to such QIU as
though it were a participating underwriter for the purposes of Section 4(n) and otherwise applying the provisions of this Agreement to such QIU (including indemnification) as though it were a participating underwriter. 
  
 (r) Cause the Indenture to be qualified under the TIA not later than the
effective date of the first Registration Statement relating to the Registrable Securities; and in connection therewith, cooperate with the Trustee and the Holders to effect such changes to the Indenture as may be required for the Indenture to be so
qualified in accordance with the terms 
  

 -13- 

 of the TIA; and execute, and use its commercially reasonable best efforts to cause the Trustee to execute, all documents
as may be required to effect such changes and all other forms and documents required to be filed with the SEC to enable the Indenture to be so qualified in a timely manner. In the event that any amendment or modification referred to in this Section
4(r) involves the appointment of a new Trustee under the Indenture, the Company shall appoint a new Trustee thereunder pursuant to the applicable provisions of the Indenture. 
  
 (s) Use its commercially reasonable best efforts to take all other steps necessary or advisable to effect the registration
of the Registrable Securities covered by a Registration Statement contemplated hereby. 
  
 Each Holder of Registrable Securities agrees by acquisition of such Registrable Securities that, upon actual receipt of any notice from the Company of the happening of any event of the kind described in Section
4(c)(ii), 4(c)(iii) or 4(c)(iv) hereof or of a suspension pursuant to Section 3(b) hereof, such Holder will forthwith discontinue disposition of such Registrable Securities covered by such Registration Statement or Prospectus until such
Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 4(k) hereof, or until it is advised in writing by the Company that the use of the applicable Prospectus may be resumed, and has received copies of
any amendments or supplements thereto. 
  

	5.	 	Registration Expenses. 

  
 (a) All fees and expenses incident to the performance of or compliance with this Agreement by the Company shall be borne by the Company, including,
without limitation, (i) all registration and filing fees (including, without limitation, (A) fees with respect to filings required to be made with the NASD in connection with an underwritten offering and (B) fees and expenses of compliance with
state securities or Blue Sky laws (including, without limitation, reasonable fees and disbursements of counsel in connection with Blue Sky qualifications of the Registrable Securities and determination of the eligibility of the Registrable
Securities for investment under the laws of such jurisdictions as provided in Section 4(h) hereof)), (ii) printing expenses, including, without limitation, expenses of printing certificates for Registrable Securities in a form eligible for deposit
with Depository and of printing prospectuses if the printing of prospectuses is requested by the managing underwriter or underwriters, if any, or by the Holders of the majority in Amount of Registrable Securities included in any Registration
Statement but excluding expenses incurred as a result of a material misstatement provided by a Holder requiring reprinting of the prospectus, (iii) messenger, telephone, and delivery expenses incurred by the Company, (iv) fees and disbursements of
counsel for the Company and reasonable fees and disbursements of a single counsel (chosen in accordance with Section 5(b)) for the sellers of Registrable Securities (subject to the provisions of Section 5(b) hereof), (v) fees and disbursements of
all independent certified public accountants referred to in Section 4(m)(iii) hereof (including, without limitation, the expenses of any special audit and “cold comfort” letters required by or incident to such performance), (vi) Securities
Act liability insurance, if the Company desires such insurance, (vii) fees and 
  

 -14- 

 expenses of all other Persons retained by the Company, (viii) internal expenses of the Company (including, without
limitation, all salaries and expenses of officers and employees of the Company performing legal or accounting duties), (ix) the expense of any annual audit, (x) the fees and expenses incurred in connection with the listing of the securities to be
registered on any securities exchange, if applicable, and (xi) the expenses relating to printing, word processing, and distributing all Registration Statements, underwriting agreements, securities sales agreements, and any other documents necessary
in order to comply with this Agreement. Notwithstanding anything in this Agreement to the contrary, each Holder shall pay all underwriting discounts and brokerage commissions with respect to any Registrable Securities sold by it. 
  
 (b) The Company shall reimburse the Holders of the Registrable Securities
being registered in a Shelf Registration for the reasonable fees and disbursements of not more than one counsel chosen by the Holders of a majority in Amount of Registrable Securities to be included in such Registration Statement. 
  

	6.	 	Indemnification and Contribution. 

  
 The Company agrees to indemnify and hold harmless (i) each Initial Purchasers and its affiliates, (ii) each Holder and its affiliates, (iii) each Person,
if any, who controls (within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act) any of the foregoing (any of the Persons referred to in this clause (iv) being hereinafter referred to as a “controlling
person”), and (v) the respective officers, directors, partners, employees, representatives, and agents of the Initial Purchasers, the Holders (including predecessor Holders) or any controlling person (any person referred to in clause (i), (ii),
(iii), or (iv) may hereinafter be referred to as an “Indemnified Holder”), from and against any and all losses, claims, damages, liabilities, and judgments (including, without limitation, reasonable legal fees and other expenses
incurred in connection with any suit, action, or proceeding or any claim asserted) caused by any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus, or any amendment or supplement
thereto or any related preliminary Prospectus, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they
were made, not misleading, except insofar as such losses, claims, damages, or liabilities are caused by any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to any
Holder furnished to the Company in writing by such selling Holder expressly for use therein; provided that, with respect to any such untrue statement in or omission from any preliminary Prospectus, this indemnity will not apply in the event
that (a) a copy of the related Prospectus (excluding any documents incorporated by reference therein) was not sent or given by such Initial Purchasers or selling Holder and (b) the untrue statement in or omission from such preliminary Prospectus was
corrected in the related Prospectus, unless, in either case, such failure to deliver the Prospectus was a result of noncompliance by the Company with the provisions of Section 4 hereof. In connection with any underwritten offering, the Company will
also indemnify the underwriters, if any, selling brokers, 
  

 -15- 

 dealers, and similar securities industry professionals participating in the distribution, their respective affiliates,
and each Person who controls such Persons (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above with respect to the indemnification of the Holders, if requested in connection with any Registration
Statement. 
  
 Each Holder agrees, severally and not jointly, to
indemnify and hold harmless the Company, its directors, officers, affiliates, and each Person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to each Holder, but only with reference to such losses, claims, damages, or liabilities which are caused by any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in
conformity with information relating to a Holder furnished to the Company in writing by such Holder expressly for use in any Registration Statement or Prospectus, or any amendment or supplement thereto or any related preliminary prospectus.

  
 If any suit, action, proceeding (including any governmental or
regulatory investigation), claim, or demand shall be brought or asserted against any Person in respect of which indemnity may be sought pursuant to either of the two preceding paragraphs, such Person (the “Indemnified Person”) shall
promptly notify the Person or Persons against whom such indemnity may be sought (each an “Indemnifying Person”) in writing, and the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified
Person otherwise than under this Section 6 and such Indemnifying Person, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others that the
Indemnifying Person may reasonably designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding; provided, however, that the failure to so notify the Indemnifying Party shall not relieve it of any
obligation or liability which it may have hereunder or otherwise. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified
Person unless (i) such Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary, (ii) such Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to such Indemnified Person,
or (iii) the named parties in any such proceeding (including any impleaded parties) include an Indemnifying Person and an Indemnified Person and the Indemnified Person shall have reasonably concluded that there may be one or more legal defenses
available to it that are different from or in addition to those available to any such Indemnifying Person. It is understood that an Indemnifying Person shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be
liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for the Indemnified
Holders shall be designated in writing by the Holders of the majority in Amount of Registrable Securities, and any such separate firm for the Company, its directors, respective officers, and such control Persons of the Company shall be designated in
writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled 
  

 -16- 

 with such consent or if there be a final judgment for the plaintiff, such Indemnifying Person agrees to indemnify any
Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested an Indemnifying Person to reimburse the Indemnified
Person for reasonable fees and expenses actually incurred by counsel as contemplated by the third sentence of this paragraph, the Indemnifying Person agrees that it shall be liable for any settlement of any proceeding effected without its consent if
(i) such settlement is entered into more than 30 days after receipt by such Indemnifying Person of the aforesaid request and (ii) such Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the
date of such settlement; provided, however, that the Indemnifying Person shall not be liable for any settlement effected without its consent pursuant to this sentence if the Indemnifying Person is contesting, in good faith, the request
for reimbursement. No Indemnifying Person shall, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or reasonably could have been a
party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement (i) includes an unconditional release of such Indemnified Person, in form and substance satisfactory to such Indemnified Person, from all
liability on claims that are the subject matter of such proceeding and (ii) does not include a statement as to or an admission of fault, culpability, or a failure to act by or on behalf of any Indemnified Person. 
  
 If the indemnification provided for in the first and second paragraphs of
this Section 6 is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages, or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person
thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages, or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifying
Person on the one hand, and the Indemnified Person on the other hand, pursuant to the Purchase Agreement or from the offering of the Registrable Securities pursuant to any Shelf Registration or (ii) if the allocation provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Indemnifying Person on the one hand, and the Indemnified Person on the
other, in connection with the statements or omissions that resulted in such losses, claims, damages, or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand, and any
Indemnified Holder on the other, shall be deemed to be in the same proportion as the total net proceeds from the initial offering and sale of Convertible Notes before deducting expenses received by the Company bear to the total net proceeds received
by such Indemnified Holder from sales of Registrable Securities giving rise to such obligations. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or such Indemnified Holder and the parties’ relative intent, knowledge, access to information, and opportunity to 
  

 -17- 

 correct or prevent such statement or omission and any other equitable considerations appropriate under the circumstances.

  
 Each of the Company and the Initial Purchasers agrees that it
would not be just and equitable if contribution pursuant to this Section 6 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately
preceding paragraph. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages, and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6, in no event shall any Holder be required to contribute
any amount in excess of the amount by which the net proceeds received by such Holder from the sale of the Registrable Securities pursuant to a Shelf Registration Statement exceeds the amount of damages which such Holder would have otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation. 
  
 The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any indemnified party at law or in equity. 
  
 The indemnity and contribution agreements contained in this Section 6 shall
remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Holder or any Person controlling any Holder or by or on behalf of the Company, its officers or
directors, or any other Person controlling the Company, and (iii) acceptance of and payment for any of the Registrable Securities. 
  

	7.	 	Rules 144 and 144A. 

  
 The Company covenants that it will file the reports required to be filed by it under the Exchange Act and the rules and regulations adopted by the SEC
thereunder in a timely manner in accordance with the requirements of the Exchange Act and, for so long as any Registrable Securities remain outstanding, if at any time the Company is not required to file such reports, it will, upon the request of
any Holder or beneficial owner of Registrable Securities, make available such information as is necessary to permit sales pursuant to Rule 144A under the Securities Act. The Company further covenants that, for so long as any Registrable Securities
remain outstanding, it will use its commercially reasonable best efforts to take such further action as any Holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable such holder to sell
Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (a) Rule 144(k) and Rule 144A under the Securities Act, as such rules may be amended from 
  

 -18- 

 time to time, or (b) any similar rule or regulation hereafter adopted by the SEC. Notwithstanding the foregoing, nothing
in this Section 7 shall be deemed to require the Company to register any of its securities pursuant to the Exchange Act. 
  

	8.	 	Underwritten Registrations. 

  
 If any of the Registrable Securities covered by any Shelf Registration are to be sold in an underwritten offering, the investment banker or investment
bankers and manager or managers that will manage the offering will be selected by the Holders of the majority in Amount of Registrable Securities to be included in such offering and will be reasonably acceptable to the Company. 
  
 No Holder of Registrable Securities may participate in any underwritten
registration hereunder unless such Holder (a) agrees to sell such Holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes
and executes all questionnaires, powers of attorney, indemnities, underwriting agreements, and other documents reasonably required under the terms of such underwriting arrangements. 
  

	9.	 	Miscellaneous. 

  
 (a) No Inconsistent Agreements. The Company has not, as of the date hereof, and the Company shall not, after the date of this Agreement, enter into
any agreement with respect to any of its securities that is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof. 
  
 The Company has not entered and will not enter into any agreement with
respect to any of its securities that will grant to any Person piggyback registration rights with respect to a Registration Statement, except to the extent any existing right has heretofore been waived. 
  
 (b) Adjustments Affecting Registrable Securities. The Company shall
not, directly or indirectly, take any action with respect to the Registrable Securities as a class that would adversely affect the ability of the Holders of Registrable Securities to include such Registrable Securities in a registration undertaken
pursuant to this Agreement. 
  
 (c) Amendments and Waivers.
The provisions of this Agreement may not be amended, modified, or supplemented, and waivers or consents to departures from the provisions hereof may not be given, otherwise than with the prior written consent of the Company and the Holders of not
less than the majority in Amount of Registrable Securities; provided, however, that Section 6 and this Section 9(c) may not be amended, modified, or supplemented without the prior written consent of the Company and each Holder (including, in the
case of an amendment, modification, or supplement of Section 6, any Person who was a Holder of Registrable Securities disposed of pursuant to any Registration Statement). Notwithstanding the foregoing, a waiver or consent to depart from the
provisions hereof with  
  

 -19- 

 respect to a matter that relates exclusively to the rights of Holders of Registrable Securities whose securities are
being sold pursuant to a Registration Statement and that does not directly or indirectly affect, impair, limit, or compromise the rights of other Holders of Registrable Securities may be given by Holders of at least a majority in Amount of the
Registrable Securities being sold by such Holders pursuant to such Registration Statement.

2003 (as amended from time to time by the parties thereto) by and between the Company and the Initial Purchasers is exercised in full) (except pursuant to Sections 2.5, 2.6, 3.3, 15.2 and 16.2) upon the execution of this Indenture, or from time to
time thereafter, may be executed by the Company and delivered to the Trustee for authentication, and the Trustee shall thereupon authenticate and deliver said Notes upon the written order of the Company, signed by the Company’s President,
Executive or Senior Vice President or any Vice President (whether or not designated by a number or numbers or word or words added before or after the title “Vice President” but excluding any Assistant Vice President). 
  
 Section 2.2 Form of Notes. The Notes and the Trustee’s
certificate of authentication to be borne by such Notes shall be substantially in the form set forth in Exhibit A, which is incorporated in and made a part of this Indenture. 
  
 Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends and
endorsements as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or as may be required to comply with any law or with any
rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or to conform to usage. 
  
 Any Note in global form shall represent such of the outstanding Notes as
shall be specified therein and shall provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be
increased or reduced to reflect transfers or exchanges permitted hereby. Any endorsement of a Note in global form to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee
or the Custodian, at the direction of the Trustee, in such manner and upon instructions given by the holder of such Notes in accordance with this Indenture. Payment of principal of and interest and premium, if any (including any redemption price),
on any Note in global form shall be made to the holder of such Note. 
  
 The terms and provisions contained in the form of Note attached as Exhibit A hereto shall constitute, and are hereby expressly made, a part of this Indenture and to the extent applicable, the Company and the Trustee, by their execution and
delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. 
  
 Section 2.3 Date and Denomination of Notes; Payments of Interest. The Notes shall be issuable in registered form without coupons in denominations
of $1,000 principal amount and integral multiples thereof. Every Note shall be dated the date of its authentication, shall bear interest from the applicable date and accrued interest shall be payable semiannually on each February 15 and August 15,
commencing February 15, 2004 as specified on the face of the form of Note, attached as Exhibit A hereto. 
  
 The person in whose name any Note (or its Predecessor Note) is registered at the close of business on any record date with respect to any interest payment
date (including any Note that is converted after the record date and on or before the interest payment date) shall be entitled to receive the interest payable on such interest payment date notwithstanding the cancellation of such Note upon any
transfer, exchange or conversion subsequent to the record date and on or prior to such interest payment date. Interest may, at the option of the Company, be paid by check mailed to the address of such person on the registry kept for such purposes;
or at the request of such holder in writing to the Company, interest on such holder’s Notes shall be paid by wire transfer in immediately available funds in accordance with the wire transfer instruction supplied by such holder from time to time

 -8- 

 different from Trustee) at least ten Business Days prior to the interest payment date. The term “record date”
with respect to any interest payment date shall mean the February 1 or August 1 preceding said February 15 or August 15. 
  
 Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months compounded semi-annually. The Company will not be
required to make any payment on the Notes due on any day which is not a Business Day until the next succeeding Business Day. The payment made on the next succeeding Business Day will be treated as though it were paid on the original due date and no
interest will accrue on the payment for the additional period of time. 
  
 Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any said February 15 or August 15 (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Noteholder on the
relevant record date by virtue of his having been such Noteholder; and such Defaulted Interest shall be paid by the Company, at its election in each case, as provided in clause (1) or (2) below: 
  
 (1) The Company may elect to make payment of any Defaulted
Interest to the persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest to be paid on each Note and the date of the payment (which shall be not less than twenty-five (25) days after the receipt by the Trustee of such notice, unless the
Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to
the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a
special record date for the payment of such Defaulted Interest which shall be not more than fifteen (15) days and not less than ten (10) days prior to the date of the proposed payment and not less than ten (10) days after the receipt by the Trustee
of the notice of the proposed payment. The Trustee shall promptly notify the Company of such special record date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the
special record date therefor to be mailed, first-class postage prepaid, to each Noteholder as of such special record date at his address as it appears in the Note register, not less than ten (10) days prior to such special record date. Notice of the
proposed payment of such Defaulted Interest and the special record date therefor having been so mailed, such Defaulted Interest shall be paid to the persons in whose names the Notes (or their respective Predecessor Notes) were 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 Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after written notice given by the Company to
the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
  
 Section 2.4 Execution of Notes. The Notes shall be signed in the name and on behalf of the Company by the facsimile signature of its President, its
Chief Executive Officer any of its Executive or Senior Vice Presidents, or any of its Vice Presidents (whether or not designated by a number or numbers 
  

 -9- 

 or word or words added before or after the title “Vice President” but excluding any Assistant Vice President)
and attested by the facsimile signature of its Secretary or any of its Assistant Secretaries (which may be printed, engraved or otherwise reproduced thereon, by facsimile or otherwise). Only such Notes as shall bear thereon a certificate of
authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, manually executed by the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 17.11), shall be entitled to the
benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly
authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture. 
  
 In case any officer of the Company who shall have signed any of the Notes shall cease to be such officer before the Notes so signed shall have been
authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such officer of the Company; and any
Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the proper officers of the Company, although at the date of the execution of this Indenture any such person was not such an
officer. 
  
 Section 2.5 Exchange and Registration of Transfer
of Notes; Restrictions on Transfer; Depositary. 
  
 (a) The
Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office and in any other office or agency of the Company designated pursuant to Section 5.2 being herein sometimes collectively referred to as
the “Note register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form capable of
being converted into written form within a reasonable period of time. The Trustee is hereby appointed “Note registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or more
co-registrars in accordance with Section 5.2. 
  
 Upon surrender
for registration of transfer of any Note to the Note registrar or any co-registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.5, the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture. 
  
 Notes may be exchanged for other Notes of any authorized denominations and of
a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes
which the Noteholder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding. 
  
 All Notes presented or surrendered for registration of transfer or for exchange shall (if so required by the Company, the Trustee, the Note registrar or
any co-registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and duly executed, by the Noteholder thereof or his attorney-in-fact duly authorized in writing. 

 
 No service charge shall be charged to the Noteholder for any exchange or
registration of transfer of Notes, but the Company may require payment of a sum sufficient to cover any tax, assessments or other governmental charges that may be imposed in connection therewith. 
  

 -10- 

 None of the Company, the Trustee, the Note registrar or any co-registrar shall be required to exchange or
register a transfer of (a) any Notes for a period of fifteen (15) days next preceding any selection of Notes to be redeemed or (b) any Notes called for redemption or, if a portion of any Note is selected or called for redemption, such portion
thereof selected or called for redemption or (c) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion. 
  
 All Notes issued upon any transfer or exchange of Notes in accordance with
this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange. 
  
 (b) So long as the Notes are eligible for book-entry settlement with the
Depositary, unless otherwise required by law, all Notes to be traded on the PORTAL Market or to a person who is not a U.S. Person (as defined in Regulation S) who is acquiring the Note in an offshore transaction (a “Non-U.S. Person”) in
accordance with Regulation S shall be represented by a Note in global form registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in such Note in global form, which does not
involve the issuance of a definitive Note, shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the
Depositary therefor. 
  
 At any time at the request of the
beneficial holder of an interest in a Note in global form, such beneficial holder shall be entitled to obtain a definitive Note upon written request to the Trustee and the Custodian in accordance with the standing instructions and procedures
existing between the Depositary and the Custodian for the issuance thereof. Upon receipt of any such request, the Trustee or the Custodian, at the direction of the Trustee, will cause, in accordance with the standing instructions and procedures
existing between the Depositary and the Custodian, the aggregate principal amount of the Note in global form to be reduced by the principal amount of the definitive Note issued upon such request to such beneficial holder and, following such
reduction, the Company will execute and the Trustee will authenticate and deliver to such beneficial holder (or its nominee) a definitive Note or Notes in the appropriate aggregate principal amount in the name of such beneficial holder (or its
nominee) and bearing such restrictive legends as may be required by this Indenture. 
  
 Any transfer of a beneficial interest in a Note in global form which cannot be effected through book-entry settlement must be effected by the delivery to the transferee (or its nominee) of a definitive Note or Notes
registered in the name of the transferee (or its nominee) on the books maintained by the Trustee in accordance with the transfer restrictions set forth herein. With respect to any such transfer, the Trustee or the Custodian, at the direction of the
Trustee, will cause, in accordance with the standing instructions and procedures existing between the Depositary and the Custodian, the aggregate principal amount of the Note in global form to be reduced by the principal amount of the beneficial
interest in the Note in global form being transferred and, following such reduction, the Company will execute and the Trustee will authenticate and deliver to the transferee (or such transferee’s nominee, as the case may be), a Note or Notes in
the appropriate aggregate principal amount in the name of such transferee (or its nominee) and bearing such restrictive legends as may be required by this Indenture. 
  
 (c) So long as the Notes are eligible for book-entry settlement, unless otherwise required by law, upon any transfer of a
definitive Note to a QIB in accordance with Rule 144A or a Non-U.S. Person in accordance with Regulation S, unless otherwise requested by the transferor, and upon receipt of the definitive Note or Notes being so transferred, together with a
certification from the transferor that the transferee is a QIB or a Non-U.S. Person (or other evidence satisfactory to the Trustee), the Trustee shall make or direct the Custodian to make, an endorsement on the Note in global form to reflect an
increase in 
  

 -11- 

 the aggregate principal amount of the Notes represented by the Note in global form by the principal amount of the Note
being transferred to the QIB or the Non-U.S. Person, the Trustee shall cancel such definitive Note or Notes and cause, or direct the Custodian to cause, in accordance with the standing instructions and procedures existing between the Depositary and
the Custodian, the aggregate principal amount of Notes represented by the Note in global form to be increased accordingly; provided that no definitive Note, or portion thereof, in respect of which the Company or an Affiliate of the Company
held any beneficial interest shall be included in such Note in global form until such definitive Note is freely tradable in accordance with Rule 144(k); provided further that the Trustee shall issue Notes in definitive form upon any
transfer of a beneficial interest in the Note in global form to the Company or any Affiliate of the Company. 
  
 Any Note in global form may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the
provisions of this Indenture as may be required by the Custodian, the Depositary or by the National Association of Securities Dealers, Inc. in order for the Notes to be tradeable on the PORTAL Market or as may be required for the Notes to be
tradeable on any other market developed for trading of securities pursuant to Rule 144A or required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated quotation
system upon which the Notes may be listed or traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Notes are subject. 
  
 (d) Every Note that bears or is required under this Section 2.5(d) to bear
the legend set forth in this Section 2.5(d) (together with any Common Stock issued upon conversion of the Notes and required to bear the legend set forth in Section 2.5(e), collectively, the “Restricted Securities”) shall be subject to the
restrictions on transfer set forth in this Section 2.5(d) (including the legend set forth below), unless such restrictions on transfer shall be waived by written consent of the Company, and the holder of each such Restricted Security, by such
holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in Sections 2.5(d) and 2.5(e), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted
Security. 
  
 Until two (2) years after the original issuance date
of any Note, any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof which shall bear the legend set forth in Section 2.5(e), if
applicable) shall bear a legend in substantially the following form (unless such Notes have been transferred pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the
time of such transfer) or unless otherwise agreed by the Company in writing, with notice thereof to the Trustee): 
  
 THE NOTE EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR ANY STATE
SECURITIES LAWS, AND MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A
“QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS AN INSTITUTIONAL “ACCREDITED INVESTOR” (AS DEFINED IN RULE 501(A)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT) (“INSTITUTIONAL
ACCREDITED INVESTOR”) OR (C) IT IS NOT A U.S. PERSON AND IS ACQUIRING THE NOTE EVIDENCED HEREBY IN AN OFFSHORE TRANSACTION; (2) AGREES THAT IT WILL NOT WITHIN TWO 
  

 -12- 

 YEARS AFTER THE ORIGINAL ISSUANCE OF THE NOTE EVIDENCED HEREBY RESELL OR OTHERWISE TRANSFER THE NOTE
EVIDENCED HEREBY OR THE COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH NOTE EXCEPT (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT,
(C) INSIDE THE UNITED STATES TO AN INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO SUNTRUST BANK, AS TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF
THE NOTE EVIDENCED HEREBY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM SUCH TRUSTEE), (D) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, (E) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER
THE SECURITIES ACT (IF AVAILABLE) OR (F) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER); AND (3) AGREES THAT IT WILL DELIVER TO EACH
PERSON TO WHOM THE NOTE EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(F) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF THE NOTE EVIDENCED HEREBY WITHIN TWO YEARS AFTER
THE ORIGINAL ISSUANCE OF SUCH NOTE (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(F) ABOVE), THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO SUNTRUST BANK,
AS TRUSTEE. IF THE PROPOSED TRANSFER IS PURSUANT TO CLAUSE 2(C) OR 2(E) ABOVE, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO SUNTRUST BANK, AS TRUSTEE SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE COMPANY OR THE TRUSTEE MAY
REASONABLY REQUIRE 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. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF
THE NOTE EVIDENCED HEREBY PURSUANT TO CLAUSE 2(F) ABOVE OR THE EXPIRATION OF TWO YEARS FROM THE ORIGINAL ISSUANCE OF THE NOTE EVIDENCED HEREBY. AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND “U.S.
PERSON” HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT. 
  
 Any Note (or security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of such Note for exchange to the Note
registrar in accordance with the provisions of this Section 2.5, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.5(d). 
  
 Notwithstanding any other provisions of this Indenture (other than the
provisions set forth in this Section 2.5(d)), a Note in global form may not be transferred as a whole or in part except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee

  

 -13- 

 of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor
Depositary. 
  
 The Depositary shall be a clearing agency
registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to the Notes in global form. Initially, the global Note shall be issued to the Depositary, registered in the name of
Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co. 
  
 If at any time the Depositary for the Note in global form notifies the Company that it is unwilling or unable to continue as Depositary for such Note, the
Company may appoint a successor Depositary with respect to such Note. If a successor Depositary for the Note is not appointed by the Company within ninety (90) days after the Company receives such notice, the Company will execute, and the Trustee,
upon receipt of an Officers’ Certificate for the authentication and delivery of Notes, will authenticate and deliver, Notes in definitive form, in an aggregate principal amount equal to the principal amount of the Note in global form, in
exchange for such Note in global form and upon delivery of such Note in global form to the Trustee such Note in global form shall be canceled. 
  
 Definitive Notes issued in exchange for all or a part of a Note in global form pursuant to this Section 2.5(d) shall be registered in such names and in
such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee in writing. Upon execution and authentication, the Trustee shall deliver such definitive
Notes to the persons in whose names such definitive Notes are so registered. 
  
 At such time as all interests in a Note in global form have been redeemed, converted, canceled, repurchased or transferred, such Note in global form shall be, upon receipt thereof, canceled by the Trustee in
accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a global Note is exchanged for definitive Notes, redeemed, converted, canceled,
repurchased or transferred to a transferee who receives definitive Notes therefor or any definitive Note is exchanged or transferred for part of a Note in global form, the principal amount of such Note in global form shall, in accordance with the
standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Note in global form, by the Trustee or the Custodian, at the
direction of the Trustee, to reflect such reduction or increase. 
  
 (e) Until two (2) years after the original issuance date of any Note, any stock certificate representing Common Stock issued upon conversion of such Note shall bear a legend in substantially the following form (unless such Common Stock has
been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer) or such Common Stock has been issued upon conversion of Notes that have been
transferred pursuant to a registration statement that has been declared effective under the Securities Act or unless otherwise agreed by the Company with written notice thereof to the Trustee and any transfer agent for the Common Stock): 

 
 THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S.
SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR ANY STATE SECURITIES LAWS, AND MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING
SENTENCE. THE HOLDER HEREOF AGREES THAT UNTIL THE EXPIRATION OF TWO YEARS AFTER THE ORIGINAL ISSUANCE OF THE NOTE UPON THE CONVERSION OF WHICH THE COMMON STOCK EVIDENCED HEREBY WAS 
  

 -14- 

 ISSUED, (1) IT WILL NOT RESELL OR OTHERWISE TRANSFER THE COMMON STOCK EVIDENCED HEREBY EXCEPT (A) TO THE
COMPANY OR ANY SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES TO A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN COMPLIANCE WITH RULE 144A, (C) INSIDE THE UNITED STATES TO AN INSTITUTIONAL
“ACCREDITED INVESTOR” (AS DEFINED IN RULE 501(A)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT) THAT PRIOR TO SUCH TRANSFER, FURNISHES TO SUNTRUST BANK, ATLANTA, AS TRANSFER AGENT, A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND
AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM SUCH TRANSFER AGENT), (D) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, (E)
PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE), OR (F) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH CONTINUES TO BE EFFECTIVE AT
THE TIME OF SUCH TRANSFER); (2) PRIOR TO ANY SUCH TRANSFER (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 1(F) ABOVE), IT WILL FURNISH TO SUNTRUST BANK, ATLANTA, AS TRANSFER AGENT, SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE COMPANY
MAY REASONABLY REQUIRE 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 (3) IT WILL DELIVER TO EACH PERSON TO WHOM THE COMMON
STOCK EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 1(F) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY
PURSUANT TO CLAUSE 1(F) ABOVE OR THE EXPIRATION OF TWO YEARS FROM THE ORIGINAL ISSUANCE OF THE NOTE UPON THE CONVERSION OF WHICH THE COMMON STOCK EVIDENCED HEREBY WAS ISSUED OR UPON THE EARLIER SATISFACTION OF SUNTRUST BANK, ATLANTA, AS TRANSFER
AGENT, THAT THE COMMON STOCK HAS BEEN OR IS BEING OFFERED AND SOLD IN COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT. AS USED HEREIN, THE TERMS “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S
UNDER THE SECURITIES ACT. 
  
 Any such Common Stock as to which
such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common
Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.5(e). 
  
 (f) Any certificate evidencing a Note that has been transferred to an
Affiliate of the Company within two years after the original issuance date of the Note, as evidenced by a notation on the Assignment Form for such transfer or in the representation letter delivered in respect thereof, for so long as such Note is
held by such Affiliate, shall, until three years after the last date on which the Company or 
  

 -15- 

 any Affiliate of the Company was an owner of such Note, in each case, bear a legend in substantially the following form,
unless otherwise agreed by the Company (with written notice thereof to the Trustee): 
  
 THE NOTE EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR
THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER AGREES (1) THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THE NOTE EVIDENCED HEREBY OR THE COMMON STOCK ISSUABLE UPON
CONVERSION OF SUCH NOTE EXCEPT (A) TO SUNTRUST BANK, ATLANTA OR ANY SUBSIDIARY THEREOF, (B) IN A TRANSACTION REGISTERED UNDER THE SECURITIES ACT OR (C) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF
AVAILABLE) AND (2) THAT IT WILL DELIVER TO EACH PERSON TO WHOM THE NOTE EVIDENCED HEREBY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. THIS LEGEND SHALL BE REMOVED UPON THE TRANSFER OF THE NOTE EVIDENCED HEREBY OR THE COMMON
STOCK ISSUABLE UPON CONVERSION OF SUCH NOTE PURSUANT TO THE IMMEDIATELY PRECEDING SENTENCE. IF THE PROPOSED TRANSFER IS PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT, THE HOLDER MUST, PRIOR TO SUCH
TRANSFER, FURNISH SUNTRUST BANK, AS TRUSTEE SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE COMPANY OR THE TRUSTEE MAY REASONABLY REQUIRE 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. AS USED HEREIN, THE TERMS “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT. 
  
 Any stock certificate representing Common Stock issued upon conversion of such Note shall
also bear a legend in substantially the form indicated above, unless otherwise agreed by the Company (with written notice thereof to the Trustee). 
  
