 2.
Exchange Offer. 
  
 (a) Unless the Exchange Offer would
violate applicable law or any applicable interpretation of the staff of the SEC, the Issuers shall use their best efforts to file with the SEC, no later than the Filing Date, a Registration Statement (the “Exchange Offer Registration
Statement”) on an appropriate registration form with respect to a registered offer (the “Exchange Offer”) to exchange any and all of the Registrable Notes for a like aggregate principal amount of debt securities
of the Company (the “Exchange Notes”) guaranteed by the Guarantors that are identical in all material respects to the Securities, except that (i) the Exchange Notes shall contain no restrictive legend thereon and (ii) the
Exchange Notes shall not be entitled to any of the rights set forth in Section 4 of this Agreement, and that are entitled to the benefits of the Indenture, which shall be qualified under the TIA. The Exchange Offer shall comply with all applicable
tender offer rules and regulations under the Exchange Act and other applicable laws. The Issuers shall (x) use their reasonable best efforts to cause the Exchange Offer Registration Statement to be declared effective under the Securities Act on or
before the Effectiveness Date; (y) keep the Exchange Offer open for at least 30 days (or longer if required by applicable law) after the date that notice of the Exchange Offer is mailed to Holders; and (z) consummate the Exchange Offer on or prior
to the 180th day following the Issue Date. 
  
 The parties hereto
acknowledge that each Holder (including, without limitation, each Participating Broker-Dealer) who participates in the Exchange Offer will be required to represent to the Issuers in writing (which may be contained in the applicable letter of
transmittal) that: (i) any Exchange Notes acquired in exchange for Registrable Notes tendered are being acquired in the ordinary course of business of the Person receiving such Exchange Notes, whether or not such recipient is such Holder itself;
(ii) at the time of the commencement or consummation of the Exchange Offer neither such Holder nor, to the actual knowledge of such Holder, any other Person receiving Exchange Notes from such Holder has an arrangement or understanding with any
Person to participate in the distribution of the Exchange Notes in violation of the provisions of the Securities Act; (iii) neither the Holder nor, to the actual knowledge of such Holder, any other Person receiving Exchange Notes from 
  

 -5- 








 such Holder is an “affiliate” (as defined in Rule 405) of the Company or, if it is an affiliate of the Company,
it will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable and will provide information to be included in the Shelf Registration Statement in accordance with Section 5 hereof in order to
have their Notes included in the Shelf Registration Statement and benefit from the provisions regarding Additional Interest in Section 4 hereof; (iv) neither such Holder nor, to the actual knowledge of such Holder, any other Person receiving
Exchange Notes from such Holder is engaging in or intends to engage in a distribution of the Exchange Notes; and (v) if such Holder is a Participating Broker-Dealer, such Holder has acquired the Registrable Notes as a result of market-making
activities or other trading activities and that it will comply with the applicable provisions of the Securities Act (including, but not limited to, the prospectus delivery requirements thereunder). 
  
 Upon consummation of the Exchange Offer in accordance with this Section 2,
the provisions of this Agreement shall continue to apply solely with respect to Registrable Notes that are Private Exchange Notes, Exchange Notes as to which Section 2(c)(iv) is applicable and Exchange Notes held by Participating Broker-Dealers, and
the Issuers shall have no further obligation to register Registrable Notes (other than Private Exchange Notes and Exchange Notes as to which clause 2(c)(iv) hereof applies) pursuant to Section 3 hereof. 
  
 No securities other than the Exchange Notes shall be included in the Exchange
Offer Registration Statement. 
  
 (b) The Issuers shall include
within the Prospectus contained in the Exchange Offer Registration Statement a section entitled “Plan of Distribution,” reasonably acceptable to the Initial Purchasers, which shall contain a summary statement of the positions taken or
policies made by the staff of the SEC with respect to the potential “underwriter” status of any broker-dealer that is the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act) of Exchange Notes received by such
broker-dealer in the Exchange Offer (a “Participating Broker-Dealer”). Such “Plan of Distribution” section shall also expressly permit, to the extent permitted by applicable policies and regulations of the SEC, the
use of the Prospectus by all Persons subject to the prospectus delivery requirements of the Securities Act, including, to the extent permitted by applicable policies and regulations of the SEC, all Participating Broker-Dealers, and include a
statement describing the means by which Participating Broker-Dealers may resell the Exchange Notes in compliance with the Securities Act. 
  
 The Issuers shall use their reasonable best efforts to keep the Exchange Offer Registration Statement effective and to amend and supplement the Prospectus
contained therein in order to permit such Prospectus to be lawfully delivered by all Persons subject to the prospectus delivery requirements of the Securities Act for such period of time as is necessary to comply with applicable law in connection
with any resale of the Exchange Notes; provided, however, that such period shall not be required to exceed 90 days or such longer period if extended pursuant to the last paragraph of Section 5 hereof (the “Applicable
Period”). 
  

 -6- 








 If, prior to consummation of the Exchange Offer, the Initial Purchasers hold any Notes acquired by them
that have the status of an unsold allotment in the initial distribution, the Issuers upon the request of the Initial Purchasers shall simultaneously with the delivery of the Exchange Notes issue and deliver to the Initial Purchasers, in exchange
(the “Private Exchange”) for such Notes held by any such Holder, a like principal amount of notes (the “Private Exchange Notes”) of the Issuers, guaranteed by the Guarantors that are identical in all
material respects to the Exchange Notes except for the placement of a restrictive legend on such Private Exchange Notes. The Private Exchange Notes shall be issued pursuant to the same indenture as the Exchange Notes and bear the same CUSIP number
as the Exchange Notes. 
  
