than 150 days after the Closing Date (or if such 150th day is not a Business Day, the next succeeding Business Day), a Registration 

 

 -3- 








 
Statement under the Securities Act relating to the Exchange Securities and the Exchange Offer, (ii) in connection with the foregoing, (A) file all pre-effective amendments to such
Registration Statement as may be necessary in order to cause such Registration Statement to become effective, (B) if applicable, file a post-effective amendment to such Registration Statement pursuant to Rule 430A under the Securities Act and
(C) cause all necessary filings in connection with the registration and qualification of the Exchange Securities to be made under the state securities or blue sky laws of such jurisdictions as are necessary to Consummate the Exchange Offer, and
(iii) upon the effectiveness of such Registration Statement, commence the Exchange Offer. The Exchange Offer shall be on the appropriate form permitting registration of the Exchange Securities to be offered in exchange for the Transfer
Restricted Securities and to permit resales of Initial Securities held by Broker-Dealers as contemplated by Section 3(c) hereof. 

(b) The Company and the Guarantors shall cause the Exchange Offer Registration Statement to be effective continuously and shall keep the
Exchange Offer open for a period ending on the later of (i) 20 days after the date notice of the Exchange Offer is mailed to the Holders and (ii) the minimum period required under applicable federal and state securities laws to Consummate
the Exchange Offer. The Company shall cause the Exchange Offer to comply with all applicable federal and state securities laws. No securities other than the Exchange Securities shall be included in the Exchange Offer Registration Statement. The
Company shall use its reasonable best efforts to cause the Exchange Offer to be Consummated on the earliest practicable date after the Exchange Offer Registration Statement has become effective, but in no event later than 210 days after the Closing
Date (or if such 210th day is not a Business Day, the next succeeding Business Day). 
 (c) The Company shall indicate in a
“Plan of Distribution” section contained in the Prospectus forming a part of the Exchange Offer Registration Statement that any Broker-Dealer who holds Initial Securities that are Transfer Restricted Securities and that were acquired for
its own account as a result of market-making activities or other trading activities (other than Transfer Restricted Securities acquired directly from the Company), may exchange such Initial Securities pursuant to the Exchange Offer; however, such
Broker-Dealer may be deemed to be an “underwriter” within the meaning of the Securities Act and must, therefore, deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of the Exchange Securities
received by such Broker-Dealer in the Exchange Offer, which prospectus delivery requirement may be satisfied by the delivery by such Broker-Dealer of the Prospectus contained in the Exchange Offer Registration Statement. Such “Plan of
Distribution” section shall also contain all other information with respect to such resales by Broker-Dealers that the Commission may require in order to permit such resales pursuant thereto, but such “Plan of Distribution” shall not
name any such Broker-Dealer or disclose the amount of Initial Securities held by any such Broker-Dealer except to the extent required by the Commission as a result of a change in policy after the date of this Agreement. 

Each of the Company and the Guarantors shall use its reasonable best efforts to keep the Exchange Offer Registration Statement
continuously effective, supplemented and amended as required by the provisions of Section 6(c) hereof to the extent necessary to ensure that it is available for resales of Initial Securities acquired by Broker-Dealers for their own accounts as
a result of market-making activities or other trading activities, and to ensure that it conforms with the 
  

 -4- 








 
requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period ending on the earlier of (i) 180
days from the date on which the Exchange Offer Registration Statement is declared effective and (ii) the date on which a Broker-Dealer is no longer required to deliver a prospectus in connection with market-making or other trading activities.
The Company shall provide sufficient copies of the latest version of such Prospectus to Broker-Dealers promptly upon request at any time during such 180-day (or shorter as provided in the foregoing sentence) period in order to facilitate such
resales. 
 SECTION 4. Shelf Registration. 

(a) Shelf Registration. If (i) the Company is not required to file an Exchange Offer Registration Statement or to consummate
the Exchange Offer because the Exchange Offer is not permitted by applicable law or Commission policy (after the procedures set forth in Section 6(a) hereof have been complied with), (ii) for any reason the Exchange Offer is not
Consummated within 210 days after the Closing Date (or if such 210th day is not a Business Day, the next succeeding Business Day), or (iii) with respect to any Holder of Transfer Restricted Securities (A) such Holder is prohibited by
applicable law or Commission policy from participating in the Exchange Offer, or (B) such Holder may not resell the Exchange Securities acquired by it in the Exchange Offer to the public without delivering a prospectus and that the Prospectus
contained in the Exchange Offer Registration Statement is not appropriate or available for such resales by such Holder, or (C) such Holder is a Broker-Dealer and holds Initial Securities acquired directly from the Company or one of its
affiliates, then, upon such Holder’s request, the Company and the Guarantors shall 
 (x) cause to be filed
a shelf registration statement pursuant to Rule 415 under the Securities Act (the “Shelf Registration Statement”) on or prior to the earliest to occur of (1) the 45th day after the date on which the Company determines that it is not
required to file the Exchange Offer Registration Statement, (2) the 45th day after the date on which the Company receives notice from a Holder of Transfer Restricted Securities as contemplated by clause (iii) above, and (3) the 210th
day after the Closing Date (or if such 210th day is not a Business Day, the next succeeding Business Day) as promptly as practicable (such date being the “Shelf Filing Deadline”), which Shelf Registration Statement shall provide for
resales of all Transfer Restricted Securities the Holders of which shall have provided the information required pursuant to Section 4(b) hereof; and 