 (g) Notwithstanding any provision of Section 2.5 to the contrary, in the event Rule 144(k) as promulgated under the Securities Act (or any successor rule)
is amended to shorten the two-year period under Rule 144(k) (or the corresponding period under any successor rule), from and after receipt by the Trustee of the Officers’ Certificate and Opinion of Counsel provided for in this Section 2.5(g),
(i) the references in the first sentence of the second paragraph of Section 2.5(d) to “two (2) years” and in the restrictive legend set forth in such paragraph to “TWO YEARS” shall be deemed for all purposes hereof to be
references to such shorter period, (ii) the references in the first paragraph of Section 2.5(e) to “two (2) years” and in the restrictive legend set forth in such paragraph to “TWO YEARS” shall be deemed for all purposes hereof
to be references to such shorter period and (iii) all corresponding references in the Notes and the restrictive legends thereon shall be deemed for all purposes hereof to be references to such shorter period, provided that such changes shall not
become effective if they are otherwise prohibited by, or would otherwise cause a violation of, the then-applicable federal securities laws. As soon as practicable after the Company has knowledge of the effectiveness of any such amendment to shorten
the two-year period under Rule 144(k) (or the corresponding period under any successor rule), unless such changes 
  

 -16- 

 would otherwise be prohibited by, or would otherwise cause a violation of, the then-applicable securities law, the
Company shall provide to the Trustee an Officers’ Certificate and Opinion of Counsel informing the Trustee of the effectiveness of such amendment and the effectiveness of the foregoing changes to Sections 2.5(d) and 2.5(e) and the Notes. The
provisions of this Section 2.5(g) will not be effective until such time as the Opinion of Counsel and Officers’ Certificate have been received by the Trustee hereunder. This Section 2.5(g) shall apply to successive amendments to Rule 144(k) (or
any successor rule) shortening the holding period thereunder. 
  
 Section 2.6 Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its request the Trustee or an authenticating agent
appointed by the Trustee shall authenticate and deliver, a new Note, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or
stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any
loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent
evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 
  
 The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such security or indemnity as
the Trustee, the Company and, if applicable, such authenticating agent may require. Upon the issuance of any substituted Note, 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 and any other expenses connected therewith. In case any Note which has matured or is about to mature or has been called for redemption or is about to be converted into Common Stock shall become mutilated or be destroyed, lost or
stolen, the Company may, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the
applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost
or expense caused by or connected with such substitution, and, in case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any paying agent or conversion agent of the destruction, loss or theft of
such Note and of the ownership thereof. 
  
 Every substitute Note
issued pursuant to the provisions of this Section 2.6 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be
found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law,
all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other
rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their surrender. 
  
 Section 2.7 Temporary Notes. Pending the preparation of definitive
Notes, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in
any authorized denomination, and substantially in the form of the definitive 
  

 -17- 

 Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be
determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the
definitive Notes. Without unreasonable delay the Company will execute and deliver to the Trustee or such authenticating agent definitive Notes (other than in the case of Notes in global form) and thereupon any or all temporary Notes (other than any
such Note in global form) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 5.2 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary
Notes an equal aggregate principal amount of definitive Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same
benefits and subject to the same limitations under this Indenture as definitive Notes authenticated and delivered hereunder. 
  
 Section 2.8 Cancellation of Notes Paid, Etc. All Notes surrendered for the purpose of payment, redemption, repurchase, conversion, exchange or
registration of transfer, shall, if surrendered to the Company or any paying agent or any Note registrar or any conversion agent, be surrendered to the Trustee and promptly canceled by it, or, if surrendered to the Trustee, shall be promptly
canceled by it, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. Upon written instructions of the Company, the Trustee shall destroy canceled Notes and, after such destruction,
shall deliver a certificate of such destruction to the Company. If the Company shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Notes unless and until the same
are delivered to the Trustee for cancellation. 
  
 ARTICLE III

  
 REDEMPTION OF NOTES 
  
 Section 3.1 Right of Redemption. (a) The Company may redeem some or
all of the Notes at any time at a redemption price of $1,000 per $1,000 principal amount of Notes, plus accrued and unpaid interest, if any, to the redemption date, plus the Interest Make-Whole Payment; provided that (1) the Closing Price of
the Common Stock has exceeded 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 immediately before the date of mailing of the redemption notice (the
“Redemption Notice Date”) and (2) the registration statement satisfying the requirements of the Registration Rights Agreement covering the Notes and the Common Stock issuable upon conversion of the Notes is effective and available for use
for the 30 days following the redemption date, unless registration is not required pursuant to the Registration Rights Agreement. 
  
 The Company will pay holders any accrued and unpaid interest through the date of redemption as well as the Interest Make-Whole Payment on the Notes called
for redemption, regardless of whether those Notes are converted prior to the date of the redemption. 
  
 (b) The Company may elect to pay all or a portion of the Interest Make-Whole Payment by delivery of shares of Common Stock pursuant to Section 3.1(a) if
and only if the following conditions shall have been satisfied: 
  
 (1) The shares of Common Stock deliverable to pay the Interest Make-Whole Payment shall have a fair market value as of the redemption date of not less than the amount of the Interest Make-Whole Payment. For purposes
of Section 3.1(b), the fair market value of shares of Common Stock shall be determined by the Company and shall be equal to 95% of the average of the Closing Prices of the Common Stock for the five 
  

 -18- 

 consecutive Trading Days immediately preceding the third Trading Day prior to the redemption date;

  
 (2) The Interest Make-Whole Payment shall be
paid only in cash in the event any shares of Common Stock to be issued upon redemption of Notes hereunder (i) require registration under any federal securities law before such shares may be freely transferable without being subject to any transfer
restrictions under the Securities Act upon redemption and if such registration is not completed or does not become effective prior to the redemption date, and/or (ii) require registration with or approval of any governmental authority under any
state law or any other federal law before such shares may be validly issued or delivered upon redemption and if such registration is not completed or does not become effective or such approval is not obtained prior to the redemption date;

  
 (3) The Interest Make-Whole Payment may not
be made in Common Stock unless such stock is, or shall have been, approved for quotation on the Nasdaq National Market or listed on a national securities exchange, in either case, prior to the redemption date; and 
  
 (4) All shares of Common Stock which may be issued upon
repurchase of the Notes will be issued out of the Company’s authorized but unissued Common Stock and, will upon issue, be duly and validly issued and fully paid and non- assessable and free of any preemptive rights. 
  
 If all of the conditions set forth in this Section 3.1(b) are not satisfied
in accordance with the terms thereof, the Interest Make-Whole Payment shall be paid by the Company only in cash. In the event the Company elects to pay only a portion of the Interest Make-Whole Payment in Common Stock, the Company shall pay the
remaining balance of the Interest Make-Whole Payment in cash. 
  
 Section 3.2 Notice of Redemption; Selection of Notes. In case the Company shall desire to exercise the right to redeem all or, as the case may be, any part of the Notes pursuant to Section 3.1, it shall fix a date for redemption, and
it, or at its request (which must be received by the Trustee at least ten (10) Business Days prior to the date the Trustee is requested to give notice as described below unless a shorter period is agreed to by the Trustee), the Trustee in the name
of and at the expense of the Company, shall mail or cause to be mailed a notice of such redemption at least thirty (30) and not more than (60) days prior to the date fixed for redemption to the holders of Notes so to be redeemed as a whole or in
part at their last addresses as the same appear on the Note register (provided that if the Company shall give such notice, it shall also give such notice, and notice of the Notes to be redeemed, to the Trustee). Such mailing shall be by first
class mail. The notice if mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to
the holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. 
  
 Each such notice of redemption shall specify the aggregate principal amount of Notes to be redeemed, the date fixed for redemption, the redemption price
at which Notes are to be redeemed, the place or places of payment, that payment will be made upon presentation and surrender of such Notes, that interest accrued to, but excluding, the date fixed for redemption will be paid as specified in said
notice, and that on and after said date interest thereon or on the portion thereof to be redeemed will cease to accrue unless the Company defaults in its obligation thereto. Such notice shall also state the current Conversion Price and the date on
which the right to convert such Notes or portions thereof into Common Stock will expire. If fewer than all the Notes are to be redeemed, the notice of redemption shall identify the Notes to 
  

 -19- 

 be redeemed. In case any Note is to be redeemed in part only, the notice of redemption shall state the portion of the
principal amount thereof to be redeemed and shall state that on and after the date fixed for redemption, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion thereof will be issued. 
  
 On or prior to the redemption date specified in the notice of redemption
given as provided in this Section, the Company will deposit with the Trustee or with one or more paying agents (or, if the Company is acting as its own paying agent, set aside, segregate and hold in trust as provided in Section 5.4) an amount of
money (or, at the Company’s option, Common Stock with respect to the Interest Make-Whole Payment) sufficient to redeem on the redemption date all the Notes (or portions thereof) so called for redemption (other than those theretofore surrendered
for conversion into Common Stock) at the appropriate redemption price, together with accrued interest to and including the date fixed for redemption, and the Interest Make-Whole Payment; provided that if such payment is made on the redemption
date it must be received by the Trustee or paying agent, as the case may be, by 10:00 a.m. New York City time, on such date. If any Note called for redemption is converted pursuant hereto, any money deposited with the Trustee or any paying agent or
so segregated and held in trust for the redemption of such Note shall be paid to the Company upon its request, or, if then held by the Company shall be discharged from such trust. 
  
 If fewer than all the Notes are to be redeemed, the Company will give the Trustee written notice in the form of an
Officers’ Certificate not fewer than thirty-five (35) days (or such shorter period of time as may be acceptable to the Trustee) prior to the redemption date as to the aggregate principal amount of Notes to be redeemed. If fewer than all the
Notes are to be redeemed, the Trustee shall select the Notes or portions thereof to be redeemed (in principal amounts of $1,000 or integral multiples thereof), by lot, on a pro rata basis, or in any other manner the Trustee may select. If any Note
selected for partial redemption is converted in part after such selection, the converted portion of such Note shall be deemed (so far as may be) to be the portion to be selected for redemption. The Notes (or portions thereof) so selected shall be
deemed duly selected for redemption for all purposes hereof, notwithstanding that any such Note is converted as a whole or in part before the mailing of the notice of redemption. 
  
 Upon any redemption of less than all Notes, the Company and the Trustee may (but need not) treat as outstanding any Notes
surrendered for conversion during the period of fifteen (15) days next preceding the mailing of a notice of redemption and may (but need not) treat as not outstanding any Note authenticated and delivered during such period in exchange for the
unconverted portion of any Note converted in part during such period. Notwithstanding anything else contained in this Section 3.2, the parties hereto acknowledge and agree that any partial redemption of a Note in global form shall be made by the
Depositary among the holders of the beneficial interests therein in accordance with the rules and regultions of the Depositary and that the Trustee shall have no liability in connection with the selection of beneficial interests in the Notes in
global form in connection with any such redemption or any other actions taken by the Depositary in connection therewith, and by accepting the Notes, the holders shall waive and release such liability. 
  
 Section 3.3 Payment of Notes Called for Redemption. If notice of
redemption has been given as above provided, the Notes or portion of Notes with respect to which such notice has been given shall, unless converted into Common Stock pursuant to the terms hereof, become due and payable on the date and at the place
or places stated in such notice at the applicable redemption price, together with interest accrued to and including the date fixed for redemption, and the Interest Make-Whole Payment and on and after said date (unless the Company shall default in
the payment of such Notes at the redemption price, together with interest accrued to, but excluding, said date) interest on the Notes or portion of Notes so called for redemption shall cease to accrue and such Notes shall cease after the close of
business on the Business Day next preceding the date fixed for redemption to be convertible into Common Stock and, 
  

 -20- 

 except as provided in Sections 8.5 and 13.4, to be entitled to any benefit or security under this Indenture, and the
holders thereof shall have no right in respect of such Notes except the right to receive the redemption price thereof and unpaid interest to, to and including the date fixed for redemption, and the Interest Make-Whole Payment. On presentation and
surrender of such Notes at a place of payment in said notice specified, the said Notes or the specified portions thereof to be redeemed shall be paid and redeemed by the Company at the applicable redemption price, together with interest accrued
thereon to and including the date fixed for redemption, and the Interest Make-Whole Payment; provided that, if the applicable redemption date is an interest payment date, the semi-annual payment of interest becoming due on such date shall be
payable to the holders of such Notes registered as such on the relevant record date subject to the terms and provisions of Section 2.3 hereof. 
  
 Upon presentation of any Note redeemed in part only, the Company shall execute and the Trustee shall authenticate and deliver to the holder thereof, at
the expense of the Company, a new Note or Notes, of authorized denominations, in principal amount equal to the unredeemed portion of the Notes so presented. 
  
 Notwithstanding the foregoing, the Trustee shall not redeem any Notes or mail any notice of optional redemption during the continuance of a default in
payment of interest or premium on the Notes or of any Event of Default of which, in the case of any Event of Default other than under Section 7.1(a) or (b), a Responsible Officer of the Trustee has actual knowledge. If any Note called for redemption
shall not be so paid upon surrender thereof for redemption, the principal and premium, if any, shall, until paid or duly provided for, bear interest from the date fixed for redemption at the rate borne by the Note and such Note shall remain
convertible into Common Stock until the principal and premium, if any, shall have been paid or duly provided for. 
  
 Section 3.4 Conversion Arrangement on Call for Redemption. In connection with any redemption of Notes, the Company may arrange for the purchase and
conversion of any Notes by an agreement with one or more investment bankers or other purchasers to purchase such Notes by paying to the Trustee in trust for the Noteholders, on or before the date fixed for redemption, an amount not less than the
applicable redemption price, together with interest accrued to and including the date fixed for redemption, and the Interest Make-Whole Payment, of such Notes. Notwithstanding anything to the contrary contained in this Article III, the obligation of
the Company to pay the redemption price of such Notes, together with interest accrued to, but excluding, the date fixed for redemption, 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, certified as true and correct by the Secretary or Assistant Secretary of the Company will be filed with the Trustee prior to the date fixed for redemption, any Notes 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, acquired by such purchasers from such holders and (notwithstanding anything to the contrary contained in Article XV) surrendered by such
purchasers for conversion, all as of immediately prior to the close of business on the date fixed for redemption (and the right to convert any such Notes shall be deemed to have been extended through such time), subject to payment of the above
amount as aforesaid. At the written direction of the Company, the Trustee shall hold and dispose of any such amount paid to it in the same manner as it would monies deposited with it by the Company for the redemption of Notes. Without the
Trustee’s prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any Notes shall increase or otherwise affect any of the powers, duties, responsibilities, liabilities 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 Notes between the Company and such purchasers to which the Trustee has not consented in writing, including the costs and expenses incurred by the Trustee in the defense of any claim or liability arising out 
  

 -21- 

 of or in connection with the exercise or performance of any of its powers, duties, responsibilities or obligations under
this Indenture. 
  
 ARTICLE IV 
  
 SUBORDINATION OF NOTES 
  
 Section 4.1 Agreement of Subordination. The Company covenants and
agrees, and each holder of Notes issued hereunder by his acceptance thereof likewise covenants and agrees, that all Notes shall be issued subject to the provisions of this Article IV; and each person holding any Note, whether upon original issue or
upon transfer, assignment or exchange thereof, accepts and agrees to be bound by such provisions. 
  
 The payment of the principal of, premium, if any, and interest on all Notes (including, but not limited to, the redemption price or repurchase price with
respect to the Notes to be redeemed or repurchased, as provided in this Indenture) issued hereunder shall, to the extent and in the manner hereinafter set forth, be subordinated to the prior payment in full in cash or in such other form of payment
as may be acceptable to the holders of Senior Indebtedness of all Senior Indebtedness, whether outstanding at the date of this Indenture or thereafter incurred or created. 
  
 No provision of this Article IV shall prevent the occurrence of any default or Event of Default hereunder. 
  
 Section 4.2 Payments to Noteholders. No payment (including pursuant to
any redemption or repurchase of Notes) shall be made with respect to the principal of, or premium, if any, or interest (including Liquidated Damages, if any) on the Notes, except payments and distributions made by the Trustee as permitted by Section
4.6, if: 
  
 (1) a default in the payment of
principal, premium, if any, or interest or other payment due on Senior Indebtedness occurs and is continuing beyond any applicable period of grace; or 
  
 (2) any other default occurs and is continuing with respect to Designated Senior Indebtedness that then permits holders of the Designated
Senior Indebtedness as to which such default related to accelerate its maturity and the Trustee and the Company receive a notice of such default (a “Payment Blockage Notice”) from a Representative of Designated Senior Indebtedness.

  
 The Company may and shall resume payments on the Notes (1) in
the case of a payment default, on the date upon which such default is cured or waived or ceases to exist, and (2) in the case of a nonpayment default with respect to Designated Senior Indebtedness, on the earlier of the date on which the nonpayment
default is cured or waived or ceases to exist or 179 days pass after the date on which the applicable Payment Blockage Notice is received. 
  
 No new period of payment blockage may be commenced pursuant to a Payment Blockage Notice unless (A) at least 365 days shall have elapsed since the first
day of effectiveness of the immediately prior Payment Blockage Notice and (B) all scheduled payments of principal, premium, if any, and interest on the Notes that have come due have been paid in full in cash, or in such other form of payment as may
be acceptable to the holders of the Notes or the Trustee or the holder of the Notes shall have instituted proceedings to enforce such holders’ rights to receive such payments. No default (whether or not such event of default is on the same
issue of Designated Senior Indebtedness) that existed or was continuing on the 
  

 -22- 

 date of delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment
Blockage Notice. 
  