 In addition to the provisions set forth
elsewhere in this Section 2, in connection with the Exchange Offer, the Issuers shall: 
  
 (1) mail, or cause to be mailed, to each Holder of record entitled to participate in the Exchange Offer a copy of the Prospectus forming
part of the Exchange Offer Registration Statement, together with an appropriate letter of transmittal and related documents; 
  
 (2) utilize the services of a depositary for the Exchange Offer with an address in the Borough of Manhattan, The City of New York; and

  
 (3) permit Holders to withdraw tendered
Securities at any time prior to the close of business, New York time, on the last Business Day on which the Exchange Offer remains open. 
  
 As soon as practicable after the close of the Exchange Offer and the Private Exchange, if any, the Issuers shall: 
  
 (1) accept for exchange all Registrable Notes validly
tendered and not validly withdrawn pursuant to the Exchange Offer or the Private Exchange, if any; 
  
 (2) cause the Exchange Agent to deliver to the Trustee for cancellation all Registrable Notes so accepted for exchange; and 
  
 (3) cause the Trustee to authenticate and deliver promptly
to each Holder of Securities, Exchange Notes or Private Exchange Notes, as the case may be, equal in principal amount to the Securities of such Holder so accepted for exchange; provided that, in the case of any Securities held in global form
by a depositary, authentication and delivery to such depositary of one or more replacement Securities in global form in an equivalent principal amount thereto for the account of such Holders in accordance with the Indenture shall satisfy such
authentication and delivery requirement. 
  

 -7- 








 The Exchange Offer and the Private Exchange shall not be subject to any conditions, other than that (i)
the Exchange Offer or Private Exchange or the making of any exchange by a Holder, as the case may be, does not violate applicable law or any applicable interpretation of the staff of the SEC; (ii) no action or proceeding shall have been instituted
or threatened in any court or by any governmental agency with respect to the Exchange Offer or the Private Exchange which might materially impair the ability of the Issuers to proceed with the Exchange Offer or the Private Exchange, (iii) no
material adverse development shall have occurred in any existing action or proceeding with respect to the Issuers; (iv) all governmental approvals shall have been obtained, which approvals the Issuers deem necessary for the consummation of the
Exchange Offer or Private Exchange; (v) the due tendering of Registrable Notes shall be in accordance with the Exchange Offer or Private Exchange; and (vi) each Holder of Registrable Securities exchanged in the Exchange Offer shall have made all of
the representations required to be made pursuant to Section 2(a) of this Agreement. 
  
 The Exchange Notes and the Private Exchange Notes shall be issued under (i) the Indenture or (ii) an indenture identical in all material respects to the Indenture and which, in either case, has been qualified under
the TIA or is exempt from such qualification and shall provide that the Exchange Notes shall not be subject to the transfer restrictions set forth in the Indenture. 
  
 (c) If, (i) because of any change in law or in currently prevailing interpretations of the staff of the SEC, the Issuers are
not permitted to effect the Exchange Offer, (ii) the Exchange Offer is not consummated within 180 days of the Issue Date, (iii) the Initial Purchasers or any holder of Private Exchange Notes so requests in writing to the Company at any time after
the consummation of the Exchange Offer, or (iv) in the case of any Holder that participates in the Exchange Offer, such Holder does not receive Exchange Notes on the date of the exchange that may be sold without restriction under state and federal
securities laws (other than due solely to the status of such Holder as an affiliate of the Issuers within the meaning of the Securities Act) and so notifies the Company within 30 days after such Holder first becomes aware of such restrictions, in
the case of each of clauses (i) to and including (iv) of this sentence, then the Issuers shall promptly deliver to the Holders and the Trustee written notice thereof (the “Shelf Notice”) and shall file a Shelf Registration
pursuant to Section 3 hereof. 
  

 -8- 








 3. Shelf Registration 
  
 If a Shelf Notice is delivered as contemplated by Section 2(c) hereof, then: 
  
 (a) Shelf Registration. The Issuers shall as
promptly as practicable file with the SEC a Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 covering all of the Registrable Notes (the “Shelf Registration”). The Issuers shall use
their reasonable best efforts to file with the SEC the Shelf Registration on or prior to the applicable Filing Date. The Shelf Registration shall be on Form S-1 or another appropriate form permitting registration of such Registrable Notes for resale
by Holders in the manner or manners designated by Holders of a majority of the aggregate principal amount of such Registrable Notes participating in the Shelf Registration (including, without limitation, one or more underwritten offerings). The
Issuers shall not permit any securities other than the Registrable Notes and the Guarantees to be included in the Shelf Registration. 
  
 The Issuers shall use their reasonable best efforts to cause the Shelf Registration to be declared effective under the Securities Act on
or prior to the Effectiveness Date and to keep the Shelf Registration continuously effective under the Securities Act until the date that is two years from the Issue Date or such shorter period ending when all Registrable Notes covered by the Shelf
Registration have been sold or cease to be outstanding in the manner set forth and as contemplated in the Shelf Registration (the “Effectiveness Period”); provided, however, that the Effectiveness Period in
respect of the Shelf Registration shall be extended to the extent required to permit dealers to comply with the applicable prospectus delivery requirements of Rule 174 under the Securities Act and as otherwise provided herein and shall be subject to
reduction to the extent that the applicable provisions of Rule 144(k) are amended or revised to reduce the two year holding period set forth therein. 
  