(y) use their reasonable best efforts to cause such Shelf Registration Statement to be declared effective by the
Commission on or before the 45th day after the Shelf Filing Deadline (or if such 45th day is not a Business Day, the next succeeding Business Day). 

Each of the Company and the Guarantors shall use its reasonable best efforts to keep such Shelf Registration Statement continuously
effective, supplemented and amended as required by the provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure that it is available for resales of Initial Securities by the Holders of Transfer Restricted Securities entitled
to the benefit of this Section 4(a), and to ensure that it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced

  

 -5- 








 
from time to time, for a period of the earlier of (i) the second anniversary of the Initial Placement and (ii) the date all the Initial Securities covered by such Shelf Registration
Statement have been sold pursuant to such Shelf Registration Statement. 
 (b) Provision by Holders of Certain Information in
Connection with a Shelf Registration Statement. No Holder of Transfer Restricted Securities may include any of its Transfer Restricted Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder
furnishes to the Company in writing, within 20 Business Days after receipt of a request therefor, such information as the Company may reasonably request for use in connection with any Shelf Registration Statement or Prospectus or preliminary
Prospectus included therein. Each Holder as to which any Shelf Registration Statement is being effected agrees to furnish promptly to the Company all information required to be disclosed in order to make the information previously furnished to the
Company by such Holder not materially misleading. 
 SECTION 5. Additional Interest. If (i) any Registration
Statement required by this Agreement is not filed with the Commission on or prior to the date specified for such filing in this Agreement, (ii) any Shelf Registration Statement required by this Agreement has not been declared effective by the
Commission on or prior to the date specified for such effectiveness in this Agreement, (iii) the Exchange Offer has not been Consummated (and a Shelf Registration has not been filed) within 210 days after the Closing Date with respect to the
Exchange Offer Registration Statement or (iv) any Registration Statement required by this Agreement is filed and declared effective but, following 210 days after the Closing Date, shall thereafter cease to be effective or fail to be usable for
its intended purpose without being succeeded immediately by a post-effective amendment to such Registration Statement that cures such failure and that is itself immediately declared effective (each such event referred to in clauses (i) through
(iv), a “Registration Default”), the Company hereby agrees that the interest rate borne by the Transfer Restricted Securities shall be increased by 0.25% per annum during the 90-day period immediately following the occurrence of any
Registration Default and shall increase by 0.25% per annum at the end of each subsequent 90-day period, but in no event shall such increase exceed 1.00% per annum. Following the cure of all Registration Defaults relating to any particular
Transfer Restricted Securities, the interest rate borne by the relevant Transfer Restricted Securities will be reduced to the original interest rate borne by such Transfer Restricted Securities; provided, however, that, if after any such
reduction in interest rate, a different Registration Default occurs, the interest rate borne by the relevant Transfer Restricted Securities shall again be increased pursuant to the foregoing provisions. 

All obligations of the Company and the Guarantors set forth in the preceding paragraph that are outstanding with respect to any Transfer
Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive until such time as all such obligations with respect to such security shall have been satisfied in full. 

SECTION 6. Registration Procedures. 

(a) Exchange Offer Registration Statement. In connection with the Exchange Offer, the Company and the Guarantors shall comply with
all of the provisions of Section 6(c) hereof, shall use their reasonable best efforts to effect such exchange to permit the sale of Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution
thereof, and shall comply with all of the following provisions: 
 (i) If in the reasonable opinion of counsel to
the Company there is a question as to whether the Exchange Offer is permitted by applicable law, each of the Company and the Guarantors hereby agrees to seek a no-action letter or other favorable decision from the Commission allowing the Company and
the Guarantors to Consummate an Exchange Offer for such Initial Securities. Each of the Company and the Guarantors hereby agrees to pursue the issuance of such a decision to the Commission staff level but shall not be required to take commercially
unreasonable action to effect a change of Commission policy. Each of the Company and the Guarantors hereby agrees, however, to (A) participate in telephonic conferences with the Commission, (B) deliver to the Commission staff an analysis
prepared by counsel to the Company setting forth the legal bases, if any, upon which such counsel has concluded that such an Exchange Offer should be permitted and (C) diligently pursue a favorable resolution by the Commission staff of such
submission. 
  