 In addition, in the event of any acceleration
of the Notes because of an Event of Default, no payment or distribution (including with respect to any redemption or repurchase of the Notes) shall be made to the Trustee or any holder of Notes with respect to the principal of, premium, if any, or
interest (including Liquidated Damages, if any) on the Notes, except payments and distributions made by the Trustee as permitted by Section 4.6, until all Senior Indebtedness has been paid in full in cash or other payment satisfactory to the holders
of Senior Indebtedness or such acceleration is rescinded in accordance with the terms of this Indenture. If payment of the Notes is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Indebtedness of the
acceleration. 
  
 In the event that, notwithstanding the
foregoing, the Trustee or any holder of Notes receives any payment or distribution of assets of the Company of any kind in contravention of any term of this Indenture, whether in cash, property or securities, including, without limitation, by way of
setoff or otherwise, before all Senior Indebtedness is paid in full, in cash or such other form of payment as may be acceptable to the holders of Senior Indebtedness, then such payment or distribution shall be held by the recipient or recipients in
trust for the benefit of, and shall be paid over or delivered to, the holders of Senior Indebtedness or their respective representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments
evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, as calculated by the Company, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to make payment in
full, in cash or such other form of payment as may be acceptable to the holders of Senior Indebtedness, of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution, or provision therefor, to or for the
holders of such Senior Indebtedness. 
  
 Nothing in this Section
4.2 shall apply to claims of, or payments to, the Trustee pursuant to Section 8.6. This Section 4.2 shall be subject to the further provisions of Section 4.6. 
  

Section 4.3 Bankruptcy and Dissolution, Etc. Upon any payment by the Company, or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to creditors upon any dissolution, winding-up, liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings, all amounts due
or to become due upon all Senior Indebtedness shall first be paid in full, in cash or in such other form of payment as may be acceptable to the holders of Senior Indebtedness, before any payment is made on account of the principal or premium, if
any, and interest on the Notes (except payments made pursuant to Article XIII from monies deposited with the Trustee pursuant thereto prior to the happening of such dissolution, winding-up, liquidation or reorganization or bankruptcy, insolvency,
receivership or other such proceedings); and upon any such dissolution, winding-up, liquidation or reorganization or bankruptcy, insolvency, receivership or other such proceedings, any payment by the Company, or distribution of assets of the Company
of any kind or character, whether in cash, property or securities, to which the holders of the Notes or the Trustee under this Indenture would be entitled, except for the provision of this Article IV, shall (except as aforesaid) be paid by the
Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, or by the holders of the Notes or by the Trustee under this Indenture if received by them or it, directly to the
holders of Senior Indebtedness (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness held by such holders, or as otherwise required by law or a court order) or their respective representative or representatives, or
to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay all Senior Indebtedness in full in
cash or in such other form of payment as may be acceptable to the holders 
  

 -23- 

 of Senior Indebtedness after giving effect to any concurrent payment or distribution to or for the holders of Senior
Indebtedness, before any payment or distribution is made to the holders of the Notes or to the Trustee under this Indenture. 
  
 In the event that, notwithstanding the foregoing, the Trustee or any holder of Notes receives any payment or distribution of assets of the Company of any
kind in contravention of any term of this Indenture, whether in cash, property or securities, including, without limitation, by way of setoff or otherwise, before all Senior Indebtedness is paid in full, in cash or such other form of payment as may
be acceptable to the holders of Senior Indebtedness, then such payment or distribution shall be held by the recipient or recipients in trust for the benefit of, and shall be paid over or delivered to, the holders of Senior Indebtedness or their
respective representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, as calculated by the
Company, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to make payment in full, in cash or such other form of payment as may be acceptable to the holders of Senior Indebtedness, of all Senior
Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution, or provision therefor, to or for the holders of such Senior Indebtedness. 
  
 For purposes of this Section 4.3, the words “cash, property or securities” shall not be deemed to include shares
of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated (at least to the extent provided in this
Article IV with respect to the Notes) to the payment of all Senior Indebtedness which may at the time be outstanding; provided that (i) the Senior Indebtedness is assumed by the new corporation, if any, resulting from such reorganization or
adjustment, and (ii) the rights of the holders of Senior Indebtedness (other than leases which are not assumed by the Company or by the new corporation, as the case may be) are not, without the consent of such holders, altered by such reorganization
or readjustment. The consolidation of the Company with, or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance or transfer of its property as an entirety, or substantially as
an entirety, to another corporation upon the terms and conditions provided for in Article XII shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section 4.3 if such other corporation shall, as a
part of such consolidation, merger, conveyance or transfer, comply with the conditions stated in Article XII. 
  
 Nothing in this Section 4.3 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 8.6. This Section 4.3 shall be subject to
the further provisions of Section 4.6. 
  
 Section 4.4
Subrogation of Notes. Subject to the payment in full in cash or in such other form of payment as may be acceptable to the holders of Senior Indebtedness of all Senior Indebtedness, the rights of the holders of the Notes shall be subrogated to
the extent of the payments or distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article IV (equally and ratably with the holders of all indebtedness of the Company which by its express terms is
subordinated to other indebtedness of the Company to substantially the same extent as the Notes are subordinated and is entitled to like rights of subrogation) to the rights of the holders of Senior Indebtedness to receive payments or distributions
of cash, property or securities of the Company applicable to the Senior Indebtedness until the principal of (and premium, if any) and interest on the Notes shall be paid in full; and, for the purposes of such subrogation, no payments or
distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the holders of the Notes or the Trustee would be entitled except for the provisions of this Article IV, and no payment over pursuant to the
provisions of this Article IV, to or for the benefit of the holders of Senior Indebtedness by holders of the Notes or the Trustee, shall, as between the Company, its creditors other than holders of Senior Indebtedness, and the holders of the

  

 -24- 

 Notes, be deemed to be a payment by the Company to or on account of the Senior Indebtedness; and no payments or
distributions of cash, property or securities to or for the benefit of the holders of the Notes pursuant to the subrogation provisions of this Article IV, which would otherwise have been paid to the holders of Senior Indebtedness shall be deemed to
be a payment by the Company to or for the account of the Notes. It is understood that the provisions of this Article IV are and are intended solely for the purposes of defining the relative rights of the holders of the Notes, on the one hand, and
the holders of the Senior Indebtedness, on the other hand. 
  
 Nothing contained in this Article IV or elsewhere in this Indenture or in the Notes is intended to or shall impair, as among the Company, its creditors other than the holders of Senior Indebtedness, and the holders of the Notes, the
obligation of the Company, which is absolute and unconditional, to pay to the holders of the Notes the principal of (and premium, if any) and interest on the Notes as and when the same shall become due and payable in accordance with their terms, or
is intended to or shall affect the relative rights of the holders of the Notes and creditors of the Company other than the holders of the Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or the holder of any Note from
exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article IV of the holders of Senior Indebtedness in respect of cash, property or securities of the Company
received upon the exercise of any such remedy. 
  
 Upon any
payment or distribution of assets of the Company referred to in this Article IV, the Trustee, subject to the provisions of Section 8.1, and the holders of the Notes shall be entitled to rely upon any order or decree made by any court of competent
jurisdiction in which such bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or
distribution, delivered to the Trustee or to the holders of the Notes, for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of the Senior Indebtedness 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 IV. 
  
 Section 4.5 Authorization by Noteholders. Each holder of a Note by his acceptance thereof authorizes and directs the Trustee on his behalf to take
such action as may be necessary or appropriate to effectuate the subordination provided in this Article IV and appoints the Trustee his attorney-in-fact for any and all such purposes. 
  
 Section 4.6 Notice to Trustee. The Company shall give written notice to the Trustee of the issuance of any Designated
Senior Indebtedness. In addition, the Company shall give prompt written notice in the form of an Officers’ Certificate to a Responsible Officer of the Trustee and to any paying agent of any fact known to the Company which would prohibit the
making of any payment of monies to or by the Trustee or any paying agent in respect of the Notes pursuant to the provisions of this Article IV. Notwithstanding the provisions of this Article IV or any other provision of this Indenture, the Trustee
shall not be charged with knowledge of the existence of any Senior Indebtedness or of any default or event of default with respect to any Senior Indebtedness or of any other facts which would prohibit the making of any payment of monies to or by the
Trustee in respect of the Notes pursuant to the provisions of this Article IV, unless and until a Responsible Officer of the Trustee shall have received written notice thereof at the Corporate Trust Office from the Company (in the form of an
Officers’ Certificate) or a holder or holders of Senior Indebtedness or from any trustee thereof who shall have been certified by the Company or otherwise established to the reasonable satisfaction of the Trustee to be such holder or trustee;
and before the receipt of any such written notice, the Trustee, subject to the provisions of Section 8.1, shall be entitled in all respects to assume that no such facts exist; provided that if on a date at least two (2) Business Days prior to
the date upon which by the terms hereof any such monies may become payable for 
  

 -25- 

 any purpose (including, without limitation, the payment of the principal of, or premium, if any, or interest on any
Note), the Trustee shall not have received with respect to such monies the notice provided for in this Section 4.6, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such
monies and to apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may be received by it on or after such prior date. 
  
 Notwithstanding anything to the contrary hereinbefore set forth, nothing shall prevent (a) any payment by the Company or the
Trustee to the Noteholders of amounts in connection with a redemption of Notes if (i) notice of such redemption has been given pursuant to Article III prior to the receipt by the Trustee of written notice as aforesaid, and (ii) such notice of
redemption is given not earlier than (60) days before the redemption date, (b) any payment by the Company or the Trustee to the Noteholders of amounts in connection with a repurchase of Notes if (i) notice of such repurchase has been given pursuant
to Article XVI prior to the receipt by the Trustee of written notice as aforesaid, and (ii) such notice of repurchase is given not earlier than forty (40) days before the repurchase date, or (c) any payment by the Trustee to the Noteholders of
monies deposited with it pursuant to Section 13.1. 
  
 The
Trustee, subject to the provisions of Section 8.1, shall be entitled to rely on the delivery to it of a written notice by a person representing himself to be a holder of Senior Indebtedness (or a trustee on behalf of such holder) to establish that
such notice has been given by a holder of Senior Indebtedness or a trustee on behalf of any such holder or holders. 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 Indebtedness to participate in any payment or distribution pursuant to this Article IV, the Trustee may request such person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
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 IV, 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 4.7 Trustee’s Relation to Senior Indebtedness. The Trustee and any agent of the Company or the Trustee in its individual capacity
shall be entitled to all the rights set forth in this Article IV in respect of any Senior Indebtedness at any time held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in Section 8.13 or elsewhere in this Indenture
shall deprive the Trustee or any such agent of any of its rights as such holder. Nothing in this Article IV shall apply to claims of, or payments to, the Trustee under or pursuant to Section 8.6. 
  
 With respect to the holders of Senior Indebtedness, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are specifically set forth in this Article IV, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Indenture against
the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and, subject to the provisions of Section 4.2 and Section 8.1, the Trustee shall not be liable to any holder of Senior Indebtedness if it
shall pay over or deliver to holders of Notes, the Company or any other person money or assets to which any holder of Senior Indebtedness shall be entitled by virtue of this Article IV or otherwise. 
  
 Section 4.8 No Impairment of Subordination. No right of any present or
future holder of any Senior Indebtedness 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 act or failure to act, in good faith, by
any such holder, or by any noncompliance by the Company with the terms, provisions and 
  

 -26- 

 covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged
with. 
  
 Section 4.9 Certain Conversions Deemed Payment.
For the purposes of this Article only, (1) the issuance and delivery of junior securities upon conversion of Notes in accordance with Article XV shall not be deemed to constitute a payment or distribution on account of the principal of (or premium,
if any) or interest on Notes or on account of the purchase or other acquisition of Notes, and (2) the payment, issuance or delivery of cash, property or securities (other than junior securities) upon conversion of a Note shall be deemed to
constitute payment on account of the principal of such Note. For the purposes of this Section, the term “junior securities” means (a) shares of any stock of any class of the Company and (b) securities of the Company which are subordinated
in right of payment to all Senior Indebtedness which 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 Notes are so subordinated as provided in this
Article. Nothing contained in this Article or elsewhere in this Indenture or in the Notes is intended to or shall impair, as among the Company, its creditors other than holders of Senior Indebtedness and the holders of the Notes, the right, which is
absolute and unconditional, of the holder of any Note to convert such Note in accordance with Article XV.

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

forthwith pay to the Trustee all sums so held in trust. 
  
 The
Company shall, on or before each due date of the principal of, premium, if any, or interest on the Notes, deposit with the paying agent a sum sufficient to pay such principal, premium, if any, or interest, and (unless such paying agent is the
Trustee) the Company will promptly notify the Trustee of any failure to take such action, provided that if such deposit is made on the due date, such deposit must be received by the paying agent by 10:00 a.m., New York City time, on such date.

  
 (b) If the Company shall act as its own paying agent, it will,
on or before each due date of the principal of, premium, if any, or interest on the Notes, set aside, segregate and hold in trust for the benefit of the holders of the Notes a sum sufficient to pay such principal, premium, if any, or interest so
becoming due and will notify the Trustee of any failure to take such action and of any failure by the Company (or any other obligor under the Notes) to make any payment of the principal of, premium, if any, or interest on the Notes when the same
shall become due and payable. 
  
 (c) Anything in this Section 5.4
to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or any
paying agent hereunder as required by this Section 5.4, such sums to be held by the Trustee upon the trusts herein contained and upon such payment by the Company or any paying agent to the Trustee, the Company or such paying agent shall be released

purchaser of Notes or such Common Stock from such holder or beneficial holder, the information required pursuant to Rule 144A(d)(4) under the Securities Act upon the request of any holder or beneficial holder of the Notes or such Common Stock and it
will take such further action as any holder or beneficial holder of such Notes or such Common Stock may reasonably request, all to the extent required from time to time to enable such holder or beneficial holder to sell its Notes or Common Stock
without registration under the Securities Act within the limitation of the exemption provided by Rule 144A, as such rule may be amended from time to time. Upon the request of any holder or any beneficial holder of the Notes or such Common Stock, the
Company will deliver to such holder a written statement as to whether it has complied with such requirements.

upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Notes
as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such

$10,000,000, and the continuance of such failure for a period of thirty (30) days after there shall have been given, by registered or certified mail, to the Company 
  
  
  

 -31- 

 by the Trustee or to the Company and the Trustee by the holders of not less than 25% in aggregate
principal amount of the Notes then outstanding, a written notice specifying such default and requiring the Company to cause such default to be cured or waived and stating that such notice is a “Notice of Default” hereunder; or

and such Indebtedness shall not have been discharged or such acceleration shall not have been cured, waived, rescinded or annulled for a period of thirty (30) days after there shall have been given, by registered or certified mail, to the Company by

or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of ninety (90) consecutive days; 
  
 then, and in each and every such case (other than an Event of Default specified in Section 7.1(h) or (i)), unless the principal of all of
the Notes shall have already become due and payable, either the Trustee or the holders of not less than 25% in aggregate principal amount of the Notes then outstanding hereunder determined in accordance with Section 9.4, by notice in writing to the
Company (and to the Trustee if given by Noteholders), may declare the principal of and premium, if any, on all the Notes and the interest accrued thereon to be due and payable immediately, and upon any such declaration the same shall become and
shall be immediately due and payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding. If an Event of Default specified in Section 7.1(h) or (i) occurs and is continuing, the principal of all the Notes and the
interest accrued thereon shall be immediately due and payable. This provision, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree
for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest upon all Notes and the principal of
and premium, if any, on any and all Notes which shall have become due otherwise than by acceleration (with interest on overdue installments of interest (to the extent that payment of such interest is enforceable under applicable law) and on such
principal and premium, if any, at the rate borne by the Notes, to the date of such payment or deposit) and amounts due to the Trustee pursuant to Section 8.6, and if any 
  
  
  

 -32- 

 and all defaults under this Indenture, other than the nonpayment of principal of and premium, if any, and accrued
interest on Notes which shall have become due by acceleration, shall have been cured or waived pursuant to Section 7.7, then and in every such case the holders of a majority in aggregate principal amount of the Notes then outstanding, by written
notice to the Company and to the Trustee, may waive all defaults or Events of Default and rescind and annul such declaration and its consequences; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default
or Event of Default, or shall impair any right consequent thereon. The Company shall notify the Responsible Officer of the Trustee, promptly upon becoming aware thereof, of any Event of Default. 
  