 (b) Withdrawal of Stop Orders. If the 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 Notes registered thereunder), the Issuers shall use their reasonable best efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event
shall within 30 days of such cessation of effectiveness amend such Shelf Registration Statement in a manner to obtain the withdrawal of the order suspending the effectiveness thereof. 
  
 (c) Supplements and Amendments. The Issuers 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 a majority in aggregate
principal amount of the Registrable Notes (or their counsel) covered by such Registration Statement with respect to the information included therein with respect to one or more of such Holders, or by any underwriter of such Registrable Notes with
respect to the information included therein with respect to such underwriter. 
  

 -9- 








 4. Additional Interest 
  
 (a) The Issuers and the Initial Purchasers agree that the Holders will suffer damages if the Issuers fail to fulfill their
obligations under Section 2 or Section 3 hereof and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Issuers agree that, as liquidated damages, the interest rate on the Notes will increase
(“Additional Interest”) under the circumstances and to the extent set forth below (each of which shall be given independent effect): 
  
 (i) if (A) neither the Exchange Offer Registration Statement nor the Shelf Registration has been filed on or prior to the Filing Date
applicable thereto or (B) notwithstanding that the Issuers have consummated or will consummate the Exchange Offer, the Issuers are required to file a Shelf Registration and such Shelf Registration is not filed on or prior to the Filing Date
applicable thereto, then, commencing on the day after any such Filing Date, Additional Interest shall accrue on the principal amount of the Notes at a rate of 0.25% per annum for the first 90 days immediately following such applicable Filing Date,
and such Additional Interest rate shall increase by an additional 0.25% per annum at the beginning of each subsequent 90-day period; or 
  
 (ii) if (A) neither the Exchange Offer Registration Statement nor the Shelf Registration is declared effective by the SEC on or prior to
the Effectiveness Date applicable thereto or (B) notwithstanding that the Issuers have consummated or will consummate the Exchange Offer, the Issuers are required to file a Shelf Registration and such Shelf Registration is not declared effective by
the SEC on or prior to the Effectiveness Date applicable to such Shelf Registration, then, commencing on the day after such Effectiveness Date, Additional Interest shall accrue on the principal amount of the Notes at a rate of 0.25% per annum for
the first 90 days immediately following the day after such Effectiveness Date, and such Additional Interest rate shall increase by an additional 0.25% per annum at the beginning of each subsequent 90-day period; or 
  
 (iii) if (A) the Issuers have not exchanged Exchange Notes
for all Notes validly tendered in accordance with the terms of the Exchange Offer on or prior to the 181st day after the Issue Date or (B) if applicable, a Shelf Registration has been declared effective and such Shelf Registration ceases to be
usable by the Holders for any reason for 30 days in the aggregate in any consecutive twelve-month period during the Effectiveness Period, then Additional Interest shall accrue on the principal amount of the Notes at a rate of 0.25% per annum for the
first 90 days commencing on the (x) 181st day after the Issue Date, in the case of (A) above, or (y) the day such Shelf Registration ceases to be effective in the case of (B) above, and such Additional Interest rate shall increase by an additional
0.25% per annum at the beginning of each such subsequent 90-day period; 
  

 -10- 








 provided, however, that (1) the Additional Interest rate on the Notes may not accrue under more than one of
the foregoing clauses (i)-(iii) at any one time and at no time shall the aggregate amount of additional interest accruing exceed in the aggregate 1.0% per annum; provided, further, however, that (1) upon the filing of the
applicable Exchange Offer Registration Statement or the applicable Shelf Registration as required hereunder (in the case of clause (i) above of this Section 4), (2) upon the effectiveness of the Exchange Offer Registration Statement or the
applicable Shelf Registration Statement as required hereunder (in the case of clause (ii) of this Section 4), or (3) upon the exchange of the Exchange Notes for all Notes tendered (in the case of clause (iii)(A) of this Section 4), or upon the
effectiveness of the applicable Shelf Registration Statement which had ceased to remain effective (in the case of (iii)(B) of this Section 4), Additional Interest on the Notes in respect of which such events relate as a result of such clause (or the
relevant subclause thereof), as the case may be, shall cease to accrue. 
  
 (b) The Issuers shall notify the Trustee within three Business Days after each and every date on which an event occurs in respect of which Additional Interest is required to be paid (an “Event Date”). Any amounts of
Additional Interest due pursuant to clause (a) of this Section 4 will be payable in cash semiannually on each April 1 and October 1 (to the holders of record on the March 15 and September 15 immediately preceding such dates), commencing with the
first such date occurring after any such Additional Interest commences to accrue. The amount of Additional Interest will be determined by multiplying the applicable Additional Interest rate by the principal amount of the Registrable Notes,
multiplied by a fraction, the numerator of which is the number of days such Additional Interest 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. No Additional Interest shall accrue with respect to Notes that are not Registrable Notes. 
  