 -6- 








 (ii) As a condition to its participation in the Exchange Offer pursuant to
the terms of this Agreement, each Holder of Transfer Restricted Securities shall furnish, upon the request of the Company, prior to the Company Consummating the Exchange Offer, a written representation to the Company (which may be contained in the
letter of transmittal contemplated by the Exchange Offer Registration Statement) to the effect that (A) it is not an affiliate of the Company, (B) it is not engaged in, and does not intend to engage in, and has no arrangement or
understanding with any Person to participate in, a distribution of the Exchange Securities to be issued in the Exchange Offer and (C) it is acquiring the Exchange Securities in its ordinary course of business. In addition, all such Holders of
Transfer Restricted Securities shall otherwise cooperate in the Company’s preparations for the Exchange Offer. Each Holder hereby acknowledges and agrees that any Broker-Dealer and any such Holder using the Exchange Offer to participate in a
distribution of the securities to be acquired in the Exchange Offer (1) could not under Commission policy as in effect on the date of this Agreement rely on the position of the Commission enunciated in Morgan Stanley and Co., Inc.
(available June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in the Commission’s letter to Shearman & Sterling dated July 2, 1993, and similar no-action letters (which
may include any no-action letter obtained pursuant to clause (i) above), and (2) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction and that such a
secondary resale transaction should be covered by an effective registration statement containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K if the resales are of Exchange Securities
obtained by such Holder in exchange for Initial Securities acquired by such Holder directly from the Company. 
 (b) Shelf
Registration Statement. In connection with the Shelf Registration Statement, each of the Company and the Guarantors shall comply with all the provisions of Section 6(c) hereof and shall use its reasonable best efforts to effect such
registration to permit the sale of the Transfer Restricted Securities being sold in accordance with the intended method or methods 

 

 -7- 








 
of distribution thereof, and pursuant thereto each of the Company and the Guarantors will as promptly as practicable prepare and file with the Commission a Registration Statement relating to the
registration on any appropriate form under the Securities Act, which form shall be available for the sale of the Transfer Restricted Securities in accordance with the intended method or methods of distribution thereof. 

(c) General Provisions. In connection with any Registration Statement and any Prospectus required by this Agreement to permit the
sale or resale of Transfer Restricted Securities (including, without limitation, any Registration Statement and the related Prospectus required to permit resales of Initial Securities by Broker-Dealers), each of the Company and the Guarantors shall:

 (i) use its reasonable best efforts to keep such Registration Statement continuously effective and provide all
requisite financial statements, including, if required by the Securities Act or any regulation thereunder, financial statements of the Guarantors for the period specified in Section 3 or 4 hereof, as applicable; upon the occurrence of any event
that would cause any such Registration Statement or the Prospectus contained therein (A) to contain a material misstatement or omission or (B) not to be effective and usable for resale of Transfer Restricted Securities during the period
required by this Agreement, the Company shall file promptly an appropriate amendment to such Registration Statement, in the case of clause (A), correcting any such misstatement or omission, and, in the case of either clause (A) or (B), use its
reasonable best efforts to cause such amendment to be declared effective and such Registration Statement and the related Prospectus to become usable for their intended purpose(s) as promptly as practicable thereafter; 

(ii) prepare and file with the Commission such amendments and post-effective amendments to the applicable Registration
Statement as may be necessary to keep the Registration Statement effective for the applicable period set forth in Section 3 or 4 hereof, as applicable, or such shorter period as will terminate when all Transfer Restricted Securities covered by
such Registration Statement have been sold; cause the related Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and to comply fully with the
applicable provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during the
applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in such Registration Statement or supplement to the related Prospectus; 

(iii) advise the underwriter(s), if any, and selling Holders promptly and, if requested by such Persons, to confirm such
advice in writing, (A) when the related Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to any Registration Statement or any post-effective amendment thereto, when the same has become
effective, (B) of any request by the Commission for amendments to any Registration Statement or amendments or supplements to the related Prospectus or for additional information relating thereto, (C) of the issuance by the Commission

  

 -8- 








 
of any stop order suspending the effectiveness of any Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Transfer
Restricted Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes, (D) if the Registration Statement, the related Prospectus or any Prospectus supplement or post-effective
amendment, including any document incorporated by reference therein, contains an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein (in the case of any
Prospectus or Prospectus supplement, in light of the circumstances under which they were made) not misleading. If at any time the Commission shall issue any stop order suspending the effectiveness of any Registration Statement, or any state
securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or blue sky laws, each of the Company and the
Guarantors shall use its reasonable best efforts to obtain the withdrawal or lifting of such order as promptly as practicable. 