 In case the Trustee shall have proceeded to enforce any right under this
Indenture and such proceedings shall have been discontinued or abandoned because of such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the
holders of Notes, and the Trustee shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the holders of Notes, and the Trustee shall continue as though no such proceeding
had been instituted. 
  
 Section 7.2 Payments of Notes on
Default; Suit Therefor. The Company covenants that (a) in case default shall be made in the payment by the Company of any installment of interest upon any of the Notes as and when the same shall become due and payable, and such default shall
have continued for a period of thirty (30) days, or (b) in case default shall be made in the payment of the principal of or premium, if any, on any of the Notes as and when the same shall have become due and payable, whether at maturity of the Notes
or in connection with any redemption or repurchase, by declaration under this Indenture or otherwise, then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the holders of the Notes, the whole amount that then
shall have become due and payable on all such Notes for principal and premium, if any, or interest, or both, as the case may be, with interest upon the overdue principal and premium, if any, and (to the extent that payment of such interest is
enforceable under applicable law) upon the overdue installments of interest at the rate borne by the Notes; and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable
compensation (including expenses) to the Trustee, its agents, attorneys and counsel, and any expenses or liabilities incurred by the Trustee hereunder other than through its gross negligence or bad faith. Until such demand by the Trustee, the
Company may pay the principal of and premium, if any, and interest on the Notes to the registered holders, whether or not the Notes are overdue. 
  
 In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be
entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or
final decree against the Company or any other obligor on the Notes and collect in the manner provided by law out of the property of the Company or any other obligor on the Notes wherever situated the monies adjudged or decreed to be payable.

  
 In the case there shall be pending proceedings for the
bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the case of any other judicial proceedings relative to the Company or
such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 7.2, shall be entitled and empowered, 
  

 -33- 

 by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal,
premium, if any, and interest owing and unpaid in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee
and of the Noteholders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable
on any such claims, and to distribute the same after the deduction of any amounts due the Trustee under Section 8.6; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby
authorized by each of the Noteholders to make such payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to the Noteholders, to pay to the Trustee any amount due it for reasonable
compensation, expenses, advances and disbursements, including agents and counsel fees and expenses incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements
out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property which the holders of
the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. 
  
 All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any
of the Notes, or the production thereof on any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the holders of the Notes. 
  
 In any proceedings brought by the Trustee (and in any proceedings involving
the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the holders of the Notes, and it shall not be necessary to make any holders of the Notes parties to any such
proceedings. 
  
 Section 7.3 Application of Monies Collected by
Trustee. Any monies collected by the Trustee pursuant to this Article VII shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and
stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 
  
 First: To the payment of all amounts due the Trustee under Section 8.6; 
  
 Second: Subject to the provisions of Article IV, in case the principal of the outstanding Notes shall not
have become due and be unpaid, to the payment of interest on the Notes in default in the order of the maturity of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the overdue
installments of interest at the rate borne by the Notes, such payments to be made ratably to the persons entitled thereto; 
  
 Third: Subject to the provisions of Article IV, in case the principal of the outstanding Notes shall have become due, by declaration or
otherwise, and be unpaid, to the payment of the whole amount then owing and unpaid upon the Notes for principal and premium, if any, and interest, with interest on the overdue principal and premium, if any, and (to the extent that such interest has
been collected by the Trustee) upon overdue installments of interest at the rate borne by the Notes; and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such
principal and premium, if any, and interest without preference or priority of principal and premium, if any, over interest, or of interest 
  
  

 -34- 

 over principal and premium, if any, or of any installment of interest over any other installment of
interest, or of any Note over any other Note, ratably to the aggregate of such principal and premium, if any, and accrued and unpaid interest; and 
  
 Fourth: Subject to the provisions of Article IV, to the payment of the remainder, if any, to the Company or any other person lawfully
entitled thereto. 
  
 Section 7.4 Proceedings by
Noteholder. No holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the
appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance
thereof, as hereinbefore provided, and unless also the holders of not less than 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own
name as Trustee hereunder and shall have offered to the Trustee such indemnity as may be reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for (60) days after its
receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section
7.7; it being understood and intended, and being expressly covenanted by the taker and holder of every Note with every other taker and holder and the Trustee, that no one or more holders of Notes 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 holder of Notes, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this
Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all holders of Notes (except as otherwise provided herein). For the protection and enforcement of this Section 7.4, each and every Noteholder and the
Trustee shall be entitled to such relief as can be given either at law or in equity. 
  
 Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any holder of any Note to receive payment of the principal of and premium, if any, and interest on such Note, on or
after the respective due dates expressed in such Note, or to institute suit for the enforcement of any such payment on or after such respective dates against the Company shall not be impaired or affected without the consent of such holder.

  
 Anything in this Indenture or the Notes to the contrary
notwithstanding, the holder of any Note, without the consent of either the Trustee or the holder of any other Note, in his own behalf and for his own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, his rights
of conversion as provided herein. 
  
 Section 7.5 Proceedings
by Trustee. In case of an Event of Default the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect
and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any
power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 
  
 Section 7.6 Remedies Cumulative and Continuing. Except as provided in Section 2.6, all powers and remedies given by this Article VII to the Trustee
or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the holders of the Notes, by judicial proceedings or otherwise, to
enforce 
  

 -35- 

 the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of
the Trustee or of any holder of any of the Notes to exercise any right or power accruing upon any default or Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any
such default or any acquiescence therein; and, subject to the provisions of Section 7.4, every power and remedy given by this Article VII or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be
deemed expedient, by the Trustee or by the Noteholders. 
  
 Section 7.7 Direction of Proceedings and Waiver of Defaults by Majority of Noteholders. The holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 9.4 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, however, that (a) such direction shall not be in
conflict with any rule of law or with this Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. The holders of a majority in aggregate principal amount of the Notes at
the time outstanding determined in accordance with Section 9.4 may on behalf of the holders of all of the Notes waive any past default or Event of Default hereunder and its consequences except (i) a default in the payment of interest or premium, if
any, on, or the principal of, the Notes when due, (ii) a failure by the Company to convert any Notes into Common Stock or (iii) a default in respect of a covenant or provisions hereof which under Article XI cannot be modified or amended without the
consent of the holders of all Notes then outstanding. Upon any such waiver the Company, the Trustee and the holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon. Whenever any default or Event of Default hereunder shall have been waived as permitted by this Section 7.7, said default or Event of Default shall for all purposes of the
Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. 
  
 Section 7.8 Notice of Defaults. The Trustee shall, within thirty (30)
days after the Trustee has actual knowledge of the occurrence of a default or after the occurrence of a default in the payment of the principal, premium or interest on the Notes, mail to all Noteholders, as the names and addresses of such holders
appear upon the Note register, notice of all defaults known to a Responsible Officer, unless such defaults shall have been cured or waived before the giving of such notice; and provided that, except in the case of default in the payment of the
principal of, or premium, if any, or interest on any of the Notes, the Trustee shall be protected in withholding such notice if and so long as a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the
withholding of such notice is in the interests of the Noteholders. 
  
 Section 7.9 Undertaking to Pay Costs. All parties to this Indenture agree, and each holder of any Note by his acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such
court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided
that the provisions of this Section 7.9 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than 10% in principal amount of the Notes at the time
outstanding determined in accordance with Section 9.4, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or premium, if any, or interest on any Note (including, but not limited to, the redemption
price or repurchase price with respect to the Notes being 
  
  
  

 -36- 

 redeemed or repurchased as provided in this Indenture) on or after the due date expressed in such Note or to any suit for
the enforcement of the right to convert any Note in accordance with the provisions of Article XV. 
  
 Section 7.10 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any holder of any Note 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 or by law to the Trustee or to the holders of
Notes may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the holders of Notes, as the case may be. 
  
 ARTICLE VIII 
  
 CONCERNING THE TRUSTEE 
  
 Section 8.1 Duties and Responsibilities of Trustee. Notwithstanding anything herein to the contrary, the Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default
which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived) the Trustee shall exercise such of the
rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. 
  
 No provision of this Indenture shall be construed to relieve the Trustee from
liability for its own negligent action, its own gross negligent failure to act or its own willful misconduct, except that 
  
 (a) prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred:

  
 (1) the duties and obligations of the Trustee
shall be determined solely by the express provisions of this Indenture and the Trust Indenture Act, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no
implied covenants or obligations shall be read into this Indenture and the Trust Indenture Act against the Trustee; and 
  
 (2) in the absence of bad faith and willful misconduct on the part of the Trustee, the Trustee may conclusively rely, as to the truth of
the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions which by any
provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture; 
  
 (b) the Trustee shall not be liable for any error of
judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be provided that the Trustee was grossly negligent in ascertaining the pertinent facts; 
  
 (c) the Trustee shall not be liable to any Noteholder with respect to any action taken or omitted to be
taken by it in good faith in accordance with the direction of the holders of not less than a majority in principal amount of the Notes at the time outstanding determined as provided in Section 9.4 relating to the time, method and place of conducting
any proceeding for any 
  
  

 -37- 

 remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this
Indenture; and 
  
 (d) whether or not therein
provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section. 
  
 None of the provisions contained in this Indenture shall require the Trustee
to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds
or adequate indemnity against such risk or liability is not reasonably assured to it. 
  
 Section 8.2 Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section 8.1: 
  
 (a) the Trustee may rely and shall be protected in acting upon any resolution, certificate, statement, instrument, opinion, report,
notice, request, consent, order, bond, note, coupon or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties; 
  
 (b) any request, direction, order or demand of the Company
mentioned herein shall be sufficiently evidenced by an Officers’ Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to the Trustee by a copy
thereof certified by the Secretary or an Assistant Secretary of the Company; 
  
 (c) the Trustee may consult with counsel and any advice or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in
accordance with such advice or Opinion of Counsel; 
  
 (d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Noteholders pursuant to the provisions of this Indenture, unless such
Noteholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby; 
  
 (e) the Trustee shall not be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney;
provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably
assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require indemnity reasonably satisfactory to the Trustee from the Noteholders against such expenses or liability as a condition to so proceeding;
the reasonable expenses of every such examination shall be paid by the Company or, if paid by the Trustee or any predecessor Trustee, shall be repaid by the Company upon demand; and 
  
 (f) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either
directly or by or through agents or attorneys and the Trustee shall not be responsible 
  

 -38- 

 for any misconduct or negligence on the part of any agent or attorney appointed by it with due care
hereunder; 
  
 (g) the Trustee shall not be
deemed to have knowledge of any default or Event of Default unless a responsible officer (with direct responsibility for the administration of this Indenture) of the Trustee has actual knowledge thereof or unless written notice of any event which is
in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture; 
  

(h) 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 to each agent, custodian and other Person employed to act hereunder; 
  
 (i) the Trustee shall not be responsible for and makes no representation as to the validity or adequacy of
this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds of the Notes, and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the
sale of the Notes, including any offering document or other disclosure materials, or in the Notes other than the Trustee’s certificate of authentication; 
  

(j) notwithstanding anything else herein contained, whenever any provision of the Indenture indicates that any confirmation of a
condition or event is qualified by the words “actual knowledge of” the Trustee or other words of similar meaning, said words shall mean and refer to the current awareness of one or more Responsible Officers who are located at the Corporate
Trust Office of the Trustee or who are otherwise responsible for administering the trusts created under the Indenture; and 
  
 (k) the Trustee is not required to give any bond or surety with respect to the performance of its duties or the exercise of its powers
under the Indenture. 
  
 In no event shall the Trustee be liable for any
consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action other than through the Trustee’s
willful misconduct or gross negligence. 
  
 Section 8.3 No
Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any
Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. 
  
 Section 8.4 Trustee, Paying Agents, Conversion Agents or Registrar May Own Notes. The Trustee, any paying agent, any conversion agent or Note
registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not Trustee, paying agent, conversion agent or Note registrar. 
  
 Section 8.5 Monies to Be Held in Trust. Subject to the provisions of
Section 13.4, all monies received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from 
  
  
  

 -39- 

 other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as may be agreed from time to time by the Company and the Trustee. 
  
 Section 8.6 Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall
be entitled to, reasonable compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust), and the Company will pay or
reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the
expenses and disbursements of its agents and counsel and of all persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its gross negligence or willful misconduct. The Company also covenants to
indemnify and defend the Trustee in any capacity under this Indenture and its agents and any authenticating agent for, and to hold them harmless against, any loss, liability, claims, damages, causes of action or expense of whatever kind incurred
without gross negligence or willful misconduct on the part of the Trustee or such agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration of this trust or in any other capacity
hereunder, including the costs and expenses of defending themselves against any claim of liability in the premises. The obligations of the Company under this Section 8.6 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for
expenses, disbursements and advances shall be secured by a lien prior to that of the Notes upon all property and funds held or collected by the Trustee as such, except, subject to the effect of Sections 4.3 and 7.6, funds held in trust herewith for
the benefit of the holders of particular Notes prior to the date of the accrual of such unpaid compensation or indemnifiable claim. The obligation of the Company under this Section shall survive the satisfaction and discharge of this Indenture.

  
 When the Trustee and its agents and any authenticating agent
incur expenses or render services after an Event of Default specified in Section 7.1(h) or (i) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or
similar laws. 
  
 Section 8.7 Officers’ Certificate as
Evidence. Except as otherwise provided in Section 8.1, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any
action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of gross negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, be deemed to be
conclusively proved and established by an Officers’ Certificate delivered to the Trustee, and such Officers’ Certificate, in the absence of gross negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, shall
be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof. 
  
 Section 8.8 Conflicting Interests of Trustee. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture
Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. 
  
 Section 8.9 Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a person that is
eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus (together with its corporate parent) of at least $50,000,000. If such person publishes reports of condition at least annually, pursuant to law or to
the requirements of any supervising or examining authority, 
  

 -40- 

 then for the purposes of this Section, the combined capital and surplus of such person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the
effect hereinafter specified in this Article. 
  
 Section 8.10 Resignation or Removal of Trustee. 
  
 (a) The Trustee may at any time resign by giving written notice of such resignation to the Company and by mailing notice thereof to the holders of Notes at their addresses as they shall appear on the Note register. Upon receiving such
notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to
the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment (60) days after the mailing of such notice of resignation to the Noteholders, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee, or any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 7.9, on behalf of himself and all others similarly
situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 
  
 (b) In case at any time any of the following shall occur: 
  
 (1) the Trustee shall fail to comply with Section 8.8 within
a reasonable time after written request therefor by the Company or by any Noteholder who has been a bona fide holder of a Note or Notes for at least six months, or 
  
 (2) the Trustee shall cease to be eligible in accordance with the provisions of Section 8.9 and shall fail
to resign after written request therefor by the Company or by any such Noteholder, or 
  
 (3) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its
property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
  
 then, in any such case, the Company may remove the Trustee and appoint a successor trustee
by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 7.9, any
Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a
successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 
  

(c) The holders of a majority in aggregate principal amount of the Notes at the time outstanding may at any time remove the Trustee and nominate a
successor trustee which shall be deemed appointed as successor trustee unless within ten (10) days after notice to the Company of such nomination the Company objects thereto, in which case the Trustee so removed or any Noteholder, upon the terms and
conditions and otherwise as in Section 8.10(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee. 
  
  
  

 -41- 

 (d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of
the provisions of this Section 8.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.11. 
  
 Section 8.11 Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 8.10 shall execute, acknowledge and deliver to
the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Company or of the successor
trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 8.6, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so
ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing
to act shall, nevertheless, retain a lien upon all property and funds held or collected by such trustee as such, except for funds held in trust for the benefit of holders of particular Notes, to secure any amounts then due it pursuant to the
provisions of Section 8.6. 
  
 No successor trustee shall accept
appointment as provided in this Section 8.11 unless at the time of such acceptance such successor trustee shall be qualified under the provisions of Section 8.8 and be eligible under the provisions of Section 8.9. 
  
 Upon acceptance of appointment by a successor trustee as provided in this
Section 8.11, each of the Company and the former trustee shall mail or cause to be mailed notice of the succession of such trustee hereunder to the holders of Notes at their addresses as they shall appear on the Note register. If the Company fails
to mail such notice within ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 
  
 Section 8.12 Succession by Merger, Etc. Any corporation or other
entity into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity
succeeding to all or substantially all of the trust business of the Trustee, shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that in
the case of any corporation succeeding to all or substantially all of the trust business of the Trustee such corporation shall be qualified under the provisions of Section 8.8 and eligible under the provisions of Section 8.9. 
  
 In case at the time such successor to the Trustee shall succeed to the trusts
created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such
predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate
such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the
certificate of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its
successor or successors by merger, conversion or consolidation.