 5. Registration Procedures. 
  
 In connection with the filing of any Registration Statement pursuant to Section 2 or 3 hereof, the Issuers shall effect such
registrations to permit the sale 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 Issuers hereunder, each
of the Issuers shall: 
  
 (a) Prepare and file
with the SEC prior to the applicable Filing Date a Registration Statement or Registration Statements as prescribed by Section 2 or 3 hereof, 
  

 -11- 








 and use its reasonable best efforts to cause each such Registration Statement to become effective and
remain effective as provided herein and, before filing any Registration Statement or Prospectus or any amendments or supplements thereto, the Issuers shall furnish to and afford the Initial Purchasers and the Holders of the Registrable Notes to be
named in such Registration Statement or each such Participating Broker-Dealer, as the case may be, their counsel and the managing underwriters, if any, a reasonable opportunity to review copies of all such documents (including copies of any
documents to be incorporated by reference therein and all exhibits thereto) proposed to be filed (in each case at least five Business Days prior to such filing). The Issuers shall not file any Registration Statement or Prospectus or any amendments
or supplements thereto if the Initial Purchasers or the Holders of a majority in aggregate principal amount of the Registrable Notes to be named in such Registration Statement, their counsel, or the managing underwriters, if any, shall reasonably
object within five (5) Business Days. 
  
 (b)
Prepare and file with the SEC such amendments and post-effective amendments to each Shelf Registration Statement or Exchange Offer Registration Statement, as the case may be, as may be necessary to keep such Registration Statement continuously
effective for the Effectiveness Period, the Applicable Period or until consummation of the Exchange Offer, as the case may be; 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, if required; and comply with the provisions of the Securities 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 and with respect to the subsequent resale of any securities being sold by an Participating Broker-Dealer covered by any such Prospectus. 
  
 (c) Notify the Initial Purchasers, the selling Holders of Registrable Notes to be named in any Registration
Statement or each such Participating Broker-Dealer, as the case may be, their counsel and the managing underwriters, if any, promptly (but in any event within two Business Days) in writing, (i) when a Registration Statement has been filed and has
become effective under the Securities Act, (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 prospectus or the initiation of any
proceedings for that purpose, (iii) of the receipt by any Issuer of any notification with respect to the suspension of the qualification or exemption from qualification of a Registration Statement or any of the Registrable Notes or the Exchange
Notes for offer or sale in any jurisdiction, or the initiation or threatening of any proceeding for such purpose, (iv) 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 any document incorporated therein by reference untrue in any material respect or that requires the making of any changes in or amendments or supplements 
  

 -12- 








 to such Registration Statement or documents so that the Registration Statement 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 (v) of the Issuers’ determination that a post-effective amendment to a
Registration Statement would be appropriate. 
  
 (d) Use its 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 or suspending the qualification (or exemption
from qualification) of any of the Registrable Notes or the Exchange Notes, for sale in any jurisdiction, and, if any such order is issued, to use its reasonable best efforts to obtain the withdrawal of any such order at the earliest practicable
moment. 
  
 (e) If a Shelf Registration is filed
pursuant to Section 3 and if requested during the Effectiveness Period by the managing underwriter or underwriters (if any), the Holders of a majority in aggregate principal amount of the Registrable Notes being sold in connection with an
underwritten offering or any Participating Broker-Dealer, (i) as promptly as practicable incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter or underwriters (if any), such Holders, any
Participating Broker-Dealer or counsel for any of them reasonably request to be included therein and (ii) make all required filings of any supplement or amendment as soon as practicable after the Company has received notification of the matters to
be incorporated in such supplement or amendment. 
  
 (f) Furnish to each selling Holder of Registrable Notes to be named in any Registration Statement and to each such Participating Broker-Dealer who so requests and to their respective counsel and each managing underwriter, if any, at the
sole expense of the Issuers, one conformed copy of the Registration Statement or Registration Statements, including financial statements and schedules, and, if requested, all documents incorporated or deemed to be incorporated therein by reference
and all exhibits and as many copies of the Prospectus or Prospectuses (including each form of preliminary prospectus) and any documents incorporated by reference therein as such Persons may reasonably request; and, subject to the last paragraph of
this Section 5, the Issuers hereby consent to the use of such Prospectus by each of the selling Holders of Registrable Notes named therein or each such Participating Broker-Dealer, as the case may be, and the underwriters or agents, if any, and
dealers, if any, in connection with the offering and sale of the Registrable Notes covered by, or the sale by Participating Broker-Dealers of the Exchange Notes pursuant to, such Prospectus. 
  
 (g) Prior to any public offering of Registrable Notes or any
delivery of a Prospectus contained in the Exchange Offer Registration Statement, cooperate with the selling Holders of Registrable Notes to be named in the Registration Statement or 
  

 -13- 








 each such Participating Broker-Dealer, as the case may be, 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 Notes for offer and sale under the securities or Blue Sky laws of such jurisdictions
within the United States as Holders of a majority of the aggregate principal amount being registered thereby, Participating Broker-Dealer, or the managing underwriter or underwriters reasonably request in writing; provided, however,
that no Issuer shall 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. 
  
 (h) Cooperate with the selling Holders of Registrable Notes and the managing underwriter or underwriters, if any, to facilitate the timely
preparation and delivery of certificates representing Registrable Notes 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 Registrable
Notes to be in such denominations (subject to applicable requirements contained in the Indenture) and registered in such names as the managing underwriter or underwriters, if any, or Holders may request. 
  