(iv) furnish without charge to each of the Initial Purchasers, each selling Holder named in any Registration Statement,
and each of the underwriter(s), if any, before filing with the Commission, copies of any Registration Statement or any Prospectus included therein or any amendments or supplements to any such Registration Statement or Prospectus (including all
documents incorporated by reference after the initial filing of such Registration Statement), which documents will be subject to the review of such Holders and underwriter(s) in connection with such sale, if any, for a period of at least five
Business Days, and the Company will not file any such Registration Statement or Prospectus or any amendment or supplement to any such Registration Statement or Prospectus (including all such documents incorporated by reference) to which an Initial
Purchaser of Transfer Restricted Securities covered by such Registration Statement or the underwriter(s), if any, shall reasonably object in writing within five Business Days after the receipt thereof (such objection to be deemed timely made upon
confirmation of telecopy transmission within such period). The objection of an Initial Purchaser or underwriter, if any, shall be deemed to be reasonable if such Registration Statement, amendment, Prospectus or supplement, as applicable, as proposed
to be filed, contains a material misstatement or omission; 
 (v) make available at reasonable times for
inspection by the Initial Purchasers, the managing underwriter(s), if any, participating in any disposition pursuant to such Registration Statement and any attorney or accountant retained by such Initial Purchasers or any of the underwriter(s), all
financial and other records, pertinent corporate documents and properties of each of the Company and the Guarantors and cause the Company’s and the Guarantors’ officers, directors and employees to supply all information reasonably
requested by any such Holder, underwriter, if any, attorney or accountant in connection with such Registration Statement or any post-effective amendment thereto subsequent to the filing thereof and prior to its effectiveness, and to participate in
meetings with investors to the extent reasonably requested by the managing underwriter(s), if any; provided, however, that any information that is reasonably and in good faith designated by the Company and the Guarantors in writing as
confidential at the time of delivery 
  

 -9- 








 
of such information shall be kept confidential by the Initial Purchasers or any such underwriter, attorney, accountant or other agent, unless (1) disclosure of such information is required
by court or administrative order or is necessary to respond to inquiries of regulatory authorities, (2) disclosure of such information is required by law (including any disclosure requirements pursuant to federal securities laws in connection
with the filing of such Registration Statement or the use of any Prospectus), (3) such information becomes generally available to the public other than as a result of a disclosure or failure to safeguard such information by such person or
(4) such information becomes available to such Initial Purchaser, underwriter, attorney, accountant or other agent from a source other than the Company or the Guarantors and such source is not known, after due inquiry, by the relevant Initial
Purchaser, underwriter, attorney, accountant or other agent to be bound by a confidentiality agreement or is not otherwise under a duty of trust to the Company or the Guarantors; 

(vi) if requested by any selling Holders or the underwriter(s), if any, incorporate as promptly as practicable in any
Registration Statement or related Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such selling Holders and underwriter(s), if any, may reasonably request to have included therein, including, without
limitation, information relating to the “Plan of Distribution” of the Transfer Restricted Securities, information with respect to the principal amount of Transfer Restricted Securities being sold to such underwriter(s), if any, the
purchase price being paid therefor and any other terms of the offering of the Transfer Restricted Securities to be sold in such offering; and make all required filings of such Prospectus supplement or post-effective amendment as promptly as
practicable after the Company is notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment; 

(vii) use its reasonable best efforts to cause the Transfer Restricted Securities covered by any Registration Statement to
be rated with the appropriate rating agencies, if so reasonably requested by the Holders of a majority in aggregate principal amount of Securities covered thereby or the underwriter(s), if any; 

(viii) deliver to each selling Holder and each of the underwriter(s), if any, without charge, as many copies of the
related Prospectus (including each preliminary Prospectus) and any amendment or supplement thereto as such Persons may reasonably request; each of the Company and the Guarantors hereby consents to the use of such Prospectus and any amendment or
supplement thereto by each of the selling Holders and each of the underwriter(s), if any, in connection with the offering and the sale of the Transfer Restricted Securities covered by such Prospectus or any amendment or supplement thereto;

 (ix) enter into such customary agreements (including an underwriting agreement), and make such representations
and warranties, and take all such other actions in connection therewith in order to expedite or facilitate the disposition of the Transfer Restricted Securities pursuant to any Registration Statement contemplated by this Agreement, all to such
extent as may be reasonably requested by any Initial Purchaser or by 
  

 -10- 








 
any Holder of Transfer Restricted Securities or underwriter, if any, in connection with any sale or resale pursuant to any Registration Statement contemplated by this Agreement; and if an
underwriting agreement is entered into and the registration is an Underwritten Registration, each of the Company and the Guarantors shall: 