 ARTICLE IX 
  
 CONCERNING THE NOTEHOLDERS 
  
 Section 9.1 Action by Noteholders. Whenever in this Indenture it is provided that the holders of a specified percentage in aggregate principal
amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the holders of such
specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in writing, or (b) by the record of the holders of Notes
voting in favor thereof at any meeting of Noteholders duly called and held in accordance with the provisions of Article X, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Noteholders. Whenever the
Company or the Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee may fix in advance of such solicitation, a date as the record date for determining holders entitled to take such action. The record date
shall be not more than fifteen (15) days prior to the date of commencement of solicitation of such action. 
  
 Section 9.2 Proof of Execution by Noteholders. Subject to the provisions of Sections 8.1, 8.2 and 10.5, proof of the execution of any instrument by
a Noteholder or his agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be
proved by the Note register or by a certificate of the Note registrar. The record of any Noteholders’ meeting shall be proved in the manner provided in Section 10.6. 
  
 Section 9.3 Who Are Deemed Absolute Owners. The Company, the Trustee, any paying agent, any conversion agent and any
Note registrar may deem the person in whose name such Note shall be registered upon the Note register to be, and may treat him as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of
ownership or other writing thereon) for the purpose of receiving payment of or on account of the principal of, premium, if any, and interest on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the
Trustee nor any paying agent nor any conversion agent nor any Note registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon his order, shall be valid, and, to the extent of the
sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such Note. 
  
 Section 9.4 Company-Owned Notes Disregarded. In determining whether the holders of the requisite aggregate principal amount of Notes have concurred
in any direction, consent, waiver or other action under this Indenture, Notes which are owned by the Company or any other obligor on the Notes or by any person directly or indirectly controlling or controlled by or under direct or indirect common
control with the Company or any other obligor on the Notes shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected
in relying on any such direction, consent, waiver or other action only Notes which a Responsible Officer knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith may be regarded as outstanding for the purposes
of this Section 9.4 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to vote such Notes and that the 
  
  

 -43- 

 pledgee is not the Company, any other obligor on the Notes or a person directly or indirectly controlling or controlled
by or under direct or indirect common control with the Company or any such other obligor. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request
of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described persons; and,
subject to Section 8.1, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such
determination. 
  
 Section 9.5 Revocation of Consents; Future
Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 9.1, of the taking of any action by the holders of the percentage in aggregate principal amount of the Notes specified in this Indenture in
connection with such action, any holder of a Note which is shown by the evidence to be included in the Notes the holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon
proof of holding as provided in Section 9.2, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the holder of any Note shall be conclusive and binding upon such holder and upon all future holders and
owners of such Note and of any Notes issued in exchange or substitution therefor, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor.

Indenture as herein set forth; provided, however, that in respect of any such additional covenant, restriction or condition such supplemental indenture may provide for a particular period of grace after default (which period may be shorter or longer
than that allowed in the case of other defaults) or may provide for an immediate enforcement upon such default or may limit the remedies available to the Trustee upon such default; 
  
 (e) to provide for the issuance under this Indenture of Notes in coupon form (including Notes registrable as

 -46- 

 the Notes issued hereunder in fully registered form and to make all appropriate changes for such purpose;

  
 (f) to cure any ambiguity or to correct or
supplement any provision contained herein or in any supplemental indenture which may be defective or inconsistent with any other provision contained herein or in any supplemental indenture, or to make such other provisions in regard to matters or

further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer and assignment of any property thereunder, but the Trustee shall not be obligated to, but may in its discretion, enter into any

Notes then outstanding.

this Article XI shall comply with the Trust Indenture Act, as then in effect. Upon the execution of any supplemental indenture pursuant to the provisions of this Article XI, this Indenture shall be and be deemed to be modified and amended in
accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the holders of Notes shall thereafter be determined, exercised and enforced hereunder
subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

Certificate and an Opinion of Counsel as required by Section 17.5 and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture; the Company, however, hereby agreeing to

such monies; and the holder of any of the Notes shall thereafter look only to the Company for any payment which such holder may be entitled to collect unless an applicable abandoned property law designates another person. 
  
 Section 13.5 Reinstatement. If (i) the Trustee or the paying agent is

principal amount of the then outstanding Notes so request by written notice to the Trustee, the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 13.1
until such time as the Trustee or the paying agent is permitted to apply all such money in accordance with Section 13.2; provided, however, that if the Company 
  
  
  

 -50- 

 makes any payment of interest on or principal of any Note following the reinstatement of its obligations, the Company

 ARTICLE XIV 
  
 IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS

 ARTICLE XV 
  
 CONVERSION OF NOTES 
  
 Section 15.1 Right to Convert. Subject to and upon compliance with the provisions of this Indenture, the holder of any Note shall have the right,
at his option, at any time following the date of original issuance of the Notes and prior to the close of business on August 15, 2008 (except that, with respect to any Note or portion of a Note which shall be called for redemption, such right shall
terminate at the close of business on the last Business Day prior to the date fixed for redemption of such Note or portion of a Note unless the Company shall default in payment due upon redemption thereof) to convert the principal amount of any such
Note, or any portion of such principal amount which is $1,000 or an integral multiple thereof, into that number of fully paid and non-assessable shares of Common Stock (as such shares shall then be constituted) obtained by dividing the principal
amount of the Note or portion thereof surrendered for conversion by the Conversion Price in effect at such time, by surrender of the Note so to be converted in whole or in part in the manner provided in Section 15.2. A holder of Notes is not
entitled to any rights of a holder of Common Stock until such holder has converted his Notes to Common Stock, and only to the extent such Notes are deemed to have been converted to Common Stock under this Article XV. A Note with respect to which a
holder has delivered a notice in accordance with Section 16.2 regarding such holder’s election to require the Company to repurchase such holder’s Notes following the occurrence of a Change in Control may be converted in accordance with
this Article XV only if such holder withdraws such notice by delivering a written notice of withdrawal to the Company prior to the close of business on last Business Day prior to the day fixed for repurchase. 
  
 Section 15.2 Exercise of Conversion Privilege; Issuance of Common Stock on
Conversion; No Adjustment for Interest or Dividends. In order to exercise the conversion privilege with respect to any Note in definitive form, the holder of any such Note to be converted in whole or in part shall surrender such Note, duly
endorsed, at an office or agency maintained by the Company pursuant to Section 5.2, accompanied by the funds, if any, required by the penultimate paragraph of this Section 15.2, and shall give written notice of conversion in the form provided on the
Notes (or such other notice which is acceptable to the Company) to the office or agency that the holder elects to convert such Note or such portion thereof 
  
  
  

 -51- 

 specified in said notice. Such notice shall also state the name or names (with address) in which the certificate or
certificates for shares of Common Stock which shall be issuable on such conversion shall be issued, and shall be accompanied by transfer taxes, if required pursuant to Section 15.7. Each such Note surrendered for conversion shall, unless the shares
issuable on conversion are to be issued in the same name as the registration of such Note, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the holder or his duly authorized
attorney. 
  
 In order to exercise the conversion privilege with
respect to any interest in a Note in global form, the beneficial holder must complete the appropriate instruction form for conversion pursuant to the Depositary’s book-entry conversion program, deliver by book-entry delivery an interest in such
Note in global form, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or conversion agent, and pay the funds, if any, required by the penultimate paragraph of this Section 15.2 and any transfer taxes,
if required pursuant to Section 15.7. 
  
 As promptly as
practicable after satisfaction of the requirements for conversion set forth above, subject to compliance with any restrictions on transfer if shares issuable on conversion are to be issued in a name other than that of the Noteholder (as if such
transfer were a transfer of the Note or Notes (or portion thereof) so converted), the Company shall issue and shall deliver to such holder at the office or agency maintained by the Company for such purpose pursuant to Section 5.2, a certificate or
certificates for the number of full shares of Common Stock issuable upon the conversion of such Note or portion thereof in accordance with the provisions of this Article and a check or cash in respect of any fractional interest in respect of a share
of Common Stock arising upon such conversion, as provided in Section 15.3 and, if applicable, any cash payment required pursuant to the proviso to the first sentence of Section 15.1 (which payment, if any, shall be paid no later than five Business
Days after satisfaction of the requirements for conversion set forth above). In case any Note of a denomination greater than $1,000 shall be surrendered for partial conversion, and subject to Section 2.3, the Company shall execute and the Trustee
shall authenticate and deliver to the holder of the Note so surrendered, without charge to him, a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note. 
  
 Each conversion shall be deemed to have been effected as to any such Note (or
portion thereof) on the date on which the requirements set forth above in this Section 15.2 have been satisfied as to such Note (or portion thereof), and the person in whose name any certificate or certificates for shares of Common Stock shall be
issuable upon such conversion shall be deemed to have become on said date the holder of record of the shares represented thereby; provided, however, that any such surrender on any date when the stock transfer books of the Company shall
be closed shall constitute the person in whose name the certificates are to be issued as the record holder thereof for all purposes on the next succeeding day on which such stock transfer books are open, but such conversion shall be at the
Conversion Price in effect on the date upon which such Note shall be surrendered. 
  
 Any Note or portion thereof surrendered for conversion during the period from the close of business on the record date for any interest payment date through the close of business on the Business Day next preceding
such interest payment date shall be accompanied by payment, in New York Clearing House funds or other funds acceptable to the Company, of an amount equal to the interest otherwise payable on such interest payment date on the principal amount being
converted; provided, however, that no such payment need be made if there shall exist at the time of conversion a default in the payment of interest on the Notes. Except as provided above in this Section 15.2, no adjustment shall be
made for interest accrued on any Note converted or for dividends on any shares issued upon the conversion of such Note as provided in this Article. 
  
  
  

 -52- 

 Upon the conversion of an interest in a Note in global form, the Trustee, or the Custodian at the
direction of the Trustee, shall make a notation on such Note in global form as to the reduction in the principal amount represented thereby. 
  
 Section 15.3 Cash Payments in Lieu of Fractional Shares. No fractional shares of Common Stock or scrip representing fractional shares shall be
issued upon conversion of Notes. If more than one Note shall be surrendered for conversion at one time by the same holder, the number of full shares which shall be issuable upon conversion shall be computed on the basis of the aggregate principal
amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered for conversion. If any fractional share of stock otherwise would be issuable upon the conversion of any Note or Notes, the Company shall make an
adjustment therefor in cash at the current market value thereof to the holder of Notes. The current market value of a share of Common Stock shall be the Closing Price on the first Trading Day immediately preceding the day on which the Notes (or
specified portions thereof) are deemed to have been converted and such Closing Price shall be determined as provided in Section 15.5(h). 
  
 Section 15.4 Conversion Price. The conversion price per share of Common Stock issuable upon conversion of the Notes (as such price may be adjusted,
herein called the “Conversion Price”) shall initially be $6.6944 (which reflects a conversion rate of 149.3786 shares of Common Stock per $1,000 in principal amount of Notes). 
  
 Section 15.5 Adjustment of Conversion Price. The Conversion Price shall be adjusted from time to time by the Company
as follows: 
  
 (a) In case the Company shall
hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Price in effect at the opening of business on the date following the date fixed for the determination of
stockholders entitled to receive such dividend or other distribution shall be reduced by multiplying such Conversion Price by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the
Record Date) fixed for such determination and the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such reduction to become effective immediately after the opening
of business on the day following the Record Date. If any dividend or distribution of the type described in this Section 15.5(a) is declared but not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would
then be in effect if such dividend or distribution had not been declared. 
  
 (b) In case the Company shall issue short-term rights or warrants to all holders of its outstanding shares of Common Stock entitling them (for a period expiring within forty-five (45) days after the date fixed for the
determination of stockholders entitled to receive such rights or warrants) to subscribe for or purchase shares of Common Stock at a price per share less than the Current Market Price) on the Record Date fixed for the determination of stockholders
entitled to receive such rights or warrants, the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect at the opening of business on the date after such Record Date by a
fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the Record Date plus the number of shares which the aggregate offering price of the total number of shares so offered for
subscription or purchase would purchase at such Current Market Price, and of which the denominator shall be the number of shares of Common Stock outstanding on the close of business on the Record Date plus the total number of additional shares of
Common Stock so offered for subscription or purchase. Such adjustment shall become effective immediately after the opening of business 
  

 -53- 

 on the day following the Record Date fixed for determination of stockholders entitled to receive such
rights or warrants. To the extent that shares of Common Stock are not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or warrants the Conversion Price shall be readjusted to the Conversion Price which
would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. In the event that such rights or warrants are not so
issued, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining
whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into
account any consideration received for such rights or warrants, the value of such consideration, if other than cash, to be determined by the Board of Directors. 
  

(c) In case the outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion
Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller
number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased, such reduction or increase, as the case may
be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. 
  
 (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital
stock of the Company (other than any dividends or distributions to which Section 15.5(a) applies) or evidences of its indebtedness, cash or other assets (including securities, but excluding (1) any rights or warrants referred to in Section 15.5(b)
and, (2) dividends and distributions (A) in connection with the liquidation, dissolution or winding up of the Company or paid (B) exclusively in cash and (3) excluding any capital stock, evidences of indebtedness, cash or assets distributed upon a
merger or consolidation to which Section 15.6 applies) (the foregoing hereinafter in this Section 15.5(d) called the “Securities”)), (unless the Company elects to reserve such Securities for distribution to the Noteholders upon conversion
of the Notes so that any such holder converting Notes will receive upon such conversion, in addition to the shares of Common Stock to which such holder is entitled, the amount and kind of such Securities which such holder would have received if such
holder had converted its Notes into Common Stock immediately prior to the Record Date for such distribution of the Securities) then, in each such case, the Conversion Price shall be reduced so that the same shall be equal to the price determined by
multiplying the Conversion Price in effect immediately prior to the close of business on the Record Date) with respect to such distribution by a fraction of which the numerator shall be the Current Market Price) on such date less the fair market
value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) on such date of the portion of the Securities so distributed applicable to one share of Common Stock and the denominator
shall be such Current Market Price, such reduction to become effective immediately prior to the opening of business on the day following the Record Date; provided, however, that in the event the then fair market value (as so
determined) of the portion of the Securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so
that each Noteholder shall have the right to receive upon conversion of a 
  
  

 -54- 

 Note (or any portion thereof) the amount of Securities such holder would have received had such holder
converted such Note (or portion thereof) immediately prior to such Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in
effect if such dividend or distribution had not been declared. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 15.5(d) by reference to the actual or when issued trading market for any
securities comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the “Reference Period’) used in computing the Current Market Price pursuant to Section 15.5(h) to the
extent possible, unless the Board of Directors in a board resolution determines in good faith that determining the fair market value during the Reference Period would not be in the best interest of the Noteholder. 
  
 Rights or warrants distributed by the Company to all holders
of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events
(“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for
purposes of this Section 15.5(d) (and no adjustment to the Conversion Price under this Section 15.5(d) will be required) until the occurrence of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the
occurrence of which such right or warrant shall become exercisable to purchase different securities, evidences of indebtedness or other assets or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the
foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and record date with respect to a new right or warrant (and a termination or expiration of the existing right or warrant
without exercise by the holder thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto, that
resulted in an adjustment to the Conversion Price under this Section 15.5(d), (1) in the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price 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 such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants all of
which shall have expired or been terminated without exercise, the Conversion Price shall be readjusted as if such rights and warrants had never been issued. 
  
 For purposes of this Section 15.5(d) and Sections 15.5(a) and (b), any dividend or distribution to which this Section 15.5(d) is
applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock to which Section 15.5(b) applies (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences
of indebtedness, assets, shares of capital stock, rights or warrants other than such shares of Common Stock or rights or warrants to which Section 15.5(b) applies (and any Conversion Price reduction required by this Section 15.5(d) with respect to
such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Price reduction required by Sections 15.5(a) and (b) with
respect to such dividend or distribution shall then be made, except (A) the Record Date of such dividend or distribution shall be substituted as “the date fixed for the determination of 
  
  
  

 -55- 

 stockholders entitled to receive such dividend or other distribution”, “Record Date fixed for
such determination” and “Record Date” within the meaning of Section 15.5(a) and as “the date fixed for the determination of stockholders entitled to receive such rights or warrants”, “the Record Date fixed for the
determination of the stockholders entitled to receive such rights or warrants” and “such Record Date” within the meaning of Section 15.5(b) and (B) any shares of Common Stock included in such dividend or distribution shall not be
deemed “outstanding at the close of business on the date fixed for such determination” within the meaning of Section 15.5(a). 
  