 (i) Use its reasonable best efforts to cause the Registrable
Notes covered by the Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the seller or sellers thereof or the underwriter or underwriters, if any, to consummate
the disposition of such Registrable Notes, except as may be required solely as a consequence of the nature of such selling Holder’s business, in which case the Issuers will cooperate in all respects with the filing of such Registration
Statement and the granting of such approvals. 
  
 (j) Upon the occurrence of any event contemplated by paragraph 5(c)(v) or 5(c)(vi) hereof, as promptly as practicable prepare and (subject to Section 5(a) hereof) file with the SEC, at the sole expense of the Issuers, a supplement or
post-effective amendment to the Registration Statement or any document incorporated or deemed to be incorporated therein by reference, or file any other required document so that 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. 
  
 (k) Use its reasonable best efforts to cause the Registrable
Notes covered by a Registration Statement or the Exchange Notes, as the case may be, to be rated 
  

 -14- 








 with the appropriate rating agencies (unless such Notes are already so rated), if so requested by the
Holders of a majority in aggregate principal amount of Registrable Notes covered by such Registration Statement or the Exchange Notes, as the case may be, or the managing underwriter or underwriters, if any. 
  
 (l) Prior to the effective date of the first Registration
Statement relating to the Registrable Notes, (i) provide the Trustee with certificates for the Registrable Notes in a form eligible for deposit with The Depository Trust Company and (ii) provide a CUSIP number for the Registrable Notes. 

 
 (m) In connection with any underwritten offering of
Registrable Notes pursuant to a Shelf Registration, enter into an underwriting agreement as is customary in underwritten offerings of debt securities similar to the 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 Notes and, in such connection, (i) make such representations and warranties to, and covenants with, the underwriters with
respect to the business of the Issuers (including any acquired business, properties 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 debt securities similar to the Securities, and confirm the same in writing if and when requested; (ii) obtain the written opinions of counsel to the Issuers, and
written updates thereof in form, scope and substance reasonably satisfactory to the managing underwriter or underwriters, addressed to the underwriters covering the matters customarily covered in opinions reasonably requested in underwritten
offerings; (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 Issuers (and, if
necessary, any other independent certified public accountants of the Issuers, or of any business acquired by the Issuers, 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 debt
securities similar to the Securities; and (iv) if an underwriting agreement is entered into, the same shall contain indemnification provisions and procedures no less favorable to the sellers and underwriters, if any, than those set forth in Section
7 hereof (or such other provisions and procedures reasonably acceptable to Holders of a majority in aggregate principal amount of Registrable Notes covered by such Registration Statement and the managing underwriter or underwriters or agents, if
any) with respect to all parties to be indemnified pursuant thereto. The above shall be done at each closing under such underwriting agreement, or as, and to the extent, required thereunder. 
  

 -15- 








 (n) Make available for inspection by any Initial Purchaser, any selling Holder of such
Registrable Notes being named in any Registration Statement or each such Participating Broker-Dealer, as the case may be, any underwriter participating in any such disposition of Registrable Notes, if any, and any attorney, accountant or other agent
retained by any such selling Holder or each such Participating Broker-Dealer (with respect to any such Registration Statement), as the case may be, or underwriter (any such Initial Purchaser, Holders, Participating Broker-Dealers, underwriters,
attorneys, accountants or agents, collectively, the “Inspectors”), upon written request, at the offices where normally kept, during reasonable business hours, all pertinent financial and other records, pertinent corporate
documents and instruments of the Issuers and subsidiaries of the Company (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 Issuers and any of their respective subsidiaries, if any, to supply all information (“Information”) reasonably requested by any such Inspector in connection with such due diligence
responsibilities. Each Inspector shall agree in writing that it will keep the Records and Information confidential and that it will not disclose any of the Records or Information unless (i) the disclosure of such Records or Information is necessary
to avoid or correct a misstatement or omission in such Registration Statement or Prospectus, (ii) the release of such Records or Information is ordered pursuant to a subpoena or other order from a court of competent jurisdiction, (iii) disclosure of
such Records or Information is necessary or advisable, in the opinion of counsel for any Inspector, in connection with any action, claim, suit or proceeding, directly or indirectly, involving or potentially involving such Inspector and arising out
of, based upon, relating to, or involving this Agreement or the Purchase Agreement, or any transactions contemplated hereby or thereby or arising hereunder or thereunder, or (iv) the information in such Records or Information has been made generally
available to the public other than through disclosure by an Inspector or an “affiliate” (as defined in Rule 405) thereof; provided, however, that prior notice shall be provided as soon as practicable to any Issuer of the
potential disclosure of any information by such Inspector pursuant to clause (i), (ii) or (iii) of this sentence to permit the Issuers to undertake appropriate action to prevent disclosure of such Records or Information at the Issuers’ expense.

  
 (o) Cause the Indenture to be qualified under
the TIA not later than the effective date of the first Registration Statement required by this Agreement and, in connection therewith, cooperate with the trustee under the Indenture and the Holders of the Registrable Notes, to effect such changes
(if any) to the Indenture as may be required for such indenture to be so qualified in accordance with the terms of the TIA; and execute, and use its reasonable best efforts to cause such 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 such indenture to be so qualified in a timely manner. 
  