(A) furnish to the Initial Purchaser, each selling Holder and each underwriter, if any, in such substance and scope as
they may reasonably request and as are customarily made by issuers to underwriters in primary underwritten offerings, upon the date the Company Consummates the Exchange Offer or, if applicable, the date of the effectiveness of the Shelf Registration
Statement: 
 (1) a certificate, dated the date the Company Consummates the Exchange Offer or the date of
effectiveness of the Shelf Registration Statement, as the case may be, signed by the Chief Financial Officer of the Company, confirming, as of the date thereof, the matters set forth in paragraphs (i), (ii) and (iii) of Section 5(e)
of the Purchase Agreement and such other matters as such parties may reasonably request; and 
 (2) an opinion,
dated the date the Company Consummates the Exchange Offer or the date of effectiveness of the Shelf Registration Statement, as the case may be, of counsel for the Company and the Guarantors, covering the matters set forth in Section 5(c) of the

 (B) use its reasonable
best efforts to cause to have delivered a customary comfort letter, dated the date of effectiveness of the Shelf Registration Statement, from the Company’s independent accountants, in the customary form and covering matters of the type

Agreement, without exception; 
 (C) set forth in full or incorporate by reference in the underwriting agreement,
if any, the indemnification provisions and procedures of Section 8 hereof with respect to all parties to be indemnified pursuant to said Section; and 

(D) deliver such other documents and certificates as may be reasonably requested by such parties to evidence compliance
with Section 6(c)(ix)(A) hereof and with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company or any of the Guarantors pursuant to this Section 6(c)(ix), if any. 

If at any time the representations and warranties of the Company and the Guarantors contemplated in
Section 6(c)(ix)(A)(1) hereof cease to be true and correct, the Company or the Guarantors shall so advise the Initial Purchasers and the underwriter(s), if any, and each selling Holder as promptly as practicable and, if reasonably requested by
such Persons, shall confirm such advice in writing; 
  

 -11- 








 (x) prior to any public offering of Transfer Restricted Securities,
cooperate with the selling Holders, the underwriter(s), if any, and their respective counsel in connection with the registration and qualification of the Transfer Restricted Securities under the state securities or blue sky laws of such
jurisdictions as the selling Holders or underwriter(s), if any, may request and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the Shelf
Registration Statement; provided, however, that none of the Company or the Guarantors shall be required to register or qualify as a foreign corporation where it is not then so qualified or to take any action that would subject it to the
service of process in suits or to taxation, other than as to matters and transactions relating to any Registration Statement, in any jurisdiction where it is not then so subject;

registered in the name of such Holder or in the name of the purchaser(s) of such Securities, as the case may be; and in return, the Initial Securities held by such Holder shall be surrendered to the Company for cancellation; 

(xii) cooperate with the selling Holders and the underwriter(s), if any, to facilitate the timely preparation and delivery
of certificates representing Transfer Restricted Securities to be sold and not bearing any restrictive legends; and enable such Transfer Restricted Securities to be in such denominations and registered in such names as the Holders or the
underwriter(s), if any, may request at least two Business Days prior to any sale of Transfer Restricted Securities made by such Holders or underwriter(s); 

(xiii) use its reasonable best efforts to cause the Transfer Restricted Securities covered by any 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(s), if any, to consummate the disposition of such Transfer Restricted Securities,
subject to the proviso contained in Section 6(c)(x) hereof; 
 (xiv) if any fact or event contemplated by
Section 6(c)(iii)(D) hereof shall exist or have occurred, prepare a supplement or post-effective amendment to any Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document
so that, as thereafter delivered to the purchasers of Transfer Restricted Securities, such Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein not
misleading; 
 (xv) provide a CUSIP number for all Securities not later than the effective date of any
Registration Statement covering such Securities and provide the trustee under the Indenture with printed certificates for such Securities which are in a form eligible for deposit with The Depository Trust Company and take all other action necessary
to ensure that all such Securities are eligible for deposit with The Depository Trust Company; 
  

 -12- 








 (xvi) cooperate and assist in any filings required to be made with FINRA and
in the performance of any due diligence investigation by any underwriter (including any “qualified independent underwriter”) that is required to be retained in accordance with the rules and regulations of FINRA; 

(xvii) otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the Commission,
and make generally available to its security holders, as promptly as practicable, a consolidated earnings statement (which need not be audited) satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder for the
twelve-month period (A) commencing at the end of any fiscal quarter in which Transfer Restricted Securities are sold to underwriters in a firm commitment or best efforts Underwritten Offering or (B) if not sold to underwriters in such an
offering, commencing on the first day of the first fiscal quarter after the effective date of the Registration Statement or the effective date of each post-effective amendment to such Registration Statement; 

(xviii) cause the Indenture to be qualified under the Trust Indenture Act 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 Securities to effect such changes to the Indenture as may be required for such Indenture to be so
qualified in accordance with the terms of the Trust Indenture Act; and to execute, and use its reasonable best efforts to cause the Trustee to execute, all documents that may be required to effect such changes and all other forms and documents
required to be filed with the Commission to enable such Indenture to be so qualified in a timely manner; 
 (xix)
cause all Securities covered by any Registration Statement to be listed on each national securities exchange on which similar securities issued by the Company are then listed if requested by the Holders of a majority in aggregate principal amount of
Initial Securities or the managing underwriter(s), if any; and 
 (xx) provide promptly to each Holder upon
request each document filed with the Commission pursuant to the requirements of Section 13 and Section 15 of the Exchange Act. 