 (e) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding any cash that is
distributed upon a merger or consolidation to which Section 15.6 applies or as part of a distribution referred to in Section 15.5(d)), then, and in each such case, immediately after the close of business on such date, the Conversion Price shall be
reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on such Record Date by a fraction (i) the numerator of which shall be equal to the Current Market
Price on the Record Date less an amount equal to the quotient of (x) the amount of such distribution or dividend and (y) the number of shares of Common Stock outstanding on the Record Date and (ii) the denominator of which shall be equal to the
Current Market Price on such date, provided, however, that in the event the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Common Stock on the Record Date, in
lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive upon conversion of a Note (or any portion thereof) the amount of cash such holder would have received had such holder
converted such Note (or portion thereof) immediately prior to such Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in
effect if such dividend or distribution had not been declared. Any cash distribution to all holders of Common Stock as to which the Company makes the election permitted by Section 15.5(n) and as to which the Company has complied with the
requirements of such Section shall be treated as not having been made for all purposes of this Section 15.5(e). 
  
 (f) In case a tender offer made by the Company or any of its subsidiaries for all or any portion of the Common Stock shall expire and such
tender offer (as amended upon the expiration thereof) shall require the payment to stockholders (based on the acceptance (up to any maximum specified in the terms of the tender offer) of Purchased Shares (as defined below)) of an aggregate
consideration having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) that combined together with the aggregate of the cash plus the fair market value (as
determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution), as of the expiration of such tender offer, of consideration payable in respect of any other tender offers, by the Company or any of
its subsidiaries for all or any portion of the Common Stock expiring within the twelve (12) months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to this Section 15.5(f) has been made exceeds 10.0% of
the product of the Current Market Price (determined as provided in Section 15.5(h)) as of the last time (the “Expiration Time”) tenders could have been made pursuant to such tender offer (as it may be amended) times the number of shares of
Common Stock outstanding (including any tendered shares) on the Expiration Time, then, and in each such case, immediately prior to the opening of business on the day after the date of the Expiration Time, the Conversion Price shall be adjusted so
that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to close of business on the date of the Expiration Time by a fraction of which the numerator shall be the number of shares of Common Stock
outstanding (including any tendered 
  

 -56- 

 shares) on the Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading
Day next succeeding the Expiration Time and the denominator shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the
terms of the tender offer) of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of
shares of Common Stock outstanding (less any Purchased Shares) on the Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, such reduction (if any) to become effective immediately
prior to the opening of business on the day following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any
such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender offer had not been made. If the application of this Section 15.5(f) to any
tender offer would result in an increase in the Conversion Price, no adjustment shall be made for such tender offer under this Section 15.5(f). Any cash distribution to all holders of Common Stock as to which the Company has made the election
permitted by Section 15.5(n) and as to which the Company has complied with the requirements of such Section shall be treated as not having been made for all purposes of this Section 15.5(f). 
  
 (g) In case of a tender or exchange offer made by a person
other than the Company or any Subsidiary for an amount which increases the offeror’s ownership of Common Stock to more than 25% of the Common Stock outstanding and shall involve the payment by such person of consideration per share of Common
Stock having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors at the last time (the “Expiration Time”) tenders or exchanges may
be made pursuant to such tender or exchange offer (as it shall have been amended) that exceeds the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, and in which, as of the Expiration Time the Board of
Directors is not recommending rejection of the offer, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the Expiration Time by a fraction of
which the numerator shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) on the Expiration Time multiplied by the current Market Price of the Common Stock on the Trading Day next succeeding the
Expiration Time and the denominator shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or
exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the “Purchased Shares”) and (y) the product of the number
of shares of Common Stock outstanding (less any Purchased Shares) on the Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, such reduction to become effective immediately prior to
the opening of business on the day following the Expiration Time. In the event that such person is obligated to purchase shares pursuant to any such tender or exchange offer, but such person is permanently prevented by applicable law from effecting
any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender or exchange offer had not been made. Notwithstanding the foregoing, the
adjustment described in this Section 15.5(g) shall not be made if, as of the Expiration Time, the offering documents with respect to such offer disclose a plan or intention to cause the Company to engage in any transaction described in Article XII.

  
  
  

 -57- 

 (h) For purposes of this Section 15.5, the following terms shall have the meaning
indicated: 
  
 (1) “Closing Price” with
respect to any securities on any day shall mean the closing sale price regular way on such day or, in case no such sale takes place on such day, the average of the reported closing bid and asked prices, regular way, in each case on the Nasdaq
National Market or New York Stock Exchange, as applicable, or, if such security is not listed or admitted to trading on such National Market or Exchange, on the principal national security exchange or quotation system on which such security is
quoted or listed or admitted to trading, or, if not quoted or listed or admitted to trading on any national securities exchange or quotation system, the average of the closing bid and asked prices of such security on the over-the-counter market on
the day in question as reported by the National Quotation Bureau Incorporated, or a similar generally accepted reporting service, or if not so available, in such manner as furnished by any New York Stock Exchange member firm selected from time to
time by the Board of Directors for that purpose, or a price determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution. 
  
 (2) “Current Market Price” shall mean the average
of the daily Closing Prices per share of Common Stock for the ten (10) consecutive Trading Days immediately prior to the date in question; provided, however, that (1) if the “ex” date (as hereinafter defined) for any event
(other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 15.5(a), (b), (c), (d), (e), (f) or (g) occurs during such ten (10) consecutive Trading Days, the Closing
Price for each Trading Day prior to the “ex” date for such other event shall be adjusted by multiplying such Closing Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event,
(2) if the “ex” date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 15.5(a), (b), (c), (d), (e), (f) or (g) occurs on or after the
“ex” date for the issuance or distribution requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by multiplying such
Closing Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event, and (3) if the “ex” date for the issuance, distribution requiring such computation is prior to the
day in question, after taking into account any adjustment required pursuant to clause (1) or (2) of this proviso, the Closing Price for each Trading Day on or after such “ex” date shall be adjusted by adding thereto the amount of any cash
and the fair market value (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 15.5(d), (f) or (g), whose determination shall be conclusive and described in a Board Resolution)
of the evidences of indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such “ex” date. For purposes of any computation under Sections
15.5(f) or (g), the Current Market Price of the Common Stock on any date shall be deemed to be the average of the daily Closing Prices per share of Common Stock for such day and the next two succeeding Trading Days; provided, however,
that if the “ex” date for any event (other than the tender offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 15.5(a), (b), (c), (d), (e), (f) and (g) occurs on or after the Expiration
Time for the tender or exchange offer requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the “ex” 
  
  

 -58- 

 date for such other event shall be adjusted by multiplying such Closing Price by the reciprocal of the
fraction by which the Conversion Price is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term “ex” date, (1) when used with respect to any issuance or distribution, means the first date on
which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right to receive such issuance or distribution, (2) when used with respect to any subdivision or
combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and (3) when used with respect to
any tender or exchange offer means the first date on which the Common Stock trades regular way on such exchange or in such market after the Expiration Time of such offer. Notwithstanding the foregoing, whenever successive adjustments to the
Conversion Price are called for pursuant to this Section 15.5, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 15.5 and to avoid unjust or inequitable results as
determined in good faith by the Board of Directors. 
  
 (3) “fair market value” shall mean the amount which a willing buyer would pay a willing seller in an arm’s length transaction. 
  
 (4) “Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of
Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for
determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). 
  
 (5) “Trading Day” shall mean (x) if the applicable security is listed or admitted for trading on
the New York Stock Exchange or another national security exchange, a day on which the New York Stock Exchange or another national security exchange is open for business or (y) if the applicable security is quoted on the Nasdaq National Market, a day
on which trades may be made thereon or (z) if the applicable security is not so listed, admitted for trading or quoted, any day other than a Saturday or Sunday or a day on which banking institutions in the State of New York are authorized or
obligated by law or executive order to close. 
  
 (i) The Company may make such reductions in the Conversion Price, in addition to those required by Sections 15.5(a), (b), (c), (d), (e), (f) and (g), as the Board of Directors considers to be advisable to avoid or diminish any income tax to
holders of Common Stock or rights to purchase Common stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. 
  
 To the extent permitted by applicable law, the Company from
time to time may reduce the Conversion Price by any amount for any period of time if the period is at least twenty (20) days, the reduction is irrevocable during the period and the Board of Directors shall have made a determination that such
reduction would be in the best interests of the Company, which determination shall be conclusive and described in a Board Resolution. Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company shall mail to the holder
of each Note at his last address appearing on the Note register provided for in Section 2.5 a notice of the reduction 
  
  
  

 -59- 

 at least fifteen (15) days prior to the date the reduced Conversion Price takes effect,
and such notice shall state the reduced Conversion Price and the period during which it will be in effect. 
  
 (j) No adjustment in the Conversion Price shall be required unless such adjustment would require an increase or decrease of at least 1% in
such price; provided, however, that any adjustments which by reason of this Section 15.5(j) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article
XV shall be made by the Company and shall be made to the nearest cent or to the nearest one hundredth of a share, as the case may be. No adjustment need be made for a change in the par value or no par value of the Common Stock. 
  
 (k) Whenever the Conversion Price is adjusted as herein
provided, the Company shall promptly file with the Trustee and any conversion agent other than the Trustee an Officers’ Certificate setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts
requiring such adjustment. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Price setting forth the adjusted Conversion Price and the date on which each adjustment becomes effective
and shall mail such notice of such adjustment of the Conversion Price to the holder of each Note at his last address appearing on the Note register provided for in Section 2.5, within twenty (20) days of the effective date of such adjustment.
Failure to deliver such notice shall not effect the legality or validity of any such adjustment. 
  
 (l) In any case in which this Section 15.5 provides that an adjustment shall become effective immediately after a Record Date for an
event, the Company may defer until the occurrence of such event (i) issuing to the holder of any Note converted after such Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by
reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 15.3.

  
 (m) For purposes of this Section 15.5, 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. 
  
 (n) In lieu of making any adjustment to the Conversion Price pursuant to Section 15.5(e), the Company may elect to reserve an amount of
cash for distribution to the holders of the Notes upon the conversion of the Notes so that any such holder converting Notes will receive upon such conversion, in addition to the shares of Common Stock and other items to which such holder is
entitled, the full amount of cash which such holder would have received if such holder had, immediately prior to the Record Date for such distribution of cash, converted its Notes into Common Stock, together with any interest accrued with respect to
such amount, in accordance with this Section 15.5(n). The Company may make such election by providing an Officers’ Certificate to the Trustee to such effect on or prior to the payment date for any such distribution and depositing with the
Trustee on or prior to such date an amount of cash equal to the aggregate amount the holders of the Notes would have received if such holders had, immediately prior to the Record Date for such distribution, converted all of the Notes into Common
Stock. Any such funds so deposited by the Company with the Trustee shall be invested by the Trustee in marketable obligations issued or fully guaranteed by the United States government with a maturity not 
  
  
  

 -60- 

 more than three (3) months from the date of issuance. Upon conversion of Notes by a holder, the holder
will be entitled to receive, in addition to the Common Stock issuable upon conversion, an amount of cash equal to the amount such holder would have received if such holder had, immediately prior to the Record Date for such distribution, converted
its Note into Common Stock, along with such holder’s pro rata share of any accrued interest earned as a consequence of the investment of such funds. Promptly after making an election pursuant to this Section 15.5(n), the Company shall give or
shall cause to be given notice to all Noteholders of such election, which notice shall state the amount of cash per $1,000 principal amount of Notes such holders shall be entitled to receive (excluding interest) upon conversion of the Notes as a
consequence of the Company having made such election. 
  
 Section
15.6 Effect of Reclassification, Consolidation, Merger or Sale. If any of the following events occur, namely (i) any reclassification or change of the outstanding shares of Common Stock (other than a 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, merger or combination of the Company with another corporation as a result of which holders of Common Stock shall be entitled to
receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, or (iii) any sale or conveyance of the properties and assets of the Company as, or substantially as, an entirety to any
other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, then the Company or the successor or
purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such supplemental indenture
is then required to so comply) providing that such Note shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash) receivable upon such reclassification, change, consolidation,
merger, combination, sale or conveyance by a holder of a number of shares of Common Stock issuable upon conversion of such Notes (assuming, for such purposes, a sufficient number of authorized shares of Common Stock available to convert all such
Notes) immediately prior to such reclassification, change, consolidation, merger, combination, sale or conveyance assuming such holder of Common Stock did not exercise his rights of election, if any, as to the kind or amount of securities, cash or
other property receivable upon such consolidation, merger, statutory exchange, sale or conveyance (provided that, if the kind or amount of securities, cash or other property receivable upon such consolidation, merger, statutory exchange, sale or
conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised (“non-electing share”), then for the purposes of this Section 15.6 the kind and amount of securities, cash
or other property receivable upon such consolidation, merger, statutory exchange, sale or conveyance for each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). Provided,
however, the Trustee shall be under no obligation to join with the Company in the execution of such supplemental indenture, if such supplemental indenture adversely affects the Trustee’s own rights, duties or immunities under this Indenture.
Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article. If, in the case of any such reclassification, change, consolidation, merger,
combination, sale or conveyance, the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing
corporation, as the case may be, in such reclassification, change, consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions
to protect the interests of the holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the repurchase rights set forth in
Article XVI herein. 
  
  

 -61- 

 The Company shall cause notice of the execution of such supplemental indenture to be mailed to each
holder of Notes, at his address appearing on the Note register provided for in Section 2.5 of this Indenture, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such
supplemental indenture. 
  
 The above provisions of this Section
shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. 
  
 If this Section 15.6 applies to any event or occurrence, Section 15.5 shall not apply. 
  
 Section 15.7 Taxes on Shares Issued. The issue of stock certificates
on conversions of Notes shall be made without charge to the converting Noteholder for any tax in respect of the issue thereof. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the
issue and delivery of stock in any name other than that of the holder of any Note converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the person or persons requesting the issue thereof
shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 
  
 Section 15.8 Reservation of Shares; Shares to Be Fully Paid; Listing of Common Stock. The Company shall provide, free from preemptive rights, out
of its authorized but unissued shares or shares held in treasury, sufficient shares to provide for the conversion of the Notes from time to time as such Notes are presented for conversion. 
  
 Before taking any action which would cause an adjustment reducing the
Conversion Price below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Notes, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may
validly and legally issue shares of such Common Stock at such adjusted Conversion Price. 
  
 The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof.

  
 The Company further covenants that if at any time the Common
Stock shall be listed on the Nasdaq National Market or any other national securities exchange or automated quotation system the Company will, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as
the Common Stock shall be so listed on such exchange or automated quotation system, all Common Stock issuable upon conversion of the Notes. 
  
 Section 15.9 Responsibility of Trustee. The Trustee and any other conversion agent shall not at any time be under any duty or responsibility to any
holder of Notes to determine whether any facts exist which may require any adjustment of the Conversion Price, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein
or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other conversion agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any
securities or property, which may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other conversion agent make no representations with respect thereto. Subject to the provisions of Section 8.1, neither the
Trustee nor any conversion agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any note for the
purpose of conversion or to comply with any of the duties, responsibilities or covenants of the 
  

 62 

 Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any
conversion agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 15.6 relating either to the kind or amount of shares of stock or securities or
property (including cash) receivable by Noteholders upon the conversion of their Notes after any event referred to in such Section 15.6 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 8.1, may accept
as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental
indenture) with respect thereto. 
  
 Section 15.10 Notice to
Holders Prior to Certain Actions. In case: 
  
 (a) the Company shall declare a dividend (or any other distribution) on its Common Stock (that would require an adjustment in the Conversion Price pursuant to Section 15.5); or 
  
 (b) the Company shall authorize the granting to the holders of its Common Stock of rights or warrants to
subscribe for or purchase any share of any class or any other rights or warrants; or 
  
 (c) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock,
or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of any shareholders of the Company is required, or of the sale
or transfer of all or substantially all of the assets of the Company; or 
  
 (d) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company; 
  
 the Company shall cause to be filed with the Trustee and to be mailed to each holder of Notes at his address appearing on the Note register, provided for in Section 2.5
of this Indenture, as promptly as possible but in any event at least fifteen days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or
rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or (y) the date on which such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock
for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of
such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. 
  
 ARTICLE XVI 
  
 REPURCHASE UPON A CHANGE IN CONTROL 
  
 Section 16.1 Repurchase Right. If, at any time prior to August 15, 2008 there shall occur a Change in Control, then each Noteholder shall have the right, at such holder’s option, to require the Company to
repurchase all of such holder’s Notes, or any portion thereof (in principal amounts of $1,000 or integral multiples thereof), on the repurchase date that is forty (40) days after the date of the Company Notice of such Change in Control (or, if
such 40th day is not a Business Day, the next succeeding Business Day). Such repayment shall be made in cash at a price equal to 100% of the principal amount of 
  

 

 -63- 

 Notes such holder elects to require the Company to repurchase (the “Repurchase Price”); provided that if such
repurchase date is February 15 or August 15, then the interest payable on such date shall be paid to the holder of record of the Note on the next preceding February 1 or August 1, respectively. In each case, the Company shall also pay to such
holders accrued interest to the repurchase date on the redeemed Notes. No Notes may be redeemed at the option of holders upon a Change in Control if there has occurred and is continuing an Event of Default, other than a default in the payment of the
Repurchase Price with respect to such Notes on the repurchase date. 
  