 -16- 








 (p) Comply with all applicable rules and regulations of the SEC and make generally
available to its securityholders with regard to any applicable Registration Statement, a consolidated earnings statement satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under
the Securities Act) no later than 45 days after the end of any fiscal quarter (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 Notes 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) Upon consummation of the Exchange Offer or a Private Exchange, or if so requested by the Trustee, obtain an opinion of counsel to the Issuers, in a form customary for underwritten transactions, addressed to the
Trustee for the benefit of all Holders of Registrable Notes participating in the Exchange Offer or the Private Exchange, as the case may be, that the Exchange Notes or Private Exchange Notes, as the case may be, the related guarantees and the
Indenture constitute legal, valid and binding obligations of the Issuers, enforceable against the Issuers in accordance with their respective terms, subject to customary exceptions and qualifications. If the Exchange Offer or a Private Exchange is
to be consummated, upon delivery of the Registrable Notes by Holders to the Company (or to such other Person as directed by the Company), in exchange for the Exchange Notes or the Private Exchange Notes, as the case may be, the Issuers shall mark,
or cause to be marked, on such Registrable Notes that such Registrable Notes are being canceled in exchange for the Exchange Notes or the Private Exchange Notes, as the case may be; in no event shall such Registrable Notes be marked as paid or
otherwise satisfied. 
  
 (r) Cooperate with each
Holder of Registrable Notes covered by any Registration Statement and each underwriter, if any, participating in the disposition of such Registrable Notes and their respective counsel in connection with any filings required to be made with the
National Association of Securities Dealers, Inc. (the “NASD”). 
  
 (s) Use its reasonable best efforts to take all other steps necessary to effect the registration of the Exchange Notes and/or Registrable
Notes covered by a Registration Statement contemplated hereby. 
  
 The Issuers may require each Holder of Registrable Notes as to which any registration is being effected to furnish to the Issuers such information regarding such Holder and the distribution of such Registrable Notes as the Issuers may, from
time to time, reasonably request. The Issuers may exclude from such registration the Registrable Notes of any Holder 
  

 -17- 








 so long as such Holder fails to furnish such information within a reasonable time after receiving such request. Each
Holder as to which any Shelf Registration is being effected agrees to furnish promptly to the Issuers all information required to be disclosed in order to make the information previously furnished to the Issuers by such Holder not materially
misleading. 
  
 If any such Registration Statement refers to any
Holder by name or otherwise as the holder of any securities of the Company, then such Holder shall have the right to require (i) the insertion therein of language, in form and substance reasonably satisfactory to such Holder, to the effect that the
holding by such Holder of such securities is not to be construed as a recommendation by such Holder of the investment quality of the securities covered thereby and that such holding does not imply that such Holder will assist in meeting any future
financial requirements of the Company, or (ii) in the event that such reference to such Holder by name or otherwise is not required by the Securities Act or any similar federal statute then in force, the deletion of the reference to such Holder in
any amendment or supplement to the Registration Statement filed or prepared subsequent to the time that such reference ceases to be required. 
  
 Each Holder of Registrable Notes and each Participating Broker-Dealer agrees by its acquisition of such Registrable Notes or Exchange Notes to be sold by
such Participating Broker-Dealer, as the case may be, that, upon actual receipt of any notice from the Company (i) of the happening of any event of the kind described in Section 5(c)(ii), 5(c)(iv), 5(c)(v), or 5(c)(vi) hereof, such Holder will
forthwith discontinue disposition of such Registrable Notes covered by such Registration Statement or Exchange Notes to be sold by such Holder or Participating Broker-Dealer, as the case may be, until such Holder’s or Participating
Broker-Dealer’s receipt of the copies of any supplemented or amended Prospectus contemplated by Section 5(k) hereof, or until it is advised in writing (the “Advice”) by the Issuers that the use of the applicable
Prospectus may be resumed, and has received copies of any amendments or supplements thereto. In the event that the Issuers shall give any such notice, each of the Applicable Period and the Effectiveness Period shall be extended by the number of days
during such periods from and including the date of the giving of such notice to and including the date when each seller of Registrable Notes covered by such Registration Statement or Exchange Notes, as the case may be, shall have received (x) the
copies of the supplemented or amended Prospectus contemplated by Section 5(k) hereof or (y) the Advice. 
  
 6. Registration Expenses. 
  
 All fees and expenses incident to the performance of or compliance with this Agreement by the Issuers (other than any underwriting discounts or
commissions) shall be borne by the Issuers, whether or not the Exchange Offer Registration Statement or any Shelf Registration Statement is filed or becomes effective or the Exchange Offer is consummated, including, without limitation, (i) all
registration and filing fees (including, without limitation, 
  

 -18- 








 (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), (ii) printing expenses, including, without limitation, expenses of printing certificates for Registrable Notes or Exchange Notes in a form eligible for deposit with The
Depository Trust Company and of printing prospectuses, (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel for, and other Persons retained by, the Issuers and, in the case of a Shelf Registration, reasonable fees
and disbursements of one special counsel for all of the sellers of Registrable Notes, (v) fees and disbursements of all independent certified public accountants referred to in Section 5(o)(iii) hereof (including, without limitation, the expenses of
any “cold comfort” letters required by or incident to such performance), (vi) internal expenses of the Issuers (including, without limitation, all salaries and expenses of officers and employees of the Issuers performing legal or
accounting duties), (vii) the expense of any annual audit and (viii) any fees and expenses incurred in connection with the listing of the securities to be registered on any securities exchange, and the obtaining of a rating of the securities, in
each case, if applicable. 
  