Each Holder agrees by acquisition of a Transfer Restricted Security that, upon receipt of any notice from the Company of the existence of
any fact of the kind described in Section 6(c)(iii)(D) hereof, such Holder will forthwith discontinue disposition of Transfer Restricted Securities pursuant to the applicable Registration Statement until such Holder’s receipt of the copies
of the supplemented or amended related Prospectus contemplated by Section 6(c)(xiv) hereof, or until it is advised in writing (the “Advice”) by the Company that the use of the Prospectus may be resumed, and has received copies of any
additional or supplemental filings that are incorporated by reference in such Prospectus. If so directed by the Company, each Holder will deliver to the Company (at the Company’s expense) all copies, other than permanent file copies

  

 -13- 








 
then in such Holder’s possession, of the Prospectus covering such Transfer Restricted Securities that was current at the time of receipt of such notice. In the event the Company shall give
any such notice, the time period regarding the effectiveness of such Registration Statement set forth in Sections 3 or 4 hereof, as applicable, shall be extended by the number of days during the period from and including the date of the giving of
such notice pursuant to Section 6(c)(iii)(D) hereof to and including the date when each selling Holder covered by such Registration Statement shall have received the copies of such supplemented or amended Prospectus contemplated by
Section 6(c)(xiv) hereof or shall have received the Advice; provided, however, that no such extension shall be taken into account in determining whether Additional Interest is due pursuant to Section 5 hereof or the amount of such
Additional Interest, it being agreed that the Company’s option to suspend use of any Registration Statement pursuant to this paragraph shall be treated as a Registration Default for purposes of Section 5 hereof. 

SECTION 7. Registration Expenses. 

(a) All reasonable and customary expenses incident to the Company’s and the Guarantors’ performance of or compliance with this
Agreement will be borne by the Company and the Guarantors, jointly and severally, regardless of whether a Registration Statement becomes effective, including, without limitation: (i) all registration and filing fees and expenses (including
filings made by any Initial Purchaser or Holder with FINRA (and, if applicable, the fees and expenses of any “qualified independent underwriter” and its counsel that may be required by the rules and regulations of FINRA)); (ii) all
fees and expenses of compliance with federal securities and state securities or blue sky laws; (iii) all printing (including printing certificates for the Exchange Securities to be issued in the Exchange Offer and printing of Prospectuses),
messenger, delivery and telephone expenses; (iv) all fees and disbursements of counsel for the Company, the Guarantors and, subject to Section 7(b) hereof, the Holders of Transfer Restricted Securities; (v) all application and filing
fees in connection with listing the Exchange Securities on a securities exchange or automated quotation system pursuant to the requirements thereof; and (vi) all fees and disbursements of independent certified public accountants of the Company
and the Guarantors (including the expenses of any special audit and comfort letters required by or incident to such performance). 

Each of the Company and the Guarantors will, in any event, bear its internal expenses (including, without limitation, all salaries and
expenses of its officers and employees performing legal or accounting duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by the Company or the Guarantors. Each Holder shall pay all
underwriting discounts, commissions, brokerage commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s Transfer Restricted Securities pursuant to the Shelf Registration Statement. 

(b) In connection with any Shelf Registration Statement, the Company and the Guarantors, jointly and severally, will reimburse the
Initial Purchasers and the Holders of Transfer Restricted Securities being resold pursuant to the Shelf Registration Statement, as applicable, for the reasonable fees and disbursements of not more than one counsel, who shall be Cahill
Gordon & Reindel LLP or such other counsel reasonably acceptable to the Company and the Guarantors as may be chosen by the Holders of a majority in principal amount of the Transfer Restricted Securities for whose benefit such
Registration Statement is being prepared.

 SECTION 8. Indemnification. 

(a) The Company and each Guarantor, jointly and severally, agree to indemnify and hold harmless (i) each Holder and (ii) each
Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) any Holder (any of the Persons referred to in this clause (ii) being hereinafter referred to as a
“controlling person”) and (iii) the respective officers, directors, partners, employees, representatives and agents of any Holder or any controlling person (any Person referred to in clause (i), (ii) or (iii) may hereinafter
be referred to as an “Indemnified Holder”), to the fullest extent lawful, from and against any and all losses, claims, damages, liabilities, judgments, actions and expenses (including, without limitation, and as incurred, reimbursement of
all reasonable costs of investigating, preparing, pursuing, settling, compromising, paying or defending any claim or action, or any investigation or proceeding by any governmental agency or body, commenced or threatened, including the reasonable
fees and expenses of counsel to any Indemnified Holder), joint or several, directly or indirectly caused by, related to, based upon, arising out of or in connection with 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 omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading,
except insofar as such losses, claims, damages, liabilities or expenses are caused by an untrue statement or omission or alleged untrue statement or omission that is made in reliance upon and in conformity with information relating to any of the
Holders furnished in writing to the Company by any of the Holders expressly for use therein. This indemnity agreement shall be in addition to any liability which the Company or any Guarantor may otherwise have. 