 Section 16.2 Notices; Method of Exercising Repurchase Right, Etc. 
  
 (a) Unless the Company shall have theretofore called for redemption all of the outstanding Notes, on or before the fifteenth (15th)
calendar day after the occurrence of a Change in Control, the Company or, at the written request and expense of the Company, the Trustee, shall mail to all holders a notice (the “Company Notice”) of the occurrence of the Change in Control
and of the repurchase right set forth herein arising as a result thereof. The Company shall also deliver a copy of such notice of a repurchase right to the Trustee and cause a copy of such notice of a repurchase right, or a summary of the
information contained therein, to be published in a newspaper of general circulation in The City of New York. The Company shall incur all out-of-pocket expenses of such delivery and publication. The Company Notice shall contain the following
information: 
  
 (1) the repurchase date,

  
 (2) the date by which the repurchase right
must be exercised, 
  
 (3) the last date by which
the election to require repurchase, if submitted, must be revoked; 
  
 (4) the Repurchase Price, 
  
 (5) a description of the procedure which a holder must follow to exercise a repurchase right, and 
  
 (6) the Conversion Price then in effect, the date on which the right to convert the principal amount of the Notes to be repurchased will
terminate and the place or places where Notes may be surrendered for conversion. 
  
 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 Notes. 
  
 If any of the foregoing provisions are inconsistent with applicable law, such law shall govern. 
  
 (b) To exercise a repurchase right, a holder shall deliver to the Trustee on or before the thirty-fifth (35th) day after the Company
Notice (i) written notice to the Company (or agent designated by the Company for such purpose) of the holder’s exercise of such right, which notice shall set forth the name of the holder, the principal amount of the Notes to be repurchased, a
statement that an election to exercise the repurchase right is being made thereby, and (ii) the Notes with respect to which the repurchase right is being exercised, duly endorsed for transfer to the Company. Election of repurchase by a holder shall
be revocable at any time prior to, but excluding, the repurchase date, by delivering written notice to that effect to the Trustee prior to the close of business on the Business Day prior to the repurchase date. 
  
  

 -64- 

 (c) If the Company fails to repurchase on the repurchase date any Notes (or portions
thereof) as to which the repurchase right has been properly exercised, then the principal of such Notes shall, until paid, bear interest to the extent permitted by applicable law from the repurchase date at the rate borne by the Note and each such
Note shall be convertible into Common Stock in accordance with this Indenture (without giving effect to Section 16.2(b)) until the principal of such Note shall have been paid or duly provided for. 
  
 (d) Any Note which 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 his attorney duly
authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the holder of such Note without service charge, a new Note or Notes, containing identical terms and conditions, of any authorized denomination
as requested by such holder in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Note so surrendered. 
  
 (e) On or prior to the repurchase date, the Company shall deposit with the Trustee or with a paying agent (or, if the Company is acting as
its own paying agent, segregate and hold in trust as provided in Section 5.4) an amount of money sufficient to pay the Repurchase Price of the Notes that are to be repaid on the repurchase date, provided that if such payment is made on the
repurchase date it must be received by the Trustee or paying agent, as the case may be, by 10:00 a.m., New York City time, on such date. 
  
 Section 16.3 Conditions to the Company’s Election to Pay the Repurchase Price in Common Stock. The Company may elect to pay all or a portion
of the Repurchase Price by delivery of shares of Common Stock pursuant to Section 16.1 if and only if the following conditions shall have been satisfied: 
  
 (a) The shares of Common Stock deliverable in payment of the Repurchase Price shall have a fair market value as of the repurchase date of
not less than the Repurchase Price. For purposes of Section 16.1 and this Section 16.3, the fair market value of shares of Common Stock shall be determined by the Company and shall be equal to 95% of the average of the Closing Prices of the Common
Stock for the five consecutive Trading Days immediately preceding the second Trading Day prior to the repurchase date; 
  
 (b) The Repurchase Price shall be paid only in cash in the event any shares of Common Stock to be issued upon repurchase of Notes
hereunder (i) require registration under any federal securities law before such shares may be freely transferable without being subject to any transfer restrictions under the Securities Act upon repurchase and if such registration is not completed
or does not become effective prior to the repurchase date, and/or (ii) require registration with or approval of any governmental authority under any state law or any other federal law before such shares may be validly issued or delivered upon
repurchase and if such registration is not completed or does not become effective or such approval is not obtained prior to the repurchase date; 
  
 (c) Payment of the Repurchase Price may not be made in Common Stock unless such stock is, or shall have been, approved for quotation on
the Nasdaq National Market or listed on a national securities exchange, in either case, prior to the repurchase date; and 
  
 (d) All shares of Common Stock which may be issued upon repurchase of the Notes will be issued out of the Company’s authorized but
unissued Common Stock and, will upon issue, be duly and validly issued and fully paid and non- assessable and free of any preemptive rights. 
  

 -65- 

 If all of the conditions set forth in this Section 16.3 are not satisfied in accordance with the terms
thereof, the Repurchase Price shall be paid by the Company only in cash. In the event the Company elects to pay only a portion of the Repurchase Price in Common Stock, the Company shall pay the remaining balance of the Repurchase Price in cash.

  
 Section 16.4 Certain Definitions. For
purposes of this Article XVI:

 (c) the term “Continuing Director” means at any
date a member of the Company’s Board of Directors (i) who was a member of such board on August 7, 2003 or (ii) who was nominated or elected by at least a majority of the directors who were Continuing Directors at the time of such nomination or
election or whose election to the Company’s Board of Directors was recommended or endorsed by at least a majority of the directors who were Continuing Directors at the time of such nomination or election or such lesser number comprising a
majority of a nominating committee whose authority and composition have been approved by at least a majority of the directors who were continuing directors at the time such committee was formed. (Under this definition, if the current Board of
Directors of the Company were to approve a new director or directors and then resign, no Change in Control would occur even though the current Board of Directors would thereafter cease to be in office). 
  
 (d) a “Change in Control” shall be deemed to have
occurred when (i) any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act) is or becomes the “beneficial owner” (as defined in Rules 13-d3 and 13-d5 under the Exchange Act) of
shares representing more than 50% of the combined voting power of the then outstanding securities entitled to vote generally in elections of directors of the Company (the “Voting Stock”); (ii) stockholders of the Company approve any plan

transaction, or (B) conveys, transfers or leases all or substantially all of its assets to any person; or (iv) any time Continuing Directors do not constitute a majority of the Board of Directors of the Company (or, if applicable, a successor
corporation to the Company); provided that a Change in Control shall not be deemed to have occurred if either (x) the Closing Price of the Common Stock for any five (5) Trading Days during the ten (10) Trading Days immediately preceding the Change
in Control is at least equal to 105% of the Conversion Price in effect on the date on which the Change in Control occurs or (y) in the case of a merger or consolidation, all of the consideration (excluding cash payments for fractional shares) in the
transaction or transactions constituting the Change in Control consists of common stock or securities convertible into common stock that are, or upon issuance will be, traded on a United States national 
  

 -66- 

 securities exchange or quoted on the Nasdaq National Market (or which will be so traded or quoted when
issued or exchanged in connection with such Change in Control) and as a result of such transaction or transactions such Notes become convertible solely into such common stock.

 REVERSE OF NOTE 
  

  
 5% Convertible Subordinated Note due 2008 
  
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 5% Convertible Subordinated Notes due 2008 (herein called the “Notes”), limited to the aggregate principal amount of $85,000,000 all issued or
to be issued under and pursuant to an Indenture dated as of August 12, 2003 (herein called the “Indenture”), between the Company and SunTrust Bank (herein called the “Trustee”), to which Indenture and all indentures supplemental
thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders of the Notes. 
  
 In case an Event of Default, as defined in the Indenture, shall have occurred
and be continuing, the principal of and accrued interest on all Notes may be declared, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture. 
  
 The Indenture contains provisions permitting the Company and the Trustee in
certain limited circumstances, without the consent of the holders of the Notes, and in other circumstances, with the consent of the holders of not less than a majority of the aggregate principal amount of the Notes at the time outstanding, evidenced
as in the Indenture provided, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the
holders of the Notes; provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of any Note, or reduce the rate or extend the time of payment of interest thereon, or reduce the principal amount thereof or premium, if
any, thereon, or reduce any amount payable on repurchase thereof, impair, or change in any respect adverse to the holder of Notes, the obligation of the Company to repurchase any Note at the option of the holder upon the happening of a Change in
Control, or impair or adversely affect the right of any Noteholder to institute suit for the payment thereof, or make the principal thereof or interest or premium, if any, thereon payable in any coin or currency other than that provided in the
Notes, or modify the provisions of the Indenture with respect to the subordination of the Notes in a manner adverse to the Noteholders, or impair, or change in any respect adverse to the holders of the Notes, the right to convert the Notes into
Common Stock subject to the terms set forth in the Indenture, including Section 15.6 thereof, without the consent of the holder of each Note so affected or (ii) reduce the aforesaid percentage of Notes, the holders of which are required to consent
to any such supplemental indenture, without the consent of the holders of all Notes then outstanding. It is also provided in the Indenture that, prior to any declaration accelerating the maturity of the Notes, the holders of a majority in aggregate
principal amount of the Notes at the time outstanding may on behalf of the holders of all of the Notes waive any past default or Event of Default under the Indenture and its consequences except a default in the payment of interest or any premium on
or the principal of or any redemption price or repurchase price of any of the Notes or a failure by the Company to convert any Notes into Common Stock of the Company. Any such consent or waiver by the holder of this Note (unless revoked as provided
in the Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution hereof, irrespective of whether or not any notation thereof is made
upon this Note or such other Notes. 
  
 The indebtedness evidenced
by the Notes is, to the extent and in the manner provided in the Indenture, expressly subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness of the Company, as defined in the Indenture, whether
outstanding at the date of the Indenture 
  
  

 -6- 

 or thereafter incurred, and this Note is issued subject to the provisions of the Indenture with respect to such
subordination. Each holder of this Note, by accepting the same, agrees to and shall be bound by such provisions and authorizes the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination so
provided and appoints the Trustee his attorney in fact for such purpose. 
  
 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium
and interest on this Note at the place, at the respective times, at the rate and in the coin or currency herein prescribed. 
  
 Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months compounded semi-annually. The Company will not be
required to make any payment on the Notes due on any day which is not a Business Day until the next succeeding Business Day. The payment made on the next succeeding Business Day will be treated as though it were paid on the original due date and no
interest will accrue on the payment for the additional period of time. 
  
 The Notes are issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to
the limitations provided in the Indenture, without payment of any service charge but with payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration or exchange of Notes, Notes
may be exchanged for a like aggregate principal amount of Notes of other authorized denominations. 
  
 The Company may redeem some or all of the Notes at any time at a redemption price of $1,000 per $1,000 principal amount of Notes, plus accrued and unpaid
interest, if any, to the redemption date, plus the Interest Make-Whole Payment; provided that the closing price of the Common Stock on the Nasdaq National Market has exceeded 150% of the Conversion Price then in effect for at least 20 Trading Days
within a period of 30 consecutive Trading Says ending on the Trading Day immediately before the date of mailing of the provision redemption notice and (2) the registration statement covering the Notes and the Common Stock issuable upon conversion of
the Notes is effective and available for use for the 30 days following the provisional redemption date, unless registration is not required. 
  
 The Company will pay holders any accrued and unpaid interest through the date of redemption as well as the Interest Make-Whole Payment on the Notes called
for redemption, regardless of whether those Notes are converted prior to the date of the redemption. 
  
 The Interest Make-Whole Payment will be payable in cash or, at our option, subject to certain conditions, in Common Stock or a combination thereof. The
number of shares of Common Stock will equal the amount of the Interest Make-Whole Payment being paid in Common Stock divided by 95% of the average closing sale price for the five consecutive Trading Days ending on and including the third day prior
to the date of the redemption. 
  
 Notice of any redemption will
be sent, by first class mail, at least 30 days and not more than 60 days prior to the date fixed for redemption (the “redemption date”), to the holder of each Note to be redeemed to such holder’s last address as then shown upon the
registry books of the registrar. The notice of redemption must state the redemption date, the redemption price, the amount of accrued interest, if any, to be paid and the Interest Make-Whole Payment. Any notice that relates to a Note to be redeemed
in part only must state the portion of the principal amount to be redeemed and must state that on and after the redemption date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion thereof will be
issued. On and after the redemption date, interest will cease to accrue 
  
  

 -7- 

 on the Notes or portions thereof called for redemption, unless the Company defaults in its obligations with respect
thereto. 
  
 The Notes are not subject to
redemption through the operation of any sinking fund. 
  
 Upon the
occurrence of a “Change in Control”, the Noteholder has the right, at such holder’s option, to require the Company to repurchase all or any portion of such holder’s Notes on the 40th day after notice of such Change in Control at
a price equal to 100% of the principal amount of the Notes, together in each case with accrued interest to the date fixed for redemption; provided that if such repurchase date is February 15 or August 15, then the interest payable on such date shall
be paid to the holder of record of the Note on the next preceding February 1 or August 1, respectively. The Company shall mail to all holders of record of the Notes a notice of the occurrence of a Change in Control and of the repurchase right
arising as a result thereof on or before 15 calendar days after the occurrence of such Change in Control. Payment of all or a portion of the repurchase price may be made in shares of the Company’s Common Stock under certain circumstances, as
provided in Section 16.3 of the Indenture. 
  
 Subject to the
provisions of the Indenture, the holder hereof has the right, at its option, at any time following the date of original issuance of the Notes and prior to the close of business on August 15, 2008, or, as to all or any portion hereof called for
redemption, prior to the close of business on the Business Day next preceding the date fixed for redemption (unless the Company shall default in payment due upon redemption), to convert the principal hereof or any portion of such principal which is
$1,000 or an integral multiple thereof, into that number of fully paid and non-assessable shares of Company’s Common Stock, as said shares shall be constituted at the date of conversion, obtained by dividing the principal amount of this Note or
portion thereof to be converted by the Conversion Price, upon surrender of this Note, together with a conversion notice as provided in the Indenture and this Note, to the Company at the office or agency of the Company maintained for that purpose in
the Borough of Manhattan, The City of New York, or at the option of such holder, the Corporate Trust Office, and, unless the shares issuable on conversion are to be issued in the same name as this Note, duly endorsed by, or accompanied by
instruments of transfer in form satisfactory to the Company duly executed by, the holder or by his duly authorized attorney. No adjustment in respect of interest or dividends will be made upon any conversion; provided, however, that if
this Note shall be surrendered for conversion during the period from the close of business on any record date for the payment of interest through the close of business on the Business Day next preceding the following interest payment date, this Note
must be accompanied by an amount, in funds acceptable to the Company, equal to the interest otherwise payable on such interest payment date on the principal amount being converted. No fractional shares of Common Stock will be issued upon any
conversion, but an adjustment in cash will be paid to the holder, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Note or Notes for conversion. 
  
 Any Notes called for redemption, unless surrendered for conversion, may be
deemed to be purchased from the holder of such Notes at an amount equal to the applicable redemption price, together with accrued interest to and including the date fixed for redemption, and the Interest Make-Whole Payment, by one or more investment
bankers or other purchasers who may agree with the Company to purchase such Notes from the holders thereof and convert them into Common Stock of the Company and to make payment for such Notes as aforesaid to the Trustee in trust for such holders.

  
 Upon due presentment for registration of transfer of this Note
at the office or agency of the Company in the Borough of Manhattan, The City of New York, or at the option of the holder of this Note, at the Corporate Trust Office, a new Note or Notes of authorized denominations for an equal aggregate principal
amount will be issued to the transferee in exchange thereof, subject to the limitations provided in the 
  
  

 -8- 

 Indenture, without charge except for any tax or other governmental charge imposed in connection therewith. 
  
 The Company, the Trustee, any authenticating agent, any paying agent, any
conversion agent and any Note registrar may deem and treat the registered holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon made by
anyone other than the Company or any Note registrar), for the purpose of receiving payment hereof, or on account hereof, for the conversion hereof and for all other purposes, and neither the Company nor the Trustee nor any other authenticating agent
nor any paying agent nor any other conversion agent nor any Note registrar shall be affected by any notice to the contrary. All payments made to or upon the order of such registered holder shall, to the extent of the sum or sums paid, satisfy and
discharge liability for monies payable on this Note. 
  
 No
recourse for the payment of the principal of or any premium or interest on this Note, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture
or any indenture supplemental thereto or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer, director or subsidiary, as such, past, present or
future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or
otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released. 
  
 Terms used in this Note and defined in the Indenture are used herein as therein defined.
