Offer, (ii) shall use its reasonable best efforts to cause such Registration Statement to become effective, (iii) in connection with the foregoing, shall use reasonable best efforts to file (A) all pre-effective amendments to such

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 shall use its reasonable best efforts to cause the Exchange Offer Registration Statement to be effective
continuously and shall keep the Exchange Offer open for a period of not less than the minimum period required under applicable federal and state securities laws to Consummate the Exchange Offer; provided, however, that in no event shall such
period be less than 30 days after the date notice of the Exchange Offer is mailed to the Holders. The Company shall cause the Exchange Offer to comply in all material respects 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 no later than 360 days after the Closing Date.

 (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 (i) 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, and (ii) 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. 
 The
Company 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 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 the time period specified in Section 3 hereof, or (iii) any
Holder of Transfer Restricted Securities notifies the Company on or before the 270th day after the Closing Date that (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 shall 
 (x) use its reasonable best efforts to cause to
be filed a shelf registration statement pursuant to Rule 415 under the Securities Act, which may be an amendment to the Exchange Offer Registration Statement (in either event, the “Shelf Registration Statement”), 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 its reasonable best efforts to cause such Shelf Registration Statement to be declared effective by the Commission on or before the
360th day after the Closing Date. 
 The Company shall use its 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 from time to time, for a period of at least two
years following the Closing Date (or shorter period that will terminate when 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 the 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) the Exchange Offer has not
been Consummated within 360 Business Days after the Closing Date or (ii) the Company is obligated to file a Shelf Registration Statement and such Shelf Registration Statement has not been declared effective by the Commission within 360 days
after the Closing Date or such Shelf Registration Statement is declared effective but 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) and (ii), 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 an additional 0.25% per annum during the subsequent
90-day period, but in no event shall such increase exceed 0.50% 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
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 shall comply with all of the provisions of
Section 6(c) hereof, shall use its 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, the Company hereby agrees to seek a no-action letter or other favorable decision from the Commission allowing the Company to Consummate an Exchange Offer for such Initial Securities and 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. 
 (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 Consummation thereof, 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, the Company 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 of distribution thereof, and pursuant thereto the Company will in accordance with Section 4(a) hereof
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), the Company shall: 
 (i) use its reasonable best efforts to keep such Registration Statement continuously
effective and provide all requisite financial statements 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 soon as practicable thereafter; 

 (ii) use its reasonable best efforts to 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 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 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 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 the Registration Statement or amendments or supplements to the Prospectus or for additional information relating thereto, (C) of the issuance by the Commission of any stop order
suspending the effectiveness of the 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) of the existence of any fact or the happening of any event that makes any statement of a material fact made in the Registration Statement, the Prospectus, any amendment or
supplement thereto, or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the Registration Statement or the Prospectus in order to make the statements therein not misleading. If at
any time the Commission shall issue any stop order suspending the effectiveness of the 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, the Company shall use its reasonable best efforts to obtain the withdrawal or lifting of such order at the earliest possible time; 
 (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 and comment 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 the Company and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such Holder, underwriter, 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 requested by the managing
underwriter(s), if any; provided; however, that any information that is designated by the Company, in good faith, as confidential at the time of delivery of such information shall be kept confidential by the Holders or any such
underwriter, attorney or accountant, unless such disclosure is made in connection with a court proceeding or required by law, or such information becomes available to the public generally or through a third party without an accompanying obligation
of confidentiality; 
 (vi) if requested by any selling Holders or the underwriter(s), if any, promptly incorporate in any
Registration Statement or 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), 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 soon as practicable after the
Company is notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment; 
 (vii)
cause the Transfer Restricted Securities covered by the Registration Statement to be rated with the appropriate rating agencies, if so 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 Prospectus (including each preliminary prospectus) and any amendment or supplement thereto as such Persons reasonably may request; the Company hereby consents to the use of the 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 the Prospectus or any amendment or supplement thereto; 

 (ix) enter into such customary agreements (including an underwriting agreement), and make
such customary representations and warranties, and take all such other reasonable 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 any Holder of Transfer Restricted Securities or underwriter in connection with any sale or resale pursuant to any Registration Statement
contemplated by this Agreement; and whether or not an underwriting agreement is entered into and whether or not the registration is an Underwritten Registration, the Company shall: 
 (A) furnish to each 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 of the Consummation of the Exchange Offer or, if applicable, the effectiveness of the Shelf Registration Statement:

 (1) a certificate, dated the date of Consummation of the Exchange Offer or the date of effectiveness of the Shelf
Registration Statement, as the case may be, signed by (y) the President or any Vice President and (z) a principal financial or accounting 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; 
 (2) an opinion, dated the date of Consummation of the Exchange Offer or the date of effectiveness of the Shelf Registration Statement, as the case may be, of counsel for the Company, covering the matters set forth in
Exhibit A of the Purchase Agreement and such other matter as such parties may reasonably request; and 
 (3) 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 customarily requested to be covered in comfort letters by
underwriters in connection with primary underwritten offerings, and covering or affirming the matters set forth in the comfort letters delivered pursuant to Section 5(a) of the Purchase Agreement, without exception; 
 (B) 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 such Section; and 
 (C) 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 pursuant to this Section 6(c)(ix), if any. 