In case any action or proceeding (including any governmental or regulatory investigation or proceeding) shall be brought or asserted
against any of the Indemnified Holders with respect to which indemnity may be sought against the Company or any Guarantor, such Indemnified Holder (or the Indemnified Holder controlled by such controlling person) shall promptly notify the Company
and the Guarantors in writing; provided, however, that the failure to give such notice shall not relieve any of the Company or the Guarantors of its obligations pursuant to this Agreement except to the extent the Company or such Guarantor is
materially prejudiced thereby. In case any such action is brought against any of the Indemnified Holders and such Indemnified Holder seeks or intends to seek indemnity from the Company or the Guarantors, the Company and the Guarantors will be
entitled to participate in and, to the extent that they shall elect, jointly, by written notice delivered to such Indemnified Holders promptly after receiving the aforesaid notice from such Indemnified Holders, to assume the defense thereof with
counsel reasonably satisfactory to such Indemnified Holders; provided, however, if the defendants in any such action include both the Indemnified Holders and the Company or the Guarantors, and any Indemnified Holder shall have reasonably
concluded (based upon advice of counsel) that a conflict may arise between the positions of the Company or the Guarantors and such Indemnified Holder in conducting the defense of any such action, such Indemnified Holder shall have the right to
select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such Indemnified Holder. Upon receipt of notice from the Company 

 

 -15- 








 
and the Guarantors to the Indemnified Holders of the Company and the Guarantors’ election to so assume the defense of such action and approval by the Indemnified Holders of counsel, the
Company and the Guarantors will not be liable to such Indemnified Holders under this Section 8 for any legal or other expenses subsequently incurred by such Indemnified Holders in connection with the defense thereof unless (i) an
Indemnified Holder shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the Company and the Guarantors shall not be liable for the reasonable fees and expenses
of more than one separate counsel (together with local counsel) representing all such similarly situated Indemnified Holders who are parties to such action) or (ii) the Company and the Guarantors shall not have employed counsel reasonably
satisfactory to the Indemnified Holders to represent the Indemnified Holders within a reasonable time after notice of commencement of the action, in each of which cases the reasonable fees and expenses of one counsel (together with local counsel)
for all such Indemnified Holders shall be at the expense of the Company and the Guarantors. It is understood and agreed that the Company and the Guarantors shall not, in connection with any action or proceeding or separate but substantially similar
or related actions or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at
any time for such Indemnified Holders, which firm shall be designated by the Holders. Each Indemnified Holder, as a condition to indemnification hereunder, shall use all reasonable efforts to cooperate with the Company or the Guarantors in the
defense of any such action or claim. The Company and the Guarantors shall not be liable for any settlement of any such action or proceeding effected without the Company’s and the Guarantors’ prior written consent, which consent shall not
be withheld unreasonably, but if settled with such consent or there be a final judgment for the plaintiff, each of the Company and the Guarantors agrees to indemnify and hold harmless any Indemnified Holder from and against any loss, claim, damage,
liability or expense by reason of such settlement or judgment. The Company and the Guarantors shall not, without the prior written consent of each Indemnified Holder, settle or compromise or consent to the entry of judgment in or otherwise seek to
terminate any pending or threatened action, claim, litigation or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not any Indemnified Holder is a party thereto), unless such settlement, compromise,
consent or termination includes an unconditional release of each Indemnified Holder from all liability arising out of such action, claim, litigation or proceeding. 

(b) Each Holder of Transfer Restricted Securities agrees, severally and not jointly, to indemnify and hold harmless the Company, each
Guarantor, each of their respective directors, officers and employees, and any Person controlling (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) the Company or any Guarantor, and the respective
officers, directors, partners, employees, representatives and agents of each such Person, to the same extent as the foregoing indemnity from the Company and the Guarantors to each of the Indemnified Holders, but only with respect to claims and
actions based on information relating to such Holder furnished in writing by such Holder expressly for use in any Registration Statement. In case any action or proceeding shall be brought against the Company, the Guarantors or their respective
directors or officers or any such controlling person in respect of which indemnity may be sought against a Holder of Transfer Restricted Securities, such Holder shall have the rights and duties given the Company and the Guarantors, and the Company,
the Guarantors, its their respective directors and officers and such controlling person shall have the rights and duties given to each Holder by the preceding paragraph. 
  