 7. Indemnification and
Contribution. 
  
 (a) Each of the Issuers agree, jointly
and severally, to indemnify and hold harmless each Holder of Registrable Notes and each Participating Broker-Dealer selling Exchange Notes during the Applicable Period, and each Person, if any, who controls such Person or its affiliates within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, a “Participant”) against any losses, claims, damages or liabilities to which any Participant may become subject under the Act, the Exchange Act or
otherwise, insofar as any such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon: 
  
 (i) any untrue statement or alleged untrue statement made by any Issuer contained in any application or any other document or any
amendment or supplement thereto executed by any Issuer based upon written information furnished by or on behalf of any Issuer filed in any jurisdiction in order to qualify the Notes under the securities or Blue Sky laws thereof or filed with the SEC
or any securities association or securities exchange (each, an “Application”); 
  
 (ii) any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement (or any amendment
thereto) or Prospectus (as amended or supplemented if any of the Issuers shall have furnished any amendments or supplements thereto) or any preliminary prospectus; or 
  
 (iii) the omission or alleged omission to state, in any Registration Statement (or any amendment thereto) or
Prospectus (as amended or supplemented if the Issuers 
  

 -19- 








 shall have furnished any amendments or supplements thereto) or any preliminary prospectus or any
Application or any other document or any amendment or supplement thereto, a material fact required to be stated therein or necessary to make the statements therein not misleading; 
  
 and will reimburse, as incurred, the Participant for any reasonable legal or other expenses incurred by the Participant in connection with
investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action; provided, however, the Issuers will not be liable in any such case (i) to the extent that any
such loss, claim, damage, or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in any Registration Statement or any preliminary prospectus or Application or any amendment
or supplement thereto in reliance upon and in conformity with information relating to any Participant furnished to the Issuers by such Participant specifically for use therein and (ii) if such Participant sold to the person asserting the claim the
Registrable Notes or Exchange Notes that are the subject of such claim and such untrue statement or alleged untrue statement or omission or alleged omission was contained or made in any preliminary prospectus and corrected in the Prospectus or any
amendment or supplement thereto and the Prospectus does not contain any other untrue statement or omission of a material fact that was the subject matter of the related proceeding and it is established by the Issuers in the related proceeding that
such Participant failed to deliver or provide a copy of the Prospectus (as amended or supplemented) to such Person with or prior to the confirmation of the sale of such Registrable Notes or Exchange Notes sold to such Person if required by
applicable law, unless such failure to deliver or provide a copy of the Prospectus (as amended or supplemented) was a result of noncompliance with the Issuers with Section 7 of this Agreement. The indemnity provided for in this Section 7 will be in
addition to any liability that the Issuers may otherwise have to the indemnified parties. The Issuers shall not be liable under this Section 7 for any settlement of any claim or action effected without its prior written consent, which shall not be
unreasonably withheld. 
  
 (b) Each Participant, severally and not
jointly, agrees to indemnify and hold harmless the Issuers, their directors, their officers and each Person, if any, who controls the Issuers within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims,
damages or liabilities to which the Issuers or any such director, officer or controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any Application, Registration Statement or Prospectus, any amendment or supplement thereto, or any preliminary prospectus, or (ii)
the omission or the alleged omission to state therein a material fact necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in reliance upon and in conformity with written information concerning such Participant, furnished to the Issuers by the Participant, 
  

 -20- 








 specifically for use therein; and subject to the limitation set forth immediately preceding this clause, will reimburse,
as incurred, any legal or other expenses incurred by the Issuers or any such director, officer or controlling person in connection with investigating or defending against or appearing as a third party witness in connection with any such loss, claim,
damage, liability or action in respect thereof. The indemnity provided for in this Section 7 will be in addition to any liability that the Participants may otherwise have to the indemnified parties. The Participants shall not be liable under this
Section 7 for any settlement of any claim or action effected without their consent, which shall not be unreasonably withheld. The Issuers shall not, without the prior written consent of such Participant, effect any settlement or compromise of any
pending or threatened proceeding in respect of which any Participant is or could have been a party, or indemnity could have been sought hereunder by any Participant, unless such settlement (A) includes an unconditional written release of the
Participants, in form and substance reasonably satisfactory to the Participants, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure
to act by or on behalf of any Participant. 
  
 (c) Promptly after
receipt by an indemnified party under this Section 7 of notice of the commencement of any action for which such indemnified party is entitled to indemnification under this Section 7, such indemnified party will, if a claim in respect thereof is to
be made against the indemnifying party under this Section 7, notify the indemnifying party of the commencement thereof in writing; but the omission to so notify the indemnifying party (i) will not relieve it from any liability under paragraph (a) or
(b) above unless and to the extent such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party
other than the indemnification obligation provided in paragraphs (a) and (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided,
however, that if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the defendants in any such action include both the indemnified party and
the indemnifying party and the indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the
indemnifying party, or (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after receipt by the indemnifying party of notice of the
institution of such action, then, in each such case, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to
select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense 
  

 -21- 








 thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will
not be liable to such indemnified party under this Section 7 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the
indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the
expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated by
Participants who sold a majority in interest of the Registrable Notes and Exchange Notes sold by all such Participants in the case of paragraph (a) of this Section 7 or the Issuers in the case of paragraph (b) of this Section 7, representing the
indemnified parties under such paragraph (a) or paragraph (b), as the case may be, who are parties to such action or actions) or (ii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense
of the indemnifying party. All fees and expenses reimbursed pursuant to this paragraph (c) shall be reimbursed as they are incurred. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable
for the costs and expenses of any settlement of such action effected by such indemnified party without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld), unless such indemnified party waived in
writing its rights under this Section 7, in which case the indemnified party may effect such a settlement without such consent. 
  