 If at any time the representations and warranties of the Company contemplated in
Section 6(c)(ix)(A)(1) hereof cease to be true and correct, the Company shall so advise the Initial Purchasers and the underwriter(s), if any, and each selling Holder promptly and, if requested by such Persons, shall confirm such advice in
writing; 
 (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 the Company shall not 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 the Registration Statement, in any jurisdiction where it is not then so subject; 
 (xi)
shall issue, upon the request of any Holder of Initial Securities covered by the Shelf Registration Statement, Exchange Securities having an aggregate principal amount equal to the aggregate principal amount of Initial Securities surrendered to the
Company by such Holder in exchange therefor or being sold by such Holder; such Exchange Securities to be registered in the name of such Holder or in the name of the purchaser(s) of such Securities, as the case may be; 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 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(s), if any, to consummate the disposition of such Transfer Restricted Securities, subject to the
proviso contained in Section 6(c) (xii) hereof; 
 (xiv) if any fact or event contemplated by
Section 6(c)(iii)(D) hereof shall exist or have occurred, use its reasonable best efforts to prepare a supplement or post-effective amendment to the 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, the 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 the
Registration Statement covering such Securities and provide the Trustee under the Indenture with 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; 
 (xvi) cooperate and assist in
any filings required to be made with the NASD 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 the NASD; 
 (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 soon as practicable, a consolidated earnings statement meeting the requirements of Rule 158 (which need not be audited) 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, beginning
with the first month of the Company’s first fiscal quarter commencing after the effective date of the 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 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; and 
 (xix) cause all Securities covered by the Registration Statement to be listed on each securities exchange or automated quotation system 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. 
 Each Holder agrees by acquisition of a Transfer Restricted Security that, upon receipt of any notice from the Company of (a) the existence of any
fact of the kind described in Section 6(c)(iii)(D) hereof or (b) its good faith determination that the Company had a valid business reason, including that the continued effectiveness of the Registration Statement and use of the Prospectus
would require disclosure of confidential information related to a material acquisition or divestiture of assets or a material corporate transaction or event, to suspend the use of the Prospectus, 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 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 the 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 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 Section 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 the 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 a 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 expenses incident to the Company’s performance of or compliance with this Agreement will be borne by the Company, 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 the NASD (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 the NASD)); (ii) all fees and expenses of compliance with federal securities and state securities or blue sky laws; (iii) all expenses of printing (including printing
certificates for the Exchange Securities to be issued in the Exchange Offer and printing of Prospectuses), messenger and delivery services and telephone; (iv) all fees and disbursements of counsel for the Company 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 (including the expenses of any special audit and comfort letters required by or incident to such performance). 
 The Company will, in any event, bear its internal expenses, the expenses of any annual audit and the fees and expenses of any Person, including special
experts, retained by the Company. 
 (b) In connection with any Registration Statement required by this Agreement (including, without
limitation, the Exchange Offer Registration Statement and the Shelf Registration Statement), the Company will reimburse the Initial Purchasers and the Holders of Transfer Restricted Securities being tendered in the Exchange Offer and/or resold
pursuant to the “Plan of Distribution” contained in the Exchange Offer Registration Statement or registered pursuant to the Shelf Registration Statement, as applicable, for the reasonable fees and disbursements of not more than one
counsel, who shall be Simpson Thacher & Bartlett LLP or such other counsel 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 agrees 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 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, such Indemnified
Holder (or the Indemnified Holder controlled by such controlling person) shall promptly notify the Company in writing; provided, however, that the failure to give such notice shall not relieve the Company of its obligations pursuant to this
Agreement to the extent the Company is not prejudiced as a proximate result of such omission through the forfeiture of substantive rights or defenses. In case any such action shall be brought against any Indemnified Holder and it shall notify the
Company of the commencement thereof, the Company shall be entitled to participate therein and, to the extent that it shall wish, to assume the defense thereof, with counsel satisfactory to such Indemnified Holder (who shall not, except with the
consent of the Indemnified Holder, be counsel to the Company), and, after notice from the Company to such Indemnified Holder of its election so to assume the defense thereof, the Company shall not be liable to such Indemnified Holder under this
subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such Indemnified Holder, in connection with the defense thereof other than reasonable costs of investigation; provided, however,
that if the Indemnified Holder shall have been advised by counsel that there are actual or potential conflicting interests between the Company and the Indemnified Holder, including situations in which there are one or more legal defenses available
to the Indemnified Holder that are different from or additional to those available to the Company, the Company shall not be entitled to assume the defense of such action and the Indemnified Holder shall have the right to employ its own counsel, in
which event the reasonable fees and expenses of such separate counsel, including local counsel, shall be borne by the Company and reimbursed to the Indemnified Holder as incurred. The Company 

 
shall not, without the written consent of the Indemnified Holder, effect the settlement or compromise of, or consent to the entry of any judgment with
respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the Indemnified Holder is an actual or potential party to such action or claim) unless such settlement,
compromise or judgment (i) includes an unconditional release of the Indemnified Holder from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of any Indemnified Holder. 
 (b) Each Holder of Transfer Restricted Securities agrees, severally and not jointly, to
indemnify and hold harmless the Company, its directors, its officers who sign a Registration Statement, and any Person controlling (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) the Company, and
the officers, directors, partners, employees, representatives and agents of each such Person, to the same extent as the foregoing indemnity from the Company 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 or its 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 Company, its directors and officers and such controlling person shall have
the rights and duties given to each Holder by the preceding paragraph. 
 (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, on the one hand, and the Holders, on the other hand, from the Initial Placement (which in the case of the Company shall be deemed to be equal to the total gross
proceeds to the Company from the Initial Placement), or if such allocation is not permitted by applicable law, the relative fault of the Company, 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 on the one hand and of the Indemnified Holder 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, 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 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 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 (and its related Indemnified 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. 
 SECTION 9. Rule 144A. The Company 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. The Company 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. The Company 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. The Company has not 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 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. 
 (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, insofar as they
affect the rights or obligations of Holders of any series of Transfer Restricted Securities, 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 of that series 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 of that
series (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 of a series of
Transfer Restricted Securities 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 of that series 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, first-class