 -16- 








 (c) If the indemnification provided for in this Section 8 is unavailable to an
indemnified party under Section 8(a) or (b) hereof (other than by reason of exceptions provided in those Sections) in respect of any losses, claims, damages, liabilities, judgments, actions or expenses referred to therein, then each
applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is
appropriate to reflect the relative benefits received by the Company and the Guarantors, on the one hand, and the Holders, on the other hand, from the Initial Placement (which in the case of the Company and the Guarantors shall be deemed to be equal
to the total gross proceeds to the Company and the Guarantors from the Initial Placement), the amount of Additional Interest which did not become payable as a result of the filing of a Registration Statement resulting in such losses, claims,
damages, liabilities, judgments actions or expenses, and such Registration Statement, or if such allocation is not permitted by applicable law, the relative fault of the Company and the Guarantors, on the one hand, and the Holders, on the other
hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of the Company and the Guarantors on the one
hand and of the Indemnified Holders on the other 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 any of the Guarantors, on the one hand, or the Indemnified Holders, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such
statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in the second paragraph of
Section 8(a) hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. 

The Company, each Guarantor and each Holder of Transfer Restricted Securities agree that it would not be just and equitable if
contribution pursuant to this Section 8(c) were determined by pro rata allocation (even if the Holders of Transfer Restricted Securities were treated as one entity for such purpose) or by any other method of allocation which does not take
account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 8, none of the Holders shall be required to contribute, in the aggregate, any amount in excess of the amount by which the total discount received by such Holder with respect to the Initial
Securities exceeds the amount of any damages which such Holder has 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 Holders’ obligations to contribute pursuant to this Section 8(c) are
several in proportion to the respective principal amount of Initial Securities held by each of the Holders hereunder and not joint. 
  

 -17- 








 SECTION 9. Rule 144A. Each of the Company and the Guarantors hereby agrees with
each Holder, for so long as any Transfer Restricted Securities remain outstanding, to make available to any Holder or beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such
Transfer Restricted Securities from such Holder or beneficial owner, the information required by Rule 144A(d)(4) under the Securities Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A under the Securities
Act. 
 SECTION 10. Participation in Underwritten Registrations. No Holder may participate in any Underwritten
Registration hereunder unless such Holder (a) agrees to sell such Holder’s Transfer Restricted 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 reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements. 

SECTION 11. Selection of Underwriters. The Holders of Transfer Restricted Securities covered by the Shelf Registration
Statement who desire to do so may sell such Transfer Restricted Securities in an Underwritten Offering. In any such Underwritten Offering, the investment banker(s) and managing underwriter(s) that will administer such offering will be selected by
the Holders of a majority in aggregate principal amount of the Transfer Restricted Securities included in such offering; provided, however, that such investment banker(s) and managing underwriter(s) must be reasonably satisfactory to the
Company. 
 SECTION 12. Miscellaneous. 

(a) Remedies. Each of the Company and the Guarantors hereby agrees that monetary damages would not be adequate compensation for
any loss incurred by reason of a breach by it of the provisions of this Agreement and hereby agree to waive the defense in any action for specific performance that a remedy at law would be adequate. 

(b) No Inconsistent Agreements. Each of the Company and the Guarantors will not on or after the date of this Agreement enter into
any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. Neither the Company nor any of the Guarantors has previously entered into
any agreement granting any registration rights with respect to its securities to any Person. 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
Company’s or any of the Guarantors’ securities under any agreement in effect on the date hereof. 
 (c) Adjustments
Affecting the Securities. The Company will not take any action, or permit any change to occur, with respect to the Securities that would materially and adversely affect the ability of the Holders to Consummate any Exchange Offer. 

 

 -18- 








 (d) Amendments and Waivers. The provisions of this Agreement may not be amended,
modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given unless the Company has (i) in the case of Section 5 hereof and this Section 12(d)(i), obtained the written consent of
Holders of all outstanding Transfer Restricted Securities and (ii) in the case of all other provisions hereof, obtained the written consent of Holders of a majority of the outstanding principal amount of Transfer Restricted Securities
(excluding any Transfer Restricted Securities held by the Company or its Affiliates). Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof that relates exclusively to the rights of Holders whose securities are
being tendered pursuant to the Exchange Offer and that does not affect directly or indirectly the rights of other Holders whose securities are not being tendered pursuant to such Exchange Offer may be given by the Holders of a majority of the
outstanding principal amount of Transfer Restricted Securities being tendered or registered; provided, however, that, with respect to any matter that directly or indirectly affects the rights of any Initial Purchaser hereunder, the Company
shall obtain the written consent of each such Initial Purchaser with respect to which such amendment, qualification, supplement, waiver, consent or departure is to be effective. 

(e) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery,