 (d) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 7 is unavailable to, or insufficient to
hold harmless, an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), each indemnifying party, in order to provide for just and equitable contribution, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or parties on
the one hand and the indemnified party on the other from the offering of the Notes or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the
indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in
respect thereof). The relative benefits received by the Issuers on the one hand and such Participant on the other shall be deemed to be in the same proportion as the total proceeds from the offering (before deducting expenses) of the Notes received
by the Issuers bear to the total net profit received by such Participant in connection with the sale of the Notes. 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 Issuers on the one hand, 
  

 -22- 








 or the Participants on the other, the parties’ relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission or alleged statement or omission, and any other equitable considerations appropriate in the circumstances. The parties agree that it would not be equitable if the amount of such contribution were
determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (d). Notwithstanding any other provision of this
paragraph (d), no Participant shall be obligated to make contributions hereunder that in the aggregate exceed the total net profit received by such Participant in connection with the sale of the Notes, less the aggregate amount of any damages that
such Participant has otherwise been required to pay by reason of the untrue or alleged untrue statements or the omissions or alleged omissions to state a material fact, and no person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph (d), each person, if any, who controls a Participant within the meaning of Section 15
of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Participants, and each director of any Issuer, each officer of any Issuer and each person, if any, who controls any Issuer within the meaning of Section
15 of the Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Issuers. 
  
 8. Rules 144 and 144A. 
  
 For so long as the Registrable Notes remain outstanding, each of the Issuers covenants and agrees that it will file the reports required to be filed by it
under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder in a timely manner in accordance with the requirements of the Securities Act and the Exchange Act and, if at any time such Issuer is not
required to file such reports, such Issuer will, upon the request of any Holder or beneficial owner of Registrable Notes, make available such information necessary to permit sales pursuant to Rule 144A. Each of the Issuers further covenants and
agrees, for so long as any Registrable Notes remain outstanding that it will take such further action as any Holder of Registrable Notes may reasonably request, all to the extent required from time to time to enable such holder to sell Registrable
Notes without registration under the Securities Act within the limitation of the exemptions provided by Rule 144(k) under the Securities Act and Rule 144A. 
  
 9. Underwritten Registrations. 
  
 If any of the Registrable Notes covered by any Shelf Registration are to be sold in an underwritten offering, the investment banker or investment bankers
and manager or 
  

 -23- 








 managers that will manage the offering will be selected by the Holders of a majority in aggregate principal amount of
such Registrable Notes included in such offering and shall be reasonably acceptable to the Issuers. 
  
 No Holder of Registrable Notes may participate in any underwritten registration hereunder unless such Holder (a) agrees to sell such Holder’s
Registrable Notes 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 required under the terms of such underwriting arrangements. 
  
 10. Miscellaneous. 
  
 (a) No Inconsistent Agreements. The Issuers have not, as of the date hereof, and the Issuers shall not, after the date of this Agreement, enter into any agreement with respect to any of their securities that is inconsistent
with the rights granted to the Holders of Registrable Notes in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights
granted to the holders of the Issuers’ other issued and outstanding securities under any such agreements. The Issuers will not enter into any agreement with respect to any of their securities which will grant to any Person piggy-back
registration rights with respect to any Registration Statement. 
  
 (b) Adjustments Affecting Registrable Notes. The Issuers shall not, directly or indirectly, take any action with respect to the Registrable Notes as a class that would adversely affect the ability of the Holders of Registrable
Notes to include such Registrable Notes 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 (I) the Company, and (II)(A) the Holders of not less than a majority in aggregate principal amount of the then outstanding Registrable Notes and
(B) in circumstances that would adversely affect the Participating Broker-Dealers, the Participating Broker-Dealers holding not less than a majority in aggregate principal amount of the Exchange Notes held by all Participating Broker-Dealers;
provided, however, that Section 7 and this Section 10(c) may not be amended, modified or supplemented without the prior written consent of each Holder and each Participating Broker-Dealer (including any person who was a Holder or
Participating Broker-Dealer of Registrable Notes or Exchange Notes, as the case may be, disposed of pursuant to any Registration Statement) affected by any such amendment, modification or supplement. Notwithstanding the foregoing, a waiver or
consent to depart from the provisions hereof with respect 
  

 -24- 








 to a matter that relates exclusively to the rights of Holders of Registrable Notes whose securities are being sold
pursuant to a Registration Statement may be given by Holders of at least a majority in aggregate principal amount of the Registrable Notes being sold pursuant to such Registration Statement. 
  
 (d) Notices. All notices and other communications (including,
without limitation, any notices or other communications to the Trustee) provided for or permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, next-day air courier or facsimile: 
  
 (i) if to a Holder of the Registrable Notes or any
Participating Broker-Dealer, at the most current address of such Holder or Participating Broker-Dealer, as the case may be, set forth on the records of the registrar under the Indenture, with a copy in like manner to the Initial Purchasers as
